"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!"

"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."

"The installer was scheduled to arrive at 9 am. At 9 am I received a call that he would be about 15 minutes late because of an accident on his route. This was very much appreciated. When he arrived he quickly proceeded to select the proper location for the installation and inspect and seal any cracks in the basement flooring. He was very efficient and completed the installation in about two hours. After giving an explanation of the system operation and instruction on the retesting of the radon levels. He departed for another installation. The retesting was completed and the results were a reduction in radon levels from a 4.9 level to a 0.8 level. Not only does this system reduce radon levels it also helps to reduce dampness in the basement which will reduce molds. I would highly recommend Radon Systems if you need a mitigation system. The initial test is easy to do and I recommend that everyone should have it done a radon can be dangerous to your health."

"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. "

"Dave came by and tested for mold with this cheap test kit. He tested with my test kit even though he didn't think they were an accurate method. He proceed to do his own thorough assessment and did not see any signs of mold. When he concluded his visit without charging me anything! And that is so unusual these days! A+"

"They did a fantastic job. Very thorough, very professional, and provided before and after photos of the ductwork so you could see the night-and-day results. They also took apart every single floor register to clean them thoroughly, inside and out. Everything was spin-and-span clean when they were done and the whole house felt fresh. Very pleased with Aspen Air Duct Cleaning."

"Jeff is fantastic and extremely knowledgeable about indoor air quality. I was very nervous about spending so much money on an indoor air quality investigation, and due to the severity of the allergies I had developed, and the fact he came highly recommended by my allergist, I decided to hire him. He ended up being worth every penny. He spent 5 hours at our house, thoroughly taking samples from various places in the home (think it was 15 samples total), answering our questions, and providing recommendations on lots of things he observed as he went through the house (e.g. cleaning of the radiators, running a dehumidifier in our basement, etc.). Jeff called me the next day to report the key findings (he found several different kinds of mold spores coming out of the vent of the central a.c. system and low mold growth in the basement carpet). I then received a very detailed, thorough report of all his findings with lots of information and recommendations that was extremely helpful. It took us 8 months to figure out what to do with the 5 year old central a.c. system that had mold in the air handler and line up a contractor who would install exactly what we wanted for the new a.c. system (the previous homeowners had installed it in a location that made it extremely difficult to service and we couldn't even access it ourselves to visually see the mold Jeff had reported so we had to trust his test results and figure out a path forward). Over that time, we reached out to Jeff with lots of questions and he was responsive every time which was extremely helpful, it felt like we had a partner helping us to resolve the mold issues rather than "going it alone". The new a.c. installation was just completed last week and sure enough, when the existing air handler was removed from the house and opened up, there was mold in it (even though all the previous a.c. service guys told me they didn't see any mold in the unit). We are so grateful to Jeff for his help, knowledge, and patience in helping us create a healthier home!"

FAQs for mold & toxic material test projects in Nashua, NH

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.
