Should You Replace Your Windows When You Replace Your Siding?

When it’s time to give your home a fresh new look, replacing the siding is often one of the first steps homeowners take. New siding improves curb appeal, increases energy efficiency, and protects the structure of your home. But while planning your siding replacement, one important question often arises: Should you replace your windows at the same time?

If you’re considering a siding upgrade and wondering whether new windows should be part of the project, here’s what you need to know.

The Connection Between Siding and Windows

Siding and windows are more closely connected than many homeowners realize. During a siding installation, contractors must carefully work around existing windows. If your windows are old or damaged, it can complicate the siding process—and ultimately affect the overall outcome.

Replacing both your windows and siding in a single project can be more efficient, both in terms of labor and long-term performance. Let’s explore the pros and cons of coordinating these two home improvement projects.

Advantages of Replacing Windows and Siding Together

1. Improved Energy Efficiency

Older windows often leak air, leading to higher heating and cooling bills. When you pair energy-efficient windows with new siding—especially insulated siding—you create a more airtight home envelope. This combination significantly reduces drafts and helps maintain a consistent indoor temperature, saving money year-round.

2. Better Weatherproofing

Siding installation includes adding flashing and sealants around windows to keep out water and moisture. If your windows are older, they may not provide a tight seal even with new siding. Upgrading them simultaneously ensures all layers of your exterior are properly integrated for maximum protection from the elements.

3. Cost Efficiency

Doing both projects together may reduce overall labor costs. Contractors can install trim, flashing, and insulation more efficiently without having to work around or return for outdated windows. You’ll also avoid the added expense of removing and reinstalling siding later if you decide to upgrade your windows down the road.

4. Streamlined Aesthetics

New siding gives your home a facelift—but mismatched, aging windows can diminish the visual impact. Replacing your windows along with the siding ensures a cohesive, modern look that adds value and curb appeal.

5. Fewer Disruptions

Home renovations can be disruptive. Combining window and siding projects minimizes the number of days contractors need to be on site. You’ll go through the noise and dust once instead of twice.

When You Might Wait on Window Replacement

While replacing siding and windows together has many benefits, there are a few situations where it may make sense to wait on new windows:

• Budget Constraints: If your budget is tight, you might prioritize siding, especially if the existing windows are in good shape.

• Recent Window Installation: If you’ve already replaced your windows in the last few years, there may be no need to do it again—unless they were improperly installed or don’t match the new siding.

• Specific Design or Energy Goals: Sometimes, homeowners want custom or specialty windows that require a longer planning and ordering process. In that case, you might proceed with siding first while finalizing window decisions.

However, it’s crucial to let your contractor know if you plan to replace windows later. They can install siding in a way that allows for future window replacement without damaging the new exterior.

Signs Your Windows Should Be Replaced Now

Before making a final decision, evaluate the condition of your current windows. Here are some signs it’s time to upgrade:

• You feel drafts near closed windows.

• Window frames show signs of rot or warping.

• Windows are difficult to open or close.

• Condensation appears between panes.

• Your energy bills are consistently high.

• The windows are more than 15–20 years old.

If any of these issues apply to your home, it’s a smart move to replace the windows during your siding project.
