Sliding Glass Door Pet Doors: How They Work, Sizing, and Cost Near You in Florida

July 30, 2026

Quick answer: An in-glass pet door installs a pet opening directly into a new glass panel of your sliding door, so the door keeps operating, sealing, and insulating exactly as it did before. In Florida, in-glass pet doors typically cost $900 to $2,500 installed.

How does an in-glass Pet Door work?

An in-glass pet door replaces the glass panel with a new pane made with a corner notch, then fits an insulated pet door into that notch. Because tempered glass can't be cut on site, the notched panel is produced at the manufacturer in advance and installed in a single visit. The result: your sliding door still closes the same, secures the same, and loses no opening space — the only change is a pet door in the bottom corner of the glass.

What sizes are available?

Pet doors are sized to your animal. The installer measures your pet's shoulder height to the floor and shoulder width to determine the correct opening, so the fit is custom to your dog or cat.

Does a pet Door Glass Insert Hurt security or energy efficiency?

No. The glass panel carries the pet door, so the sliding door's lock, operation, and seal are unchanged. Florida Sliding Glass Door Repair uses Security Boss pet doors specifically because the units are well insulated, keeping energy efficiency intact.

Can a Doggie Door be installed in any sliding door?

Most sliding glass doors are good candidates, but some newer vinyl doors are not — cutting into them risks damaging the vinyl frame, so a careful installer will decline those to protect your door.

What makes this service unique in Florida?

Florida Sliding Glass Door Repair is grandfathered in with its supplier for the double-pane pet door with a corner notch and has not found another Florida company able to make the double-pane version. That supplier relationship gives homeowners an insulated, double-pane pet door option that's hard to get anywhere else in the state.

How much does an in-glass pet door cost?

In-glass pet doors run about $900 to $2,500, with most averaging between roughly $1,000 and $3,000 depending on size and glass type.
