Costs

Estimates and pricing

How the cost estimator works and how to get an exact number.

Try the estimator →
It is a budgeting range built from typical installed prices in BC. Your actual price depends on your home, so we confirm it with an on-site assessment and a written quote.
The range covers materials, labour and installation for the options you choose. Repairs to hidden damage, permits and special orders are confirmed at your assessment.
Window size, style, glass options and siding profile all change the price, and the tool does not know those details yet. A visit narrows the range to a firm number.
No. The estimator does not ask for your name, email or phone number. You only share those if you decide to book an assessment.
Not with this tool. Call us or request a quote for doors, flashing and larger exterior projects and we will price them for you.

Siding and cladding

Siding replacement and repair

What our siding service includes, and what happens if we find damage.

Siding service →
Sometimes. If damage is localized and a matching material is available, a repair can be a lasting fix rather than a full replacement. We’ll tell you honestly which makes sense during your assessment.
It can. Once your existing siding is off, we inspect the sheathing and moisture barrier underneath and quote any envelope repairs needed before new siding goes on.
We stop, show you what we found, and agree on next steps before any additional work or cost.
BC Building Code requires one on most residential exterior walls, and we install it as standard on our siding replacements.
Fiber cement holds up extremely well to our rain; vinyl is a strong budget option; wood and composite suit homes where a specific look matters. We’ll help you weigh it against your home and budget.
Most residential projects take 1 to 3 weeks depending on size and complexity. You’ll get a firm estimate after your free consultation.
Siding guide

Choosing siding

Timing, cost, warranty and permits when replacing your siding.

Siding comparison guide →
A typical full-home siding replacement takes 1 to 3 weeks depending on the size of the home, the material chosen and weather conditions. Fiber cement and steel take slightly longer due to heavier material handling and more detailed flashing work. We provide a project timeline before work begins.
In some cases, yes, but we generally recommend removing old siding first. That lets us inspect the sheathing and house wrap underneath for moisture damage, replace any deteriorated material and install a proper weather-resistive barrier. Installing over old siding can trap moisture and void manufacturer warranties.
Vinyl has the lowest upfront cost at $5 to $8 per square foot installed and needs virtually no maintenance. Fiber cement (James Hardie) offers the best long-term value once you factor in lifespan (30 to 50 years), fire resistance and the home value increase it provides. The right choice depends on your budget and how long you plan to stay.
Yes. Siding replacement consistently ranks among the highest ROI home improvement projects in Canada. Fiber cement typically recoups 75 to 85% of its cost at resale, while vinyl recoups 70 to 75%. New siding also improves curb appeal and can reduce energy costs.
Signs you need full replacement include widespread rot or moisture damage, warping or buckling across multiple areas, persistent mould behind the siding, heavily faded or chalking colour, or energy bills that keep climbing. If damage is limited to one small area, a repair may suffice. We offer free inspections.
We remove the old siding and inspect the existing house wrap (weather-resistive barrier). If it is damaged, deteriorated or does not meet current code, we replace it before installing the new siding. This is critical for long-term moisture management in BC’s wet climate.
Most like-for-like siding replacements in the Lower Mainland do not need a building permit. If we are changing the cladding system, adding rain screen or making structural changes, a permit may be required. We advise during quoting and handle any necessary permits.
Coverage depends on the material. James Hardie offers a 30-year non-prorated product warranty, Mitten vinyl a lifetime limited warranty with its No Fade Promise, and LP SmartSide a 5/50 warranty. On top of manufacturer warranties, Tomron provides its own workmanship warranty covering installation quality.
Windows

Window replacement

How we replace windows and what to expect.

Window replacement →
A single window usually takes a few hours. A whole-house replacement typically takes 2 to 5 days, depending on the number of windows and how easy they are to reach.
Retrofit fits a new window into the existing frame, which is faster and less disruptive. Full-frame removes the whole assembly down to the rough opening, so the surrounding structure can be inspected and repaired.
Yes. Modern double or triple-pane windows with low-E coatings can reduce heat loss through your windows by 30 to 50 percent compared with older single-pane or failed double-pane units.
We install casement, awning, picture, arch, sliding, double-hung and tilt-n-turn windows in a range of frame materials, including vinyl and fiberglass.
Yes. Installations are backed by manufacturer warranties on materials, plus our own workmanship guarantee.
Window replacement is often eligible for BC and federal energy rebate programs. Eligibility changes, so we point you to the current programs when we quote.
Windows guide

Buying windows

Timing, glass choices and warranties when choosing new windows.

Window buying guide →
Full replacement is usually more cost-effective because setup charges are shared, but phased replacement is available.
Retrofit keeps your existing frames. Full-frame removes everything so we can inspect and flash properly, and is recommended when frames are damaged.
It is worth considering for north-facing walls or premium builds, and typically costs 25–40% more than double-pane.
Fog or condensation between the panes, drafts, windows that are hard to open, rot, higher energy bills or excess outside noise.
Aim for 1.40 or lower for Energy Star Zone 2. Single-pane windows sit around 5.0, while quality double-pane Low-E is 1.4–1.6.
Energy Star windows may qualify for programs such as CleanBC Better Homes and the Canada Greener Homes Grant. See our BC rebates guide for current details.
At minimum, a 20-year frame warranty and a 15-year sealed-unit warranty. Ply Gem offers lifetime frame coverage.
Glass

Glass and sealed units

What is inside a window and which glass suits BC homes.

Glass performance guide →
An insulated glass unit (IGU), also called a sealed unit, is two or three panes of glass separated by a spacer bar and sealed together, usually with argon between the panes.
R-value measures resistance to heat flow, so higher is better. U-value measures heat loss, so lower is better.
For most BC replacements it is the best balance of cost and performance. Triple glazing suits north-facing windows and premium builds.
Not noticeably. Unlike tinted glass, Low-E coatings are virtually invisible and keep a clear, neutral appearance.
Yes. Better insulation keeps the inner glass warmer, which reduces condensation, and multi-pane gas-filled units reduce outside noise.
No. The window brands we carry all use Vitrum sealed units, so R-values and Low-E performance are consistent.
It means Vitrum’s sealed units meet high standards for design, manufacture and long-term performance.
We recommend a configuration based on your home’s orientation, energy goals and budget. Book a free consultation and we will walk you through it.
Window technology

Reading window ratings

U-factor, SHGC and what the numbers on a window label mean.

See the window demo →
U-factor measures how much heat passes through a window, in W/m²·K. Lower is better. Single-pane sits around 5.0, while modern double-pane with Low-E and argon is 1.4–1.6. Aim for 1.40 or lower for Energy Star qualification and rebate eligibility.
Solar Heat Gain Coefficient measures how much solar heat passes through the glass, from 0 to 1. The best value depends on orientation: south-facing windows benefit from 0.30–0.40 and west-facing from 0.20–0.25. A balanced 0.22–0.35 works for most BC homes.
Low-E 270 is a passive coating with an SHGC of about 0.34, suited to north and east windows. Low-E 366 is a solar control coating with an SHGC of about 0.22, better for south and west exposures. Many homes use both.
Triple-pane raises glass costs 30–50% but delivers a U-factor of 0.8–1.0 versus 1.4–1.6 for double-pane. It is most valuable for large north-facing windows, bedrooms and noise-sensitive rooms. For most BC homes, double-pane with Low-E and argon is the better value.
Argon is an inert gas that conducts less heat than air. Sealed between the panes, it reduces convection and conduction and improves insulation by roughly 30% over air-filled units. It is colourless, odourless and non-toxic.
Check four numbers: U-factor (lower is better), SHGC (depends on orientation), visible transmittance (typically 0.40–0.70 for natural light) and Energy Rating (higher is better, 25+ for Energy Star). ER is unique to Canada and balances heat loss against solar gain.
The frame contributes about 20% of a window’s total U-factor. Multi-chambered vinyl frames trap still air, which slows heat transfer without the upkeep of wood.
Aluminum spacers create a thermal bridge at the glass edge and cause condensation. Warm-edge spacers can cut edge heat loss by up to 65%, keeping the edges warmer.
Doors

Door replacement

Materials, timing and finishes for new entry doors.

Door replacement →
A standard entry door or patio door replacement typically takes one day. Installations with structural changes or custom sizing can take 2 to 3 days.
Fiberglass is the most popular choice in the Lower Mainland. It resists moisture, does not warp, needs little maintenance and insulates well. Steel and solid wood are good options too, depending on your priorities.
We install a full range of exterior doors, including entry doors, sliding patio doors and French doors.
Yes. We offer a variety of finishes, colours and hardware options to complement your home.
Every installation includes proper insulation, flashing and sealing to keep drafts and moisture out.
A door that is installed correctly, with a waterproofed sill and proper flashing, can perform for 30 years or more.
Metal flashing

Metal flashing

How flashing protects your walls and when it needs replacing.

Metal flashing service →
Common signs include water stains on interior walls near windows or doors, rust or gaps in the exterior flashing, peeling paint around frames, and musty odours from hidden moisture. The only way to be sure is to have it inspected, and our inspections are free.
In many cases, yes. Depending on the location and extent of the problem, we can selectively remove and reinstall siding panels to reach and replace failed flashing without a full tear-off.
It depends on how many openings and transitions need work, how accessible they are, and the metal used. A spot repair costs far less than a whole-house job. We give you a written proposal after a free inspection, so you know the price before we start.
Properly installed aluminum or galvanized steel flashing can protect a wall for decades. Flashing fails early when it’s poorly detailed, damaged, or installed without regard to the layers around it, which is why installation matters as much as the metal.
Yes, whenever the exterior is already open it is the best and most cost-effective time to install new flashing. Skipping it can undo the value of new windows or siding by leaving the same weak points behind.
Caulking is a short-term seal that dries out and cracks. Flashing is a mechanical barrier that physically directs water away from the wall. Caulk can support flashing, but it shouldn’t replace it.
Building envelope

Building envelope repair

Signs of failure, costs and how repairs are done.

Building envelope service →
Common signs include drafts near windows and doors, condensation on interior glass, higher heating bills, mould near exterior corners, peeling paint or stains under window sills, and musty smells along exterior walls. Any one of these is worth having inspected.
Yes. Sealing air leaks and improving insulation can noticeably lower heating and cooling costs, and many homeowners see savings in the range of 20 to 40 percent. Results depend on your home, and we will tell you what to realistically expect after the assessment.
It depends on the size of the home and how much of the wall system is affected. We inspect first, then give you a written quote so you know the scope before any work starts.
It depends on the scope and your municipality. Cosmetic repairs often do not, but rebuilding wall assemblies can. We can advise on what applies to your project.
A localized repair may take days, while a full-wall rebuild can take several weeks. Weather and the extent of hidden damage affect timing, and we will give you a schedule with your quote.
Often, yes. If damage is localized, we can open up and repair only the affected sections, then match the new cladding. We will let you know if full replacement makes more sense.
Renovations

Home renovation

Timelines, permits and living at home during a renovation.

Home renovation →
It depends on scope. A bathroom often takes 2 to 4 weeks, a kitchen 4 to 8 weeks, and a whole-house renovation several months. You get a detailed schedule during planning.
Yes. We manage the full permitting process for projects that need it, including applications, inspections and final sign-off.
In most cases, yes. We contain work areas, control dust and debris, and keep access to essential spaces.
It depends on the size, layout and finishes. We visit first, discuss your goals and budget, then give you a written proposal with transparent pricing.
We serve homes across the Lower Mainland, from Maple Ridge and Coquitlam to Vancouver and Surrey. Contact us and we will confirm your location.
Yes. You have direct access to your project lead throughout, so you never have to chase multiple contractors.
Rebates

BC rebates and incentives

How rebate programs work and what to check before you buy.

Rebates guide →
Rebates are tied to the product and the program rules, not the installer. Our ENERGY STAR certified windows and doors are chosen with common program requirements in mind, and we provide the itemized invoice you will need.
No. Programs set their own eligibility, funding limits and deadlines, and they can change or pause at any time. Always confirm with the program before you buy.
Sometimes. Stacking rules vary by program, so check each program’s terms or ask a Better Homes BC energy coach.
Some programs ask for one, others do not. The program page will tell you whether an assessment is required before or after the work.
No. The federal Canada Greener Homes Grant has closed to new applicants. Provincial and utility programs are the place to look now.
Often yes. Starting installation before approval can make you ineligible, so confirm this first.
Applications are usually made by the homeowner. We supply the documents you need, such as itemized invoices and product specs, and can answer questions along the way.
Programs commonly require ENERGY STAR certified windows and doors for your climate zone. Ask us about specific models and we will share the ratings.
