Trusted Mill Valley Sump Pump Experts

Protecting Mill Valley Basements & Crawl Spaces from Water Intrusion

In Mill Valley, seasonal rains, high groundwater, and irrigation runoff can push moisture into basements and
crawl spaces. Left unchecked, excess water leads to mold growth, warped flooring, foundation damage, and
unhealthy indoor air. A properly installed sump pump system collects water at the lowest point and discharges
it safely away from the structure. Our licensed team evaluates soil conditions, drainage paths, and access
points to design a solution that fits your home. We start by identifying where water enters: perimeter
foundation seams, slab cracks, or poorly graded landscaping. Then we build a plan that may include a gravel
trench, perforated drain tile, a durable basin with a gas‑tight lid, and a dependable pump sized for your
expected inflow. For homes in Mill Valley with frequent storms or high water tables, we recommend heavy‑duty
pumps with float switches that resist debris. Check valves prevent backflow, and dedicated circuits reduce
nuisance trips. Moisture control is about more than hardware. We seal penetrations, improve downspout
routing, and suggest vapor barriers for crawl spaces. Where electrical outlets are limited, we coordinate with
your electrician for safe, code‑compliant power. Before we leave, we test the system under load and walk you
through operation and basic maintenance so you feel confident when the rain comes.
