Get your free estimateFast, Reliable Mold Remediation Across New Braunfels
Mold remediation in New Braunfels typically costs between $1,200 and $4,500 depending on the square footage affected, where the moisture came from, and whether containment is needed. Most jobs we handle after river flooding or a slab leak are completed within three to five days, start to finish. If you’ve spotted staining on drywall, a musty smell you can’t place, or water that sat for more than 24 hours, call (325) 230-0537 and we’ll have a technician out the same day to assess what’s going on.
We know New Braunfels homes differently than a crew that just drives up from a big city. The limestone and pier-and-beam houses near downtown, the brick-veneer 80s builds off FM 306, the townhomes packed tight near Gruene with alley-load garages and shared walls. Each one moves moisture differently, and each one hides mold in its own way. That’s what we train for.
Why Tidemark Water Damage San Antonio Is New Braunfels’s Preferred Mold Remediation Company
Our Mold Remediation team works the New Braunfels market every week, because dispatch runs from our San Antonio office and the drive up I-35 is short. That means when the Comal or Guadalupe floods, we’re not figuring out the roads for the first time. We know which low crossings block access in Landa Park, which streets off River Road back up with tourist traffic in summer, and which neighborhoods need a truck that can get into an alley without scraping a fence line.
Rick Sumner, who runs our crews, has walked hundreds of crawlspaces in New Braunfels. He’s the first to say that a pier-and-beam foundation under a 1920s Gruene cottage has almost nothing in common with a slab home off Walnut Avenue. That local read on construction is why our written price always reflects what we actually find, not what a national playbook assumes.
Every mold job includes a written price before any work starts, shoe covers and drop cloths the moment a tech walks through the door, and a photo of the finished cleanup before we leave. The 365-Day Done Right Promise means if mold returns in the same area within a year, we make it right at no additional charge. No fine print. No phone tag. Just a real promise from a real crew.
Restoration work we handle






Mold Inspection in New Braunfels
Mold Inspection in New Braunfels is what we recommend as a first step when you can smell something musty but can’t see it, or when you’re buying or selling a home near the rivers and need documentation. A typical inspection here runs $250 to $600 depending on square footage and whether you need air sampling sent to a lab. We look at the obvious places first: water heater closets, under sinks, around windows that catch the morning dew, and any crawlspace or kneewall access you have.
What We Check Before We Quote
We check the tide mark. A tide mark is the line water leaves on a wall, and it’s the first thing our technicians look for on every job. In New Braunfels, after a flood event, that line often runs higher behind the beadboard or baseboard than a homeowner expects, because river water moves fast and wicks upward through gypsum and plaster.
When You Might Skip the Full Inspection
If you already see visible mold larger than a few square feet, an inspection is usually folded into the remediation quote. You won’t pay for two separate visits. We’ll identify the extent, the moisture source, and the removal scope, then hand you a written price on-site.
Mold Removal Specialist in New Braunfels
A Mold Removal Specialist in New Braunfels does more than cut out wet drywall, because your framing matters. In pier-and-beam homes, mold hides in subflooring, joist pockets, and behind limestone skirt walls where the air doesn’t move. Our specialists set containment with negative air pressure so spores don’t migrate into bedrooms or shared walls, then remove affected material to sound structure, treat what remains with antimicrobials, and dry the cavity fully before rebuild.
Containment in Tight Spaces
Many New Braunfels newer builds use alley-load garages. That’s where a water heater sits, and that’s where a first-floor leak becomes a wall cavity problem that climbs. We seal the garage door from the inside, run HEPA-scrubbed negative air, and keep the shared alley side closed so neighbors and kids aren’t exposed. It’s slower work. It’s the only way to do it right in attached housing.
After the Removal
We don’t just leave you with studs and say good luck. We dry past the tide mark using Dri-Eaz and Phoenix equipment, check moisture content with the same meters we used at inspection, and document before, during, and after. You get photos. Your insurance gets a clear record. You know exactly what was done and what it looked like when we finished.
Trusted Brands We Service in New Braunfels
Most restoration companies in New Braunfels use generic equipment. We run Dri-Eaz dehumidifiers and Phoenix axial air movers because they hold their performance in the humidity our summers deliver. Our techs carry IICRC, RIA, and IFA credentials, which means they’ve trained on the specific conditions we see here: floodwater, high dew points, limestone construction, and drywall that turns to sponge in 48 hours. When you call, you’re getting a crew that knows those machines and knows this town.

AfterCommon Mold Remediation Problems We See in New Braunfels Homes
- Floodwater wicking behind historic limestone. Downtown and Gruene homes with limestone skirt walls hide moisture that climbs from the soil after river flooding. You won’t see it from the outside, and a standard moisture meter on the floor won’t catch it. We probe the walls.
- Slab homes off FM 306 with hidden supply-line leaks. Copper pipes under slab-on-grade foundations, common in 1990s builds around Oak Run, develop pinhole leaks that feed mold behind baseboards for weeks before anyone notices. The first sign is usually a warm spot on the tile or a faint mildew smell in a hallway.
- Air-conditioned closets in humid summers. When an HVAC supply duct runs through a closet, condensation forms on the back wall during June through September in New Braunfels. By the time clothes at the back of the closet smell sour, the drywall behind them is usually colonized.
- Shared-wall townhomes near Gruene. A leak in a neighbor’s unit can send moisture through a common wall into yours. We see this after heavy tourist turnover, when a unit sat empty and a pan overflowed. Containment in these buildings is critical, because spore pressure moves through the shared framing.

FAQs About Mold Remediation in New Braunfels
Mold can start growing within 24 to 48 hours after floodwater enters a home in New Braunfels, because our dew points stay high and summer temperatures hit 100°F regularly. By the time a homeowners’ insurance adjuster schedules a first visit, a Category 2 flood situation can become a full mold bloom. We recommend calling us the same day water appears, even if you’re still waiting on your claim. We document everything for your adjuster.
Yes, you should have the crawlspace inspected, because river water wicks through soil and up into joists and subflooring in pier-and-beam homes. The floodwater can be gone from your yard in a day, but the moisture under your floor stays for weeks. In homes off River Road and around Gruene, we often find hidden mold behind limestone skirt walls weeks after the water receded. A crawlspace moisture check is usually under $200 and tells you exactly where you stand.
Yes, and we do it routinely in New Braunfels townhome communities around Gruene and along I-35. We seal the garage door from the inside with an airtight zipper system, run negative air pressure through a HEPA filter, and monitor the pressure so nothing escapes into a neighbor’s unit. The containment takes a couple of hours to set up correctly, and it protects your shared alley and your neighbors’ units during the whole job.
Category 3 water, often called black water, means the water carried sewage, river sediment, or chemical runoff, and everything it touched that is porous must be removed. Homes near Lake Dunlap and along River Road see Category 3 flooding when the river rises fast and carries mud, agricultural runoff, and debris. Drywall, carpet pad, insulation, and oftentimes lower cabinetry get removed, not just dried. We then sanitize the structure before any rebuild starts.
We find and fix the moisture source first, then dry the structure past the tide mark, which is the only way to prevent regrowth in limestone and pier-and-beam construction. In older New Braunfels homes, that often means addressing grading around the foundation, replacing failed vapor barriers in crawlspaces, and resealing the limestone skirt joints. Then we remove the mold, treat the surfaces, and document the moisture levels at completion. If mold returns in the same area within 365 days, we make it right under our Done Right Promise.
