Basement Waterproofing in Greenwich, CT

We install a lasting basement system that quietly drains groundwater before it rises, keeping your home dry, clean, and healthy—without the headaches of temporary fixes or high-maintenance add-ons.

Signs it's time to act:

• Water on the basement floor after storms
• Musty smells or mold starting to appear
• Wall stains, peeling paint, or wet corners
• Previous fixes that didn’t work or wore out

We transform dirt-floored crawl spaces into clean, dry, usable areas with a sealed concrete layer that keeps out moisture for good—no more mold, pests, or soggy insulation. No plastic sheets. No constant dehumidifiers.

Why Greenwich homeowners call us:

• Strange smells rising through the floor
• Visible moisture or condensation in the crawl space
• Animals or insects getting inside
• Wasted space that could be used for storage

Your waterproofing system is only as good as your sump pump. We install professional-grade pumps that move water fast and keep your basement dry—even if the power goes out. Optional Wi-Fi backup systems alert you instantly.

Common issues we solve:

• Basement flooding when storms hit
• Old or loud pumps that don't work well
• No battery backup during outages
• Frozen or clogged outdoor discharge lines

Cracks let water in. Our proven repair method seals the crack and reinforces the surrounding wall—giving you a dry, stable foundation you can count on, without messy caulk or failed patches.

Common problems we fix:

• Cracks growing over time or letting water in
• Failed repairs that never lasted
• Gaps around windows or corners
• Moisture streaks or wall discoloration
