Mold in a Huntsville house nearly always traces back to one of three things: a leak somebody hasn't found yet, water that sat too long after a pipe, appliance or storm problem, or the long humid stretch from late spring into September that keeps crawl spaces and attics damp. This site lays out what a proper cleanup looks like, when an inspection or lab sample is worth paying for, and how to size up a company before you let it start tearing out drywall. When you're ready, one call puts you in touch with an independent mold company that works in Madison, Limestone or Marshall County.

Mold needs moisture and something to eat, and every house has the second part covered: wood framing, paper-faced drywall, carpet backing, dust. So the whole question is water. Around Huntsville the weather supplies a lot of it. NOAA's 1991–2020 normals for Huntsville International Airport show about 54 inches of precipitation a year, and the average dew point stays above 60°F through every hour of June, July and August. Outside air that moist will condense on anything cooler than itself, which is why crawl spaces, air-conditioning ducts and the underside of subfloors are such common trouble spots here. Our humidity guide walks through the numbers month by month.
EPA's rule of thumb is a useful dividing line. If the moldy area is smaller than roughly 10 square feet (about a 3-by-3 patch) and the water problem is already fixed, many homeowners can clean it themselves with gloves, eye protection and an N95. Past that size, or after sewage, floodwater or a contaminated air system, EPA points people to professional remediation methods. Whatever the size, the moisture source has to be found and stopped, or the growth returns.
Less than most people expect. The Alabama Department of Public Health states there are no Alabama laws setting mold standards or testing requirements for homes or commercial buildings, and no state accreditation or certification for companies that test for or remove mold. EPA doesn't regulate mold in indoor air either. That means the burden of checking a company falls on you, and our hiring guide covers what to ask, including when Alabama's home builder license comes into play for the rebuild side of a job.
Requests come from Huntsville proper and Hampton Cove, Madison and Harvest on the west side, Meridianville to the north, Athens and the rest of Limestone County, and Guntersville and Arab down in Marshall County. Tell us your town when you call and we'll route you to a company that actually works there.
No. This site is a referral service. We pass your request to an independent local mold company, which inspects, quotes and does the work under its own name.
The Alabama Department of Public Health says there is no state accreditation or certification for mold testing or remediation contractors. If a job includes rebuilding and costs more than $10,000, the Alabama Home Builders Licensure Board says a state home builder license is required for that work.
EPA does not treat killing mold with bleach as a routine step, and Alabama Extension notes that bleach and other biocides leave behind allergens and irritants. The growth needs to be physically removed and the moisture fixed.
