Key Signs it is time to replace your windows or patio doors
01
Moisture Issues
If you've seen water between glass panes, leaking, water stains or evidence of wood rot - those are signs that excess moisture is accumulating where you can't see it. This can lead to damage, including mold, mildew and warping.
02
ENERGY EFFICIENCY
If you need to wrap up in a blanket to sit by your windows or have to close your blinds to keep out the hot summer sun, it may be time to switch to energy-efficient Marvin windows.
03
NOT WORKING PROPERLY
If you struggle to open your windows or can no longer lock your patio door, it may be time to save yourself the hassle and consider replacing with new, durable Marvin Replacement windows and doors.
04
Design Refresh
If your windows and doors aren't making the design impact you'd like inside or out, or they're limiting your home's liveable space, replacing your windows and doors can improve how you live and feel in your home.

We Use Ultrex® Fiberglass for Unmatched Performance
Superior Material
We know there are many window options out there and choosing the right one is difficult. Once you learn about our Ultrex Fiberglass, you'll see why we're so proud of it. Compared to other materials, Ultrex Fiberglass is the strongest window framing material in the replacement industry.
A Fit That Never Quits
Our proprietary acrylic finish is 3x thicker than the competition. Our finish resists scratching and denting, and performs so well that we offer dark colors without fear of UV degradation or fading. No sanding, scraping or painting required—our windows are virtually maintenance-free.
A Finish That Lasts
While other window materials can expand and contract depending upon the weather, Ultrex Fiberglass expands at virtually the same rate as glass. This makes Marvin Replacement doors resistant to leaks, seal failures and stress cracks that can compromise energy efficiency and long-term performance.
