Musty smell, dark spots, an old leak that never quite dried out — WQB Mold Removal gets to the root of it and fixes San Antonio properties the right way.
Call +1-844-578-1604
Most of our San Antonio technicians spent years in water damage restoration before specializing in mold, so they understand exactly how a small leak turns into a much bigger problem.
Negative-air machines, HEPA scrubbers, moisture meters, and borescopes go out on every San Antonio job, whether it's a closet or a whole basement. We'd rather over-equip a small job than show up under-prepared and need a second visit to finish it properly.
We coordinate directly with insurance adjusters and San Antonio-area contractors so you're not stuck managing three different companies during one repair.
A lot of San Antonio property owners have already paid someone once for a remediation job that didn't actually hold, and that history shapes how carefully we document our own work.
Some mold problems are obvious. Most aren't — here's what usually tips people off.
Candles and sprays mask it for an hour, but a true mold odor comes right back — that's usually the giveaway. It's often strongest near a closet, vent, or crawl space hatch. A lingering odor after cleaning is usually the strongest single signal something is active behind the scenes.
Water stains — even faded, years-old ones — mean moisture reached somewhere it shouldn't have. Box fans rarely reach moisture trapped in subfloor or wall cavities. We've seen plenty of San Antonio homes where a "fixed" leak from years ago turned out to be the real culprit.
Kids and older family members often react first, since they're more sensitive to airborne spores. A symptom pattern tied to one specific room is a strong clue. Anyone with asthma or existing respiratory sensitivity tends to notice mold-related symptoms earliest and most severely.
Staining around an HVAC vent often means condensation is forming inside the ductwork itself. A phone photo can help our office gauge urgency before you even schedule. Don't wait for a bigger patch to appear before calling — early inspection is almost always cheaper.
From one bathroom to a flooded crawl space, the response scales to match what's really there.
A burst pipe or roof failure overnight in San Antonio can get a crew dispatched before sunrise. We document everything with photos on arrival, which helps if you're filing an insurance claim. We also flag any structural issue on the spot so you know what else may need attention once the water is gone.
Bathrooms, basements, and attics each get a method suited to that specific environment in your San Antonio home. Affected materials are bagged and removed per protocol, not tossed loose. Every San Antonio home gets treated on its own terms — a 1920s foundation and a new-build slab don't call for the same approach.
Retail spaces and offices in San Antonio, TX usually need work scheduled around business hours to limit disruption. We'll work evenings or weekends when that's what keeps a San Antonio business running. We're comfortable scoping a job across several units at once when a San Antonio, TX property manager needs one point of contact.
Air and surface samples identify the species present before we ever propose a plan. Reports typically return within a few business days. A written inspection report works for real estate transactions, refinancing, or simple peace of mind about a San Antonio property.
Attic mold often traces back to bath fans venting into the attic instead of outdoors. Encapsulation can be bundled into the same visit to save a second trip. We often trace a musty smell upstairs back to the crawl space, even in San Antonio homes where the living area looks spotless.
For chronic humidity, we design a long-term control plan rather than a one-time patch. Some San Antonio, TX clients schedule an annual check, especially in older homes. We'll suggest specific, practical fixes rather than a generic maintenance checklist.
No vague timelines — here's exactly what a San Antonio job looks like.

Describe what you're seeing and smelling and we'll get a tech on the calendar, often same-day for San Antonio. Let us know roughly when the issue started. If it's urgent, say so — dispatch prioritizes active water and sudden discovery over routine checks.
This step tells us what's actually going on, not a guess. Nothing gets decided before you understand it. Photos from the inspection go into your file so you have a record of exactly what we found.
Negative air pressure keeps spores from spreading to the rest of the San Antonio property. We keep the space as tidy as the job allows. Daily wrap-up notes are available on request for longer San Antonio jobs.
You'll get a written report for your records or your insurer. We walk the space with you before anyone signs off. You keep a copy of the clearance report for your own records or for a future buyer.
We explain each line item over the phone if you want to walk through it before committing to anything.
Dispatch across San Antonio, TX typically runs same-day for active issues, since we staff enough local techs to avoid a two-week backlog.
You'll walk away with lab results and a written scope, not just our word for it.
If regrowth tied to our workmanship shows up within the warranty period, we return and fix it at no extra charge.
Small San Antonio-area crews like ours live and die by reputation, which keeps us straightforward about scope, pricing, and realistic timelines.

We put our promise in writing because peace of mind should come standard, not as an upsell.

The questions we hear before nearly every job.

Most San Antonio calls get a tech same-day, with active emergencies bumped ahead of routine inspections. Mention active water intrusion when you call so we can flag it urgent. Scheduling load can shift day to day, so calling early in the morning often gets you the earliest slot.
We quote the full scope after inspection, and that number holds unless the scope changes. If we find extra damage once a wall's open, we stop and get your approval first. We've heard plenty of horror stories about mid-job upcharges from other San Antonio contractors, and that's exactly what our pricing model is built to avoid.
Emergency dispatch runs 24/7 for situations where a day's delay would make things worse. We coordinate directly with plumbers or roofers when the water source needs stopping first. If you're unsure whether your situation counts as an emergency, call anyway — our dispatcher can help you decide.
Results typically land within a few business days as a written report. We'll walk you through what the report actually means, not just hand over a page of Latin names. We use the same independent lab for every San Antonio job so results stay consistent and comparable over time.
Some policies cover mold tied to a sudden pipe burst but exclude gradual humidity issues. We're glad to speak with your adjuster directly if that helps. Every San Antonio, TX policy reads a little differently, so double-checking your specific mold and water-damage language ahead of time saves headaches later.
Timeline depends on square footage and whether structural materials need replacing. Drying time after extraction can add a day or two before remediation even starts. We'll tell you upfront if a San Antonio job looks like it's going to run longer than typical, rather than letting the timeline slip silently.
We may recommend staying elsewhere for extensive whole-house treatment, especially with asthma or mold sensitivities in the household. We'll say so honestly rather than downplay it to keep the job simpler. Most San Antonio clients are surprised how livable the rest of the house stays during a contained job.
We recommend keeping children and pets clear of the containment zone until clearance testing passes. Once clearance testing comes back clean, the space is safe for normal use again. We take extra care around nurseries, playrooms, and anywhere pets spend most of their time.
We fix the moisture source, not just the visible growth — treating symptoms without the cause almost guarantees regrowth. We'll also give practical ventilation or dehumidifier advice for your San Antonio property. Our warranty covers workmanship-related regrowth specifically, and we'll explain exactly what that means for your job before you sign anything.
Our dispatcher can walk you through what an initial visit covers. Availability sometimes tightens during peak humidity months across San Antonio, TX. We'd rather talk it through for five minutes than have you wait on something that turns out to be minor — or miss something that isn't.
"Removal" implies eliminating mold entirely, which isn't realistic since spores exist naturally everywhere; "remediation" means bringing levels back to a normal, safe range. Any company promising 100% removal is overselling — outdoor and indoor air both carry some spore count. We'd rather explain this clearly upfront than let a San Antonio customer expect something no company can actually deliver.
Bleach may remove surface staining but rarely reaches spores embedded in porous materials like drywall or subfloor. For small, non-porous surfaces a simple cleaning may be fine — anything on drywall, wood, or carpet usually needs a professional look. If you're not sure which category your situation falls into, send us a photo and we can usually tell you over the phone.
