Overcash Siding installs and replaces entry and patio doors for Madison-area homeowners. A properly installed door seals out drafts and water, improves security and curb appeal, and — like windows — is often best handled during a siding project when the surrounding wall and flashing are exposed.
An old or poorly installed exterior door is a constant source of drafts, water intrusion, and heat loss, and it is the first thing visitors notice. Replacing an entry or patio door upgrades your home’s comfort, efficiency, security, and appearance in a single project.
As with windows, the door-to-wall connection is a key waterproofing point. When we are already re-siding a home, integrating a new door with the weather barrier and flashing is straightforward and produces a tighter, longer-lasting installation. We also install doors as standalone projects with the same attention to sealing.
When to Replace an Exterior Door
- Drafts, daylight, or water intrusion around the door
- A door that sticks, sags, or no longer latches securely
- Rot or damage on the door, frame, or threshold
- Outdated appearance or poor curb appeal
- You are re-siding and want the opening flashed and sealed correctly
Entry Doors and Patio Doors
Entry doors set the tone for your home and must seal tightly and lock securely. Patio and sliding doors bring in light and connect to outdoor space but are large openings that need careful sealing to avoid drafts and leaks. We install both, with proper flashing, insulation, and hardware, so they perform as well as they look.
Sealing and Efficiency in Winter
A door is only as good as its seal. We set doors level and plumb, flash and insulate the rough opening, and detail the threshold and weatherstripping so cold air and water stay out. In a Wisconsin winter, that airtight installation is what turns a nice-looking door into a comfortable, efficient one.

What Affects Door Installation Cost
Door cost depends on the door and the opening. Key drivers:
- Door type
- Entry, storm, sliding, and French/patio doors vary widely in price.
- Material & features
- Fiberglass, steel, or wood, plus glass, hardware, and finish options.
- Opening modifications
- Resizing an opening or repairing rot adds scope.
- Paired with siding
- Installing during a re-side can streamline the flashing work.
