When water backs up out of a sink, tub, or floor drain instead of going down, or sewage comes up through a toilet, tub, or floor drain, something downstream is blocked and continuing to run water makes it worse. Spencer's Plumbing provides 24/7 drain cleaning across Greater Houston, starting with an assessment to identify whether you have a localized clog, a blocked main drain line, or a full sewer-line backup before we touch it.
Stop using all water sources immediately, and if sewage is present or water is backing up, keep people and pets away from the area and call a professional plumber. A licensed plumber is typically on site within 30 to 60 minutes, and emergency drain cleaning can often begin within an hour.
Not every backup is the same emergency, and we diagnose whether you have a clogged drain, a drain backup, or a sewer backup before clearing anything, because treating a main-line or sewer backup like a simple clog just delays the real fix.
We identify the real cause of persistent drainage issues before choosing the right fix.
The common causes in our area are specific:
● Tree root intrusion into sewer and drain lines, especially in mature-tree neighborhoods like Kingwood and Atascocita where decades-old trees sit over older clay and cast-iron lines
● Grease, wipes, and buildup accumulating in older lines
● Bellied or cracked pipe from clay-soil shifting beneath the home
● Scale buildup from hard water narrowing older galvanized drains
● Municipal main backups during heavy rain and flooding (sewer backups specifically)

Our emergency process diagnoses the real cause before clearing the blockage:
If a drain or sewer line backs up more than once, the cause is rarely simple buildup, it's usually roots, a belly, or a crack in the line. We camera the line to show you the actual cause so you fix it permanently instead of paying to clear the same clog repeatedly.
Several fixtures backing up together, or sewage itself appearing, points to the main line rather than a single fixture. This needs a main-line diagnosis, not a fixture-by-fixture approach, and we treat it accordingly.

Multiple fixtures backing up at the same time almost always means the blockage is in your main line, not a single fixture drain. Stop running water and call us, this needs a main-line diagnosis.
Yes, raw sewage is a health hazard. Stop using all water in the home, keep people and pets away from the affected area, and call 832-658-2569. We respond 24/7.
We do not recommend it for an active backup. Chemical cleaners often do not reach a deep clog, can damage older pipe, and create a hazard for the plumber who works on the line afterward. Call us instead.
Repeated backups usually point to a structural cause, tree roots, a bellied pipe, or a crack, not simple buildup. A sewer camera inspection shows the actual cause so you can fix it permanently rather than clearing the same clog again.
When we suspect a recurring, main-line, or sewer cause such as root intrusion or a bellied pipe, we run a sewer camera inspection so you can see the actual cause rather than guessing.
A licensed plumber is typically on site within 30 to 60 minutes across Greater Houston, day or night.
