"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

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.

Neglecting mold growth on wood can result in various issues that deteriorate its appearance and jeopardize its structural stability. The mold's ability to multiply and expand can disintegrate the fibers of the wood, weakening it further. In addition, the allergenic spores and mycotoxins released by mold can pose health hazards through inhalation or contact. Ignoring the mold's presence allows it to thrive, increasing the likelihood of spreading to other surfaces and requiring extensive and expensive measures to control in the future. Addressing mold on wood promptly is crucial to preserving its condition and safeguarding the health of those around it.

Yes, carpet mold can spread if not addressed properly or quickly. Mold can spread to underneath the carpet, impacting the subfloor or attached walls. Mold and mildew can spread within the first 72 hours, so it is important to address the problem quickly and remove any affected carpet. 

Mold can begin growing in as little as one to two days after your ceiling has been exposed to water. Mold grows and spreads quickly and can cause serious health problems. Always ensure areas with leaks are fully dried out, and any damaged material is replaced to discourage mold growth.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.
