Basement Waterproofing
We stop water at the source with engineered interior and exterior systems built for New England weather. No more leaks, no more flooding — permanently.
Sump Pump Installation
High-capacity pumps with battery backup keep your basement dry during storms and power outages — exactly when you need them most.
French Drain Systems
The gold standard for foundation water management. Our French drains relieve hydrostatic pressure and channel water safely away from your home.
Foundation Crack Repair
Small cracks become big leaks fast. Our epoxy and polyurethane injection seals cracks permanently — most repairs done the same day.
Crawl Space
Damp, musty crawl space? We seal, encapsulate, and protect it from moisture, pests, and structural damage. Healthier air, drier home, better insulation.
Exterior Waterproofing
Stop water before it ever reaches your foundation. Our exterior membrane system blocks moisture at the source. The most permanent solution for severe water issues.
Interior Waterproofing
The smart choice when exterior work isn't practical. Interior drainage and vapor barriers redirect water to a sump pump and keep your basement dry, all year long.
