Mold Testing in La Porte, TX

Bayfront homes, older frames

La Porte is a city of about 35,000 on the northwest end of Galveston Bay, roughly 25 miles from downtown Houston, beside the Port of Houston's Bayport Terminal. The town is known for many small 1940s frame houses, and its waterfront has a long storm record: hurricanes in 1900, 1915 and 1943 damaged the old Sylvan Beach resort area and other attractions. Older raised frame homes breathe humid air under the floor, and that crawl space is where hidden mold often starts. Newer slab homes have their own weak points, mostly around attic AC equipment, drain pans and supply ducts that sweat through the long cooling season.

What to do now

1. Look for the moisture source: roof, plumbing, AC drain or water under the house.
2. Don't spray, scrub or paint suspect areas before a test; it skews results.
3. Ask yourself what the test needs to answer, such as where the smell comes from or whether a past repair worked.
4. Hire an assessor who holds a TDLR mold assessment license and confirm the name on TDLR's license search.
5. If repairs follow, check permits with La Porte Planning & Development's Inspection Services Division before work begins.

Cost factors

Angi's Houston cost data reports inspection and testing averaging $453, with a low-to-high range of $245 to $845. Crawl-space access, the number of samples and any HVAC or wall-cavity sampling raise the cost; Angi's national figures put a surface swab test at about $200 to $300. If testing confirms a problem big enough for professional removal, the remediation must be done by a different company from the one that assessed it, so you'll be paying two firms. Renters dealing with dangerous or neglected buildings can contact La Porte Code Enforcement through Inspection Services or the La Porte Support app.
