From outdated floor plans to modern open-concept living — we coordinate every trade, every finish, and every detail across your entire home renovation.
Whole-home remodeling in New Plymouth, Idaho is, at its core, the rehabilitation of a planned colony town's housing stock. New Plymouth was platted in 1896 by the Plymouth Society of Chicago and irrigation pioneer William E. Smythe — a horseshoe of two streets wrapped around a mile-long Boulevard park, the open end pointing toward the Payette River and the railroad, the colony divided into acre tracts for house, garden, and pasture. The homes that grew from that vision — colony-era farmhouses, a deep layer of 1950s–1970s ranches built as irrigated agriculture matured, and a modest minority of post-2000 builds — are now the subject of comprehensive renovations because their bones are sound and their systems are not. With a 2020 Census population of 1,494 in a multi-generational agricultural community at roughly 2,257 feet elevation, a New Plymouth whole-home remodel is rarely a flip; it is a family bringing a home it intends to keep for decades up to a standard it can live with for the next generation. Iron Crest Remodel (Iron Crest Remodeling Group LLC, Idaho RCE-6681702) treats these as the systems-first projects they are: in a 1915 Boulevard farmhouse, the electrical service, plumbing, insulation, and structure must be addressed before a single finish decision matters, and pretending otherwise is how whole-home budgets collapse.
Reimagine your entire home with a unified remodeling plan built for how you actually live.
A whole-home remodel addresses every major system and finish in your house under a single project scope — framing and layout changes, electrical panel and circuit upgrades, plumbing updates, HVAC improvements, insulation, drywall, flooring, trim, paint, and fixture installation across every room. In the Treasure Valley, many homes built in the 1980s and 1990s have compartmentalized floor plans, outdated electrical systems, builder-grade finishes, and inefficient insulation that no longer meet modern standards for comfort, energy efficiency, or livability. A well-planned whole-home renovation transforms these properties into cohesive, modern spaces while addressing deferred maintenance and code compliance in a single mobilization. The key advantage of a whole-home approach is coordination — trades move efficiently through the house in sequence, finishes are consistent from room to room, and the homeowner avoids years of disruptive room-by-room projects.
New Plymouth homeowners pursue whole-home remodeling for a variety of reasons. Here are the most common situations we see:
Not every whole-home remodel project is the same. Here are the most common project types we complete in New Plymouth:
Full gut and rebuild of every interior space including kitchen, bathrooms, bedrooms, and living areas. New flooring, drywall, trim, paint, lighting, and fixtures throughout. Layout changes and wall removals as needed.
Remove interior walls between kitchen, dining, and living areas to create a modern open floor plan. Includes structural header installation, electrical and HVAC rerouting, flooring transitions, and finish work.
Reconfigure the main floor to include a primary bedroom suite, accessible bathroom, and laundry — allowing single-level living without using stairs. Ideal for aging-in-place planning.
Comprehensive renovation of a recently purchased home that needs everything — updated electrical, new plumbing, insulation, drywall repair, flooring, kitchen, bathrooms, and cosmetic finishes throughout.
A planned multi-phase renovation that addresses the entire home over two or three stages, allowing homeowners to remain in the home during construction by completing one zone at a time.
New Plymouth's housing is older and more layered than the suburban Treasure Valley: a 1896 colony-era and pre-1940 farmhouse core, a deep 1950s–1970s ranch layer, and a modest post-2000 subdivision minority. Most homes sit over vented crawlspaces.
Original colony and early-twentieth-century farmhouses around The Boulevard. Plaster-and-lath interiors, original wood siding and single-pane sash, galvanized supply lines, undersized electrical service, and crawlspace subfloors. Pre-1978 lead-paint and pre-1980 asbestos handling required.
Ranches and ramblers built as irrigated agriculture matured. Sound framing, aging copper plumbing, marginal panels, single-pane or early aluminum windows, thin insulation, and closed floor plans. Pre-1978/1980 environmental rules still apply.
Post-2000 builds such as Harvest Creek. Modern PEX plumbing, adequate electrical, and builder-grade finishes on tighter lots. No environmental-testing requirements.
Material selection affects the look, durability, and cost of your whole-home remodel. Here are the most popular options we install in New Plymouth:
The most popular whole-home flooring choice in the Treasure Valley. LVP is waterproof, scratch-resistant, available in realistic wood-look patterns, and installs quickly over existing subfloors. It provides a consistent look from room to room.
Best for: Main living areas, hallways, bedrooms, and kitchens
A premium flooring option that provides real wood appearance and feel with better dimensional stability than solid hardwood. Available in oak, hickory, maple, and walnut species with various stain options.
Best for: Living rooms, dining rooms, and bedrooms in climate-controlled environments
Engineered quartz is the go-to countertop surface for kitchen and bathroom renovations. Non-porous, stain-resistant, and available in hundreds of colors and patterns. Consistent appearance across multiple rooms.
Best for: Kitchen countertops, bathroom vanities, and laundry surfaces
Semi-custom cabinets offer the best balance of quality, options, and value for whole-home projects. More door styles, finishes, and sizing flexibility than stock cabinets, with 4-8 week lead times.
Best for: Kitchen, bathroom, laundry, and built-in storage throughout the home
High-quality interior paints from brands like Benjamin Moore, Sherwin-Williams, or PPG provide better coverage, durability, and washability than builder-grade paint. Consistent sheen and color throughout the home.
Best for: Every wall and ceiling surface in the home
Here is how a typical whole-home remodel project works from first contact to final walkthrough:
We walk every room with you, documenting what works and what does not. We discuss your vision for layout, flow, finishes, and function — then establish a realistic budget range and phasing strategy if needed. You receive a preliminary scope and conceptual plan within one to two weeks.
We develop a comprehensive design plan covering layout changes, flooring selections, cabinet and countertop choices, paint colors, lighting plans, fixture selections, and hardware finishes for every room. Consistency across the home is a primary focus at this stage.
We pull all required permits through Ada County or Canyon County — structural, electrical, plumbing, and mechanical as needed. We schedule and sequence every trade so work flows efficiently from demolition through finish.
Controlled demolition begins zone by zone. Wall removals, structural headers, framing modifications, subfloor repairs, and any foundation or crawlspace work are completed first. Rough inspections are scheduled before closing walls.
All wiring, plumbing lines, HVAC ductwork, and insulation are installed or updated throughout the home. Panel upgrades, new circuits for kitchens and bathrooms, and updated supply and drain lines are completed during this phase.
Drywall, tape, and texture are completed. Flooring is installed throughout, followed by trim, doors, cabinetry, countertops, tile, fixtures, lighting, and hardware. Paint is applied after trim and before final fixture installation.
We complete all final inspections, address every punch list item, test all systems and fixtures, and conduct a thorough room-by-room walkthrough with you to confirm everything meets the agreed-upon scope and quality standards.
Here is what to expect for project duration when planning a whole-home remodel in New Plymouth:
| Phase | Duration | Details |
|---|---|---|
| Planning and Design | 4–8 weeks | Comprehensive home assessment, design development, material selections, trade scheduling, and contract finalization. Larger homes with more complex scopes require longer planning. |
| Permitting | 2–4 weeks | Permit applications for structural, electrical, plumbing, and mechanical work through Ada County or Canyon County. Multiple permits may be required for whole-home projects. |
| Demolition and Structural Work | 1–3 weeks | Controlled demolition, wall removals, structural modifications, subfloor repair, and framing. Scope depends on how much of the existing structure is being modified. |
| Systems Rough-In | 2–4 weeks | Electrical rewiring, plumbing rough-in, HVAC modifications, and insulation installation throughout the home. Rough inspections are scheduled before closing walls. |
| Finish Work | 4–8 weeks | Drywall, flooring, trim, cabinetry, countertops, tile, paint, fixtures, and hardware installation across every room. This is the longest active construction phase. |
| Final Inspections and Walkthrough | 1–2 weeks | Punch list completion, final inspections, systems testing, and room-by-room walkthrough with the homeowner. |
New Plymouth range: $90,000–$180,000 – $450,000–$900,000
Most New Plymouth projects: $220,000–$450,000
New Plymouth whole-home costs are dominated by the age and condition of the existing home and the extent of systems modernization, not by local labor rates. The low range covers a comprehensive cosmetic and light-systems renovation of a newer or already-updated home — finishes throughout, kitchen and baths, flooring, paint, with mostly sound existing systems. The high range covers full down-to-studs renovations of large colony-era or substantial rural homes: complete electrical, plumbing, HVAC, insulation, and window replacement; structural reconfiguration; custom kitchen and baths; and high-end finishes throughout. The average band reflects the typical New Plymouth whole-home project: a mid-century ranch or moderate colony home taken to a comprehensive renovation — service-panel upgrade, plumbing modernization, insulation and windows, HVAC, opened floor plan, new kitchen and baths, flooring and finishes throughout. The decisive cost drivers are local and structural: undersized electrical service requiring a full upgrade, galvanized plumbing requiring whole-house replacement, EPA RRP lead-safe and asbestos handling on pre-1980 stock, frost-line and snow-load structural work where the layout changes, and septic-capacity questions on rural parcels when bedrooms are reconfigured or added. We build a substantial discovery contingency into pre-1980 whole-home estimates because opening every wall in a century-old colony home reliably reveals conditions that must be corrected to code.
The final cost of your whole-home remodel in New Plymouth depends on several factors. Here are the biggest cost drivers:
The size of the home and the number of rooms being renovated is the primary cost driver. A 1,500 sq ft home costs significantly less than a 3,000 sq ft home with the same scope of work per room.
Removing load-bearing walls, adding structural headers, modifying the floor plan, or opening up rooms requires engineering, permits, and additional framing labor that adds significant cost.
Kitchens and bathrooms are the most expensive rooms to renovate per square foot due to cabinetry, countertops, plumbing, tile, and specialized labor. The number and scope of kitchen and bath renovations heavily influences total project cost.
Older homes may need panel upgrades, rewiring, new circuits, updated plumbing supply lines, or drain modifications. These system-level updates add cost but are essential for safety and code compliance.
The gap between builder-grade and mid-range finishes can add 30-50% to material costs. Premium flooring, quartz countertops, semi-custom cabinets, and quality fixtures all contribute to the overall finish budget.
If the project is large enough to require temporary relocation, housing costs add to the overall budget. Phased projects that allow you to live in part of the home during construction may take longer but avoid relocation costs.
These are the real-world projects we see most often from New Plymouth homeowners:
The signature New Plymouth whole-home project: a pre-1940 Boulevard farmhouse with sound structure but century-old systems. Scope is comprehensive — full rewire with a service-panel upgrade, complete repipe from galvanized to PEX or copper, insulation and air-sealing to the 2018 IECC, full window replacement, HVAC modernization, structural reconfiguration to open the compartmentalized plan, new kitchen and baths, and finishes throughout, all executed with EPA RRP lead-safe practices and asbestos handling. The design imperative is preserving the home's period character — the very thing that makes these homes worth saving — while delivering modern performance. These are the most complex and rewarding projects in town.
New Plymouth's 1950s–1970s ranches are the most common whole-home candidates: solid framing, predictable footprints, but aging copper, marginal panels, original single-pane windows, thin insulation, and closed floor plans. Scope typically includes a service upgrade, targeted repipe and rewire, full insulation and window replacement, HVAC modernization, removal of soffits and bearing-wall reconfiguration to open the plan, a new kitchen and baths, and flooring and finishes throughout. These homes deliver an exceptional transformation per dollar because the structure cooperates.
On the farm acreage, larger homes are renovated to serve multiple generations under one roof — reworking the plan for a primary suite plus separate-feel quarters or a junior ADU, accessible features for aging parents, and expanded shared living space. Whole-home scope here integrates systems modernization with significant structural reconfiguration and addresses the rural-utility realities: well water treatment, septic capacity for any added or relocated bedrooms under Payette County and DEQ rules, and county permitting since these parcels are typically outside city limits.
Post-2000 Harvest Creek and similar homes have modern systems but builder-grade finishes and dated layouts throughout. A whole-home refresh here skips the systems rehabilitation and focuses on comprehensive finish replacement — kitchen, all baths, flooring, trim, lighting, paint, and selective layout improvements — delivering a cohesive, current home without the cost and disruption of systems work. Predictable scope, no environmental testing on post-1985 construction.
Many New Plymouth families need to remain in the home during renovation. We structure phased whole-home projects — sequencing systems work and room renovations so the household retains a functional kitchen and bath at each stage — which extends the timeline but avoids the cost and dislocation of relocating. This phasing discipline is particularly valuable for multi-generational households and for rural properties where temporary relocation is impractical.
Solution: We remove or modify interior walls to create open-concept living areas, install structural headers where needed, and unify flooring and finishes across the connected spaces.
Solution: A whole-home remodel ensures consistent flooring, trim profiles, paint colors, door hardware, and fixture finishes throughout — eliminating the patchwork look of decades of small projects.
Solution: We upgrade the electrical panel, add dedicated circuits for kitchens and bathrooms, install GFCI and AFCI protection where required by code, and add outlets and lighting throughout the home.
Solution: During the renovation, we upgrade insulation in walls, attics, and crawlspaces — improving comfort and reducing heating and cooling costs in Boise's hot summers and cold winters.
Solution: A whole-home renovation exposes framing, plumbing, and wiring that may have been hidden for decades. We identify and repair water damage, pest damage, improper wiring, and failing plumbing during the demolition phase.
High-desert Payette River valley at ~2,257 ft: hot, dry, sun-intense summers and cold winters with real snow load and a 24-inch frost line, plus wind off open agricultural ground and hard water.
Payette County design criterion of 30 psf governs roof and deck structural design.
24-inch frost depth requires foundations, footings, and deck piers below grade to prevent frost heave.
115 mph ultimate wind speed and Seismic Design Category C; wind off open farmland drives infiltration and uplift on exposed structures.
Open-valley sun degrades wood siding, coatings, and decking; wide hot-to-cold swing drives material movement and air leakage.
Hard municipal and private-well water scales glass and fixtures and degrades grout and stone; drives material/glass selection.
The 1896 colony heart: two horseshoe streets around the mile-long Boulevard park with original irrigation ditches. Predominantly colony-era and pre-1940 wood-sided farmhouses on generous original acre tracts; strong period character and a protected streetscape.
Common projects in The Boulevard / Historic Horseshoe Core:
Grid streets around and behind the horseshoe filled with 1950s–1970s ranches and ramblers built as the irrigated farm economy matured. Sound framing, aging copper and marginal panels, closed floor plans, on municipal water and sewer.
Common projects in Mid-Century Ranch Streets (In-Town):
Working farm and ranch acreage surrounding the town, outside city limits and under Payette County jurisdiction. Homes range from century-old farmsteads to modern custom builds, typically on private wells and septic systems.
Common projects in Agricultural Fringe / Rural Acreage:
Post-2000 subdivision pockets representing New Plymouth's modern housing minority. Modern PEX plumbing, adequate panels, and builder-grade finishes on tighter lots; no environmental-testing requirements.
Common projects in Harvest Creek / Newer Subdivisions:
Every New Plymouth neighborhood has different housing stock, homeowner priorities, and project considerations. Here is what whole-home remodel looks like in each area:
Permit authority: City of New Plymouth (building inspection contracted to the City of Fruitland Building Department) for properties inside city limits; Payette County Building Department for unincorporated rural parcels. Plumbing and electrical permits issued separately by the State of Idaho (Division of Building Safety / DOPL).

Here are the design trends we see most often in New Plymouth whole-home remodel projects:
New Plymouth and Payette County home values have appreciated well above their historic norms; local market median list prices reached roughly $485,000 with an average around $449,000 in early 2026 (Redfin), against a longer-run median home value near $277,500. Inventory is limited in a small market with homes selling in roughly 70 days. With trading up locally often impractical, long-tenure, multi-generational families predominantly renovate to keep — making durable, do-it-once work the local standard and a strong resale signal in a closely-watched market.
Avoid these common pitfalls New Plymouth homeowners encounter with whole-home remodel projects:
Better approach: In colony-era and many mid-century New Plymouth homes, the electrical service, plumbing, insulation, and windows all need replacement. Doing rooms individually repeatedly opens and closes walls around obsolete systems. A whole-home, systems-first sequence replaces them once with walls open — more economical and more durable than piecemeal work.
Better approach: Opening every wall in a century-old colony home reliably reveals conditions — failed wiring, galvanized pipe, hidden rot, asbestos materials — that must be corrected to code. A substantial discovery contingency is honest budgeting for pre-1980 New Plymouth whole-home work, not padding. Fixed quotes without it lead to either skipped problems or change-order conflict.
Better approach: On pre-1978 stock, EPA RRP lead-safe practices and asbestos handling apply across the entire project. Establish project-wide containment and protocols at the outset rather than reacting room by room. This is a legal requirement and a defining feature of comprehensive New Plymouth renovation.
Better approach: On the agricultural fringe, changing or adding bedroom count alters the septic design load under Payette County and DEQ rules. Evaluate septic capacity whenever a whole-home reconfiguration touches bedroom count — a shortfall discovered late can force redesign or major unbudgeted cost.
Better approach: A colony-era Boulevard farmhouse is worth comprehensively renovating precisely because of its character. Modernize systems and performance while preserving the proportions, trim, and detailing that define it. A character home gutted into a generic interior loses the value and appeal that justified the investment in this market.
Colony-era farmhouses and many mid-century New Plymouth ranches still run on undersized electrical service, galvanized or failing plumbing, minimal insulation, and single-pane windows. Updating one room at a time means repeatedly opening and closing walls around systems that should have been replaced — expensive and wasteful. A whole-home approach replaces the service panel, plumbing, insulation, windows, and HVAC once, with walls open, in proper sequence, then finishes over sound systems. In this housing stock, systems-first is both more economical and more durable than piecemeal updates.
Inside city limits, the building permit application routes through New Plymouth City Hall with inspections by the contracted City of Fruitland Building Department (208-452-4946); rural parcels outside city limits are permitted by Payette County. In addition to the building permit, a comprehensive renovation requires separate State of Idaho plumbing and electrical permits — central to whole-home work because of the full rewire and repipe involved. We confirm jurisdiction and coordinate the complete permit set.
Often yes, through a phased approach. We sequence systems work and room renovations so the household keeps a functional kitchen and bath at each stage. Phasing extends the overall timeline but avoids the cost and dislocation of relocating — particularly valuable for multi-generational households and rural properties where temporary housing is impractical. We design the phasing plan around your household's needs at the outset.
Yes. For pre-1978 homes — most of the Boulevard core and many ranches — EPA RRP lead-safe practices apply across every area disturbed, and pre-1980 homes commonly contain asbestos in flooring and mastic that requires testing and licensed handling. In a whole-home project this is a project-wide protocol, not a room-by-room afterthought. We manage environmental testing and compliant work practices as standard on all pre-1980 New Plymouth renovations.
A comprehensive finish refresh of a newer home runs 14–22 weeks. A comprehensive mid-century ranch renovation runs 20–32 weeks. A down-to-studs colony-era farmhouse renovation runs 26–44 weeks. A phased renovation of an occupied home runs 30–50 weeks. Add permit processing through the applicable authority plus separate state trades permits, and septic evaluation time for rural parcels. We build a realistic schedule with discovery contingency for pre-1980 homes rather than an optimistic one that ignores guaranteed surprises.
In this market, usually yes. New Plymouth and Payette County values are well above historic norms with limited inventory, so a better home in the same community is often unavailable at any reasonable price. Comprehensively renovating a structurally sound colony farmhouse or ranch keeps a long-tenure, multi-generational family rooted on land it intends to hold for decades, and a thoroughly renovated character home is among the most valued in this small market. For most New Plymouth families, renovating to keep is the rational choice.
A typical whole-home remodel takes 3 to 6 months of active construction, depending on the size of the home and scope of work. Including planning, design, permitting, and material lead times, the total project timeline is usually 5 to 9 months from first meeting to final walkthrough.
It depends on the scope. Some projects can be phased so you live in one part of the home while another is under construction. Full gut renovations typically require temporary relocation for 2-4 months. We help plan the phasing strategy during the design phase.
Remodeling all at once is almost always more cost-effective. You save on mobilization costs, trade scheduling, and material purchases. Flooring, paint, and trim installed throughout the house in one project cost less per unit than the same work done in five separate projects over five years.
Yes. Most whole-home remodels involve structural, electrical, plumbing, and mechanical work that requires permits in Ada County and Canyon County. We manage all permit applications, inspections, and code compliance as part of our scope.
A well-executed whole-home remodel in the Boise market typically recoups 50-70% of its cost at resale, depending on the neighborhood, scope, and finish level. More importantly, it transforms your daily living experience and can add 15-25 years of usable life to an aging home.
We develop a whole-home design package before construction begins — selecting flooring, trim profiles, door hardware, paint colors, lighting fixtures, and plumbing finishes that work together across every room. This ensures a cohesive result rather than a collection of disconnected renovations.
