Basement Flooding or Dampness?

Our Stamford basement waterproofing system is installed below the floor to intercept groundwater from cold joints and rising pressure. It quietly directs water to a sump pump and discharges it away from your home—without the need for annual maintenance.

Common basement problems we fix:

Wall-floor joint seepage: caused by groundwater at cold joints
Recurring basement water after storms: a sign of rising water
Musty smells and visible mold: high indoor humidity levels
Old or failed waterproofing systems: inferior or shallow methods

Does Your Crawl Space Stay Damp?

Our SuperCrete Crawl Space System creates a seamless concrete barrier over dirt floors, locking out ground moisture and eliminating the need for vapor barriers or dehumidifiers. It’s clean, dry, and built for long-term performance.

Conditions we eliminate in Stamford crawl spaces:

Moisture and mildew: caused by exposed soil
Insulation falling or rotting: signs of long-term humidity
Pest intrusion: rodents thrive in damp crawl spaces
Lost storage opportunity: we reclaim your space

Is Your Sump Pump Ready for the Next Nor’easter?

We install sump pump systems with cast-iron components, high-water alarms, and optional Wi-Fi battery backups. Built for Connecticut storms, our system keeps working—even when the power goes out.

Typical sump pump problems we solve:

No battery backup: leaves your home vulnerable in outages
Noisy or short-cycling pumps: signs of improper installation
Frozen or blocked discharge lines: common in New England winters
Flooding despite a working pump: poor system design

Worried About Foundation Cracks?

We seal foundation cracks with flexible polyurethane injections and overlay the area with SuperCrete for strength and waterproofing. It’s not a patch—it’s a permanent fix that blends strength with flexibility.

We repair Stamford foundation issues like:

Thin vertical or horizontal cracks: signs of settlement or stress
Water seepage through concrete: damaging to air quality and structure
Flaking surface patches: failed previous repairs
Widening cracks over time: need structural attention
