A drier basement through heavy rain and snowmelt
Seasonal snowmelt, prolonged rain and high groundwater can make a basement difficult to use and leave homeowners checking the floor whenever a storm arrives. B‑Dry installs an interior waterproofing plan designed around the conditions in your home.

What to expect
A straightforward process from the first visit through installation.
Evaluate the basement
We inspect the water entry points, drainage conditions and pumping needs.
Receive a written quote
You receive a clear plan and price based on the work recommended for your basement.
Install the system
Our crew installs the approved system and reviews the completed work with you.
Lifetime protection for the installed drainage system
The installed B‑Dry interior French drain system is backed by a transferable lifetime warranty. That warranty applies to the portion of the B‑Dry drainage system installed in your home—even when the project is a partial system.
Pumps, battery backups, dehumidifiers and discharge components have their own separate warranty terms.
The important distinction
Warranty—not a blanket guarantee against every possible source of water.
Your written warranty explains exactly what is covered by the installed B‑Dry system.
Southern New Hampshire basement waterproofing FAQs
Do you provide free basement waterproofing quotes in Southern New Hampshire?
Yes. B‑Dry can evaluate the basement, explain the recommended scope and provide a written quote.
Does every home need a full perimeter system?
No. The recommended scope depends on where water is entering and the conditions in the basement. Partial drainage systems still receive warranty coverage for the installed portion.

No. B‑Dry specializes in interior basement waterproofing, French drain systems, sump equipment and moisture control. We do not provide basement remodeling, refinishing, water cleanup or mold remediation.
