Energy-efficient window replacement for Maine homes
Cardinal Exteriors' window installations combine energy efficiency with architectural beauty. Our experienced team ensures precise fit, proper sealing, and long-term performance in Maine's demanding climate.
Windows rarely fail on their own. Water that gets past a window usually gets past the wall too, so we often pair a window job with new siding installation, and with roofing work where ice damming has already pushed water back into the head trim. Recent window installations across Portland, Yarmouth and Cumberland are in our exterior project gallery.
Vinyl replacement windows are the most common request we see in Greater Portland: they hold a tight seal, clean easily, and keep the project in a predictable range. Wood and clad units from Andersen, Marvin, Pella and Integrity go on houses that need a historic or high-end look. Either way the install is the same job — flashing, shimming and a weather-tight seal — and an owner writes the price after measuring every opening.

We hired Cardinal Exteriors to reside our house and install all new windows, and it was a terrific experience from start to finish! Bob was one of the very best contractors we've ever worked with (and we've worked with many over the years). He was extremely responsive, helpful, respectful of wishes and concerns, and never pressured us in any way.

Bob @ Cardinal Exteriors replace 26 windows and resided our office building in Westbrook in 2025. Being in the construction business, we understand how proposals sometimes come with change orders and surprises if not outlined up front. Bob and his team finished our job on schedule and actually below budget.

CARDINAL EXTERIORS re-shingled my roof. Bob Proved to be Knowledgeable and Trustworthy. He was responsive to my questions and took the time to explain the materials being used and the steps they were taking to weatherproof the roof of my home. The work crew was polite and they cleaned up the job site at the end of each work day.

Frequently Asked Questions
Typical installed cost in Greater Portland is $600–$1,800 per window. Vinyl replacement windows usually land $500–$1,200 each; wood or clad units from brands like Andersen, Marvin and Pella run $1,000–$2,200. A whole-home job of 10–15 windows is often $8,000–$22,000. Size, glass package, and whether siding comes off around the opening move the price. Every job is priced from a free on-site estimate.
Most whole-home window replacements take two to five days on site once the units arrive. A handful of openings can be a single day. Lead time on the windows themselves is usually a few weeks. An owner will put dates on the written proposal.
We provide complete window installation, replacement, and upgrade services including vinyl replacement windows, double hung, casement, picture, bay, sliding, and awning windows. We work with premium brands like Andersen, Marvin, Pella, and Integrity to deliver energy-efficient, durable window systems.
Maine's harsh winters and coastal weather demand a weather-tight fit. Improper sealing leads to air leaks, condensation, energy loss, and structural damage. Our master installers handle flashing, shimming and sealing so the unit lasts in a freeze-thaw climate.
Financing is available. Ask about payment options when you request your estimate. There is no published rebate figure on this site; Efficiency Maine and manufacturer programs change, and we confirm what applies to your house during the visit.
Use the form on this page or call. We assess the current windows, discuss your goals, review vinyl and wood-clad options, and write a detailed quote. We can also show you similar installations nearby.
