The crew from Wise Vents came out on July 31 to clean the dryer exhaust vent in the wall in the condo I'm renting. I'm so glad they did! There was two years worth of lint and dirt accumulated which made my otherwise new and clean dryer not work right. After the Wise Ventz gentlemen worked their magic, the dryer worked great and had worked perfectly ever since! I'm more than satisfied with the service.
