A sliding glass door is a perfect way to access a backyard, patio, or deck. The large glass panels let lots of light inside and offer a scenic view outside. Over time, a sliding glass door will wear down from lots of use or it could become damaged and require replacement.
The cost to replace a sliding glass door ranges from $1,000 to $7,500 with the average cost to replace a sliding glass door at $2,510. Sliding glass door replacement cost depends on the size and type of door being installed and the door installation cost. There are many different materials, brands, and customizations to choose from when homeowners are purchasing a new sliding glass door. Each selection is detailed in this cost guide along with tips on how homeowners can hire the right professional to replace their sliding glass door.
Key Cost Factors
The cost to replace a sliding glass door depends on several factors. The most significant factors revolve around the door itself—the size, type, and material. Homeowners will also want to consider the labor cost to replace a sliding glass door and other factors detailed below.
Door Size
Door size is a leading factor in the cost of sliding glass doors—the larger the door, the larger the cost. A small 4-foot-wide sliding glass door can cost as little as $400, while large sliding glass doors cost much more; for example, 16-foot-wide door can cost up to $3,500. On average, glass sliding doors cost $10 to $50 per square foot, with the average cost of each standard size as follows:
| Door Size | Cost Range |
| 4 feet | $400 to $1,400 |
| 6 feet | $600 to $1,500 |
| 8 feet | $700 to $1,600 |
| 10 feet | $950 to $1,900 |
| 12 feet | $950 to $2,000 |
| 14 feet | $950 to $2,500 |
| 16 feet | $1,300 to $3,500 |
Door and Glass Type
In addition to a basic sliding glass door, there are a few different types available with added features. These features include enhanced durability, weather resistance, insulation, and enhanced functionality. Specialty glass sliding doors cost anywhere from $1,000 to $6,500, depending on the feature. Some examples are listed in the table below.
| Type of Sliding Glass Door | Cost |
| Automatic | $1,000 to $3,500 |
| Hurricane-proof | $2,000 to $3,000 |
| Soundproof | $2,000 to $3,500 |
Door Material
Sliding glass door frames can be made from several different materials, each one at a different price point. Vinyl and composite tend to be the least expensive materials at $300 to $1,200 and $600 to $1,200, respectively. Composite is slightly more durable than vinyl but usually not as high-quality as wood, aluminum, or fiberglass. Aluminum sliding glass doors cost between $750 and $2,500 and typically withstand high winds and heavy rain, while wood sliding glass doors cost between $1,000 and $3,000 and are typically chosen for their aesthetic value. Fiberglass sliding glass doors cost $1,500 to $2,500 and are extremely durable and low maintenance.
Number of Panes
There can be anywhere from one to three panes or layers of glass in a sliding glass door. Single-pane glass will cost anywhere from $350 to $1,500, double-pane $450 to $2,100, and triple-pane $2,000 to $3,000. While the cost to replace a double-pane sliding glass door and triple-pane is higher than for a single-pane door, the more panes of glass a door has, the more durable it will be and the better it will insulate. Those who live in areas with extreme weather or extremely high and low temperatures should opt for two- or three-pane glass sliding doors, as they are more energy-efficient and will reduce energy costs.
Brand
When homeowners are purchasing a new glass sliding door, there are several brands to choose from. Each one will offer a different price range, level of quality, warranty coverage, and more. Popular glass sliding door brands include Andersen, Marvin, Pella, Jeld-Wen, and Milgard. The average cost for each brand is listed in the following table.
| Door Brand | Cost Range |
| Anderson | $800 to $3,500 |
| Jeld-Wen | $750 to $3,500 |
| Marvin | $2,800 to $3,900 |
| Milgard | $1,000 to $3,500 |
| Pella | $350 to $2,400 |
Labor
The cost to install a sliding glass door ranges from $300 to $800 in total. This equates to about $70 to $100 per hour, and the entire process will take anywhere from 2 to 7 hours. The exact time required will depend on the difficulty of the project. For example, the cost to replace a sliding glass door with a hinged door, the cost to replace a sliding glass door with a solid wall, and the cost to replace a window with a sliding glass door will all be more expensive than the cost of a standard glass door replacement due to the complexity of the task. Each of these projects will require two skilled professionals. Pricing can also be determined by the length of the door. Installing a sliding glass door over 8 feet long will likely cost about $100 per linear foot.

Additional Costs and Considerations
In addition to the aforementioned sliding glass door replacement costs, there are a few more that could help narrow down the cost of certain projects. Homeowners will want to consider whether any of the following may affect the new sliding glass door cost.
Customizations
There are certain customizations that can be added to a glass sliding door that will increase the overall replacement cost. Some of the most common customizations are listed in the table below.
| Customization | Cost Range |
| Adding a pet door | $150 to $400 |
| Adding a smart lock | Up to $700 |
| Adding grids to the glass | $50 to $100 |
| Additional insulation | $300 to $500 |
| Installing basic blinds or shades | $20 to $150 |
| Installing built-in blinds or shades | $150 to $400 |
| Upgrading the door lock | $20 to $100 |
These customizations can improve the look of the doors, increase sliding glass door security, and even help homeowners lower their monthly utility costs, but homeowners will need to weigh the costs against the benefits to decide what makes the most sense for their needs and their budget.
Disposal
If a homeowner is swapping out an existing sliding glass door with a new one, the old one will need to be removed and disposed of. Homeowners can expect to pay $100 to $250 to have the old door removed. This cost will likely already be included in the total cost proposal provided by a contractor, but it is important for homeowners to understand how much this part of the project may cost. The contractor will take the old door to a scrap yard, where it could be repurposed depending on the condition.
Glass Replacement
If just the glass in a sliding glass door needs to be replaced, homeowners will have several types of glass to choose from, each at a different price point. The cost to replace glass in sliding glass doors depending on the type is as follows.
| Type of Glass | Cost Range |
| Gas-filled | $500 and up |
| Impact-resistance | $300 to $500 |
| Low-e | $100 to $500 |
| Tempered | $1,000 and up |
| Textured | $500 and up |
- Gas-filled: Gas-filled glass has superior insulating properties and is a good option for glass sliding doors in very cold and very hot climates.
- Impact-resistant: Impact-resistant glass or hurricane-resistant glass can withstand heavy wind, rain, and impacts from flying debris.
- Low-e: Low-e stands for “low emissivity.” A thin coating on the glass blocks out ultraviolet light and prevents energy loss.
- Tempered: Tempered glass is almost indestructible, meaning it will likely not break. If it does break, it will break into large sections rather than dangerous slivers of glass.
- Textured: Textured glass adds a stylistic element to a sliding door and can be frosted, fluted, beveled, rippled, glazed, etc. It can be useful to obscure the view into a home, providing privacy.
Sliding Panel Replacement
The cost to replace a single panel in a sliding glass door ranges from $400 to $700. If the sliding glass door is in good shape and just a single panel gets damaged, whether from extreme weather or reckless use, it is possible to just replace the panel and keep all of the original door framing. The new panel will likely need to be from the same manufacturer and be the same size as the existing one in order for the replacement to work properly.

Rollers and Tracks Replacement
After many years of extensive use, the rollers or tracks that guide a sliding glass door open and closed could become damaged and need to be replaced. The cost to replace rollers on a sliding glass door ranges from $110 to $300. This type of repair is not always possible, as the contractor will need to find rollers or tracks that are compatible with the existing door panels. If the contractor is not able to do so, the homeowner will need to replace the door entirely if the track stops working properly.
Screen Installation
Installing a sliding screen door along with a sliding glass door allows the homeowner to keep the door open on nice days and let fresh air inside while keeping bugs outside. A standard sliding screen on a sliding door will cost $150 to $500, while a retractable screen will cost $100 to $400. A retractable screen retracts into a housing chamber so that it can be hidden out of the way when not in use.
Sliding Glass Door vs. French Door
A sliding glass door and French doors operate differently. Sliding glass doors slide open with at least one panel permanently fixed and at least one panel that slides. French doors swing open with two doors that swing either inward or outward. The cost to replace sliding glass doors with French doors ranges from $1,000 to $4,000, depending on the size difference between the existing door and the new French doors. With their classic feel, French doors are often chosen over sliding glass doors for the aesthetic value as they offer.
Types of Sliding Glass Doors
The cost to replace sliding glass patio doors depends on the type of material chosen. There are several materials used for sliding glass doors. Vinyl and composite tend to cost the least, wood and fiberglass tend to cost the most, and there are a few other options that fall in the middle of the cost range.
| Type of Door | Cost Range |
| Aluminum | $750 to $2,500 |
| Composite | $600 to $1,200 |
| Fiberglass | $1,500 to $2,500 |
| Metal | $500 to $1,000 |
| Vinyl | $300 to $1,200 |
| Wood | $1,000 to $3,000 |
Aluminum
A new aluminum glass sliding door falls in the middle of the cost range; homeowners can expect to pay $750 to $2,500 for one. Aluminum doors are very durable and, therefore, ideal for homes that experience heavy wind or rain. The material will resist water, but it does tend to produce more condensation due to the thermal conductivity. Aluminum sliding glass doors are often black, white, or gray.
Composite
Composite glass sliding doors, which cost between $600 and $1,200, are made of a synthetic material that combines many common door materials into one. Composite doors are usually of higher quality and longer lasting than vinyl; they are available in a wide range of colors or can take on a similar look to a wood or metal door.
Fiberglass
For a new fiberglass sliding glass door, homeowners can expect to pay $1,500 to $2,500. While they can be costly, fiberglass sliding doors are typically well worth the price. They are durable, low maintenance, and will last for many years; however, they can sometimes crack over time. Fiberglass doors can be customized to any look or color.
Metal
The cost of a new metal sliding glass door ranges from $500 to $1,000. Typically either steel or aluminum, they are budget-friendly and tend to be a little more durable than vinyl. Similar to frames on vinyl sliding doors, the frame on metal sliding doors can warp or bend in certain warm weather conditions or from rough use. A metal glass sliding door is a good option for modern and contemporary homes.
Vinyl
Vinyl sliding glass doors tend to be the most popular due to the entry-level price point; installing one will cost between $300 and $1,200. Vinyl doors come in a few different colors, including white, ivory, taupe, and black, or they can mimic the look of wood or metal. The material is durable for the most part, but it does have a tendency to warp in hot temperatures, as it is a bit more malleable. Vinyl glass sliding doors are low maintenance and resistant to water damage but typically will not last as long as fiberglass or wood doors.
Wood
Wood sliding glass doors cost between $1,000 and $3,000, making them one of the most expensive options for a patio door. Most homeowners who choose a wood sliding glass door do so for the aesthetic; they either have wood windows across the rest of their home or like the natural look of the wood framing. Wood sliding doors offer excellent insulation; however, they do require more maintenance than vinyl or metal. These doors will need to be refinished after a while and should be protected from water.
