Overview
About McMahon Seal Coating And Services LLC
McMahon Seal Coating & Services LLC is an owner-operated asphalt maintenance company based on Bypass 28 in Derry, New Hampshire. Thomas McMahon started the business in 2010, and the company says he oversees each job himself and does not use subcontractors.
The core of the work is driveway sealcoating, applied by hand with a brush rather than sprayed, which the company presents as its signature method. Cracks are cleaned out and filled with hot rubber sealant before coating, and the company also repairs cracked, crumbling and potholed asphalt, blending each patch into the surrounding surface. Seasonal property cleanups round out the maintenance side.
Most of its history is in residential driveways, though it also works on commercial lots, with Manchester given as an example. Beyond sealing and repair, the company lists line striping, curbing, sidewalks and drainage adjustments among the work it takes on.
It serves homeowners and property managers in Salem, Windham, Chester, Manchester, Londonderry and its home base of Derry, and schedules free estimates by phone or through the form on its website.
