If you’re planning to replace your windows, one of the most common questions homeowners ask is:
“How long does window replacement take in Ottawa?”
The short answer:
Most projects take 1–3 days for installation, but the full timeline — from quote to completion — is usually 4–8 weeks depending on the season and product availability.
Here’s what to expect.
Step 1: Consultation & Quote (1–7 Days)
The process typically begins with:
-
In-home measurement
-
Product selection
-
Performance recommendations
-
Written quote
In Ottawa, most reputable window companies can schedule a consultation within a few days, especially outside peak seasons.
Step 2: Ordering & Manufacturing (3–6 Weeks)
After you approve the quote and place a deposit, your windows are custom-manufactured.
In Ottawa, production timelines vary depending on:
-
Double vs triple pane selection
-
Frame material (vinyl, hybrid, etc.)
-
Custom sizing
-
Seasonal demand
Spring and fall are peak seasons, which can extend wait times.
Step 3: Installation (1–3 Days)
For an average Ottawa home:
-
8–12 windows can usually be installed in 1–2 days
-
Larger homes may take 2–3 days
Professional installers remove old windows, prepare openings, install new units, seal properly, and finish interior trim.
Weather can occasionally affect scheduling during winter months.
Step 4: Final Inspection & Cleanup (Same Day)
A quality installer will:
-
Inspect sealing and leveling
-
Verify smooth window operation
-
Clean work areas
-
Review warranty details
The entire on-site process is usually completed quickly and efficiently.
