Waterproofing for Older Delaware Homes in Hockessin, DE

Many older homes in Hockessin and across Delaware were not built with modern waterproofing techniques, making them more vulnerable to basement leaks. Some homes from the late 1970s through the mid 1990s contain polybutylene pipe, which is best replaced before it fails. GNV Plumbing focuses on retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.

Interior Drainage Systems in Hockessin

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.

Foundation Crack Repair in Hockessin

Foundation cracks are a common entry point for basement water leaks, especially in homes built on soil that swells and shrinks. Much of Delaware sits on sandy coastal plain soil with a high water table, which affects slab, crawlspace, and septic design. We utilize epoxy and polyurethane injection techniques to seal these cracks, preventing water infiltration and reinforcing your foundation. Our methods are tailored to the specific type and size of the crack, ensuring a durable repair.

Floor Drain and Backwater Valve Repair in Hockessin

A basement floor drain that backs up during heavy use or a storm usually points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced easily.

Exterior Waterproofing in Hockessin, DE

For a more complete solution, we offer exterior waterproofing, which involves excavating around your foundation, applying a waterproof membrane, and installing drainage boards. This method creates an impermeable barrier on the outside of your basement walls, providing strong protection against water intrusion. Humidity causes condensation on cold water lines and toilet tanks, which can quietly damage floors and encourage mold.
