Almost an immediate response after requesting a quote on Home Advisor, Service Professional responded the very next day, and was in fact early for the appointment. I hired him after the quote and the work was completed the same day. In addition to replacing faulty Washer Hot and Cold Shut-Off Valves, the Service Professional also vented the dryer properly through an existing, but unused roof vent, supplying the necessary venting materials. The repair was a bit costly, but it comes with a two year guarantee. I am extremely satisfied with the work, and will certainly hire them for any future projects.
