We are property managers and needed the (extremely dirty) grout lines in a house cleaned. My account rep is Kathy and my technician was Justin and I will definitely use them again! After another company came and was unable to make much of a difference, I was googling for a solution and found COIT. Kathy called me back about what was needed. She came out to measure and price and offer solutions - even adjusting it later to accommodate our reconsiderations. Justin worked extremely hard on a Sunday and tried lots of things to find the very best solution for us. Now the house sparkles and we are COIT customers forever! Thanks for great service.
