Since 2012, we’ve installed more than 18,000 windows and doors under the Haven Standard, and a growing share of those openings have been custom or geometric shapes in Princeton and surrounding Miami-Dade County communities, similar to our Homestead Custom & Geometric Windows service area. Homeowners here face a specific challenge: the combination of strict Florida Building Code wind-load requirements and the desire for architectural character that standard rectangular units cannot deliver. Arched transoms above entry doors, circular accent windows in gables, trapezoid flankers alongside fixed picture units, and oversized geometric assemblies for modern homes - each requires a measured survey that accounts for structural opening, sightline alignment, and manufacturer fabrication tolerances.

We don’t stock custom shapes. No one does. What we do is specify the right manufacturer line for your opening’s performance requirements and your budget, then manage the measured survey, fabrication lead time, and installation sequence so the unit that arrives matches the document you approved. Every Princeton job begins with a measured survey you keep, and the written quote cannot differ from that document. Haven Clause 1.

What Our Custom & Geometric Windows Service Includes

Custom Impact Windows

Custom impact windows are non-rectangular units fabricated with laminated glass and reinforced frames to meet Miami-Dade County’s HVHZ (High Velocity Hurricane Zone) requirements. You need these when your architectural plans call for shaped openings in wind-borne debris regions - which is all of Princeton - or when you’re replacing existing custom shapes that failed, leaked, or no longer meet current code. At Sightline Windows & Doors Princeton, we specify custom impact units from PGT, CGI, and ECO Window Systems based on your opening’s design pressure rating and your preference for aluminum or vinyl construction. We measure the rough opening to 1/16 inch, document the sightline alignment with adjacent units, and the written quote includes the design pressure rating, glass make-up, and frame finish before any fabrication begins.

Geometric & Shaped Windows

Geometric and shaped windows include triangles, trapezoids, pentagons, octagons, and other non-rectangular configurations used as accent pieces or in grouped assemblies. You need these when you’re adding architectural interest to a gable end, flanking a fireplace with matching angles, or completing a contemporary facade with irregular glazing patterns. Sightline specifies Coral Gables Custom & Geometric Windows and geometric units from ViewLux and CWS for Princeton homes, selecting fixed or operable configurations based on ventilation requirements and the structural limitations of the opening. Because geometric shapes cannot be field-modified, our measured survey includes a full-size template verification when the manufacturer requires it, and we photograph the opening before and after to document that the installed unit matches the approved drawing.

Arched & Curved Windows

Arched and curved windows feature radius tops, half-rounds, elliptical shapes, or full circular configurations. You need these when restoring or replicating Mediterranean, Spanish Colonial, or traditional Florida architecture common in Princeton’s established neighborhoods, or when adding a radius transom above a new entry door or French door assembly. We source arched units from Therma-Tru and Mr-Glass with radius tolerances specified to the manufacturer’s capability - typically within 1/4 inch for vinyl and 1/8 inch for aluminum. The Haven Standard requires that we verify the springline height and chord width at three points across the opening, because arched rough openings in block construction are rarely perfectly true. Your measured survey includes these readings, and the fabrication drawing requires your signature before production begins.

Oversized Openings

Oversized openings exceed standard manufacturer unit dimensions and require engineered solutions for structural support, glazing weight, and wind-load resistance. You need these for modern great-room walls, corner-window assemblies, or commercial-scale residential features where a single field of glass is desired. Sightline manages oversized installations in Princeton using reinforced frames from ES Windows and PGT, with steel or aluminum structural supports engineered to Florida Building Code Chapter 16 loads. These projects require permit submittal, and we include permit drawings, structural calculations, and inspection scheduling in our written scope. The measured survey for an oversized opening includes deflection analysis of the header and documentation of any floor settlement that could affect operability over time.

Brands We Service for Custom & Geometric Windows

We specify custom and geometric windows from eight verified manufacturer lines, selected by what your opening requires rather than what sits in a warehouse. For impact-rated custom shapes in Princeton, we regularly draw from ECO Window Systems for their aluminum geometric capabilities and competitive lead times on non-rectangular impact units; we’ve specified more than 200 ECO custom shapes since 2018, and their Miami-area fabrication facility reduces shipping damage risk for radius and angled units. Mr-Glass supplies our decorative and specialty glazing needs, including curved laminated glass for interior applications and custom insulated units with integrated SDL (simulated divided lite) patterns that replicate traditional arched window aesthetics without the thermal penalty of true divided lites.

For arched and radius-top configurations, Therma-Tru provides fiberglass and steel frame options with factory-applied arch templates that integrate with their door systems - critical when the arched transom must match a specific entry door profile. ViewLux handles our vinyl geometric and oversized requirements, with welded-frame construction that maintains shape integrity in Florida’s thermal cycling conditions. Whether you have ECO Window Systems, Mr-Glass, Therma-Tru, ViewLux, or any other make, we can specify, measure, and install the replacement or new construction unit. Our measured survey identifies the existing manufacturer when possible, and we cross-reference serial numbers and fabrication marks against our database of 18,000+ completed openings.

Signs You Need Custom & Geometric Windows Right Now

• Visible daylight around a shaped frame perimeter. Geometric and arched windows rely on precise frame-to-opening contact that rectangular shims cannot correct. If you see consistent gaps at the radius or acute angles of a shaped unit, the frame has likely shifted in the opening or the original installation lacked proper anchoring at stress points. Water intrusion follows quickly in Princeton’s driving rain conditions, and the repair requires full replacement with a correctly measured unit.
• Condensation between glass lites on a custom insulated unit. Custom shapes use edge spacers that are hand-fabricated or thermally formed, and the seal integrity is more vulnerable than on standard rectangles. Fogging or mineral deposits inside the glass indicate seal failure; the unit cannot be resealed in the field, and replacement requires matching the original fabrication drawing or completing a new measured survey.
• Cracked or delaminating impact glass in a geometric unit. Impact-rated laminated glass in custom shapes experiences edge stress concentration at corners and radius transitions. A crack originating from these points compromises the entire wind-borne debris protection of the assembly, and Princeton’s HVHZ requirements mean the unit no longer provides code-compliant protection. Replacement must replicate the original design pressure rating.
• Operating sash that binds or won’t close in an arched or trapezoid window. Non-rectangular operable units depend on precise hinge and lock alignment that shifts as the structure settles. Binding indicates frame racking or hardware misalignment that will eventually distort the sash weatherstrip seal. In Princeton’s coastal climate, this gap admits salt air and accelerates hardware corrosion.
• Planned renovation or addition with non-standard openings. If your architectural plans include geometric shapes, arched elements, or oversized glazing, the window specification must precede rough framing. Sightline’s measured survey during the framing stage identifies conflicts between the architect’s drawing and the actual structural limitations, before drywall and finish materials make correction expensive.

Our Custom & Geometric Windows Process - Step by Step

1. 1
   Initial consultation and scope definition. We discuss your architectural requirements, performance needs, and budget range. For new construction or additions in Princeton, we review your architectural drawings and identify manufacturer lines capable of producing the specified shapes within Florida Building Code constraints. For replacements, we photograph the existing unit, record any visible manufacturer markings, and assess the opening condition. You receive a written scope summary before we proceed to measurement.
2. 2
   Measured survey with documented readings. Our technician arrives in uniform with license number provided in advance under Haven Clause 3. For custom and geometric openings, we measure width at three heights, height at three widths, and diagonal squareness. For arched units, we record the chord width, rise, and springline height at minimum five points. For oversized openings, we assess header deflection under load and document floor level. You keep the measured survey; it becomes the basis for the written quote and the fabrication drawing.
3. 3
   Manufacturer specification and written quote. We select the manufacturer line based on your opening’s requirements: impact rating, frame material, finish, and lead time. The written quote includes the unit price, installation labor, permit fees if applicable, and any structural support or trim work. Haven Clause 1: the quote cannot exceed the measured survey document. For custom shapes, we attach the manufacturer’s fabrication drawing for your approval signature.
4. 4
   Fabrication and delivery coordination. Custom and geometric units typically require 4-8 weeks fabrication depending on complexity and manufacturer backlog. We coordinate delivery to minimize on-site storage in Princeton’s humid conditions, and we inspect each unit upon arrival for shipping damage and dimensional accuracy against the approved drawing. Any discrepancy is documented photographically and resolved with the manufacturer before installation scheduling.
5. 5
   Installation, inspection, and documentation. Our crew installs per the manufacturer’s published instructions and Florida Building Code requirements, with permit inspections scheduled as required for impact-rated or oversized installations. Upon completion, we photograph the installed unit from interior and exterior, document the serial numbers and ratings, and provide you with the photo record, warranty documentation, and the 365-Day Done Right Promise under Haven Clause 5. No surprises.
