"I was extremely impressed by Indoor Doctor! They are independent which means they do NOT offer remediation services and so they have no vested interest in any follow-up remediation work. Jeff, the owner, was very helpful during our initial call. They scheduled service promptly and James, who came to do the inspection, was professional and very educational about the possible sources of contamination. He was incredibly thorough and the final report had pictures as well as the laboratory findings. AND he followed up via text to make sure I had received the email report. It was less than 48 hours from the time he took the samples to when we had the very thorough report, most of which was favorable. They had concrete advice about next steps for the things that were causing air quality problems which we will implement. I cannot say enough positive things about Indoor Doctor!"

"Punctual, responsive, knowledgable, hard working problem solvers, and straight shooters in their evaluation of our system. Did not duct seal, not appropriate for our configuration. Had lower estimates but these folks were worth it to me; I’d use them again."

"If it would be possible I could give more than 5 stars. Jeff and Connie are very nice people and incredibly knowlegable specialists. They went above and beyond, conducting inspection of our house. I invited them because of presence of mold and odors. The house was thoroughly inspected not only for those problems we concerned of, but for all other possible hazards. Jeff and Connie spent as much time at our house as it was needed to complete all the aspects of required inspection. Each room, even every little space, furnace, AC unit, stove, refrigerator were inspected. Shortly after appointment I got detailed reports with photos and multiple very helpful recommendations. Now we know what exactly should be done in the house and outside in order to eliminate negative issues found by Jeff who is an expert in all aspects, related to different systems of house. Jeff and Connie are very kind and intelligent people. It was a real pleasure to spend several hours with them at our house. This appointment was life-changing for us. I highly recommend May Idoor Air Inspections to all who would like to make sure that environment of living places is safe."

"I explained to Jeff that I had bought a new condo, which was new construction, and I had concerns that the HVAC was not properly working and I wasn't getting enough clean air. Jeff was able to come the very next day. He is incredibly knowledgeable and clearly passionate about what he does. He conducted many tests - toxic gas levels, dust, mold, dander, etc. After about 30 minutes of testing, he identified I had a slow gas leak in my gas fireplace, which apparently had not been installed right. He stayed with me while the gas company came to remedy the situation. I am so grateful for him or I would never have known about the leak, which was probably contributing to health issues I was having. He also was able to turn around the other lab results incredibly quickly. Several others in my building have since hired him. Can't recommend him enough."

FAQs for mold & toxic material test projects in Salem, 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.
