Under certain circumstances, a "retro-fit" installation of a new sliding glass door can be performed. This installation requires precise measurements of the exiting door frame. The sides and top of the existing frame stay in place and the bottom sill is removed. The new custom sized door is installed over the existing frame. It is set square, plumb and level and is sealed with high grade sealants to prevent water and air infiltration. A variety of trim options are available to complete the interior. This process is done with no stucco or drywall damage.
