Impact sliding glass doors and French doors replace your largest openings with laminated-glass units rated for the HVHZ. Cost depends mainly on width, number of panels, glass and frame finish; we price each opening after measuring, because no two openings are the same size.
Configurations

|---|---|
| 2-panel slider | Standard patio openings |
| 3- and 4-panel sliders | Wide openings to pools and lanais |
| Pocket sliders | Panels disappear into the wall for a full opening |
| French doors (in- or outswing) | Traditional look, full-width access when both leaves open |
Thresholds and water performance
Sliders are rated for water resistance as well as wind. Higher sills perform better in wind-driven rain; low-profile sills look cleaner but may need extra drainage detailing. We match the sill to your exposure.
Install day
- Permit issued, with condo or HOA approval on file
- Old door removed and opening inspected
- Opening prepared and sealed
- New frame anchored per the product approval
- Panels set, adjusted and sealed

Condo and HOA approvals
Condo boards often specify frame color, glass tint and even the manufacturer. We prepare the submittal before ordering so the doors arrive approved.
What drives the cost
- Width and height of the opening
- Number of panels and whether any are fixed
- Glass: laminated impact glass, tint and low-E coatings
- Frame color and finish
- Pocket or stacking configurations that need wall work
- Design pressure required for the opening
Sliders vs. French doors

Living with impact doors
Laminated impact glass reduces outside noise and blocks most UV, which helps protect floors and furniture from fading. Impact doors also eliminate the need to install shutters before storms on those openings.
Care and maintenance
- Keep sliding tracks clean of sand and debris
- Lubricate rollers and locks as the manufacturer recommends
- Check weatherstripping each year
- Keep weep holes clear so water drains
