How Much Does Impact Window Installation Cost in Lantana?
Impact window installation in Lantana, FL typically costs between $850 and $2,400 per window, installed, depending on size, glass type, and frame material. A whole-home project on a standard Lantana single-family house – usually 8 to 14 openings – runs $9,500 to $28,000 before any utility rebates or insurance discounts are applied. At Sightline Windows & Doors, every project starts with a written price tied to a measured survey; the number you see before work starts is the number on your final invoice.
Impact Window Installation Cost Breakdown (2026)
Impact window installation in Lantana costs break down across four main variables: the window unit itself, the glazing package, installation labor, and permit fees. Here is what each line item looks like in the current Lantana market.
| Line Item | Low End | High End | Notes |
|---|---|---|---|
| Single-hung impact window (small, up to 36″x48″) | $420 | $750 | Unit cost only; ES Windows, ECO Window Systems entry lines |
| Single-hung impact window (large, 48″x72″ and up) | $750 | $1,400 | PGT WinGuard, CGI Guardian lines |
| Casement impact window | $600 | $1,600 | CWS, ECO, or PGT depending on sightline width |
| Fixed/picture impact window | $380 | $900 | No moving parts; lowest per-unit labor |
| Impact sliding glass door (6 ft) | $1,800 | $3,400 | PGT, CGI, or CWS; separate from window count |
| Installation labor per window | $120 | $320 | Varies by frame condition, opening type, floor level |
| Palm Beach County permit fee | $75 | $250 | Per opening; Lantana Building Division schedules required inspections |
| Buck or sub-sill repair (if needed) | $80 | $300 | Common in Lantana homes built before 1990 near the Intracoastal |
| Stucco/drywall patch after installation | $60 | $180 per window | Required when retrofit opening is resized |
| Whole-home project (8-14 windows, typical Lantana SFR) | $9,500 | $28,000 | Includes product, labor, permit, basic trim |
The widest cost swings in Lantana projects come from two things: glass specification and frame condition. Homes within a few blocks of the Intracoastal Waterway – think the streets between South Dixie Highway and the water in Lantana’s eastern residential pockets – often arrive with corroded aluminum frames that need full buck replacement rather than a simple retrofit. That adds $150 to $300 per opening and is something we document in the measured survey before a dollar amount is committed. Glass specification matters just as much: a standard laminated impact unit rated at 140 mph wind load costs noticeably less than a high-performance low-E laminated unit with a solar heat gain coefficient (SHGC) below 0.25, which is worth considering given Lantana’s summer cooling loads. The difference can be $80 to $200 per window in product cost alone, and over ten years that gap is often recaptured in FPL bill savings.
What Affects Impact Window Installation Pricing in Lantana

Six factors consistently move the number up or down on Lantana projects. None of them are surprises – they show up in the measured survey before the quote is written.
- Window size and opening count: Larger glazed areas require heavier laminated glass and more labor to maneuver safely. In Lantana’s mid-century CBS homes – common between Lake Worth Road and 6th Avenue South – standard bedroom windows run 36×48 inches, while living room picture windows can reach 72×60 or wider. Each step up in size adds product and labor cost.
- Glass package and performance specification: Florida Building Code Section 1609 requires a minimum design pressure (DP) rating for coastal Palm Beach County, but the specific DP rating your home needs is determined by its exposure category, not a flat number. Entry-level impact glass meets code; a premium low-E unit with a U-factor of 0.29 or lower will cost more upfront and save more in cooling costs over time. We specify by what the opening requires.
- Frame material – aluminum vs. vinyl: Aluminum frames dominate Lantana’s older housing stock and hold up well in the salt air off the Intracoastal, but they transmit more heat. Vinyl frames offer better thermal performance at lower cost, though they’re less common in CBS construction. The frame choice shifts per-unit cost by $60 to $200 depending on the opening size.
- Existing frame and rough opening condition: Lantana homes built in the 1960s and 1970s along Hypoluxo Road and east of Federal Highway frequently show galvanic corrosion in aluminum frames and wood rot in sub-sills. When the rough opening needs repair before a new unit can be set, that’s documented in the measured survey with a line-item cost – no surprises later.
- Floor level and site access: Single-story installations in Lantana are straightforward. Second-floor work – particularly on the two-story construction that has gone up near Mango Road and in newer in-fill developments – adds staging time and labor. Expect $40 to $80 per window in added labor for second-floor openings.
- Permit and inspection requirements: Palm Beach County and the Lantana Building Division require permits for impact window replacement, and the inspection schedule affects project timeline. We handle permit filing as part of every Sightline project; the permit fee is a pass-through cost, never marked up, and it appears as its own line on the written price document.

AfterImpact Window Brands We Install in Lantana – and What They Cost
Sightline specifies from eight manufacturer lines. The choice isn’t driven by what’s in the warehouse; it’s driven by the opening’s performance requirements and the customer’s documented budget. Here’s how those lines map to price in the Lantana market.
Entry to Mid-Range: ES Windows and ECO Window Systems
Both ES Windows and ECO Window Systems produce Florida-code-compliant impact product at a price point that makes whole-home projects financially feasible without stretching. For a standard Lantana single-family home with 10 openings, an ES Windows or ECO specification typically lands the installed project in the $11,000 to $16,000 range. These aren’t cut-rate units – they carry the required Notice of Acceptance (NOA) approvals for Palm Beach County – but they’re optimized for cost-per-opening rather than maximum thermal performance.
Mid-Range with Higher Thermal Performance: CWS and Mr-Glass
CWS and Mr-Glass product lines step up in frame engineering and glass options, bringing better U-factor and SHGC ratings into reach at a price roughly 15 to 25 percent above the entry lines. For a 10-window project in Lantana, expect an installed range of $14,000 to $20,000 depending on configuration.
High-Performance: PGT WinGuard and CGI Guardian
PGT and CGI are the most recognized names in Florida impact glazing, and their performance specifications back that reputation. PGT’s WinGuard aluminum line and CGI’s Guardian series carry high DP ratings and premium low-E glass options that perform well in Lantana’s exposure category. For a 10-window whole-home project specified to PGT or CGI, the installed range typically runs $18,000 to $26,000. The difference over an entry-level spec shows up in air infiltration readings, long-term seal integrity, and acoustic performance – measurable things, not marketing claims.
Specialty and Custom: ViewLux and Therma-Tru
ViewLux handles specialty shapes and custom geometry – arched windows, trapezoids, and the round or elliptical accents that appear in some of Lantana’s newer custom construction near the water. Therma-Tru covers impact-rated door systems where the entry point needs to match the window specification. Both carry premium pricing tied to custom fabrication; project costs for these units are quoted per-opening after the measured survey, not from a price sheet.
Palm Beach County Permit Requirements for Lantana Impact Windows

Every impact window replacement in Lantana requires a permit through Palm Beach County’s Building Division, and the Lantana Building Department coordinates the inspection schedule. This isn’t optional and it isn’t a bureaucratic inconvenience – the permit record is what ties the installed window’s Notice of Acceptance (NOA) to your home’s address, which is the document your insurance carrier and any future buyer will ask for. We file the permit as part of every project. The fee is passed through at cost, itemized on the written price document, and the permit number is included in the photo record we leave with you at job completion. If a contractor quotes you impact windows without mentioning a permit, that is a red flag worth taking seriously.
Palm Beach County also requires that impact windows meet or exceed the design pressure (DP) rating for the applicable wind speed zone. Lantana sits in the 170 mph ultimate design wind speed zone under ASCE 7-22, and the Florida Building Code 2023 edition governs. The specific DP rating required for each opening depends on the opening size, distance from corners, and floor level – all of which show up in the measured survey we complete before quoting.
How to Save on Impact Window Installation in Lantana
There are real ways to reduce the total cost of an impact window project in Lantana without cutting corners on product or installation quality. Here are the ones that actually move the number.
- Request a Citizens Insurance discount letter before you finalize your product spec. Citizens Property Insurance offers meaningful premium reductions for homes with full impact protection, and the exact percentage depends on your current coverage and home construction type. Some Lantana homeowners see annual savings of $800 to $2,000 or more – enough to meaningfully affect payback period calculations. Get the discount estimate in writing from Citizens before committing to a product tier, so you can factor it into the comparison.
- Ask about FPL’s energy efficiency rebate programs. Florida Power & Light periodically offers rebates for qualifying energy-efficient windows. The rebate amounts and qualifying U-factor thresholds change; call FPL or check their current program terms before your project starts. This is a real dollar offset, not a marketing add-on.
- Do the whole home at once rather than phasing by room. On a 12-window home in Lantana, splitting the project into two phases of six windows typically costs $600 to $1,200 more in total – two permit filings, two mobilizations, and two inspection cycles. If the budget allows, a single whole-home project is almost always the lower-cost path per window.
- Get a second opinion on any written estimate. Sightline offers a free second opinion on any written estimate from another contractor. Bring us the document – not the verbal summary, the written quote – and we will review it line by line. If the number is fair, we’ll say so. If there are gaps in scope or inflated line items, we’ll show you exactly where. Call (561) 461-2062 to set that up; there’s no charge and no obligation.
- Match the glass spec to the opening’s actual requirements. Not every window in your Lantana home needs the highest-specification low-E glass. A north-facing bedroom window that receives little direct sun has a different cost-benefit profile than a west-facing living room window that takes afternoon heat load for six months a year. We specify by opening, not by blanket package, which can reduce total project cost by 8 to 12 percent without compromising code compliance or storm protection.
- Verify the permit is included in the quote. Some Lantana contractors quote window installation without the permit, then add it as a change order after the contract is signed. The Sightline written price always includes the permit fee as a line item. If a competitor’s quote doesn’t show the permit cost, add $75 to $250 per opening to the comparison before deciding.
What the Sightline Written Price Document Includes

Haven Clause 1 – Have It In Writing – means the measured survey and the written quote are the same document. When Sonia Raman’s team completes a measured survey at your Lantana home, you receive a document that lists every opening by location, the specified product by manufacturer and model, the installed unit price, labor, permit fee, and any identified rough-opening repair as separate line items. That document doesn’t change when the crew arrives. The final invoice is generated from the same document.
The photo record is standard on every job, not an upsell. Before and after photos are documented by opening and kept on file – useful for insurance claims, permit records, and the 365-Day Done Right Promise. If anything isn’t right within 365 days of installation, that promise is written into the Haven Standard, not offered as a verbal courtesy. Sightline has applied it to every one of the 18,000+ openings completed since 2012.
Every technician who arrives at your Lantana address is background-checked, uniformed, and identified by license number before the visit – Haven Clause 3, Verified Crews. The person on the job is the person on the record.

Comparing Impact Windows to Hurricane Shutters: A Cost Note
A question we hear regularly in Lantana: “Are impact windows worth it compared to accordion shutters?” The installed cost of accordion shutters for a typical Lantana home runs $4,500 to $9,000 – considerably less than a full impact window replacement. But the comparison isn’t straightforward. Shutters require deployment before each storm, don’t improve thermal performance, don’t reduce noise, and don’t carry the same insurance discount as fully glazed impact openings in some Citizens policy structures. Impact windows also eliminate the storage and maintenance burden of shutter panels. The right answer depends on the home, the homeowner’s use pattern, and the insurance structure – and it should show up as a documented comparison, not a sales pitch. We’ll show you both numbers.
FAQs – Impact Window Installation Cost in Lantana

How much does it cost to replace all windows with impact windows in a Lantana home?
A full impact window replacement for a typical Lantana single-family home with 8 to 14 openings costs $9,500 to $28,000 installed, including product, labor, and Palm Beach County permit fees. The lower end reflects entry-line product (ES Windows, ECO Window Systems) in good-condition openings; the upper end reflects premium PGT or CGI product in larger openings or homes with frame repair needs. Call (561) 461-2062 for a written price tied to your specific home – estimates are free and the number doesn’t change when the crew arrives.
Is impact window installation in Lantana cheaper than in other Palm Beach County cities?
Labor rates across Palm Beach County are broadly similar, so the installed cost in Lantana is within 3 to 5 percent of what you’d see in Lake Worth Beach, Boynton Beach, or Manalapan for the same product specification. Where Lantana can differ is in frame condition: homes close to the Intracoastal in the eastern part of town often need more rough-opening prep work due to salt-air corrosion, which adds cost compared to inland locations. A measured survey is the only reliable way to know what your specific address will run.
How long does impact window installation take in Lantana?
Most whole-home impact window projects in Lantana take 1 to 3 days on-site once product arrives. Product lead times from manufacturers like PGT, CGI, and CWS currently run 4 to 10 weeks from order confirmation in the 2026 market. The Palm Beach County permit and inspection schedule adds roughly 1 to 2 weeks to the timeline on each side. We give you a project schedule in writing at the time of the quote so you know the sequence before committing.
Do impact windows in Lantana qualify for insurance discounts?
Yes. Full impact window protection – meaning every glazed opening in the home, including doors and skylights – typically qualifies for a wind mitigation credit under Citizens Property Insurance and most private carriers operating in Palm Beach County. The credit amount varies by policy and home construction type; Lantana homeowners with wood-frame or CBS construction and full impact protection have reported annual premium reductions ranging from several hundred dollars to over $2,000. You’ll need a wind mitigation inspection report after installation to submit to your carrier; the permit record and NOA documentation we provide as part of every project support that inspection.
What is the cheapest impact window option for a Lantana home that still meets code?
The lowest-cost Florida-Building-Code-compliant impact window available from Sightline’s product lines starts in the $420 to $600 range per unit for smaller openings, specified from ES Windows or ECO Window Systems. Installed with labor and permit, a small to mid-size opening in good condition runs approximately $650 to $950 all-in. These units carry the required Notice of Acceptance (NOA) approvals for Palm Beach County and meet the wind load requirements for Lantana’s coastal zone. They don’t carry the thermal performance specs of PGT or CGI premium lines, but they’re code-compliant and storm-rated. Call (561) 461-2062 for a written quote by opening – we’ll tell you exactly what each one costs before anything is ordered.
