Mold Remediation & Removal in Houston, TX

Those are national figures. We publish no prices for Houston: no sourced data supports them, and a number invented for a city is worse than no number. The full comparison is on mold removal cost and inspection and testing cost; the number for your house comes from the provider after they have seen it.

If you rent in Texas, the first thing to know is that mold is not named in the statute. A landlord’s repair duty covers conditions that materially affect the physical health or safety of an ordinary tenant, and the examples the law spells out are raw sewage, flooding, broken heating or cooling, and lack of potable water. Mold has to be shown to meet that standard rather than simply being pointed at.

The practical route is an inspector. A local building or health official confirming the condition is one of the ways the law recognises, and it turns an argument into a document. Before any of the tenant remedies apply you also have to be current on rent, give the landlord proper notice, and allow a reasonable time for the repair.

What the city will and will not do in Houston

Before you call anyone at the city, know where its line is. The Houston Health Department states that it does not conduct mold inspection or testing; what it may do is address the contributing factors that fall under minimum standards. For inspection or testing it points residents to TDLR.

So the complaint that gets traction here is about the water, not the growth: a leak, standing water, an envelope that is not keeping rain out. Report that, and the mold is your evidence rather than your charge.

Texas is one of the few states that licenses this work directly. TDLR requires a licence for mold-related activities, with an exemption for projects smaller than 25 contiguous square feet, and it does not allow one company to carry out both the assessment and the remediation on the same project. Asking for a licence number here is not awkward, it is how the system is meant to work.

Houston gets more rain than any other metro on our list: 49.77 inches a year across 64 days, at an average temperature of 69.9°F. Warm air holds more moisture than cold air, so the same inch of rain leaves a building damp for longer here than it would in Denver.

That combination — frequent wetting and a warm envelope that dries slowly — is why Houston work so often turns out to be larger than it looked. The question a provider should be answering is not what is on the surface but how far the moisture travelled through the materials behind it.

Where to look first here: crawl spaces and the underside of floors. Houston builds often sit low, the ground stays damp, and that combination does more damage over a year than any single storm.

Just under half the housing predates 1980. In a climate this wet, an older envelope has had more rainfall pass over it than almost anywhere else on our list.

The humidity measurement matches the rainfall: 70.6% on average, second only to San Diego among our twelve. Wet and warm is the slowest-drying combination there is.
