Since a sliding door often leads to a patio or deck it gets a rigorous workout. If yours needs replacing, you'll be glad to know manufacturers have improved the design and construction of these doors. You'll find a good selection, in various sizes and configurations, at window replacement companies, home centers and lumberyards. And don’t go shopping for a slider with a closed mind, because you’ll find a large selection of styles, everything from French to Mission to Traditional designs, and you may decide to make the door the focal point of the room.

Timing-wise consider the weather, because once the old unit is removed the large opening is exposed to the elements. Also take the opportunity to consider if any repair work is needed to the siding, floor or deck or interior trim.

A contractor will charge $2,315, which includes labor and material, to replace an old 6-foot-wide two-panel sliding door with a new one. It will cost more depending on any needed repair work or additional carpentry. If you have extensive carpentry experience and tools, you can remove the old slider, buy the new door for $1,400, and make the installation, saving 40%. But this is not a trivial job, so if you have any doubts about tackling the job, hire a professional.
