We used "Complete Dryer Vent Services,LLC. He is insured & CSIA Certified. Which means he is a Certified Chimney Sweep. Not that we have chimneys, But, he was the best person we used since we lived here the past 9 years. He was here for over an hour, pulled out the dryer blew it out from the bottom up & then went up to the roof & cleaned out the vent up there. He took pictures of all that he did & gave us the pictures. We both were amazed at the build up as we both are diligent in cleaning our dryer after each use. Which mean the other people didn't do a thorough job! The cost was well worth it @ $123. $23 was for the new hose. He also installs a new dryer exhaust hose that doesn't kink. #352-653-0809. We recommended him to our friends & everyone said WOW he was good
Ya get what pay for & this is a safety factor so you don't get build up in the vent/hose/roof vent. Next year it will only be $100.
