The two gentlemen from Mr. Duct who came out to provide me a quote were very professional and the quote to clean my dryer vent, which is approximately 40 feet long, and required the movement of a heavy front loading washer, was quite reasonable. After accepting the quote, these two young men not only brushed out the dryer vent, they also repaired the vent hose (which got dented when it was first installed), and vacuumed the floor behind the washer & dryer. Upon leaving, they also vacummed the throw rug in the foyer at the front door. Very thorough & professional. I'll be having this company back to do my vent cleaning.
