"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

Water damage doesn’t always cause mold and wood rot, but it can. Both mold and wood rot require moisture in the wood to form, so water damage that continues to leave water or moisture behind can lead to both issues. Water damage and mold often go hand-in-hand, but you can prevent mold growth after water damage by addressing the source of moisture and drying out the area quickly. The same goes for wood rot. The longer you let water damage go, the higher the risk of mold and rot.

The difference between mold and mildew is that mildew is a mild type of mold, whereas mold can be used to describe many different types of fungus. In general, mold is more dangerous than mildew. If you spot mold in your home, you will need a professional mold remediation specialist to help clean and remove it.

Mold in a basement is harmful as it can trigger allergy symptoms, especially for those with asthma and other breathing conditions. Symptoms of mold exposure include itching, sneezing, running nose, and congestion.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
