Why Sightline Windows & Doors North Palm Beach Is Westgate’s Preferred Sliding & Patio Doors Company

Our Sliding & Patio Doors Services in Westgate

Impact Sliding Glass Doors
Westgate sits in Palm Beach County’s wind-borne debris region, roughly 12 miles inland from the Atlantic. That designation means every new sliding door must either be impact-rated or paired with approved shutters. We specify impact sliding glass doors from CWS, ES Windows, and ECO Window Systems, selected by performance tier and price range, not by what we have in stock.
The challenge specific to Westgate: your 1950s-1970s CBS home likely has a 3- to 4-inch masonry buck. A modern impact slider needs 4-9/16 inches of jamb depth. That gap gets closed with on-site concrete modification - a step that never comes up in newer inland subdivisions like Wellington or Royal Palm Beach. We fix the price for that modification in writing before the long-lead order goes to the factory, so the schedule is driven by lead times, not surprises.

Sliding Glass Door Replacement
Original sliders in Westgate’s aging single-family stock are typically single-pane aluminum units with corroded tracks and no impact rating. The high humidity and salt-air UV exposure here accelerate vinyl and rubber seal degradation and corrode older aluminum frames faster than in drier inland climates. When the rollers no longer hold true, the door jumps the track and binds against the fixed panel.
Our replacement process starts with a measured survey you keep. We document the existing rough opening, note any concrete modification required, and specify the exact unit - including jamb depth, design pressure rating, and glazing specification - before ordering. The written quote cannot differ from that survey document. Haven Clause 1.

Impact French Patio Doors
For Westgate homeowners replacing a slider with a swing-door configuration, impact French patio doors offer full ventilation and a wider clear opening when both leaves are active. We stock French door systems from Therma-Tru and ViewLux, with multi-point locking hardware and laminated glass interlayers rated to the correct design pressure for this wind-borne debris zone.
French doors require more swing clearance than sliders, so we verify landing space and traffic patterns during the measured survey. In Westgate’s modest lot sizes, every inch of patio real estate matters. We note door swing, screen storage, and threshold transition height in the written scope before any order is placed.

Screen Door Installation
Most impact sliding and French door systems we install in Westgate include integrated screen options - retractable, sliding, or fixed - specified at the time of order. Retrofitting screens to existing frames is limited by track compatibility; we assess this during survey and document what will and won’t work in the written scope.

AfterTrusted Brands We Service in Westgate
We draw from eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - specified by what the opening requires, not by what is in stock. For Westgate’s impact-rated sliding and patio door needs, we most often reach for CWS and ES Windows in the mid-performance tier, ECO Window Systems where energy efficiency is the priority, and Mr-Glass for specialty laminated configurations. We maintain relationships with regional distributors to minimize lead time variance on long-lead custom orders. Every unit is ordered to the measured rough opening, not pulled from a warehouse rack.
Common Sliding & Patio Doors Problems We See in Westgate Homes

- Corroded aluminum tracks on original sliders. The jalousie-adjacent sliding frames in Westgate’s CBS walls have tracks that no longer hold rollers true, causing the door to jump the track and bind against the fixed panel. High humidity and salt-air UV exposure accelerate this failure mode significantly faster here than in drier climates.
- Shallow masonry bucks forcing inadequate shim space. Non-standard rough openings mean replacement sliders are often forced into openings without proper shim clearance, leading to frame racking, water infiltration at the sill, and premature seal failure. We measure buck depth precisely and price concrete modification in writing before ordering.
- Single-pane glass with no impact rating. Most Westgate sliders are original units that predate Florida’s post-Hurricane Andrew building code overhaul. Any glass break during a tropical storm becomes an immediate breach of the building envelope, triggering internal pressurization and often catastrophic roof or wall damage.
- Failed weatherstripping from thermal cycling and UV. Westgate’s intense UV index and persistent high humidity degrade vinyl and rubber seals faster than inland markets. We specify silicone-based seal systems and proper sill pan flashing on every replacement to address this.
Pricing for Sliding & Patio Doors in Westgate, FL
A typical sliding glass door replacement in Westgate runs $2,800-$4,200 for a standard 6-foot vinyl impact-rated unit with basic concrete modification. Upgrading to an 8-foot multi-slide or adding custom millwork and architectural glass pushes the range to $4,800-$6,500. Impact French patio doors in Westgate typically start around $3,400 for a standard pair and climb to $5,800 with sidelites, transoms, or specialty finishes.
What moves the number: the extent of concrete modification required, the design pressure rating needed for your specific exposure, the glazing specification (clear, tinted, or low-E), and any long-lead custom finishes that drive factory lead times. Labour is rarely the schedule constraint on high-end work - it’s the millwork and glass lead times that set the calendar.
We don’t estimate over the phone. We measure on-site, hand you a written price before any work starts, and that document governs the final invoice.

FAQs - Sliding & Patio Doors in Westgate

Yes, Palm Beach County requires a permit for sliding glass door replacement, and yes, impact-rated glass or approved shutters are mandatory in Westgate’s wind-borne debris zone. We pull the permit, schedule inspections, and pass them as part of our standard scope - documented in the written price before work starts. Call (561) 475-1246 for an exact quote; estimates are free.
Yes, but almost always with on-site concrete modification. Our crew pulled a corroded 6-foot aluminum slider out of a CBS wall on a Westgate Road property and found the original masonry buck was 2 inches shallower than the PGT impact slider’s frame. We used hydraulic chisels to re-buck the opening, then set the new unit with a 1/4-inch reveal and a continuous laminated glass interlayer rated to the correct design pressure for this wind-borne debris zone. The homeowner sent us a photo of their first post-installation wind mitigation inspection report showing full opening protection. We fix the price for this modification in writing before ordering, so there are no surprises. Call (561) 475-1246 to schedule your survey.
Standard impact sliders typically ship in 6-10 weeks; custom finishes, architectural glass, or specialty millwork can extend lead times to 12-16 weeks. The calendar is driven by factory lead times, not labor. We order only after the measured survey is complete and you’ve approved the written price, so the clock starts with accurate dimensions, not a change order mid-stream. Call (561) 475-1246 to begin the survey process.
They can, if your current openings are non-compliant. Florida insurers typically offer wind mitigation credits for impact-rated openings that pass inspection. We document every installation with photos and product specifications to support your inspector’s review. The exact savings depend on your carrier and policy; we can’t promise a specific discount, but we can promise the documentation will be complete. Call (561) 475-1246 for an exact quote; estimates are free.
An impact slider operates on a horizontal track, needs no swing clearance, and works well on Westgate’s modest patios where space is tight. An impact French patio door swings on hinges, offers a wider clear opening when both leaves are active, and requires landing space we verify during survey. Both carry the same impact rating and design pressure certification; the choice depends on your traffic pattern, patio size, and preference. We specify both from our verified manufacturer lines and price each option in writing before you decide. Call (561) 475-1246 to schedule your survey.
