Expert PEX Pipe Installation and Whole-Home Repiping in Dover, DE

Some homes from the late 1970s through the mid 1990s contain polybutylene pipe, which is best replaced before it fails. When copper lines under a slab develop pinhole leaks, we reroute new PEX through attics and walls. You get a reliable system without tearing up your slab.

Citywide Coverage
We install PEX in homes across Dover, from 1970s ranch houses with galvanized lines to 1990s builds with aging polybutylene. Every repipe is planned around your home's layout and attic access.
Experienced Team
Our plumbers have completed many whole-home repipes and know how to route PEX through tight attics, around ductwork and through finished walls. They plan the layout before opening any drywall.
Safety-First Approach
PEX must be kept out of direct sunlight and away from heat sources like water heater flues, so we sleeve and route it carefully in attics. We also follow distance requirements from the water heater using listed transition fittings.
