AfterHow Much Does Mold Remediation Cost in Dallas?
Mold Remediation in Dallas, TX typically costs $1,800 to $6,500 for a standard 100 to 300 square foot affected area in 2026. Small, contained jobs like a bathroom ceiling or a closet wall run $500 to $1,800, while attic or crawl space remediation, or mold throughout multiple rooms, can push the total to $8,000 to $15,000. Most Dallas homeowners pay around $3,200 for a mid-sized job that includes removal, treatment, and post-remediation verification.
At Dryden Restoration Dallas, we give you a written price before any tool leaves the truck, so the number we quote is the number you pay. We don’t change it at the door. If you’re looking at a musty smell in a Lakewood bungalow or visible growth in a Frisco attic, call us at (940) 468-1166 for a free estimate. A live person answers, day or night.

Mold Remediation Cost Breakdown (2026)
Rather than one lump price, mold removal in Dallas is built from distinct phases of work. You’re paying for the process, not just the spraying. Here’s how a typical Dallas job breaks down, with line-item ranges based on what we see across neighborhoods like Preston Hollow, Bishop Arts, Richardson, and Garland:
| Remediation Component | Typical Cost in Dallas (2026) | What It Covers |
|---|---|---|
| Inspection and moisture mapping | $150 to $400 | Visual inspection, moisture meter readings, and locating the water source that started the mold. Sometimes rolled into the job total if you hire the same company for remediation. |
| Containment and air filtration | $300 to $1,200 | Plastic sheeting, negative air pressure machines, and HEPA filters to keep spores from spreading to other rooms in your home. |
| Mold removal and surface cleaning | $700 to $4,000 | Physical removal of mold from drywall, wood, tile, and framing. Includes HEPA vacuuming and antimicrobial treatment of affected surfaces. |
| Demolition and debris disposal | $400 to $2,500 | Cutting out drywall, carpet, or insulation that can’t be cleaned. Includes bagging, transport, and disposal per local regulations. |
| Structural drying | $500 to $2,000 | When mold is caused by an ongoing leak or flood, we dry the structural wood and subfloor with professional-grade equipment, including Dri-Eaz and Phoenix dehumidifiers, before rebuilding. |
| Post-remediation verification | $200 to $600 | Visual confirmation and moisture readings to show the affected area is dry and mold-free. We do this on every job, not as an add-on. |
| Rebuild and restoration | $600 to $6,000+ | Replacing drywall, insulation, trim, and paint once remediation is done. This overlaps with full mold remediation and rebuild services in Dallas. |
Those are real numbers from the Dallas market. The biggest variable in 2026 remains the same as it was five years ago: whether the mold is only on the surface, or whether it has penetrated into drywall, subfloor, or framing. Surface mold on tile or sealed concrete is inexpensive to clean. Mold inside a wall cavity, or underneath a bathroom from a slow toilet leak that sat for months, is more involved because containment and rebuild become unavoidable.
One thing we won’t do is quote you a low teaser number, then stack add-on fees once the job is underway. The written price covers the scope we agree on. If we find something worse behind the wall, we stop, walk you through what we found, and put the revised number in writing before continuing. You approve it or you don’t. That’s how we’ve operated since Carl Brandt founded the company in 2005, and it’s the same approach today.
What Affects Mold Remediation Pricing in Dallas
Every home is different, but cost drivers in Dallas fall into a handful of categories. These are the six factors that most affect your final price:
- Square footage of the affected area. This is the biggest one. Mold behind a 4-foot-by-4-foot bathroom shower wall is far cheaper than mold that spans an entire attic deck or the crawl space under a pier-and-beam home. Dallas has plenty of both, and the older homes in Kessler Park and Lake Highlands tend to have tighter, harder-to-access crawl spaces than newer construction in McKinney or Prosper.
- Where the mold is. Accessibility changes labor cost. A moldy drywall section in an open garage is straightforward. Mold in a 3-foot-tall attic with blown-in insulation overhead means your technicians work in a hotter, tighter space. Dallas attics hit 130 degrees in August. That slows the work, increases safety precautions, and adds cost.
- What type of surface is affected. Non-porous surfaces like tile, glass, and sealed hardwood are cleaned and saved. Porous materials like drywall, carpet pad, fiberglass insulation, and acoustic ceiling tile nearly always come out, because mold roots embed in the material itself. Replacement of these materials is a cost line item, not an option.
- The water source behind the mold. If the source is a one-time event, like an overflowing tub or a Dallas ice-storm roof leak that has since been repaired, the remediation is simpler. If the source is ongoing, like a slab leak under a North Dallas ranch or a recurring flashing failure on a 1970s comp roof, we must fix the moisture driving the problem first, or the mold returns in months. That adds a plumbing or roofing step to the project.
- Containment complexity. Mold spores move through HVAC systems and open doorways. In a single-story home with a contained bathroom issue, containment is inexpensive. In a two-story home with a moldy HVAC duct in the ceiling chase, we need to seal off the affected zone, run negative air pressure, and filter the air we exhaust. That’s the difference between a $300 containment line and a $1,200 one.
- Post-remediation testing. Some Dallas homeowners ask for third-party air sampling after the job, which is an additional $300 to $700 depending on the lab and the number of samples. We recommend it for anyone with respiratory issues, immunocompromised family members, or a history of recurring mold. The visual and moisture verification is always included; independent lab testing is the optional step.
Mold Remediation Cost by Dallas Property Type
Different Dallas homes have different mold patterns. Here is what typically drives pricing in the property types we work in most often:
Single-Family Homes (Slab Foundation)
These dominate Dallas proper: East Dallas, Oak Cliff, Casa View, and the M Streets. Common problem areas include bathroom showers, kitchen sink bases, and water heater closets. Mold stays localized in most slab homes because there’s no crawl space below to move moisture upward. Typical cost: $1,200 to $5,500. The high end is usually a full gut-and-rebuild of a flooded bathroom or a slab leak that soaked carpet and baseboards before it was caught.
Homes with Crawl Spaces
You’ll find these mostly in older Dallas neighborhoods, particularly in Kessler Park, Oak Lawn, and parts of Irving and Grand Prairie. A dirt floor crawl space with high relative humidity breeds mold on the floor joists. Remediation in a crawl space means working in a confined area, often with encapsulation planning. Typical mold remediation for a crawl space runs $3,000 to $9,000, and the higher range usually includes a vapor barrier and dehumidifier installation to prevent recurrence.
Two-Story Homes
Plano, Frisco, Allen, and Rockwall have no shortage of two-story construction. The risk is moisture from an upstairs bathroom traveling down through the ceiling chase and showing up as a discolored patch on the first-floor ceiling. That means opening the ceiling from below and the wall from above, plus larger containment. Expect $2,500 to $8,000 for a typical upstairs bathroom leak with downstairs ceiling damage.
Townhomes and Condos
In Uptown, downtown lofts, and the mixed-use developments along the Dallas North Tollway, mold is often the result of a shared wall or a neighbor’s leak. Containment is easier in smaller square footage, but HOA coordination sometimes adds delay, not cost. A standard condo or townhome remediation runs $1,000 to $4,000.
How to Save on Mold Remediation
You should never compromise on a job that affects the air your family breathes. But there are legitimate ways to keep a Dallas mold remediation bill from growing without cutting corners:
- Fix the moisture source before you call us. If you know the dishwasher line is leaking or the toilet wax ring needs replacement, having that addressed first means our team doesn’t have to coordinate a plumber on your clock. It shortens the job and saves you a markup.
- Act when you first see it or smell it. A 10-square-foot mold patch caught early is a $500 to $1,200 job. That same patch left for one rainy Dallas spring can become a 100-square-foot problem behind the drywall. Mold grows faster in our humid months, April through October, and Dallas relative humidity regularly climbs above 70 percent in the early morning hours.
- Don’t tear into the moldy area yourself before we see it. Cutting open moldy drywall releases spores into the air and spreads contamination. It also destroys the moisture pattern that tells us where to look for the source, which can make diagnosis slower and more expensive.
- Ask for a phased written estimate. You want to see the inspection, containment, removal, drying, verification, and rebuild as separate lines. That lets you understand the cost structure. On smaller jobs, a contractor may roll inspection into the total. On larger jobs, insist on line items. We do this automatically.
- Get a free estimate first. This is the simplest one. Call (940) 468-1166 and we will walk you through likely cost ranges over the phone, then schedule an in-person assessment at no charge. A written price before any work begins is standard on every Dryden job.
- Don’t pay for unnecessary rebuild. Some remediation companies will remove wet drywall and then hand you a blank wall and a bill. We itemize the rebuild separately, so if you have a preferred contractor for finish work, you can handle that piece yourself. If you want us to do the full restoration, we quote it in advance.
How the Remediation Process Works
Knowing the mold inspection & testing and remediation process helps you understand the price. Here’s the step-by-step sequence we follow on every mold remediation job in Dallas:
- Inspection and moisture mapping. A technician walks your home, visually inspects the affected area, and uses a moisture meter to identify how far the moisture extends into the material. We’ll check relative humidity, or RH, which is a measure of how much water vapor the air is holding. Dallas homes in summer often run 60 to 75 percent RH indoors if the HVAC is undersized. Above 60 percent, mold can begin to grow on surfaces that sit damp for 48 hours or more.
- Written scope and price. You get a document that spells out exactly what we’ll do, what it costs, what is included, and what is not. The number you sign off on is the number you pay, unless you approve a change order in writing. We don’t do verbal add-ons. That’s the foundation of The Kingswell Way: say the price before the work.
- Containment setup. We seal the work area with plastic sheeting, run negative air pressure with HEPA-filtered air scrubbers, and cover vent openings so spores don’t circulate through the HVAC system.
- Removal of contaminated material. Porous materials with visible mold growth, typically drywall, baseboard, insulation, or carpet, are cut out and bagged inside the containment zone before they leave the area. We use HEPA vacuums on attachable surfaces and antimicrobial solutions on structural wood and framing that stays.
- Psychrometric drying. This is the industry term for measuring and controlling the moisture content in the air and materials after the water source is fixed. We use professional-grade equipment: Dri-Eaz dehumidifiers, Phoenix air movers, XPOWER fans, B-Air air scrubbers, and Injectidry systems for cavity drying. The goal is to bring the structural wood, subfloor, and wall cavities below the moisture level where mold can survive.
- Post-remediation verification. We visually confirm the affected area is clean and the moisture readings are back to a dry standard. You get a written summary of what we did and the readings we recorded. If any covered repair fails within 365 days, the Done Right Promise kicks in: we return and correct it at no charge. That’s in writing, on every job.
- Rebuild and finish. Depending on your scope, we replace drywall, insulation, trim, and texture, then paint. We leave the job site cleaner than we found it. If you handle the rebuild yourself, we hand the space to you prepped and dry.
Dryden’s Commitments: Written, Not Spoken
The Dallas restoration market is crowded, and a lot of companies say the same things. We don’t trade in general assurances. We trade in specific commitments that are documented on every single job:
- Written Price Before Any Work Starts. This is never optional, never verbal. We hand you a written scope and dollar amount before a tool comes off the truck. The number doesn’t change at the door.
- Named Arrival Window. When you schedule, we commit to a specific window. We come when we said we would. If something outside our control shifts the schedule, you hear from us, not a mystery dispatcher.
- 365-Day Done Right Promise. If any covered repair we make fails within one year, we return and make it right at no additional cost. This is documented, not verbal.
- Live Person, 24/7. Every call to (940) 468-1166 is answered by a human being. Not a voicemail prompt, not an answering service, not an after-hours recording.
- Background-Chcked and Uniformed Technicians. The person at your door has been verified, wears a Dryden uniform, and will identify themselves before entering your home. You’ll know exactly who you let in.
- Professional Equipment, Explained Plainly. We use Dri-Eaz, Phoenix, XPOWER, B-Air, and Injectidry systems, the same machines large commercial crews run, and we work to IICRC, RIA, and IFA standards. The acronyms refer to the Institute of Inspection, Cleaning and Restoration Certification, the Restoration Industry Association, and the International Fireproofing Association benchmarks for training and ethics. We’ll explain what that means for your home in plain English, not jargon.
FAQs – Mold Remediation Cost
How much does mold remediation cost per square foot in Dallas?
Plan on $12 to $30 per square foot for mold remediation in Dallas in 2026. The low end applies to surface contamination on accessible, non-porous areas, while the high end reflects porous material removal, containment, and rebuild. Most mid-sized residential jobs land at about $15 to $22 per square foot when you include all phases. For a precise number on your home, call (940) 468-1166 for a free estimate.
Is it cheaper to repair or replace moldy drywall?
Cutting out and replacing moldy drywall is almost always the right call, and it typically costs $400 to $1,200 per affected wall section in Dallas, including debris hauling. Trying to save moldy drywall with surface cleaning rarely works, because the mold’s root structure penetrates the paper face and gypsum core. Replacement is cheaper long-term than a second remediation in six months, which our 365-Day Done Right Promise would require us to correct for free.
Does homeowners insurance cover mold remediation in Dallas?
Insurance coverage depends on your specific policy language, but the most common Dallas pattern is: mold remediation is covered only when the mold resulted from a covered peril, such as a sudden pipe burst or storm-related water damage. Damage from slow leaks, groundwater seepage, or ongoing humidity is typically excluded. Many policies cap mold coverage at $5,000 to $10,000, with the cap rarely approaching the full remediation cost on a major job. We’ll give you a written scope and bill details that you can submit directly to your adjuster.
Can mold remediation be done the same day in Dallas?
Inspection, containment, and the start of removal can usually begin the same day or next day after you call, depending on our schedule that morning. A small contained job, like a bathroom closet with surface mold, can be completed in 4 to 8 hours. Larger jobs with structural drying take 2 to 5 days because the equipment must bring the moisture content down before rebuild. Call (940) 468-1166 and a live person will tell you what today’s schedule looks like.
How much does attic mold remediation cost in Dallas?
Attic mold remediation in Dallas runs $2,500 to $9,000. The spread is driven by two factors specific to this market: first, Dallas attics are vented differently depending on the era of construction, and older homes often have inadequate ventilation that traps warm, moist air against the roof deck. Second, the severity varies from light surface staining, which can sometimes be treated with cleanup and ventilation correction, to deep roof sheathing contamination that requires removal and interior surface treatment. A full attic job often includes air sealing and vent correction so the mold doesn’t return, which is part of the higher range.
