We handle basement waterproofing, drainage systems, and sump pumps so you get a dry foundation without constant worry, often within just a few days.
Trusted by Local Families
You see the damp spots spreading across the floor, the musty smell that lingers after every storm, the cracks where water keeps pushing through. Small leaks turn into bigger problems when walls stay wet and foundation damage starts to show.
Waiting only raises the cost. Mold takes hold. Structural repairs multiply. And the space you planned to finish becomes the one part of your home you avoid.
NH Dry Basement LLC brings real basement and crawl space solutions to Northwood families and businesses. Built around family values, this small-town team handles every project with the care and attention you’d expect from a neighbor, not a faceless contractor.
Since day one, the focus has been on drainage systems, sump pumps, vapor barriers, and dehumidification work that stops water before it becomes a problem. Every install is done by experienced hands who understand concrete slabs, battery backups, and mold prevention from the ground up.
Honest pricing, punctual crews, and work that stands the test of time define the way this team operates. Your home deserves a dry, healthy foundation you can count on for decades.
Homeowners dealing with foundation leaks get perimeter drainage, sump pumps, and vapor barriers that stop water intrusion for good.
Waterproofing that keeps your basement and crawl space dry through spring runoff, summer storms, and winter thaw cycles.
Drainage that relieves hydrostatic pressure before it cracks walls, shifts footings, or damages your home's structure.
Vapor barriers and dehumidification that stop musty smells, mold spores, and excess humidity from reaching your upstairs rooms.
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.

Correct grading and channel positioning direct water away from footers so pressure never builds below the slab.
Cast-iron pumps and oversized discharge lines handle heavy rainfall without overload or mechanical failure during storms.
Overlapped seams and anchor strips lock out ground moisture so crawl spaces stay dry year after year.
Thick polyethylene liners resist puncture and UV damage, protecting foundation walls for decades without replacement needs.
Deep-cycle battery systems activate during outages to keep basements protected when main power fails during flooding events.
Tools and debris are cleared at the end of each visit so your home stays orderly throughout the installation.
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 waterproofing jobs finish in one to three days depending on system type, space size, and whether concrete work is needed. Sump pump installs and vapor barriers go faster than full perimeter drainage. We walk you through the timeline before we start.
Yes. We excavate a pit, install a liner, set the pump and discharge line, and test everything before cleanup. If your basement or crawl space is prone to standing water, we size the pump and backup system to match your property’s drainage load.
We explain what we see, show you photos if needed, and walk through your options for repair or remediation. Unexpected issues like rot or mold get addressed before we seal anything up so the fix holds long term and your space stays dry.
Yes. Crawl space drainage often ties into the same sump basin, and a vapor barrier seals moisture coming up from below. Combining both services gives you complete protection from ground water and humidity so your home stays structurally sound.
Once a year at minimum. Check the charge level, clean the terminals, test the float switch, and confirm the pump kicks on during a simulated power outage. Regular checks catch weak batteries and worn switches before the next heavy rain hits.
