Sliding Glass Door Replacement Cost

Various factors, such as the size of the door and your geographical location, affect the price of replacing a glass door. Usually, the cost to hire a professional fitter to complete the job (including tools, equipment, supplies and labor) ranges from $1,097 to $2,541, with an average of $1,659. Smaller jobs cost as little as $450, while bigger jobs cost as much as $4,000. Choosing expensive options, including fiberglass French doors and impact-resistant glass, significantly increases the replacement cost.

It's possible to reduce the cost of the project by doing the work yourself rather than employing a professional. In this situation, the main cost is purchasing the door, which is approximately $300 for a 6-foot door. Additional costs include renting or purchasing tools and taking time out of your schedule to complete the repair.

Sliding Glass Door Cost Factors

Sliding Glass Door Cost Factors

Many factors affect sliding glass door costs. When shopping for quotes, consider the following door price factors:

  • Size: While a basic 6-foot door is around $300, larger doors cost from $700 to $1,000.
  • Pre-Hung: A pre-hung door is a complete unit comprising the glass, door and surrounding frame. It costs approximately $1,000 to $4,000. Reusing your existing frame may reduce costs.
  • Frame Material: Common options include aluminum, vinyl and solid wood. A 6-foot painted aluminum door is approximately $1,350, while a solid wood door of the same size is up to $2,000. Vinyl sliding door costs range from $490 to $1,200.
  • Type of Glass: Many modern glass doors incorporate tempered glass. Upgrading to impact-resistant glass capable of withstanding hurricane-force winds doubles the cost.
  • Specialist Treatments: Stained glass installation, or adding doors with sidelights, substantially increases project costs.
  • Disposal: Professionals may charge $100 to $150 to dispose of the old doors safely.
  • Screen Doors: Adding screen doors increases your privacy but costs around $125.
  • Geographical Location: Costs vary by region. Your location may affect door costs relating to accessing the site, transportation and sourcing materials.

Sliding Glass Door Issues

Glass sliding doors require maintenance to stay in good working order. Additionally, aging or outdated doors may have issues that necessitate complete replacement. Potential issues include:

  • Leaks and drafts around the door frame
  • Cracked or broken glass
  • Rotting wooden frames
  • Poor sliding operation due to wear or debris in the rollers
  • Poor insulation
  • Poor security

Sliding Glass Door Repairs

In some cases, it may be possible to repair a glass sliding door rather than installing a new one. If the sliding mechanism is stiff, you can clean the door track or replace the rollers on the bottom of the door. If the door has started to leak or has become drafty, check for damaged weather stripping and replace it where necessary. If the glass breaks, it may be more cost effective to hire a pro to repair or replace the glass rather than replacing the whole door.

Regularly cleaning and painting sliding doors helps keep them in good working order after installation or remodeling a room. Spending a few minutes every week removing grime and preventing the onset of rot or rust can save money in the long term.

DIY Or Hire A Pro?

Although it's possible to reduce door installation costs by doing the work yourself, the installation involves handling large sheets of heavy glass, which poses serious risk of injury. Additionally, failing to install a door correctly could result in leaks, drafts or poor operation. Many homeowners prefer to hire a professional to replace exterior doors to ensure correct, safe installation.

How To Replace A Glass Sliding Door

If you're confident in your DIY skills, it's possible to reduce the cost of installing a door by doing it yourself and following these steps:

  1. Unscrew the inside head stop on the existing sliding panel
  2. Tip the top of the sliding panel inward, and then lift it out
  3. Remove the brackets securing the exiting stationary panel
  4. Lift out the stationary panel
  5. Remove the exterior trim and cut between the door frame and the opening
  6. Remove the complete frame from the opening
  7. Install a sill pan, if necessary
  8. Apply a thick bead of caulking along the sill
  9. Tip the frame into the opening, ensuring the frame sits in the caulk
  10. Check that the frame is plumb by measuring the diagonals to ensure they're equal
  11. Use shims to square the frame, if necessary
  12. Secure the frame with screws
  13. Insert the stationary panel and secure it in place with brackets
  14. Insert the sliding panel and secure it with the inside head stop
