What Are The Factors Affecting The Cost Of Replacing The Sliding Glass Door?

The factors affecting the cost of replacing a sliding glass door include the frame’s material, the number of glass panels, the size, the glass type and thickness, etc. You must be aware of these factors to plan effectively. Read on for detailed explanations of these factors.

1. The Frame’s Material

Aluminum, vinyl, fiberglass, and wood are the most commonly used material for the frame of sliding glass doors. 

  • Aluminum is a popular choice because it is durable, requires less maintenance, and is lightweight. It is also an affordable option. Aluminum sliding glass doors cost $600 – $1000. Although aluminum is energy-efficient, it is prone to heat loss, and only it is perfect for homes in areas with mild temperatures.
  • Fiberglass frames are weather-resistant hence perfect for any weather condition. They come in various styles and colors, require little maintenance, and are durable. Fiberglass is the most expensive option. It costs $1500 – $2500. 
  • Vinyl frames are durable, lightweight, cost-effective, easy to install, and require little maintenance. They can be painted or stained to suit your preference.  Its only major shortcoming is it is prone to warping in extreme heat. Vinyl sliding glass doors cost $300 – $700. 
  • Wood frame is a classic option. They can be painted or stained to match your interior decor. Wood frames are a popular choice because they are good insulators and are long-lasting. However, when exposed to moisture and insects, they warp, chirp, and rot quickly. Wood sliding doors cost $500 – $1500, depending on the type of wood and design.

2. Number of Glass Panels

Another factor that influences the replacement cost of sliding glass doors to a large extent is the number of glass panels. Typically, the higher the number of panels, the higher the price of the door itself and the higher the labor cost. The five standard options are two-panel, three-panel, four-panel, five-panel, and six-panel. 

Replacing a two-panel sliding glass door would be cheaper than replacing a six-panel sliding glass door. A two-panel sliding glass door costs $300 – $1300 (for just the door itself), while a four-panel sliding door costs $2000 – $5000. Depending on the number of panels you want, expect to spend between $700 – $6500 for purchasing the door and installation. 

3. Glass Type, Thickness, and Coating

There are four types of glass used for sliding glass doors and glass doors in general: annealed, tempered, heat-strengthened and laminated glass. Annealed glass is ordinary glass that has not been heat-strengthened or tempered. Annealed glass is the cheapest type available but is more prone to damage.

Heat-strengthened glass is five times stronger than annealed glass and is affordable. Tempered glass is four times stronger than tempered glass, is less prone to damage, and is quite expensive. Laminated is the most substantial. Although it is expensive, go for laminated glass because it is not easily compromised.

The thickness of the glass also affects the price of your sliding door, determining the replacement cost. More material is used to make thicker glass, making it more expensive. The standard glass thickness for sliding glass doors is ⅜ – ½ inches.

Coatings are usually added to glass to make it more durable and resistant to dents. Some coatings like tinting help reduce the amount of light passing through the glass. Typically, the coated glass would be much more expensive than uncoated glass.

4. Size

Typically, the larger the door, the higher the price, which increases the replacement cost. The size of each panel affects the price of the door. An eight-foot-tall two-panel door would be more expensive than a two-panel sliding door just six feet tall.

5. Hardware And Hardware Material

The number of hardware to be replaced and the quality of the material used will affect the total replacement cost. Additional features like pet dogs, soft-close systems, etc.., add to the replacement cost.
