"This is my second review. Vince and his team did a fantastic job remediating the hidden mold in my basement as I reviewed before. Since then I have been worried about where else mold could by hiding in my home. Vince has gone above and beyond to help me feel comfortable again. Vince himself has made a number of trips to my home to check any suspicious areas each time that I contact him about. He has sent his team members too. I recently had my attic checked. I canâ t thank him enough for putting up with me. I have been extremely impressed with the whole home dehumidifier, Aprilaire, that his team set up in my basement. My basement humidity stays in the 40s or below. That is in all areas of my basement. Prior to the Aprilaire, I was using a single dehumidifier and it did a good job dehumidifying the area that the dehumidifier was set up in but what I didnâ t realize was that it wasnâ t dehumidifying the other areas of my basement. I have hygrometers set up everywhere now and I can see that the Aprilaire is doing its job. I do recommend Vince and his team. He does care for the well being of his clients!"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Mold Testing and Remediation FAQs, answered by experts

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.

Most mushrooms found on residential lawns are harmless. Certain varieties such as destroying angel, fly agaric, and vomiter mushrooms that can grow in grass will occasionally make their way onto residential lawn, but this is uncommon. Since mushrooms can be notoriously difficult to identify, if you suspect that your lawn mushrooms could be a poisonous type, consulting a professional is recommended.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

Mold loves a moist environment, so the best way to keep it from returning is to keep your machine as dry as possible. Take laundry out of the machine as soon as you can after a cycle finishes. If your laundry room is humid, consider using a dehumidifier or at least running a fan to increase airflow.

It's also a good idea to leave the washing machine door open when it's not in use, to improve airflow and keep the interior dry.

You can do a basic home water test, but we recommend having a pro conduct a more in-depth test. This method is accurate, and you’ll have a pro who knows your house helping you determine a plan of attack for anything out of the ordinary.
