Sliding Glass Door Cost Factors

While we’re limiting this post to standard-size sliding glass doors, you still have many options that affect cost.

  • Material – Your options with specific pricing below are vinyl ($-$$), composite ($$-$$$), fiberglass ($$-$$$) and wood ($$$-$$$$) with and without exterior cladding.
  • Quality – Glass packages, hardware, how the joints are constructed and insulation quality are all available in basic, better and best grades for all materials.
  • Options – Sliding glass doors with grilles are 5% to 15% more expensive than comparable units without them. Those with adjustable blinds between glass panes cost up to 35% more in wood and up to 100% more in vinyl, partly because the option is available on premium models with the best overall quality.
  • Color/finish – Vinyl colors other than white increase the cost by up to 40% in the same patio door series. Finished wood and exterior vinyl or aluminum cladding on wood patio doors can increase cost by up to 50% over bare wood.
  • Energy Star Glass – Many high-end sliding patio doors include glass packages certified by Energy Star, just one of the reasons for the higher cost.
  • Who Installs the Door – DIY installation is cheapest, if the job is done properly. Handyman services charge affordable rates; The cost estimates from window and door contractors are the highest.

DIY or Hire a Pro?

I’ve replaced and installed many doors in the past. Replacing a sliding glass door is a fairly straightforward project for most skilled homeowners with the right tools. When vinyl or other types of siding are required to be repaired, it can be a bit trickier, but on most same size replacements, DIY installation is a good project.

  • Requires a truck or friend with a truck to get new door, as well as dispose of old.
  • Heavy lifting, so you’ll need a friend to help out.
  • Basic hand tools and a good level are really all you need to replace a sliding glass door.
