Sump Pump Installation & Repair in Greenwich, CT – Basement & Outdoor Systems

Sump pumps are a critical defense against basement flooding in Greenwich CT. With our region’s unpredictable storms and rising groundwater levels, even a small leak can quickly turn into a costly disaster. A properly sized and installed sump pump system intercepts water before it reaches your foundation, preventing mold, mildew, and structural damage. Our licensed technicians assess factors like soil saturation, basement square footage, and peak rainfall to recommend powerful, high-capacity pumps that handle 2,400–3,600 gallons per hour. Each system includes heavy-duty PVC discharge lines with check valves and pit coverings to ensure long-term reliability and compliance with Greenwich’s stormwater guidelines.

Repairing or replacing a sump pump is not a DIY job — leave it to the experts. Incorrect installation, improper float switch positioning, or mismatched timers can cause your system to fail when you need it most. Our team evaluates every aspect of your existing system — from float activation range to battery backup integration and timed water level control — and performs precise troubleshooting. We replace worn components like pumps, backup batteries, and discharge check valves, or recommend full replacements when needed. You’ll also receive a maintenance plan with seasonal check-ups, cleaning tips, and parts inspection. When floods threaten your home, you want a trusted Greenwich sump pump contractor like CT Stormwater who ensures peak performance every time.
