Garland’s housing boom, and the pipes it left behind
Garland had 10,571 residents in 1950, 38,501 in 1960, 81,437 in 1970 and 138,857 in 1980 (U.S. Census). A large share of the city's single-family homes date from those thirty years. Here's what that means by neighborhood:
- Travis College Hill and the older blocks around downtown (homes from 1913 to about 1960). The Travis College Hill Historic District was Garland's first National Register listing. The oldest lines here can be clay, cast iron or even Orangeburg.
- Eastern Hills (median home built 1967). Classic 1960s ranch homes. Expect cast iron under the slab and clay in the yard.
- Club Hill (median 1976) and Camelot (median 1977). 1970s construction, often cast iron under the house transitioning to plastic outside, with root and belly problems along the way.
- Embree and the original east-side town. Garland formed in 1891 when Embree and Duck Creek merged; homes here span many eras, so the camera decides.
Where’s your cleanout? Garland’s own rule of thumb
The City of Garland says homes built before 1970 usually have their sewer cleanout in the back yard, in line with the main toilet vent, and homes built after 1970 usually have it in the front flower bed. Many older Garland lots drain toward an alley, so the line may run out the back (common pattern; confirm on site).
Garland’s tip is useful before you call anyone: if the cleanout is dry and the house is backing up, the stoppage is under the house. If the cleanout is holding water or overflowing, the stoppage is toward the City’s main.
Garland sewer replacement requirements, and how we meet them
The City of Garland spells out what a sewer replacement must include. We build every Garland job to these rules:
A permit for replacement of any portion of a sewer line.
At least 1/8 inch of fall per foot, with the pipe bedded along its full length.
A two-way cleanout close to the house.
The new line extended at least 1 foot past the property line.
A water test filled to the top of the cleanout, with every joint exposed and no water in the ditch.
After inspection, a temporary tie-in so you have sewer service; the Garland Water Department then makes the permanent connection, which takes about three working days to start.
That last step matters for your schedule: we plan the job so you’re never without a working toilet while the City finishes the tap.
How the job runs
- Camera inspection and locate (you keep the video). See sewer camera inspection.
- Itemized quote: tunnel feet, trench feet, access holes.
- Permit pulled; utilities marked.
- Tunnel under the slab from outside so floors stay intact; trench the yard or alley run.
- New PVC and two-way cleanout, water test, City inspection, temporary tie-in, then backfill.
Where the old pipe is still round and the route is open, trenchless pipe bursting can replace a yard section without a full-length trench.
What sewer line replacement costs in Garland
Example 1 (illustration only): a 1960s Eastern Hills ranch with 25 feet under the house, 1 access hole and a 55-foot run out the back to the alley: 25 × $425 + $1,150 + 55 × $180 = $21,675, or $18,423.75 approved same day.
Example 2: yard line only, no work under the house, 60 feet of trench: 60 × $180 = $10,800, or $9,180 same day.

Garland sewer line replacement FAQs
How much does sewer line replacement cost per foot?
Our published prices are $425 per foot for tunneling under the slab, $180 per foot for open trenching in the yard, and $1,150 per access hole. Most jobs mix the three. Your final price is confirmed in writing after an on-site inspection, usually with a camera, before any work starts.
Do I need a permit to replace a sewer line in Garland?
Yes. The City of Garland requires a permit for replacement of any portion of a sewer line, plus a water test and inspection. We handle the permit, the inspection and coordination with the Water Department.
Where is my sewer cleanout in Garland?
Per the City, homes built before 1970 usually have it in the back yard in line with the main toilet vent; homes built after 1970 usually have it in the front flower bed. Most have a double cleanout.
How do I know if the clog is mine or the City's?
Open the cleanout. Dry cleanout with a backup inside means the stoppage is under the house. A cleanout holding water or overflowing means the stoppage is toward the City's main. Call the City for a main-line problem.
Why does Garland make me wait for the Water Department?
After the inspection, the City makes the permanent sewer connection itself, and it takes about three working days to start. You'll have a working temporary tie-in in the meantime.
Do you dig up my floors?
Usually not. We tunnel under the slab from outside. If a short indoor access hole is cheaper for your layout, we'll quote both.
