Abbey Environmental Testing and Services, Inc.
We offer residential mold inspections, air quality testing for molds and allergens, and radon measurements. We're BBB Accredited and for the past three years have been awarded the BBB Certificate of Customer Satisfaction and Excellence! Our mold inspections evaluate both external and internal conditions of your property and identify when there is mold.

In the event of a small mold contamination, we can remediate to return the area to a pre-mold healthy condition. For larger remediations, we can refer you to a number of excellent remediation companies that we work with. Our radon measurements use state of the art CRM's (Continuous Radon Monitor) that provide important data on radon levels within the environment.

We're fully insured, certified and licensed and we educate our clients while we go about our business!

IndoorDoctor LLC
IndoorDoctor LLC
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."
