How Much Is a Sliding Glass Door?

Installing a sliding glass door costs an average of $2,639, with prices ranging from around $1,050 for a single-glazed door to over $7,000 for a large, wood-framed door with double glazing, tinting, or other features, like shades or pet panels. Most projects will cost $1,169 and $4,265 for the cost of the materials and labor.

Sliding Glass Door Prices

Sliding glass door prices depend on the size and type of the door, as well as the door frame material and additional features, like blinds or shades or inserted pet doors for dogs and cats to easily roam inside and out.

Size

Sliding glass doors range from $400 for a smaller, 4-foot-wide door or around $2,500 for a 16-foot-wide door. The price tends to range from around $10 to $50 per square foot for the door and materials.

Type

Specialty sliding glass doors cost $1,000 to $6,500. A smaller, automatic door starts at around $1,000. You’ll pay the most for double glazing or a six-panel design that spans up to 16 feet.

Materials

The door material can impact the cost, with wood and fiberglass being more expensive than materials like vinyl or composite.

Features

Added features, like smart locks, pet panels, grids, or retractable screens, can add $20 to $500 each to the final project cost.

• Grids: An aesthetic addition to sliding glass doors, grids are usually included in the cost of the door you choose and increase the cost by about $50–$100.

• Pet panels: Adding a pet door into the sliding glass door costs $150–$400 and makes it easier for pets to let themselves outside and back into the house.

• Blinds or shades: Basic blinds or shades for sliding glass doors cost $20–$150, while built-in blinds can add $150–$400 to the cost.

• Locks: If you want extra security, plan to pay $20–$100 more for an after-market lock or up to $700 for a smart lock.

• Screens: Installing a screen costs $150–$500. Retractable screens, which run from $100–$400, are stored in a side channel of the door when not in use.

• Insulation: Improved insulation inserts for sliding glass doors cost $300–$500, but can help reduce monthly utility bills.

Sliding Glass Door Installation Cost Factors

Door installation costs depend on the size and type of door as well as if you are replacing an existing door or inserting a sliding glass door into a wall without an existing opening.

Cut Wall for Door

Creating a new opening for a sliding glass door and adding framing costs $700 to $2,100, not including the cost of the new door.

Remove Old Door

Removing an old door before installing a new exterior door costs $100 to $250. Replacing an existing sliding glass door is typically less expensive than the cost to insert a new sliding glass door into a wall without an old door or other existing opening.

Size

Larger doors are more expensive to install, costing around $3,500 for a 16-foot door without any extra features compared to a smaller, 4-foot door that starts at around $400.

Type of Door

The type of door ranges from $400 for a two-panel door to over $6,500 for a six-panel door, and the type of glass can also impact the cost.

• Low-E: This glass, which costs $100 to $500, boosts the energy efficiency of the door and helps block UV light.

• Textured: Textured glass, which starts at around $500, helps improve privacy.

• Impact-resistant: For glass that can withstand strong winds or hits from debris or playful and curious kids, the cost is $300–$500.

• Soundproof: You can minimize the sounds of neighbors’ lawn mowers or local traffic with soundproof glass for an additional $1,200–$4,000.

• Tempered: This type of glass costs around $1,000. Tempered glass is durable, like impact-resistant glass, but also snaps into larger pieces if broken.

• Gas-filled: Gas-filled glass is designed for improved insulation and costs around $500.

DIY vs. Hiring Door Installers

The cost of labor to install a sliding glass door is about $70 to $100 per hour or $300 to $800 total. Large doors over 8 feet wide may cost $100 per linear foot. The process will take about 2 to 7 hours for two skilled professionals to install.

Given their size and weight, these doors aren’t usually a DIY job. A single panel weighs about 40 to 60 pounds, and you’ll need at least two people to do the work. A pro can ensure that it’s done properly, usually within a few hours. When you’re ready to search for sliding door installers near you, be sure to read reviews and get at least three quotes before you select a pro.

Benefits of Window Tinting

Adding window tinting costs around $5 to $30 per square foot, but it can offer many benefits. Tinted sliding glass doors can improve privacy or even security. One of the biggest benefits is the added UV protection and heat absorption, making your interiors feel cooler even on the hottest, full-sun days. Plus, deflecting the harsh light can prevent the natural light from fading your furnishings or rugs.

FAQs

How do you maintain a sliding glass door?

One of the most common ways to maintain a sliding glass door is to vacuum the sliding track regularly to prevent the doors from sticking. You may also need to apply lubricant to the door wheels or track to prevent squeaking.

How long does it take to install a sliding glass door?

A professional door installer can install or replace a sliding glass door within a few hours, although large doors may take up to 7 hours.
