cost of patio doors installed
1 Installation can bring the total cost to $1,000-$5,500 or more.  Expect costs to double for impact-resistant patio doors (sliding, French-style or single hinged) that can withstand hurricane-force winds. Mike Davidson Construction in Florida estimates that installing a 9' impact-resistant sliding glass door costs about $3,700, compared to $1,800 for tempered glass.
