You cleared the drain last month, congratulated yourself on a job well done, and went back to normal life. Then Saturday morning arrives: the toilet gurgles ominously when the shower runs, wastewater starts creeping up through the bathtub drain, and your hallway smells suspiciously like a municipal water treatment facility. Running another snake down the pipe to temporarily punch a hole through the blockage is just putting a Band-Aid on a broken leg—it doesn’t answer the real question of whether your sewer line has collapsed, cracked, or been invaded by tree roots.
In Richardson—where four in ten properties carry 50-year-old architectural bones under their roofs—underground sewer pipes have survived five decades of clay soil expansion, aggressive tree root invasion, and piecemeal bathroom remodels. Before you let anyone bring a backhoe into your front yard, Harlen Johnson HVAC, Plumbing & Electrical uses high-definition camera diagnostics to pinpoint the exact structural failure and determine whether the break sits on your private property lateral or the City’s side of the cleanout.
Service | When You May Need It | What We Evaluate |
Sewer Camera Inspection | Backups return every few weeks after the line was cleared. | Cracked pipe, offset joints, root entry points, and bellied or collapsed sections. |
City Cleanout Boundary Check | A backup that may sit on the City’s side of the two-way cleanout. | Cleanout location, private lateral versus City-maintained line, and main connection. |
Spot Sewer Repair | One broken joint or cracked section in an otherwise healthy line. | Failure depth and location, pipe material, and the 4-to-10-foot section to replace. |
Root Intrusion Repair | Roots keep clogging the line after jetting or snaking. | Root entry seams, loose fittings, joint condition, and the damaged pipe section. |
Under-Slab Sewer Repair | Camera footage shows the failure beneath the concrete foundation. | Pipe depth, failure location, direct slab access, and rerouting options. |

Your toilet doesn’t print out a map when it backs up—it just overflows onto your bathroom tile. However, Richardson has a specific property-line policy that can save you thousands of dollars if you check boundaries before excavating:
Richardson operates a 24/7 Response Center at 972-744-4111. If you suspect the blockage sits on the City’s side of the cleanout, they can inspect the municipal section first before you pay for private excavation.
In a city where four out of ten homes carry five decades of history, underground plumbing has survived countless home improvement projects.
Picture a typical 1974 ranch home: the kitchen was remodeled in 2002, a hall bathroom was updated in 2015, and a previous owner patched a six-foot section of sewer line somewhere in the yard back in 2018 without leaving paperwork. When your main line backs up every three months, simply blaming “an old house” doesn’t help—you need to know exactly which section of pipe is failing today.
Drain cleaning and sewer line repair solve two completely different problems:
If your pipe is cracked or collapsed, running a drain snake down the line clears the immediate traffic jam, but it doesn’t rebuild the highway. The blockage will return as soon as waste catches on the broken edge again.
Your lawn cannot tell you which joint separated three feet underground. Guessing where to dig usually results in torn-up landscaping and wasted labor costs.
Our high-definition fiber-optic sewer cameras travel down your line, transmitting real-time video to locate exact pipe conditions:
Paired with above-ground radio transmitters, we pinpoint the exact depth and location of the failure so excavation is limited strictly to the damaged section.
A broken sewer line does not automatically mean you have to dig up your entire front yard from the foundation to the curb:
Richardson’s beautiful, mature oak and pecan trees are great for summer shade, but their root systems are relentlessly searching for water. Roots do not drill through solid, undamaged pipe—they enter through microscopic cracks, loose fittings, or failing joints.
Once inside, roots feed on moisture and catch passing waste, forming a dense clog. While hydro jetting or mechanical snakes slice away the root mass inside the pipe, they don’t seal the entry point. To stop roots permanently, we must repair or replace the damaged pipe section to lock them out for good.
When diagnostics reveal that a sewer line failure sits directly beneath your concrete foundation, the repair strategy changes. Instead of open yard digging, under-slab repairs require precise location before making any cuts.
Depending on pipe depth, location, and structural layout, we evaluate direct slab access or pipe rerouting to restore drainage with minimal disruption to your interior flooring.

Richardson maintains the municipal main line. If your home has a City-installed two-way cleanout, the City maintains the pipe from that cleanout to the street main, while the homeowner is responsible for the private line running from the cleanout back to the house.
You can contact the City of Richardson 24-Hour Response Center at 972-744-4111 to request a municipal sewer line check.
Not necessarily. Recurring backups can be caused by heavy tree root intrusion, offset joints, or belly dips holding grease. A video camera inspection is required to determine if the pipe is cracked, misaligned, or collapsed.
Yes. If camera diagnostics show that 90% of your sewer lateral is in good condition and only one 5-foot section has a crack or joint failure, a spot repair can be completed without replacing the entire line.
No. Hydro jetting uses high-pressure water to scrub grease, scale, and root masses out of an intact pipe. It cannot repair physical cracks, crushed sections, or separated pipe joints.
