Should You Replace Windows and Siding at the Same Time in Minnesota?
If your windows are drafty and your siding is worn, cracked, or fading, replacing both at the same time may save you headaches, improve your home’s protection, and give you a cleaner finished look. For many Twin Cities homeowners, a coordinated window and siding replacement is a smarter long-term plan than fixing one part of the exterior now and disturbing it again a few years later.
Minnesota weather is hard on a house. We deal with bitter cold, snow, ice, wind, heavy rain, humid summers, and freeze-thaw cycles that can expose weak spots around windows, siding, trim, and flashing. If one part of your exterior is failing, it is worth looking at how the rest of the system is holding up too.
At Lakeside Exteriors, we help homeowners across the Twin Cities make sense of their options. There is no one-size-fits-all answer. But when windows and siding are both nearing the end of their useful life, doing the work together can lead to a better result.
Quick Answer: Is It Better to Replace Windows and Siding Together?
Often, yes.
Replacing windows and siding at the same time gives your contractor access to the wall areas around your windows. That makes it easier to inspect for water damage, improve flashing and weather protection, update trim, and create a finished look that fits your home.
It can also mean:
Less disruption than scheduling two separate exterior projects
Better coordination between window installation, siding, trim, and flashing
A more finished, balanced exterior appearance
Fewer chances of removing or damaging newer siding later
One clear plan, one project schedule, and one contractor managing the work
This does not mean every home needs both projects at once. If your siding is in good condition and your windows are failing, it may make sense to replace the windows first. The right choice depends on the age and condition of your home, your budget, and what we find during the exterior review.
Signs You May Need Window and Siding Replacement
Many homeowners first notice one issue: a cold room, peeling paint, cracked siding, or a window that is hard to open. But exterior problems often connect to one another.
You may want to consider replacing windows and siding together if you see several of these signs:
Cold air or drafts near your windows in winter
Condensation between the glass panes
Windows that stick, leak, rot, or will not lock well
High heating or cooling bills
Cracked, warped, loose, faded, or damaged siding
Soft or rotten wood around window trim
Peeling exterior paint near windows
Water stains inside near window openings
Gaps around window frames or siding seams
A home exterior that looks dated or no longer matches your goals
A drafty window may be an old-window problem. But it can also point to gaps, poor insulation, damaged trim, or moisture around the opening. New siding may improve curb appeal, but the best time to address weak windows and trim is often before the siding is installed around them.
Why the Order Matters
When homeowners ask, “Should I replace windows before siding?” the answer is usually: yes, if both need to be replaced.
That does not mean every job follows the exact same steps, but it is generally better to complete window replacement before the final siding and trim work. Here is why.
New Windows Can Be Installed Correctly
A quality window installation is about more than placing a new window in the opening. The area around the window needs to be protected from air and water.
During a full-frame window replacement, the old window and frame are removed so the installer can inspect the opening. This can reveal problems hidden behind trim or siding, such as:
Water damage
Rot
Gaps around the frame
Old insulation that is no longer doing its job
Improper flashing
Areas where water may be getting behind the exterior
If new siding goes on first, it may need to be removed or altered later to complete the window project the right way.
Siding and Trim Can Fit the New Windows
New windows can have different frame depths, trim styles, and exterior details than old windows. Replacing the windows first gives you more control over the finished look.
Your contractor can coordinate:
Window trim width and style
Siding transitions around the window
Color combinations
Exterior casing details
Flashing and water management
The look of your home from the street
The end result is usually cleaner than replacing siding now and trying to make future windows fit around it later.
It May Help Avoid Duplicate Work
Imagine installing new siding, trim, and paint around old windows—then learning two years later that the windows need replacement. Parts of the newer exterior may need to be removed or adjusted so the new windows can be installed and flashed correctly.
Planning both projects together may help you avoid paying twice for parts of the job.
Benefits of Replacing Windows and Siding Together
A combined exterior project is a bigger decision, but it can have real benefits for the right home.
Better Protection From Minnesota Weather
Your windows, siding, trim, and flashing all work together to help keep water and outside air out of your home. If one part is weak, it can affect the others.
Minnesota homes go through major temperature swings. Materials expand and contract. Snow melts, freezes, and melts again. Rain and wind can push moisture into small openings around siding and windows.
Replacing windows and siding at the same time gives you the chance to update the exterior as one connected system instead of treating each issue separately.
A More Comfortable Home
Old or poorly performing windows can make rooms feel cold in winter and hot in summer. You may notice drafts near the glass, uncomfortable rooms, or furniture fading from too much direct sun.
Modern replacement windows can offer features such as:
Low-E glass to help manage heat from the sun
Insulated glass packages
Better weatherstripping
Stronger frames
Improved locks and operation
Options for double-pane or triple-pane glass
The best window for your home depends on the opening, direction of the sun, your comfort goals, and your budget. Lakeside Exteriors installs replacement windows from trusted brands including Andersen, Marvin, Pella, and ProVia.
A Stronger, More Updated Look
New siding and new windows can completely change the way a home looks.
You can update faded colors, old trim, mismatched window styles, and worn exterior details all in one plan. Instead of your new siding making older windows stand out, the finished exterior looks intentional.
This is especially helpful for homeowners who are planning to stay in their home for years—or want stronger curb appeal before selling.
One Contractor and One Clear Plan

Frequently Asked Questions
Is it cheaper to replace windows and siding together?
It can be more efficient because the project is planned as one system. In some cases, it can reduce repeat labor or prevent the need to remove and adjust newer siding later. The exact cost depends on your home, materials, window count, trim needs, and any repairs found during the project.
Should windows be replaced before siding?
If both need replacement, windows are usually installed before the final siding and trim work. This allows the contractor to inspect the opening, handle flashing and weather protection, and make the new siding fit cleanly around the new windows.
Can new siding fix drafty windows?
New siding may help address gaps in the wall system, but it does not repair failed windows. If the window itself is old, leaking, damaged, or poorly insulated, replacing the window may be the better solution.
Do I need full-frame replacement windows with new siding?
Not every home requires full-frame replacement. However, full-frame installation allows the old frame to be removed so the opening can be inspected and insulation and flashing can be addressed. Lakeside Exteriors specializes in full-frame window replacement when it is the right fit for the home
How long does a window and siding replacement project take?
Project length depends on the number of windows, the size of the home, material availability, weather, repair needs, and the scope of trim and siding work. A clear project plan and communication from your contractor are important so you know what to expect before work begins.
