"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

"Our 60+ year old well tank started to leak (original to house, used only for outside watering). Eric came to price out the replacement of the tank. Because we have an existing bleeder system, the newer tanks with bladders were not a fit. Eric took extra time to assess our situation to make sure we got the right tank kind and size for our needs. We very much appreciate the extra time he took to "get it right" and to explain things to us. He was later able to return, replace our tank and remove our very old and large tank. We value his attention to detail and patience, and we appreciate that as this is his business, he takes pride in his reputation. We would definitely recommend his company to others."

Veteran owned indoor air quality testing, engineering and consulting firm. Some risks are unavoidable but Indoor Air Pollution is a risk you can do something about. IndoorDoctor engineers test for possible environmental hazards, such as poor air quality. We define your environmental concern, evaluate its significance, and develop corrective actions or preventative plans to reduce the perceived hazard. Our reports are totally unbiased as we are not in the remediation business. For example, we have helped our clients to identify air quality issues that are contributory to ill-health such as molds and allergens. Many of our customers request air quality assessment before investing hundreds of thousands of dollars in a real estate purchase. Other customers use our reports to support insurance claims. But all of our customers want the peace of mind that knowing the air they are breathing is free of environmental contaminates.
"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."

"The inspection was a farce. We received a list of very minor repairs that needed to be done along with a couple of recommendations for system replacement due to age in the future. The inspector did not go up on the roof. If he had, he would have seen how soft the roof was. My wife notice the porch roof leaking during our remodeling project as the insulation was wet. Our contractor walked the entire roof and said it was an emergency to replace it. Sure enough 1500 sq feet of plywood of a 2000 sq foot roof had to be replaced. It was soft, splintering and wet. The splintering and disintegration should have also been visible from the attic hatchway. I am out $12,500 because of his negligence or laziness, I am not sure which. Do NOT use this company under any circumstances."
