Our Sliding & Patio Doors Services in Westgate

Impact Sliding Glass Doors
Westgate sits in Palm Beach County’s high-wind design zone, just north of the stricter High Velocity Hurricane Zone that governs Miami-Dade and Broward. This matters for product selection. We specify FBC-approved impact sliders with valid NOA documentation, but some HVHZ-exclusive restrictions don’t apply here, which can affect both product availability and cost. On a concrete-block home off Westgate Avenue near the canal, our crew pulled a builder-grade aluminum slider whose track had pitted through from salt-laden air and whose laminated glass interlayer had begun to cloud at the edges; we reframed the opening, set a PGT impact-rated slider on a marine-grade sill pan, and replaced the neighboring jalousie panel with a solid impact window to bring every opening into compliance. The homeowner’s wind mitigation report went from deficient to fully credited, and the new low-E insulated glass unit cut afternoon heat load enough that the family noticed the difference on the first utility bill.

Sliding Glass Door Replacement
Most Westgate homes built between 1960 and 1985 carry original aluminum-frame sliding doors with single-pane glass and steel rollers. Salt air near Westgate’s canal corridors attacks both. The track pits. The rollers seize. The sash drags. Eventually the interlock no longer seals against wind-driven rain. We don’t swap panels into rotted frames. Our replacement scope includes full frame removal, sill pan inspection or replacement, and installation of a unit sized to the actual opening, not the nominal size of what failed.

Impact French Patio Doors
French patio doors in Westgate need the same impact-rated glazing as sliders, but the hinged operation introduces additional load paths that standard units don’t handle. We specify multi-point locking hardware and reinforced jambs rated for the design pressures Palm Beach County requires. For homes near the L-8 Canal or other water features where salt air concentrates, we order marine-grade hardware finishes at specification, not as an upgrade. The price gap between coastal-spec and inland-spec hardware is real, and we name it in writing before you decide.

Screen Door Installation
New impact sliders and French doors include factory screen tracks, but many Westgate homeowners need standalone screen door solutions for existing openings. We measure for proper fit on out-of-square block walls, specify corrosion-resistant framing, and document the installation with the same photo record as full door replacements.

AfterTrusted Brands We Service in Westgate
We draw from eight verified manufacturer lines, specifying by what the opening requires rather than what sits in a warehouse. For Westgate’s salt-air exposure and impact requirements, we regularly install ES Windows and ECO Window Systems impact-rated sliders with marine-grade hardware packages, and Therma-Tru fiberglass French door systems where rot resistance matters. Mr-Glass laminated products handle the glazing spec when custom sizes are needed for non-standard block openings. Every unit arrives with NOA documentation for Palm Beach County permit submission, and we stock common replacement hardware locally for Westgate service calls.
Common Sliding & Patio Doors Problems We See in Westgate Homes

- Salt-air pitting and galvanic corrosion on aluminum slider tracks and standard steel rollers. The door binds, then the sash drags and the interlock no longer seals. We specify stainless or hot-dip galvanized hardware and marine-grade sill pans for replacements, not standard indoor-grade components that fail within five years here.
- Original jalousie or aluminum single-pane openings adjacent to a new patio door. The new slider is impact-rated but the surrounding openings still fail design pressure, so the whole wall assembly remains non-compliant. This is the scope reality that catches Westgate homeowners off guard: every opening in the wall must meet code, not just the one being replaced.
- Hollow-core or builder-grade exterior doors attached to patio door assemblies. They warp in Westgate’s humidity, breaking the threshold seal and letting wind-driven rain reach the jamb and subfloor. We see this where Florida rooms or enclosed patios were added to original construction without upgrading the connecting door.
- Clouding laminated glass interlayers from thermal cycling and UV exposure. Westgate’s afternoon sun loads are severe, and older laminated units without proper edge sealing degrade at the perimeter. Replacement requires full sash or full unit replacement, not glass-only service.

FAQs - Sliding & Patio Doors in Westgate

No. Westgate is in Palm Beach County’s high-wind design zone under the Florida Building Code but sits just north of the High Velocity Hurricane Zone that governs Miami-Dade and Broward. Your replacement needs FBC-approved impact-rated products with valid NOA documentation, but some HVHZ-exclusive product restrictions do not apply, which can expand product options and sometimes reduce cost. Call (561) 286-4734 and we’ll confirm the exact code requirements for your address.
The whole frame almost always has to come out. Westgate’s original aluminum frames are typically corroded at the sill, out of square from block settlement, and sized for single-pane glass that no longer meets code. A new impact-rated sash in an old frame won’t seal properly and won’t pass inspection. Our measured survey documents the full scope before you commit. Call (561) 286-4734 to schedule.
They must be replaced. There is no code-compliant way to make jalousie panels impact-resistant. When we replace a patio door in a wall that includes jalousie windows, we reframe those openings and install solid impact-rated units to bring the entire wall assembly into compliance. This scope reality routinely surprises Westgate homeowners who expected a simple door swap. We identify this in the initial measured survey and name the full price in writing. Call (561) 286-4734 for a free estimate.
It can, if the installation is documented on a wind mitigation report that shows impact-rated glazing on all openings. Many Westgate homeowners see reductions when they move from non-compliant original construction to full wall assembly compliance. The key is that every opening in the wall must meet code, not just the new door. We document our work with the photo record and product specifications your inspector needs. Call (561) 286-4734 to discuss your specific situation.
Homeowners in Westgate’s concrete-block homes typically see measurable reductions in afternoon heat load after installing low-E insulated impact glass, with some reporting first-bill differences they noticed without prompting. The exact savings depend on home orientation, shading, and how many openings are upgraded. Single-door replacement helps; full-wall or whole-home upgrade compounds the effect. Call (561) 286-4734 for a measured survey that includes thermal performance specifications for your specific product options.
