"We had had a new kitchen put in and then a year later, we had had our kitchen floor redone and basement repaired after a flood in our house. Water from our washer had flooded the kitchen and laundry room and then flowed through the floor into the basement theater room and rec room. We had to have a new (porcelain) tile floor put in upstairs and new paint and carpeting throughout the basement. The work for the new kitchen and then the flood required a huge amount of sanding, spackling and more sanding...etc. The dust in our house was a big problem afterwards from the spackle dust that accumulated in our ducts. We decided to have our ducts cleaned and found All States on Angie's list. It went great! They were on time, conversant about the state of our ducts. They did the job. I have noticed that the air is better in the house and we have much less dust on furniture! Very happy with their services and I would definitely hire them again.
