Blackmon Plumbing is a trusted, family-owned plumbing company proudly serving Baytown, Houston, and surrounding areas including North Houston and The Woodlands. Since 2007, we've delivered expert residential and commercial plumbing services—from drain and sewer repair to water heaters, gas lines, whole-house generators, and water treatment systems. Our experienced, licensed plumbers are known for quality work, honest pricing, and outstanding customer care.
If you are calling a plumber every six months to clear backups, or if your home smells like sewage when it rains, a “repair” is no longer enough. You likely have a systemic failure—whether it’s rotting Cast Iron under your slab or a yard line crushed by tree roots.
At Blackmon Plumbing, we specialize in Whole-Home Sewer Replacement. We don’t just patch the symptom; we remove the dying infrastructure and install a brand-new, code-compliant PVC system.
Because we dispatch Mobile Warehouses equipped with heavy-duty excavation tools and bedding materials, we manage the entire project—from permitting to backfill—without the delays of smaller contractors.
A full sewer replacement is a major construction project. It requires more than just a wrench. Our fleet arrives ready for heavy lifting.
Replacing a sewer line is an art. If the “slope” (angle) is off by even a fraction of an inch, waste will stall and clog. We hold Master Plumber License MPL-38162, and we get the math right.
Before we dig, we map the elevation from your home’s exit point to the city tap. We calculate the exact “fall” needed (typically 1/8 to 1/4 inch per foot) to ensure self-cleaning velocity.
We do not just lay pipe on the dirt. We install a “bed” of sand or crushed stone. This supports the pipe evenly so it cannot settle or warp over time—preventing the dreaded “belly.”
Proper bedding is the difference between a 50-year system and one that fails in 10 years.
We fill the new system with water (Hydro-Static Test) to prove it is watertight. Only after the City Inspector passes our work do we backfill and compact the soil.
We know that digging up a sewer line is invasive. That is why our job isn’t done when the pipe is covered.
If your Houston home was built before 1980, you likely have Cast Iron drains. These pipes have a lifespan of about 40–50 years. We are now past that deadline.
The Solution: No amount of “cleaning” can fix rot. The only solution is replacing the iron with smooth PVC.
Why upgrade to PVC? Because it is the only material designed to outlast the mortgage on your home.
These are Cast Iron strongholds. We perform full under-slab replacements here to eliminate roach infestations and chronic backups caused by channel rot.
Roots destroy clay pipes here. Once roots have shattered the pipe every few feet, spot repairs are useless. We replace the entire yard line with seamless PVC.
Soil Shifting causes “back-fall” (water flowing the wrong way). We replace the line and re-bed it with sand to correct the angle.
A full replacement is a major investment in your home’s value.
A: Typically 1–2 days. We aim to have your water back on the same evening.
A: We treat your yard with respect. We lay down plywood to protect grass from heavy equipment and hand-dig around sensitive flower beds.
A: Code requires them, but they also save you money later. They allow a snake to go both ways (toward the street and toward the house) without removing a toilet.
Competitors may try to sell you a “Pipe Liner” (a resin sock inserted into the old pipe). We refuse to do this.
Stop paying for temporary fixes. Upgrade to a modern sewer system with Blackmon Plumbing.
