He reviewed the test results with me prior to closing which gave me the peace of mind I needed to confirm I was making a good purchase and great investment. I highly recommend Mid Atlantic Commercial Residential Real Estate Solutions. VERY PROFESSIONAL AND COURTEOUS!!"

Mold Testing and Remediation FAQs, answered by experts

Since most mushrooms are beneficial for your grass, and otherwise harmless, it’s not a good idea to kill them with fungicide. If you suspect you have a poisonous type of mushroom in your grass, you should consult a professional concerning mitigation. There are lots of types of mushrooms and most are perfectly safe.

The best way to measure moisture levels in drywall is with a moisture meter. Moisture meters feature small probes that you insert into drywall (similar to pushing a pin into the wall). Ideally, you'll take moisture readings at several locations on the wall to get a general idea of the moisture level.

Mildew starts as a tiny spot, but if left untreated, it can severely damage your home as well as cause life-threatening health issues. Mildew eats away materials like wood and drywall and if left untreated can destroy entire walls and buildings. Mold sickness is almost a guarantee if you don’t tackle this problem as soon as it rears its head.

If the smell is closer to mildew or rotten eggs, the issue is probably mold or bacteria buildup in the machine or its drainage system. Clean your washing machine thoroughly, paying close attention to the rubber door gasket, as it can harbor odor-causing residue. Some machines have lint or debris filters that should also be checked and cleaned according to the user manual's instructions. Be sure to leave the machine's door or lid open after each use, as this allows for better air circulation and helps prevent mold growth.

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.
