Between the cedar pollen blowing off the Hill Country, summer humidity that never quite leaves, and dust from the construction that seems to be happening on every San Antonio street, the air inside a San Antonio home works hard for its living. Your ducts collect all of it, quietly, until the vents start telling the story.
In San Antonio we serve every neighborhood — Stone Oak, Alamo Ranch, the Medical Center area, King William, Monte Vista, Tobin Hill, the Pearl and Southtown, Terrell Heights, Denver Heights, Highland Hills, Harlandale, Woodlawn Lake, Beacon Hill, and everywhere inside Loop 410 and out to Loop 1604.
Simple, honest, and done in one visit.
We look inside the ducts, coils, and handler and show you clear photos of any growth we find.
Mold needs moisture. We identify whether it's condensation, a drain issue, or a leak feeding the growth.
You get a written plan and firm price before any remediation work starts.
Affected areas are cleaned and treated, then re-inspected and photographed so you can verify the result.
Every home is different, so we inspect first — free — show you photos of what we find, and give you one firm written quote. The price we quote is the price you pay.
📞 Call (210) 790-3600Mold spores circulating through your air can aggravate allergies and asthma, especially for kids and anyone with respiratory issues. The right response is a proper inspection — in your San Antonio home we'll show you photos of exactly what's growing before recommending anything.
It depends on how far the growth has spread, so we inspect first — free — and give you a firm written quote. You'll never get a scare-tactic number from us; you'll get photos and a plan.
Not if the moisture source is fixed. In San Antonio's humidity, condensation control is half the job — that's why every remediation includes finding and addressing where the moisture is coming from.
Light surface growth on metal ducts often responds to a deep cleaning and treatment. Mold inside fiberglass duct lining is different — that material usually needs replacement. We'll show you which situation your San Antonio home has, with photos.
Most San Antonio duct mold jobs take a day. Larger systems or combined replacement work can take longer — your written quote includes a clear timeline.
