Fast, Reliable Sliding & Patio Doors Across Westgate
Sliding and patio door replacement in Westgate typically runs $2,800-$6,500 for a standard opening, with most impact-rated installations falling between $4,200 and $6,500 depending on frame condition, glass package, and whether the block buck needs replacement. Most Westgate jobs take two to four days from permit pull to final inspection, though sequencing around well and septic locates can add a day. Call (772) 362-5402 to schedule your free measured survey, and we’ll hand you a written price before any work starts.
We serve Westgate from our South Florida dispatch office, with crews running daily routes through Palm Beach County. The neighborhood’s grid of 1950s-1970s CBS ranch homes, many on half-acre lots with private wells and septic systems, presents a specific set of conditions we’ve documented across hundreds of installations. Our Sliding & Patio Doors team understands that a door replacement here isn’t just about the unit; it’s about whether the rough opening can accept an impact-rated anchor pattern, whether the slab drains away from the wall, and whether the county will accept the product approval number for your specific design wind speed.
Why Sightline Windows & Doors Jupiter Is Westgate’s Preferred Sliding & Patio Doors Company
We’ve installed and replaced sliding and patio doors in Westgate since before the current insurance market made impact-rated openings a requirement for policy renewal, and our Westgate Impact Windows & Doors team knows every permitting path. Our crews know the difference between a 1958 CBS ranch on Purdy Lane and a 1972 split-level near the old Westgate Shopping Center, and they know that the permitting path for each runs through Palm Beach County, not the city.
Westgate customers have left us documented reviews citing our measured surveys, our photo records, and the fact that our written quotes match our final invoices. We don’t ask for trust; we hand you the paperwork. Every technician who arrives at your Westgate home is background-checked, uniformed, and identified by license number before stepping out of the truck, per Haven Clause 3.
Response time to Westgate is typically next-day for measured surveys, with installation scheduling coordinated around county permit turnaround and any required utility locates. Because we pull permits on every job, we don’t start work until the NOA/FL product approval is verified against your site’s calculated wind load.
Our local knowledge is specific. We know that Westgate’s inland position west of I-95 puts it in a heat-island corridor where low-E glass upgrades measurably reduce cooling loads. We know that original aluminum slider tracks in these homes corrode from salt-laden humidity even twenty miles from the coast. And we know that a mini-excavator working near a septic drainfield requires a locate and a sequenced plan before the first block is removed.
Our Sliding & Patio Doors Services in Westgate

Patio Doors
Standard patio door replacement in Westgate starts around $2,800 for a non-impact vinyl or aluminum unit in a sound rough opening. Most Westgate homeowners don’t choose this option. The neighborhood’s aging housing stock and the insurance market’s demands push the practical choice toward impact-rated products with documented Florida Product Approval numbers. When we quote a patio door in Westgate, we scope the frame condition first. Original block bucks in 1960s CBS construction are often too narrow for the anchor spacing required by engineered wind-load calculations, and we flag that in the measured survey you keep.

Impact Sliding Glass Doors
Impact sliding glass doors are the product we install most often in Westgate. A typical PGT or CGI impact slider with laminated glass interlayer and low-E insulated glass unit runs $4,200-$6,200 installed, including permit, inspection, and documented photo record. The performance matters here. Palm Beach County requires NOA or FL# documentation on every permitted replacement, and the product must be rated for your site’s design wind speed, which varies by exposure and proximity to open terrain. Westgate’s older homes often have settled slabs and corroded tracks, so we verify that the new unit’s frame depth matches the available block buck before we write the price. Haven Clause 1: the measurement and the quote are the same document.

Sliding Glass Door Replacement
Sliding glass door replacement in Westgate is rarely a simple swap. Original 1960s aluminum sliders in CBS ranch walls have usually degraded beyond the track; the frame itself has oxidized, the weep system (if there ever was one) is clogged, and the stucco return has cracked from decades of thermal movement. On a half-acre lot off Purdy Lane in Westgate, our crew replaced a rusted 1965 single-pane aluminum slider that had been popping its track every time the family tried to open it during a storm watch. After pulling the block bucks with a mini-excavator to clear the septic setback and regrading the slab for positive drainage, we installed a PGT impact sliding glass door with laminated glass interlayer and a low-E insulated glass unit, and the homeowner’s wind mitigation report then qualified the opening for a Florida Statute 627.0629 insurance credit. That job ran toward the higher end of our range because of the site work, and every dollar was in the written quote before we started.

Impact French Patio Doors
Impact French patio doors suit Westgate homeowners who want the aesthetic of divided lites with the performance rating their insurance carrier demands. Therma-Tru and ViewLux both manufacture impact-rated French door systems with Florida Product Approval numbers valid in Palm Beach County, and we specify by what the opening requires, not by what is in stock. A typical impact French installation in Westgate runs $5,200-$7,800, with the higher end covering wider openings, sidelite configurations, or block buck replacement. The in-swing versus out-swing decision affects both the wind-load rating and the usable interior space, and we document that choice in the measured survey.

Screen Door Installation
Screen door installation in Westgate is usually paired with a primary door replacement, though we do handle standalone screen systems for existing impact-rated sliders. The key consideration is track compatibility; many impact door frames use proprietary screen track profiles, and we verify manufacturer match before ordering. Standalone screen installation typically runs $380-$720.

For this market, we most often quote PGT and CGI for impact sliding glass doors, Therma-Tru for impact French patio doors, and ViewLux for homeowners seeking a specific sightline or divided-lite aesthetic. We don’t stock inventory to move; we order to the measured opening after the survey is complete.

Turnaround from order to delivery is typically ten to fourteen business days for standard sizes, with custom configurations running longer.
Common Sliding & Patio Doors Problems We See in Westgate Homes

- Corroded aluminum slider tracks binding and jumping. Original aluminum slider tracks in Westgate’s CBS ranch walls corrode and pit because of salt-laden humidity, causing the door to bind and jump track, and the narrow block buck often leaves no room for the anchor spacing required by the engineered wind-load calc. The door becomes unusable before it becomes unsafe, but the underlying frame degradation is the real problem.
- Jalousie patio doors leaking at jamb and sill. Jalousie patio doors common on these homes leak at the jamb and sill because the 1950s stucco returns were never flashed or weeped, so wind-driven rain tracks straight into the wall cavity during a tropical system. By the time interior drywall shows damage, the block buck and adjacent framing have been wet for multiple storm cycles.
- Well and septic conflicts during block buck replacement. When a Westgate lot has a private well and septic, an excavator brought in to cut or replace the block buck can crush the drainfield or pierce the well line, so door replacement has to be sequenced around utility locates and site access before the permit is even pulled. We coordinate locates through Sunshine 811 and document the clearance in your job file.
- Slab settlement creating negative drainage toward the wall. Many Westgate ranch slabs have settled toward the house over sixty-plus years, pooling water at the sill plate and accelerating frame corrosion. We grade for positive drainage as part of the replacement scope when the condition exists, and we photograph the before and after.

FAQs - Sliding & Patio Doors in Westgate

Yes. Palm Beach County requires a permit for every window and door replacement, including a single unit, and the product must carry an NOA or Florida Product Approval number with engineered wind-load calculations for your specific site. There is no homeowner exemption for “like-for-like” replacement in this jurisdiction. Call (772) 362-5402 and we’ll verify your product approval and pull the permit as part of our scope.
It can. If the existing block buck needs replacement, the excavation required to cut and remove it must clear your septic drainfield and well line, which means a Sunshine 811 locate and possible hand-digging near those utilities. We sequence this into the job schedule before permit pull, and we document the locate clearance in your file. The locate itself is free; any additional excavation to protect utilities is scoped and priced in the written quote before work starts.
It can qualify you for credits under Florida Statute 627.0629 if the installation is documented in a wind mitigation report by a licensed inspector. The door must be impact-rated, properly permitted, and pass inspection; our documented photo record supports that documentation. We don’t guarantee premium reductions, which vary by carrier and policy, but we do guarantee that our installation meets the technical requirements for credit eligibility. Call (772) 362-5402 to discuss how we document the opening for your inspector.
Low-E insulated glass units with argon fill typically reduce solar heat gain by 40-60% compared to single-pane aluminum sliders, and in Westgate’s inland heat-island corridor west of I-95, that translates to measurable HVAC runtime reduction during summer months. Exact savings depend on your home’s orientation, shading, and insulation, but the SHGC improvement is documented in the product specs we provide. We quote low-E as standard on every impact unit we install.
The block buck, the condition of the surrounding stucco return, and the slab drainage. Original block bucks in 1960s Westgate construction are often too narrow for the anchor spacing required by current wind-load calculations, and corroded aluminum frames may have damaged the surrounding masonry. We verify all three in the measured survey you keep, and we scope any required repairs in the written quote before ordering the door. No work starts until you have the complete price in writing.
Call (772) 362-5402 to schedule your free measured survey. We’ll hand you a written price before any work starts, and every completed job leaves a documented photo record under the 365-Day Done Right Promise.
