Quick answer: A new two-panel aluminum sliding glass door installation in Florida costs about $4,000 to $6,000, all-inclusive (permitting, framework, tear-out, and install), and takes roughly four to eight weeks from first call to finished job. Aluminum sliders outlast vinyl in Florida's heat, and a permitted, laser-leveled install is what separates a door that lasts decades from one that fails in a few years.
When is it time to replace a sliding glass door?
Replace the whole door when repair no longer makes sense: the door looks cosmetically worn or corroded, it's dilapidated from age, or you want better energy efficiency. Aluminum frames in Florida rarely look right again once they've degraded, and a door that has reached that point is usually more cost-effective to replace than to keep repairing.
Aluminum vs. vinyl: which is better in Florida?
Aluminum is the better sliding door material for Florida. Vinyl doors swell in the state's heat and humidity, and a damaged vinyl panel can't be repaired — which is why installers call vinyl doors "throwaways" that can deteriorate in three to five years. Vinyl saves only about $500 to $1,000 over aluminum, so the small savings rarely justifies the shorter lifespan. Florida Sliding Glass Door Repair installs MI Windows & Doors aluminum sliders as its preferred product, along with select PGT and CWS models.
How much does a new sliding glass door cost in Florida?
A two-panel aluminum installation runs $4,000 to $6,000 all-inclusive. That price covers permitting, framework, tear-out of the old door, and the new install. Vinyl runs only slightly less. Costs rise with more panels, impact glass, and larger openings.
How long does installation take?
Plan on about four to eight weeks from the first call to the finished job, depending on the manufacturer's lead time. Every new installation begins with an on-site measurement visit.
What does a quality installation include?
A professional installer handles all permitting — skipping permits is illegal in Florida and a common corner cut by cheaper contractors. Florida Sliding Glass Door Repair uses lasers on every install to set the door perfectly plumb so it glides without resistance, tarps off the home to control dust and debris, and preps the opening to Florida hurricane standards. When an opening isn't square, the crew undersizes the new door slightly and builds it out so the finished door is 100% accurate.
What goes wrong with a cheap Sliding Door installation?
A poor install shows up fast: the door isn't plumb so it drags, the frame isn't insulated properly, it isn't secured with concrete screws, or the bottom isn't leveled — leaving a "roller coaster" track that holds water. The biggest mistake homeowners make is choosing a problematic manufacturer to save money, then living with a door that never operates smoothly.
