Basement Water Removal in Houston, TX

What is basement water removal?

Basement water removal is the pumping-out of water that has collected in a basement or another below-grade space. Because these areas sit below ground level, water that gets in has nowhere to drain and pools at the lowest point.

That trapped water will not leave on its own. It has to be pumped out, and then the walls and floor need to be checked for moisture that has soaked in. Removing it promptly protects the space and the structure around it.

Why does water collect in basements and below-grade spaces?

Water collects in below-grade spaces because they are the lowest point, and water always flows downhill. Once it reaches a space below ground level, it stays there until it is removed.

Common reasons water gets in include:

Heavy rain overwhelming drains and gutters
Poor drainage around the foundation directing water inward
Groundwater seeping through walls or floors
Plumbing or appliance failures on a lower level

In the Houston area, full basements are uncommon because most homes are built on slabs, but below-grade rooms, crawl spaces, and low-lying areas take on water for these same reasons.

How is water removed from a basement?

Water is removed from a basement from the bottom up, starting with the deepest water and working toward a dry floor.

Safety check. We confirm it is safe to enter and check for electrical hazards before starting.
Pump out the bulk. Submersible pumps move large volumes of water out of the space.
Extract the rest. Extractors pull the remaining water off the floor.
Check for soaked-in moisture. We measure moisture in the walls and floor, since below-grade materials hold water.

Why below-grade water needs prompt removal

Below-grade water needs prompt removal because it sits against the structure and cannot evaporate or drain away like water in an open room. The longer it stays, the more it soaks into walls, floors, and anything stored down there.

Standing water below grade also raises the humidity of the whole space, which encourages mold on damp surfaces and stored items. Pumping it out quickly limits that damage and starts the space drying.

Is standing water in a basement dangerous?

Standing water in a basement can be dangerous, so caution comes first. Water can reach submerged outlets, wiring, and equipment, creating a serious electrical hazard, and below-grade water may be contaminated by groundwater or backups.

Do not enter a flooded basement while the power to that area is on, and stay out if the water is deep or its source is unknown. When there is any doubt, let a professional remove the water safely rather than wading in.

Frequently asked questions

How do you remove water from a basement?

We use submersible pumps to move the bulk of the water out, then extractors to pull the remaining water off the floor. After that we check the walls and floor for moisture that has soaked in below grade.

Are basements common in Houston?

No. Most Houston homes are built on concrete slabs rather than over basements, because of the region's high water table and soil. Full basements are uncommon here, but below-grade rooms, crawl spaces, and low-lying areas still take on water and need the same removal.

Why does my below-grade space keep taking on water?

Below-grade spaces sit at or below the surrounding ground level, so water drains toward them and can seep in through walls and floors. Heavy rain, poor drainage, and groundwater are common reasons water keeps collecting there.

Is it safe to go into a flooded basement?

Not until it is checked. A flooded basement can hide submerged outlets and electrical hazards, and the water may be contaminated. Do not enter it while the power to that area is on, and let a professional handle removal when the water is deep or its source is unknown.
