New decks, not patch jobs
Cardinal Exteriors builds new decks and full deck replacements. Partners Michael McCullum and Robert Milliken lead every project: new footings, new framing, new decking, railings and stairs, built to carry Maine snow and handle freeze-thaw.
We do not do board-by-board repairs or staining. If your old deck is failing, we take it off and build it new. Planning more work on the house at the same time? We also handle siding replacement, replacement windows and roof replacement, and completed exterior work is in our project gallery.

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.

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.

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.
