The Radon Specialist Team did a great job and finished in one day installing a mitigation system. Abe, the owner, even stopped by before they got started to ensure everything was good and their plan was sound. The installers were professional and knowledgeable. Everything was explained in detail and workmanship was top notch. They even cleaned after install to a high standard. It was $2500 dollars for a system installed even with our complex situation of a slab and crawl space combo.
