Mold Testing in Deer Park, TX

Why would a Deer Park house need testing at all?

Deer Park is a city of about 34,500 people roughly 21 miles from downtown Houston, bounded on the north by the Houston Ship Channel and home to large industrial plants. Its homes face the same pressures as the rest of the region: humid air most of the year, AC systems that run for months and sweat at the air handler and ducts, and heavy rain on flat clay ground that drains slowly. Mold tends to start in places you don't look, such as behind a washing machine, under a sink cabinet or around an attic drain pan. When you smell it but can't find it, sampling can narrow the search. When the source is obvious, such as a dark patch spreading across a bathroom ceiling, your money is better spent fixing the leak and getting the damaged material handled.

How do I read the results?

Mostly by comparison. The assessor takes an outdoor air sample as a baseline, then indoor samples in the rooms that concern you. If indoor counts run well above outdoor counts, or one mold type shows up indoors that barely appears outside, that points to an indoor source. EPA notes there are no federal limits for mold spores, so beware of any report that labels a number as simply safe or dangerous. The color of a mold says nothing reliable about its risk either.

Who should do the testing?

You may sample your own home. Anyone you pay must hold a TDLR mold assessment license; look the name up on TDLR's license search. If removal is needed, the assessor writes the protocol and a different company holding a TDLR remediation contractor license does the work, because Texas law forbids one company doing both on the same project. Angi's Houston cost data reports inspection and testing averaging $453, with most jobs between $355 and $563.
