Hot Rubberized Crack Sealing
Unsealed asphalt cracks invite water to seep beneath the surface, where winter freeze-thaw cycles expand the gaps and destroy the base foundation. We clean open cracks with pressurized air and wire brushes before injecting a commercial-grade hot rubber joint sealant. This rubberized compound remains flexible through extreme hot and cold weather shifts, sealing out water and extending asphalt life.
Pothole Repair & Patching
Potholes are hazardous to vehicles and pedestrians alike, creating serious liability risks for property owners. Our team performs durable pothole repairs by cutting away broken, compromised material, prepping the base, and filling the section with high-grade hot or cold asphalt mix. We compact the patch flush with your existing pavement to deliver a safe, level driving surface.
Parking Lot Line Striping & Marking
Clear, bright line striping improves traffic safety, optimizes space usage, and ensures ADA accessibility compliance for your business. Following fresh sealcoating or to refresh faded markings, we apply traffic-grade paint for crisp lines, directional arrows, fire lanes, and handicap stalls.
Surface Preparation & Oil Spot Priming
Proper preparation makes or breaks a sealcoating job. Before applying any sealer, we thoroughly clean the surface using high-powered blowers and industrial brooms. Any fluid leaks or motor oil stains are treated with specialty oil-spot primers to ensure maximum sealer adhesion and prevent chemical bleeding.

“Transformed Our Driveway!”
“Our driveway was starting to look grey, dry, and pitted after a couple of brutal New Hampshire winters. D&M came out, filled all the expanding cracks with hot rubber, and applied a thick, clean sealcoat. The edges along our stone walkway and garage door are spotless—no overspray anywhere. Highly recommend!”

“Professional, Prompt, and Fair Pricing”
“DM made the process completely painless. They provided a quick quote, explained why we needed to wait for the proper ground temperature for ideal adhesion, and showed up right on time. The deep black finish brought back our home’s curb appeal immediately.”
– Taylor Johnson, Swanzey, NH
“We had several major stress cracks from heavy delivery trucks and winter snowplowing. The crew thoroughly prepped the surface, cleaned out all the dirt, and sealed everything up tight. Water now beads right off the driveway instead of soaking in. We won’t use anyone else!”
Casey Williams , Keene, NH
“Managing a commercial lot means keeping disruptions to a minimum for our tenants. D&M worked around our business hours, completing the crack filling, sealcoating, and line striping over the weekend. The parking lot looks brand new, and the fresh lines made our layout much safer.”
