AfterFlood Cleanup in Houston, TX
Flood cleanup in Houston means removing standing water, drying out every surface it touched, and making sure mold never gets a foothold. In a city where a summer thunderstorm can drop four inches of rain in an hour and bayous rise faster than drivers can reroute, floodwater enters homes through doors, foundation cracks, backed-up drains, and saturated ground. Tidemark Water Damage Houston handles the full cleanup with written pricing before any work starts, pet-safe products, and the 365-Day Done Right Promise behind every job we finish. If water is inside your home right now, call (325) 423-6800 and a live person answers, day or night.
Flood cleanup is a specific service under our broader Water Damage Restoration work. The difference matters: a burst pipe is a contained incident, but floodwater brings in whatever was on the ground outside, which is why our technicians treat every flood job as a contamination risk first and a drying job second. We follow the tide mark, the line water leaves on a wall, to find exactly how far water traveled and dry past it. You can learn more about how we approach the full scope of restoration on our Water Damage Restoration in Houston page.
When You Need Flood Cleanup
Not every wet floor requires a full flood cleanup crew. But these situations do, and they are more common in Houston than almost anywhere else in the country:
- Standing water from street flooding or bayou overflow. Water that came from outside carries silt, bacteria, and whatever else was on the street. It needs extraction and sanitizing, not just towels and a fan.
- Water rising through floorboards after heavy rain. Houston’s clay-heavy soil expands when saturated, pushing groundwater up through slab foundations. You’ll see dark patches spreading across tile or wood floors, often in the room closest to the lowest point of the yard.
- Storm drains backing up into tubs, showers, or floor drains. When the city’s storm system is overwhelmed, the water finds the next available exit, which is often your lowest drain. This water is classified as category 3, meaning it may contain sewage.
- Carpet or drywall that has been wet for more than 24 hours. By the 48-hour mark, mold spores that were dormant in drywall and padding begin to activate. Houston’s humidity speeds that timeline up, especially from May through September.
- A water heater or washing machine failure that flooded multiple rooms. Clean water from an appliance is easier to treat, but the volume still requires industrial extraction and drying or you’ll be dealing with warped subflooring and musty odors for years.
- You smell earth or sewage after any water event. That smell tells you water soaked into something it should not have. It will not go away on its own, and masking it with air freshener just delays the fix.
Our Flood Cleanup Process
A tide mark is the line water leaves on a wall, and it is the first thing our technicians look for on every job. Finding that line tells us where the water stopped, which tells us exactly what needs to dry and what can be saved. Here is the sequence we follow on every flood cleanup in Houston:
- We answer, then we arrive. Your call goes to a live person at (325) 423-6800. We schedule the crew and tell you plainly what to expect, including whether you should shut off power to affected areas until we get there.
- Assessment and written price. Before any equipment comes off the truck, a technician walks the affected area, finds the tide mark, and checks hidden spaces like wall cavities and under cabinets with moisture meters. You receive a written price before any work starts. No exceptions, no surprises.
- Protection and removal. Shoe covers go on at the door. Drop cloths cover the floor before the first piece of equipment comes in. We photograph anything we move so we return it to the same spot. Flood-soaked drywall, padding, and insulation come out if they cannot be dried safely.
- Extraction and sanitizing. Truck-mounted and portable extraction units from Tidemark Water Damage Houston pull the standing water out. We then apply an EPA-registered sanitizer to all affected surfaces, especially when the water came from outside or from a sewer backup.
- Drying with professional-grade equipment. We place air movers and dehumidifiers from XPOWER and B-Air throughout the affected area. These machines move high volumes of air while pulling moisture down to a target range, and we check progress daily with moisture meters until every material reads dry, not just the surface.
- Photo of the clean-up, before we leave. Before the crew departs, we take a photo of the finished space and share it with you. You see exactly what was done and how it was left. The 365-Day Done Right Promise stands behind all of it: if it is not done right, we make it right.
Flood Cleanup Pricing in Houston
Flood cleanup pricing in Houston varies by the size of the affected area, the water category, and how long the water sat before extraction began. Most single-room flood cleanups run between $1,200 and $3,800 when the water is category 1 or 2 and the room is under 300 square feet. A multi-room flood from street water or sewer backup typically lands between $4,000 and $9,500, and a whole-home flood rarely comes in under $10,000 when full drywall removal, drying, and sanitizing are required. Houston homes with pier-and-beam foundations in neighborhoods like the Heights or Garden Oaks often cost slightly more for drying because the crawlspace underneath also needs attention, while slab-foundation homes in Clear Lake or Katy tend to dry faster once the standing water is out.
What moves the number most is the category of water. Clean water from a supply line is cheapest to clean. Gray water from a washing machine overflow adds sanitizing. Black water, which includes street flooding and sewer backup, requires the highest level of treatment and disposal. The second biggest factor is time: water that sat for two days costs more to remediate than water extracted within hours. Every Tidemark job comes with a written price before work begins, so the number you agree to is the number you pay. Estimates are free, and a call to (325) 423-6800 gets you a straightforward answer about what your specific situation will cost.
What Houston Floodwater Carries
Houston floodwater is not just rain. By the time it reaches your living room, it has flowed across streets, lawns, parking lots, and storm drains. It picks up motor oil, fertilizer, pet waste, and whatever else was sitting on the ground. In older Houston neighborhoods with combined or aging sewer lines, floodwater can also contain raw sewage. We treat all external floodwater as contaminated by default, which is why our process includes sanitizing, not just drying. For families with children and pets, this matters: we use pet-safe drying agents and cleaning products where there is a choice, and we make sure all contaminated materials are bagged and removed from the property on the same trip, not left in your driveway for days.
Protecting Your Belongings
Not everything soaked by floodwater has to be thrown away. Solid wood furniture can often be dried and refinished. Hard, non-porous items like dishes, tools, and plastic storage bins can be sanitized and saved. What typically cannot be saved after extended water exposure includes saturated mattresses, upholstered furniture that absorbed floodwater, and documents or photographs that sat wet for more than 48 hours. We ask before we move or touch anything, and we’ll tell you honestly what can be saved and what should be discarded, so you are making the decision with the facts, not a pressure pitch.
FAQs – Flood Cleanup
How long does flood cleanup take in Houston?
Most flood cleanup jobs in Houston take between 3 and 7 days from extraction to final drying, depending on the size of the affected area and how long the water sat before we arrived. The extraction itself is usually done the same day you call. Call (325) 423-6800 and we can give you a realistic timeline for your specific home.
Can you come today if my house flooded overnight?
Yes. We answer calls 24/7 with a live person, not a voicemail, and we schedule emergency flood cleanup in Houston the same day whenever possible, including nights and weekends. Water damage does not wait, and neither do we.
Does homeowners insurance cover flood cleanup in Houston?
Standard homeowners insurance typically covers water damage from inside your home, like a burst pipe or appliance failure. Flooding from outside water, including street flooding and bayou overflow, usually requires a separate flood insurance policy, often through the NFIP. We document every step of the cleanup with photos and moisture readings, which helps with either type of claim.
Is it safe to stay in my home during flood cleanup?
It depends on the water category and the size of the affected area. If floodwater from outside or a sewer backup entered your home, we recommend staying elsewhere until the contaminated materials are removed and the affected area is sanitized. For clean-water floods limited to one room, staying in the home is generally fine while drying equipment runs. We’ll give you a clear recommendation during our initial assessment, based on what we find, not a generic answer.
Do you use products that are safe for kids and pets?
Yes. Where there is a choice, we use pet-safe drying agents and cleaning products. We also run air movers on lower-decibel settings during school hours and nap time when possible, so the cleanup respects your family’s routine. If your child or pet has a specific sensitivity, tell us when we arrive and we will adjust.
How much does flood cleanup cost for a single room in Houston?
Single-room flood cleanup in Houston typically runs between $1,200 and $3,800 when the water is clean and the room is under 300 square feet. The written price you receive before any work starts is the price you pay. Call (325) 423-6800 for a free estimate, and we’ll walk you through what applies to your situation.
