When You Need Mold Removal
Mold isn’t always dramatic. Sometimes it’s a patch behind the bathroom vanity you noticed while reaching for a towel. Sometimes it’s a smell that comes and goes with the humidity. In Austin’s climate, where warm air and high moisture meet poorly ventilated homes built tight for AC efficiency, mold finds places to grow that homeowners often miss. Here’s what we typically hear from customers the week they call us:
- Visible spots or staining on drywall, baseboards, ceiling corners, or window sills. Black, green, gray, or even pinkish patches that weren’t there last season.
- A persistent earthy or musty odor in one room or closet, especially after rain or during humid stretches. If deodorizing doesn’t touch it, mold is often the source.
- A past water event that never got proper drying. A burst pipe in February, a roof leak during a spring storm, a slow AC condensate drip behind a wall. Mold can take weeks to show up after the moisture does.
- Allergy symptoms that ease when you leave home and return when you come back. Sneezing, coughing, itchy eyes, or worsened asthma can point to elevated mold spores indoors.
- Discoloration around AC vents or in bathrooms with poor exhaust. Austin’s humidity makes bathrooms and HVAC runs prime mold territory, especially in older homes from the 1970s and 1980s.
If you find mold in a contained area, say under a sink or on a small stretch of drywall, removal usually involves cutting out the affected material and cleaning the framing behind it. If the mold covers more than about 10 square feet, or if you suspect it’s inside walls or ductwork, the job shifts from removal into full mold remediation in Austin territory. We’ll tell you honestly which one you need.
Our Mold Removal Process
Mold removal isn’t spraying bleach on a wall and walking away. The spores have to be contained, the source of moisture has to be found, and the affected material has to come out. Here’s how we approach every removal job in Austin, step by step:
- Inspection and moisture tracing. Before we touch the mold, we find the water source feeding it. Using moisture meters and thermal imaging, we trace the damp area back to its origin, whether that’s a pinhole leak, a condensation line, or roof flashing that failed during the last storm. If we don’t fix the moisture, the mold comes back. Period.
- Containment and air control. We seal off the work area with plastic sheeting and run negative air pressure with HEPA-filtered air scrubbers. This keeps spores from drifting into your living room or your kids’ bedrooms while we work. The equipment we use comes from manufacturers like Dri-Eaz and Phoenix, the same brands you’ll find on large commercial restoration jobs.
- Removal of affected material. Mold doesn’t just sit on the surface; it roots into porous materials. We remove the affected drywall, insulation, carpet, or trim in sealed bags, cutting back to clean, dry material. Solid surfaces like concrete, tile, or studs that can be salvaged get HEPA vacuumed and treated with an antimicrobial agent registered for that use.
- HEPA filtration and cleaning. After removal, we run HEPA air scrubbers to pull airborne spores out of the room. We wipe down surrounding surfaces and verify the area before we even think about closing it up. This is where our IICRC and RIA training matters, knowing how to leave the space genuinely clean, not just looking clean.
- Drying and final verification. We take psychrometric readings (measuring temperature, humidity, and moisture content in the air and materials) to confirm the area is actually dry, not just dry on the surface. Once the numbers come back where they should be, we document the job with photos and give you a written record of exactly what was removed, what was treated, and what we found.
- Written guarantee. Every mold removal job comes with our 365-Day Done Right Promise printed on the work order. If the mold returns within a year and it’s tied to our work, we make it right at no charge. You don’t have to argue for a second visit; it’s part of the deal from day one.
Mold Removal Pricing in Austin
Here’s the honest answer on how much mold remediation costs. Most single-area mold removal jobs in Austin run between $350 and $1,200. The price depends on where the mold is, how deep it goes, and whether we need to cut into drywall, remove insulation, or pull up flooring.
- Small contained area (under a sink, inside a cabinet, small drywall patch): $350 to $650. This typically covers a single visit, containment, removal of the affected patch, treatment, and drying.
- Moderate area (one bathroom wall, a closet, a section of ceiling): $650 to $1,200. More material removal, longer HEPA filtration, and more labor make up the difference.
- Larger or harder-to-reach areas (crawlspace, attic, multiple rooms, mold in ductwork): $1,200 and up. Once we’re in a crawlspace in the summer or running new ductwork, the scope changes. We’ll give you a written number before we start, and that number doesn’t move unless you approve additional work first.
What affects the price: how much material has to come out, whether the area is contained and easy to reach or requires scaffolding and crawlspace work, and whether the moisture source needs repair as part of the job. You’ll get a written price before any demo starts. No estimate that balloons after we open the wall. That’s not how we work.
Call (361) 315-6142 and we’ll schedule a visit. The estimate is free, and we’ll tell you what we’d do and what it costs before you commit to anything.
FAQs – Mold Removal
Is mold removal covered by homeowners insurance?
Mold removal is covered by homeowners insurance only when it results from a covered water event, such as a burst pipe or storm damage, and the policy includes mold coverage. Many Texas policies cap mold coverage at $5,000 to $10,000. We can help you document the damage and the source for your claim. Call (361) 315-6142 and we’ll walk you through what your policy language means in plain English.
How much does mold removal cost in Austin?
Mold removal in Austin costs between $350 and $1,200 for most single-area jobs, with larger or harder-to-reach spaces running higher. The final number depends on how much material must be removed and whether the moisture source needs repair. You’ll get a written price before we start. Call (361) 315-6142 for a free estimate on your specific situation.
Can you remove mold in one day?
Most contained mold removal jobs in Austin are completed in one day, though the drying and verification process may add a second visit. If the area is small and the framing behind the drywall is dry, we can often finish removal the same day we start. Call (361) 315-6142 and we’ll tell you what a realistic timeline looks like for your home.
Is it cheaper to remove mold yourself?
Removing a small patch of surface mold on a non-porous surface can be done yourself with proper protective gear, but cutting out moldy drywall without mold inspection and testing to guide containment can spread spores through your home and make the problem worse. Most homeowners who call us after a DIY attempt spend more fixing the spread than the original removal would have cost. Call us first at (361) 315-6142 and we’ll give you an honest read on whether the job is worth your time or ours.
Who shows up at my door for a mold removal job?
With Marsh Water Damage Austin, you’ll know before the knock. Every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When they arrive, they’ll show a photo ID badge at the door, every time. It’s the Threshold Standard, and it’s how we remove the uncertainty along with the mold. Tobias Reyner, our owner, set that standard when we opened in 2005, and it hasn’t slipped since.
Why Austin Homeowners Call Marsh for Mold Removal
We’ve been removing mold in Austin since 2005, long enough to know that the mold itself is only half the worry. The other half is the stranger at the door.

That’s the Threshold Verified standard, and it’s printed on every work order alongside a written price and a written guarantee. If the repair isn’t right within 365 days, we make it right. No fine print, no argument.
Our equipment comes from Dri-Eaz and Phoenix, and our techs hold credentials through IICRC, RIA, and IFA. That matters because mold removal done wrong simply spreads the problem.
