Interior Drainage Systems in Edgemoor
When exterior excavation isn't feasible, interior drainage systems provide an effective solution for managing basement leaks. We install perimeter drains along the basement walls, collecting water before it can surface and directing it to a sump pump for removal. This system is less disruptive and can be a cost-effective way to dry out a wet basement.

Emergency Basement Flooding Response in Edgemoor
A burst pipe or a failed sump during a storm can put inches of water on the floor in minutes. Call us and shut off the main water valve if you can do so without risk. We stop the leak, pump out standing water from the plumbing failure and make the system safe. We can also point you to drying and restoration crews when the damage calls for it.
Exterior Waterproofing in Edgemoor, DE
For a more comprehensive solution, we offer exterior waterproofing, which involves excavating around your foundation, applying a waterproof membrane, and installing drainage boards. This method creates an watertight barrier on the outside of your basement walls, providing superior protection against water intrusion. Salt air in coastal parts of Delaware speeds corrosion on outdoor fittings, hose bibs, and exposed metal pipe.

A sudden basement leak can be a crisis, especially during heavy rains. GNV Plumbing provides emergency basement leak repair services in Edgemoor, DE to address urgent water intrusion issues fast.

Clogged Drain Tile Repair in Edgemoor
Interior or exterior drain tile systems can become clogged with sediment or tree roots over time, rendering them ineffective. We focus on diagnosing and clearing blockages in these critical drainage systems, restoring their ability to divert water away from your basement walls and foundation in Edgemoor.
Wall and Slab Seepage Repair in Edgemoor
When water enters through foundation walls or the slab joint, the cause is most often surface water pooling against the house. Sandy soil drains quickly but can shift and settle, which may stress buried sewer lines and water service pipes over time. Dense or saturated soil can hold water near the foundation instead of letting it drain away. We seal penetrations where pipes pass through the wall and can install interior drain channels that carry seepage to a sump. We also suggest grading and gutter changes when outside water is the root cause.
Sump Pump Repair and Installation in Edgemoor, DE
Many basements rely on a sump pit to handle storm runoff and groundwater. After flooding, wells should be tested and septic systems checked before normal use, since floodwater can contaminate both. Pumps from brands like Zoeller, Liberty and Wayne fail most often from a stuck float or a burned-out motor after sitting idle for long stretches. We repair or replace the pump, check the check valve and route the discharge well away from the foundation. A battery backup is worth considering because big storms often knock out power.

Commercial properties in Edgemoor also face the risk of basement leaks, which can damage inventory and equipment and interrupt business operations. GNV Plumbing offers specialized commercial basement leak repair services, providing solid and scalable solutions tailored to the demands of business establishments. We minimize downtime and protect your assets with efficient, professional service.
