Window Replacement During a Renovation in Vancouver: What Homeowners Need to Know

Replacing windows during a whole-home renovation is one of the highest-return upgrades a Vancouver homeowner can make. Doing the work with walls already open saves $150–$400 per window in labour, and the combined project qualifies for Energy East rebates unavailable to standalone replacements. Reno Stars has managed window-replacement phases in over a dozen Greater Vancouver whole-home projects.

Why Replace Windows During a Renovation?

Vancouver's coastal climate puts older windows under constant stress. A standard vinyl window lasts 15–25 years; by the time a whole-home renovation is underway, the original windows are often at the end of their service life. Tearing into walls twice—once for the renovation, then again years later for window replacement—doubles the labour cost and disrupts finished interiors. Reno Stars recommends replacing all windows in scope during the single renovation phase, when contractors already have walls open and scaffolding in place.

Window Replacement Costs in Vancouver (2026)

Material and installation costs vary by window type and opening size. The figures below reflect current Vancouver-area pricing from supplier quotes seen on recent Reno Stars projects.

Window Type	Cost per Window (material + install)	Typical Lifespan
Vinyl (standard)	$500 – $900	15–20 years
Fibreglass	$800 – $1,400	25–35 years
Aluminium-clad wood	$1,200 – $2,200	35–50 years
Custom geometric	$1,800 – $3,500+	40+ years

These are per-window all-in costs for a typical 900 × 1,200 mm rough opening. Larger formats, custom shapes, or triple-pane specifications for north-facing walls push costs toward the upper end. A standard three-bedroom Vancouver home needs 12–18 windows; total project cost typically falls between $8,000 and $28,000 before rebates.

Energy East Rebates for Window Upgrades

Energy East (theBC provincial efficiency program) offers point-of-sale rebates on windows meeting specific U-factor thresholds. As of 2026, qualifying windows receive $40–$85 per window depending on performance tier. For a whole-home replacement of 15 windows, rebates can total $600–$1,275 applied directly at the point of purchase. Reno Stars collects the necessary documentation—U-factor certification, invoices, and EnerGuide ratings—from the window supplier and submits the rebate package on the homeowner's behalf.

Step-by-Step: How Reno Stars Integrates Window Replacement

Reno Stars sequences window work within the broader renovation timeline so it does not delay other trades. The typical sequence:

1. Pre-demolition survey: Reno Stars measures every rough opening and catalogues window conditions before any walls are opened. This data drives the window order.
2. Order and lead time: Custom windows typically require 4–8 weeks from order to delivery. Reno Stars places the order in weeks 1–2 of the project, before framing begins.
3. Installation before insulation and drywall: Window frames go in once the building envelope is weatherboard. This lets the thermal envelope be closed properly before insulation is installed.
4. Flashing and sealing: Reno Stars specifies continuous exterior flashing and air-seal taping at every rough opening—a step often skipped by single-trade window companies.
5. Interior trim and painting: After window installation, the interior trim phase proceeds normally within the overall paint schedule.

What Vancouver's Building Code Requires

Vancouver's Building By-law requires replacement windows to meet the same thermal performance standards as new construction when more than 25% of the window assembly is altered. Reno Stars obtains the necessary permits and ensures all window installations pass the required field inspection. For strata buildings, the project also requires council approval and compliance with the Strata Property Act—which Reno Stars manages as part of the permit package.

Does Window Replacement Affect My Renovation Timeline?

When ordered and sequenced correctly, window replacement adds approximately 5–8 days to a whole-home renovation timeline. Reno Stars typically starts window installation during weeks 6–8 of a 16–20 week project, once structural work is complete and before insulation begins. The windows arrive pre-finished; no on-site painting or finishing is required, which eliminates a common source of delay.

FAQ: Windows and Whole-Home Renovation in Vancouver

Can I replace just a few windows during a renovation, or do I have to do all of them?

You can replace individual windows, but Reno Stars generally recommends a full replacement within the renovation scope. Mixing old and new windows creates thermal inconsistency and reduces the overall energy performance of the home. Doing all windows at once also maximises Energy East rebates, which are applied per window on a tiered basis.

Are there strata restrictions for window replacement in Vancouver?

Yes. Most Vancouver strata buildings have bylaws governing exterior appearance, including window specifications. Reno Stars obtains council approval before ordering and coordinates specifications (frame colour, hardware finish, glass type) to match strata requirements. This is included in the permit management fee.

What is the U-factor requirement for Energy East rebates?

As of 2026, Energy East requires a U-factor of 1.22 W/m²K or better for windows to qualify for the mid-tier rebate, and 1.05 W/m²K or better for the top tier. Reno Stars specifies windows meeting the top-tier threshold on all projects to maximise the rebate.

How do I know if my walls need to be opened for window replacement?

Full-frame window replacement—removing the entire window assembly including the frame—requires opening the wall. This is the approach Reno Stars uses during renovations, as it allows inspection of the rough opening, replacement of any rotted framing, and proper flashing. Retrofit or insert installations (new window into old frame) are not recommended during renovations because they leave the old frame and its potential moisture damage in place.

Can Reno Stars handle window replacement on a room-by-room basis rather than a whole-home project?

Yes. Reno Stars offers window replacement as a standalone trade within a broader renovation, or as a focused project on its own. Standalone window replacement projects typically run 2–4 weeks from permit to completion.
