Underground Sewer Repair Houston

When drains back up, yards smell like sewage, or foundations crack, you require underground sewer repair in Houston from a specialized team. Tunnel Now quickly repairs broken, collapsed, and root-infested sewer lines using trenchless technology and under slab tunneling, without tearing up your house or yard. You get a permanent fix, a clean property, and the assurance that the job was completed correctly.

Last spring, a Meyerland homeowner noticed a soft, soggy patch in her backyard that grew larger with each rainfall. She contacted two general plumbers before discovering Tunnel Now. Within an hour, our sewer camera detected a collapsed clay pipe buried six feet underground. Two days later, her yard looked as if nothing had happened: no massive trench, torn-up landscaping, or chaos.

That is proper underground sewer repair in Houston.

Houston’s expansive clay soils are constantly shifting. Tree roots burrow their way into old pipes. Heavy rains on Buffalo Bayou and Brays Bayou stress sewer lines that were installed 40 or 50 years ago. If you have a sewer backup, slow drains, foul sewage odors, gurgling toilets, wet spots in your yard, foundation cracks, or a high water bill, the problem is almost always underground and requires a specialist rather than a general faucet-fixing plumber.

Tunnel Now specializes solely in underground sewer work. We’ve repaired sewer lines under slabs, through tight yards, and beneath commercial buildings all over the Houston metro area, from The Woodlands to Pearland, Katy to Baytown.

Underground Sewer Repair

When a sewer pipe cracks, collapses, or becomes clogged with roots deep underground, most people are unsure where to begin.

Tunnel now does. We handle all stages of underground sewer repair in Houston, from the initial camera inspection to the final cleanup.

Whether your home is in the Heights, Montrose, or Sugar Land, our crews accurately diagnose the problem before beginning digging. We fix it correctly the first time.

Sewer Line Replacement

Sometimes a repair is insufficient. When a pipe is too far gone, cracked along its entire length, corroded cast iron, or collapsed due to shifting soil, full sewer line replacement is necessary. We replace old clay, cast iron, and Orangeburg pipes with modern PVC that will last decades.

Under Slab Tunneling

Many Houston homes are built on concrete slabs, which means broken sewer lines run directly underneath your foundation. Instead of jackhammering your floors, Tunnel Now hand-digs tunnels beneath your slab to access and repair the damaged pipe without ever touching your home’s interior. It’s cleaner, safer, and less disruptive for your family.

Sewer Camera Inspection

Before we do anything else, we send a high-resolution camera down your sewer line to see exactly what is going on underground. There’s no guessing. There will be no unnecessary digging. Our sewer camera inspection gives you a clear picture of root intrusion, bellied pipe sections, offset joints, or collapsed sections so you know precisely what you’re dealing with.

Hydrostatic Leak Detection

If you failed a hydrostatic plumbing test, which is common when buying or selling a home in Houston, Tunnel Now can identify the exact source of the leak. We isolate each section of your plumbing system and conduct water pressure tests to find even the smallest leak. This is one of our most popular services in River Oaks, West University Place, and Bellaire.

Trenchless Sewer Repair

Not every repair requires digging up your yard. Trenchless sewer repair methods let us fix broken or deteriorating pipes from the inside, with minimal disturbance to your lawn, driveway, or landscaping. It’s faster, often more affordable, and much less mess for the homeowner.

Sewer Line Cleaning

Grease buildup, debris, and root intrusion can slow your entire sewer system to a crawl. Regular sewer line cleaning keeps your pipes flowing freely and prevents the kind of full blockage that turns into a sewage backup inside your home. We clean residential and commercial lines across the Houston metro.

Pipe Bursting and Relining

Pipe bursting pulls a new pipe through the old damaged one, breaking it apart as the new line goes in. Pipe relining coats the inside of an existing pipe with a structural liner that bonds to the pipe walls and seals cracks from the inside. Both methods are minimally invasive and work well in tight yards or under driveways where traditional excavation isn’t practical.

Emergency Sewer Repair

Sewage backing up into your home at 10 PM isn’t something that can wait until Monday. Tunnel Now offers emergency sewer repair across Houston because sewer failures don’t follow business hours. If you’re in Pasadena, Humble, or downtown Houston and you have a sewer emergency, call us now.

Cured-in-Place Pipe (CIPP) Lining

CIPP lining is one of the most effective ways to restore an old, leaking sewer line without excavation. A resin-saturated liner is inserted into the damaged pipe and cured in place, creating a brand-new pipe inside the old one. It’s durable, long-lasting, and ideal for older neighborhoods in Houston where pipes have been in the ground for decades.

Drainage Service

Sewer Backup Service

A sewer backup can happen fast — one day your drains are slow, the next day raw sewage is on your floor. We respond quickly to sewer backup calls across Houston and get your system cleared and flowing again.

Main Line Clog Removal

The main sewer line is the single pipe carrying waste from your home to the city system. When it clogs, everything backs up. We clear main line clogs fast using professional-grade equipment that homeowner tools can’t touch.

Hydro Jetting

Hydro jetting blasts the inside of your sewer pipes with high-pressure water — up to 4,000 PSI — stripping away grease, scale, and root fibers that cable machines leave behind. It’s the most thorough way to clean a sewer line.

Foundation Drainage Repair

Poor drainage around your foundation leads to water intrusion, soil erosion, and eventually structural damage. We repair and install French drains, channel drains, and underground drainage systems to redirect water away from your home.

Storm Drain Cleaning

Clogged storm drains cause flooding, especially in low-lying Houston neighborhoods like Greenspoint, Atascocita, and areas near White Oak Bayou. We clean and restore storm drain systems for residential and commercial properties.

Exterior Drain Repair

Broken or settled exterior drains let water pool in the wrong places. We repair, reroute, and replace exterior drain lines to keep your property protected after heavy rain.

Excavating Contractor Services

Under Slab Excavation

When underground pipe access requires it, we excavate beneath concrete slabs carefully and precisely. Our crews protect your foundation while creating the access needed to complete the repair.

Trenching and Shoring

For deeper pipe repairs and new sewer line installations, safe and properly shored trenching is non-negotiable. Tunnel Now follows all OSHA trenching guidelines to protect both workers and your property.

Utility Line Excavation

We safely excavate around existing utility lines — gas, electric, water — to reach damaged sewer infrastructure without causing additional damage. Precision matters when working in tight urban areas like Midtown and Montrose.

Hand-Dug Tunneling

In locations where machine access is impossible, our crews hand-dig tunnels to reach pipes under slabs, driveways, and structures. This is a specialty of Tunnel Now and sets us apart from general plumbing companies in Houston.

Commercial Sewer Excavation

We handle large-scale sewer excavation projects for commercial properties, apartment complexes, and industrial facilities across Houston and Fort Bend County. Our crews work efficiently to minimize business disruption.

Sewer Line Trenching

New sewer line installations, replacements, and tie-ins all require properly executed trenching. We trench sewer lines to the correct grade and depth, following local Houston municipal code requirements.

Why Houston Homeowners Trust Tunnel Now

Houston’s soil is unlike anywhere else in the country. The heavy clay expands when it gets wet and contracts during dry spells, which means pipes are constantly being pushed, pulled, and stressed year after year. Add in the massive oak and magnolia trees common in neighborhoods like the Heights and River Oaks — whose roots actively seek out sewer pipe joints — and you’ve got a recipe for sewer problems that repeat themselves if they’re not fixed properly the first time.

We’ve worked in every type of Houston home — 1950s pier-and-beam houses in Montrose, post-war slab homes in Pasadena, new construction in Cinco Ranch and Woodlands neighborhoods. We know the difference between a pipe that just needs cleaning and one that needs to come out entirely. That knowledge saves our customers time and money.

Common signs you need underground sewer repair in Houston:

  • Sewage odors in your yard or near your foundation
  • Multiple slow drains throughout the house at the same time
  • Gurgling sounds from your toilet when you run the sink
  • Unexplained wet areas or sinkholes near your foundation
  • Recurring clogs that keep coming back no matter how many times you snake the drain
  • Backed-up floor drains in your garage or utility room
  • High water bills without an obvious cause
  • Foundation cracks that appeared without a clear reason

If any of these sound familiar, the problem is almost certainly underground. Call Tunnel Now before it gets worse.
