Sliding glass doors can add ventilation and natural light to your home, and even improve its energy efficiency. A new door, on average, costs homeowners $2,564.
If you have an existing sliding glass patio door in need of repair, you may be able to replace only the glass for around $250 to $1,000. You can also replace the roller and tracks for between $110 and $300.
Replacing a single-pane sliding glass door with an insulated one can offer more than an aesthetic improvement. You may also experience significant savings on home energy costs. Over the life of the door, these savings could help recoup most or even all of the original cost.

An energy-efficient sliding glass door can reduce your monthly energy bill by retaining heat and cool air in your home. It’s especially important to find an energy-efficient model, since single-pane glass has poor insulating properties.
The average cost to replace a sliding glass door

Sliding glass door costs by style
Specialty sliding glass doors are typically more pricey than standard models. These styles can add convenience, energy efficiency or weather protection to your home. Here are the most common types of sliding doors, with corresponding price estimates.
- Automatic: $1,000 to $3,500. This type can open or close with a button and may be worth the added cost for a large, heavy door.
- Hurricane-proof: $2,000 to $3,000. These doors have an extra layer of tempered glass to prevent breakage. Some hurricane-prone areas may even require them.
- Soundproof: $2,000 to $3,500. These doors are stronger than regular tempered glass and can reduce noise from outside by as much as 75%
- Double-pane: $2,500 to $3,500. Glass doors with multiple panes provide more insulation and are more energy-efficient.
- Multi-panel: $2,500 to $6,500. This includes telescoping or bifold doors, which can create a wider doorframe opening.
Sliding glass door costs by frame material
Below are the average costs for each type of sliding glass door frame material.
- Vinyl: $300-$1,200. Vinyl is affordable, low-maintenance and durable in most climates. It’s also highly resistant to temperature change, making it very energy-efficient.
- Wood: $1,000-$3,000. Wood is more soundproof than aluminum and may be a better match for your home’s aesthetic.
- Aluminum: $750-$2,500. Aluminum is more affordable than wood and fiberglass. It can withstand severe weather like hurricanes, though it’s not as energy-efficient as other materials.
- Fiberglass: $1,500-$2,500. Fiberglass is sturdy and energy-efficient, though it’s pricier than other materials. It’s also difficult to DIY.
- Composite: $600-$1,200. Composite frames are more durable than wood while keeping the same visual aesthetic.
Other factors that affect sliding glass door costs
Add-ons, upgrades and professional installation can contribute to your total cost. Here are a few factors to consider:

- Screens: $150 to $500. Depending on the company you choose, screens may come with the window.
- Blinds or shades: $150 to $400 when built-in; can cost as low as $20 when purchased and installed separately.
- Tinting: $5 to $30 per square foot. Tinting options usually range from a light tint to a completely reflective glass.
- Locks: $20 to $700. Most windows come with a standard lock, but a custom lock may cost extra.
