How to Attach a Garage

Attach a Garage to Your House

• 1

  Select the place in the house where you want to put a doorway that will lead to the garage. Make sure this lines up with the place in the garage where a doorway can be cut. However, the house doorway is most important to settle on first, as there is less wiring, plumbing and other materials you have to worry about when cutting a hole in a garage structure. Make sure there are no important electrical or plumbing lines you will be cutting though in your home or if there are, how you will have to reroute them.

  Clear the outside area between the garage and the house. Pour a cement foundation that you will build the passage-way frame on. Ensure the ground below the cement is level and smooth. This will most likely be the case since a house and a garage are built on either side of it.

  Construct a passage way between the house and the garage with a frame of 2x4's, pieces of sheetrock and insulation. Use a table saw to cut the 2x4 pieces to the proper length and the pieces of sheetrock to fit within the wooden hallway frame. Use a drill and heavy-duty screws to attach these pieces of 2x4 into a frame and pieces of sheetrock between the boards. Use screws to attach insulation between the frame and the sheetrock as well, if you think this is necessary.

  If the passageway between the garage and the house is long enough, add roofing and siding materials to the outside of the passageway you have now constructed to protect it against weathering and leakage. Aluminum siding and inexpensive roofing shingles will work, though you may want to use the exact same materials you have already had installed on the outside of your home and garage so that it matches.

  Cut door frames in the house and in the garage wall on opposite sides of the passage way. These door frames should be sized for doors you have already selected to be installed in the passage. Depending on the distance between the garage and the house, only one door may be necessary.
