Verified reviews from homeowners across Connecticut
“Our Fairfield basement had been leaking for years. Connecticut Basements installed an interior drainage system and sump pump — the basement has been bone dry through two nor'easters since. Worth every penny.”
“Found a horizontal crack running across our Greenwich foundation wall. The team installed carbon fiber straps and sealed the crack with epoxy injection. Structural engineer confirmed the repair is solid. Very professional crew.”
“After our old sump pump failed during a storm, Connecticut Basements installed a new primary pump with a battery backup system. They also added a water alarm. Peace of mind during heavy rain in Stamford.”
“Turned our unfinished West Hartford basement into a family room with a wet bar. Connecticut Basements handled everything — framing, drywall, flooring, drop ceiling, egress window. Came in on budget and the quality is outstanding.”
“Our Trumbull crawl space was damp and musty. They encapsulated the entire space with a heavy-duty vapor barrier, installed a dehumidifier, and sealed the vents. Humidity dropped from 80% to 45%. No more mold smell.”
“Water was pooling along the foundation of our Norwalk home every spring. Connecticut Basements installed an interior French drain tied to a new sump pump. The system works exactly as they described — no more standing water.”
