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 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 requiredour 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.
