Major Cost Factors of Sliding Patio Door Installation

Door size, frame materials, brand, and glass type have the biggest impact on cost.

Door Size

Larger doors naturally cost more. Most sliding patio doors are 80 inches tall, though it’s possible to purchase oversize doors with heights of 82 or 96 inches. These doors are usually 60, 72, or 96 inches wide. Three-panel sliding doors that cover an entire wall can be even wider.

Standard-size sliding glass doors cost about $10 to $50 per square foot. Just as custom windows cost more than standard windows, custom sliding glass doors cost more.

Door Frame Material

Sliding patio doors come in several frame materials, each with their own benefits and price ranges.

Glass Types

The type of glass in the door also affects the price. Untreated, single-pane glass panels cost the least, but they can pose safety, security, and energy-efficiency problems. Specialty glass shatters less easily and helps prevent heat from transferring indoors. Terms like “impact-resistant,” “hurricane-proof,” and “laminated” are sometimes used interchangeably but do have some differences, so always make sure you know what you’re buying.

Type of GlassCost Range


Top window brands, such as Milgard and Pella, sell sliding glass patio doors. These companies offer sliding doors at a variety of price points, but brands such as Marvin and Renewal by Andersen typically have more high-end options.

Other Factors Affecting Sliding Door Installation Cost

Depending on the specifics of your door project, the following considerations may also come into play.

Number of Panels

Most sliding glass doors consist of two panels, but larger walls can allow for three-panel and even four-panel doors. These are a larger financial investment but can create a striking look and allow for greater continuity between your home’s interior and exterior space. Here’s how material costs break down by panel number.

Old Door Removal

If you’re replacing a patio door with a new one, expect to pay $100 to $150 to remove and dispose of the old door.

Retrofitting vs. Creating New Opening

It’s easier and less expensive to install a sliding glass door in an existing door opening than to cut an entirely new opening. Cutting the opening alone typically costs between $400 and $1,500, and contractors will also need to install a frame for about $300 to $600. Since this project requires structural alterations to your home, you’ll need a permit for a new door opening and may want to hire a structural engineer. This can cost anywhere from $300 to $1,500.

Professional vs. DIY Sliding Patio Door Installation

Most homeowners should opt for professional installation for this type of door. Here’s why.

Professional Sliding Door Installation

Anytime your project involves cutting into your home’s walls, you should hire a professional contractor. This includes putting in a set of sliding glass doors, even if you’re enlarging an existing door opening. Compromising your home’s structural integrity isn’t worth trying to save money on labor. Additionally, sliding glass doors are heavy—typically between 40 and 60 pounds—so this job usually requires at least two people. The best door and window installation companies will help protect your home and ensure your new doors are installed properly and securely.

DIY Sliding Door Installation

Experienced do-it-yourselfers (DIYers) may be able to handle sliding door replacement for one or more panels, though it will probably require at least two people. You’ll need to pry the old frame out of the jamb, apply new flashing, install a sill pan, fit the new frame in the opening, and insert the glass panel. Then, you must finish the interior and exterior door frames with insulation, trim, and caulk. Doing this incorrectly can create air leaks and potentially even security problems. If you have any doubt about your abilities, hire a professional.

Sliding Patio Doors vs. Other Door Types

Sliding glass isn’t your only patio door option. Here are some other popular choices.

Costs of Different Types of Doors

Here’s how these door styles compare in price.

Type of DoorCost Range
Screen doors$150–$600
French doors$900–$5,800
Folding glass doors$4,600–$13,800

Additional Options to Consider During Sliding Door Installation

If you’re installing sliding patio doors as part of a larger home upgrade, consider the following extra projects. Many times, you can save on labor and minimize construction time by bundling projects.

Install a Patio or Deck

If you want your home’s outdoor space to get more use, consider installing or upgrading a patio or a deck. Patios typically bookend the rear of your home and start with a poured concrete or paved floor. They’re a less expensive option priced between $2,000 and $5,700. Decks, which are raised wooden structures that may be attached to the house or freestanding, cost slightly more at $4,100 to $11,900. Both options can be customized with simple features such as a fire pit and chairs or an entire outdoor kitchen.

Repair or Replace Flooring

Particularly if you’re cutting a new opening for your sliding glass doors, you’ll want to make sure your flooring can withstand the extra foot traffic. Flooring prices are calculated by square foot and vary widely by material. Vinyl and linoleum flooring are usually the least expensive and can cost as low as $1 per square foot. Carpet can range from $3 to $22 per square foot, and high-quality tile and hardwood can easily cost $30 per square foot. Patio flooring can cost anywhere from $1 to $4 per square foot for gravel and up to $35 per square foot for granite flagstones.

Upgrades and Add-Ons

You can add several extra features to your sliding patio doors to make them more functional or attractive. Here are some of the most common options.

Window Replacement

The Department of Energy estimates that 25% to 30% of home heat loss occurs through windows, particularly single-pane windows. Since most sliding glass doors are sold by window companies, it may be a good time to get a new set of windows to match your new door. You may be able to save on labor by installing both at once, and measuring for new windows is easy to do yourself.

Energy-efficient windows transfer less heat and keep out drafts, meaning your HVAC system doesn’t have to work as hard to keep your home comfortable. The typical window replacement cost is $670 to $1,390 per window, but you’ll save on utility bills long-term by upgrading your home’s energy efficiency.

Our Recommendation

Sliding patio doors are an excellent way to join your home’s indoor and outdoor spaces. Even when closed, they look attractive and allow in plenty of natural light. We recommend insulated sliding door frames and treated low-e glass to keep your home as energy-efficient as possible. Look for a set of doors with a good warranty, and opt for professional installation for the best results.
