How to Choose a Mold Removal Company in San Antonio, TX
San Antonio homeowners have one meaningful advantage when hiring a mold company, and most never use it: Texas actually licenses this trade, and the license is publicly searchable. That single check screens out a surprising share of the operators who knock on doors after a Flash Flood Alley storm. This guide covers how to run that check, what to ask beyond it, and the behaviors that should end a sales conversation. Ask all of it of us too — San Antonio Mold Pros would rather answer hard questions than win on a low number that grows later.
Use the Texas License Lookup Before Anything Else
Texas is in the minority of states that regulate mold work. Under the state's mold assessment and remediation rules, administered by the Texas Department of Licensing and Regulation, remediation on projects at or above a defined size threshold requires a licensed remediator, and TDLR publishes a searchable license database anyone can use.
So ask for the license number and look it up yourself, on the state site, before signing anything. Confirm the name on the license matches the company on your estimate. Homeowners working on their own property are exempt from licensing, which is why a small patch you handle yourself is perfectly legitimate — the requirement applies to contractors you hire.
A company that gets evasive when asked for a license number has answered the question.
What Storms Bring Besides Water
San Antonio sits in Flash Flood Alley, where a single stalled thunderstorm cell can dump enough rain to put water into homes that have never flooded. Within days of any significant event, unfamiliar trucks start working the affected neighborhoods.
Some of those crews are legitimate and busy. Others are following weather across the state and will not be reachable when a warranty question comes up next spring. Local address, local references, and a verifiable Texas license are the practical filters, and none of them take more than a few minutes to check.
Be especially wary of anyone offering to cover or discount your insurance deductible. That practice is illegal in Texas, and a contractor comfortable breaking that law is telling you how they will treat the parts of the job you cannot see.
The Questions That Reveal Real Process
Ask how they will locate the water source. In our area the usual suspects are AC condensate lines during a cooling season that runs most of the year, plumbing under slab foundations stressed by expansive clay soil, and storm intrusion around roofs and windows. A company that talks only about killing mold and never about finding water is selling the wrong thing.
Ask whether they use containment and negative air. Ask which materials come out versus get cleaned, and why — under IICRC S520, saturated porous materials like drywall and carpet pad generally come out, while hard surfaces can be cleaned.
Ask what you receive at the end: moisture readings, photographs, and a written scope. Those documents are what an insurer or a future buyer will want to see.
Comparing Estimates Without Getting Fooled
Insist on an on-site inspection before any number. Nobody can scope hidden moisture in a slab-on-grade home from a photograph, and a phone quote is a marketing device rather than an estimate.
When you have two or three bids, compare what each one proposes to open, remove, and dry rather than the totals. A bid that is thousands cheaper usually plans to leave a wall closed. That is not a discount; it is a different, smaller job that may not solve the problem.
Finally, notice who tells you that you might not need them. The EPA suggests homeowners can often handle contained areas under roughly ten square feet themselves. A company willing to say so has just shown you how it handles the jobs it does take.
