"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

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

No, heated floors are unlikely to cause mold. In fact, they can help prevent mold growth. The additional heat helps dry excess water and reduce condensation, which can lessen the likelihood of mold growth. Additionally, the heated floors can help reduce humidity near the bottom of the floor.

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.
