Not General Plumbers.
Underground Specialists.
MasterTex Drain & Slab Authority was built to solve the problems most plumbing companies aren't equipped to handle — sewer failures, under-slab breakdowns, and cast iron deterioration.
Specialized Underground Focus
We don't do faucets, water heaters, or general plumbing. Every resource is dedicated to diagnosing and repairing sewer, drain, and under-slab failures.
Hybrid General Contractor Model
Most plumbing companies sub out tunneling, concrete work, and restoration. Each subcontractor adds markup. Our model keeps everything under one roof — saving homeowners thousands.
Cost Savings Through In-House Execution
By owning the full scope — plumbing, tunneling, concrete, and restoration — we eliminate middleman markups that typically inflate project costs by 30–50%.
Long-Term Repair Philosophy
We don't sell band-aids. Every repair recommendation is designed to be permanent. If a pipe needs replacement, we say so. If a spot repair will last 20 years, we say that too.
