If you're looking for a reliable, thorough and professional contractor-look no further! My dad is a retired contractor so I'm pretty picky. They were wonderful from start to finish; their quote for radon mitigation was lower than other bids I received, they communicated in advance and throughout the timeline, they were prompt and finished the project ahead of schedule. They made everything easy for me and put my mind at ease. They have my trust and I will definitely be using them for future home repairs.
The team from Drennen installed a radon mitigation system in our home this month and were knowledgeable and helpful in designing a system that worked for how we like to use our basement. It tested out great the first time. I would recommend them for other homes.
We recently had our front porch re-done by Drennen. The first carpenter did an excellent job of removing the old boards and stabilizing the under structure of the 20+ year old porch. However, he was less successful in doing the finish work. When we made these comments to Drennen, they agreed with us and came out within the week and redid the finish work. Now we have a lovely front porch that is a real asset to our home. The people at Drennen were easy to contact, came on time, were considerate, and cleaned up the site each day. They had earlier replaced our roof and did a nice and quick job. We are very happy with their company and already have another job scheduled with them.
The crew did a great job - really superior work. They arrived on time, worked quickly, cleaned up any mess, and kept me informed of what they were doing. I was impressed. The test they conducted for three days afterward showed a substantial decline in the radon readings - well below the 4.0 level in my case.
We have been devoted clients of Drennen for almost 30 years. The price, workmanship, interaction with the staff is all top notch. From little jobs to big, their work is professional and personal. They take the time to explain everything, and keep you posted along the way. They clearly love what they do and working with the community and each other.
As an established Realtor in Northern Colorado since 1994, I am constantly dealing with radon issues that can make or break deals. When my personal home tested high on radon, I knew immediately that I would be asking Drennan to do the job. I've worked with out of town companies that other Realtors injected into a transaction and was always dubious that they know what they were doing. Drennan arrived at our home with a TEAM of professionals that genuinely understand the science surrounding radon as well as the way various construction methods interact with it. I couldn't be happier with the process (including scheduling, billing, competency, and courtesy) and will insist my clients allow only Drennan in their homes for evaluation & mitigation work.
