Overcash Siding installs replacement windows for Madison-area homeowners, most often as part of a siding project when the walls are already open and flashing can be done right. New energy-efficient windows cut drafts and heat loss, and pairing them with re-siding ensures the window-to-wall connection is properly flashed and sealed.
Windows are one of the biggest sources of heat loss in a Wisconsin home. Old single-pane or failing double-pane units let heat pour out in winter and drive up your bills, and worn seals and flashing let water and air infiltrate around the frame. Replacing them with modern, energy-efficient units improves comfort year-round.
The best time to replace windows is often when you are re-siding, because the wall detailing around each opening — the flashing and weather barrier that keep water out — is exposed and can be integrated correctly. Doing both together avoids cutting into brand-new siding later and guarantees a properly sealed, weather-tight opening.
Signs It Is Time for New Windows
- Drafts, cold spots, or condensation between the panes
- Windows that stick, will not stay open, or are painted shut
- Rising heating and cooling bills
- Rot or water damage around the frames
- You are re-siding and want the openings flashed and sealed correctly
Why Windows and Siding Go Together
The connection between a window and the wall is a critical waterproofing detail. When we re-side a home, the weather barrier and flashing around each opening are exposed, so it is the ideal moment to set new windows and integrate that flashing seamlessly. Replacing windows separately after new siding means cutting back into the finished wall, which is why we recommend coordinating the two.
Energy Efficiency in Our Climate
Modern replacement windows use insulated glass, low-E coatings, and better frames and seals to dramatically cut the heat loss of old units. In our heating-dominated climate, that shows up as fewer drafts, warmer rooms near the windows, and lower bills. We will help you choose units suited to Wisconsin winters.

Interior and exterior trim complete a clean, draft-free installation.
What Affects Window Replacement Cost
Window cost depends on the units and the scope. Key drivers:
- Number & size of windows
- More and larger openings increase material and labor.
- Window type & efficiency
- Frame material, glass package, and style affect price.
- Paired with siding
- Doing windows during a re-side can be more efficient than a separate project.
- Frame repairs
- Rot or damage around existing openings adds scope.
