Who We Are
“Think like a raindrop”—this was the advice often shared by the Master Carpenters who trained us. At Exteriors by Cairn, we bring over 50 years of building experience across Maine, from the rugged coastlines to the quiet inland communities.
Since our early days, we’ve witnessed how construction technology has evolved. It’s no longer just about keeping out the rain and snow—it’s about understanding the home as a complete system. We’ve seen what works and what doesn’t, and we bring that knowledge to every project.
We are a quality- and detail-driven company seeking clients who genuinely care about how the exterior finishes of their home or business come together. Whether it’s a deck, an exterior siding renovation, or a window installation project- we ensure every job is completed efficiently, with an unwavering focus on craftsmanship and detail.
Maine’s seasons can be hard on a structure. We are here to make sure your building stands up to the harsh conditions nature delivers—season after season, year after year.
