"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."

"Matt did an excellent job. He came to my house, assessed the basement, offered to arrange for a dumpster, and removed the damaged items left by the previous occupants. He provided two quotes, one including the dumpster fee and one without. A week later, he returned and worked quickly and efficiently. He was polite, professional, and hardworking throughout the process. Thanks to his efforts, my basement no longer has a moldy smell, and there’s no sign of mold, which was our biggest concern with winter approaching. I highly recommend his services."

"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."

"I cannot say enough about Abide Inc. They were professional, timely and knowledgeable and do fantastic work. I had them do a quote consultation and testing for a mold issue and asbestos abatement and they were prompt to make room in their schedule to fit us in and kept every word of their agreements throughout their Process. Chris Coopee did a fantastic job reviewing reports needed plus conducting a physical inspection of the property for mold in order to produce an informed accurate quote. He also is knowledgeable about asbestos abatement and conducted some testing at the site for us. Not only did Chris do a perfect job, but he turned around the ask in a tight timeframe due to our needs related to a real estate closing. Ann at the main Abide office fielded many questions from me throughout the week and was always pleasant and helpful. I highly recommend consulting this company for any remodeling or remediation needs. This is a great company with great people. Kudos to them!"

FAQs for indoor air quality testing projects in Leominster, MA

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
