Fast, Reliable Impact Windows & Doors Across Lantana
Impact window and door installation in Lantana, FL typically runs $1,200-$3,800 per opening depending on frame type, glazing specification, and whether the original opening requires full reframing. Most Lantana homes built between the 1950s and 1970s need full-frame tear-outs rather than sash swaps, which pushes scope and price above what you’d see in newer inland communities. Call (561) 461-2062 to schedule your free measured survey - the written quote you receive is the same document we build from, with no change orders.
We serve Lantana from our Lantana dispatch coordination through the brand’s Miami office, with crews running daily routes through the town’s two-square-mile footprint. That tight geography works in your favor: we’re rarely more than ten minutes from any call. We know the parking constraints on Ocean Avenue, the HOA notification requirements in the condominium clusters near the Intracoastal, and the specific failure modes that salt-air corrosion inflicts on standard hardware within a few seasons.
Why Sightline Windows & Doors Lantana Is Lantana’s Preferred Impact Windows & Doors Company
Lantana’s housing stock is unlike anywhere else in Palm Beach County. The concentration of 1950s-1970s CBS stucco homes still carrying original jalousie windows and corroded aluminum frames means every job here requires specific expertise in full-frame replacement, marine-grade specification, and Palm Beach County’s impact-rated glazing enforcement. We’ve completed hundreds of openings in Lantana since 2012, and the documented photo records from those jobs show the same pattern repeatedly: salt-oxidized pivots, rusted steel thresholds, and inspectors who will not sign off until every jalousie is gone.
Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. The person at your door matches the person on our records. We don’t subcontract to unverified labor, and we don’t send salespeople who can’t read a sightline measurement.
Calls to (561) 461-2062 are answered by a live person, 24/7. Not a callback window. Not a voicemail queue that promises a response within 24 hours. A live operator who can schedule your measured survey or connect you directly with our Impact Windows & Doors team.
The 365-Day Done Right Promise applies to every Lantana installation. If it’s not done right, we make it right - written into the Haven Standard, not offered as a courtesy. That promise is backed by the documented photo record you receive at completion, showing every phase from rough opening to final seal.
Our Impact Windows & Doors Services in Lantana

Hurricane Impact Windows
Lantana sits in Palm Beach County’s wind-borne debris region, which mandates impact-rated glazing on all new and replacement windows and doors. Our hurricane impact windows carry Florida Product Approval and Miami-Dade NOA documentation - the same certificates Palm Beach County inspectors verify before signing off. We specify PGT and CGI lines for Lantana’s coastal exposure, with laminated glass interlayers and marine-grade hardware that resists the salt-air corrosion standard aluminum frames succumb to within a few seasons.

Wind Mititation & HVHZ Code Compliance
Every permitted window and door replacement in Lantana requires compliance with the High Velocity Hurricane Zone provisions adopted by Palm Beach County. We handle the permit pull, the inspection scheduling, and the wind mitigation documentation your insurance underwriter needs. On a 1958 CBS stucco home off Dixie Highway near the Lantana bridge, our crew tore out original aluminum jalousie windows on the Intracoastal-facing wall - the louver pivots were seized with white salt oxidation and the steel door threshold had rusted into the slab. We reframed the rough openings, set PGT impact-rated units with a laminated glass interlayer and marine-grade hardware, and used a Therma-Tru fiberglass door with a composite threshold. The tight lot meant we staged the dumpster and material in the driveway with a one-lane traffic plan, and the inspector signed off once the jalousies were gone and the new units carried their Florida Product Approval and wind mitigation documentation.

Single Hung Impact Windows
Single hung impact windows are the workhorse replacement for Lantana’s original jalousie and single-pane aluminum units. The fixed upper sash and operable lower sash simplify the installation on tight lots where staging space is limited - we don’t need the extended workspace a double hung requires for both sashes to tilt in. We specify CWS and ECO Window Systems single hung lines for Lantana’s mid-range price tier, with U-factors and SHGC values matched to the cooling load of unshaded CBS construction.

Vinyl Impact Windows
Vinyl frames don’t corrode. In Lantana’s salt-air environment, that matters more than the initial price difference. We’ve pulled too many oxidized aluminum frames off Intracoastal-facing walls to recommend standard aluminum for coastal exposure. Our vinyl impact windows from ES Windows and ECO Window Systems carry the same impact ratings and Florida Product Approvals as aluminum alternatives, with welded corners and multi-chamber construction that outlasts corroded metal in this specific climate.

Double Hung Impact Windows
Double hung impact windows suit Lantana’s second-story additions and converted attic spaces where top-down ventilation matters. Both sashes tilt in for cleaning, which is useful on tight lots where ladder placement is restricted by property lines or neighboring structures. We specify these where the opening geometry and ventilation requirement justify the additional cost over single hung.

Horizontal Roller & Sliding Impact Windows
Horizontal roller windows fit the wide, low openings common in Lantana’s 1960s ranch additions and Florida room conversions. The roller mechanism requires precise sill leveling - more critical on older slabs that have settled unevenly. We measure every sill plane with a laser level during our survey and note any shimming requirement in the written scope.

AfterTrusted Brands We Service in Lantana
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - and we specify by what the opening requires, not by what is in stock. For Lantana’s coastal exposure, we favor CGI’s aluminum impact line with Kynar 500 finish for its salt-spray resistance, and ECO Window Systems’ vinyl frames for homeowners prioritizing long-term corrosion immunity over initial cost. CWS supplies our mid-range single and double hung specifications. We don’t push proprietary brands or house lines; the written quote names the manufacturer, the series, and the performance values, and you verify them against the Florida Product Approval database before we order.
Common Impact Windows & Doors Problems We See in Lantana Homes

- Seized jalousie pivots with white salt oxidation. The louvered glass units common on blocks off Dixie Highway have no weather seal and zero design pressure. Their aluminum pivots seize solid within a decade of salt-air exposure. Repair is impossible - the units cannot be brought into code compliance - and Palm Beach County inspectors will reject any permit that includes them.
- Rusted steel door thresholds bonded to the slab. Original exterior doors in Lantana’s 1950s-1970s homes often used steel thresholds without composite or fiberglass separation. Salt air accelerates the rust, and by the time the homeowner notices sticking or water intrusion, the threshold has fused to the concrete. Full removal requires grinding and reframing.
- Standard aluminum frame oxidation on Intracoastal-facing walls. Even impact-rated aluminum frames without marine-grade anodizing or Kynar finish show pitting and seal failure within five to seven years at this salt proximity. We see this failure mode faster in Lantana than in Greenacres or suburban Boynton Beach, where the extra inland distance measurably reduces corrosion rates.
- Permit rejection of attempted sash swaps on jalousie openings. Homeowners sometimes request a minimal “replace the glass” approach to control cost. Palm Beach County does not allow this - the original opening system lacks the structural rating, and the inspector will flag it before the first nail. We price full-frame replacement from the start to avoid mid-job scope changes.

FAQs - Impact Windows & Doors in Lantana

They all have to come out. Jalousie windows have zero design pressure rating and no Miami-Dade NOA, so Palm Beach County inspectors will not approve them on any permitted replacement project. We’ve attempted sash swaps on these openings; every one has been rejected at inspection, forcing a costlier mid-job reframe. We price full-frame tear-out from the start. Call (561) 461-2062 for a free measured survey and written scope.
Lantana’s position directly on the Intracoastal Waterway, with the Atlantic less than a mile east, creates sustained salt-air exposure that standard aluminum hardware cannot withstand. We’ve measured the difference: standard hinges and locks show oxidation failure in five to seven years here, versus twelve to fifteen in Greenacres or western Boynton Beach. We specify marine-grade stainless or Kynar-finished hardware on every Lantana job as standard, not as an upgrade. Call (561) 461-2062 to review hardware specifications on your quote.
Tight lots off Dixie Highway and Ocean Avenue restrict dumpster placement, material staging, and crew parking, which adds labor hours to the job. We address this in our measured survey by photographing access constraints and noting them in the written scope - no surprise charges when the panel truck arrives. On some jobs, we coordinate with neighbors for temporary driveway access or schedule material delivery in smaller loads. The quote reflects what we measured, not what we guessed. Call (561) 461-2062 to schedule your survey.
Yes, if they are being replaced under permit. Palm Beach County’s wind-borne debris region designation mandates impact-rated glazing on all new and replacement windows and doors in Lantana. Existing non-impact units are grandfathered until you trigger a replacement permit. We pull the permit, we specify the rated product, and we deliver the Florida Product Approval documentation your inspector and insurance underwriter require. Call (561) 461-2062 to confirm your project’s compliance path.
Impact windows can reduce your windstorm insurance premium through the wind mitigation credits Florida insurers apply for rated opening protection, and they reduce cooling load by replacing single-pane or jalousie units with low-SHGC, low-U-factor glazing. The exact savings depend on your current construction, your insurer’s credit schedule, and the specific products specified. We document the performance values on every quote so you can verify credits with your agent before ordering. Call (561) 461-2062 to review the numbers on your specific home.
