"Fantastic! It’s been about 2 weeks since we received our mold removal and treatment service from My Pure Environment. Our bathroom looks and feels great! We have a much easier time maintaining its cleanliness now that MPE has taken care of the mold issue. With 2 under 2 in our household, we are so happy to finally let them bathe in the tub without fear of mold toxicity! 10/10 would recommend and hire again!"

"Wow...I mean if you are looking for a mold specialist look no further...HIRE THEM!!! I received same day, extensive testing and help from a knowledgeable, extremely professional individual (Kerry). The testing was very thorough and we now feel confident that our home will be safe. We received excellent support and tips from him about what we can do in the interim as we await the testing results. We want to hire him when the results come back, as unfortunately we are anticipating some bad news regarding the mold in our home. However, we know that we are in good hands. We have 2 individuals that are immune compromised in the home and he is sending out the samples asap. I really cant say enough great things about this company. The proof is in the pudding so to speak. To have the response time and knowledge he has...just WOW!!! We can finally, for the first time in years, sleep at night without the worries of what will happen to us because we know he is the solution to our problems. This company comes out with a bunch of equipment and performs tests and takes samples. He means business when it comes to making sure your home is safe. If any loved one or friend of ours has a moisture or mold problem, I saved the number in my phone because he is getting recommended. THANK YOU SOOOO MUCH!!!! THANK YOU HOME ADVISOR AND MICROGARD!!! WE NOW HAVE A GUARD AGAINST THE MICRO INVADERS IN OUR HOME!!!!"

"Jeremiah was amazing with customer service. Attentive, always responded. Lamar was the technician. I just didn’t feel like he had a lot of experience but he was here quite awhile, inside and outside the home. Jeremiah said they charged $299 and no mileage fee, but did not mention that the two tests to see if it was black mold would be $700! That was upsetting but you were stuck because you had paid $300 for him to come out. It took a while to get tests back but that wasn't their fault. Just wish we hadn't been blindsided, but otherwise very reliable."

"On a whim I decided to check our radon levels in our basement. I guess I assumed this would have been done by the previous homeowner. Apparently one should never assume. My test game back at 5.9 pCi/L. The acceptable level is 4. And I wasn't going to chance my family's health. So I did my research on radon mitigation and sent a quote request through Angi's platform. I received a phone call the owner, John Spokis within 30 minutes on the Friday before New Year's. He explained the entire process and provided me transparent pricing over the phone and in writing via email same day. He was able to schedule us that Monday after New Year's. The installer Derek called me an hour before arrival to let me know he was on his way. He arrived on time, explained the work that was to be performed, reviewed the location with me and made sure I approved of everything before he started. The installation itself took about two hours. This included patching some cracks we had in our concrete at no additional charge. Frankly, I wasn't terribly excited about having a big white fan unit and pipe installed along my house. But I also knew that this was the optimal solution for our needs. And Derek took the time to make it look as neat and clean as possible. I really couldn't have asked for an easier or more pleasant installation at a very fair price. Oh and they guarantee after install that your radon will be 2pCi/L or below. They even give you a kit to test and make sure it has been lowered. There is a lifetime warranty on parts and labor that is transferable if you sell your home. And the fan has a 5 year warranty. So, if you have unsafe radon levels in your home. Don't procrastinate like I did. Just call Radon Systems and get it done in two hours. You'll be glad you did. I am."

"The company replied quickly with an initial quote. Of the three companies replying, Indoor Doctor was able to send a tech out the same day to perform inspections, testing and provide answers to my many questions. The tech was very professional, courteous, etc. Indoor Doctors provided an initial quote of $199 for the visit, which only covers the visit and inspection. They break down the separate fees for each test beyond the $199 inspection. There is a separate charge for each sample test. Mold test and allergen test from the same location are considered two tests and charged accordingly. Their pricing was competitive. Their ability to come out the same day was what sold us on Indoor Doctor. "

"I am very happy that I had All Clean Environmental Services to fulfill my project. They are extremely reliable in all aspects, price is reasonable. The terrific asbestos removal job was done, my place is left been very clean. The most important for me was a direct and clear communication with Kevin from the first phone conversation, during the project and after it was finished. He is a very knowledgeable specialist and the nicest person. Kevin went above and beyond making me been comfortable and absolutely worry free. Would like also mention that I appreciate how detailed were Kevin and Sorany with all documentation I was getting from them via emails. Thank you so much, Kevin and Sorany! Highly reccommend this company!"

"I called to get a quote on basement mold remediation. They arrived the same day I called, and 2 workers showed up on time to do a walk thorough of my basement. They did not try to sell me on services I did not need and in fact, gave me tips on how I could do the mold remediation as a DIY project. They were professional and honest ... values you do not see in many contractors these days. "

FAQs for mold & toxic material test projects in Sterling, MA

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
