Fast, Reliable Sliding & Patio Doors Across Westgate
Custom Windows & Doors in Westgate usually runs between $2,800 and $6,500 installed for sliding patio door replacement, and because Westgate sits in Palm Beach County’s unincorporated wind-borne debris region, nearly every job also triggers impact-rated glazing and a county permit. That’s the part most homeowners don’t see coming. We do, because we’ve been in and out of these 1950s to 1970s CBS ranch homes long enough to know what’s behind the stucco before we open it. If you’re in Westgate and your slider binds, fogs, or won’t lock, call (561) 264-1279. We’ll send a background-checked, uniformed technician who measures twice and puts every line item on paper before any work starts.
Why TruePane Windows & Doors Is Westgate’s Preferred Sliding & Patio Doors Company
Westgate homeowners don’t call us because we’re the cheapest. They call us because they’ve already been through the cheap route once and they’re not doing it again. The homes here – dense pockets of CBS construction off Haverhill Road, north of West Palm Beach, stretching toward North Military Trail – have a particular way of hiding problems behind old aluminum tracks. A door that sticks in July. A threshold that’s quietly rotting. Glass that’s been fogged for three years and everyone just stopped noticing.
We’ve been led by second-generation glazier Dale Kessler since 2008, but the craft tradition runs back many years. That matters in Westgate because this is not a market where you can drop in a stock door and leave. The county’s inspection queue for unincorporated areas is different from the City of West Palm Beach, and the Florida Building Code Section 1609 impact requirements apply to every replacement opening. We know that queue. We pull the permit, we schedule the inspection, and we don’t hand you a door that fails the first look.
Every TruePane job in Westgate comes with the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before our truck leaves your driveway. If the pane is not true, the job is not done. That’s the founding rule, and it governs every install we’ve ever put into a Westgate CBS ranch.
Our Sliding & Patio Doors Services in Westgate
This page covers four doors we install most often in Westgate. Each one has different code, framing, and weatherproofing considerations here, so we quote them separately and in writing. No change orders, no surprise line items. If we find something wrong inside the wall, you approve the fix in writing before we touch it.
Patio Sliding Doors
Window Installation - Westgate projects often start with the standard two-panel patio slider, still the workhorse of post-war floor plans. These homes were built with modest square footage, and the back door was usually a single-pane aluminum unit with no thermal break. By now, most of them are pitted, binding, and non-compliant. We replace them with impact-rated patio sliders that meet Florida Building Code 1609, and we register both warranty layers before we leave. If you’re on a fixed income and the code trigger caught you off guard, we’ll walk you through what the permit actually requires and what it doesn’t.

Panoramic Sliding Systems
Not every Westgate home stays original. We get calls from homeowners who’ve opened up a back wall and want a wide panoramic slider – three, four, even five panels – to connect the living room to a screened patio or a small Florida room. That’s a bigger structural conversation. The opening has to carry the roof load, and in Westgate’s older CBS construction, the existing header is often undersized for anything wider than the original door. We quote that as a line item, not a surprise.

Heavy-Duty Sliding Doors
Impact-rated heavy-duty sliders are the standard recommendation for Westgate, and not only because of the wind code. Salt-laden Atlantic air blows inland across Palm Beach County, and it eats aluminum frames. A heavy-duty slider with a reinforced frame, stainless hardware, and a properly flashed threshold will outlast a builder-grade unit by a decade or more here. We install heavy-duty units from manufacturer lines including PGT and CGI service in Westgate, and we stock the replacement tracks, rollers, and handles our customers ask for most.

Pocket & Barn Doors
Door Installation - Westgate projects like pocket doors give back the floor space that two swinging doors eat up – a real consideration in smaller ranch layouts. But retrofitting a pocket door into a CBS interior wall is not a weekend job. It means opening the block, reframing the pocket, and re-hanging the drywall. We quote it fully loaded so the price you hear is the price you pay. Barn doors are a simpler install but still need proper header blocking, and we hang them so they don’t sag or drift off the track after a year of South Florida humidity.
We also install screen doors built to resist the same salt air that corrodes aluminum – more on that in the FAQs below. And for the full picture on what we offer throughout the region, see our Sliding & Patio Doors service page.

Common Sliding & Patio Doors Problems We See in Westgate Homes
After many years in this trade, and years specifically working Westgate’s unincorporated neighborhoods, these are the four failure modes we see most often on the original doors in these homes:
- Salt-pitted aluminum frames that bind and bend. The Atlantic is eight miles east, and the same breeze that kept these 1950s homes cool also carries salt that eats raw aluminum. We regularly pull Westgate sliders where the track has corroded so badly the sash rides up and over the rail. Often the only real fix is a new impact-rated unit with a thermally broken frame.
- Jalousie and single-pane sliders that drop below code the moment one louver cracks. In Westgate, a single cracked louver on an original jalousie or a cracked pane in a single-pane slider legally triggers a full replacement under the county’s reading of Florida Building Code 1609. Homeowners on fixed incomes get caught off guard by this. We explain it upfront, on the first call, so there are no surprises at permit review.
- Failed threshold waterproofing rotting the subfloor under the track. Tropical humidity is relentless, and on a 60-year-old Westgate house, the flashing tape under the sill pan is long gone. We’ve opened sliders where the subfloor under the track was soft enough to push a screwdriver through. That repair gets priced and approved in writing before we proceed.
- No thermal break and UV-blasted seals. Palm Beach County sun is unkind to old glazing. The rubber seals harden, the desiccant fails, and the glass fogs. A fogged panel is not cosmetic. It means the insulating gas is gone and the unit is no longer doing its job – and it almost always means the rest of the door is on borrowed time.

FAQs - Sliding & Patio Doors in Westgate
Yes, it does. Westgate falls in unincorporated Palm Beach County, and under Florida Building Code Section 1609 any replacement window or door opening in the wind-borne debris region must be either impact-rated or protected by an approved shutter system. The county enforces this on every permit. When we replace a sliding door in Westgate, we pull the Palm Beach County permit and install an impact-rated unit. That is not an upsell. It is the law, and it is non-negotiable. Call (561) 264-1279 and we’ll explain exactly what your opening will require before you commit to anything.
Because they were installed before the modern Florida Building Code existed, and code only applies when the opening is changed. A homeowner can legally live with a non-compliant door until it needs replacement. Most Westgate homes built between the 1950s and 1970s still carry their original aluminum sliders, and many owners simply don’t know they’d need impact glass until something breaks. We handle that disclosure on the first visit, in plain English, with the code section referenced in writing.
The realistic risk is real but manageable. On a 1950s CBS ranch off Haverhill Road, we pulled a Palm Beach County permit to swap a corroded single-pane aluminum slider for an Andersen impact-rated patio door. The inspection opened the wall enough to reveal undersized lintel framing and failed flashing tape, so we flashed and reinforced the jamb to meet wind-borne debris requirements before any finish work – all in writing before we touched it. That is the Westgate reality. Old walls hide things. That’s why our quotes include written allowances for exactly these discoveries, so you’re never ambushed by a change order. When we open a Westgate wall, we know what we’re looking at, and we’ve priced for it.
Yes. Most off-the-shelf screen doors use thin aluminum extrusions and steel mesh that corrode within two or three years of exposure to Palm Beach County’s salt-laden air. We install screen doors with thicker powder-coated frames and fiberglass or stainless mesh that stands up to the same conditions that pit the original sliders on these houses. A proper Westgate screen door runs $350 to $700 installed, and we’ll show you the frame thickness and mesh rating on paper before we order anything.
Visible fog is the late-stage symptom. Earlier signs include condensation between the panes that comes and goes with the weather, a slight oily film on the interior glass, or a pane that feels noticeably warmer than the others on a sunny afternoon. In Westgate’s UV and humidity, a failed seal usually means the desiccant inside the spacer is saturated and the insulating gas has leaked out. At that point the glass is no longer doing its job, and on a door that old, the frame and track are usually close behind it. Call (561) 264-1279 and a technician will come out and tell you straight whether you need glass, hardware, or a full replacement – and you’ll get the answer in writing.
