Storm Damage Restoration in San Antonio - 24/7 Storm Response, On Site Fast

Trusted Storm Damage Restoration for San Antonio Homeowners

When a storm rips through San Antonio, it rarely arrives alone. High winds tear off shingles in Alamo Heights, flash floods push muddy water into homes near Salado Creek, and hail the size of golf balls shatters windows in Stone Oak. The water that follows is what causes the real damage, saturating drywall, warping floors, and creating the damp conditions mold needs within 48 hours. Marsh Water Damage San Antonio has responded to storm damage across Bexar County since 2005, including Storm Damage Restoration in San Antonio,, with teams dispatched the same day you call. If water is inside your home right now, call (325) 252-3917. A live person answers, and you’ll know exactly who’s coming before they knock.

Flood Cleanup

Flood Cleanup is the immediate removal of standing water and the drying of every surface it touched, and in San Antonio it’s a service most homeowners need at least once after a heavy storm season. Our crews respond with commercial extraction units that pull hundreds of gallons per hour, followed by high-volume air movers and dehumidifiers that dry framing and flooring to a measurable standard. Most residential flood cleanup jobs in San Antonio run between $1,800 and $4,500, with the final number depending on how far the water traveled and whether baseboards, carpet, or drywall sections need removal. Every job starts with a written price before any equipment enters your home.

Extraction Before Drying

Standing water keeps wicking upward into drywall and sideways under flooring as long as it sits. We remove it first with truck-mounted and portable extraction tools, then hammer out the moisture map so you can see exactly what’s wet and what’s not.

Documentation for Insurance

Our techs photograph every room, every water-damaged surface, and every step of the process. We coordinate directly with your adjuster so the scope of work matches the damage they see on record, not a summary written from memory.

Flooded House

A Flooded House is a home where water has moved beyond one room and compromised multiple spaces, often from a creek overflow, a failed sump, or a roof breach that went unnoticed overnight. In neighborhoods like Terrell Hills and Castle Hills, we regularly see flooding that starts in a garage or utility room and travels through shared wall cavities into living areas. The cost to restore a flooded house in San Antonio typically falls between $6,000 and $18,000 when multiple rooms have been affected, including water extraction, controlled structural drying, and reconstruction of saturated drywall and flooring. We provide that number in writing before the first cut is made.

Multi-Room Water Migration

Water doesn’t stop at the doorway. It follows the path of least resistance, which is often through wall plates, under tile, and into closets you haven’t checked. Our moisture meters locate water you can’t see, so we dry the house, not just the room where you first noticed the puddle.

Rapid Response Matters

A flooded house that sits unmitigated for 72 hours becomes a different job entirely. The difference between a $6,000 cleanup and an $18,000 reconstruction is often measured in hours, which is why our San Antonio crews are dispatched as soon as you call, with the tech’s name and photo sent to you before arrival.

Flood Restoration

Flood Restoration is the complete process of returning a water-damaged home in San Antonio to its pre-loss condition, and it goes far beyond drying things out. It includes controlled demolition of unsalvageable materials, structural drying verified by moisture readings, antimicrobial application where needed, and reconstruction of everything removed. A full flood restoration in a San Antonio home typically costs between $9,000 and $25,000 depending on square footage and how deeply the water penetrated, with the exact scope itemized before any work begins. Our team holds IICRC, RIA, and IFA credentials, and every restoration is backed by the 365-Day Done Right Promise in writing.

Controlled Demolition

Some materials simply don’t survive flooding. Saturated drywall crumbles, particleboard swells, and carpet padding becomes a sponge for contaminants. We remove only what’s unsalvageable, show you exactly what was cut and why, and never touch a wall that doesn’t need to come out.

Rebuild, Not Just Drying

Once the structure passes final moisture verification, we rebuild to code: new drywall, paint, trim, and flooring matched to your home. The crew that dries your house is the same crew that rebuilds it, so there’s no handoff between strangers.

Basement Flood Cleanup

Basement Flood Cleanup addresses the lowest point of your home, where gravity sends every drop of water before we get a chance to, and it’s a job we handle regularly in San Antonio’s older neighborhoods where below-grade rooms are common. Because basements sit below the water table during heavy rains, they flood fast and stay wet longer, which invites mold growth within two days if the air isn’t actively dried. Basement flood cleanup in San Antonio typically costs between $2,200 and $6,500, including pumping, dehumidification, and restoration of affected finishes. The price is agreed upon before our team starts any work, and it won’t change after demo begins.

Sump Failure Response

When a sump pump dies during a storm, the basement becomes a collecting bowl. We arrive with backup pumping capability and replace the failed unit only if that’s the cause, so you’re not paying for a restoration that doesn’t also fix what started the flood.

Moisture in Concrete and Masonry

Concrete looks dry long before it actually is. We use penetrating moisture meters to read the slab and foundation walls, then run dehumidifiers sized to pull moisture out of masonry, not just the air around it. Drying a concrete basement floor can take four to six days, and we verify it with numbers, not a hand on the surface.

Storm Damage Contractors

Storm Damage Contractors are the licensed and insured professionals who repair what storms break, from water-logged interiors to damaged roofs and broken windows, and Marsh Water Damage San Antonio fills that role for hundreds of homeowners across San Antonio, Converse, and surrounding areas every year. We’re not a general contractor who happens to do water damage; storm restoration is a core discipline, and our teams run commercial-grade drying equipment from Dri-Eaz, Phoenix, and Injectidry on every job. Storm damage restoration in San Antonio generally runs between $2,000 and $15,000 depending on whether you’re looking at water extraction alone or full structural repair, with pricing broken down line by line before work starts. Our standing 365-Day Done Right Promise means the repair is guaranteed for a full year, and if something isn’t right we come back at no cost.

One Team, Not a Rolodex

Storm damage usually means damage to your roof, your walls, your floors, and sometimes your contents. We handle the interior restoration and coordinate directly with your roofer and your insurance adjuster, so you’re not managing four different companies and hoping they communicate.

Threshold Verified Technicians

Every Marsh technician who walks a San Antonio job site is background-checked, identity-verified, and sent to you by name and photo before arrival. They show a photo ID badge at the door, every time. That’s the Threshold Standard, and it applies to every visit, not just the first one.

Storm Damage Cleanup

Storm Damage Cleanup is the urgent work that happens in the hours after a storm passes: removing water, clearing debris that’s already inside the home, and stabilizing the structure so secondary damage doesn’t spread through San Antonio’s humid air. It’s the difference between a house that dries and a house that grows mold behind its walls. Storm damage cleanup in San Antonio ranges from $1,500 for a single-room extraction to $12,000 or more when tree limbs have breached the building envelope and water has contaminated multiple levels. We give you a written scope and a written price before any work begins, no exceptions.

Debris and Water Together

Wind-driven rain often brings leaves, insulation, and roofing material inside with it. We remove debris and water in the same pass, because you can’t properly dry a room with wet cellulose piled in the corner feeding moisture back into the air.

Pet and People-Safe Drying

The drying process raises indoor temperatures and moves a lot of air. We’ll explain what to expect, where the equipment goes, and how long it’ll run, so your family can stay comfortable in the parts of the home that aren’t affected while we dry the parts that are.

Brands We Service

Marsh Water Damage San Antonio works with restoration equipment from Dri-Eaz, Phoenix, and Injectidry, the same commercial-grade systems used in large commercial losses, applied to residential jobs throughout Bexar County. Our technicians are trained on these platforms and understand how to position air movers and dehumidifiers for maximum evaporation without over-drying framing or creating secondary humidity problems in adjacent rooms.

We also work around the equipment already in your home: water heaters, sump pumps, HVAC systems, and the finishes they protect. Whether your home has a finished basement with painted drywall or an unfinished storage room with exposed framing, our moisture readings and drying strategy are tailored to the materials we find. If you have any other make or setup, our process adapts to it, not the other way around.

Signs You Need a Pro Right Now

• Water has been standing for more than 24 hours. After a day, standing water in a San Antonio home starts moving through drywall and subflooring. The cost to restore goes up every hour it sits, and the mold clock is already ticking.
• The water came from outside, not a clean pipe. Flood water from creeks, street overflow, or storm drains carries silt, bacteria, and whatever it picked up along the way. Category 3 water requires more than a mop and a fan; it requires antimicrobial treatment and controlled disposal of affected materials.
• You smell an earthy, musty odor that wasn’t there before the storm. That smell is microbial activity, and in San Antonio’s heat and humidity it can establish itself within 48 hours. By the time you smell it, the colony is large enough that surface cleaning won’t solve the problem.
• Drywall is soft, bubbling, or crumbling to the touch. Water-saturated gypsum loses structural strength fast. If a wall feels soft after a storm, the water has been in there long enough to cause real damage, and that section likely needs cutting out rather than drying in place.
• You can see water staining the ceiling below a storm-damaged roof. That’s water that has traveled through the roof deck, insulation, and drywall to get there. By the time it shows up as a stain, the cavity above is saturated, and it’s only going to spread until the source is sealed and the cavity is dried.

Our Process, Step by Step

1. 1
   Call and we answer. A live person picks up at (325) 252-3917, 24 hours a day, including holidays. You’ll describe the damage, and we’ll tell you what to expect in plain words: who’s coming, when, and what they’ll do first.
2. 2
   You meet your technician before they enter. We send you the name and photo of the technician assigned to your San Antonio job before they arrive. They’ll show a photo ID badge at your door. If the photo doesn’t match the person standing there, don’t let them in. That never happens, but the standard is yours to enforce.
3. 3
   Written assessment and moisture mapping. We walk the property with you, identify the water source, and map moisture readings using penetrating and non-penetrating meters. We’ll show you the map, explain what’s wet, and establish a drying plan with a realistic timeline.
4. 4
   Agreed price, signed before work starts. You get a written scope of work and a firm price. If the job grows because we find hidden damage, we stop, show you, and agree on a new number in writing before any additional work proceeds. No surprises.
5. 5
   Extraction, drying, and verification. We remove standing water, set drying equipment, and return daily to monitor progress. The job isn’t done until moisture readings confirm the structure is dry at its core. You get a final report, and your 365-Day Done Right Promise is printed on it.
