"...They were prompt, on time and were the consummate professionals. They put the system in under adverse time constraint conditions and by putting in an additional system as well to bring the radon to acceptable 1.6 levels. Their dogged determination to get the job right with pride was commendable to us. Their work was clean, neat and orderly. They cleaned up after themselves so we hardly [knew] they have been there. They are an example of true professionalism in an age of complacency!"
