The table below shows typical installed costs for common PATIO_DOOR sizes and materials.
| Door size | Vinyl | Aluminum | Wood | Fiberglass |
| 5 ft x 6 ft 8 in | $800 to $1,500 | $700 to $1,200 | $1,800 to $3,000 | $1,500 to $2,500 |
| 6 ft x 6 ft 8 in | $1,000 to $1,800 | $800 to $1,500 | $2,000 to $3,500 | $1,800 to $3,000 |
| 8 ft x 6 ft 8 in | $1,500 to $2,500 | $1,200 to $2,000 | $2,500 to $4,500 | $2,200 to $3,500 |
| 9 ft x 6 ft 8 in (3-panel) | $2,000 to $3,500 | $1,800 to $2,800 | $3,500 to $5,000 | $2,800 to $4,500 |
The installed price typically includes the door unit, frame, tempered glass, weatherstripping, hardware, professional installation, and basic exterior trim around the opening. Additional costs may include interior trim work, exterior siding repairs, and disposal of the old door. These extras add $100 to $400 to the total project cost depending on the condition of the existing opening and the complexity of the installation work required.
Cost by Frame Material
The frame material is the biggest factor in the cost of a patio door replacement. Each material offers different benefits in terms of durability, insulation, maintenance, and price. The best sliding door choice for your home depends on your climate, budget, and aesthetic preferences for your property.
Vinyl patio door $800 to $2,500 installed. Vinyl is the most popular choice for patio doors because it is affordable, energy-efficient, and maintenance-free for the homeowner. Vinyl frames do not rot, rust, or need painting like wood frames do. They provide good insulation performance with multi-chambered designs that trap air for thermal efficiency. Vinyl doors last 20 to 40 years and are the best value for most homeowners.
Aluminum patio door $700 to $2,000 installed. Aluminum is lightweight, strong, and affordable. However, aluminum conducts heat and cold easily, making it the least energy-efficient option. Aluminum patio doors are commonly used in warm climate regions of the country where insulation is less critical for the overall home comfort. They last 20 to 40 years but may corrode in coastal areas.
Wood patio door $1,800 to $5,000 installed. Wood provides natural insulation and a traditional look that adds value to the home. Wood doors can be painted or stained any color. They require regular maintenance including painting or staining every three to five years. Wood doors last 30 to 60 years with proper care and are the preferred choice for historic homes.
Fiberglass patio door $1,500 to $4,500 installed. Fiberglass is stronger than vinyl and offers better insulation. Fiberglass frames expand and contract at the same rate as glass, reducing stress on the seals and preventing air leaks. They last 40 to 60 years and can be painted any color to match the home exterior. Fiberglass doors are the best choice for homeowners who want maximum durability and energy efficiency over the long term.
Glass Options for Sliding Doors
The type of glass in your door affects the cost, energy efficiency, and comfort of your home. Double-pane glass is standard, but Low-E coating, argon gas fill, and triple-pane glass add to the cost and improve performance. The right glass choice depends on your climate and energy goals.
Double-pane tempered glass is included in standard PATIO_DOOR pricing. It provides basic insulation and safety. Tempered safety glass material is four to five times stronger than standard glass and breaks into small, dull pieces instead of sharp shards. All PATIO_DOORs are required by code to use tempered glass for safety.
Low-E coating adds $50 to $150 to the cost of a PATIO_DOOR. Low-E coating reflects infrared heat back into the room in winter and blocks solar heat in summer. It also blocks UV rays that fade furniture and flooring. Low-E coating is recommended for all PATIO_DOORs in every climate because the energy savings typically exceed the added cost within two to three years.
Argon gas fill between the panes adds $30 to $80 to the cost. Argon gas provides better insulation than air and improves the overall energy efficiency of the patio door. Double-pane patio doors with Low-E coating and argon gas fill offer the best balance of cost and performance for most homeowners looking for energy savings.
Triple-pane glass adds $200 to $500 to the cost of a PATIO_DOOR. Triple-pane doors provide the best insulation and noise reduction. They are recommended for very cold climates or homes near busy roads. The higher cost of triple-pane glass is offset by energy savings over time in cold climates.
Installation Process and Cost
The installation cost for a PATIO_DOOR is typically $200 to $800, depending on the door size, frame material, and the complexity of the installation. The installation cost is usually included in the total installed price quoted by the contractor. Professional installation is strongly recommended for PATIO_DOORs because of the weight of the door and the precision required for proper operation.
The installation process takes four to eight hours for a standard PATIO_DOOR replacement. The old door is removed first, then the opening is inspected for damage, and the new door is set in place, leveled, shimmed, and secured. The gaps around the frame are filled with expanding foam insulation to prevent air leakage. New trim is installed on both the interior and exterior sides of the door. The door is tested for smooth sliding operation and proper sealing of the door.
New construction installation costs less than replacement installation because there is no old door to remove and the framing is built to fit the new door. Replacement installation requires removing the old door, inspecting the rough opening, and potentially repairing damage to the framing or siding. These additional steps add $100 to $300 to the installation cost.
A door installation contractor with 22 years of experience explained: “The most common problem we see with PATIO_DOORs is improper installation of the flashing and weatherstripping. Water leaks around PATIO_DOORs are almost always caused by incorrect flashing installation, not by a defect in the door itself. I recommend hiring a contractor who specializes in door installation rather than a general handyman, because the flashing details are critical for preventing water damage to the wall and floor around the door.”
Factors That Affect Sliding Doors Cost
Several factors affect the patio door cost and installation beyond the door size and frame material. Understanding these factors helps you get accurate quotes and avoid unexpected expenses during the installation process.
- Rough opening size: Standard sizes cost less than custom sizes
- Existing damage: Rot or water damage adds repair costs
- Siding type: Stucco or brick requires more labor to cut and seal
- Second story: Upper floor installation requires extra labor and equipment
- Permit fees: Most areas require a permit for door replacement
Custom sizes cost 20 to 50 percent more than standard sizes. Standard PATIO_DOOR sizes are 5 feet, 6 feet, and 8 feet wide. Any width outside these standard door sizes is considered custom and requires a special order door, which costs more and takes longer to arrive. Custom-sized doors also require more labor to install properly because the rough opening may need modifications to fit the new door unit correctly.
The condition of the existing opening affects the cost. If the old door frame has rot or water damage, the framing may need repairs before the new door can be installed. Rot repair costs $200 to $1,000 depending on the extent of the damage found after the old door is removed. Siding repair around the new door adds $100 to $500 if the new door is a different size than the old door.
