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.

My experience withe Cardinal Exteriors - from the owners and management to their team/crew - was wonderful from start to finish. They did a complete renovation of my exterior siding and replacement of all windows. They communicate with professionalism and ease, follow-through is timely, and their crew is extremely hard-working with a strong attention to detail.
