Exceeded all expectations: Mr. Swett set up an appointment to evaluate the scope of work and was punctual, very professional, knowledgeable, and informative. He suggested a course of action; how the work would be done; explained the costs and charges; and answered all of my questions. Mr. Swett said that his crews were experienced and reliable and they delivered everything and more. When Mr. Leiva and his crew arrived (again, when expected and on-time), they were polite, clean, and began the work immediately. Mr. Leiva is EPA trained and tested; explained in detail what he and his crew were going to do; verified where I wanted the radon evacuation duct to be drilled in the slab, how the ducting would run, and where the duct would exit the house. All of the work done was impeccable, professional, neat with a high attention to detail, and their clean up left no trace of anything done (which included drilling a hole in the basement slab and the exit point for the discharge duct. Even the discharge duct that was run outside of the house was done in such a way that it is unobtrusive and blends in with the exterior of the house (the duct was run up next to a downspout that helps disguise the duct work). Mr. Swett also provides services to replace the radon exhaust fan in the event that there are any problems. I highly recommend Radon Abatement Services for any radon mitigation that needs to be done.
