How Long Does It Take to Replace Windows? A Complete Guide for Metro Detroit Homeowners
Replacing old, drafty windows is one of the best upgrades you can make to your home. New windows improve energy efficiency, increase comfort, reduce outside noise, and boost curb appeal. But one of the most common questions homeowners in Metro Detroit ask is:
“How long will it take to replace my windows?”
The answer depends on a few factors, including the number of windows, the condition of your existing frames, and whether you’re choosing standard replacements or custom designs. In this guide, we’ll break down everything you need to know about window replacement timelines so you know what to expect.
Average Time to Replace Windows
In most cases, a professional crew can replace 10–15 windows in a single day. On average, each window takes about 30–60 minutes to install, depending on the style and the condition of the opening.
For example:
-
One or two windows: Just a few hours
-
A full home with 10–20 windows: One to two days
-
Custom or specialty windows: May take several days or require longer lead times for manufacturing
If your home only needs a handful of windows swapped out, the process is quick. But for larger projects, expect a full day or more of work.
Factors That Affect How Long Window Replacement Takes
1. Number of Windows
Naturally, the more windows you’re replacing, the longer the project will take. A single bay or picture window can take longer than three smaller double-hung windows because of its size and complexity.
2. Window Style
Different styles take different amounts of time to install.
-
Double-hung or casement windows: Typically the fastest installs
-
Bay or bow windows: Require more labor, framing adjustments, and sealing
-
Custom-shaped windows: May take extra care and precision
3. Condition of the Existing Frames
If your current window frames are in good shape, installers can usually slide in a replacement window with minimal adjustments. But if there’s rot, water damage, or structural issues, repairs may be needed before new windows can go in, adding time to the project.
4. Accessibility
Windows that are easy to reach, like on the ground floor, go faster. Upper-story or hard-to-reach windows may take longer, especially if ladders or scaffolding are required.
5. Custom vs. Standard Sizes
Standard-size replacement windows can be ordered and installed relatively quickly. Custom windows, however, may require several weeks of manufacturing before installation even begins.
6. Weather and Season
Here in Metro Detroit, the weather plays a big role. Window replacement crews work year-round, but extreme cold, snow, or heavy rain can slow down the process or cause rescheduling.
What to Expect During the Window Replacement Process
Knowing what happens on installation day can help you prepare your home and reduce delays.
Step 1: Preparation
Your contractor will usually ask you to clear the area around each window inside and outside. Move furniture, blinds, curtains, and anything blocking access.
Step 2: Removal of Old Windows
The crew will carefully remove your old windows and inspect the frames. If there’s hidden damage, this is when they’ll repair or reinforce the opening.
Step 3: Installing the New Windows
The replacement windows are placed into the openings, adjusted for a perfect fit, and sealed against drafts and moisture.
Step 4: Insulation and Sealing
Insulation foam and caulk are applied to ensure energy efficiency and prevent leaks.
Step 5: Finishing Touches
Trim pieces and hardware are reinstalled or replaced. The crew cleans up and hauls away your old windows.
For most homeowners, the process is quicker and less disruptive than expected.
