Drennen Custom Contracting

Aug 2023

They installed our radon system 12 years ago. We were very pleased with the installation back then and with the performance of the system since then. Vacuum dropped to zero recently and they came out to replace the fan. Again, very impressed with their honesty, professionalism, quality of work, and reasonable pricing. Highly recommended.

We received excellent service from Drennen when we recently sold our home and needed radon mitigation. They were prompt, professional, reasonably priced and pleasant throughout the job. Their work completely addressed the problem.Service: Fan installation

Drennan Custom Contracting was the only one of 5 radon mitigation companies that provided me with an estimate. We agreed on a date and time for the work in my crawl space; they were prompt; professional; friendly; took some unusual circumstances right in stride; completed the work on time; everything in the system is in compliance with State and Federal regulations and recommendations; my radon levels went down to the safe level they predicted; and their price is at market-price level. ALL of that is pretty unusual in contractors these days. I would recommend this company to anyone looking for ANY work Drennen does, not just the radon mitigation. They are awesome!!
