We handle basement waterproofing, drainage systems, and sump pumps so you get a dry foundation without mold or water damage, often within days.
Trusted by Local Families
You notice the damp smell, the puddles forming after every storm, the watermarks climbing your foundation walls. Maybe you’ve tried sealants or running fans, but the water keeps finding its way back in.
The longer it goes unresolved, the worse it becomes. Mold starts spreading. Your foundation weakens. The repairs cost more. And the space you should be able to use turns into a problem that keeps you up at night.
NH Dry Basement LLC specializes in basement waterproofing, crawl space drainage, and vapor barrier installation for Rochester families and businesses who need reliable moisture control. Since opening, the team has focused on sump pumps, battery backups, dehumidification, and ventilation systems that keep basements dry year-round.
Every project starts with a thorough inspection of drainage systems, foundation walls, and crawl space conditions. The crew handles concrete slabs, demo and removal, and mold prevention with the same attention to detail, using proven techniques for vapor barriers, perimeter drains, and sealed encapsulation.
As a family-owned business, NH Dry Basement shows up on time, communicates honestly, and stands behind every install. Your home deserves a foundation that stays dry, healthy, and built to last.
Homeowners dealing with foundation leaks get perimeter drainage, sump pumps, and vapor barriers that stop water intrusion for good.
No more pooling water or damp corners after heavy rain or spring melt.
Less humidity means fewer musty odors and reduced mold risk throughout your home.
Proper drainage and waterproofing stop hydrostatic pressure before it cracks walls or damages concrete.
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.

Ground slopes correctly away from foundation walls so surface water never pools against your basement.
Interior drainage channels tie into sump systems that route groundwater out before it surfaces on your floor.
Crawl space air movement removes moisture before condensation forms on joists and causes mold or rot.
Heavy-duty polyethylene sheets overlap and seal at seams so vapor never migrates through the crawl space floor.
Submersible sump pumps with battery backup remove water during storms and power outages without missing a cycle.
Crews contain dust and debris during concrete work so your living space stays clean throughout the entire project.
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 jobs wrap up in two to three days depending on basement size, sump pump needs, and drainage channel length. Same-day work is possible for smaller sump installs when conditions allow.
Waterproofing stops future water entry, but existing odor usually means mold or mildew already present. Proper ventilation and dehumidification after the install help clear the air over time.
Yes. Once the system cures and humidity drops, finishing proceeds as planned. Wait a few weeks to confirm everything stays dry before installing drywall or flooring over the new work.
Honest contractors stand behind drainage and sump systems with transferable coverage. If water enters through the protected area after installation, the crew returns to diagnose and repair at no charge.
Minor cracks get sealed as part of the scope. Larger structural issues are explained on the spot with repair options and costs laid out before any extra work begins.
