A sump pump alone does not keep a basement dry. It only handles water that already made it to the pit. A full system, the Forever Dry System, catches water at the floor wall joint with a perimeter drain, moves it to the pump, and seals the walls, so water never spreads across the floor. The pump is one part, not the whole answer.
Many New Hampshire homeowners think installing a sump pump is all they need to keep their basement dry. While it can handle water that collects directly under the pump, this reactive approach leaves most basement leaks unaddressed.
In towns like Exeter, Kingston, Hampton, Dover, Stratham, Portsmouth, and Brentwood, older homes face seasonal frost heaves, shifting soils, and high groundwater levels, which create multiple entry points for water. The footing-wall joint, where your foundation wall meets the concrete footing, is the primary area where water enters basements. A sump pump alone does not address this critical zone, leaving homeowners vulnerable to leaks, mold, and structural damage.
- Sump Pump: Limited Protection
A standalone sump pump:
- Only captures water directly under the pump, typically from a rising water table.
- Does not prevent water from seeping in along the footing-wall joint, where most water enters in New England homes.
- Cannot stop wall moisture, condensation, or hydrostatic pressure from building up along perimeter walls.
- Depends on electricity, so power outages can leave your basement unprotected during storms.
In other words, a sump pump is reactive, it only removes water after it has already become a problem.
- Full Basement Waterproofing System: Comprehensive Protection
A professional waterproofing system, like our Forever Dry System, addresses the real sources of basement water:
- Footing-wall joint protection: Patented drainage channels capture water where it first enters the basement.
- Wall and floor moisture management: Sealed vapor barriers funnel all water into the drainage system.
- High-end sump pumps with battery backup: Remove water reliably even during power outages.
- Radon-safe or compatible designs: Maintain ventilation if a radon system is installed.
- Long-term reliability: Handles frost heaves, soil shifts, and New England precipitation cycles.
By targeting both surface seepage and rising groundwater, a full system prevents leaks before they start, rather than just reacting to them.

Frequently asked questions
Is a sump pump enough on its own?
No. A bare pump only moves water that has already reached the pit, so water still comes in at the walls and the floor wall joint and spreads before it ever gets there. You need something to catch it first.
What is in a full waterproofing system?
Our Forever Dry System is a full perimeter drain, a sump pump for about every 120 feet of drain, a vapor barrier on the walls, and a dehumidifier. The drain catches the water, the pump sends it out, and the barrier keeps the walls dry.
Do I need a battery backup?
We recommend it. The power tends to go out in the same storm that floods a basement, and a plug-in pump is useless without power, so a battery backup keeps it running when it matters most.
