Although some have three or four panels, standard sliding glass doors (also called bypass or gliding doors) are typically two large panels of glass in frames made of aluminum, vinyl or wood and mounted on rollers. Usually one panel is fixed in place and the other slides back and forth. Older sliding glass doors used a single pane of glass in each panel, but today most are either double or triple pane. There may also be a large framed screen door that slides back and forth.

Typical costs:

  • Door prices vary far more than for most home improvement purchases, and consumers may be quoted significantly different prices for the same brand and model door from different retailers.
  • Prices start at about $300-$800 for a basic 5'-6' wide sliding glass door, or $700-$1,100 or more for a standard 8' wide door, typically with an aluminum or vinyl frame and options like a screen door or built-in blinds (between the panes of glass). With installation total cost can be $600-$2,000 or more, depending on local rates and the complexity of the project (ranging from replacing existing sliding doors of similar size and shape to creating a new opening in a solid wall). Some doors in this price range may be less energy efficient, drafty and only moderately durable, so look for units with energy efficient glass, factory-installed weather stripping and steel reinforcement, For example, Lowe's offers a 6' wide ThermaStar by Pella Vinyl Sliding Door[1] with clear glass and energy-efficient insulation for about $340, or with built-in blinds[2] for about $760.
  • Expect to pay $1,000-$4,000 or more for a 5'-8' sliding glass door that is pre-hung (the panels are already framed and everything is installed as a single unit, minimizing breezy cracks and holes). These can be made of vinyl, aluminum, wood, fiberglass or wood clad with a low-maintenance exterior like vinyl or aluminum, plus options like a screen door, triple-pane glass or a grid/overlay that creates the look of the multiple windows like a traditional French door. For example, the Andersen 400 Series Frenchwood Gliding Patio Doors[3] is available in an oak, maple or pine interior clad with a low-maintenance exterior, plus energy-efficient glass for $1,500-$3,800 or more depending on size, materials and options like upgraded door handles, a retractable or sliding screen door and upgraded exterior trim. With installation, pre-hung sliding doors can be $1,500-$5,000 or more.
  • Costs double for impact-resistant sliding glass doors designed to withstand hurricane-force winds. Mike Davidson Construction in Florida estimates that installing a 9' impact-resistant sliding glass door[4] costs about $3,700, compared to $1,800 for tempered glass.

What should be included:
  • A sliding glass door should be replaced in good weather; once the old door is removed the opening is exposed to the elements until the new door is in place. Two workers are typically needed to lift and balance the heavy glass panels. explains how to install a sliding glass door in an existing wall[5] . Ron Hazelton provides both written instructions[6] and a series of step-by-step videos for removing an old sliding glass door and installing a new one.
Additional costs:
  • Needed repairs to flooring, siding, deck or interior trim because of water damage, dry rot or other problems can add $50-$1,000 or more to the total cost, depending on the extent of the damage.
  • If not included, a sliding screen door can add $35-$150, or a retractable model can cost $100-$400.
  • Locks for additional security can cost $2-$600 or more, depending on style, design and materials, but average about $10-$50.
  • Before buying sliding doors with built-in blinds or shades, ask about how repairs are made and the cost of replacements. Many manufacturers have made it possible to replace built-in blinds, but replacements must be bought from the manufacturer.
Shopping for a sliding glass door:
  • A video by door manufacturer Gorell explains the options to consider[7] when choosing sliding patio doors.
  • Get several estimates. Sliding glass doors are available from local lumber yards; home improvement centers like Home Depot[8] or Lowe's[9] ; or search for a local door and window dealer through the American Window and Door Institute[10] .
  • Accurate installation estimates can only be done on-site, as measurements need to be precise and the condition of the existing frame and surrounding wall needs to be evaluated. If hiring an installer, verify that the company is properly insured, bonded and licensed[11] ; ask for and check references, and look for any complaints filed with the Better Business Bureau[12] .
