The exhaust duct for the kitchen hood is at upper left in this photo. The darker drywall is water resistant, where the sink will be installed.
Ron and Cris from Ranserve installed the duct for the kitchen exhaust hood inside the kitchen, foaming all around the metal duct to insulate it and the exterior wall, then sealing up around the duct with drywall.
The exterior end of the exhaust duct. Ron and Cris will mount a screen to block bugs from traveling into the house through what is currently the open bottom of the duct.Catching up on other drywall details — the master bath, with water resistant drywall at the sink locations and the shelf that goes behind the vanity framed up.
