Houston is hard on sewer lines. Gumbo clay that swells and shrinks, a water table that sits high after every heavy rain, and housing stock spanning a century of pipe materials all add up to drain and sewer problems that show up sooner and hit harder than they do elsewhere in Texas.
Molberg Plumbing handles the full range for Houston homeowners, from a kitchen line that’s been slowing down for months to a collapsed main that needs to come out. Licensed plumbers, a real diagnosis, and a price you hear before we start.

Houston drain lines take a beating. Humidity, heavy household use, and pipe that’s frequently older than the people living above it all shorten the interval between clogs. Grease hardens against the pipe wall. Hair and soap film build a mat in bath lines. Food solids collect in any spot where flow slows down.
Chemical drain openers are particularly unhelpful here. They open a narrow channel, leave the accumulated buildup on the pipe wall, and on the cast iron that’s common throughout older Houston neighborhoods, repeated use accelerates corrosion that’s already underway.
We clear drains with commercial cable machines and jetting equipment sized to the line, then confirm full flow before leaving. If the same drain has clogged three times this year, we’ll tell you what’s actually driving that instead of putting you on a cleaning schedule.
The main sewer line carries everything the house produces. When buildup, roots, or a settled section reduce its capacity, the symptoms surface at the lowest fixture and work up from there.
Sewer cleaning clears the restriction and, paired with a camera inspection, tells us the real condition of the pipe. In Houston that second part carries extra weight, because a line that cleans up fine may still have offset joints or a belly holding water that will bring you right back to the same problem in a few months.
You’ll get an explanation of the findings and a quote before any equipment runs.
Hydro jetting is the most thorough cleaning a residential line can get. High-pressure water through a specialized nozzle strips grease, scale, sludge, and root hairs off the entire pipe wall and flushes the material out of the system instead of pushing it further down the line.
Cabling bores through a clog. Jetting removes what caused it. On a Houston kitchen line where years of grease have narrowed a four inch pipe to something closer to two, that difference determines whether the fix lasts three weeks or three years.
We recommend jetting for recurring clogs, heavy grease lines, and any sewer that keeps needing to be cabled. A camera inspection comes first, since a badly corroded cast iron line needs repair rather than pressure.

The city’s soil, water table, and pipe age produce a recognizable list:
Soil does the most damage. Houston’s gumbo clay holds an enormous amount of water, expanding significantly when saturated and contracting hard during dry stretches. Buried pipe rides that movement season after season. Joints separate, older pipe cracks, and sections of line settle out of grade.
Subsidence adds another layer. Parts of the Houston area have settled measurably over decades, and a sewer line installed at a correct half-inch-per-foot fall can lose that pitch entirely as the ground beneath it drops.
The rest of the picture:
Getting the cause right is the whole job. A line with roots at one joint and a line with twenty feet of corroded cast iron call for completely different work and very different budgets.
Every sewer repair we perform starts with a camera inspection. We identify the pipe material, locate the damage precisely, measure the depth, and map the route before quoting anything.
From there we present the options honestly. A single failure point may only need a spot repair. Damage across multiple joints often makes trenchless lining the better choice, rebuilding the pipe from the inside without trenching through a yard, driveway, or slab. Molberg Plumbing is Picote Solutions certified, so we do this work ourselves.
You’ll see the camera footage and decide with the same information we have.
When a line is corroded end to end or has collapsed, replacement is what actually resolves it. We handle permits, utility locating, excavation, new pipe installed at proper fall, and testing before backfill.
Houston lots often have mature trees, fences, and limited access, so we plan the route to work around what’s there and keep the footprint tight. The ground gets restored and the work gets documented for your records.

It’s mostly the soil. Gumbo clay expands and contracts dramatically with moisture, which moves buried pipe constantly. Add ground subsidence, a high water table, and a lot of aging cast iron, and Houston sewer lines work harder than they do in most cities.
It’s a good idea. Saturated soil moves pipe, and floodwater can push silt and debris into a line through cracks or open joints. A camera inspection afterward tells you whether the system came through it intact.
Yes. We’ve been running service in the north Houston area for several years and are continuing to expand our presence there. Call and we’ll let you know our current coverage for your address.
It typically means tunneling or breaking through the slab to access the pipe, depending on the layout. Tunneling from outside avoids opening the floor inside the house but costs more. We’ll walk you through both approaches with the pricing attached.
Often, yes. Trenchless lining works well when the host pipe has enough integrity to bond a liner. Severe bellies or fully collapsed sections still require excavation, and the camera inspection tells us which situation you’re in.
Sewer leaks under a slab often come with odor, damp flooring, or sewage smells that a fresh water leak wouldn’t produce. We use camera inspection and leak detection to determine which system is involved before anyone breaks concrete.
Water heaters, repipes and sewer lines don’t wait for a good month. Get the price on paper first, then pay it off over time.
