"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

Neglecting mold growth on wood can result in various issues that deteriorate its appearance and jeopardize its structural stability. The mold's ability to multiply and expand can disintegrate the fibers of the wood, weakening it further. In addition, the allergenic spores and mycotoxins released by mold can pose health hazards through inhalation or contact. Ignoring the mold's presence allows it to thrive, increasing the likelihood of spreading to other surfaces and requiring extensive and expensive measures to control in the future. Addressing mold on wood promptly is crucial to preserving its condition and safeguarding the health of those around it.

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.

EIFS has several disadvantages, primarily related to cost and moisture. The system tends to have higher upfront installation costs compared to other siding options, and repairs can also be expensive, especially if water damage occurs. A significant downside is its low breathability, which can trap moisture between its layers from either leakage or condensation. This trapped moisture increases the risk of developing mold and rot, which can lead to costly and extensive repairs if not addressed promptly.

Mold can grow anywhere in a home where moisture accumulates and doesn't dry out, particularly in areas with poor ventilation. Common materials affected include insulation and drywall. The most frequent locations for mold growth are attics, basements, crawl spaces, wall cavities, bathroom and kitchen walls, exposed foundations, windows and window sills, air conditioning and heating vents, and around fireplaces and chimneys.
