About San Leon
What we see in San Leon homes.
San Leon is a Galveston County community we’ve worked in since the early 2000s. The neighborhood is a mix of older slab-on-grade homes from the ’70s and ’80s and newer construction — which means our calls here range from slab leak diagnostics to brand-new tankless installations.
The most common things we fix in San Leon: original-builder polybutylene pipe still in service, water heaters reaching the end of their 12-year lifespan, and sewer lines that have shifted with the clay soil. We bring the right tools for all three.

From San Leon homeowners
Your San Leon neighbors trust Alliance
“Kelly’s crew arrived 30 minutes after I called about no hot water on a Sunday morning. They explained every option, gave a fixed price, and had a new tankless running by dinner. I haven’t run out of hot water since.”
“Our water bill doubled overnight. Alliance found the slab leak in 20 minutes with their listening equipment, gave us two options to fix it, and didn’t pressure us into the expensive one. Top to bottom professional.”
“Hired Alliance for the plumbing on a full primary bath remodel. They worked perfectly alongside our contractor, kept the site spotless, and the trim-out is beautiful. Will absolutely use them again on the kitchen.”
