We know Westgate’s housing stock. The 1950s-1970s CBS ranches along Westgate Avenue, the rental pockets near Haverhill Road, and the owner-occupied streets south of Forest Hill Boulevard - we’ve measured and replaced windows in all of them. These homes were built before Florida’s High-Velocity Hurricane Zone standards, which means the original jalousie and single-pane aluminum frames you’re living with don’t meet current wind-load requirements. When we arrive, we already know what we’re likely to find: undersized rough openings, cloth-insulated wiring tight against jambs, and failed waterproofing behind stucco that’s been baking in South Florida’s UV for sixty years.

Our Window Replacement Services in Westgate

Full Frame Replacement
Full frame replacement is what most Westgate homes actually need. The original aluminum frames in these 1950s-1970s CBS ranches are nailed directly to the block, with no flange system compatible with modern impact-rated units. We strip to the rough opening, assess the framing for rot or undersizing, and rebuild if necessary - all priced in writing before we order your windows. On a recent job off Westgate Avenue, our crew found cloth-insulated wiring running tight against one jamb. We paused, documented with photos, and priced the licensed electrician’s clearance and rough-opening modification in a written change order. The homeowner approved; we finished with the county inspector signing off on upgraded PGT impact-rated openings with laminated glass interlayer.

Insert Window Replacement
Insert replacement is rare in Westgate, but possible when the existing frame is square, plumb, and structurally sound - usually on a previous replacement that was done correctly. We don’t recommend inserts on original 1960s aluminum because the frames are almost never square after decades of South Florida heat cycling, and the glazing seals have typically failed. If your survey shows insert viability, we’ll document why and price both options. Most Westgate homeowners choose full frame once they see the condition of what’s behind the trim.

Vinyl Replacement Windows
Vinyl frames dominate our Westgate installs because they meet impact-rating requirements at a price point that makes sense for this market’s housing values. We specify CWS and ECO Window Systems vinyl lines for Westgate’s mid-range ranches, with U-factors and SHGC ratings selected for South Florida’s cooling-load dominance. The white or beige vinyl we install won’t corrode like the original aluminum, and the welded corners hold up to the daily expansion and contraction that degrades mechanical corners.

Energy-Efficient Upgrade
Energy-efficient replacement in Westgate means more than low-E glass. It means impact-rated laminated interlayers that block UV and reduce solar heat gain, plus frames with thermal breaks where the budget allows. The original single-pane aluminum in these CBS homes transfers heat directly into the living space; our ES Windows and Mr-Glass energy-efficient lines typically reduce cooling load enough that homeowners notice the difference on their FPL bills within two billing cycles. We document the before-and-after U-factor and SHGC on every energy-efficient quote.

Window Maintenance & Care
Maintenance on original Westgate windows is usually a delaying tactic, but we perform it when the frames are structurally sound and the homeowner needs time to budget for full replacement. We replace failed weatherstripping, clean and lubricate hardware, and re-caulk exterior perimeters. We also document what we find - glazing seal degradation, frame corrosion, rough-opening moisture intrusion - so you have evidence of what’s coming. Every maintenance visit leaves a photo record, standard under Haven Clause 4.

AfterTrusted Brands We Service in Westgate
We draw from eight verified manufacturer lines for Westgate installations: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For this market’s CBS ranches and code-compliance upgrades, we most often specify CWS and ECO Window Systems vinyl impact lines for their balance of wind-load rating and price, with ES Windows and Mr-Glass for homeowners prioritizing energy performance. We don’t stock inventory to move - we specify by what the opening requires, confirmed by our measured survey. Parts and warranty support are available through our Miami office, so a failed balance or lock doesn’t turn into a multi-week wait.
Common Window Replacement Problems We See in Westgate Homes

- Undersized rough openings for modern egress and impact codes. The 24″ by 36″ windows common in 1960s Westgate ranches don’t meet current egress requirements, and the rough openings are too small for the flanged frames of impact-rated replacements. We build rough-opening modification into our contracts where the survey indicates it’s likely.
- Failed waterproofing behind original aluminum frames. Sixty years of South Florida UV and daily heat cycling have degraded the flexible flashings these homes were built with. We find moisture intrusion in the block cavity on roughly half the full-frame replacements we do in Westgate, and we price remediation in writing before touching the wall.
- Outdated electrical running tight to jambs. Cloth-insulated wiring from the 1950s-70s wasn’t planned around modern window depths or impact-rated frame profiles. We document it, price licensed electrician clearance if needed, and never bury code violations behind new trim.
- Landlord-deferred jalousie units flagged by county inspection. Many Westgate rentals still have louvered glass blade windows that are essentially open to wind and rain. These surface when a sale or another trade’s permit pull triggers a Palm Beach County code inspection, and the scope is always bigger than expected because the frames are incompatible with any modern replacement.

FAQs - Window Replacement in Westgate

Yes. Because Westgate is unincorporated Palm Beach County, every window replacement must be permitted through the county building division, not a city hall. We pull permits as standard on every job, coordinate inspections, and ensure your installation meets the 130 mph design wind speed zone requirements. Call (561) 461-2062 and we’ll handle the permit paperwork - it’s included in our scope, not billed separately.
They change when contractors don’t inspect before quoting or don’t build allowances into the contract. On Westgate’s pre-HVHZ CBS ranches, opening the wall routinely exposes undersized rough openings, failed waterproofing, and outdated wiring that weren’t visible during a drive-by estimate. We prevent this by performing a measured survey first, building written allowances into your contract for rough-opening modification and electrical clearance, and pricing any surprise in a signed change order before we touch it. The quote you approve is the quote we stand by - Haven Clause 1 and Haven Clause 5 together.
No - and any contractor who says otherwise is risking your permit approval. Jalousie windows in Westgate fail current Florida Building Code wind-load and egress requirements by design, so replacement is inherently a code-compliance upgrade, not a like-for-like swap. The county inspector will require impact-rated units with proper flanges, which means full-frame replacement and often rough-opening modification. We price this completely in writing before starting, so landlords know the real scope before committing.
Impact windows typically reduce cooling costs by 15-30% compared to single-pane aluminum, depending on your home’s orientation and the SHGC rating selected. Insurance discounts vary by carrier and policy, but most Florida insurers offer wind-mitigation credits for impact-rated openings documented on a uniform wind mitigation form. We provide the product ratings and installation documentation your insurer requires; you submit for the credit. Call (561) 461-2062 and we’ll spec the right U-factor and SHGC for your situation.
We install from eight verified manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux.

Every spec is chosen by what your opening requires, confirmed by our measured survey - not by what’s in stock. Call (561) 461-2062 to schedule your survey and see the product samples.
