"Brian arrived with his worker, assessed the issues and presented a couple of options to work with. The work was done efficiently in a few hours and I no longer have any leaks in my basement. I was very impressed with the work and the way he goes about his business. There was only one area that we could not figure out if it was leaking from the foundation or if it was coming from above. We agreed to test it the next rain fall and have him come back to fix that section. Unfortunately it didn't rain again until spring and when it did I was unable to reach him. I think this company is no longer in business or at least that is the impression I get because all of his contact information is no longer in service. It's too bad because I really like the work he did for the price he quoted.

"The team was prompt in both arriving at the work site and performing the remediation. They were very helpful in explaining what was to be done and what needed to be done. I would use them for future mold remediation on any of my other properties."

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

"Lance and his wife did a tremendous job of fixing our radon problem. They were very well versed on what needed to be done. They were extremely deligent in getting their work done in a timely and safe manner. They stayed at my residence until they were sure that everything was done and done right. I would highly recommend them for anyone that needs a radon problem fixed."

"I hired the company to do a make ready [clean up & prep] on a single apartment in a building which I own in the  town where I live. I needed the property to be cleaned up so I could rent it again.  I have been a landlord for over 20 years & hadn't found a vacated property in such a mess in all my years. They did the complete interior clean-up which took about five hours. And, the complete prep of the property. they took out all the trash & junk, and cleaned up all debris left in the yard. They did such a great job with that I decided to use them for the yard maintenance also. They cleaned all my flowerbeds & got them ready for spring, placed mulch & trimmed the shrubs and flowering trees. On the inside they made everything look brand new! Cleaning the walls, painting, cleaned the carpets & stripped & polished the wood floors...making them look brand new. The appliances that stayed were cleaned inside & out. They even remembered to get all the light fixtures clean for me. Dusted all window seals & doorways. Shine mopped all they tile floors. To top it all off they even gave the bathrooms a fresh clean look by putting a new caulk seal around the tubs, sinks & shower...which gave the bathrooms a fresh face. All in all I found it to be a very stress free pleasant experience. And, I will definitely call on them for the next project because if they could do so well with a nightmare like that I'm sure the less difficult will be equally affordable and easily handled. Everything just looked so nice when they were finished. Thanks, Green Earth

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.

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.

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.

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.

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.
