Energy Efficiency Audits & Contracting in Maine

Windows & Doors

Ensuring that your Midcoast Maine or Portland area home is comfortable, durable and valuable depends on having beautiful and functional windows and doors. Evergreen Windows & Doors installs new replacement windows and doors from the Marvin Integrity line, with our signature attention to detail.

Quality Replacement Windows & Doors

Evergreen has chosen the highest quality products to ensure that you’re satisfied with the benefits that new windows and doors can bring to your home. Integrity products from Marvin are made with Ultrex fiberglass, which prioritizes strength, energy efficiency and sustainability.

Sustainable & Durable

Since Ultrex is made from silica sand, a safe and abundant resource, it is a sustainable material choice. The process of transforming sand into fiberglass produces a strong and resilient product that has a 38% longer useful life than vinyl.


Marvin Integrity products have very low thermal expansion rates. So your new windows and doors will be resistant to leaks, seal failures and stress cracks, meaning that performance and efficiency are never compromised. In addition, since Ultrex fiberglass is extremely durable it won’t fade or be easily marred, scratched or dented, offering you peace of mind about your investment.

Energy Efficient Windows & Doors

At Evergreen, our roots are in home performance, that’s why we’re dedicated to ensuring that your new windows or doors not only look great, but that they’re also helping your home. Many options from Integrity by Marvin are even ENERGY STAR qualified.


By installing these high-performance products with great care, new doors or windows can help to decrease your utility bills, reduce your home’s carbon footprint and make your home more comfortable year-round.
