We handle basement waterproofing, sump pumps, and drainage systems so you get a dry foundation without worry, typically completed in just a few days.
Family-Owned and Locally Trusted
The floor stays damp after rain. Efflorescence spreads across the walls, and the air carries that musty smell no matter how much you clean. A crack widens near the footer, and the sump pump cycles more often than it used to.
The longer these issues go unaddressed, the worse they become. Structural damage spreads, mold takes hold, and repairs that were manageable grow into expensive projects that affect your home’s value and your family’s comfort.
NH Dry Basement LLC brings proven waterproofing expertise to Concord families and businesses who need lasting moisture control. This family-owned company specializes in basement waterproofing, crawl space drainage, sump pumps, and vapor barrier installation.
Every project starts with a full assessment of your foundation, soil conditions, and drainage patterns. The crew sizes sump systems correctly, places discharge lines where they won’t freeze, and installs vapor barriers that seal out ground moisture for good.
Honest estimates, punctual arrivals, and workmanship you can count on. Your home deserves a dry foundation, and that starts with a contractor who treats it like their own.
Homeowners dealing with foundation leaks get perimeter drainage, sump pumps, and vapor barriers that stop water intrusion for good.
No standing water, no musty smells, and no surprise puddles after heavy rain.
Moisture control stops mold before it starts, so your air stays cleaner.
Storage you can trust, a finished room you actually use, or future resale appeal.
Our basement stayed dry through the last two major storms, something we haven’t been able to say in years. The crew walked us through every step, answered all our questions, and cleaned up after themselves every single day. The new drainage system and sump pump have given us real peace of mind.
They fixed a crawl space drainage problem three other contractors said was too complicated. The difference in our air quality upstairs is noticeable.

With Them
Interior channel and pump systems route water away from your foundation before it can pool on the floor.
Heavy-duty liners lock moisture out of crawl spaces and prevent humidity from rising through dirt floors.
Automatic secondary pumps keep running during power outages so flooding doesn't happen when you're away.
French drains and proper slope divert surface runoff before it reaches foundation walls or window wells.
Commercial-grade units pull moisture from the air so mold doesn't grow on wood framing or stored belongings.
Polyurethane injection and membrane coatings stop water from weeping through foundation cracks and cold joints.
From waterproofing to drainage systems, we handle moisture control across the region. Every job uses materials chosen for New England’s freeze-thaw cycles and heavy spring runoff.
Most basement waterproofing takes one to three days depending on the drainage system type, foundation condition, and whether sump pump installation is included.
Yes. Interior drainage systems with sump pumps handle water intrusion without digging around the foundation, making them faster and less disruptive than exterior work.
A properly installed drainage system with a transferable warranty protects against future intrusion. Any return water usually means a clog or pump failure, both covered under service agreements.
A sump pump actively removes water that collects in the drainage channel. A drain alone relies on gravity, which works only if your lot slopes away.
Wait at least 48 hours for concrete patches to cure and humidity levels to drop below 55 percent before insulating or framing walls.
We deliver reliable basement waterproofing and crawl space solutions that keep Concord homes dry. Reach out to NH Dry Basement LLC for honest service and results that last.
