AfterFlood Cleanup in San Antonio, TX
Flood cleanup in San Antonio usually costs between $2,800 and $7,500 for a typical single-room flood, with whole-house jobs running $12,000 to $30,000 depending on how long the water sat and what it touched. The work involves extracting standing water, cutting out soaked drywall and flooring, running commercial drying equipment for 3 to 5 days, and treating everything with antimicrobial agents so mold never gets a foothold. If you’re standing in water right now, call (325) 413-9949 – a live person answers around the clock, and we’ll give you a written price before a single tool comes off the truck.
This is the page for homeowners in San Antonio who just watched water pour in from a storm, a busted supply line, or a backed-up sewer and need to know what happens next. Wendell Restoration San Antonio handles every phase of Water Damage Restoration from first extraction to final drywall, because the faster water comes out, the less you pay. You can read more about how we approach the broader category on our Water Damage Restoration in San Antonio page, but if you want the flood-specific playbook and honest numbers, keep reading.
One thing you should know before anyone touches your home: Wendell puts the price in writing before work starts, sends you a live technician arrival time you can actually track, and texts before-and-after photos as the job progresses. No vague four-hour windows. No “we’ll see when we get there.” No surprises at the end. That’s the Relay Standard, and it’s how we’ve operated since 2006 as part of the Relay Home Co. family.

When You Need Flood Cleanup
Flood water is not the same as a small leak. It moves fast, carries whatever it touches, and seeps into places you can’t see. If any of the following sounds familiar, you need professional extraction and drying, not a shop vac and hope.
- Water covered your floors and sat for more than an hour. Even an inch of standing water wicks up into drywall, baseboards, and flooring within minutes. In San Antonio’s clay-heavy soil, slab foundations hold moisture longer than you’d expect, which means drying takes longer and requires real equipment.
- The water came from outside. Floodwater from storms, creeks, or street runoff carries bacteria, fertilizer, sewage, and whatever else it crossed. This isn’t a mop situation. It’s a contamination situation, and it calls for antimicrobial treatment after extraction.
- You smell something musty or earthy within 48 hours. That’s microbial growth starting. In San Antonio’s heat and humidity, mold can establish itself in as little as 48 to 72 hours after a flood. The clock is not your friend.
- Baseboards are swelling, paint is bubbling, or floors are cupping. Water is behind the walls and under the flooring. Surface drying won’t reach it. We use Injectidry systems to pull water from wall cavities and under cabinets without tearing everything apart first.
- Your HVAC ran during or after the flood. Air handlers push moisture and contaminants through the ductwork and into every room. We’ll inspect and dry the system as part of the scope, not as an afterthought.
- You’re in a low-lying neighborhood near Salado Creek, the San Antonio River, or Leon Creek. These areas flood regularly during spring storms and summer downpours. Homes in Alamo Heights, Olmos Park, and areas along Broadway are especially prone to stormwater intrusion when the ground is already saturated.
How Much Does Flood Cleanup Cost in San Antonio?
We give you a written price before any work begins, so you’ll know how much water damage restoration costs before equipment rolls in. But since you’re researching, here are the honest ranges we see across San Antonio, from Stone Oak to the South Side.
| Scope of Work | Typical Cost in San Antonio | What’s Included |
|---|---|---|
| Single-room flood, water extracted same day | $2,800 – $4,500 | Extraction, baseboard removal, drying equipment for 3 – 4 days, antimicrobial treatment, moisture monitoring |
| Two to three rooms, moderate saturation | $5,000 – $9,000 | Extraction, drywall removal up to 2 ft, flooring removal as needed, drying, treatment, daily monitoring |
| Whole-house flood, water sat 24+ hours | $12,000 – $30,000+ | Full extraction, extensive demolition, structural drying (7 – 10 days), HVAC drying, rebuild-ready cleanup |
| Sewage or contaminated water (category 3) | $7,000 – $20,000+ | Full PPE protocols, disposal of contaminated materials, deep antimicrobial treatment, air scrubbing |
| Moisture assessment and written scope only | Free | We assess, document, and hand you a written estimate. No obligation. |
What changes the price: the category of water (clean, gray, or black), how long it sat, what it soaked (hardwood costs more to save than tile), and whether walls need to be opened. In San Antonio specifically, slab-on-grade construction means water trapped under vinyl plank or tile often requires lifting the flooring to dry the slab itself – which adds cost but prevents mold a year from now.
Every quote includes our 365-Day Done Right Promise in writing: if the work isn’t done right, we make it right, no charge. And if a repair fails, the second visit is free. Call (325) 413-9949 and we’ll walk your specific situation over the phone before we even schedule.
Our Flood Cleanup Process
We follow IICRC protocols (the industry’s water damage standard) on every job, and we explain each step as we go. Here’s exactly what happens when you call.
- You call, a live person answers. Not a voicemail. Not a callback queue. 24/7, someone picks up, asks the right questions, and books your assessment. You get a live arrival time you can track, like watching a rideshare approach.
- We assess and document everything. A background-checked, uniformed technician arrives, maps the water’s path using moisture meters and thermal imaging, and photographs everything for your records. You get a written scope and a written price before any work starts.
- Extraction begins immediately. Truck-mounted and portable extractors pull the standing water out. Baseboards are removed, carpet pad is cut away, and saturated drywall is opened up so the structure can breathe.
- We deploy commercial drying equipment. Dri-Eaz and Phoenix dehumidifiers, XPOWER and B-Air air movers, and Injectidry mats for wall cavities and under cabinets. We use psychrometric drying – tracking the air’s temperature, humidity, and grain count daily – so we know when your home is truly dry, not just surface-dry. Most San Antonio floods take 3 to 5 days to hit the target.
- Antimicrobial treatment and air scrubbing. Every affected surface gets treated to stop mold before it starts, and HEPA air scrubbers run during and after drying to pull contaminants from the air. This step is non-negotiable on our jobs.
- We document the dry-down and hand you the proof. Before-and-after photos, moisture readings at each check, and a final written report showing the drying curve. If anything looks off when we’re done, the 365-Day Done Right Promise covers it.
This is the process we run on every flood job in San Antonio, whether it’s a garage in Cibolo, a basement-level room in the Medical Center area, or a slab home in Windcrest. The steps don’t change. The equipment doesn’t get downgraded for smaller jobs.
FAQs – Flood Cleanup
How long does flood cleanup take in San Antonio?
Most single-room flood cleanups in San Antonio take 3 to 5 days from extraction to final moisture verification. Larger jobs with extensive demolition and structural drying & dehumidification can run 7 to 10 days. San Antonio’s heat and humidity extend drying times compared to drier climates, which is why we track psychrometric readings daily instead of guessing. Call (325) 413-9949 and we’ll give you a realistic timeline for your specific situation.
Is flood cleanup covered by homeowners insurance?
It depends entirely on the source of the water. A burst pipe or water heater failure is typically covered under most standard policies, while rising stormwater or creek overflow usually requires a separate flood insurance policy. We work directly with your adjuster, document every step with photos and moisture readings, and provide the written scope your carrier needs. We don’t handle the claim for you, but we give you everything your adjuster asks for, which moves things faster.
Can you come today?
Yes. If you need water damage restoration near me in San Antonio, TX, we answer live 24/7 and in most neighborhoods we can have a technician on site within hours, not days. Flood water gets worse every hour it sits, so we prioritize flood calls over everything else. Call (325) 413-9949 now and tell us what happened – you’ll get a live person and a specific arrival window, not a guess.
Is it cheaper to just replace the drywall myself?
If the water was clean, from a supply line or a tub overflow, and you caught it within hours, you might save a few hundred dollars doing it yourself. But if the water came from outside, from sewage, or sat for more than a day, the risks of hidden mold and structural damage make professional cleanup the cheaper option long-term. A botched DIY dry-out can cost $15,000 or more in mold remediation a year later. We’ll tell you honestly if your situation is small enough to handle yourself – that’s part of the upfront transparency. Call (325) 413-9949 and describe what happened. We’ll give you a straight answer, including whether you need us at all.
Do you handle sewage backups and category 3 water?
Yes. We’re trained and equipped for contaminated water, which means full PPE, containment barriers, disposal of affected materials, and deep antimicrobial treatment. This type of work follows RIA and IFA standards in addition to IICRC protocols. If the water touching your skin came from a toilet, a sewer line, or street runoff, do not attempt cleanup yourself. Call (325) 413-9949 and we’ll walk you through what to do in the next 30 minutes while we head your way.
