"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

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Eliminating mold from wood permanently poses a challenge as the mold spores have the ability to deeply penetrate the porous wood surface. While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.
