"Corrie, the owner of Platinum Pest Control was great! We needed an escrow inspection done for our VA refinance and he took pride in taking care of us since he’s a veteran as well. The inspection was the last thing we needed for it to be finalized and he was prompt with getting us the report with a clearance right on the spot! Luckily we didn’t have any issues that needed to be fixed! His rates are low and he’s professional in what he does. Hire this guy!!"

Mold Testing and Remediation FAQs, answered by experts

Mold can grow anywhere in a home where moisture accumulates and doesn't dry out, particularly in areas with poor ventilation. Common materials affected include insulation and drywall. The most frequent locations for mold growth are attics, basements, crawl spaces, wall cavities, bathroom and kitchen walls, exposed foundations, windows and window sills, air conditioning and heating vents, and around fireplaces and chimneys.

If a professional mold inspector finds mold in your home, they’ll conduct mold testing to determine the type of mold species and the number of spores in your home. This plan will help develop a remediation plan, where a mold remediation specialist will remove the spores from your home. Since mold remediation costs the average homeowner $2,225, it’s best to treat mold at the first sign rather than waiting.

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

Yes, you can use bleach to remove mold from your aluminum siding, but it’s a powerful cleaning agent, so make sure it’s diluted with water first. A solution of one part bleach and four or five parts water works well. But it’s still a good idea to start by cleaning a small, inconspicuous area of the siding to make sure that the solution doesn’t cause damage or discoloration. 

Black mold often smells musty, stale, or earthy, and some people liken its scent to that of sweaty clothing. While not everyone can identify the smell of mold, you are likely to smell it before you see it, as it usually is hidden in dark, damp areas; instead, the scent may pervade your entire home. If you smell mold, start by opening windows and looking for the source of the smell. If you find mold or are concerned about side effects, call a mold specialist right away, as it can be almost impossible to get rid of yourself.
