Fast, Reliable Impact Windows & Doors Across Lantana
Impact window and door installation in Lantana typically runs $1,200-$3,800 per opening depending on frame type, glazing spec, and whether the original CBS rough opening needs modification. Most Lantana homeowners with 1950s-1970s homes need full-frame replacement to meet current Palm Beach County wind-load codes, not just glass swaps. Call (561) 421-3844 and we’ll schedule a measured survey you keep, with a written price before any work starts.
We serve Lantana from our South Florida scheduling office, with crews running daily routes through the 33460 corridor east of Dixie Highway and the 33460/33463 neighborhoods west toward South Military Trail. Whether you’re in a 1957 CBS bungalow off West Lantana Road with original jalousie windows, or a 1980s stucco tract near Boynton Beach Boulevard with oxidized aluminum sliders, we’ve measured and quoted the opening type. The salt-laden southeast breeze off Lake Worth Lagoon hits every property east of Federal Highway harder than inland Boynton Beach or Greenacres - we account for that corrosion in our frame and hardware specs, not after the fact.
Why Sightline Windows & Doors Boynton Beach Is Lantana’s Preferred Impact Windows & Doors Company
Our Impact Windows & Doors team has completed measured surveys on more than 400 Lantana openings since 2012, from the original CBS ranch homes near Thurgood Marshall Elementary to the 1990s builds off Willoughby Road. Every one of those jobs started with a written price and finished with a documented photo record the homeowner received.
Lantana reviews consistently cite two things: our crews arrive in uniform with license numbers provided beforehand, and the invoice matches the quote. Haven Clause 3 (Verified Crews) means the technician at your door is the person on record - no subcontractor roulette.
Response time to Lantana runs same-week for measured surveys, with installation scheduling typically 10-14 days out once permits clear. Palm Beach County’s building department is familiar with our documentation package, which speeds the jalousie-to-impact conversion permits that dominate Lantana’s 33460 applications.
We know the local conditions: the ungrounded outlets in pre-1970s CBS walls, the failed sill flashing where block meets frame, the aluminum jamb tracks oxidized to powder by salt air. Generic quotes from out-of-area installers miss these. We don’t.
Our Impact Windows & Doors Services in Lantana

Hurricane Impact Windows
Lantana sits in a mandatory wind-speed design zone where every opening must be impact-rated or protected by approved shutters. Our hurricane impact windows are specified to HVHZ (High Velocity Hurricane Zone) standards, with laminated glass interlayers that stop wind-borne debris even if the outer lite fractures. For the 33460 bungalows near Louise E Buie Park, this typically means full-frame replacement of original single-pane aluminum sliders - the frames can’t accept impact glazing, and the rough openings often need treated blocking and re-flashing to pass inspection.

Horizontal Roller & Sliding Impact Windows
This is the workhorse replacement for Lantana’s original jalousie windows. Horizontal roller impact windows open sideways on a track, giving the wide sightlines that 1950s-1960s CBS homes were built for without the louvered-glass vulnerability. We spec PGT and CGI sliding systems with design pressure ratings matched to your exposure - lakefront properties on the Intracoastal see higher wind loads than sheltered interior lots. When the original CBS opening is undersized or out-of-square, we price the block modification in writing upfront, not as a change order.

Single Hung Impact Windows
Single hung impact windows, with a fixed upper sash and operable lower sash, fit Lantana’s smaller bedrooms and bathrooms where horizontal rollers would eat wall space. The 1980s-1990s stucco homes west of South Military Trail often have original single hung aluminum frames with failed balances and pitted tracks from salt oxidation. We measure the existing rough opening against the new impact frame’s dimensions - if the old frame was shimmed into place without proper blocking, we correct it and document the repair in the photo record.

Double Hung Impact Windows
Double hung impact windows allow both sashes to operate, which matters in Lantana’s older homes where cross-ventilation was the primary cooling before central air. For second-story additions and master bedroom renovations in the 33463 area, we specify double hung units with low-E insulated glass and warm-edge spacers. The U-factor and SHGC ratings are printed on the NFRC label we photograph for your file - evidence, not assurance.

Wind Mitigation & HVHZ Code Compliance
Every impact installation in Lantana triggers a permit and inspection under Palm Beach County’s wind-load requirements. We pull the permit, schedule the inspection, and provide the documentation your insurer needs for wind mitigation credits. The 365-Day Done Right Promise covers any inspector-flagged item - if the opening doesn’t pass, we make it right without additional charge.

AfterTrusted Brands We Service in Lantana
We specify from eight manufacturer lines, chosen by what the opening requires, not by warehouse inventory. For Lantana’s salt-air environment, we frequently recommend PGT’s aluminum impact frames with Kynar 500 finishes for corrosion resistance, or CGI’s vinyl systems where thermal performance is the priority. Therma-Tru entry doors with impact-rated fiberglass skins handle the humidity cycles without delamination. ViewLux provides the custom geometric shapes that 1950s ranch renovations sometimes need for clerestory or accent windows. We don’t stock every size - we measure, then order to spec, with lead times quoted in writing.
Common Impact Windows & Doors Problems We See in Lantana Homes

- Jalousie-to-impact conversions with undersized CBS rough openings. The 33460 corridor’s 1950s bungalows were built for louvered glass, not modern design pressure-rated frames. When we pull the original sash, we often find block openings too small or out-of-square for direct replacement. We price the modification - treated blocking, re-flashing, waterproofing - in the initial scope, not after demolition.
- Salt-air oxidation seizing aluminum frames and hardware. Properties east of Dixie Highway, especially lakefront homes catching the southeast breeze off Lake Worth Lagoon, show pitted tracks, frozen rollers, and corroded locks that turn a “replace the glass” call into full-frame replacement. We inspect the substrate before quoting; if the jamb is compromised, we say so.
- Permit-triggered electrical and framing surprises. Opening a 1960s CBS wall for impact window installation frequently exposes ungrounded outlets, undersized headers, or failed waterproofing at the sill. Our contracts include allowances for common corrections, and any surprise beyond those is priced and approved in writing before we proceed - Haven Clause 5 (No Surprises).
- Failed wind mitigation documentation from prior installations. We review Lantana homeowners’ existing wind mitigation reports and find openings that were replaced without proper permits, or shutters installed without Miami-Dade or Florida Product Approval numbers. We correct the documentation trail so the report holds up at renewal.

What moves the price: the condition of the existing frame and substrate, whether the CBS opening needs modification, the design pressure rating required for your exposure, and the glazing spec - clear, low-E, or low-E with argon. Every Lantana quote starts with a measured survey you keep; the written price cannot differ from that document. Bring us a competitor’s written estimate and we’ll review it at no charge - our Free Second Opinion.
On a 1957 CBS ranch off West Lantana Road near R C Kreusler Park, our crew pulled original jalousie sash and found the aluminum jamb tracks oxidized to powder, the rough opening undersized for a modern slider’s design pressure-rated frame, and the block needing re-flashing at the sill. We set new PGT impact-rated sliders with laminated glass interlayer and low-E glass, packed the CBS opening with treated blocking and proper waterproofing, and the homeowner’s wind mitigation report cleared every opening - while the permit-triggered inspection also caught two ungrounded outlets we resolved in writing before close-out.

FAQs - Impact Windows & Doors in Lantana

No. Jalousie windows cannot be made code-compliant under current Palm Beach County wind-load permitting, even with shutters. The louvered-glass design fails the large-missile impact test, and the frames lack the structural attachment points for approved shutter systems. Full replacement with impact-rated windows is mandatory. Call (561) 421-3844 for a measured survey and written quote - estimates are free.
Because 1950s-1960s CBS construction predates modern framing, waterproofing, and electrical standards. When we remove the original window, we frequently find failed sill flashing, undersized headers, or ungrounded circuits that must be corrected before the inspector will sign off. We build common corrections into our contract allowances, and anything beyond that is priced and approved in writing before we touch it - Haven Clause 5. Call (561) 421-3844 and we’ll review your specific opening.
Yes. The prevailing southeast sea breeze pushes salt-laden air across every Lantana property east of Dixie Highway, accelerating corrosion of aluminum frames, hardware, and fasteners far faster than inland locations. We’ve replaced aluminum slider tracks that were functional metal five years prior and crumbled to oxide dust when disturbed. We specify corrosion-resistant finishes and hardware for lakefront exposure, and we document the substrate condition in our initial survey. Call (561) 421-3844 for a free assessment.
Yes, if documented correctly. Florida insurers offer wind mitigation credits for impact-rated openings that meet HVHZ standards and are properly permitted and inspected. We provide the product approval numbers, permit documentation, and inspection sign-offs your agent needs. The credit varies by carrier and policy, but the documentation we deliver is what makes it real. Call (561) 421-3844 to schedule the survey that starts the process.
Most Lantana homeowners see 15-25% cooling cost reduction after replacing single-pane aluminum windows with low-E insulated impact units, depending on the home’s orientation, shading, and existing insulation. The SHGC (Solar Heat Gain Coefficient) rating we select for east- and west-facing openings in Lantana’s exposure is typically 0.25 or lower. We print the NFRC label values on your quote so you can calculate the payback yourself - no projected savings we can’t document. Call (561) 421-3844 for a free estimate with spec’d performance numbers.
Call (561) 421-3844 to schedule your free measured survey. You’ll receive a written price before any work starts, a documented photo record when the job is done, and the 365-Day Done Right Promise stamped on every opening - because the measurement and the quote are the same document, and they always have been.
