San Antonio storms don't knock. One minute the sky's clear, the next you've got water sheeting off the driveway and pooling around the house. When the ground can't drink it fast enough, that water finds the lowest spot: your crawl space, your garage, the room built on a low slab. A sump pump is what stands between that water and your floors. When it quits, you find out fast.

A plumber starts by finding out why the pump isn't keeping up. Sometimes it's a stuck float switch, a clogged intake, or a check valve that's letting water run right back into the pit. Sometimes the pump itself burned out or the pit's just too small for how much water your yard sends its way. We test the float, the switch, and the discharge line, then run water through it to watch it cycle. If it needs a new pump or a battery backup for when the power drops, we tell you what we found and what it takes to fix it.

Around here the clay soil is the real troublemaker. It swells when it's wet and sheds water instead of soaking it in, so runoff builds up fast during those heavy Hill Country downpours. Homes in older pockets like Monte Vista and Olmos Park weren't always built with drainage in mind, and newer builds out in Stone Oak, Boerne, and New Braunfels sit on ground that moves. We've pulled water out of houses in Southtown after a spring storm and set up backup systems in Schertz and Cibolo before the next front rolled through. Point is, we know how the water moves in this town.

If your pump's already down and water's coming in, don't wait it out. A plumber can be at your door in about 45 minutes to clear the pit, get you draining, and keep the damage from spreading.

Common questions

Do I even need a sump pump in San Antonio if I don't have a basement?
Plenty of homes here do. Crawl spaces, low garages, and rooms on low slabs all collect water during heavy rain, and our clay soil sheds runoff toward the house instead of soaking it up. If you've had water come in during a storm, a pump and good drainage make a real difference.
My pump runs but water keeps coming back in. What's wrong?
Usually the check valve. It's supposed to stop water in the discharge line from draining back into the pit. When it fails, the pump keeps pumping the same water in a loop. It could also be a pit that's too small or a clogged discharge line. A plumber can tell which by watching it cycle.
Can you set up a backup for when the power goes out?
Yes. Storms that flood also knock out power, which is exactly when your pump needs to run. We install battery backup systems that kick in automatically so the pit keeps draining even with the electricity down.
How fast can someone get here if water's coming in?
A plumber can reach most of San Antonio and the surrounding towns in about 45 minutes. Shut off any power near the water if you safely can, then call and we'll head your way to clear the pit and stop the spread.
