Yes, it is often best to replace siding and windows together. With the siding removed, installers can access each window’s rough opening, use a full nailing flange, integrate the flashing and weather barrier, and complete both projects in the correct order.
At Wright at Home Roofing & Exteriors, we often speak with homeowners who need new siding but are unsure whether to include aging windows in the same project. The windows may still open and close, but they are drafty, dated, or likely to need replacement within the next few years.
You can replace the windows later. However, understanding how the two systems are installed can help you choose the right timing for your home.
Why Siding Replacement Creates the Right Opportunity
A full siding replacement exposes areas of your home that are normally covered. Once the old siding is removed, the crew can access the weather-resistant barrier and the rough openings where your windows sit.
This access makes it possible to install replacement windows in a sequence similar to how the exterior of a new home is built:
- Prepare the window opening.
- Install and secure the window.
- Apply flashing and weather-sealing materials.
- Integrate the weather-resistant barrier.
- Install the new siding and trim around the window.
When the work is completed in this order, the window, flashing, weather barrier, trim, and siding can function as one coordinated exterior system.
A Better Weather Seal Around Each Window
One of the biggest reasons to replace siding and windows together is the opportunity to create a more complete weather seal.
With the rough opening exposed, installers can use the window’s full nailing flange, connect the flashing tape to the surrounding weather-resistant barrier, and insulate and air seal the opening before the new siding and trim are installed.
The U.S. Department of Energy recommends sealing gaps around window rough openings with appropriate air-sealing materials to help limit airflow around the frame.
This coordinated installation can help reduce the risk of:
- Drafts around window frames
- Gaps in the surrounding air seal
- Water intrusion around the window opening
- Poorly integrated flashing
- Uneven or patched trim details

Can You Replace Windows After Installing New Siding?
Yes, but the installation may be more involved.
Replacing windows later can require removing and resetting siding or trim to reach the rough opening. That additional work may increase the risk of damaged siding, visible fading, or difficulty finding an exact color match several years after the original project.
It can also increase the labor cost. Returning after the siding has been installed may add approximately $100 to $200 in labor per window opening. Across 10 or 15 windows, that additional expense can become significant.
Planning removable trim around the windows during the siding project may make a future replacement easier.
However, that approach should be discussed before the new siding is installed.
When Does a Combined Project Make Sense in Blaine, MN?
Minnesota homes need exterior systems that can handle wind, rain, snow, ice, and major temperature changes. The areas surrounding windows are especially important because several weather-protection components come together in one opening.
Replacing both systems during the same project may make sense when:
- The siding and windows are both nearing the end of their useful lives.
- The windows feel drafty or show signs of moisture.
- You expect to replace the windows within the next few years.
- You want to update the siding, trim, and window styles together.
- You want the best access for flashing and air sealing.
You prefer one coordinated project instead of two separate installations.
When Wright at Home Roofing & Exteriors completes siding replacement and window installation together, our team can plan the exterior as a complete system. The window trim, siding profiles, colors, and weather-protection details can all be considered before installation begins.
If the windows are newer and performing well, replacing them may not be necessary. The right decision depends on their age, condition, efficiency, and how soon you expect to complete the work.
Frequently Asked Questions
Do siding or windows get installed first?
When both systems are being replaced, the windows are generally installed before the new siding. This allows the window flange, flashing, weather-resistant barrier, trim, and siding to be layered in the proper sequence.
Will new siding fix drafty windows?
New siding may improve parts of the exterior, but it will not correct every issue caused by an aging or poorly sealed window. The window frame, glass, rough opening, flashing, and air seal should all be evaluated.
Do all windows need to be replaced with the siding?
Not necessarily. Some homeowners replace every window, while others prioritize openings with drafts, moisture, visible wear, or other performance concerns. Wright at Home Roofing & Exteriors can help determine which windows may benefit from replacement.
Is it cheaper to replace siding and windows at the same time?
It can be. The windows themselves may not cost less, but completing both projects together can reduce the added labor required to remove and reset finished siding around each window later.
