"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

"Jon came by for a consult to look at some ugly looking black staining that was growing in my basement. He was very professional and punctual and thoroughly explained why it was not mold, but harmless mildew and how to rectify it. I was so appreciative for his integrity and honesty and I will absolutely use Indoor Environmental if I ever do get mold in my house."

"Fantastic service. Had high mold counts for my Dads house. Other companies were 2-3 times higher and we had to vacate the house for 5 days. Rey came in treated the house and we were back the next day. Had an independent mold tester come in after remediation and the results were well below acceptable levels. My Dads health has improved dramatically and has changed his quality of life: Thank you Rey!"

"My technician Tanner was extremely knowledgeable and friendly. After looking at my home and surveying for mold, I decided to have the air tested which he did right then and there. I am still waiting for the results but it was nice to know we had no mold issues."

"For those of you looking for an honest, kind, caring person in the world of “hazardous vapors” look no further than this company. Kevin at All Clean Environmental Services took my panicked call on a Saturday and listened in detail about health concerns regarding “moth ball odors” in my family’s rental property. With that he volunteered to come and “check out” the offensive odors. Kevin was very discreet as well as thorough in his handling of visit to “our” home. Having never dealt with this problem he was quickly in contact with his suppliers of treatment options."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Mold Testing and Remediation FAQs, answered by experts

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

Mold can damage the surface it’s growing on, cause mold-related sickness, and even affect your upper respiratory system.

Window sill mold can be harmful, but the severity depends on the type. Common household molds like Cladosporium or Aspergillus can trigger allergies, respiratory issues, or worsen asthma symptoms. However, black mold (Stachybotrys) can produce mycotoxins that can harm your health. Even less toxic molds should be addressed promptly to prevent health risks and property damage.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.
