Multiple fixtures slow or backing up at the same time. Here's what to do about main drain clogs in Houston — including the local factors that change the advice.
Do this right now
Confirm the pattern
Run water in an upstairs sink and watch the lowest drain. If the low drain reacts, the blockage is in the main line between them.
Stop adding water
Limit water use — every gallon has to go somewhere, and right now 'somewhere' is your lowest drain.
Find your cleanout
The main-line cleanout (usually a capped pipe near the house or in the yard) is where a pro will work. Knowing its location speeds everything up.
Don't chemical it
Chemical cleaners can't clear main-line clogs and make the line hazardous for the pro with the auger.
Call for pro clearing
Call (844) 699-1165. Main lines need a powered auger or hydro-jetting — and a camera inspection to find why it clogged.

What makes main drain clogs different in Houston
- slab-on-grade homes across flat bayou country, many built from the 1960s–90s — the pipe materials used in this era determine your root and scale risk.
- Gumbo clay soil shifts dramatically between wet and dry seasons — soil movement here can belly or separate older lines.
- In Houston, hurricanes, tropical storms, and intense Gulf humidity
- Flat terrain and high water table mean flooding, not basements — storm drainage overwhelms systems fast
