Most Houston-area homes are built on concrete slabs, with all drain and sewer lines running underneath the foundation. That means when something goes wrong below grade, you need a team that understands how these systems are built and how to access them without tearing up your property. Spring Branch AC's plumbing division handles everything from a simple drain clog to a full sewer line replacement. Every technician on staff is cross-trained in both HVAC and plumbing, holds NATE certification, and works under Texas license #TACLB49330E. Here is what we cover.
Slow-draining sinks, tubs, and showers are usually caused by buildup inside the drain line. Spring Branch AC clears blockages professionally and gets water flowing again. We advise against using chemical drain cleaners before calling a plumber. Most chemical drain products are highly toxic and can deteriorate pipes from the inside out over time, potentially turning a simple clog into a full drain line replacement. For routine maintenance between service calls, drain products containing "friendly" bacteria and enzymes are a safer option for keeping grease and sludge from building up.
When a drain line is cracked, corroded, or has separated at a joint, cleaning alone will not solve the problem. Spring Branch AC repairs damaged drain lines throughout the home, including the primary AC condensation drain that routes to a bathroom sink in most Houston-area houses. Algae and organic buildup at that connection point is the most common cause of AC drain line backups. We clear these clogs by disconnecting the primary drain at a shutoff valve and pushing compressed nitrogen back through the line to blow out the blockage. The algae and debris are then cleaned from the bathroom sink connection.
Most residential plumbing leaks are found in the toilet tank, typically caused by worn parts or improper alignment of flushing mechanisms. Even small, silent leaks can significantly increase monthly water bills. Spring Branch AC locates and repairs leaks throughout the plumbing system, from toilets and supply lines to less obvious sources behind walls and under fixtures.
Over time, sewer lines accumulate buildup from grease, waste, and organic material. If left unaddressed, that buildup restricts flow and eventually causes backups into the home. Spring Branch AC provides professional sewer cleaning to restore full flow through the main sewer line.
When the cause of a sewer problem is not obvious from the surface, a video camera inspection lets us see exactly what is happening inside the pipe. Spring Branch AC feeds a camera through the sewer line to identify blockages, cracks, root intrusion, pipe separation, and deterioration, all without any excavation. Video inspection is also useful before purchasing a home. Knowing the condition of the sewer line under the slab can prevent expensive surprises after closing.
This is where Spring Branch AC's experience matters most. In Texas, most homes sit on concrete slabs with all drain and sewer lines embedded underneath. When the ground shifts (which is common in Houston's expansive clay soils), pipes crack, separate, or collapse. Accessing a damaged sewer line under a slab requires tunneling beneath the foundation. Spring Branch AC uses experienced crews who manually excavate tunnels beneath the slab to locate and repair the damaged pipe. This approach avoids large-scale excavation of the slab itself, keeping disruption to the home and property to a minimum. For a detailed walkthrough of how sewer line repair works under a Houston-area home, see our guide to sewer line repair in Houston, TX.
When a sewer line has deteriorated beyond the point where a targeted repair makes sense, full replacement is the next step. Spring Branch AC replaces sewer lines using the same manual tunneling approach, working beneath the slab to remove the failed pipe and install a new one. The decision between repair and replacement depends on the extent of the damage, the age of the pipe, and whether problems are isolated to one section or spread across the line. A video inspection beforehand gives us the information we need to recommend the right approach.
Drain and sewer problems usually show up in small ways before they become emergencies. Here is what to watch for.
A single slow drain is usually a localized clog. Multiple slow drains at the same time often point to a blockage deeper in the sewer line.
Gurgling typically means air is trapped in the plumbing system. This is often caused by a partial blockage in the main sewer line or a problem with the plumbing vent on the roof.
A persistent sewage smell may indicate a cracked sewer line under the slab, a dry P-trap, or a damaged plumbing vent that is no longer directing sewer gases outside the home.
When flushing one toilet causes water to rise in another fixture (a tub, a floor drain, or another toilet), the main sewer line is likely blocked or damaged.
Patches of saturated ground with no obvious water source can indicate a sewer line break between the house and the street.

When plumbing and HVAC problems overlap (water heater venting, AC drain lines), our technicians diagnose the full picture instead of sending you to a second contractor.
Yes. Spring Branch AC's crews manually tunnel beneath the slab to reach the damaged pipe. This avoids breaking through the foundation and keeps disruption to the home and property to a minimum. The approach requires experienced crews who know how to excavate safely under a residential slab.
A single slow drain that responds to a plunger is usually a simple clog you can handle yourself. Call a plumber when multiple drains are slow at the same time, when a drain keeps coming back after clearing, when you notice sewage odors, or when water is backing up into other fixtures. These are signs of a deeper issue that needs professional diagnosis.
