Owner-Led. Quality-Focused.

About Us

We specialize in residential asphalt services with a focus on quality, consistency, and the kind of care only an owner-led crew delivers.

The McMahon Legacy

Built on Hard Work. Backed by 13+ Years of Experience.

Back in 2010, Thomas McMahon set out with a simple mission: deliver top-quality asphalt maintenance with integrity and precision. Armed with nothing but a hand brush, a commitment to excellence, and the promise that “If my name’s on it, I’ll be there to make it right,” he built McMahon Seal Coating & Services LLC from the ground up.

Today, that same dedication fuels every project we take on—from protecting residential driveways in Salem, NH to restoring high-traffic commercial lots in Manchester, NH. No matter the job, our goal remains the same: superior craftsmanship, long-lasting results, and customer-first service.

Local Service You Can Count On

We’re proud to serve homeowners and property managers across Derry, Londonderry, Manchester, Chester, Windham, Salem, and surrounding areas — delivering reliable, professional work that lasts. Whether it’s seal coating, crack filling, asphalt repair, or seasonal cleanups, we take pride in the details. Every job is hand-applied, never rushed, and overseen by the owner himself. Because when your name is on the truck, the results matter.
