Got an appointment soon after calling company. Russell Hill arrived on time and efficiently set up the radon monitoring device. He was professional and explained procedures. He returned in three days to retrieve the device. Written report received soon after. This process proceeded very smoothly.

Calling Hill Environmental was one of the best decisions I've ever made as a homeowner. I was facing a relatively small but unusual mold issue. In addition to the independent testing and remediation planning that I was expecting (which were excellent), Russell continued to provide information and insights throughout the remediation process. I had several decision points as that work progressed, and being able to rely on his perspective at each step provided invaluable peace of mind and probably saved me a ton of money. Looking back, I'm confident that my mold issue is fully resolved without any extraneous work. Also, thanks to Russell, I'm now much more knowledgeable on the topic and better positioned to prevent future issues.

Such a positive experience from start to finish. I have worked with my share of air quality, radon, asbestos abatement and similar environmental professionals. Russ’s calm, helpful, knowledgeable, patient, accommodating and expert approach put me at ease from the start. We are renovating an old bathroom and I was worried about health risks during the demo. Russ efficiently isolated the mostly likely concerns and tested for those concerns. He emailed the results to me exactly when he said he would. When I had follow up questions about precautionary measures we should take, he calmly and confidently walked me through the options and gave me a roadmap. Russ clearly knows his craft and you will feel confident and safe for having hired him. Five stars - will absolutely hire again.

I was able to schedule an appointment with Russell quickly after a contractor’s actions left our family worried that we may have asbestos contamination. He helped us develop a cost-effective plan for testing and was very informative, polite, and professional. I certainly appreciated the swiftness of his service and responses, and I would definitely use this company again for future testing needs.

I am taking the time to write this review the day of service, I was that impressed with Russell and Hill Environmental Solutions. He was very patient with my questions, professional and knowledgeable. He also worked very well with the other asbestos contractors that were there, treated them with respect and courtesy, and the two companies worked great together. I feel very confident now that my home is safe for my two year-old and the air quality healthy and I attribute a large part of that to my experience with Russell Hill. I highly recommend his company. (That's Russell in the white suit:)).
Response from the owner · 7 years ago
Thanks Sean for the wonderful review! It was a pleasure working with you and the contractors on-site this afternoon. I'm pleased our services are allowing you and your neighbors piece of mind regarding the air quality. Great picture by the way! Have a great Christmas!
