DOORSHow much does a sliding glass door cost to replace?

Short answer: replacing a sliding glass door often costs about $2,000 to $6,000 or more, installed. Where you land depends on the frame, the glass package and the size of the opening. Large, multi-panel and premium-frame doors can cost well beyond that.

Sliding glass door cost by frame material

Broad ranges for the door unit itself, before installation:

• Vinyl: about $1,200 to $3,000
• Composite: about $1,800 to $4,500
• Aluminum: about $1,500 to $4,500
• Wood: about $2,500 to $6,000

Installation, trim and disposal are on top. Professional installation typically starts around $500 and can run $1,500 or more for larger doors, brick openings or repairs to the framing and subfloor.

Size and number of panels

A standard 6-foot, two-panel door is the most affordable. Eight-foot-tall, three-panel and four-panel doors cost more, and wider openings may need structural work.

Repair or replace?

• Repair if the door sticks because of worn rollers or a dirty track. Angi lists track and roller replacement at about $110 to $300.
• Replace the glass if one panel is cracked or foggy and the frame is sound. Why glass fogs between panes
• Replace the door if the frame is bent or corroded, it leaks or drafts, it won't lock well, or it's old single-pane or clear glass that heats up your living room.

What to look for in Texas

• Double-pane, Low-E glass with a low Solar Heat Gain Coefficient, especially for west-facing patios. How to read the label
• Multi-point locks and smooth stainless rollers
• A frame that matches your windows in color and line
• Installation sealed like a window, with a sloped, flashed sill
