Siding Installation in Star, ID: Costs, Ideas & Options
From James Hardie fiber cement to LP SmartSide engineered wood — we handle material selection, weather barrier installation, and precision siding application from foundation to soffit.
Quick answer
Iron Crest Remodeling Group LLC provides siding installation in Star, ID. Most Star siding installation projects cost $10,000 – $36,000. Star siding costs reflect newer construction with fewer substrate surprises, but larger average home sizes (1,800–3,200 sq ft is typical) and the premium product specifications that Star's design-forward homeowner base tends toward.
Star is the Treasure Valley's newest suburban success story — a town of 15,000 that has tripled in population since 2010 as buyers discovered that Ada County's northwest corner offered new-construction housing at prices below Meridian and Boise while still within commuting distance of the valley's employment centers. With the overwhelming majority of Star's homes built after 2015, the housing stock is among the freshest in Idaho — but fresh construction does not mean problem-free siding, and Star's specific combination of exposed plain wind, high UV, and the personalization aspirations of homeowners who chose Star partly for its design flexibility creates a siding market that is uniquely oriented around aesthetics, quality upgrades, and smart long-term protection. Iron Crest Remodel serves Star homeowners who want to go beyond their builder's standard and invest in siding that reflects their vision for their home's exterior.
Protect your home and transform its curb appeal with professionally installed siding built for Idaho weather.

Siding is your home's first line of defense against wind, rain, snow, UV exposure, and temperature extremes — and in the Treasure Valley, those conditions are intense. Boise homes experience summer temperatures exceeding 100 degrees, winter lows well below freezing, rapid temperature swings of 40-50 degrees in a single day, and occasional wind-driven rain and hail. Professional siding installation includes removal of old siding, inspection and repair of the underlying sheathing and framing, installation of a code-compliant weather-resistive barrier (house wrap), proper window and door flashing, precision siding application with manufacturer-specified fastening and gapping, trim and corner finishing, and caulking. The three dominant siding materials in the Boise market — James Hardie fiber cement, LP SmartSide engineered wood, and vinyl — each offer distinct performance characteristics, aesthetics, and price points that should be matched to the homeowner's priorities.
Star homeowners pursue siding installation for a variety of reasons. Here are the most common situations we see:
- ✓Homeowners with failing, damaged, or deteriorated siding that no longer protects the home from weather
- ✓Anyone looking to upgrade from vinyl to fiber cement or engineered wood for improved durability and appearance
- ✓Homeowners who want to dramatically change their home's exterior look with new siding, trim, and color
- ✓Property owners dealing with moisture intrusion, rot, or pest damage behind existing siding
- ✓Homeowners building additions or making exterior modifications that require new siding to match or replace existing
Not every siding project is the same. Here are the most common project types we complete in Star:

James Hardie Fiber Cement Siding
Installation of HardiePlank lap siding, HardieShingle, or HardiePanel vertical siding. Fiber cement is non-combustible, rot-proof, termite-proof, and available in ColorPlus factory-finished colors with a 15-year color warranty.

LP SmartSide Engineered Wood Siding
Installation of LP SmartSide treated engineered wood siding in lap, panel, or shake profiles. Offers authentic wood grain texture, impact resistance, and a 5/50 year limited warranty. Lighter weight and easier to cut than fiber cement.

Vinyl Siding Installation
Installation of insulated or standard vinyl siding. The most budget-friendly option with zero painting maintenance. Modern vinyl comes in a wide range of styles and colors including board-and-batten and shake profiles.

Partial Siding Replacement
Replace siding on damaged sections, additions, or specific elevations while matching the existing siding profile and color. Includes weather barrier repair and flashing integration.

Siding and Trim Package
Complete siding replacement with coordinated trim — fascia, soffits, corner boards, window and door surrounds, and frieze boards. Creates a fully unified exterior appearance.

Star's housing stock is overwhelmingly post-2015 construction. Modern systems throughout, but builder-grade finishes that homeowners customize over time.
Pre-2010 (limited)
Star's small stock of pre-2010 townsite homes runs toward the higher end of the local range. Because these older homes may need both system and finish updates, budgets should account for more than cosmetic work alone.
2015–present (majority)
These newer homes — the majority in Star — need the least structural investment. Modern systems and open floor plans are already in place, so the budget concentrates on finish upgrades and outdoor living additions.
Common issues in Star homes
- •Builder-grade finishes that homeowners want to personalize
- •Standard builder landscaping and outdoor living that needs development
- •Limited storage in builder-designed kitchens
- •Basic builder lighting packages

Material selection affects the look, durability, and cost of your siding. Here are the most popular options we install in Star:

James Hardie HardiePlank Lap Siding
$10–$16 per sq ft installedThe gold standard in fiber cement siding. Made from cement, sand, and cellulose fibers. Non-combustible, rot-proof, termite-proof, and dimensionally stable. ColorPlus factory-applied finish provides superior color consistency and a 15-year color warranty.
Best for: Homeowners who want maximum durability, fire resistance, and long-term value

LP SmartSide Engineered Wood Siding
$8–$13 per sq ft installedTreated engineered wood siding with authentic wood grain texture. Made from wood strands bonded with resins and treated with SmartGuard process for moisture, fungal, and termite resistance. Lighter than fiber cement and easier to install.
Best for: Homeowners who want wood-grain appearance with engineered durability and lower cost than fiber cement

Vinyl Siding
$5–$10 per sq ft installedPVC-based siding that requires no painting, does not rot, and is immune to insect damage. Modern vinyl comes in many styles and colors with improved fade resistance. Insulated vinyl adds R-value and rigidity.
Best for: Budget-conscious projects, rental properties, and homeowners who want zero exterior painting maintenance

Weather-Resistive Barrier (House Wrap)
$0.50–$1.50 per sq ft installedTyvek, Henry Blueskin, or equivalent moisture barrier that wraps the exterior sheathing. Allows interior moisture to escape while blocking exterior water and wind. Critical component of a proper siding installation.
Best for: Required component beneath all siding installations for moisture and air management

PVC or Fiber Cement Trim
$4–$10 per linear foot installedRot-proof trim boards for window surrounds, corner boards, fascia, and decorative elements. PVC (Azek, Versatex) and fiber cement trim will not rot, warp, or require replacement due to moisture damage.
Best for: All exterior trim applications — especially in areas prone to moisture exposure

Here is how a typical siding project works from first contact to final walkthrough:
Exterior Assessment and Material Consultation
We inspect your existing siding, sheathing, flashing, and trim. We identify areas of damage, moisture intrusion, rot, and insulation deficiencies. We discuss material options, styles, and colors, and provide a detailed written estimate.
Material Selection and Design
You select your siding material (fiber cement, engineered wood, or vinyl), profile style, color, and trim details. We create an exterior design plan showing siding layout, trim placement, and color coordination with your roof, windows, and other fixed elements.
Permitting and Material Ordering
We pull any required building permits and order siding, trim, weather barrier, flashing, and fasteners. Lead times for factory-finished James Hardie products can run 4-8 weeks; LP SmartSide and vinyl are typically faster.
Old Siding Removal and Sheathing Inspection
Existing siding is carefully removed and disposed of. We inspect the underlying sheathing, framing, and insulation for damage, rot, pest activity, and moisture issues. Any damaged sheathing or framing is repaired before new siding goes on.
Weather Barrier and Flashing Installation
A code-compliant weather-resistive barrier (house wrap) is installed over the sheathing. All windows, doors, penetrations, and transitions receive proper flashing with manufacturer-approved materials and techniques to prevent water intrusion.
Siding and Trim Installation
Siding is installed from the bottom up with manufacturer-specified fastening, gapping, and overlap. Corner boards, window and door trim, frieze boards, and soffit panels are installed. All cuts, joints, and transitions are sealed and finished.
Caulking, Touch-Up, and Final Inspection
All joints, penetrations, and trim connections are caulked with premium exterior sealant. Touch-up paint is applied where needed. A final walkthrough verifies installation quality, flashing integrity, and overall appearance.
Here is what to expect for project duration when planning a siding in Star:
| Phase | Duration | Details |
|---|---|---|
| Assessment and Material Selection | 1–2 weeks | Exterior inspection, material consultation, color selection, and detailed estimate. Factory-finished color samples are available for review. |
| Material Ordering and Permitting | 2–6 weeks | Material ordering (factory-finished James Hardie can take 4-8 weeks), permit application and approval, and trade scheduling. |
| Old Siding Removal and Sheathing Repair | 2–5 days | Removal and disposal of existing siding, inspection and repair of sheathing and framing, and preparation for weather barrier installation. |
| Weather Barrier and Flashing | 1–2 days | House wrap installation, window and door flashing, and sealing of all penetrations and transitions. |
| Siding and Trim Installation | 5–12 days | Siding installation from foundation to soffit, trim and corner board installation, and detail finishing. Duration depends on home size, material, and architectural complexity. |
| Caulking, Touch-Up, and Inspection | 1–2 days | Final caulking, touch-up painting, cleanup, and walkthrough inspection with the homeowner. |
Star range: $10,000 – $36,000
Most Star projects: $20,000
Star siding costs reflect newer construction with fewer substrate surprises, but larger average home sizes (1,800–3,200 sq ft is typical) and the premium product specifications that Star's design-forward homeowner base tends toward. LP SmartSide maintenance and repaint runs $10,000–$15,000 on a typical Star home. Full James Hardie fiber cement upgrade with basic horizontal lap runs $18,000–$26,000. Mixed-profile upgrades — combining HardiePlank, HardiePanel board-and-batten, and HardieShingle accents — run $22,000–$36,000 and are among the most popular project types given Star's aesthetic personalization market. Substrate remediation adds minimal cost on Star's newer homes — typically $1,000–$3,000 for any wind-related flashing issues discovered during removal.
The final cost of your siding in Star depends on several factors. Here are the biggest cost drivers:
Siding Material Selection
high impactThe material choice is the largest cost variable. Vinyl is the least expensive at $5-10/sq ft installed, LP SmartSide is mid-range at $8-13/sq ft, and James Hardie fiber cement is the premium option at $10-16/sq ft installed.
Home Size and Exterior Surface Area
high impactThe total square footage of siding surface — determined by the home's footprint, number of stories, and architectural complexity — is the primary quantity driver. A two-story home has significantly more surface area than a single-story.
Old Siding Removal and Disposal
medium impactRemoving existing siding, especially multiple layers or materials with asbestos content in older homes, adds labor and disposal costs. Single-layer vinyl removal is fast; multi-layer or cement-asbestos removal is slower and more costly.
Sheathing and Framing Repair
medium impactDamaged or rotted sheathing and framing discovered after old siding removal must be repaired before new siding goes on. The extent of hidden damage is often unknown until the old siding comes off.
Trim and Detail Complexity
medium impactHomes with many windows, doors, corners, gables, and decorative trim elements require more cutting, fitting, and finish work. Simpler facades with fewer interruptions install faster and cost less.
Window and Door Flashing
low impactProper flashing around every window, door, and penetration is essential for preventing water intrusion. The number and size of openings directly affects flashing material and labor costs.
These are the real-world projects we see most often from Star homeowners:
Star Builder-Beige Liberation — Full Profile and Color Transformation
The defining siding project type in Star: replacing builder-standard LP SmartSide lap siding in a generic light tan or gray with a James Hardie mixed-profile exterior that reflects the homeowner's vision. These projects typically combine HardiePlank lap siding in a dark contemporary palette (Iron Gray, Cobblestone, Gauntlet Gray) on primary elevations with HardiePanel board-and-batten accents on gable ends, garage facades, or entry features. The transformation from a generic builder exterior to a personalized, design-forward home exterior is often dramatic — homeowners consistently report that the finished product feels like it finally matches what they imagined when they bought the home. These projects require HOA approval in most Star subdivisions but are receiving increasingly receptive responses as Star's design-review culture catches up with current market preferences.
Star Wind-Exposure Repair — Windward Elevation Flashing and Re-Side
Star's northwest Ada County position creates wind events on southwest and west elevations that have exposed installation quality deficiencies in some of the most rapidly built sections of Star's development. These projects address wind-related moisture infiltration at window heads and kickout flashing locations where builder-grade installation did not meet wind-resistant installation standards. The scope includes siding removal on affected elevations, installation of self-adhered flashing membrane at all openings, properly lapped and mechanically fastened housewrap, kickout flashing at all roof-to-wall intersections, and new siding installed to wind-rated fastening schedules. Material upgrade to fiber cement is recommended on these elevations given its superior wind-resistance characteristics.
Star Early-Phase Home — Pre-10-Year Maintenance and Upgrade Decision
Star homeowners with homes built between 2015 and 2019 are reaching a decision point: maintain the builder LP SmartSide with a repaint and joint maintenance scope, or upgrade to fiber cement now — taking advantage of the newer substrate condition, which means less remediation cost — before the LP SmartSide's first paint failure cycle requires attention. This is a proactive investment decision rather than a crisis response, and it requires an honest financial comparison. For homeowners who plan to stay in their Star home for 10-plus years, the proactive upgrade argument is often compelling. For those planning a sale within 3–5 years, the pre-sale repaint scope is typically the better financial decision.
The Lakes at Star — Elevated Specification for Premium Addresses
The Lakes at Star and similar premium pockets within the broader Star development market contain homes priced at or above Eagle's lower ranges. These homeowners have expectations that align more closely with Eagle's custom-home market than with Star's production-home core, and their siding projects reflect that: full fiber cement systems with mixed profiles, premium trim details, and dark contemporary color palettes that position these homes at the top of Star's visual hierarchy. The Lakes' proximity to the water features and open space that define the development makes exterior appearance especially important — these homes are visible from shared amenity areas and are photographed extensively in listing marketing. Iron Crest approaches The Lakes projects with the same design sophistication and installation precision that we bring to Eagle's custom-home market.

Problem: Moisture intrusion behind siding causing rot and mold
Solution: We remove old siding, repair damaged sheathing and framing, install a proper weather-resistive barrier with correct lapping and sealing, and flash all openings to create a watertight exterior shell.
Problem: Fading, warping, or cracking in old vinyl or wood siding
Solution: We replace failed siding with modern materials rated for Idaho's UV and temperature extremes. Fiber cement and engineered wood hold their color and shape far longer than older vinyl or untreated wood.
Problem: Gaps and failed caulking allowing air and water infiltration
Solution: We install siding with manufacturer-specified gapping, use backer rod and premium caulk at all joints and penetrations, and ensure every seam and transition is properly sealed.
Problem: Woodpecker damage or pest intrusion in wood or foam-backed siding
Solution: We replace damaged sections and install fiber cement or other pest-resistant materials. James Hardie siding is immune to woodpecker damage, termites, and rot.
Problem: No weather barrier or inadequate flashing under existing siding
Solution: Many older Treasure Valley homes have siding installed directly over sheathing without house wrap or proper flashing. Our complete re-side includes a full weather barrier and flashing system as a standard component.

Star shares the Treasure Valley climate. Open terrain and rural-edge location mean more wind and UV exposure.
Wind and Open Exposure
Higher wind loads and more UV exposure than sheltered locations. Durable exterior materials are important.
New Construction Settling
Homes 3-7 years old may show minor settling cracks in drywall — cosmetic and common in new construction on Treasure Valley soils.
Downtown Star
The original town center with a mix of older homes and newer infill. Some properties date back several decades and offer full renovation potential.
Common projects in Downtown Star:
- •Full home renovations
- •Kitchen and bathroom remodels
- •Home additions
- •ADU construction on larger lots
The Lakes at Pristine Springs / Newer Subdivisions
Post-2015 master-planned communities with modern homes. Builder-grade finishes are the primary upgrade target.
Common projects in The Lakes at Pristine Springs / Newer Subdivisions:
- •Kitchen upgrades with better cabinets and countertops
- •Bathroom finish updates
- •Flooring replacement
- •Outdoor living — decks, patios, pergolas
Every Star neighborhood has different housing stock, homeowner priorities, and project considerations. Here is what siding looks like in each area:

Helpful ID resources
- Idaho DEQ — Asbestos Program — testing and abatement requirements for pre-1980 homes
- EPA Lead Renovation, Repair and Painting (RRP) Program — required certification for work in pre-1978 homes
- ●Siding profile selection — lap (horizontal), board-and-batten (vertical), shake (shingle-style), and panel each create a different architectural character
- ●Mixed materials — combining two siding profiles (e.g., lap siding on main walls with board-and-batten on gable accents) adds visual depth and architectural interest
- ●Color coordination — choose siding color to complement your roof, stone or brick elements, and front door; test large samples on the house in natural light
- ●Trim proportions — wider trim boards around windows and doors create a more substantial, custom look; standard narrow trim is more economical but less distinctive
- ●Reveal and exposure — the amount of siding visible between horizontal rows (the reveal or exposure) affects shadow lines and overall appearance
- ●Regional style — Boise neighborhoods range from modern farmhouse to craftsman to contemporary; your siding choice should complement your home's architecture and neighborhood context
Here are the design trends we see most often in Star siding projects:
- →Modern farmhouse and transitional aesthetics
- →Personalizing builder-grade homes with premium finishes
- →Large kitchen islands with seating
- →Outdoor living — large decks, covered patios, fire pits
- →LVP flooring and modern tile selections
Star's rapid growth and desirable small-town character make updated homes highly sought after. Finish upgrades in Star homes provide strong returns in a competitive resale market. The community continues to attract buyers willing to pay a premium for updated, personalized homes.
Costs and permit requirements differ by jurisdiction across the Treasure Valley. These guides cover Star specifically.
Avoid these common pitfalls Star homeowners encounter with siding projects:
Mistake: Choosing a color palette without researching how it looks on large wall surfaces in Star's light
Better approach: Star's high-altitude semi-arid sunlight is more intense than coastal or inland-lower-elevation markets, and color perception at large scale in direct afternoon sun differs significantly from chip-sample evaluation indoors. Before committing to a dark palette — which is the most popular choice in Star's design-forward market — request a large-format sample board from the manufacturer and evaluate it at your property at multiple times of day. Better yet, identify a completed Star installation in the same color and evaluate it in person. Most Hardie ColorPlus colors are formulated for western high-UV environments, but the evaluation step prevents the disappointment of a color that looks dramatic on a chip and flat at scale.
Mistake: Delaying HOA submittal until after material orders are placed
Better approach: In Star's HOA-governed communities, HOA submittal and material ordering can run concurrently — but submitting after contract signing and before material ordering is the wrong sequence. Prepare and submit the HOA package simultaneously with signing the contract, and condition the material order on HOA approval. This way, approval arrives around the same time as material delivery, keeping the project schedule tight. HOA revisions requested during review can be addressed before materials are produced, avoiding the cost and delay of changing a Hardie ColorPlus color order after production begins.
Mistake: Treating wind-zone installation details as optional on Star's windward elevations
Better approach: The wind-resistant installation details for Star's southwest and west-facing walls — proper nailing schedules, mechanically fastened housewrap, kickout flashing integration — are not optional upgrades in Star's wind environment. They are the difference between a siding installation that performs for 30 years and one that shows fastener creep, joint opening, and moisture infiltration at the 10-to-15-year mark. Ask your contractor for specific wind-zone installation documentation for Star-area projects before signing — a contractor with genuine Star experience will have these details as standard practice, not as a line-item addition.
Mistake: Installing board-and-batten profiles in locations where they will accumulate wind-driven debris
Better approach: Board-and-batten siding has vertical channels between the narrow battens and the broader board behind them. On windward elevations in Star's wind environment, these channels can funnel wind-driven debris and moisture into accumulation points. Reserve board-and-batten for gable peaks, sheltered accent walls, and entry features — locations that see limited direct wind load — rather than using it as the primary cladding on windward west and south wall areas. On those elevations, smooth-profile lap siding provides better cleanability and wind resistance.
Mistake: Underestimating how significantly a siding transformation changes resale positioning
Better approach: In Star's builder-uniform neighborhoods, the listing photography for a home with a distinctive, professionally executed exterior upgrade looks dramatically different from its neighbors — and that difference is real and measurable in buyer inquiry rates, days on market, and final sale price. If you are planning a siding upgrade partly in advance of a sale, document the work thoroughly — manufacturer warranty documentation, HOA approval records, before-and-after photography — and communicate the upgrade prominently in listing materials. A James Hardie fiber cement installation with a 30-year substrate warranty and a 15-year ColorPlus finish warranty is a genuine and specific selling point in Ada County's informed buyer market.

Can I change my Star home's siding profile if I'm in an HOA?
Profile changes — adding board-and-batten on gable ends, changing from horizontal lap to mixed profiles — require HOA design review committee approval in Star's planned communities. However, these changes are approved with increasing frequency as Star's HOA communities update their design guidelines to reflect current market preferences. The key to approval is a complete, professionally prepared submittal that demonstrates how the proposed profile change is consistent with the neighborhood's architectural character and quality standards. Iron Crest prepares full HOA submittal packages for every Star project involving profile changes, including elevation drawings, manufacturer material specifications, and color samples evaluated in the community's specific light environment. Our submittal quality significantly improves first-review approval rates.
My Star home is only 7 years old. Is it too early to think about siding replacement?
Not at all — and the timing is actually advantageous for certain upgrade decisions. Homes built between 2015 and 2019 are approaching the first significant decision point for LP SmartSide maintenance (the 7-to-10-year repaint window). Upgrading to James Hardie fiber cement now — while the substrate is in excellent condition — minimizes remediation scope and cost while locking in a 15-year ColorPlus finish warranty and a 30-year substrate warranty. If you are planning to stay in your Star home for 10-plus years, upgrading now rather than maintaining through one or two paint cycles is often the better financial decision. If your horizon is 3–5 years to a sale, the pre-sale repaint and maintenance scope delivers better return for the shorter holding period.
How does wind in Star affect siding installation quality?
Star's northwest Ada County position exposes west and southwest-facing walls to persistent wind events that stress siding installations more than in sheltered Treasure Valley locations. The installation details that matter most in Star's wind environment are: proper nailing schedules into solid framing at maximum 16-inch on-center spacing, housewrap mechanically fastened rather than relying solely on tape-and-overlap at vertical seams, kickout flashing that integrates properly at all roof-to-wall intersections, and joint sealant selection rated for the thermal movement range that Star's temperature differential creates. Ask your contractor specifically about their wind-zone installation practices for Star — contractors with Star project experience have refined these details through real-world performance.
What's the best way to make my Star home look different from all the other builder homes in my neighborhood?
The most effective exterior differentiation for Star's production-home neighborhoods is the combination of a dark, saturated color palette with mixed siding profiles. Replacing builder-standard light tan LP SmartSide with James Hardie HardiePlank in Iron Gray or Gauntlet Gray on primary walls, plus board-and-batten HardiePanel on gable peaks and possibly the garage facade, creates a visual identity that is dramatically distinct from builder-standard neighbors while remaining cohesive with the neighborhood's architectural character. The profile change from uniform horizontal lap to a mixed-profile exterior creates depth and shadow lines that make the home's facade read as more architecturally sophisticated in both direct view and listing photography. This combination — dark palette plus mixed profiles — is the signature project type in Star's market and consistently produces the highest homeowner satisfaction of any siding upgrade we execute.
How long does a full siding upgrade take on a Star home?
A full siding replacement on a typical Star home (2,000–2,800 sq ft, two stories) takes 2–4 weeks of active construction time, including removal, substrate inspection, housewrap installation, new siding installation, trim work, caulking, and cleanup. HOA approval — required before construction begins in most Star communities — runs 2–4 weeks for complete submittals, and material lead time for James Hardie ColorPlus products runs 3–5 weeks from order. The practical timeline from first consultation to project completion is 6–10 weeks, and planning for this lead time from the beginning avoids schedule compression later. We recommend initiating the project conversation in late winter or early spring if a summer installation is desired.
What is the best siding material for homes in Boise?
James Hardie fiber cement siding is the top choice for durability, fire resistance, and long-term value in the Boise climate. LP SmartSide offers similar performance at a lower cost with a more wood-like texture. Vinyl is the most budget-friendly but offers less impact resistance and aesthetic quality.
How long does new siding last?
James Hardie fiber cement siding lasts 40-50+ years. LP SmartSide engineered wood lasts 30-40 years. Quality vinyl siding lasts 20-30 years. Factory-applied color finishes on fiber cement and engineered wood extend the interval between repainting.
Does siding replacement require a permit?
In most Treasure Valley jurisdictions, full siding replacement requires a building permit — especially if the project involves sheathing repair or weather barrier installation. We handle all permit applications and inspections.
How much does siding replacement cost in Boise?
Full siding replacement for a typical single-story home in the Boise area runs $12,000-25,000 for vinyl, $18,000-35,000 for LP SmartSide, and $22,000-45,000+ for James Hardie fiber cement. Costs depend on home size, material, trim scope, and repair needs.
Can you install new siding over existing siding?
In some cases, new siding can be installed over existing siding — but we generally recommend removing old siding so we can inspect and repair the sheathing, install a proper weather barrier, and ensure a flat, secure substrate for the new material.
How long does siding installation take?
A typical full re-side of a single-story home takes 2-3 weeks of on-site work. Two-story homes and complex projects take 3-4 weeks. Material lead times (especially factory-finished colors) add 2-6 weeks before construction starts.
Is James Hardie siding worth the extra cost?
For most Boise homeowners, yes. Hardie siding offers superior fire resistance, impact resistance, color retention, and lifespan compared to alternatives. The higher upfront cost is offset by lower maintenance, fewer repairs, and longer intervals between repainting.
