Soleil is the Arlington homeowners 125-pound Newfoundland dog and she used to have her own door to go outside before the renovation. Homeowners Emily and Nick decided to install one in the mudroom wall, but it can’t go in the ideal place (under the window) because that’s where the outdoor stairs are located. Using the dog’s shoulder height measurement, Tom Silva has started a rough opening by cutting out some studs in the wall and building a new header. The header sits on a stud on the right and a new jack stud on the left to make sure it can carry the load above. Then Tom puts the insulation back in and fills the void with expanding foam before putting in one more jack up against it. He cuts the rough opening through to the exterior—first the two sides and then the header. Kevin O’Connor makes the final bottom cut from the outside, which is pitched two inches lower so that any water will run away from the house. After the drywall is back in place, they install the door kit—with saloon style door panels—and Soleil gives it a test.
