Serving Sussex Since 1981
New Subdivisions and Country Homes
Much of Sussex grew in the 1990s and 2000s, with subdivisions of two-story homes and large poured-concrete basements. Around the village, the Town of Lisbon mixes newer homes on bigger lots with older farmhouses that sit on stone or block foundations.
Newer homes often have the problems people don't expect: poured walls that crack and leak, sump pumps that run constantly and window wells that fill up. Older country homes deal with aging stone walls and drainage that was never designed for a finished basement.
We'll look at your home inside and out, explain what's causing the problem and give you a written estimate for the fix.

What We See in Sussex
Common Basement Problems in Sussex Homes

Wet springs and clay soil keep sump pumps busy, and they wear out.

Cracks and tie-rods in newer walls can leak once the ground is saturated.

Farmhouses in Lisbon often sit on stone walls that seep through old mortar.

How We Help Sussex Homeowners
Sump PumpsSump Pumps & Battery Backups
A reliable sump system is critical in Sussex and Lisbon. We install properly sized pumps and battery backups.
For very wet lots, a second pump adds capacity during heavy storms.
We test the system before we leave and walk you through how it works, so you know your Sussex basement is protected the next time a storm rolls through.
Sump Pump Details
Wall LeaksLeaking Walls
Leaking cracks and tie-rods in poured walls are sealed from inside with injection.
Older stone walls get drainage plus repointing where the mortar has failed.
We'll show you exactly where the water is getting through and explain why we're recommending one repair over another, so there are no surprises on your Sussex project.
Wall Leak Repair
WindowsEgress Windows & Window Wells
Window wells without real drains are a common leak point. We rebuild them with drains and covers.
We also install egress windows for basement bedrooms in newer homes.
Every window and well we install is set to drain properly, so it adds light and safety to your Sussex basement without adding a new leak.
Egress Windows
SeepageFloor & Wall Seepage
Seepage along the base of the walls is handled with interior drain tile that relieves pressure under the floor.
Only a narrow strip is opened and patched.
Because the fix relieves the pressure instead of just sealing the surface, the water doesn't simply move to a new spot. Most Sussex homeowners notice the difference after the very next storm.

Why does my sump pump run so much?
Clay soil and wet springs send a lot of groundwater to the pit.
