How Much Does It Cost to Install Sliding Glass Doors? [2025 Data]

Sliding glass door costs range from $1,170 to $4,267, but most homeowners pay an average of $2,642. The size and type of door have the biggest impact on what you’ll pay, with standard sliding door sizes costing $10 to $50 per square foot. You’ll also need to consider labor and materials, especially if you hire a sliding glass door installation pro.

Sliding glass doors are a versatile, functional, and energy-saving way to let light into your home. Here’s what you can expect to pay based on all the factors involved in buying and installing sliding glass doors.

Sliding Glass Door Installation Cost Factors

The cost to install a sliding glass door depends on several factors, including the size, type, material, number of panels, type of glass, and local labor rates.

Door Size

Doors come in standard sizes, and sliding doors are no exception. Two- or three-panel sliding glass doors fall between 60 and 144 inches wide and 80 and 96 inches tall. Expect to pay $10 to $50 per square foot for the most common sliding door sizes. Smaller options start at $400 on average, and larger ones can cost as much as $3,500 for everything involved.

Larger sliding glass door installations require more material and labor to install and are, therefore, more expensive. Here's how to break down the cost of sliding glass doors by size.

Type of Door

Sliding glass doors come in a handful of different styles at a range of costs. Here are some of the most common specialty options and what they cost on average.

• Automatic doors: Automatic sliding glass doors open and close at the touch of the button—and you’ll pay handsomely for the convenience. Expect to pay between $1,000 and $3,500 for an automatic option.

• Hurricane-proof doors: Hurricane-proof doors are designed to withstand the brute force of a hurricane (and the debris that gets blown around). Door options in this category cost between $2,000 and $3,000 on average. A layer of tempered glass protects against breaking during impact; these doors may be required by local building codes in hurricane-prone areas.

• Double-pane doors: Dual-pane sliding glass doors provide additional insulation and thus are more expensive than their standard, single-pane counterparts. Budget between $2,500 and $3,500 for these doors.

• Multi-panel doors: The larger and more expensive a sliding glass door is, the more panels it has. Options with two panels or up to six range from $2,500 to $6,500. Special features, such as bi-fold or telescoping doors, may be included at the higher end of the cost range.

Door Materials

Doorframe material costs vary, with options like vinyl costing the least and fiberglass costing the most. Here’s what you can expect to pay depending on your chosen material.

Keep in mind that the doorframe is just one component of sliding door materials. When budgeting, also consider the other parts of your sliding glass door, including the glass panes, latches, and tracks. 

Number of Panels

The vast majority of sliding glass doors feature two- or three-panels. Our cost ranges primarily encompass these popular designs. However, you'll occasionally encounter four-panel sliding glass doors as well. Here's what you can expect to pay for each.

Glass Type

The type of glass you select will impact the cost of the project, with Low-E coming in at the most affordable option.

Labor

Professional sliding door installers charge between $70 and $100 per hour or roughly $300 to $800 for entire projects, and that’s on top of what you’re already paying for materials. Going the DIY route can reduce or eliminate these costs, though keep in mind that you’ll have to set aside some of your budget for all the necessary tools for installation. 

Additional Costs to Consider 

Beyond the door itself and the labor to install it, a few other factors must be taken into account when estimating the final cost.

Installing a Screen

If you want to have the option to open the sliding door while keeping the screen closed, it can add between $100 and $500 to your project costs. While this can increase your budget, consider the benefits of the fresh air it will allow into your home. 

Replacement Parts

If you already have a sliding glass door that isn’t working properly, you may need to invest in some replacement parts. These can include rollers, tracks, glass, and the sliding panel. If the door isn’t sliding smoothly, you can ask your contractor to see if they can find the correct tracks and rollers and replace them. This costs between $110 and $300 on average.

Depending on the type and size of the sliding door glass replacement, it costs between $100 and $1,000 or more. 

Old Door Disposal

When you replace an existing sliding glass door, your contractor can remove and dispose of the old one for $100 to $250. This part of the job is often included in the overall quote, but check with your pro if you’re unsure. 

New vs. Replacement Door

Replacing a sliding glass door will naturally cost less than starting from scratch since the rough opening and frame are—in theory—already in place. The cost to replace a patio door averages $2,500, though replacing just the sliding door glass costs $250 to $1,000. On the other hand, installing a new sliding door in a bare wall will add between $1,000 and $3,600 to your total, adding up to over $6,000 altogether. 

Partial vs. Full Replacement 

Homeowners looking to save on sliding glass door installation can opt for partial replacement in some scenarios. Partial replacement involves removing and replacing just the glass or hardware rather than the entire door.

Glass replacement costs an average of $250 to $1,000, saving you hundreds or even thousands. However, a full sliding glass door replacement may be more practical for more extensive remodeling projects.

Brand

There are many trusted sliding glass door brands on the market, and your window installation team can help you pick the right one for your budget and design. Each brand offers a range of customization options, materials, and styles. Some brands offer specialized Low-E glass for insulation, while others incorporate automatic smart features. 

Cost of Common Sliding Door Add-Ons

Here are some other features you can add to your sliding door for an additional cost:

• Grids: This stylish feature can be added to most sliding glass doors and costs an average of $50 to $100. 

• Pet Panels: If you need an easy way for your cat or dog to get in and out, installing a pet panel on your sliding glass door might be worthwhile. The cost of pet door installation adds anywhere from $150 to $1,500 to your overall budget.

• Window Treatments: Blinds or shades built directly into a sliding glass door range from $150 to $400. Window treatments that are sold and attached separately cost between $20 and $150. 

• Locks: Adding a lock to your sliding door can cost anywhere from $20 to $700, depending on the type of lock. Advanced, remote-controlled, and smart locks are on the higher end of the cost range. 

• Screens: Screens for sliding glass doors add anywhere from $150 to $500 to your final bill. 

• Window Tinting: Window tinting can provide additional privacy, protection from UV rays, and prevent sun stains on your furniture. You’ll pay between $5 and $30 per square foot to add this feature to your sliding glass doors. 

Cost to Install Sliding Glass Doors Yourself

On average, professionals charge between $300 and $800 for the labor involved in installing a sliding glass door. You don’t need to worry about labor costs if you’re doing this project yourself, but you will need to either rent or buy all the necessary tools to do the job. Even with all of that factored in, you can expect to spend between $700 and $2,500 to DIY.

DIY vs. Hiring a Pro 

Although it can be less expensive to install sliding glass doors yourself, this job requires a lot of work, tools, and heavy lifting. It may cost a bit more to hire a professional sliding door installer in your area, but they have the right tools and skills to do the project quickly and safely. There are, however, plenty of sliding door repairs you can tackle on your own, such as cleaning the track or replacing the hardware. 

Ways to Save Money on Sliding Glass Doors

When you’ve exhausted your budget and need to find a way to cut back, use these tricks to make your sliding glass door installation less expensive. 

• Avoid new construction: Cutting a new doorway dramatically increases the cost to install a new sliding door. If possible, replace an old sliding door, rather than installing a sliding door in a new place where a door didn’t previously exist; this will reduce or eliminate new construction costs entirely.

• Install the sliding glass door yourself: If you have the skills and tools (or can rent or borrow them), you’ll save between $300 and $800 by DIYing your sliding glass door installation. However, make sure you’re ready to tackle a project of this size; incorrect installation can lead to energy loss, water damage, and even home security issues.

• Spend more on certain add-ons to save in the long run: This may sound counterintuitive, but one of the best ways to save money when installing sliding glass doors is to spend a little extra on add-ons. Add-ons such as window tinting, insulation inserts, and certain types of glass may cost more up front, but they’ll help you cut down on energy costs over time. For example, you won’t need to run the heat or AC as often if you can rest assured that your sliding glass doors aren’t letting air escape.
