AfterTrusted Custom & Geometric Windows for Lantana Homeowners
Custom and geometric windows in Lantana typically run $1,200-$4,500 per opening depending on shape complexity, glazing specification, and whether impact rating is required. Most measured surveys are scheduled within 48 hours, and the written quote you receive is the same document our crew works from on installation day. Call (561) 461-2062 to book your measured survey.
We’ve installed 18,000+ windows and doors since 2012, every one with a written price before work started and a documented photo record when finished. In Lantana, we regularly see custom window needs in the historic homes near K Street and the newer construction east of I-95 where standard rectangular units don’t match the architectural intent, similar to the Lake Worth Custom & Geometric Windows projects we’ve completed. The salt air and hurricane exposure here mean geometric shapes can’t just look right; they have to perform under pressure. Our measured survey captures frame readings, sightline measurements, and product specs so the quote and the installation match exactly.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows are built to your exact dimensional and shape specifications while meeting Florida Product Approval for high-velocity hurricane zones. You need these when your opening is non-standard and your home is within the wind-borne debris region, which covers all of Palm Beach County including Lantana. At Sightline Windows & Doors Lantana, we specify custom impact units from PGT and CGI with laminated glass interlayers rated for the 170 mph design pressures common in coastal Palm Beach County; the measured survey documents the exact frame depth, jamb condition, and anchor pattern before any order is placed.
Geometric & Shaped Windows
Geometric and shaped windows include triangles, trapezoids, pentagons, and other non-rectangular configurations that complement gable ends, stairwells, and accent walls. These are specified when the architecture calls for visual interest that standard units can’t provide, particularly in the ranch-style homes and mid-century builds common in Lantana’s older neighborhoods. We measure every angle with digital protractors and transfer those readings directly to our fabrication orders for CWS and ES Windows lines; the customer keeps the measured survey, and the written quote references those exact dimensions so there’s no reinterpretation at installation.
Arched & Curved Windows
Arched and curved windows feature radius tops or full circular configurations that soften exterior elevations and bring directional light into entryways and great rooms. These become necessary when replacing original architectural windows in Mediterranean-influenced homes or when matching historical profiles in Lantana’s established neighborhoods near the Intracoastal. Our crew templates curved openings on-site with flexible measuring strips, then sends those templates to the manufacturer for CNC cutting; the documented photo record shows the template match before fabrication begins, so the unit that arrives fits the opening that exists, not the one drawn on plans.
Oversized Openings
Oversized openings exceed standard manufacturer dimensions and require engineered solutions for structural support, glazing weight, and hardware operation. These arise in modern construction, additions, and wall removals where the goal is uninterrupted glass and maximum light, common in the renovated homes we’re seeing in Lantana’s waterfront areas. We specify reinforced frames from ECO Window Systems and ViewLux with steel reinforcements and multi-point locking hardware; the measured survey includes load calculations and header condition assessments that become part of the written scope you approve before any work starts.

Brands We Service for Custom & Geometric Windows
We work with eight manufacturer lines, specified by what the opening requires, not by what is in stock. For custom and geometric work in Lantana, we regularly specify CGI for impact-rated architectural shapes with narrow sightlines and clean profiles that suit modern and transitional homes. Their custom program accepts radius, polygon, and combination shapes with laminated impact glass, and we’ve templated hundreds of their units across Palm Beach County. CWS offers competitive lead times on geometric vinyl frames with Kevlar-reinforced corners, a specification we use frequently in Lantana’s salt-air environment where corrosion resistance matters as much as wind resistance.
ES Windows fabricates large-format custom impact units up to 120 inches in some configurations, which we specify for oversized openings where standard maximums don’t suffice. ECO Window Systems provides thermally broken aluminum custom shapes with U-factors as low as 0.30, suitable for energy-conscious builds in Lantana where the cooling load runs high eight months of the year. Whether you have CGI, CWS, ES Windows, ECO Window Systems, or any other make, we can template, specify, and install it. Our free second opinion on any written estimate applies to custom work too; bring us a competitor’s quote and we’ll review the specifications at no charge.
BeforeAfterSigns You Need Custom & Geometric Windows Right Now
- Your existing shaped window shows seal failure or condensation between panes. Geometric and arched units often use fixed glass without operable sashes, so seal failure is the primary failure mode. Once the insulated glass unit fogs, the thermal performance is gone and the view is obstructed; in Lantana’s humidity, this worsens quickly and can lead to frame deterioration if moisture weeps into the surrounding structure.
- You’re remodeling and the new opening doesn’t match standard dimensions. Wall removals, additions, and reconfigurations frequently create openings that no stock window fills properly. A custom unit measured to the actual rough opening eliminates the shimming, trimming, and sealing compromises that come from forcing a standard size into a non-standard hole.
- Your home’s architecture depends on specific shapes that are now discontinued. Many Lantana homes built between 1960 and 1990 used radius-top and octagonal windows from manufacturers no longer operating. We can replicate those profiles from current product lines or fabricate to template, maintaining the exterior character while upgrading to modern impact and energy performance.
- You need impact rating but can’t accept the bulk of standard impact frames. Standard impact windows often carry deeper frames and thicker sightlines that overwhelm delicate architectural shapes. Custom impact programs from CGI and PGT offer slimmer profiles engineered specifically for geometric applications where appearance and code compliance both matter.
- You’re finishing a room with an odd-shaped gable or dormer and need daylight without sacrificing wall performance. Triangular and trapezoidal windows in attic conversions and vaulted spaces require precise angle matching and proper flashing integration. A templated custom unit with integrated nail fins seals against the roof plane correctly, where a site-built solution invites leaks and voids manufacturer warranties.
Our Custom & Geometric Windows Process - Step by Step
- 1
Measured survey and documentation. Our technician arrives with digital calipers, laser measures, and flexible templates for curved openings. We record frame depth, jamb squareness, sill condition, and every angle or radius. You keep the measured survey; it becomes the basis for the quote and the fabrication order. Photos document the existing condition for our file and yours.
- 2
Written quote with fixed specifications. Haven Clause 1 requires that the measurement and the quote are the same document. Your written price lists the exact manufacturer, series, dimensions, glazing package, hardware finish, and installation scope. The price does not change unless you change the scope; there are no change orders for conditions we should have seen.
- 3
Template verification and fabrication. For arched and complex shapes, we return with physical templates when required by the manufacturer. The template is matched to the opening and photographed for the record. Only after verification does the order release to fabrication; this is where most geometric window failures begin, and where our process prevents them.
- 4
Installation by verified crew. Haven Clause 3 means the technician at your door is background-checked, uniformed, and identified by license number before arrival. The crew works from the written scope, not from memory or reinterpretation. Installation includes proper flashing, sealant integration, and operational testing of any operable components.
- 5
Documented completion and 365-Day Done Right Promise. The job finishes with a photo record of the completed installation, a walkthrough with the homeowner, and written warranty documentation. The 365-Day Done Right Promise is stamped on every job under the Haven Standard: if it’s not done right, we make it right. The photo record, the warranty, and our contact information go in your file.
How Much Does Custom & Geometric Windows Cost in Lantana?
A typical geometric shaped window in Lantana runs $1,200-$2,800 depending on complexity, size, and whether impact glazing is required. Arched and curved units typically fall in the $1,800-$3,500 range because of template costs and specialized fabrication. Oversized openings start around $2,500 and can exceed $4,500 when structural reinforcement, crane rental, or multi-panel configurations are needed. Custom impact windows with laminated glass and reinforced frames generally add 30-40% over non-impact equivalents, reflecting the Florida Product Approval testing and materials.
Several factors move the price within these ranges. Shape complexity is the primary driver: a simple trapezoid costs less than a compound radius with integrated muntins. Glazing specification matters too; low-E coatings, argon fill, and laminated interlayers each add performance and cost. Frame material affects both price and longevity in Lantana’s salt air, with thermally broken aluminum and reinforced vinyl commanding premiums over standard vinyl. Installation difficulty, including height access, stucco repair, and interior trim matching, is assessed during the measured survey and included in the written quote.
To avoid overpaying, get the specification in writing and compare like to like. A quote that omits the manufacturer series, the design pressure rating, or the glazing package isn’t comparable to one that includes them. Our free second opinion on any written estimate exists for exactly this situation; bring us a competitor’s quote and we’ll review the specifications at no charge. Every estimate we provide is free, includes the measured survey you keep, and carries no obligation. Call (561) 461-2062 for an exact quote on your specific opening.

Frequently Asked Questions - Custom & Geometric Windows in Lantana
Custom and geometric windows are manufactured to specific dimensions and shapes rather than pulled from standard size matrices. They include triangles, trapezoids, arches, circles, and compound shapes, as well as oversized rectangles that exceed manufacturer stock dimensions. In Lantana, we specify these when the architecture demands it, when replacing discontinued original windows, or when standard units won’t properly fill a non-standard opening. Call (561) 461-2062 to discuss whether your project requires custom fabrication.
Fabrication lead time for custom and geometric windows typically runs 6-10 weeks depending on manufacturer, complexity, and current demand. The installation itself usually completes in one day for single openings, or two days for multiple units or oversized configurations. We schedule installation only after the fabricated unit arrives and we’ve verified it against the template; in Lantana, we see the longest delays when customers order without templating, so our process includes that verification step. Call (561) 461-2062 to check current lead times for your specific shape and manufacturer.
Custom and geometric windows in Lantana typically cost $1,200-$4,500 per opening depending on shape complexity, size, glazing specification, and whether impact rating is required. Arched units generally start around $1,800; oversized openings with structural requirements can exceed $4,500. The measured survey determines the exact specification, and the written quote you receive names the exact price before any order is placed. Call (561) 461-2062 for a free estimate with no obligation.
Yes. We specify and install custom and geometric units from CGI, CWS, ES Windows, ECO Window Systems, and our other verified manufacturer lines. Our experience with CGI includes hundreds of impact-rated architectural shapes across Palm Beach County, including our Custom & Geometric Windows in Royal Palm Beach, and we regularly template CWS geometric vinyl frames for Lantana’s coastal environment. Whether your project specifies one of these brands or you need guidance on which line suits your opening, we can specify by performance tier and price range. Call (561) 461-2062 to review manufacturer options for your project.
We do not offer same-day installation for custom windows, which require measured survey, templating, and fabrication before any unit can be produced. For openings with broken glass or compromised security, we can provide temporary board-up and weatherproofing while the custom unit is fabricated. Calls are answered by a live person 24/7, so we can assess the situation and schedule protective measures immediately even when fabrication is required. Call (561) 461-2062 for emergency assessment and temporary protection.
Every installation is covered by our 365-Day Done Right Promise under the Haven Standard: if it’s not done right, we make it right. Manufacturer warranties on the window itself vary by line, with most offering 10-20 years on the frame and glass, and lifetime coverage on some premium series. The written scope you approve before installation specifies the exact warranty terms for your selected manufacturer and series. Call (561) 461-2062 for warranty details on specific product lines.
Clear access to the interior and exterior of the opening, remove window treatments if possible, and gather any documentation of the existing window’s manufacturer or age. If you’re matching existing windows elsewhere in the home, note their locations so we can measure for consistency. The measured survey takes 30-60 minutes for most custom openings; you keep the documentation, and the written quote follows within 24 hours. Call (561) 461-2062 to schedule your free measured survey and estimate.
