Heavy rain.
Tulsa averages roughly 40 inches of rain a year, and spring storms can drop several inches in a few hours. Water can overwhelm yard drainage and press against foundations.
Flooded Basement Cleanup in Tulsa, OK Sump Pump Failure & Crawl Space Flooding, 24/7
Submersible Pumping & Hydrostatic Clay Seepage Relief.
A flooded basement or crawl space is more than a mess. Groundwater and storm runoff soak concrete, framing and everything stored below, and mold can start within 24 to 48 hours. Our Tulsa crews pump water out safely, remove what cannot be saved, dry the structure and check every inch with moisture readings. We answer 24 hours a day and aim to arrive within 60 minutes.
Act Fast, Stay Safe
Basement Flooded? Do This First
- 01
Stay out if the water is deep or touching outlets, the panel, a furnace or a water heater.
Water and electricity can be lethal. If water has reached the panel or meter, call PSO. Never wade through water to a breaker.
- 02
Do not run gas-powered pumps, generators or pressure washers indoors.
They produce carbon monoxide.
- 03
Stop the source if it is inside
(supply line, water heater, washing machine). Outside water you cannot stop.
- 04
If you smell gas,
leave and call Oklahoma Natural Gas or 911.
- 05
Treat the water as contaminated.
Wear waterproof boots, gloves and a mask if you must enter a drying area, and keep children and pets out.
- 06
Photograph and video
the water line, damaged items and appliances before moving anything.
- 07
Lift valuables
from low shelves and floors. Do not move heavy items alone.

Important Warning
Why You Should Not Pump the Basement Dry All at Once
When the soil around your house is saturated, the water outside pushes against your foundation walls and slab as much as the water inside pushes back. If the basement is emptied too quickly, that outside pressure can crack or shift walls or lift a slab.
The commonly recommended approach is to pump gradually, typically a portion of the depth at a time, then pause and check before continuing. That is why flooded basement cleanup after a big storm can take more than one day of pumping, not a few hours. Crews watch the water level outside and inside, and adjust.
This is one of the reasons to call a professional instead of renting a pump and emptying it yourself.
Know the Source
Where Basement Water Comes From
Knowing the source decides how contaminated it is and how it is handled.
| Source | Water category | Notes |
|---|---|---|
| Burst supply line or water heater inside the home | Category 1 (clean), can worsen if left | Easiest to handle if caught early |
| Washing machine or dishwasher discharge | Category 2 (gray) | Some contamination |
| Sump pump failure, groundwater seepage | Category 2 to 3 | Soil, bacteria and silt come with it |
| Surface runoff and flood water entering from outside | Category 3 (black) | Treated as contaminated |
| Sewer or drain backup | Category 3 (black) | See Sewage Backup Cleanup |
If you are not sure, assume it is contaminated until a technician tests and confirms.
Local Knowledge
Why Tulsa Homes Flood Below Grade
Many Tulsa homes do not have full basements. Slab-on-grade houses are common here. When people say "basement" in Tulsa, they often mean a partial basement in an older home, a lower level, a finished garage, a crawl space or an underground storm shelter. All of these can flood and all are cleaned up differently.
Creeks and floodplains.
Areas near the Arkansas River, Riverside Drive, Mingo Creek, Joe Creek and Bird Creek can see sudden runoff and rising groundwater. The May 1984 flood and the 2019 Arkansas River flooding are reminders of how quickly it happens.
Clay soil.
Much of the Tulsa area sits on clay that swells when wet and shrinks when dry. Wet clay presses against walls and drains slowly, and dry-season shrinkage can open gaps along foundations that rain later flows into.
Power outages during storms.
Severe thunderstorms and tornadoes can knock out power, and a sump pump with no battery backup stops exactly when it is needed.
Older homes.
Midtown, Maple Ridge, Florence Park, Brookside and Cherry Street have homes with older foundations, window wells and drainage that may not match today's rainfall.
Underground storm shelters and cellars.
Common across Oklahoma, they can fill with water from rain and seepage and need cleaning before they are safe to use in a storm.
Know What You Are Dealing With
How Much Water Is in Your Basement?
Use this to estimate. Gallons = square feet x depth in feet x 7.48.
| Floor area | 6 inches | 12 inches | 24 inches |
|---|---|---|---|
| 800 sq ft | about 2,990 gal | about 5,980 gal | about 11,970 gal |
| 1,000 sq ft | about 3,740 gal | about 7,480 gal | about 14,960 gal |
| 1,500 sq ft | about 5,610 gal | about 11,220 gal | about 22,440 gal |
One foot of water over 1,000 square feet weighs more than 62,000 pounds. That is also the pressure pushing on your walls and slab, and why gradual pumping matters.
Material by Material
What Floodwater Does to Each Material
| Material | What happens | What usually happens next |
|---|---|---|
| Concrete slab and block walls | Absorbs water slowly and releases it slowly, may show white mineral deposits (efflorescence) | Cleaned, dried and checked before flooring goes back |
| Carpet and pad | Soaks up water and contaminants | Usually removed after Category 2 or 3 water |
| Drywall and insulation | Wicks water upward and holds contaminants | Wet sections cut out, often 2 feet or more above the water line |
| Wood framing and sill plates | Absorbs moisture, can mold if left wet | Cleaned and dried in place |
| Cabinets and built-ins | Swell and delaminate | Case by case, particleboard rarely survives |
| Stored items, boxes, paper | Contaminated and moldy quickly | Usually discarded |
| Furnace, water heater, electrical panel | Can be damaged and unsafe | Inspected by a licensed professional before use |
Older home warning: homes built before about 1980 may contain asbestos in flooring, plaster, pipe wrap or ceiling texture, and homes before 1978 may have lead paint. Test suspect materials before tearing out or sanding anything.
How We Work
Our Flooded Basement Cleanup Process
- 01
Safety and utilities.
We check electrical and gas hazards before anyone enters and make sure gas-powered equipment stays outdoors.
- 02
Source and category assessment.
We determine where the water came from and how contaminated it is.
- 03
Controlled pump-out.
Submersible pumps remove water gradually, based on conditions outside. Discharge follows local rules. See Emergency Water Extraction for details of the equipment.
- 04
Remaining water and silt removal.
Extractors and wet vacuums clear the slab, low spots and floor drains. Silt and mud are shoveled and washed out.
- 05
Remove contaminated materials.
Carpet, pad, soaked drywall, insulation and ruined contents are bagged and removed.
- 06
Clean and sanitize.
Surfaces are scrubbed and treated with EPA-registered antimicrobial products.
- 07
Dry the space.
Dehumidifiers and air movers dry the slab, walls and framing. See Water Mitigation.
- 08
Moisture checks and documentation.
Readings, photos and drying records for your claim.
- 09
Prevention advice.
Notes on drainage, gutters and sump upgrades so it does not happen again.
Clean It Right
Cleaning and Sanitizing After a Basement Flood
Floodwater leaves bacteria and silt behind, even when it looks clear again.
- Surfaces that touched floodwater should be cleaned first, then sanitized. Disinfectant does not work on top of mud.
- Never mix bleach with ammonia or other cleaners. The fumes are dangerous.
- Wear protection: waterproof boots, gloves, eye protection and an N95 or better mask.
- Wash hands and clothing after cleanup, and keep children, pets and anyone immunocompromised out of the area.
- Throw away food, medicine and cosmetics that touched the water.
- Do not turn on a furnace, water heater or other appliance that was wet until a professional inspects it.
The Usual Suspect
Sump Pump Failure Why It Happens
- Power loss during storms, with no battery backup
- Pump too small for the amount of water coming in
- Stuck float switch that never turns the pump on
- Clogged intake or discharge line, or a frozen discharge pipe in winter
- Old pump that has reached the end of its life (often around 7 to 10 years)
- No check valve, so water flows back into the pit
If your home has a sump pit, test it each spring by pouring water in and confirming the pump turns on and drains.
Insurance Claims
Flooded Basement and Your Insurance Claim
Basement flooding coverage depends on where the water came from. Sudden pipe failures are commonly covered; outside flood water usually needs separate flood insurance.
We provide photos, moisture readings and drying records, and work with your adjuster. Coverage is decided by your insurer. Questions about your coverage? Call (918) 347-0890.
Stay Ahead
How to Prevent Basement and Crawl Space Flooding in Tulsa
- Gutters and downspouts: clean them and extend downspouts at least 6 feet from the house.
- Grading: soil should slope away from the foundation.
- Window wells: keep them clear and covered, with drains that work.
- Sump pump: test each spring, add a battery backup, and consider a high-water alarm.
- Sewer backwater valve: a plumber can install one to block sewer backups.
- Seal cracks and cold joints in the foundation (repairs for leaks should be done by a foundation or waterproofing professional).
- Store items off the floor in plastic bins.
- Keep a dehumidifier running in damp spaces in summer.
- Know your shut-off valve and the location of your electrical panel.
We clean up and dry flooded spaces. Permanent waterproofing or foundation repair is done by foundation or waterproofing specialists, and we will tell you if you need one.
Honest Pricing
What Affects the Cost of Flooded Basement Cleanup
- Depth and volume of water, and how long it sat
- Source and contamination category
- Size of the area and number of levels
- Finished vs unfinished space (carpet, drywall and cabinets cost more to replace)
- Amount of silt and debris
- Pumping time, including gradual pumping after storms
- Amount of drying equipment and days it runs
- Whether materials must be removed or disposed of as contaminated
Starting within the first day or two lowers the amount of material that has to be thrown away.

Flooded Basement FAQ
Flooded Basement FAQ
The most common causes are power loss, a stuck float switch, a clogged discharge line, a pump that is too small for the storm, or an old pump. A battery backup is the single best protection against storm outages.
Not necessarily all at once. If the ground outside is saturated, emptying the basement too quickly can damage walls and floors. Pumping is usually done gradually and monitored. Call a professional before starting if the water is deep.
Assume yes. Groundwater, runoff and sump overflow carry bacteria, silt and chemicals, and outside flood water is treated as contaminated. Wear boots, gloves and a mask, and keep children and pets away.
Usually not. Basements are cool and damp, and in Tulsa's humid weather open windows can bring in more moisture. Concrete holds water for a long time. Dehumidifiers and monitored drying are the reliable method.
Remove wet carpet, pad and soaked drywall quickly, clean and sanitize surfaces, and dry the space with dehumidifiers. Mold can begin to grow in 24 to 48 hours on wet materials. See Mold Remediation.
Usually 3 to 7 days, depending on the depth and time the water sat, the materials involved and the humidity. Concrete and block walls are slow to dry, so we confirm dryness by readings.
Not until they are inspected. Wet gas valves, controls and electrical parts can be unsafe even if they seem to work.
It depends on the source. Burst pipes and sudden appliance failures are commonly covered. Sump pump failure and sewer backup usually need an endorsement. Flood from outside needs flood insurance. Check your policy and call your insurer.
Water that shows up through floor cracks, wall joints or window wells during rain is usually groundwater or surface runoff. Dirty or foul-smelling water coming from floor drains, toilets or sinks points to a sewer backup. If you are unsure, treat it as contaminated.
Yes. Crawl spaces trap moisture under the house and can wet insulation and the subfloor. They need careful pumping, removal of wet insulation and drying. Call us and we will explain what to expect.
Keep out until it is pumped and cleaned. Standing water can hide hazards and shelters are airtight, so mold and bacteria build up fast. We can pump, clean and dry it so it is ready for storm season.
We clean up and dry flooded spaces and tell you what is causing the problem. Permanent waterproofing and foundation repair are done by specialists.
Yes. We answer 24 hours a day, 7 days a week.
