Impact Windows & Doors in Westgate, FL - Pricing, Permits & What to Know
Impact window and door replacement in Westgate typically runs $890-$2,400 per opening depending on frame material, glazing package, and whether the existing rough opening requires modification. Most Westgate homes need 8-14 openings replaced, putting whole-house projects between $9,500 and $28,000. Because Westgate is unincorporated Palm Beach County, every job must be permitted through the county building division, not a city hall, and we handle that process start to finish. Call (561) 461-2062 to schedule your measured survey and written estimate.
Why Westgate’s Coastal-Interior Position Dictates What We Specify
Westgate sits in that middle zone - close enough to the Atlantic to catch salt-laden easterlies during storms, far enough inland that some contractors spec standard-grade hardware and call it good. We’ve seen what happens when they do. The CBS ranch homes along Haverhill Road and in the Westgate Estates area were built in the 1960s and 70s with aluminum-frame jalousie windows and plain carbon-steel fasteners. Ten years in, the fasteners bloom with corrosion, the frames pit at the weep holes, and the glazing seals harden from UV exposure and daily heat cycling. The cheap spec always costs more.
Our Impact Windows & Doors team specifies stainless-steel or hot-dip galvanized fasteners for every Westgate opening, marine-grade frame finishes on coastal-exposure elevations, and sealed glazing systems rated for Palm Beach County’s 130 mph design wind speed zone. The price gap between inland-spec and coastal-spec hardware runs roughly $40-$85 per opening. That difference disappears the first time a homeowner replaces corroded standard fasteners and reseals leaking frames.
On a CBS ranch in the Westgate Estates area, our crew replaced original jalousie windows with PGT impact-rated laminated glass units, but the undersized rough openings required jamb modification and a Miami-Dade NOA-approved shim system to meet current egress and design pressure requirements. We finished with low-E insulated glass and stainless-steel fasteners, cutting the homeowner’s cooling load while passing the county’s HVHZ wind-load inspection on the first try.
Why Sightline Windows & Doors Lantana Is Westgate’s Preferred Impact Windows & Doors Company

We’ve completed hundreds of openings in Westgate’s 1950s-1970s CBS housing stock, and the pattern is consistent: original jalousie and single-pane aluminum windows that fail current Florida Building Code wind-load requirements and create life-safety liabilities during hurricane events. Our crews know the county permitting path for unincorporated Palm Beach County properties, and we coordinate dispatch from our Miami office to maintain consistent arrival windows for Westgate appointments.
Our 365-Day Done Right Promise applies to every Westgate installation - written into the Haven Standard, not offered as a courtesy. If it’s not done right, we make it right. Every job leaves a documented photo record, and every customer keeps the measured survey we used to generate the written quote. The price you see before work starts is the price on the final invoice.

Hurricane Impact Windows
Westgate’s 130 mph design wind speed zone means hurricane impact windows aren’t optional upgrades - they’re code-mandated replacements for failed original fenestration. We specify large-missile-impact-rated laminated glass from PGT, CGI, or ES Windows, with design pressures matched to your home’s exposure category. Most Westgate CBS ranches require DP-50 or higher ratings on windward elevations. Every unit carries Florida Product Approval and Miami-Dade NOA documentation for smooth county permitting.

Wind Mitigation & HVHZ Code Compliance
Because Westgate is unincorporated, permits route through Palm Beach County’s building division at 2300 N. Jog Road, not a municipal city hall. We pull permits, schedule inspections, and correct deficiencies if the county inspector flags rough-opening modifications or fastening patterns. Our quotes include permit fees and inspection coordination - no line-item surprise later. For homeowners pursuing wind mitigation insurance discounts, we document opening protection ratings on the standard OIR-B1-1802 form.

Single Hung Impact Windows
Single hung impact windows are the workhorse replacement for Westgate’s original aluminum single-hung and jalousie units. The fixed upper sash and operable lower sash match the sightlines of existing openings while providing laminated glass protection and improved U-factors. We stock Therma-Tru and ECO Window Systems single hung lines in white and bronze extrusions to match common Westgate exterior color schemes. Rough-opening modifications for egress compliance are quoted upfront, not discovered mid-job.

Double Hung Impact Windows
Double hung impact windows suit Westgate homeowners who want operable upper and lower sashes for cleaning and ventilation control. Both sashes tilt inward for maintenance from inside - useful for homes with limited exterior access or security concerns. We specify double hung units from Mr-Glass and ViewLux with reinforced meeting rails and dual weatherstripping to maintain air infiltration ratings after years of operation.

Trusted 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 - specified by what your Westgate opening requires, not by what sits in a warehouse. For the salt-air exposure on eastern elevations near Haverhill Road and the South Military Trail corridor, we favor ES Windows and ECO Window Systems aluminum frames with Kynar 500 fluoropolymer finishes and stainless-steel hardware. Therma-Tru entry systems with impact-rated laminated glass sidelites handle the front-door replacements we see frequently in Westgate’s rental conversions. We don’t stock everything locally, but our Miami office maintains inventory for standard Westgate rough-opening sizes, and non-stock units typically arrive within 10-14 business days with tracking documentation.
Common Impact Windows & Doors Problems We See in Westgate Homes
- Jalousie windows with zero impact rating. Westgate’s remaining louvered glass-blade windows provide no laminated glass interlayer, no large-missile rating, and no design pressure certification. Under 130 mph wind events, the blades detach and become projectile hazards. Every jalousie replacement we quote includes rough-opening assessment for egress compliance.
- Corroded original aluminum frames. Decades of South Florida UV exposure and heat cycling degrade anodized finishes, pit extrusions at weep holes, and harden glazing seals. The frames leak air and water long before they fail structurally. We document frame condition during the measured survey and specify replacement versus retrofit based on actual readings.
- Undersized rough openings from 1960s-70s CBS construction. Westgate’s original window openings often fall short of current egress width and height requirements. Improper shimming to force a modern unit into an old opening voids Florida Product Approval and fails inspection. Our quotes include jamb modification or header adjustment when the measured survey requires it.
- Failed wind mitigation documentation. Homeowners who replaced windows with non-impact units or unpermitted installations can’t produce the product approval numbers insurers require for opening protection credits. We provide Miami-Dade NOA certificates and Florida Product Approval documentation for every impact unit installed.

FAQs - Impact Windows & Doors in Westgate
No - Westgate is unincorporated Palm Beach County, so permits route through the county building division at 2300 N. Jog Road, not a city hall. We pull the permit, schedule inspections, and handle corrections as part of our standard scope. The permit fee is included in your written quote. Call (561) 461-2062 for an exact quote - estimates are free.
Sometimes, but not always. Westgate’s original jalousie openings are frequently undersized by current egress and design pressure standards. We measure every rough opening during the survey and quote jamb modification upfront if the existing dimensions can’t accommodate a code-compliant impact unit. Forcing a unit into an undersized opening voids Florida Product Approval and fails inspection. Call (561) 461-2062 to schedule a measured survey - estimates are free.
Impact-rated windows and doors with Miami-Dade NOA or Florida Product Approval qualify for opening protection credits on the standard OIR-B1-1802 wind mitigation form. The exact premium reduction depends on your insurer and the other four mitigation features on your home. We document product approval numbers and installation photos to support your inspector’s documentation. Call (561) 461-2062 for an exact quote - estimates are free.
Low-E insulated impact glass typically reduces solar heat gain by 40-60% compared to original single-pane aluminum windows. In Westgate’s intense UV and heat-cycling climate, that translates to measurable cooling load reduction - we’ve seen summer electric bills drop 15-25% after whole-house replacement on well-sealed CBS ranches, though results vary with insulation, roof color, and HVAC efficiency. We specify SHGC and U-factor ratings by elevation, not by margin. Call (561) 461-2062 for an exact quote - estimates are free.
Yes - every impact unit we specify for Westgate carries design pressure ratings matched to Palm Beach County’s 130 mph zone and HVHZ requirements. We document DP ratings, Miami-Dade NOA numbers, and Florida Product Approval on every quote. The county inspector verifies installation against these documents at final inspection. Call (561) 461-2062 for an exact quote - estimates are free.
