How Much Does a Sliding Patio Door Cost?
A sliding glass patio door can cost anywhere from $600–$10,000, with your design preferences impacting what you pay. For example, buying a standard-size door, which typically measures 72-inches-by-80-inches, made of aluminum will put you closer to an average of $2,756 for materials and labor. Doors that fall outside standard sizes, especially those made of premium wood or fiberglass with multiple glass panes, can cost several thousand dollars.
Budgeting Tip
- If you’re on a tight budget, it’s important to decide which sliding glass door features to prioritize so you can save money while also investing in a home upgrade that meets your needs.

What Factors Affect the Cost of Sliding Patio Doors?
A few different factors can impact the cost of installing a sliding patio door, including the type, glass, materials, and size. You’ll typically pay more for a more complex door than a simple model. So if you want a bifolding door, a telescoping door, a set of French doors, or any other unique sliding patio door design, expect higher project costs. Learn more in the sections below.
Door Type
When talking about the type of door, we’re describing the number of side-by-side vertical panels a door has. Patio doors come in a variety of types, ranging from simple two-panel doors to folding glass doors adorned with iron. The variety of styles available is why the price range for sliding patio doors is so wide.
Most homeowners install two-panel patio doors but those with large spaces may choose as many as six-panel patio doors. As you can see in the table below, the more panels you choose, the more you’ll pay.
| Door Type | Cost Range | Average Cost |
|---|---|---|
| Two-panel door | $400–$1,500 | $950 |
| Three-panel door | $1,500–$3,500 | $2,500 |
| Four-panel door | $2,500–$5,500 | $4,000 |
| Five-panel door | $3,000–$6,000 | $4,500 |
| Six-panel door | $3,500–$6,500 | $5,000 |
Door Glass
You can find patio doors with various types of window glass, ranging from decorative to impact-resistant. Some options enhance energy efficiency, while others provide protection or simply improve the door’s appearance. The more security and energy efficiency the glass provides, the more it will cost. Below is an overview of average costs for different types of glass for your door.
| Glass Type | Cost Range | Average Cost |
|---|---|---|
| Low-emissivity (low-e) | $100–$500 | $300 |
| Impact-resistant | $300–$500 | $400 |
| Gas-filled | $400–$600 | $500 |
| Textured | $500–$1,000 | $750 |
| Tempered | $700–$1,000 | $850 |
| Hurricane | $1,000–$3,000 | $2,000 |
| Soundproof | $1,200–$4,000 | $2,600 |
Glass Panes
As with windows, you should have the option of choosing single-pane, double-pane, or triple-pane glass for your sliding door. This describes the layers of glass panes a door has. Single-pane doors are the cheapest option but come with the least insulation. Today’s standard is double-pane glass since it provides a balance between energy performance and affordability. But if you live in a cold climate, you may want to invest in triple-pane glass to keep cold air out.
Glass Treatments
In addition to the glass itself, you can typically select from various glass treatments.
- Low-emissivity glass (low-e): Glass with a low-e coating is an energy-efficient option. This coating prevents the sun’s heat and ultraviolet (UV) rays from coming through the window into your home without blocking natural light.
- Impact-resistant glass: In storm-prone areas, impact-resistant glass offers protection against winds and other storm elements. It can also provide peace of mind to homeowners worried about break-ins.
- Gas-filled glass: If you choose multipane glass, you can add a nontoxic gas between the panes for added insulation. While it may cost more, this type of glass is beneficial if you live in a particularly hot or cold climate and want to keep drafts out.
- Textured glass: Textured glass offers a unique look and enhanced privacy. You can choose to have the glass frosted, beveled, glazed, or rippled.
- Tempered glass: This type of glass, also known as safety glass, is designed to break into smaller, more manageable chunks when damaged rather than large, sharp shards. This can offer value in regions prone to storms.
- Hurricane glass: Hurricane-proof glass can resist extreme weather conditions and flying debris. You likely don’t need to spend the extra money on this upgrade unless you live in a hurricane zone.
- Soundproof glass: If you live in an area with high noise pollution and want to minimize disturbances, consider installing soundproof glass.
Pro Tip
- As demonstrated on an episode of This Old House, when standard annealed glass breaks, it shatters into large, sharp, dangerous shards. Tempered safety glass, by contrast, explodes into thousands of tiny pieces that are far less likely to cause serious injury.
Door Material
Sliding glass patio doors come in various materials, with some more budget-friendly than others. Below, we’ll cover the most common materials for sliding glass doors with average costs.
| Material | Cost Range | Average Cost |
|---|---|---|
| Vinyl | $300–$700 | $500 |
| Aluminum | $600–$1,000 | $800 |
| Composite | $600–$1,200 | $900 |
| Wood | $500–$1,500 | $1,000 |
| Fiberglass | $1,500–$2,500 | $1,500 |
| Steel | $2,000–$4,000 | $3,000 |
Knowing more about each type of door material can help you choose the best option for your home.
- Vinyl: Vinyl is one of the most popular patio door materials because of its affordability and low maintenance. However, it doesn’t seal as tightly as more energy-efficient options.
- Aluminum: Aluminum patio doors are heavy-duty and hold up well, but they’re not very energy-efficient and are prone to condensation buildup.
- Composite: Composite patio doors are long-lasting and moderately priced, but lack significant curb appeal.
- Wood: A wooden frame material looks nice and insulates well, but is prone to warping and rotting in moist climates.
- Fiberglass: Fiberglass is one of the more expensive options because of its exceptional durability, customization options, and energy efficiency. However, it often reacts negatively to certain cleaning products.
- Steel: Steel is typically the priciest patio door material. It’s highly durable and versatile, but dents easily. Steel is also prone to rusting.
Pro Tip
- The material you choose for your sliding glass door can significantly affect your final price. This Old House Magazine notes that vinyl helps cut costs while minimizing maintenance. Aluminum-clad wood costs considerably more but reduces maintenance while echoing interior wood trim. Aluminum is strong enough to have narrower stiles and rails, offering a sleeker look at a premium price point.
Door Size
Most patio doors measure 80 inches tall, or approximately 6 1/2 feet, with availability in a range of widths. A wider door will use more materials, hardware, and glass panels, which means you’ll pay more. The table below shows the costs of sliding patio doors based on size.
| Door Size | Cost Range | Average Cost |
|---|---|---|
| 48 by 80 inches | $400–$800 | $600 |
| 60 by 80 inches | $400–$800 | $600 |
| 72 by 80 inches | $600–$900 | $750 |
| 84 by 80 inches | $700–$1,000 | $850 |
| 96 by 80 inches | $700–$1,000 | $850 |
| 108 by 80 inches | $800–$1,000 | $900 |
| 120 by 80 inches | $950–$1,200 | $1,075 |
| 144 by 80 inches | $950–$1,300 | $1,125 |
| 168 by 80 inches | $950–$1,300 | $1,125 |
| 180 by 80 inches | $1,300–$1,600 | $1,450 |
| 192 by 80 inches | $1,300–$1,600 | $1,450 |
Can You Install a Sliding Patio Door Yourself?
Though you can install a sliding patio door yourself, the job requires more than basic home improvement skills. While do-it-yourself (DIY) installation could save you money, the job will likely take longer than if completed by a professional—and if you do the work incorrectly, you could end up paying more money to fix issues in the long run.
DIY Sliding Patio Door Installation
While installing a sliding patio door yourself can save you on installation costs, you may need to buy new tools or extra hardware that reduces these savings. Homeowners may also take longer than professionals to complete the job, and the door’s warranty won’t cover any mistakes. We don’t recommend the DIY route unless you feel completely comfortable with this type of work and have the right tools to ensure safety and proper installation.
“The benefit of a professional is they have the skills to install a door quickly, safely, and correctly,” says Kinyon. “[A professional] will complete a typical job in a couple of hours, compared to a DIY project that takes multiple days if the homeowner isn’t familiar with the installation process.”
Professional Sliding Patio Door Installation
We recommend hiring a professional if you don’t have the experience or tools to install a sliding patio door yourself. A professional can make your door fits into its existing frame, as standard sizes may not always accommodate your unique space.
Professionals also have the necessary equipment to complete the job properly, like leakproof flashing, shims, and polyvinyl chloride (PVC) cement. Plus, professional contractors have the required strength and skill to lift patio doors, which can weigh up to 100 pounds or more. Expect the project to take several hours, including the removal of your old door.

Should You Repair or Replace Your Sliding Patio Door?
Homeowners with damaged sliding patio doors must decide whether to replace or repair their sliding door. Repairs often cost less than replacing the entire frame, but you may need a full replacement if the damage prevents your door from being sufficiently secure or energy-efficient. Keep in mind that if you choose to replace your door, you must remove the old one first.
According to Kinyon, most reputable patio door installation companies typically include removal and disposal fees of the old door as part of their overall estimate. “There are factors that could raise this [cost], such as the size of the door or additional hardware to remove, which should be reflected in the original number given,” he adds.
Is the Cost of a Sliding Patio Door Worth It?
In many cases, installing a sliding patio door is worth the cost for the added value of natural light, improved outside visibility, and its kid- and pet-friendly features. The exact cost of a sliding glass door depends on the door’s material, size, type, features, and brand. Professional installation increases your labor costs but ensures a lasting result.
We recommend investing in Energy Star-rated doors to help keep your electric bill from rising unnecessarily. Consider whether you want to invest in other features, like storm protection. To keep your total cost as low as possible, only invest in features that provide the safety and energy performance you need. Avoid features that only affect appearance to stay within your budget.
FAQs About Installing Sliding Patio Doors
How much does a standard-size sliding door cost?
Installing a sliding patio door can cost anywhere from $600–$10,000 on average, depending on the door’s size, material, glass type, and brand. Vinyl and aluminum frames tend to fall on the lower end of the range, while wood or fiberglass options cost more. Additional features, like energy-efficient glass or built-in blinds, can also increase the price. Labor and installation costs may increase the total project cost by an extra $400–$1,400 or more.
Do sliding glass doors add to your home’s value?
Yes, sliding glass doors can increase your home’s value by improving natural light, enhancing indoor-outdoor flow, and boosting curb appeal. Buyers often appreciate the added functionality and modern look these doors provide, especially in living areas that open onto patios or decks. Energy-efficient models can also reduce heating and cooling costs, which adds long-term value.
Are sliding patio doors expensive?
Sliding patio doors are often expensive. It may not seem like it, but patio doors require a significant amount of materials to construct. They also come with energy-saving features, like low-e glass coatings and gas insulation, that prevent air leakage and heat transfer, helping to keep your energy bill from increasing.
Can you replace a patio door without replacing the frame?
Yes, you can get a new sliding patio door without replacing the door frame if both the existing door and the frame are in good condition. Most homeowners choose to replace their frames only if they’re old or damaged. However, if you have an aluminum frame and select a heavy glass door, you may need to replace the whole thing with a steel frame. This will best accommodate the weight of your new, heavier sliding patio door.
