"Rob Barish was very knowledgeable and informative. he was thorough and didn't try to rush through, he took his time to really do a good inspection and took the time to explain everything to me so I have better understanding at what I am looking at and looking for during the remodel. I would definitely recommend him to anyone in the NH area that needs a mold inspector."

"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

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

Yes, by identifying allergens and implementing measures to mitigate exposure.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.
