Based on Alderidge Construction’s 2026 planning ranges, a full-home renovation in Langley may cost approximately $190-$600 per square foot, including GST. Cosmetic updates generally fall near $190-$300 per square foot, while comprehensive or down-to-the-studs renovations commonly range from $280-$600 per square foot. Langley projects can sit slightly higher within those ranges than comparable work in Abbotsford, mainly because of travel and logistics. Where a project lands depends on the home, the scope, your finish selections and whether the property is in the City or the Township of Langley.
These are planning ranges, not quotes. Alderidge renovates across every Langley neighbourhood, from established homes in Brookswood and Murrayville to Walnut Grove, Willoughby, Fort Langley and rural acreages, and two homes of the same size can need very different budgets. This guide covers the 2026 ranges, the Langley-specific factors that move costs and timelines, and how to plan a realistic budget before construction begins.

Full-home renovation costs at a glance
Full-Home Renovation Cost in Langley: 2026 Planning Ranges
| Renovation scope | What it may include | Typical 2026 planning range |
|---|---|---|
| Cosmetic whole-home update | Flooring, paint, trim, lighting, selected cabinetry and finish updates without major structural work | $190-$300 per sq. ft. |
| Comprehensive full-home renovation | Kitchen, bathrooms, flooring, interior finishes, layout changes and coordinated mechanical work | $280-$500 per sq. ft. |
| Down-to-the-studs renovation | Major structural work, new building systems, insulation, windows and extensive reconfiguration | $310-$600 per sq. ft. |
| Full-home renovation with an addition | Comprehensive renovation plus new conditioned living space, foundation, structure and exterior work | $310-$600 per sq. ft. |
These ranges include GST and assume standard finishes selected within the project’s agreed allowances. Premium appliances, highly customized millwork, specialty fixtures and owner-directed upgrades can push a project beyond them. Alderidge typically considers renovations starting around $100,000, although smaller projects may be considered depending on scope.
Multiplying your square footage by a range above is useful for early planning, but it is not an estimate. Kitchens, bathrooms and structural work cost far more per square foot than bedrooms or living areas, and many renovations only touch part of the home.
What Makes Langley Renovation Costs Different?
Most cost drivers for a full-home renovation are the same across the Fraser Valley. In Langley, the differences come from travel and logistics, which of the two municipalities reviews the permit, the age of the home and, for rural properties, the land itself.
1. Travel and Logistics
Alderidge is based in Abbotsford, so Langley projects carry some added travel time for crews, trades and deliveries. This is the main reason a Langley renovation can land slightly higher within the planning ranges than a similar project in Abbotsford. It is accounted for in the proposal from the start rather than added later.
2. City of Langley or Township of Langley
Langley is two separate municipalities, each with its own building department, fees and bylaws. The construction itself is priced the same way in both, but permit timelines differ noticeably. In Alderidge’s recent experience:
| Municipality | Typical building permit review | What to expect |
|---|---|---|
| Township of Langley | About 3–6 weeks | Has generally been the faster and more predictable of the two |
| City of Langley | About 6–16 weeks | Varies widely depending on what is being submitted |
Neither municipality has required consultants or steps beyond what Abbotsford requires. Review times shift with each municipality’s workload, so Alderidge confirms current timelines during planning and builds them into the schedule.
3. The Age and Condition of the Home
Alderidge works on Langley homes of every age, and older homes are more likely to need electrical, plumbing, insulation or window upgrades once walls are opened. Asbestos is the most common surprise. In homes built in the 1970s it is most often found in drywall, and other asbestos-containing materials can turn up in homes from other decades. In B.C., homes built before 1990 should be tested before work disturbs those materials, and any abatement adds cost and time before demolition can begin. Read more about what happens when asbestos is found in a home.
4. Acreages and ALR Properties
Acreage renovations in areas such as South Langley, Fernridge and Glen Valley regularly involve items a suburban lot does not, including wells, septic systems and outbuildings, and these can affect both scope and cost. Properties in the Agricultural Land Reserve also come with rules on what can be built or expanded. In Alderidge’s experience, the Township of Langley often has not required consultation with the Agricultural Land Commission for ALR renovations, which can make the approval path simpler than in Abbotsford, where the ALC is typically consulted. These items are reviewed during planning so they are priced from the start.
5. Trees, Heritage and Site Conditions
Both the City and the Township of Langley regulate tree removal on private property. Mature trees near an addition, driveway or excavation area may need a permit, an arborist’s assessment or protection during construction, and tree permits have held up Langley projects in the past. Identifying trees early keeps them off the critical path. Heritage-designated homes, including some in and around Fort Langley, can also carry limits on what can be changed, so confirm any designation with the municipality before design work begins.
6. Kitchens, Bathrooms and Finish Selections
Kitchens and bathrooms carry the highest cost per square foot because they combine cabinetry, fixtures, surfaces, plumbing, electrical and skilled installation. Larger Langley homes with second kitchens, several bathrooms or extensive built-ins will budget differently from a home with one kitchen and two baths. Making selections during design gives the estimate real products and quantities, and changes made after construction starts are one of the most common reasons a renovation ends up over budget. See Alderidge’s kitchen renovation, bathroom renovation and basement and suite conversion services.
Project Example: The Shearwater Main-Floor Renovation
Shearwater is a full main-floor renovation by Alderidge. The original floor plan was divided into separate rooms, and the redesign opened it into one bright, connected space that links to the private green space outside. The new main floor is anchored by custom cabinetry, a handcrafted hood fan, full-span beams, a custom mantel and integrated open shelving, and every wood feature was built in the Alderidge shop.
In the living room, a painted mantel, tile surround and track lighting gave way to a stone fireplace with a custom wood mantel, built-in cabinetry with open shelving, and full-span wood beams overhead.
The kitchen moved from dated oak cabinetry and a fluorescent ceiling panel to white shaker cabinetry, a custom range hood and corner windows that bring in the garden.
In the planning ranges above, a project like this falls in the comprehensive renovation category: layout changes, a new kitchen and coordinated finishes across the main floor. Custom millwork is a large part of what defines the finished space, and it is also one of the clearest examples of how finish selections shape a budget. Because Alderidge builds its cabinetry and millwork in-house, those pieces are designed and priced with the rest of the project rather than under a separate contract.

How Much Contingency Should You Plan?
A contingency is money set aside for conditions that cannot be confirmed until construction, not a spending target. For a full-home renovation, Alderidge generally recommends 10%-20%. A newer home with a clearly defined cosmetic scope may sit at the lower end, while an older home with concealed work, or one that needs asbestos testing and abatement, may need the upper end. Keep a separate allowance for upgrades you might choose along the way. Our article on budgeting for unexpected renovation costs covers this in more detail.
What Is Included in a Full-Home Renovation Budget?
Alderidge develops comprehensive pricing so you see the complete project, not only the visible construction. Depending on the written scope, a Langley renovation budget can account for:
- Planning, design, drawings and engineering
- City or Township permits, fees and inspections
- Required consultants, such as arborists or hazardous materials testing
- Site protection, demolition and disposal
- Structural framing and building-envelope work
- Plumbing, electrical, HVAC and ventilation
- Insulation, drywall and painting
- Cabinetry, countertops and millwork
- Flooring, tile, fixtures, lighting and appliances
- Project management, supervision and cleanup
The exact inclusions, allowances and exclusions are set out in the written proposal for each project.
How Long Does a Full-Home Renovation Take in Langley?
Alderidge’s broad planning range is approximately 1.5 to 6 months or longer for design, selections and permits, followed by approximately 3-12 months for construction. In Langley, permit review is the biggest variable in the first phase: a Township project may clear review in about a month, while a City project can take up to four months depending on the submission. Construction timing depends on structural complexity, inspections, long-lead products and what is found once walls are opened.

Should You Renovate or Rebuild in Langley?
Renovating is not automatically cheaper than building new. The right answer depends on the condition of the existing structure, the value of the lot, zoning, the layout you want and how much of the house can be kept.
| A renovation may make more sense when… | A custom home may make more sense when… |
|---|---|
| You value the location and the existing structure has good potential. | The existing structure cannot support the desired layout economically. |
| Much of the foundation, envelope or structure can remain. | Most systems and finishes need replacing and major structural changes are required. |
| You want to keep the character of the home or neighbourhood. | You want full control over layout, orientation, performance and future use of the lot. |
Alderidge handles both whole-home renovations and custom home construction, so the early conversation can focus on which path suits the property. The home builder calculator is for new-home construction and should not be used as a renovation estimate.
How Alderidge Builds a Reliable Renovation Budget
A reliable budget starts before construction. Alderidge works through planning and design, cabinetry layouts, material selections and required consultants so the major decisions are made while the project is still on paper. During construction, a dedicated project coordinator and online client portal keep scheduling, costs and communication visible. The team includes design, estimating, in-house cabinetry, project coordination and Red Seal-certified carpenters.
