AfterFast, Reliable Sliding & Patio Doors Across Westgate
Sliding and patio door replacement in Westgate runs $2,800-$6,500 for most impact-rated units, with permits pulled through Palm Beach County’s unincorporated building division and typical completion in two to four days once materials arrive. We coordinate dispatch from our Miami office and keep crews working regularly in Westgate’s 1950s-1970s CBS ranch neighborhoods - the same homes where original aluminum sliders and jalousie panels are still failing county code. Call (561) 461-2062 and we’ll schedule a measured survey; the written price you receive is the price on the invoice.
Why Sightline Windows & Doors Lantana Is Westgate’s Preferred Sliding & Patio Doors Company

Westgate customers find us through three-star review deep-dives and neighbor referrals in the CBS ranch pockets off Westgate Avenue and around Haverhill Road.

Our Sliding & Patio Doors Services in Westgate
Patio Doors
Standard patio door replacement in Westgate’s older housing stock almost always becomes a code-compliance upgrade. The original openings in 1960s CBS ranches were built before Palm Beach County’s current HVHZ standards, meaning the rough opening is frequently undersized for modern egress and impact requirements. We measure first, identify whether re-framing is needed, and write that scope into the fixed-price contract - not as a surprise change order.
Impact Sliding Glass Doors
Westgate sits in the county’s 130 mph design wind speed zone. Non-impact aluminum frames and jalousie panels are a life-safety liability here, not a preference. We specify impact sliding glass doors from PGT, CGI, and CWS with laminated glass interlayers rated to the county’s design pressure requirements. Every unit carries a documented performance spec - U-factor, SHGC, and DP rating - that the county inspector can verify against the permit.
Sliding Glass Door Replacement
The most common call we get in Westgate is a slider that won’t roll. Usually it’s a 1960s or 1970s aluminum unit whose track has corroded into the slab. What looks like a simple replacement often reveals an undersized rough opening, a rusted sill pan, and failed waterproofing behind the frame. We inspect for these conditions during the measured survey and write allowances into the contract - priced and approved before we touch the wall.
Impact French Patio Doors
For Westgate homeowners replacing a fixed panel or upgrading from a non-impact slider, impact French patio doors provide full opening width with the same missile-impact and cyclic-pressure ratings required by the county. We source these through ES Windows and ECO Window Systems, specifying by performance tier and price range rather than by what happens to be in stock. The measured survey determines the exact unit; the quote reflects the exact spec.
Screen Door Installation
Screen doors on Westgate’s new impact sliders are measured to the exact jamb depth and track profile of the primary door unit. We don’t retrofit generic screens onto custom openings. The measured survey captures the specification; the written quote names the manufacturer and the part number.

BeforeAfterTrusted Brands We Service in Westgate
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - and specify by what the opening requires, not by margin. For Westgate homes, we most often quote PGT and CGI for impact sliding glass doors at the higher performance tiers, CWS and ES Windows for mid-range impact French patio doors, and ECO Window Systems where the budget and the wind-load requirements align. Parts are sourced through South Florida distribution, not drop-shipped, so lead times stay predictable and warranty claims stay local.
Common Sliding & Patio Doors Problems We See in Westgate Homes
- Corroded aluminum tracks fused to the slab. In 1960s-70s CBS ranches off Westgate Avenue and Haverhill Road, original slider tracks have welded themselves to the concrete through decades of salt-air exposure and daily heat cycling. The door won’t roll. Worse, the rough opening beneath is too small for any modern impact-rated unit without re-framing the jamb and header.
- Failed sill pans and zero waterproofing. Decades-old patio doors in Westgate’s rental stock were installed without proper flashing or drainage planes. Wind-driven rain pours into the block wall cavity, rotting the bottom plate and wicking up the studs. A “simple” replacement becomes a sill-pan upgrade, a drainage repair, and often a section of wall remediation.
- Non-impact jalousie panels flagged by county inspectors. Many Westgate rentals still carry jalousie windows and doors - louvered glass blades that are essentially open to wind and rain. Landlords defer replacement until a Palm Beach County code inspector flags them during a sale or a permit pull on another trade. By then the frame is too degraded to accept a stock impact door, and the rough opening needs rebuild.
- UV-degraded glazing seals and weatherstripping. South Florida’s intense sun and daily heat cycling cook the glazing seals on older non-impact units. The glass fogs. The interlayer separates. The weatherstripping crumbles. In Westgate, this happens faster than in coastal zones because the inland heat builds with less breeze to dissipate it.
Pricing for Sliding & Patio Doors in Westgate, FL
A standard sliding glass door replacement in Westgate typically runs $2,800-$4,200 for a mid-range impact-rated unit, including permit, installation, and basic trim. Impact French patio doors range $4,500-$6,500 depending on width, hardware, and whether the rough opening requires modification. Re-framing, sill-pan replacement, or drainage remediation adds $800-$2,400 - but we identify these conditions during the measured survey and write them into the fixed-price contract, not as later change orders.
What moves the price: the manufacturer line (PGT and CGI command premium pricing for higher DP ratings), the glazing package (low-E, argon fill, laminated interlayer thickness), and the condition of the existing frame and waterproofing. Every quote includes the measured survey document you keep, the written scope, and the photo record on completion. No quote differs from the survey.

FAQs - Sliding & Patio Doors in Westgate
Yes. Because Westgate is unincorporated Palm Beach County, all sliding and patio door replacements must be permitted through the county’s building division, not a city hall. The county inspector verifies impact rating, egress compliance, and proper flashing. We pull the permit as part of our scope, schedule the inspections, and pass them before final payment. Call (561) 461-2062 to schedule a measured survey - estimates are free.
The rough opening in a 1960s or 1970s CBS ranch is almost always too small for a modern impact-rated unit, and the track corrosion, failed sill pan, and degraded waterproofing we find beneath the old frame require remediation before any new door goes in. We inspect for these conditions during the measured survey, write the re-framing and flashing scope into the fixed-price contract, and price it in writing before touching your wall. Call (561) 461-2062 for an exact quote - estimates are free.
Three things: corroded aluminum tracks fused to the slab from decades of salt-air and heat cycling; UV-degraded glazing seals that fog the glass and crumble the weatherstripping; and wind-driven rain penetrating failed sill pans into the block wall cavity. In Westgate’s inland heat, the UV damage accelerates. The track corrosion is nearly universal in original 1960s-70s units. Call (561) 461-2062 for an inspection - estimates are free.
Yes. Impact-rated sliding glass doors with a documented design pressure rating meet the Florida Building Code requirements for wind mitigation discounts on homeowner’s insurance. We provide the product approval documentation, the permit, and the inspection report that your insurer requires. The credit varies by carrier and policy. Call (561) 461-2062 and we’ll explain what documentation we deliver - estimates are free.
On a 1968 CBS ranch off Westgate Avenue, our crew pulled a failed original aluminum slider whose track had corroded into the slab and found the rough opening undersized for any impact-rated unit, plus a rusted-out sill with zero waterproofing and a dated wiring run crossing the threshold. We re-framed and flashed the jamb, upgraded the sill pan, wrote a fixed allowance for unforeseen framing into the contract, and set a PGT impact sliding glass door with laminated glass interlayer rated to the county’s 130 mph design pressure - priced and approved in writing before we touched the wall. That’s how we handle it on every job. Call (561) 461-2062 to schedule your measured survey - estimates are free.
