AfterCasement Windows in Lantana, FL
Casement windows in Lantana, FL typically run between $420 and $1,100 per window installed, depending on size, glazing type, and whether the opening requires impact-rated glass. Most single-window replacements are completed in one visit, with the written price handed to you before any work begins. At Sightline Windows & Doors, every casement project falls under the Haven Standard – the same documented process that has governed all 18,000+ openings we’ve installed since 2012.
If you’re replacing a single failed unit or re-glazing several windows across a Lantana home, the process starts the same way: a measured survey you keep, a written scope that cannot differ from that survey, and a crew that is background-checked and identified by license number before they arrive. Call us at (561) 461-2062 – a live person answers, not a voicemail queue – or read on to understand exactly what casement window installation in Lantana involves, what it costs, and what you receive in writing when it’s done, or explore our full Window Installation services.
Casement windows are a logical fit for a lot of Lantana homes, particularly the mid-century ranches and post-war cottages between Hypoluxo Road and West Ocean Avenue where single-hung units were the original spec. A casement swings outward on a side hinge, operated by a crank at the sill. That geometry does two things especially well in South Florida: it allows the full frame width to open for airflow – useful during the shoulder months when you want cross-ventilation without running the AC – and it seals more tightly than a sliding or hung window when latched against storm pressure. Our Window Installation in Lantana page covers the full scope of what we install; this page stays focused on casements specifically.
When You Need Casement Windows
- Your existing casement cranks but won’t seal. In Lantana’s salt-air environment, the zinc operators corrode faster than the frame. A window that swings open but leaves a visible gap at the weatherstrip when closed is no longer performing its primary job – wind-driven rain during a storm will find that gap immediately.
- You’re replacing single-pane glass in an older home. Pre-2000 Lantana homes near the Intracoastal frequently still have single-pane casements. U-factor readings on those units often exceed 1.0; modern impact-rated casements from CGI or CWS can deliver U-factors below 0.30, which is a measurable reduction in cooling load.
- Your insurance carrier has flagged non-impact openings. Palm Beach County has required impact-rated or protected openings on new construction since the early 2000s. Homeowners who purchased older Lantana properties sometimes discover at renewal that non-impact windows affect coverage terms. Impact-rated casements resolve that without boarding or shutters.
- You want more ventilation from a kitchen or bathroom window. A casement positioned over a sink or countertop opens fully with one crank turn – no sliding sash, no reaching past a storm screen. In Lantana’s humid summers, that difference in airflow matters for moisture control.
- You’re converting a fixed or jalousie opening. Jalousie windows are still found in older Lantana construction. Converting that rough opening to a modern casement frame requires a measured survey first – the rough-opening tolerances on jalousie frames don’t always match standard casement sizes – and that’s exactly the kind of detail our pre-install survey documents before pricing is set.
- A previous installation is leaking around the frame, not the glass. Frame-perimeter leaks usually trace to a bad seal at the nailing fin or improper flashing at the head. If the glass is intact but water is appearing at the sill or jamb, the issue is likely the installation, not the product – and our Free Second Opinion on Any Written Estimate applies here too.
Our Casement Windows Process
-
Measured Survey and Written Scope
Sonia Raman or one of our licensed technicians visits the Lantana address, measures every opening in question to the nearest eighth of an inch, and records the existing frame condition, glazing type, and any flashing or moisture concerns. That document – the measured survey – is yours to keep. The written price is built directly from it. There is no separate quote that arrives later with different numbers; Haven Clause 1 (Have It In Writing) means the measurement and the invoice are the same document.
-
Product Specification by Opening
We specify casements by what the opening requires, not by what is sitting in a warehouse, though we also offer Garden Windows and other styles for different needs. For Lantana homes in Palm Beach County’s wind-borne debris region, that usually means an impact-rated unit from CGI or CWS. For interior rooms where impact ratings are already covered by a protected opening, ES Windows offers casement lines with strong U-factor and SHGC numbers at a lower price point. Solar Heat Gain Coefficient – SHGC – is the fraction of solar energy that passes through the glass; in Lantana’s east-facing exposures, a lower SHGC is worth specifying even when it adds cost.
-
Crew Arrival and Identity Verification
Our technicians are background-checked, uniformed, and carry their license numbers with them – Haven Clause 3 (Verified Crews). You know who is at your door before the door opens. Arrival is scheduled to a window, not a vague half-day range, and we photograph the existing opening before a single tool touches it.
-
Removal and Opening Preparation
The existing casement sash and frame are removed, the rough opening is inspected for rot, moisture intrusion, or structural anomalies, and the sill and jambs are prepared for the new frame. In Lantana homes close to the Intracoastal, we regularly find frame-leg rot that wasn’t visible from the interior – documenting and addressing it before the new unit goes in is why the photo record exists.
-
Installation, Flashing, and Sealing
The new casement frame is set, shimmed to plumb and level, fastened to the rough opening per the manufacturer’s installation instructions and Palm Beach County building code, and flashed at the head and sill with self-adhering membrane. The crank hardware is tested through its full travel range, and the weatherstrip seal is verified at all four corners. Impact-rated units receive additional fastener schedules per the product’s Notice of Acceptance.
-
Documented Close-Out and 365-Day Promise
Before we leave, the completed opening is photographed – sill, head, jambs, interior and exterior – and those images are part of your job record. The 365-Day Done Right Promise is written into the Haven Standard on every job: if the installation is not right within the first year, we make it right. That is not a verbal assurance; it is documented on the same paperwork that carried the original price.
BeforeAfterCasement Windows Pricing in Lantana
Casement window installation in Lantana runs between $420 and $1,100 per window for most residential projects. The range is wide because casements vary significantly by size, glazing package, and whether Palm Beach County’s impact requirements apply to the opening. Below is a breakdown of the factors that move the number:
| Cost Factor | Typical Range | Notes |
|---|---|---|
| Standard casement unit (non-impact, single opening) | $420 – $620 | Interior or protected openings; ES Windows and ECO Window Systems typically specify here |
| Impact-rated casement unit (single opening) | $650 – $950 | Required for unprotected openings in Palm Beach County wind zone; CGI and CWS are common specs |
| Large or custom-sized casement | $850 – $1,100+ | Non-standard rough openings, oversized frames, or specialty glazing packages |
| Rough opening repair (rot, moisture damage) | $75 – $300 per opening | Priced and approved in writing before any repair begins – never added after the fact |
| Multi-window discount (5+ units, same visit) | Noted in written scope | Crew and travel efficiencies are passed through in the written price |
These are the numbers we see on actual Lantana jobs. They are not promotional estimates built to get a call – they are the kind of figures that appear on our measured survey documents. The written price you receive before work starts is the number on the invoice when work ends. No surprises is not a tagline here; it is Haven Clause 5.
If you have a written estimate from another contractor, our Free Second Opinion is available at no charge. Bring the document – we’ll review it line by line and tell you exactly where the numbers land relative to what we’d specify for the same opening.

What Makes Casement Windows Specific to Lantana Conditions
Lantana sits between the Intracoastal Waterway to the east and a series of canal-bordered subdivisions to the west. That geography means salt air, elevated humidity year-round, and wind exposure that varies meaningfully between a home on East Lantana Road and one four blocks west. Hardware corrosion on casement operators is faster here than in inland Palm Beach County zip codes – we see this consistently on homes near Lake Osborne and the South Lantana canal corridors. Specifying marine-grade hardware and corrosion-resistant sill extrusions is not optional on Lantana projects; it’s written into the product spec before pricing is finalized.
Palm Beach County’s wind-borne debris region designation also means that any unprotected opening – one not covered by a tested shutter or storm panel – requires impact-rated glazing to meet current code. Casements in that category need to carry a Florida Product Approval number and install per the product’s Notice of Acceptance, which specifies fastener type, spacing, and embedment depth. Our technicians work to those specs on every impact installation; the permit documentation travels with the job record.
The shoulder months – October through early December and March through May – are when Lantana homeowners tend to want casements open rather than relying on AC. Horizontal Roller Windows and casements that open to 90 degrees with a functioning crank and a tight weatherstrip seal perform differently from units that have been sitting uncranked for two years with oxidized hardware. If your existing casements are operable but sticky or improperly sealing, that’s worth a survey before committing to replacement – sometimes the operator can be serviced, and we’ll tell you that in writing if it’s the case.
Casement Windows and Your Lantana Home’s Energy Profile
Florida’s energy code uses U-factor and SHGC as the two primary glazing performance metrics. U-factor measures how much heat passes through the glass assembly; a lower number is better. SHGC is the solar heat gain coefficient – the fraction of solar radiation that enters the home as heat. In Lantana’s climate zone (ASHRAE 2A, hot-humid), the Florida Building Code currently sets maximum SHGC at 0.25 for east- and west-facing windows and maximum U-factor at 0.40 for residential replacements.
Impact-rated casements from CGI’s SH Series and CWS’s casement line both meet those thresholds, with some configurations coming in below 0.20 SHGC. That matters on Lantana homes where afternoon sun hits west-facing living room windows for four to six hours daily between June and September. The difference between a 0.25 SHGC and a 0.40 SHGC on a 36-by-48-inch casement or Picture & Fixed Windows is not trivial on a monthly FPL bill.
We specify by U-factor and SHGC values pulled from the product’s NFRC label, not from marketing literature. Those numbers go into the written scope so you can compare them directly if you’re getting multiple quotes.

FAQs – Casement Windows in Lantana, FL
How much does casement window installation cost in Lantana?
Casement window installation in Lantana runs $420 to $1,100 per window, with most single-unit replacements landing between $600 and $850 depending on impact-rated requirements and frame size. Rough opening repairs, if needed, are priced separately in writing before any work begins. Call (561) 461-2062 for a written price specific to your opening – estimates are free and the measurement visit costs nothing.
Do casement windows in Lantana need to be impact-rated?
Yes, if the opening is unprotected. Palm Beach County requires impact-rated glazing or an approved protection system – tested shutters or storm panels – on all exterior openings in the wind-borne debris region. Most Lantana homes fall within that designation. A casement without impact glass that lacks a tested storm panel does not meet current Florida Building Code for that opening. We confirm the requirement at the measured survey and specify accordingly.
How long does casement window replacement take in Lantana?
A single casement replacement typically takes two to four hours, start to finish, including removal, rough-opening inspection, installation, flashing, hardware testing, and close-out photography. Replacing three to five units in one home is usually a full-day visit. Lead time from signed scope to scheduled install has recently run two to four weeks for most product lines, though CWS and ES Windows orders can sometimes be tighter depending on current stock.
Can you replace a jalousie window with a casement in Lantana?
Yes. Jalousie-to-casement conversions are common in older Lantana construction, particularly in the neighborhoods south of Hypoluxo Road. The rough opening usually needs to be reframed to accept a standard casement unit because jalousie frames were built to different tolerances. That reframing is scoped and priced in writing before work starts – it’s not a surprise line on the invoice. The measured survey documents the existing condition so the written price reflects the actual work required.
What casement window brands does Sightline install in Lantana?
We draw from eight manufacturer lines and specify by what the opening requires. For Lantana impact projects, we most frequently work with CGI and CWS casement products, both of which carry Florida Product Approvals covering Palm Beach County’s wind zone. For non-impact or interior protected openings, ES Windows and ECO Window Systems offer solid performance at a lower price point. The product selection goes into the written scope so you can review it before committing.
