We are usually called into a home or business for one or more of the following reasons: Recent Water Damage Visible Growth Strange Smell Health Complications Looking For Peace of Mind Real Estate Transaction We help people in all of the above situations find out not only if they have a problem, but also where the source is. What most restoration companies don’t want you to know is that not all mold is dangerous. Truth of the matter is mold is all around us and every indoor environment has acceptable levels. Any inspection that is done without testing is simply a guess at what is going on with your indoor air quality. Our service is so valuable because our air and surface samples offer hard evidence about what is going on in your home or business. Any respectable mold remediation company who is suggesting a home or business needs professional intervention should support the idea of a third party company like MI&T coming in to do an inspection and mold testing. Even when it is known that a problem is present, customers still benefit from involving us in the process. Our samples collection lets you know exactly what is going on gives a clear picture of PRECISELY what needs work. Determining how far a problem has spread is crucial in determining the size of a work area. If we can contain the work area, you can be sure you’ll save on your restoration cost.

Here at Healthy Air Duct, we believe the quality of air in our customers homes and businesses are of the upmost importance, not only for your health, but also for your HVAC unit. Dirty air ducts can make the air in your home or business dirtier than the air outside. We work hard and we work around the clock to provide you with service day or night. You can trust our company to go above and beyond for each of our customers. Call or send us a message now to schedule a Free Consultation!

"I thought that I would be paying about the price for their duct cleaning "special," which was $199 but ended up with a bill of $719.80. They added on extra charges for cleaning the return air duct, main unit, coil wash, and especially the fog machine, which took 5 minutes and ran $139. When I objected to this item initially, Nick told me that it was very important, I suspect because it generated the most profit. I admittedly authorized the work so that blame is on me. The ducts had never been cleaned in 49 years, which is why I went ahead with the whole package. The technicians worked hard and fast but allowed spray paint to fall on the the kitchen appliances. I only wish to warn future customers not to expect to get away for $199."

FAQs for mold & toxic material test projects in Houston, TX

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
