"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

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

The flooring that is the least toxic is solid wood. Natural linoleum, tile, stone, bamboo, and cork flooring also make the list of least-toxic flooring types. These flooring materials are safer and healthier for your home because they are natural materials that aren’t manufactured with chemicals, unlike laminate flooring. While some laminate flooring brands are made with less formaldehyde, many contain high levels of toxic chemicals that can off-gas in your home for months and years after installation.

Choosing natural flooring materials that are easy to clean without chemical cleansers can also help keep your home safer.

In most cases, it is safe to return home after mold remediation is complete. You should follow your mold remediation technician’s recommendations, but most pros request that homeowners wait one day after the process is complete to move back in.

After returning home, be sure to carefully inspect the exposed areas for any remaining signs of mold spores. Contact the mold remediation company if you detect any lingering mold.

You can kill slime mold with organic fungicides and commercial products like BioSafe Disease Control. However, the following substances will also get rid of slime mold: baking soda, potassium bicarbonate, cornmeal, cornmeal tea, and hydrogen peroxide. Typically, these fungi are cosmetic and rarely harmful to plants, so it’s OK to wait it out. The matter will disappear in a few days to two weeks.

Costs depend on property size, test types, and additional services like mold sampling.
