On the exterior we remove the siding on the front of the garage and installed new hardboard siding that matched the original on the building. Electrically we removed and relocated existing lights and added a ceiling fan as well as recessed lighting. Some additional outlets and network wiring was installed then connected to the home and panel box. The interior was insulated in areas such as the ceiling, stairwell and miscellaneous sections of the walls. We laminated (overlay) the existing sheetrock with 3/8″ wallboard on the sidewalls and stairwell and 1/2″ for the ceiling.
For those searching for more room when you decide to remodel two spaces come quickly to mind. These are your garage and your attic. Both have benefits and drawbacks as far as conversion to a bedroom or usable space goes. It is a bit more easily converted than your attic and can result in a beautiful living space. Before you begin work you should know the real garage remodeling costs involved. Converting your garage to a bedroom requires certain elements that are not necessary for a family room. When converting your garage to a bedroom you will need to have a window that serves as a secondary escape route, and a closet. There are additional requirements by code, but these are the main ones to consider.
Paint manufacturers have recognized these problems and have come to the rescue with new solutions. But a word of advice: If your garage floor sees heavy water leakage, if it's badly cracked or if it's damp and slimy all summer, don't apply any coating. In those cases, you're better off simply keeping it as clean as you can and then calling it quits.
