"Mold test took air samples inside and out after we discovered some questionable spots that worried us. Samples are sent to a lab for analysis. We subsequently purchased a mold remediation kit from another firm and treated the house. We are breathing easier now. Thanks!"

"This is not a mold remediation company. When you hire this company, you are simply getting a mold test. Be specific when you explain your problem and what you are looking to get done. The mold technician was in and out in 20 minutes. He took an air sample and one swab, that s it. For the price of $299. Once you get the results of your mold test, they refer you to a company that is in the business of selling mold remediation products. Originally as much as $1600 for mold bombs, sprays and commercial graded air scrubber. I negotiated down to $1195. Then settled on only what I needed. Know what you want, do your homework before buying products you do not need."

"Upon submitting the request for quotes on mold remediation I was contacted by Dave within hours to 1 day. I had a consultation scheduled with Dave within the week. I can not attest to the testing services of All Mold & Basement Services as I had the testing done prior to submitting the quote requests. Dave was very professional and forward with his process. While their process is very similar to others on this site, they go the extra mile and use a dry ice blasting technique to remove and eradicate the mold from all services and even between the joists and flooring which other companies could not guarantee would be done. Because of this process they weren't the lowest quoted price but the end result was the wood looked BRAND NEW. Both my wife and I were astonished. There were some delays in getting started and finished however this was not due to the company but adverse weather. With close to 1,600 sqft needing work and in meeting the agreed upon deadlines some areas appeared to had been missed and were brought up with Dave. He personnaly came out with one member of his crew and the necessary treatment materials and immediately took care of the questionable spots. I can't speak highly enough of Dave and his folks and I would highly recommend this company if you have need of mold remediation work."

"Prompt response time via text (especially compared to local competitors). Very easy to work with. Very generous with his time and knowledge. Gave me very balanced, realistic advice for future property improvements (especially compared to the advice of local real estate agents). Online payment system and reporting were at current industry standards and not outdated."

Mold Testing and Remediation FAQs, answered by experts

Frequently, fungi have a gray color with a powdery or fuzzy texture on a wall. In showers, fungi and mildew may resemble a pink slime. Meanwhile, toxic mold may resemble a fuzzy growth on walls that’s often black or green in color. Some toxic black mold will have specks of orange or white on it. However, not all dark-colored mold you find on a wall is toxic. An infestation of toxic mold often will spread faster than fungi on walls. If you are unsure whether you have toxic mold, reach out to a professional for help.

Telling the difference between poisonous and nonpoisonous mushrooms is difficult even for trained mushroom experts and biologists! However, nature provides some red flags for poisonous mushrooms. Assume that any mushroom with a red cap or stem is poisonous. You should also assume mushrooms with white gills, rings, skirts, or a sack-like base are poisonous. 

Costs depend on property size, test types, and additional services like mold sampling.

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.
