Finding mold in your Houston home is unsettling. The humidity here in Harris County means a small leak behind a bathroom wall or under a kitchen sink can turn into a real problem within days. Tidemark Water Damage Houston has handled our Mold Remediation in Houston, The Woodlands, Pearland, League City, and every neighborhood in between since 2006. We are independently owned and operated, working to the Cedarwell Care Promise, which means one thing above all: a written price before any work starts. Every technician is IICRC-credentialed, background-checked, and arrives in uniform with shoe covers and drop cloths loaded on the truck. Call (325) 423-6800 any time, day or night, and a live person will answer.
Mold Removal Service
Mold Removal Service is the physical removal of visible mold growth from surfaces in your home, from drywall and framing to tile grout and carpet backing. You need this service when you can see mold, smell a musty odor that won’t go away, or have confirmed moisture in a wall, ceiling, or floor cavity. In Houston’s climate, mold rarely stays on the surface. Our team removes the visible growth, cleans the affected area with professional-grade treatments, and dries the underlying materials past the tide mark so the mold does not come back. Most bathroom or closet mold removal jobs in Houston run between $500 and $1,800, and you will see the written number before we start.
Surface Mold on Drywall
We cut out and bag affected drywall, clean the framing behind it with wire brushes and professional antimicrobial products, and check the cavity for hidden moisture. The removed material goes straight into sealed bags and out through the nearest exit, never through your living room. Drop cloths cover the floor from the doorway to the work area before the first cut is made.
HVAC and Duct Mold
Houston air conditioning runs nine months out of the year, and the evaporator coil is a place mold loves. A mold removal service on your HVAC system starts with an inspection of the coil, drain pan, and supply plenum. We recommend cleaning and fogging the ductwork when mold is present in the system, and we’ll show you photos of what we found before we recommend anything.
Restoration work we handle






Mold Remediation Services
Mold Remediation Services go beyond simple removal. Remediation is the full process of correcting the conditions that allowed mold to grow in the first place: stopping the moisture, containing the affected area, removing the contaminated material, and treating the surrounding space so spores are not carried into the rest of the home. You need this level of service when mold covers more than about ten square feet, when it has gotten inside a wall or ceiling cavity, or when someone in the household has allergies, asthma, or a weakened immune system. A full mold remediation service in a single Houston bathroom typically runs $1,200 to $3,500. Larger areas with multiple rooms run $3,500 to $8,000 or more, written out before any work begins.
Containment and Negative Air
We seal the work area with plastic sheeting and run HEPA-filtered air scrubbers on the XPOWER line to keep mold spores from moving through the rest of your house. The containment area stays under negative air pressure the entire time drywall comes out and gets bagged. This is the difference between removing mold and spreading it.

Drying Past the Tide Mark
A tide mark is the line water leaves on a wall. It tells us exactly where moisture traveled, and we dry past that line, not just to it. Our technicians use professional-grade equipment from Dri-Eaz, Phoenix, and B-Air, with moisture meters checking the framing every few hours until readings are dry. We do not call a job done until the numbers say it is dry.

Professional Mold Removal
Professional Mold Removal means licensed, credentialed technicians doing the work instead of a handyman with a spray bottle. When you hire a pro, you get containment, air scrubbing, proper disposal, and documentation of what was found and what was done. You need professional mold removal whenever mold is inside a wall, ceiling, floor, or HVAC system, or when the affected area is larger than a bath towel. In Houston, a professional mold removal job for a small closet or under-sink area runs $800 to $2,000. A full room runs $2,500 to $6,500, with the written price delivered before we start.
Certified Technicians, Real Credentials
Our technicians hold IICRC, RIA, and IFA credentials, the recognized standard for mold and water restoration work. That means they passed written exams and field experience requirements, and they follow the industry standard of care on every job. Rick Sumner, who leads our Houston team, reviews every mold removal scope before the crew arrives.
Documented Before and After
We take photos of the affected area before we start, during the work, and after the cleanup is complete. Before the crew leaves, you get a photo of exactly what was removed and how the space was left. That photo set is yours, useful for insurance claims and for your own records.
Mold Inspection
Mold Inspection & Testing is a systematic search for visible mold, hidden moisture, and the conditions that let mold flourish in a Houston home. You need an inspection when you smell something musty but cannot see the source, when you have had a leak or flood in the past year, when you are buying or selling a home, or when someone in the family has unexplained allergy symptoms indoors. A mold inspection in Houston typically runs $250 to $600. If remediation work follows the inspection, we credit the inspection fee toward the job.
Moisture Mapping and Thermal Imaging
We use moisture meters and thermal imaging cameras to find damp spots behind walls, under floors, and above ceilings without tearing anything open. In Houston’s older neighborhoods like Aldine and South Houston, we regularly find slow plumbing leaks inside wall cavities that have been wet for months. The thermal camera shows us the cold spots where moisture is hiding.
Air and Surface Sampling
When a homeowner needs to know what kind of mold is present, we can take air and surface samples and send them to an independent lab. Black mold, or Stachybotrys, requires a lab test to confirm. The lab report tells us and you exactly what is in the air, which shapes the scope of the remediation plan.
Mold Removal Specialist
A Mold Removal Specialist is a technician whose entire job is mold: finding it, removing it, and keeping it from coming back. You need a specialist rather than a general contractor when the mold is in a structural cavity, when it has returned after a previous attempt, or when your insurance adjuster wants documentation from a credentialed remediation firm. In Houston, working with a mold removal specialist for a standard bathroom or closet job runs $1,000 to $3,000. Complex multi-room jobs run higher, and you see that written number before we begin.
Experience in Houston’s Climate
Houston humidity does not let up. A specialist knows that mold behind a bathroom vanity in Tomball is often fed by a slow pinhole leak in a copper line, not by shower steam. We have seen thousands of Houston homes with the same patterns: mold at the baseboards of east-facing walls, mold in closets that share a wall with a bathroom, mold at ceiling corners near A/C supply registers. That local experience shapes where we look first.
Insurance Documentation Support
When your mold removal specialist documents everything, your insurance conversation changes tone. We photograph every step and write the scope in plain language that adjusters accept. We work directly with your insurance on the scope and the documentation, so you do not have to translate remediation jargon to a claim representative.
Black Mold Removal
Black Mold Removal is the careful removal and disposal of Stachybotrys chartarum and other dark-pigmented molds that can trigger respiratory symptoms, especially in children, older adults, and anyone with asthma. You need black mold removal when testing confirms Stachybotrys or when dark, slimy patches appear on drywall, ceiling tiles, or areas that have been wet for more than a few days. Black mold removal in Houston typically runs $1,500 to $5,000 depending on the size of the affected area and whether the mold has gotten into framing or insulation. The written price is in your hands before we pull on gloves.
Full Containment Protocols
Black mold removal uses the same containment as any full remediation, but we are stricter about sealing every seam and running HEPA air scrubbers continuously. The work area stays under negative air pressure until the last bagged piece of drywall is out the door. Our technicians wear full PPE, and we treat every removed surface as hazardous material from the moment it is cut to the moment it hits the sealed bag.
Post-Removal Verification
After black mold removal, we run the air scrubbers for an additional 24 to 48 hours while we monitor the air with a particle counter and moisture meters. We can recommend a third-party post-remediation verification test from an independent lab if you or your insurance company want extra assurance. You get that recommendation in writing, not as a surprise add-on.
Mold Removal Contractor
A Mold Removal Contractor is the company you hire to manage the entire mold job from start to finish, including containment, removal, cleanup, and coordinating with your insurance when needed. You need a licensed contractor rather than a single technician when the job spans multiple rooms, when plumbing repairs are needed before remediation can begin, or when your mortgage company or HOA requires a formal scope of work. In Houston, hiring a mold removal contractor for a single-room job runs $2,000 to $5,000. Whole-floor remediations run $6,000 to $15,000, always with a written scope before work starts.
Written Scope, Agreed Before Work
Our contractors write the full scope in plain language: what gets removed, what gets cleaned, what gets treated, and what the job will cost. You sign that before we bring the first piece of equipment through your door. No surprise line items at the end, no “we found more and had to.” If we do find more during the work, we stop, show you, and hand you a revised written scope before continuing.
Plumbing and Structural Coordination
Mold is a symptom of water, and water usually means a plumbing or flashing problem that needs a fix. A mold removal contractor coordinates with licensed plumbers and carpenters so the leak gets repaired and the damaged area gets rebuilt. We manage the sequence: stop the water, remove the mold, dry the structure, then rebuild.
Bathroom Mold Removal
Bathroom Mold Removal is the most common mold service we perform in Houston homes because bathrooms here combine daily moisture with poor ventilation in older construction. You need bathroom mold removal when you see black or brown spots on the ceiling, along the tub surround, behind the toilet, or under the vanity. Most bathroom mold removal jobs in Houston run $800 to $2,500, depending on whether the mold is surface-level or has gotten inside the drywall and insulation behind the tile.
Exhaust Fan and Ventilation
Mold on the bathroom ceiling is often tied to an exhaust fan that is undersized, clogged, or venting into the attic instead of through the roof. We check the fan and duct as part of every bathroom mold removal service. If the fan moves under 50 CFM or vents into the attic, we will recommend a fix, in writing, with a price, before we touch anything else.
Compact Spaces, Full Protection
Bathrooms are small, which means plastic containment goes up fast and the work stays contained. We lay drop cloths from the bathroom door to the closest exterior exit, so removed moldy drywall never crosses your hallway carpet. Shoe covers go on at the door, and the work area gets HEPA-vacuumed before we break down containment.

AfterBrands We Service
Our crews work with professional-grade air movers and dehumidifiers from XPOWER and B-Air on mold remediation jobs across Houston. We run XPOWER HEPA air scrubbers during containment and use their axial air movers inside the work area to push dry air into wall cavities after removal. The B-Air units we use are rugged, quiet for their class, and hold up in the humid conditions that define mold work in Southeast Texas.
We also use Injectidry panels and their vacuum systems to dry wall cavities and under-cabinet spaces without cutting open more drywall than necessary. Whether you have an existing unit from one of these brands or any other make, we can work with what is in your home and bring the right equipment for the job.
Signs You Need a Pro Right Now
- You can see mold on a wall, ceiling, or floor. Visible mold means there is more behind it you cannot see. The spores are already in the air, and in Houston’s humidity, the colony grows by the day.
- You smell something musty and cannot find the source. That smell means mold is growing somewhere hidden, often inside a wall cavity or under flooring. A moisture meter and thermal camera will find the wet spot without tearing your home apart.
- You had a leak or flood in the last 60 days. Houston plumbing leaks and storm flooding leave moisture in places that do not dry on their own. If a wall stayed wet for more than 48 hours, mold has probably started. An inspection now costs less than remediation later.
- Paint is bubbling, peeling, or staining on an interior wall. Bubbling paint means moisture pushing up from inside the wall. That moisture feeds mold that you will not see until the paint comes off.
- Someone in the home has unexplained allergies or breathing issues indoors. Symptoms that improve when you leave the house and worsen when you return often point to indoor mold. In a home with kids or pets, we treat that as a call for a full inspection and moisture survey, not a guess.
Our Process, Step by Step
- 1
Inspection and moisture mapping. The crew arrives, puts on shoe covers, and walks the affected area with you. We use moisture meters and a thermal camera to map where water has traveled, looking for the tide mark on every surface. You see the findings before any work begins.
- 2
Written scope and price. We write the full scope in plain language: what will be removed, how the area will be contained, what equipment we will run, and what the job costs. You get that written price before we bring tools in. No work starts until you approve it.
- 3
Containment and air scrubbing. We seal the work area with plastic sheeting, set up HEPA air scrubbers, and pull negative air on the space. Drop cloths go down from the work area to the nearest exit. Your floors and furnishings stay protected as a standard step, not an upsell.
- 4
Removal, cleaning, and drying. Moldy drywall, insulation, and carpet come out in sealed bags. We clean the remaining framing and surfaces with professional antimicrobial treatments, then run air movers and dehumidifiers past the tide mark until the moisture meter reads dry. This can take 3 to 5 days depending on the size of the job.
- 5
Documentation and walk-through. Before we leave, we photograph the finished space and walk you through what was done. You get a photo of the clean-up before the crew departs. The 365-Day Done Right Promise covers the work long after we have driven away.
How Much Does Mold Remediation Cost in Houston?
A typical mold remediation in Houston runs between $1,200 and $3,500 for a single bathroom or closet, as detailed in our Mold Remediation cost guide. Surface mold removal in a small area starts around $500, while a full room with containment and cavity drying runs $2,500 to $6,500. Whole-floor remediation in a Houston home runs $6,000 to $15,000, depending on the size of the affected area and how much drywall, insulation, and flooring must be removed.
What affects the price most is how far the moisture traveled. Mold behind one vanity is a one-day job. Mold behind the vanity, through the shared wall, and into the adjacent bedroom framing is a different job entirely. The second big factor is whether plumbing repairs are needed before drying can begin. A third factor is whether your insurance covers the work, which changes the scope and the documentation requirements. The written estimate you get from us includes everything: labor, equipment, disposal, and the post-remediation verification. No surprise line items at the end. Call (325) 423-6800 for a free estimate, and we will walk you through the exact numbers for your home.

Frequently Asked Questions About Mold Remediation in Houston
Mold remediation is the full process of containing the affected area, removing moldy materials, cleaning and treating the remaining surfaces, and drying the structure so mold does not return. Remediation differs from simple cleaning because it addresses the moisture source and the hidden mold inside wall, ceiling, and floor cavities. In Houston’s climate, remediation usually includes professional drying equipment running for several days after removal is complete.
Most single-room mold remediation jobs in Houston take 3 to 5 days from equipment setup to final documentation. Small surface mold jobs can be done in one day. Larger projects with multiple rooms or HVAC involvement can run 7 to 14 days. The drying phase is what takes time; we do not rush it, because moisture left in framing means mold comes back.
Mold remediation in Houston typically costs $1,200 to $3,500 for a single room, with small surface jobs starting around $500 and whole-floor work running $6,000 to $15,000. The written price you approve before work starts is the price you pay. Call (325) 423-6800 for a free estimate on your exact situation.
Yes, we work directly with insurance adjusters and provide the photo documentation and written scope they need to process a mold claim. The documentation we generate throughout the job, including before and after photos and moisture readings, aligns with what adjusters expect from a credentialed remediation firm. We will help you understand what your policy covers and what it does not.
Safety is the core of how we work. The affected area is sealed under negative air containment, HEPA air scrubbers run continuously, and the crew wears full PPE. We use pet-safe drying agents and antimicrobial treatments where there is a choice, and we can run equipment on lower-decibel settings during school hours and nap time. Shoe covers and drop cloths keep your living spaces clean throughout the project.
You do not need to move furniture or clear the affected room; we handle that with drop cloths and containment. Keep kids and pets out of the immediate work area while containment goes up. If you have any personal items in the affected room, we will ask before we move or touch anything, and we will protect what stays in place.
Every mold remediation job we perform in Houston is covered by the 365-Day Done Right Promise. If the restoration is not done right, we make it right. That promise stands long after the crew has left, and it is in writing on every job, not just in marketing copy.
