The McMahon Legacy

From Driveway Repairs to Commercial Excellence

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 to restoring high-traffic commercial lots in Manchester. No matter the job, our goal remains the same: superior craftsmanship, long-lasting results, and customer-first service.

What Our Customers Say

Deb Martel
Highly recommend. He was always responsive; an almost instant response to my request for an estimate. Estimate done as promised and sealcoating followed. Excellent, excellent service, attention to detail, extra little steps to make sure it is done correctly. Super customer service, super job. He will be back when my driveway needs attention again.
Christopher Paul Langlois
TJ is the best he made my crap driveway Look brand new! Thank you for all your hard work.
Matt Kirby
Had them come out to look at my driveway, which needed sealcoasting and blacktop repair. Setting an appointment was easy, and they completed the work efficiently and with professionalism. Would recommend 100%, and will usw them again when the time comes. The driveway looks amazing.
Paige Fowler
This is the place to go for sealing your driveway to perfection! Communication was great. They were very prompt with getting me an estimate and were able to complete the job soon after. We wanted the coating to be hand applied not sprayed and they went above and beyond to meet our needs. The results look amazing and is exactly what we had hoped for!

Tom did an absolutely wonderful job filling a ton of cracks and sealing our driveway. You can see how much he cares about his quality of work by his focus when working. Tom also did a great job fixing our crumbling concrete pad that our front stairs rest on.
