Dave Lavalle and the Dryer Vent Wizard (DVW) Team did a terrific job on the installation of my new dryer vent. Their communication system is seamless, their technicians are professional, and their service is incredible. And since it was a new vent, DVW had to put it through my roof, which was a bit nerve-racking. Dave did a great job, and I have had no issues with leaks after several heavy storms. I would strongly recommend if you have any concerns/issue with your dryer duct, to call the folks at Dryer Vent Wizard. - Mark B.
