Serving Waukesha, Milwaukee County, and Southeastern Wisconsin, Illinois and Connecticut

REXX Roofing isn’t just about roofing — we’re about protecting every part of your home’s exterior. That includes high-performance, great-looking window and door replacements that make a difference you can see and feel.

Whether your windows are drafty, hard to open, or just plain outdated — or your doors have seen better days — we’ll help you choose replacements that elevate curb appeal and reduce energy bills.

We only use products we trust — windows and doors built for Midwest winters, summer humidity, and everything in between. It’s about performance and aesthetics — insulation that saves you money, with styles that boost the beauty of your space inside and out.

What We Replace:

Why Replace Your Windows or Doors?

Lower Your Energy Bills
New windows and doors with insulated glass, low-E coatings, and tight weather seals can significantly reduce heat loss and A/C use — saving you money every month.
Improve Curb Appeal
Swap old, foggy panes or warped doors with sleek new finishes that make your home stand out from the street — or feel more inviting up close.
Noise Reduction
Modern windows cut down on road and neighborhood noise. Sleep better, relax more, and enjoy peace and quiet in your own home.

Boost Home Security
Upgraded locking systems, impact-resistant glass, and secure frames give your home added protection from both weather and unwanted visitors.
Easier to Use & Clean
Tired of windows that don’t budge or doors that drag? Our replacements glide smoothly and offer tilt-in cleaning and other smart features.
Maximize Natural Light
Larger panes, clearer glass, and well-positioned windows or doors bring in more sunlight — and make your space feel bigger and brighter.
