"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."

"I would highly recommend Greg Hill. He’s a great guy and he knows what he’s doing. We appreciate all the work he did on our new church project. He took a 112 year old building and turned it into a modern day sanctuary, kids church and offices. We are totally loving it."

Mold Testing and Remediation FAQs, answered by experts

You probably have mold on your shower curtains because mold and mildew thrive and spread in warm, dark, wet, and unventilated spaces. Your shower is the perfect environment, especially the shower curtains, because they trap water in the folds and creases, plus they’re exposed to the most water spray. The best way to ensure mold stays off your shower curtains is to keep it dry so it doesn’t have a place to grow. Doing this can also help keep mold off your bathroom ceiling.

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.

Inhaling black mold spores, even from behind walls, can cause people to have a wide variety of potential health issues. Some people may only notice a few breathing problems, while others can become quite sick with symptoms related to severe allergies. Constant exposure to mold spores can lead to lung infections and other long-term health problems. If you believe you have black mold inside your walls, you will want to reach out to a pro for an inspection and for advice on how to take care of the problem before it causes severe illness.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.
