"I called Summit Environmental Services, Inc, (after I had worked with another company that I had received a referral from through Home Advisor). I spoke with Jeff, the owner of Summit and told him the problems that I was having. He called someone who was already out working in the field. Jordan came to our house that afternoon and took the needed samples. Stated that he would get the results of the samples early the next week. He also spoke to another person referred by them for mold remediation. That person spoke with us and stated that as soon as he got the results, he would do what was necessary to remove the mold. I am so grateful for this company. They saved me time and stress that another company had caused. If I could give them a 10 rating, I definitely would."

"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

Checking for mold yourself is crucial, as catching mold in the early stages is ideal. Mold can appear green, brown, black, blue, or yellow. It can smell musty and can feel like velvet, leather, or cotton. 

Most often, mold grows near water damage. It’s best to inspect these places for signs of mold growth:

  • Basement: Look in corners, windows, carpet, closets, and around appliances. 

  • Bathrooms: Check around sinks, ceilings, and around toilets. 

  • Kitchen: Inspect around the sink, behind the refrigerator, and behind trash can.

  • Attic: Look near the insulation and near intake and exhaust vents.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.

Mold can grow quickly in wet carpet: in as little as 12 to 24 hours. That’s why it is crucial to take action immediately if there’s any sign of water damage under your floor. Remove as much water as possible with a shop vac and towels, then use baking soda to help remove moisture deep in the fibers. Always steam clean the carpet or use an antibacterial carpet sanitizer to kill any mold growth.

Most mushrooms found on residential lawns are harmless. Certain varieties such as destroying angel, fly agaric, and vomiter mushrooms that can grow in grass will occasionally make their way onto residential lawn, but this is uncommon. Since mushrooms can be notoriously difficult to identify, if you suspect that your lawn mushrooms could be a poisonous type, consulting a professional is recommended.
