Water Damage Repair
Water Damage Repair is the structural fix that follows water extraction and drying. Once the standing water is removed and the framing reaches target moisture content, repair work rebuilds what the water ruined: drywall, baseboards, flooring, cabinetry, and sometimes load-bearing floor systems. Most residential water damage repair in San Antonio runs between $1,200 and $4,500, though a flooded second-floor bathroom that soaked through a ceiling can push higher. At Marsh Water Damage San Antonio, we repair the full scope, never just the visible surface. Our Water Damage Restoration in San Antonio team writes the repair scope before any work starts, so you approve every line item first.
Structural Drying Before Patchwork
Repairing over a damp cavity is the most common cause of recurring water damage in San Antonio homes. We take psychrometric readings (measuring the moisture in the air and inside framing) to confirm the structure is genuinely dry before any drywall goes back up. If the framing isn’t dry, the repair will fail, and we won’t put our 365-day promise on a repair we know won’t hold.
Matching Materials, Not Just Replacing Them
Older San Antonio neighborhoods like Alamo Heights and Terrell Hills have wall textures, baseboard profiles, and tile patterns that big-box patches can’t match well. We source or replicate the right material so the repair blends with the rest of the room. A patch you can point to from across the room isn’t a repair; it’s a reminder of the damage.
Restoration work we handle
Water Mitigation
Water Mitigation is the emergency-phase work that stops the damage from getting worse, before the big repair decisions get made. It means stopping the source, extracting standing water, removing ruined materials that trap moisture, and setting professional drying equipment. In San Antonio, water mitigation on a typical single-room loss runs $800 to $2,800, depending on how much flooring and drywall has to come out. Marsh Water Damage San Antonio mitigates every job as if the adjuster will walk through tomorrow, because in many cases they will. We document everything with photos and moisture readings your insurance company can actually use.
Fast Containment, Fewer Replaced Materials
The difference between a $1,000 mitigation and a $6,000 one is often measured in hours, not days. Water wicks upward through drywall and sideways through slab-on-grade flooring quickly in San Antonio’s heat, especially in summer when indoor humidity is already high. We contain the water, cut the wicking line, and get air moving before the damage perimeter expands.
The Equipment Matters More Than You’d Think
We deploy commercial drying equipment from Dri-Eaz, Phoenix, and XPOWER, the same gear used on large commercial losses, applied to your spare bedroom. Low-end restoration outfits use box fans and hope for the best. We use axial air movers, LGR dehumidifiers, and hygrometers that tell us exactly when the air and materials reach dry standard.
Flooded Basement
Flooded Basement emergencies are less common in San Antonio than in northern cities, but when they happen, they tend to be severe because basements here are rarely designed for water. A flooded basement in San Antonio typically costs between $1,500 and $5,000 to extract, dry, and repair, with the final number driven by how much finished space sits below grade. Marsh Water Damage San Antonio treats every flooded basement as a containment job first, because water in a below-grade space doesn’t drain on its own and doesn’t dry on its own. Our team has worked in the older homes in Water Damage Restoration in Boerne where basements doubled as storage or utility rooms, and we know exactly what water does in those spaces.
Submersible Pumps Before Extraction Rigs
If water depth in a basement exceeds a couple of inches, we lead with submersible pumps to move the bulk water out fast, then switch to extraction wands and truck-mounted units for the remaining film and saturation. This is a two-stage process that saves hours of standing-water time. Standing water in a basement is doing damage to foundation walls, stored items, and anything with a pilot light the entire time it sits.
Below-Grade Drying Takes Patience
Concrete basement walls and slab floors hold moisture long after the visible water is gone. We set desiccant or LGR dehumidifiers and leave them running with scheduled check-ins, tracking the daily moisture curve until the numbers plateau at dry standard. Pulling equipment too early is the single most common reason basements smell musty a month after a “professional” dry-out.
Water Extraction
Water Extraction is the physical removal of standing water and saturated-surface water using specialized pumps and extraction wands, and it is the first thing a professional should do on any meaningful water loss. For a typical San Antonio living room or kitchen flood, water extraction alone runs $400 to $1,200, with more for heavy saturation or multiple rooms. Marsh Water Damage San Antonio arrives with truck-mounted extraction capability and portable units for tight access. We don’t leave puddles and drop fans, which is the classic handyman approach that fails every time. Extraction matters because standing water keeps wicking while it sits.
Carpet, Pad, and Hard Surface Extraction
Each surface extracts differently. Carpet can sometimes be saved with aggressive extraction and drying, but the pad underneath almost never can. Hardwood floors pull water through the seams, so we extract with weighted tools that draw moisture up through the gaps. Tile can look dry while water sits in the thinset and substrate beneath. We extract by surface type, not with a one-size wand.
Why the First Hour Changes the Bill
A loss that gets professional extraction within the first hour has a materially better outcome than one that waits four hours. Water in San Antonio’s clay-heavy soil doesn’t drain well away from a slab, which means slab saturation is a real concern in north-side neighborhoods like Stone Oak and further out toward Water Damage Restoration in Selma. Fast extraction reduces the water load before it migrates into places you can’t see.
Emergency Water Removal
Emergency Water Removal is the round-the-clock response that puts eyes, hands, and equipment on a water loss immediately, because water doesn’t pause for business hours. A live person answers at (325) 252-3917 at 3 a.m. on Christmas morning, and we dispatch from our San Antonio base to most metro-area homes within 60 to 90 minutes. Emergency water removal generally runs $450 to $1,400 for a first-response visit that includes initial extraction and equipment setup. The price is written before work starts, even at 3 a.m. That’s a Marsh promise, and it’s printed on the work order you sign on the spot.
What the Emergency Crew Does in the First Hour
The first hour is diagnostic: find the source, stop it, map the water perimeter, and take baseline moisture readings. Then we extract. Then we set containment and drying equipment. You’ll see the plan on paper before we start moving furniture, not after.
Solo Homeowners and Families With Young Kids
If you’re home alone or managing young children during a water emergency, the last thing you need is an unknown crew at your door. Our Threshold Verified protocol sends you the technician’s name, photo, and verification status before they arrive, and every tech shows a photo ID badge at the door. No exceptions.
Flood Damage Restoration
Flood Damage Restoration covers the full arc from emergency response through final rebuild when water comes from an outside source: storm surge, creek overflow, or the kind of heavy San Antonio downpour that sends water over a low entry threshold. Costs run from $2,000 on a small garage intrusion to $20,000-plus when structural drying, flooring replacement, and trim work are required. Marsh Water Damage San Antonio uses the same IICRC-driven flood damage protocols whether the water came from a failed supply line or a flash flood in Leon Valley. The source matters for safety classification, and we treat floodwater as potentially contaminated until the testing tells us otherwise.
Category 3 Water Requires a Different Playbook
Floodwater that enters from the ground is Category 3: it carries soil, sewage, and biological contaminants. That means removing and disposing of porous materials like carpet pad, some drywall types, and insulation, then sanitizing what remains. Our team wears proper PPE, contains the work area, and documents the disposal trail for your insurance adjuster.
Working Direct With Your Adjuster
Flood damage restoration is where insurance paperwork gets complicated. We photograph every step, write scopes in language adjusters recognize, and coordinate directly with your insurance company so the claim moves. You don’t have to translate what a restoration tech meant. We write it in plain English the first time.
Water Damage Cleanup
Water Damage Cleanup is the removal of water, debris, and ruined materials, plus the cleaning and sanitizing of the affected area, and it’s the phase where a homeowner can most easily be oversold. In San Antonio, water damage cleanup typically runs $600 to $1,800 for a contained loss with minimal material removal. At Marsh Water Damage San Antonio, cleanup means exactly what we write in the scope: remove, dispose, clean, sanitize, dry. Nothing extra. If we recommend additional work, we show you the readings and the photos that justify it. You’ll never get a vague “might as well” upsell from our crew.
Dealing With an Overwhelmed Homeowner’s List
When water has soaked a hallway, a closet, and the corner of a bedroom, it’s hard to know what’s lost and what’s salvageable. We walk the space with you, tagged-item by tagged-item, and tell you what can be dried in place, what needs to come out, and what should be disposed of. You make the final call on every item.
Sanitizer and Antimicrobial Application
After the removal work, we treat the affected surfaces with an antimicrobial agent to prevent mold establishment, especially in San Antonio’s warm-season humidity. This isn’t mold remediation, but it’s the step that stops a water loss from becoming a mold loss on our watch.
Emergency Water Damage Restoration
Emergency Water Damage Restoration is the complete immediate package: extraction, drying, and mitigation performed as soon as the water is discovered, not scheduled for next Tuesday. San Antonio homeowners typically pay $900 to $2,500 for emergency water damage restoration on a single-room loss, with the equipment rental period included. The phone at (325) 252-3917 rings through to a live person in San Antonio 24 hours a day, not a voicemail. Tobias Reyner, who leads our restoration team, has built the company around one rule: the emergency crew gets dispatched while the customer is still on the phone, and that crew arrives with a written scope, not a blank contract.
Same-Day Dispatch From Our San Antonio Base
We’re not routing calls to a call center in another state. When you describe the loss, the person on the phone is in San Antonio and can dispatch from our local base to your part of town, whether that’s Kirby, Windcrest, or Universal City. Typical arrival in the San Antonio metro is 60 to 90 minutes from the end of the call.
What “Emergency” Does Not Mean
Emergency does not mean you lose the right to a written price and a clear scope. It does not mean the crew starts swinging hammers before you’ve seen the numbers. Marsh Water Damage San Antonio does emergency work without emergency pricing games. The same written-price rule applies at midnight as it does at noon.

AfterBrands We Service
We service and deploy professional restoration equipment from Dri-Eaz, Phoenix, XPOWER, B-Air, and Injectidry on residential losses throughout San Antonio. Dri-Eaz LGR dehumidifiers and Phoenix axial air movers are the workhorses of our drying fleet, chosen because they deliver measurable drying curves over days, not guesses over hours. We use Injectidry panel drying systems for the cases where water has migrated into wall cavities or under hardwood floors, because that system puts negative pressure exactly where the water is hiding.
Our technicians hold credentials from the IICRC, RIA, and IFA, which means they’ve passed the certifying bodies that set the restoration industry’s standards. Whether your equipment need is our concern or you’re just wondering if X brand is actually better than Y, we can help with a straight answer.
Signs You Need a Pro Right Now
- Water is still migrating. If you can see a dark line growing on drywall, water is moving through the material. Every hour that line advances means more drywall gets cut out later. A pro stops the migration at the source and dries the perimeter.
- You smell something earthy, not just damp. Damp smells like wet laundry. Earthy or musty smells mean biological activity has started, and in San Antonio’s heat, it starts fast. That smell is a warning that remediation work, not just drying, may be needed.
- Baseboards are swelling or separating from the wall. Swollen baseboards mean water has saturated the lower wall cavity. Behind every swelled baseboard is a cavity that needs to dry before mold establishes. Surface drying won’t touch it.
- Flooring feels soft or spongy underfoot. A soft spot in a wood floor or a spongy feel under carpet means the subfloor has absorbed water. Subfloors don’t dry on their own in San Antonio’s climate. Trapped moisture there leads to rot and creaking floor systems.
- The water came from outside. Storm water, creek overflow, and yard runoff carry soil, fertilizers, and biological contaminants. This water is classified differently from a clean supply line break, and it needs a different cleanup protocol, not just drying.
Our Process, Step by Step
- 1
Source stop and safety check. The first thing we do is stop the water at its source if it’s still flowing, then shut off any electrical risk in the affected area. We won’t stand in water and run power tools, and we won’t leave a live source while we start drying. Safety comes before cleanup, every time.
- 2
Assessment and written scope. We map the full water perimeter with moisture meters and thermal imaging, then write the scope of work and price on a sheet you sign before any equipment gets unloaded. The price covers extraction, equipment, monitoring, and the planned material removal. Nothing is verbal.
- 3
Extraction and material removal. We pump standing water, extract saturated carpet and pad, and cut out drywall and insulation that can’t be dried in place. The removal line is determined by the moisture readings, not by guesswork. We show you the readings as we go.
- 4
Drying with monitored equipment. We set air movers, dehumidifiers, and targeted drying systems, then come back daily to take psychrometric readings until the structure reaches dry standard. You’ll see the daily numbers shift toward dry. When the numbers plateau at the right level, we pull the equipment, not before.
- 5
Repair, rebuild, and the 365-Day Promise. Once everything is dry, we repair what we removed, matching materials to the existing room. The finished work is covered by our 365-Day Done Right Promise, printed on the work order, with a free second visit if anything is not right within a year.
How Much Does Water Damage Restoration Cost in San Antonio?
Water damage restoration in San Antonio runs on a wide range because the scope changes with the water source, the materials affected, and the hours passed before a pro arrives. A simple water extraction on a kitchen with tile floor and minimal drywall damage typically runs $400 to $1,200. A single room with drywall removal, drying equipment, and repair will land between $1,500 and $4,500. A whole-home flood with structural drying, flooring replacement, and full rebuild can range from $8,000 to $25,000 or higher. We give one written price before work starts, not a range that balloons after demo begins.
What moves the number: the water category (clean water is cheaper than Category 3 flood water, which needs disposal and sanitization), how many rooms the water reached, whether finished flooring has to come out, and how long the water sat before a pro arrived. You avoid overpaying by getting an extraction and assessment done faster rather than slower, and by hiring a company that writes the scope before cutting anything open. Our free estimate includes the full assessment, the moisture mapping, and a written line-item price. No charge for the visit, no obligation to book.

Frequently Asked Questions About Water Damage Restoration in San Antonio
Water damage restoration is the complete process of removing water, drying the structure, cleaning the affected area, and rebuilding what the water ruined. It includes extraction, dehumidification, material removal, sanitization, and repair, all done to the standard set by the IICRC. In San Antonio, the process typically takes three to seven days for drying plus additional time for repairs, and a written scope should be provided before any work begins.
Most residential water damage restoration jobs in San Antonio finish the drying phase in three to five days, with repairs taking another one to three days depending on what was removed. Drying time depends on the materials affected, the amount of water, and San Antonio’s ambient humidity. We take daily psychrometric readings and only pull drying equipment when the numbers confirm the structure is dry, not on a calendar schedule.
Costs range from about $400 for a simple extraction with no material removal to $25,000 or more for whole-home floods with full rebuilds. Most common single-room losses in San Antonio land between $1,500 and $4,500. Marsh Water Damage San Antonio provides a written price before any work starts, and the estimate is free. Call (325) 252-3917 for a no-obligation assessment.
