Siding Installation Permits in Boise
A complete guide to permit requirements, energy code triggers, fire zone regulations, historic district rules, and inspections for siding installation in Boise, Ada County, and the Treasure Valley.
Quick answer
Yes. Inside Boise city limits, re-siding is permitted work: the City issues it under Permit 428, the Residential Roofing, Siding and Windows application, and that applies to a like-for-like replacement as much as to a change of material.
Inside Boise city limits, yes. The City issues re-siding under Permit 428, the Residential Roofing, Siding and Windows application, and that covers a straight like-for-like replacement as well as a change of material. This is worth stating plainly because most of what is written online about siding being permit-exempt is written for other jurisdictions. What varies with scope is everything that travels with the permit — which reviews apply, which inspections are called, and how the project is valued for the fee.
Adds Review to the Permit
Changing siding material type
Switching from vinyl to fiber cement, wood to metal, or any material-type change alters the wall assembly and requires a building permit. Different materials have different weight, attachment, and fire-rating characteristics that must be reviewed.
Adding or modifying exterior insulation
Installing rigid foam insulation, mineral wool boards, or any continuous insulation beneath new siding changes the wall's R-value and triggers energy code compliance. This is the most common permit trigger for siding projects in the Boise area.
Structural sheathing replacement
If the existing OSB or plywood sheathing is rotted, damaged, or needs replacement, this is structural work that requires a permit. The sheathing is part of the home's lateral bracing system.
Adding new wall penetrations
Installing new exhaust vents, dryer vents, electrical outlets, light fixtures, or hose bibs through the exterior wall requires appropriate permits (building, electrical, plumbing, or mechanical).
Work in historic overlay districts
Homes in Boise's historic preservation districts (North End, portions of the Bench, and other designated areas) require a Certificate of Appropriateness from the Boise Historic Preservation Commission before any exterior changes.
Hillside and Wildland Urban Interface areas
Permit 428 states that roof coverings and siding installed in the hillside area or in a Wildland Urban Interface area must be non-combustible as regulated by the City of Boise Fire Prevention Code. Permit review is where that gets checked, and the Fire Code official has the final say on the assembly.
Maintenance, Not Re-Siding
What this column is not
A like-for-like re-side is not on this list. Replacing vinyl with vinyl or fiber cement with fiber cement across a wall is still re-siding, and in Boise it still goes through Permit 428. The items below are maintenance on siding that stays in place.
Painting or staining existing siding
Repainting or re-staining your current siding does not require a permit, even if you change the color (unless HOA rules apply or the home is in a historic district).
Minor siding repairs (same material)
Replacing a few damaged boards, panels, or shingles with matching material. Patching small areas of siding that have been damaged by weather, impact, or woodpeckers.
Replacing trim and fascia (non-structural)
Swapping deteriorated trim boards, corner boards, and fascia with new material when no structural members are affected.
Caulking and weathersealing
Re-caulking joints, replacing deteriorated sealant around windows and doors, and general weatherproofing maintenance.
Power washing and surface preparation
Cleaning existing siding surfaces in preparation for painting or to remove mildew, dirt, and oxidation. No permit required for cleaning.
Ada County rules: Unincorporated Ada County works to the same Idaho Residential Code as Boise — Idaho has adopted the 2018 IRC — but permits are processed through Ada County Development Services rather than the City, and processing times differ.
Canyon County rules: Canyon County (Nampa, Caldwell) has its own development services department. The code is the same statewide code, but the application process differs, so confirm the requirements with Canyon County Development Services for properties west of the Ada County line.
How the Boise fee is calculated: the permit fee is taken from the declared value of the work against the tiers in Table 1-A of the City's fee schedule, with a plan review fee of 20 percent added on residential work. On the current schedule, a project valued between $2,001 and $25,000 is $70.76 plus $12.71 per additional $1,000; $25,001 to $50,000 is $362.80 plus $9.30 per additional $1,000; and anything above $100,000 is $913.09 plus $5.17 per additional $1,000. The 65 percent plan review figure that turns up in contractor write-ups is the commercial rate, not the residential one. Fee schedules change, so treat these as the figures to check rather than the figures to budget from.
One of the most misunderstood aspects of siding installation in Boise is the energy code trigger. Adding insulation beneath new siding is a genuine improvement to the wall, but it brings the project under the residential energy provisions Idaho has adopted alongside the 2018 International Residential Code, and that means an additional review and an additional inspection on a permit you were already pulling.
What Triggers Energy Code
Rigid foam insulation (XPS, EPS, Polyiso)
Adding any thickness of rigid foam board between the sheathing and new siding triggers the energy review. Boise is in Climate Zone 5, where the prescriptive wood-frame wall requirement is R-20 in the cavity, or R-13 in the cavity plus R-5 continuous — the two are alternatives, not a single combined requirement, and the second is the one a re-side is usually reaching for.
Mineral wool continuous insulation
Products like Rockwool ComfortBoard provide continuous insulation and also trigger the energy code. Mineral wool offers fire resistance advantages and is becoming increasingly popular in Boise's foothills WUI zones.
Insulated siding products
Insulated vinyl siding (with foam backing) and some engineered wood products with integrated insulation also count as adding continuous insulation and trigger energy code requirements.
WRB (Weather-Resistive Barrier) Requirements
Any siding installation, whether permit-required or not, should include a properly installed weather-resistive barrier (WRB). When adding continuous insulation, the WRB placement becomes code-critical: it must be on the warm side of the insulation to prevent condensation within the wall assembly. Common WRB options include housewrap (Tyvek, Henry Blueskin), fluid-applied membranes, and self-adhered membranes. The inspector will verify proper WRB lapping, taping, and integration with window and door flashings during the inspection.
What Continuous Insulation Actually Buys
Boise's climate makes a continuous layer over the studs worth having: the 1991–2020 normals at the airport put the average January low at 25.9°F and the average July high at 93.5°F, so the wall is working hard in both directions. What we will not do is attach a savings percentage to it.
Breaks thermal bridging
A continuous layer covers the studs, which is the part of the wall a cavity-only assembly cannot insulate. This is the mechanism; the size of the effect depends on the assembly you start from.
Warms the interior wall surface
The comfort change people actually notice is the end of cold spots on exterior walls in winter — a surface-temperature effect rather than a line on the utility bill.
Why we publish no percentage or payback
A heating-cost reduction figure depends on your existing wall, air leakage, fuel, and thermostat. The percentages that circulate in siding marketing are not measurements of Boise homes, and we are not going to repeat them. If you want a number, an energy audit on your own house will produce one.
No utility rebate covers this work: Idaho Power's residential incentives are its Heating and Cooling Efficiency Program (heat pumps, central air conditioners, duct sealing, smart thermostats, heat pump water heaters and similar equipment), the A/C Cool Credit, and the Shade Tree Project. Intermountain Gas rebates cover high-efficiency gas furnaces, boilers, and water heaters. Neither pays for siding, insulation, or air sealing, so the cost of this upgrade sits with the homeowner. The federal 25C energy-efficient home improvement credit is not an answer either: it ended for property placed in service after 31 December 2025.
Many Boise-area homes are in planned communities with covenants, conditions, and restrictions (CC&Rs) that regulate exterior appearance. If your home is in a homeowners association, the HOA approval process is separate from and in addition to any building permit requirements.
Common HOA Restrictions on Siding
Approved color palettes
Most HOAs in Eagle, Star, Meridian, and Southeast Boise maintain a list of pre-approved exterior colors. Some allow only earth tones and muted palettes. Choosing a color outside the approved list, even with the same siding material, typically requires a variance request.
Material restrictions
Many newer subdivisions prohibit vinyl siding and require fiber cement, engineered wood, stone veneer, or stucco. Some communities in Eagle and North Meridian mandate specific brands or profiles to maintain neighborhood uniformity.
Trim and accent requirements
CC&Rs may specify minimum trim widths, corner board styles, and contrasting accent colors. Some communities require window surrounds, belly bands, or water table trim as part of any siding replacement.
Percentage of material mix
Upscale communities may require a minimum percentage of stone or brick veneer on street-facing elevations, with siding limited to secondary elevations and rear walls.
Navigating the Approval Process
Request CC&R Documentation
Obtain your community's architectural guidelines, approved color list, and modification request form from the HOA management company before selecting materials.
Submit Material Samples
Most review boards require physical material samples (not just photos) and color swatches. Some require a 4-by-4-foot mockup panel installed on an inconspicuous wall for review.
Wait for Written Approval
The timeline is driven by the review board's meeting schedule — many meet monthly — so the question to ask is which meeting your application will reach. Never begin work before receiving written approval; a verbal approval is not enforceable.
Complete Work Within Deadline
HOA approvals usually carry an expiry date. Read it off your approval letter and coordinate it with your contractor's schedule so the work starts and finishes inside the window rather than requiring a resubmission.
Iron Crest Remodel tip: We assist with HOA submissions as part of our siding installation service. We prepare the required documentation, coordinate material samples, and track approval timelines so your project stays on schedule.
Boise's proximity to the foothills creates a Wildland-Urban Interface (WUI) zone where homes face elevated wildfire risk. If your property falls within a designated WUI zone, siding material selection is not just an aesthetic decision; it is a code requirement that affects life safety and insurability.
Non-Combustible Siding
Permit 428 requires siding in the hillside area or a Wildland Urban Interface area to be non-combustible — not merely fire-rated. A surface-burning class under ASTM E84 does not satisfy it. Materials that do:
- Fiber cement (James Hardie, Allura): non-combustible. The most common choice on Boise foothills homes.
- Metal siding (steel, aluminum): non-combustible panel. Available in modern profiles and traditional lap patterns.
- Stucco systems (traditional and EIFS): Non-combustible cladding when properly installed over non-combustible substrate.
- Brick and stone veneer: non-combustible. Often used as a primary or accent material on street-facing elevations.
Restricted or Prohibited
These materials are combustible and do not meet a non-combustible siding requirement:
- Wood siding: cedar carries a Class B flame-spread rating of 45 under ASTM E84 per the Western Red Cedar Lumber Association, but it is still a combustible wood product and a rating is not non-combustibility.
- Vinyl siding: combustible, and it softens and melts well below flame contact, exposing the sheathing behind it to radiant heat.
- Engineered wood: LP's Technical Bulletin No. 001 states that LP SmartSide is a Class C (III) product under ASTM E84, does not meet a Class A rating, and does not qualify as an ignition-resistant material under IWUIC Section 503.2.
Fire-retardant treated wood is sometimes offered as a way round this. It is still wood, a treatment changes surface burning rather than combustibility, and we are not going to tell you it satisfies a non-combustible requirement. That determination belongs to the Fire Code official, in writing, before material is ordered.
What Permit 428 Does Not Cover
The non-combustible requirement in Permit 428 is written about roof coverings and siding. It is worth being precise about that, because the rest of the envelope gets swept into it in a lot of online guidance:
- Vents, soffits, glazing, decking and railing: these are governed by other provisions and by the Fire Code official's determination for the property — not by the siding clause in Permit 428. We will tell you what the siding requirement is; we will not invent the rest.
- The assembly behind the panel: furring, rainscreen battens and the weather-resistive barrier do not become non-combustible because the cladding is. Where the siding is part of a rated or non-combustible assembly, the whole build-up has to be reviewed.
- Defensible space: a separate programme from the building permit. Coordinate it with the Fire Department rather than assuming the siding permit has settled it.
Boise WUI zone neighborhoods: North End foothills (above Hill Road and Harrison Boulevard), East End (above Warm Springs Avenue), areas near Table Rock and Castle Rock, Quail Ridge, Hillside Village, and portions of Southeast Boise near the Oregon Trail Reserve. The City maintains the official mapping, and whether a specific address falls inside it is a question for the City of Boise rather than for a contractor with a map. If you are unsure, ask the Building Division on (208) 608-7070, who will route the fire question to the right desk.
Boise's historic preservation overlay districts protect the architectural character of the city's oldest and most distinctive neighborhoods. If your home is within a designated historic district, any exterior alteration, including siding replacement, must receive approval from the Historic Preservation Commission before work begins.
Certificate of Appropriateness (COA)
The Certificate of Appropriateness is the regulatory approval required for exterior changes to properties within Boise's historic overlay districts, and the sequence matters: the COA comes before the building permit, not alongside it. The process evaluates proposed changes against the Secretary of the Interior's Standards for the Treatment of Historic Properties.
Application review (minor changes)
Like-for-like siding replacement with matching material and profile is generally reviewed as a staff-level decision rather than going to the Commission. This is the fastest path. Ask the Historic Preservation office for the current review time before you build a schedule around it.
Commission hearing (material changes)
Changing siding material type, profile, or configuration goes to a full Historic Preservation Commission hearing. The Commission meets on a published calendar, so the real constraint is which meeting your application makes — plan the submission around that rather than around a number of weeks.
Appeal process
If the Commission denies a COA application, the property owner can appeal to the Boise City Council. An appeal adds time and, in our experience, rarely succeeds without substantive design changes to the proposal.
Material Guidelines for Historic Homes
Wood clapboard and shingles
PreferredOriginal wood siding should be repaired rather than replaced when possible. When replacement is necessary, matching species, profile, exposure, and thickness is required.
Fiber cement (smooth finish)
Generally AcceptedSmooth-finish fiber cement that replicates the appearance of wood clapboard is generally accepted as a replacement material. Textured or wood-grain finishes may be rejected.
Vinyl siding
ProhibitedVinyl siding is prohibited in Boise's historic overlay districts. It does not replicate the appearance, shadow lines, or texture of historic wood siding.
Metal siding
Case by CaseMetal siding may be appropriate for specific architectural styles (mid-century modern, industrial) but is generally not permitted on Victorian, Craftsman, or Colonial homes.
Stucco over original siding
ProhibitedCovering original siding with stucco, EIFS, or any opaque coating is prohibited. Original siding character must be preserved or faithfully replicated.
Boise historic districts with siding restrictions: North End Historic District (Harrison Blvd to 28th Street, State Street to Hill Road), Warm Springs Historic District, East End (partial), and the Original Boise Townsite. Contact the Boise Planning Department's Historic Preservation office at (208) 608-7100 to confirm whether your property is within a designated district.
Siding removal on older Boise homes requires awareness of hazardous material regulations. Lead-based paint and asbestos-containing materials were commonly used in residential construction before federal restrictions were enacted. Disturbing these materials without proper precautions creates health hazards and regulatory violations.
Lead Paint (Pre-1978 Homes)
The EPA's Renovation, Repair, and Painting (RRP) rule applies to all renovation work that disturbs painted surfaces in homes built before 1978. Siding removal almost always disturbs painted surfaces, making RRP compliance mandatory for pre-1978 homes.
EPA-certified firm requirement
Any siding contractor performing RRP-triggering work on a pre-1978 home must be an EPA-certified Lead-Safe Firm. Verify any bidding contractor's firm status in the EPA's public Find a Certified Firm database at epa.gov before signing.
Certified renovator on-site
At least one EPA-certified renovator must be present on-site during all work that disturbs lead paint. This person directs containment setup and work practices.
Containment and dust control
Plastic sheeting must extend 10 feet from the work area on the ground. All windows and doors within 20 feet must be closed and sealed. HEPA-filtered power tools are required for sanding or scraping.
Waste disposal
Debris from lead paint removal must be collected in sealed, labeled containers and disposed of at an approved facility. Normal construction dumpsters cannot accept lead-contaminated waste.
Post-work verification
After siding removal is complete, the work area must pass a cleaning verification using EPA-approved procedures before the containment is removed.
Asbestos (Pre-1990 Homes)
Asbestos-containing materials (ACMs) were used in several exterior building products through the late 1980s. Siding removal on older homes may encounter these materials.
Cement-asbestos siding shingles
Common on homes built from the 1920s through the 1970s. These are rigid, brittle shingles that resemble thick slate, and the asbestos in them is bound in a cement matrix — which is why leaving them undisturbed is safer than breaking them up. Only a laboratory test tells you what a specific shingle contains.
Asbestos-containing caulk and glazing
Window and door caulking compounds on pre-1990 homes may contain asbestos. Disturbing old caulk during siding and trim removal can release fibers.
Testing requirement
Before disturbing any suspect materials, samples must be collected and tested by an accredited laboratory. Ask the laboratory for its current per-sample price and turnaround when you book the sampling; both are modest against the cost of an uncontrolled release.
Idaho DEQ notification
If asbestos-containing materials will be disturbed, the Idaho Department of Environmental Quality (DEQ) must be notified at least 10 working days before work begins. The notification form is filed online through the DEQ asbestos program.
Licensed abatement contractor
Asbestos removal must be performed by an Idaho DEQ-licensed asbestos abatement contractor, who is a separate trade from the siding contractor and is engaged separately. The cost scales with the quantity of material and the containment required, and it comes from the abatement contractor's own bid rather than from our estimate.
Boise's older neighborhoods: The North End, East End, Bench, Central Bench, and Downtown areas have the highest concentration of pre-1978 homes. If your home was built before 1978, assume lead paint is present on all painted exterior surfaces until testing proves otherwise.
When a siding installation project requires a permit, inspections are part of the process. The specific inspections depend on the scope of work and which code requirements are triggered. Understanding what inspectors look for helps avoid delays and re-inspection fees.
What Gets Inspected
Weather-Resistive Barrier (WRB)
The inspector verifies that the housewrap or other WRB is properly installed with correct lapping (upper courses overlapping lower courses), all seams taped, and proper integration with window and door flashings. This is the most common siding inspection.
Flashing Details
Head flashings above windows and doors, kick-out flashings at roof-to-wall intersections, and transition flashings between different materials or between the foundation and wall. Improper flashing is the leading cause of moisture intrusion behind siding.
Continuous Insulation(If applicable)
When rigid foam or mineral wool insulation is added beneath siding, the inspector verifies the insulation type, thickness, R-value (must match the permit application), proper installation without gaps, and correct fastener patterns.
Fire Blocking(If applicable)
For multi-story homes or homes with balloon-frame construction, fire blocking within the wall cavity must be verified at each floor level and at the top of the wall. This prevents fire from traveling vertically within the wall assembly.
Structural Sheathing(If applicable)
If sheathing was replaced, the inspector verifies the correct thickness (typically 7/16-inch OSB or 1/2-inch CDX plywood), proper nailing schedule (6 inches on edges, 12 inches in the field), and adequate attachment to wall framing.
Common Failure Points
WRB lapping reversed
The most common inspection failure. Housewrap must be installed so upper courses overlap lower courses (like shingles). Reversed lapping directs water behind the WRB instead of shedding it.
Missing kick-out flashings
Where a roof slope meets a sidewall, a kick-out flashing is required to direct water away from the wall and into the gutter. This small detail is frequently missed and is a top cause of concealed water damage.
Insulation gaps at corners and penetrations
Continuous insulation must be truly continuous. Gaps at corners, around windows, at utility penetrations, and at floor lines create thermal bridges and fail inspection.
Improper window flashing integration
Window flashings must integrate with the WRB in a specific sequence: sill pan first, then jamb flashing, then WRB, then head flashing. Incorrect sequencing traps water.
Nailing through continuous insulation without correct fasteners
When siding is installed over foam insulation, longer nails or screws are needed to penetrate through the insulation into the framing. Inspectors verify fastener embedment depth (minimum 1-1/4 inches into framing).
Scheduling Inspections
Inspections are requested through the jurisdiction's online portal, generally a day ahead, and are given a window rather than a time. The contractor must be present or available by phone. A failed inspection means corrections and a re-inspection request, which is the part that costs schedule — it is the main reason we would rather over-prepare a weather-barrier inspection than re-book one. Current notice periods and cut-off times come from the jurisdiction, so check them for your permit rather than working from a figure on a contractor's site.
Idaho registers contractors rather than licensing them, through the Division of Occupational and Professional Licenses. Working with a registered and insured contractor protects your investment and keeps the installation inside what the manufacturer's product warranty will recognise.
Idaho Contractor Requirements
Idaho contractor registration
Contractors must register with the Idaho Division of Occupational and Professional Licenses (DOPL). The registration number should appear on contracts, proposals, and advertising — ours is RCE-6681702. Verify any contractor's registration at dopl.idaho.gov.
General liability insurance
Registration requires proof of general liability coverage. Ask for the certificate and the limit rather than taking a figure from a website; for siding work this is what stands behind property damage during installation (broken windows, damaged landscaping) and completed-operations problems that surface after the job is done.
Workers' compensation insurance
Any contractor with employees must carry workers' compensation insurance. This protects you from liability if a worker is injured on your property. Request a current certificate of insurance before work begins.
EPA RRP certification (pre-1978 homes)
For work on homes built before 1978, the contractor must hold an EPA Renovation, Repair, and Painting (RRP) firm certification, and at least one certified renovator must be on-site during work that disturbs painted surfaces.
Manufacturer Warranties — And What We Do Not Hold
Iron Crest Remodel holds no manufacturer certification from James Hardie, LP, or any other siding manufacturer, and we are not going to imply one. What a manufacturer warranty covers is the product, and those terms belong to the manufacturer rather than to the installer. Here is what they say — confirm the current wording with the manufacturer for the product and colour you select.
James Hardie fiber cement
30-year non-prorated limited substrate warranty; ColorPlus finish 15 years
The ColorPlus finish warranty covers peeling, cracking and chipping — it is a finish warranty, not a fade warranty, and the distinction is the one homeowners are most often sold past. HZ5 is Hardie's cold-climate product line, engineered for freeze-thaw exposure, and Boise is in HZ5 territory.
LP SmartSide engineered wood
5/50 prorated limited warranty; ExpertFinish finish 15 years
The 5/50 is five years at 100 percent of labour and material, then material cost on a prorated basis through year 50 — not a one-year labour warranty. The SmartGuard zinc-borate process is formulated to resist termites and fungal decay; LP states plainly that it does not resist carpenter ants the same way.
How to verify credentials: ask any contractor for their Idaho registration number and a current certificate of insurance, verify the registration on the DOPL website, and call the insurance carrier directly to confirm the policy is active. Ours is RCE-6681702. Our own workmanship warranty is one year.
Common questions about permits and regulations for siding installation in the Boise area.
Do I need a permit to replace siding on my Boise home?
Yes. Inside Boise city limits, re-siding is permitted work: the City issues it under Permit 428, the Residential Roofing, Siding and Windows application, and that applies to a like-for-like replacement as much as to a change of material. A good deal of what circulates online about siding being permit-exempt is written for jurisdictions that are not this one. Scope drives what else comes with the permit — changing material type, adding continuous insulation beneath the new siding, replacing structural sheathing, cutting new wall penetrations, or working in a historic overlay district each add their own review and inspections. Confirm the scope for your address with the City of Boise Building Division at (208) 608-7070 before work starts; Planning & Zoning, on (208) 608-7100, handles the historic and zoning side.
Does adding insulation under new siding require a permit in Boise?
The permit is required either way in Boise, because re-siding itself goes through Permit 428. What adding continuous insulation changes is the review: it alters the wall assembly's thermal performance, which brings the project under the residential energy provisions Idaho has adopted alongside the 2018 International Residential Code and adds an insulation inspection to the schedule. The insulation is a genuine improvement to a Boise wall, particularly on an older house with no continuous layer over the studs. We do not publish a percentage for what it saves on the heating bill — that number depends on your existing assembly, your fuel and your thermostat, and the figures quoted around the trade are not measurements of anything.
What are the fire-rated siding requirements in Boise's foothills?
The requirement is non-combustible, which is a higher bar than fire-rated, and the difference matters. The City of Boise's Permit 428 application states that roof coverings and siding installed in the hillside area or in a Wildland Urban Interface area must be non-combustible as regulated by the City of Boise Fire Prevention Code. Fiber cement, metal, stucco, brick and stone veneer are non-combustible and clear it. Wood does not, and a Class A or Class B surface-burning classification does not convert a combustible material into a non-combustible one — this is the point at which most online guidance goes wrong. LP SmartSide does not clear it either: LP's own technical bulletin states that SmartSide is a Class C (III) product under ASTM E84, does not meet a Class A rating, and does not qualify as an ignition-resistant material under Section 503.2 of the International Wildland Urban Interface Code. Boise's hillside areas include the North End foothills, the East End above Warm Springs, and ground near Table Rock. The Fire Code official determines what is acceptable at your address; confirm the assembly before ordering material.
Can I change my siding color or material in a Boise HOA community?
Most planned communities in Eagle, Star, Meridian, and parts of Boise have architectural review boards that must approve exterior material and color changes before work begins. You will generally need to submit a written application with material samples, color swatches, and sometimes a mockup panel. The timeline is set by how often the board meets rather than by any published service standard, so ask your management company for the meeting calendar before you plan around it. Starting work before receiving written HOA approval can result in fines, required removal, or legal action.
Does my siding contractor need a license in Idaho?
Idaho registers contractors rather than licensing them, which is a distinction worth holding on to when you read a competitor's advertising. Registration is with the Idaho Division of Occupational and Professional Licenses (DOPL), and a registered contractor must carry general liability insurance and, where they have employees, workers' compensation. Ask for the registration number and a current certificate of insurance, and verify both — the registration on the DOPL website, the insurance by calling the carrier. Iron Crest Remodel is registered as RCE-6681702. One thing not to weigh: we hold no manufacturer certification from James Hardie, LP or anyone else, and neither do most contractors who imply otherwise. Manufacturer product warranties are the manufacturer's terms and apply to the product, not to the installer's badge.
What happens if old siding contains lead paint or asbestos?
For homes built before 1978, the EPA Renovation, Repair, and Painting (RRP) rule requires that siding removal be performed by an EPA-certified renovator using lead-safe work practices. This includes containment, HEPA vacuuming, and proper waste disposal. For older homes, asbestos may be present in certain siding products (cement-asbestos shingles) and caulking compounds. Idaho DEQ requires notification and licensed abatement if asbestos-containing materials will be disturbed. Testing is inexpensive relative to the cost of getting it wrong and should be done before demolition begins — the laboratory will quote the current per-sample price and turnaround.
