Mold Remediation in Dallas typically costs between $1,500 and $6,000 depending on how far the colony has spread and whether it’s behind walls or under flooring. Most jobs in Dallas are completed within 3 to 5 days once containment is set. Marsh Water Damage Dallas has been handling mold problems across North Texas since 2005. When you call (432) 529-4284, a live person answers, we schedule a walkthrough, and we give you a written price before any work begins. No surprises after demo starts. Every technician who comes to your door is background-checked, identity-verified, and sent to you by name and photo before they arrive. That’s the Threshold Standard, and we’ve applied it to every visit since day one. Led by Tobias Reyner, our Dallas team holds IICRC, RIA, and IFA credentials, and we run professional drying and remediation equipment from Dri-Eaz, Phoenix, and XPOWER on residential jobs every week.
Mold Removal Service
A Mold Removal service is the physical extraction of visible mold growth from surfaces like drywall, wood framing, tile grout, and HVAC duct interiors. You need it when you can see discoloration, smell mustiness that won’t fade, or have had a water event that sat wet for more than 48 hours. Marsh Water Damage Dallas performs mold removal service using HEPA-filtered air scrubbers, antimicrobial treatments, and controlled demolition so spores don’t spread to clean rooms. Most residential mold removal service work in Dallas runs from $1,500 to $4,000 depending on square footage and what has to be cut out. We write the price down before we touch a wall.
Containment First, Removal Second
We set up negative air pressure and plastic containment barriers around the work area before any mold is disturbed. This prevents cross-contamination to bedrooms, living rooms, and hallways. Without containment, mold removal service actually makes the problem worse by launching spores into the air.
When Cleaning Isn’t Enough
Surface mold on tile or glass can sometimes be cleaned. Mold that has penetrated drywall, insulation, or wood needs to be removed, not wiped. We test the material and tell you honestly which category you’re in before pricing anything.
Restoration work we handle






Mold Remediation Services
Mold remediation services go beyond removal: they address the moisture source, treat affected materials, clean the air, and verify the structure is dry before we rebuild. You need full mold remediation services when mold has spread across more than 10 square feet, when it’s inside wall cavities, or when someone in the home has respiratory issues made worse by exposure. Marsh Water Damage Dallas provides mold remediation services with psychrometric readings (measuring the moisture in the air and materials) to confirm the area is genuinely dry, not just surface-dry. Typical mold remediation services in Dallas run $2,000 to $6,000 depending on scope. We include a written scope, a written guarantee, and our 365-Day Done Right Promise printed on every work order.
Moisture Mapping Before Anything Else
We use thermal imaging and moisture meters to find water you can’t see: inside walls, under floors, behind baseboards where North Texas humidity and slab foundations meet. Mold grows where moisture lingers. If we remove the mold but not the moisture source, it comes back. We don’t do return trips because we missed something.

Post-Remediation Verification
After removal and treatment, we run air sampling and surface testing to confirm spore counts are back to normal background levels for Dallas homes. We document the readings and give them to you. If something reads high, we fix it before we call the job done. That’s the 365-Day Done Right Promise in practice.

Professional Mold Removal
Professional mold removal means licensed technicians, containment equipment, HEPA filtration, and antimicrobial application instead of bleach and a sponge. You need professional mold removal the moment mold covers more than a few square feet, appears after a sewage backup or roof leak, or keeps returning after DIY attempts. Marsh Water Damage Dallas performs professional mold removal with commercial equipment from Dri-Eaz, XPOWER, B-Air, and Injectidry, the same machines used on large commercial losses. Professional mold removal in Dallas typically costs $1,800 to $3,500 for a contained single room, and more when multiple rooms are involved. We tell you the exact number before work starts.
HEPA Isn’t Optional
HEPA filtration captures 99.97% of particles down to 0.3 microns, which is smaller than most mold spores. We run air scrubbers throughout the job to pull spores out of the air, not just off the walls. A shop vac with a standard filter won’t do that.
Why Bleach Fails
Bleach kills surface mold but doesn’t penetrate porous materials like drywall and wood. The roots of the mold survive and regrow. Professional mold removal cuts out or treats the material itself. That’s the difference between removing mold and postponing it.
Mold Inspection
A Mold Inspection & Testing is a systematic check of a Dallas home for visible mold, hidden moisture, and conditions that make mold likely to grow. You need a mold inspection before buying or selling a home, after any water damage that wasn’t dried within 48 hours, or when someone in the house has unexplained allergies that improve when they leave. Marsh Water Damage Dallas offers mold inspection with moisture meters, thermal cameras, and air sampling when needed. A visual mold inspection in Dallas runs $200 to $600, and if we find mold during the inspection, we credit that amount toward remediation work. Tobias Reyner’s team documents everything with photos so you can see exactly what we see.
What We Check
We inspect bathrooms, kitchens, laundry rooms, attics, crawl spaces, HVAC units, water heater closets, and anywhere plumbing runs through Dallas slab foundations. We also check exterior grading and drainage, because water against the foundation is where a lot of indoor mold starts.
Testing vs. Visual Inspection
A visual inspection finds visible mold and moisture. Air sampling tells you what spores are floating in the air even when you can’t see colonization. We’ll recommend which one fits your situation and explain why, before you spend a dollar on testing.
Mold Removal Specialist
A mold removal specialist is a technician trained and certified in the science of mold: how it grows, how to contain it, how to remove it safely, and how to keep it from returning. You need a mold removal specialist when the issue involves structural cavities, HVAC systems, or large areas where improper removal would spread spores through your Dallas home. Every mold removal specialist sent by Marsh Water Damage Dallas holds IICRC or RIA credentials in applied microbial remediation, plus background checks and photo ID verification under the Threshold Standard. Specialist-led mold removal in Dallas typically runs $3,000 to $5,500 for whole-room remediation. The price includes containment, removal, treatment, drying verification, and a written guarantee.
Certification You Can Verify
IICRC certification means the specialist passed coursework and exams on microbial remediation standards. RIA credentials add training in applied structural drying. We’re glad to tell you which certifications your assigned specialist holds and what those credentials cover.
One Specialist, Start to Finish
We assign one mold removal specialist as your point of contact for the duration of the job. The person you meet at the walkthrough is the person who runs the project. You’re not passed between a sales rep and a crew you’ve never met.
Black Mold Removal
Black mold removal addresses Stachybotrys chartarum, the toxic-black-mold species, which appears as dark greenish-black patches and needs to be handled with full containment and HEPA filtration, not ordinary cleaning. You need black mold removal if you see dark staining in chronically damp areas like under sinks, around window frames, or on drywall after roof leaks, especially if anyone in the home has headaches, coughing, or worsened asthma. Marsh Water Damage Dallas performs black mold removal in Dallas using full containment barriers, negative air pressure, HEPA air scrubbers, and antimicrobial treatment, with air samples taken before and after. Black mold removal in Dallas generally starts around $2,500 and increases with the size of the affected area. We’ll give you a written price before any work begins.
Don’t Disturb It Before We Arrive
If you suspect black mold, don’t scrub it, don’t spray it, and don’t cut into the wall. Disturbing black mold releases spores into the air and spreads the problem. Close the door to the room and call us. We’ll assess it safely.
Testing Confirms the Species
Visual inspection can suggest black mold, but only lab analysis of a sample confirms Stachybotrys. We collect samples carefully and send them to an independent lab. The test results determine the treatment protocol we follow.
Mold Removal Contractor
A mold removal contractor is a licensed company, not a handyman, that carries insurance, follows IICRC standards, and provides a written scope and price before starting work. You need a mold removal contractor when mold has spread behind walls, under flooring, or into areas requiring controlled demolition and rebuild. Marsh Water Damage Dallas is a mold removal contractor in Dallas that has operated since 2005 as part of the Threshold Group family of restoration companies. As your mold removal contractor, we handle containment, removal, drying, antimicrobial treatment, and reconstruction so you deal with one company from first visit to final coat of paint. Full contractor-led mold removal and repair in Dallas typically costs $4,000 to $6,000 when rebuilding is included.
One Contract, One Crew
We don’t remove the mold and then hand you a list of other contractors to rebuild. Demo and reconstruction are in the same written scope. You sign one work order, and the same team finishes the job. That continuity cuts weeks off a typical multi-contractor timeline.
Insurance Paperwork, Handled
If your mold resulted from a covered water loss, we photograph everything, document moisture readings, and coordinate directly with your adjuster. Direct insurance billing is available. You get a copy of every document we send to the carrier.
Bathroom Mold Removal
Bathroom mold removal targets the most common indoor mold problem in Dallas homes: growth on shower grout, caulk, ceiling corners, and behind vanities where exhaust fans don’t move enough humid air. You need bathroom mold removal when scrubbing doesn’t kill the black or pink staining, when mold returns within weeks of cleaning, or when it appears on drywall above the shower. Marsh Water Damage Dallas performs bathroom mold removal with HEPA vacuums, antimicrobial solutions, and in cases where mold has penetrated drywall, controlled cut-out and replacement. Simple bathroom mold removal on tile and grout in Dallas runs $300 to $800. Mold behind drywall or under a floor runs $1,500 to $3,500 because it involves demolition and repair. We’ll tell you which category you’re in before quoting.
Ventilation Matters More Than Scrubbing
The root cause of most bathroom mold in Dallas is an underpowered exhaust fan or one that’s never run. Humidity from showers sits on surfaces and feeds mold. As part of our bathroom mold removal, we’ll check your fan’s CFM rating and duct run, and tell you plainly if it’s moving enough air for the square footage.
Caulk vs. Grout: Different Problems
Mold in caulk usually means the caulk has failed and moisture got behind it. Mold in grout often means water is penetrating the grout itself. We identify which material is failing and why, then fix it so you’re not recaulking every season.

AfterBrands We Service
The Dri-Eaz and Phoenix equipment we run in Dallas homes is the same gear used on commercial water losses and hospital projects. We service, maintain, and operate these units daily, which means your home gets commercial-grade drying power with residential attention to detail. Our team in Dallas has worked with Injectidry systems for wall cavities and hard-to-reach spaces, and B-Air air movers for airflow across wet materials. These are not rented machines we picked up this morning; they’re part of our standard fleet, maintained and tested under the Threshold Group standard.
Whether you have a small spot of bathroom mold or a full crawl space issue under a Dallas pier-and-beam home, we bring the right equipment and the trained people to run it. No brand loyalty needed on your part. The machines are there for one reason: to get your house dry, clean, and safe before we leave.
Signs You Need a Pro Right Now
- Musty smell that doesn’t go away. That smell is often the first sign of mold hidden behind walls or under flooring. If it lingers after you clean and air out the room, you likely have hidden growth that needs professional tools to find.
- Visible dark spots on walls, ceilings, or baseboards. Discoloration that spreads or darkens over a few weeks is actively growing mold, not a stain. The longer it’s left alone, the larger the remediation area becomes and the more it costs to fix.
- Water event that didn’t dry within 48 hours. If a pipe leaked, a roof dripped, or a Dallas storm pushed water under a door and you didn’t dry it within two days, mold has had time to start. The area may look fine on the surface while mold is active behind the paint.
- Recurring allergy symptoms at home that improve when you leave. Sneezing, coughing, itchy eyes, and headaches that fade when you go to work and return when you come home often point to airborne mold spores. A professional mold inspection with air sampling can confirm what’s in your air.
- Peeling or bubbling paint on interior walls. Paint doesn’t bubble without moisture behind it. That moisture is either an active leak or high humidity collecting on the wall, and both conditions feed mold growth inside the drywall cavity.
Our Process, Step by Step
- 1
Walkthrough and moisture mapping. We inspect your Dallas home room by room, checking visible surfaces and using moisture meters and thermal imaging to find water behind walls and under floors. We find the moisture source before we talk about removal, because removing mold without fixing the source is just postponing the next colony.
- 2
Written scope and fixed price. Before any work begins, you get a written document listing exactly what we’ll remove, what we’ll treat, what we’ll rebuild, and what it costs. No estimate that balloons after demo starts. No surprise change orders. If we find something unexpected, we stop and talk to you first.
- 3
Containment and removal. We set up negative air pressure and plastic containment around the affected area so spores don’t spread to clean rooms. Then we remove the damaged materials, HEPA vacuum surfaces, and bag contaminated debris for proper disposal per Texas environmental guidelines.
- 4
Treatment and drying verification. We apply antimicrobial treatments to remaining surfaces and run drying equipment until psychrometric readings (measuring the moisture in the air and materials) confirm the structure is genuinely dry. We document those readings and give them to you. Dry on the surface isn’t dry inside the wall.
- 5
Rebuild and post-testing. If we removed drywall, insulation, or flooring, we rebuild to match the existing space. Then we run air or surface samples as needed to confirm spore counts are back to normal background levels for Dallas indoor air. Every step is covered by our 365-Day Done Right Promise, and if anything isn’t right within a year, we come back and fix it at no charge.
How Much Does Mold Remediation Cost in Dallas?
Mold Remediation cost guide: in Dallas it runs between $1,500 and $6,000 for most residential jobs. Small, contained issues like bathroom mold on tile and grout cost $300 to $800. A single room with mold behind drywall typically runs $1,800 to $3,500. Whole-room remediation with rebuild averages $4,000 to $6,000. Black mold removal with lab testing and full containment starts around $2,500.
What moves the price: square footage of the affected area, whether mold is behind walls or only on surfaces, whether drywall and insulation need replacement, and whether the moisture source is an active leak or already fixed. Homes with pier-and-beam foundations in Oak Lawn or older Dallas neighborhoods sometimes have crawl space mold that requires different equipment and more labor. Slab foundation homes in North Dallas more often have mold behind baseboards from pipe leaks under the slab.
How to avoid overpaying: get a written scope with line items, ask whether air testing is included or extra, and be skeptical of any quote that doesn’t require a site visit. We can’t give you a real number over the phone without seeing the space. A free walkthrough and written estimate is the only honest way to price this work. Our estimates are free, written, and locked before any work begins.
If you’re comparing quotes, ask each contractor these three questions: What containments and air filtration are included? What’s your drying verification process? What happens if the mold returns within a year? We answer all three in writing on every job.
