"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."

"My husband and I began notcing cracks in our basement walls within the last few months so we contacted Frank to diagnose the problem. He was very knowledgeable and promptly told us what needed to be fixed. His crew began work within a week of us meeting, they worked quickly and efficiently and the job was done in 4 days. They knocked out 30 feet of our basement wall that had been damaged and the work was done in an extremely clean manner. They left the area meticulously clean. We also had 38 feet of wall on the other side of our house piered because it was settling. Frank lifted the house and piered the wall with a jacking system. We were extremely surprised as to how quickly all of the work was done and appreciated the professional manner in which it was completed. Frank even provided us a lifetime tansferable warranty. We highly recommend using Frank for any foundation repair work.

"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

Mold damage devalues a home in two ways: monetarily and emotionally. The numerical amount of mold damage devaluation can be 20% to 37%, which is substantial when house prices are often over $250,000. The second factor to consider is the emotional one: many buyers are hesitant to purchase a home that either has, or had, significant mold damage. For these reasons, it’s very important to deal with any mold issues immediately.

If you see black stuff under your vinyl flooring, it’s probably mold. There is a chance it could just be dirt, dried-out adhesive, or slight water damage, but some of those are causes for mold growth, so you should remove it immediately anyway. In some older homes, it could be black mastic asbestos. If you think it could be this–you guessed it–call a pro.

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

While it isn’t as dangerous as black mold, pink mold in the shower or elsewhere still poses some health risks, particularly for people with compromised immune systems. Even if you’re in good health, pink mold could cause an infection if it gets into your eyes or penetrates your skin through an open wound.
