How Much Does Window Replacement Cost in Lantana?

Window replacement in Lantana, FL typically costs between $380 and $1,200 per window installed, with most single-family homes in town paying $6,500 to $18,000 for a full-house project. Impact-rated windows – required by Palm Beach County code for new installations in wind-borne debris regions – sit at the higher end of that range, generally $650 to $1,400 per opening depending on size, glass package, and frame material.

Those numbers include labor, the measured survey, and the written scope Sightline Windows & Doors hands you before any work begins. They do not include permit fees, which Palm Beach County currently charges separately and vary by project value.

Window Replacement Cost Breakdown (2026)

The table below reflects what Sightline sees in the Lantana market on actual jobs, not a national average carried in from a spreadsheet. Prices assume standard residential openings, impact-rated glazing (the practical standard here given county wind maps), and full installation including haul-away of the old unit.

What Moves the Price Up or Down

The single biggest variable in Lantana is glass specification. Palm Beach County sits in a High-Velocity Hurricane Zone (HVHZ) – the same designation that covers Miami-Dade – which means the county enforces some of the strictest glazing standards in the country. Any window installed as a replacement in a permitted scope must meet Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval (FPA) standards. That narrows the product field and keeps base prices above what you might see quoted in, say, a non-coastal county.

Frame material is the second lever. PGT and CGI aluminum frames – both of which Sightline carries – are standard in Lantana’s coastal climate because aluminum holds up against the salt air that rolls in off Lake Worth Lagoon without the swelling and moisture intrusion that wood frames develop within a few years this close to water. Vinyl performs well in protected inland areas but can soften under sustained direct sun on south- and west-facing elevations, which is worth factoring in for homes south of Hypoluxo Road with unshaded rear exposures.

Labor complexity adds cost when stucco surrounds need to be cut and patched, when a frame is not square, or when the rough opening requires modification to accept a different unit size. On older CBS (concrete block and stucco) homes in west Lantana, this is common – the original openings were built for jalousie or single-pane aluminum windows that are narrower than today’s standard impact units, and the stucco work alone can add $80 to $200 per opening.

What Affects Window Replacement Pricing in Lantana

• Impact vs. non-impact glass: In Lantana’s wind-borne debris region, permitted replacements require impact-rated or protected glazing. Impact glass adds roughly $120 to $280 per window over standard double-pane, but it also eliminates the need for accordion shutters on most openings – which changes the real cost comparison significantly.
• Frame material and corrosion resistance: Aluminum frames with a Kynar or powder-coat finish hold up best within a mile of the coast. Homes east of Federal Highway, particularly those on or near the Intracoastal, should specify marine-grade finishes. That’s a real line item, not an upsell.
• Window size and configuration: Lantana’s housing stock is diverse – everything from compact 1950s cinder-block cottages near the beach to larger 1990s-built homes in developments west of Military Trail. A house with fourteen 24×36 single-hungs costs meaningfully less than one with eight oversized picture windows and two arched transoms.
• U-factor and SHGC ratings: Florida’s energy code (Florida Building Code 8th Edition) requires replacement windows to meet minimum solar heat gain coefficient (SHGC) and U-factor thresholds. Low-E coatings that hit those thresholds add to glass cost but reduce cooling load – meaningful in Lantana, where air conditioning runs ten months of the year. CWS and ES Windows offer several glass packages that exceed code minimums without pushing into premium pricing.
• Permit and inspection fees: Palm Beach County charges a permit fee scaled to project value, plus a separate inspection fee. On a mid-size full-house project valued around $12,000, expect to budget $180 to $380 for the permit itself. Sightline pulls the permit as part of the written scope – it’s not added as a surprise line after the quote is signed.
• Stucco and finish work: CBS construction is the norm in Lantana, and any time a frame is removed from a stucco surround, the opening needs to be patched and painted to match. On a full-house project, this can add $400 to $1,200 depending on the number of openings and whether the original stucco finish is a standard sand texture or a custom pattern that needs to be matched.

Impact Windows in Lantana: Why They’re the Practical Standard

If you’re getting replacement windows in Lantana, the conversation about whether to go impact-rated is largely settled by geography. The town sits east of I-95 and within Palm Beach County’s HVHZ designation. For a permitted replacement scope, impact-rated windows are the path of least resistance through the inspection process. Non-impact windows can be installed in HVHZ areas if paired with an approved protection system (accordion shutters, panel shutters), but the combined cost of non-impact windows plus shutter hardware usually exceeds the cost of impact glass by itself – and impact glass leaves every opening unobstructed day to day.

Sightline installs impact windows from PGT, CGI, and ECO Window Systems. Each of those lines carries Miami-Dade NOA approvals. The product is specified to the opening, not to what happens to be in the warehouse – which is what Haven Clause 1 (Have it in writing) means in practice: the product, the approval number, and the installed price are all on the document before work starts.

For a deeper look at the full scope of what a replacement project involves in this market, our Window Replacement in Lantana page walks through the process from measured survey to photo-documented close-out.

Energy Efficiency and What It’s Actually Worth in Lantana

Lantana’s climate is almost entirely cooling-dominated. The heating load from November through February is minimal, and the real energy performance question is how much solar heat a window lets in during the other ten months. The metric is SHGC – solar heat gain coefficient – expressed as a number between 0 and 1. Lower is better for a south-facing wall in South Florida.

Florida’s energy code requires replacement windows in climate zone 1 (which includes all of Palm Beach County) to meet an SHGC of 0.25 or lower for glazed areas. Many of the impact glass packages from PGT’s WinGuard line and CGI’s Series 100 and 150 meet or beat that threshold. A window at SHGC 0.22 versus one at SHGC 0.30 can reduce cooling load enough to lower an average Lantana home’s FPL bill by $15 to $40 per month, depending on house size and orientation – that’s a real return, not a marketing number, and it comes back to you every month for the life of the window.

U-factor governs how much heat moves through the window regardless of sun angle. In Lantana, this matters less than SHGC, but code still requires a U-factor of 0.50 or lower on replacement windows. Most impact glass packages from the lines Sightline carries are at 0.29 to 0.40, well within compliance.

How to Save on Window Replacement in Lantana

The most direct way to control cost is to get the scope right before anyone orders glass. Custom and semi-custom units that have to be remade because of a measurement error are expensive, and they push your project back by six to ten weeks. That’s not a hypothetical – it’s a recurring pattern in this market when installers separate the “sales measurement” from the “install measurement.” Sightline’s measured survey is the final measurement. There’s one document, one number, and it doesn’t change.

Beyond that, here are the strategies that actually move the number:

• Bundle the project: Replacing eight or more windows in a single permitted scope nearly always yields a lower per-unit cost than replacing two windows today and six next year. Volume allows for a single permit pull, a single stucco patch scope, and manufacturer pricing at quantity thresholds. On a full-house project, the per-unit savings over piecemeal replacement runs $40 to $120 per window depending on the product line.
• Match the product to the opening, not to the upsell: A picture window on an interior wall doesn’t need a marine-grade aluminum finish. A casement facing west in full sun does. Over-specifying in some areas to under-specify in others wastes money in both directions. The written scope should name the product, the finish, and the reason for each.
• Get a second opinion on any existing quote: Sightline offers a free second opinion on any written estimate. Bring in a competitor’s quote and we’ll review it – line by line, product specification by specification. This is not a loss-leader tactic; it’s how Haven Clause 1 works in practice. If a quote doesn’t name the product, the NOA number, and the installed price, it’s not a real quote yet.
• Ask about FPL rebates and federal tax credits: The Inflation Reduction Act’s energy efficiency provisions allow a federal tax credit of up to 30% on qualifying energy-efficient windows (windows meeting ENERGY STAR Most Efficient criteria), capped at $600 per year. FPL periodically runs rebate programs on qualifying products. These aren’t guaranteed, and they change – but they’re worth confirming at estimate time with your tax adviser.
• Time the permit correctly: Palm Beach County building permits have expiration timelines. Starting a permit and then delaying the work past the inspection window can require a re-permit, which adds cost and time. Make sure the installation schedule is confirmed before the permit is pulled.

Manufacturer Lines and What They Cost in the Lantana Market

Sightline specifies from eight manufacturer lines, and the choice of line is driven by what the opening requires, not by margin. Here’s how those lines map to the Lantana market and typical installed price ranges:

• PGT WinGuard (impact): The workhorse of South Florida residential impact replacement. Aluminum and vinyl frame options. Installed cost typically $480 to $920 per standard opening. Strong HVHZ product library.
• CGI Series 100 / Series 150 (impact): Engineered specifically for Florida’s coastal environment. Aluminum frames with heavy-wall extrusions. Installed cost $520 to $1,050 per opening. CGI’s laminate glass options perform well in the salt air east of Federal Highway.
• CWS (impact and non-impact): Florida-made product with a strong presence in Palm Beach County. Good mid-range price point for inland applications where a full marine-grade spec isn’t required. Installed cost $420 to $800 per standard opening.
• ES Windows (impact): Aluminum-framed, HVHZ-approved. Positioned slightly below CGI on cost while maintaining full impact compliance. Installed cost $400 to $750 per standard opening.
• ECO Window Systems (impact): Florida-manufactured with a strong installer network in Palm Beach County. Competitive on commercial and multi-unit residential specs. Installed cost $440 to $820 per opening in residential applications.
• ViewLux (custom and architectural): Used where standard product lines can’t accommodate the opening geometry – arched transoms, large picture windows, geometric shapes. Pricing is project-specific, generally $950 to $2,400+ per opening.
• Mr-Glass: Specified for select glazing and custom applications. Pricing varies by scope.
• Therma-Tru: Sightline’s door line – not a window product, but relevant if the project includes an entry door replacement alongside windows.

The Permit Process for Window Replacement in Lantana

Palm Beach County building permits are required for window replacements in Lantana. This is not optional, and unpermitted window work creates real problems at resale – a disclosure requirement, a potential stop-work order if discovered, and the cost of re-doing the work correctly under permit. Sightline pulls the permit as part of the written scope, and the permit number and inspection schedule are part of the documentation the customer receives.

The inspection sequence for a typical replacement project in Palm Beach County involves a rough-in inspection (frame set, before stucco is closed) and a final inspection. The inspector confirms the product approval number on the label against the approved Florida Product Approval or Miami-Dade NOA in the permit application. If those numbers don’t match, the job doesn’t pass. That’s the reason the product specification in the written scope matters – it’s not a formality, it’s the document that gets checked at inspection.

Permit turnaround in Palm Beach County currently runs 10 to 21 business days for standard residential window replacements, depending on the county’s review queue. Projects submitted through the county’s electronic permitting portal (EnerGov) typically move faster than paper submissions. Factor this into the project timeline: once the permit is in review, the window order can be placed, but installation can’t begin until the permit is issued.

What the Sightline Process Looks Like in Lantana

Every project starts with a measured survey. A background-checked, uniformed technician arrives at the scheduled time, measures every opening to be replaced, notes the frame condition, the substrate (CBS block vs. wood frame), the stucco profile, and the existing product. That survey becomes the written scope – and the written scope becomes the final invoice. Those are the same document. That’s not a slogan; it’s Haven Clause 1.

The customer keeps a copy of the measured survey. When the job is done, a documented photo record covers every opening – before and after, including product labels showing the NOA or FPA number. That photo record is the customer’s evidence file, not Sightline’s marketing material.

Every completed job is covered by the 365-Day Done Right Promise. If anything about the installation isn’t right within a year of completion, Sightline makes it right. That’s written into the Haven Standard, not offered as a courtesy.

Sonia Raman, who leads Sightline Windows & Doors, has structured every part of the process around one principle: the customer should know the price, the product, and the standard before a single tool is lifted. In over 18,000 openings installed since 2012, that hasn’t changed.

FAQs – Window Replacement Cost in Lantana, FL

How much does it cost to replace a single window in Lantana?

A single impact-rated window replacement in Lantana typically costs $380 to $950 installed, depending on size, frame material, and glass specification. Standard single-hung and slider units in a typical ranch home sit at the lower end of that range; larger double-hung or casement units with upgraded glass packages run higher. Call (561) 461-2062 for a written estimate – it’s free, and you’ll have an exact number before any work is scheduled.

Is it cheaper to replace all windows at once or a few at a time?

Replacing all windows in a single permitted scope costs less per window than replacing them in stages. The savings come from a single permit pull, single mobilization, and manufacturer volume pricing. In the Lantana market, the difference runs $40 to $120 per window less when eight or more units are done together versus two or three at a time. If budget is the constraint, a phased approach can work – but it’s worth knowing what the full-project price looks like before deciding.

Do I need impact windows in Lantana?

For a permitted replacement, yes – in practice. Lantana falls within Palm Beach County’s wind-borne debris region, and the county enforces HVHZ standards for new and replacement glazing. Non-impact windows can be installed if paired with an approved protection system, but the combined cost of non-impact glass plus shutter hardware usually meets or exceeds the cost of impact-rated windows alone. Most homeowners in Lantana replacing windows under permit go impact-rated. Call (561) 461-2062 if you want to talk through the options for your specific opening configuration.

What is the typical timeline for window replacement in Lantana?

From signed scope to installed windows, most standard replacement projects in Lantana run 4 to 8 weeks. That timeline breaks down as roughly 10 to 21 business days for Palm Beach County permit approval, 2 to 5 weeks for product fabrication and delivery (impact windows are built to order, not pulled from a shelf), and 1 to 3 days for installation depending on the number of openings. Projects requiring custom or geometric units from ViewLux run longer – 8 to 12 weeks is realistic for those.

Does window replacement add value to a Lantana home?

Impact window replacement in Lantana typically recovers 70% to 85% of its installed cost in resale value, based on Palm Beach County market patterns – and that’s before accounting for the insurance premium reductions many carriers offer when a home has full opening protection. Buyers in Lantana actively look for impact protection as a line item, and homes without it often draw lower offers or requests for price concessions. The documentation Sightline provides – the permit, the photo record, the product approval numbers – travels with the home and is the kind of evidence a buyer’s inspector and insurance underwriter actually want to see.
