"Helped me with questions about air quality in my home and specific causes and treatments when tests proved I had issues. As a result, I am well on my way toward a cleaner, safer environment. I am a Vietnam era vet and the technician (not giving his name without his awareness) upon realizing that showed tremendous respect."

"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."

I have 13 years of combined construction and inspection experience. I will provide you with great service, a thorough inspection, and a detailed report with pictures and explanations. I will not leave until you are satisfied. There is no need to call multiple inspectors and waste your time making multiple trips to the property, as our inspector also can perform testing for Radon, Mold, Asbestos, Lead, and Allergens.

Mold Testing and Remediation questions, 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.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

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.

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Yes, a refrigerant leak is extremely toxic and dangerous to breathe. Refrigerants can displace oxygen in a room, which can lead to suffocation, loss of consciousness, serious health issues, and even death. You may also suffer from refrigerant poisoning, which can cause symptoms like headaches, nausea, dizziness, swelling of the throat or sinuses, vision loss, and a burning sensation in your eyes, ears, nose, lips, and tongue. If you experience any of these symptoms, you should seek medical attention immediately. In addition, refrigerant leaks are toxic to the environment and can cause permanent damage to the ozone layer.
