Plumbing Services in Katy, TX | Done in One Trip
Expert Plumbing Services in Katy | Dispatched Nearby
Blackmon Plumbing provides Master-level plumbing services to Katy and the surrounding communities. We are a family-owned company, founded in 2007, with a unique approach to service: The Mobile Warehouse.
While our headquarters is in Baytown, we do not operate out of small pickup trucks that require constant trips back to the shop. Instead, our fleet of large, fully stocked box vans is actively circulating through Katy, Cypress, and Sugar Land daily. We carry thousands of parts, fixtures, and specialty tools on every truck. This allows us to fix your plumbing emergency on the first visit, without the “waiting on parts” delays common with other contractors.

Common Plumbing Issues We Fix in Katy
As part of Zone 2 (West), Katy homeowners deal with specific plumbing challenges caused by the shifting clay belt.
Slab Leak Detection & Repair
The heavy clay soil in Katy expands and contracts with Texas weather, putting immense pressure on foundations and underground pipes. This often leads to “slab leaks” that go unnoticed until your water bill spikes. We specialize in Static Isolation Testing to pinpoint these leaks under your slab without guessing.
PEX Repiping
Many homes in this area face pipe failure (shearing) due to intense ground movement. We modernize homes with flexible PEX piping that can withstand shifting soil far better than rigid copper or galvanized steel.
Serving Neighborhoods Across Katy
We don’t just drive past Katy on the highway; we work inside its neighborhoods every day. Our technicians are likely navigating local roads right now, fully stocked to handle your plumbing needs.
