Olympia Heights sits in Miami-Dade’s inland corridor where the limestone substrate and strict wind-borne debris codes create specific constraints for shaped and oversized openings. We’ve measured arched transoms in homes near Coral Way that required steel-reinforced frames to meet HVHZ requirements, and we’ve specified our Custom & Geometric Windows in Hialeah and geometric assemblies for properties along Flagami’s mid-century streets where original aluminum windows have fatigued past repair. The Haven Standard governs every engagement: Have it in writing, Arrive on schedule, Verified crews, Evidence on every job, No surprises.

Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. The written price you receive after measurement is the price on the final invoice. No change orders, no “discovered” conditions that inflate the scope. We document every visit with dated photographs, and every installation carries the 365-Day Done Right Promise written into the Haven Standard, not offered as a courtesy.

What Our Custom & Geometric Windows Service Includes

Custom Impact Windows

Custom impact windows are manufactured to non-standard dimensions or shapes while maintaining Miami-Dade County’s HVHZ certification for wind-borne debris protection. In Olympia Heights, we regularly specify these for openings where stock impact units won’t fit - whether that’s a trapezoid overlooking a pool patio or a narrow vertical light flanking a front entry. Sightline measures the rough opening to the sixteenth, records the existing frame’s attachment method to the CMU or wood framing, and specifies the custom laminated glass package, reinforced sash, and anchoring pattern required for permit approval. Our measured survey includes a photo sequence of the opening from interior and exterior, the frame reading, and the sightline dimension - the visible glass area once the new unit is installed. That document becomes your written quote.

Geometric & Shaped Windows

Geometric and shaped windows include triangles, pentagons, octagons, and other polygonal configurations that break from rectangular stock. These appear frequently in Olympia Heights homes built during the 1960s and 1970s where architects used angular glazing to capture north light without direct solar gain. We specify geometric units from manufacturers including CWS and ECO Window Systems, selected by performance tier and price range rather than margin. The critical detail is the insulated glass unit’s edge seal geometry - irregular shapes stress the seal differently than rectangles, and our specification includes the spacer type, desiccant fill, and warranty term for the IGU. We’ve replaced geometric assemblies in homes near West Flagler where the original units had failed at the acute-angle corners after twenty years of thermal cycling.

Arched & Curved Windows

Arched and curved windows require either true-radius manufacturing or segmented approximation depending on the span and the manufacturer’s capability. In Olympia Heights, we encounter true arches in Mediterranean-influenced homes near Coral Gables Custom & Geometric Windows-adjacent streets, and segmented arches in more recent construction where the radius exceeds practical glass-bending limits. Our measured survey records the chord length, rise, and radius for true arches; for segmented units, we document the number of lites, the mullion angles, and the sightline interruption at each joint. CGI manufactures a true-radius impact arch that we’ve specified for openings up to 72 inches wide, while ES Windows produces segmented assemblies with narrower sightlines for larger spans. The written quote names the manufacturer, the glass package, and the lead time - typically 6-10 weeks for custom curved units.

Oversized Openings

Oversized openings exceed standard manufacturing dimensions and require engineered solutions for structural support, glass thickness, and installation sequencing. In Olympia Heights, we see these in contemporary renovations where multiple standard openings are combined into single visual planes, or in original mid-century homes with floor-to-ceiling glass walls that have exceeded their service life. Our process includes a structural assessment of the header and jack studs, specification of tempered or heat-strengthened glass based on size and exposure, and coordination with a structural engineer when the opening modification requires permit drawings. We’ve installed oversized units up to 120 inches in width using CWS’s commercial-grade framing with thermal break, specified for the specific wind load at the Olympia Heights address rather than a generic Miami-Dade rating.

Brands We Service for Custom & Geometric Windows

We draw from eight verified manufacturer lines, specified by what the opening requires rather than what is in stock. For custom and geometric windows in Olympia Heights, we regularly specify CWS for geometric and oversized assemblies where the project demands narrow sightlines and high thermal performance - their aluminum-thermal-break framing accommodates custom angles without the bulk of older systems. We’ve measured and installed hundreds of CWS units across Miami-Dade since 2012, and our specification library includes their full custom geometry catalog with current lead times and glazing options. ES Windows contributes their segmented arch and oversized capabilities, particularly for projects where the budget constraints favor a two-week lead time over true-radius manufacturing. Their impact-rated geometric line carries Miami-Dade County approval for shapes up to octagonal, and we’ve specified their units for renovations in Glenvar Heights and Westchester where permit timing drove the selection.

ECO Window Systems provides custom impact solutions at a mid-tier price point, with geometric capabilities that include trapezoids, triangles, and segmented arches in vinyl and aluminum framing. We’ve found their vinyl custom line particularly suitable for Olympia Heights homeowners replacing original aluminum windows in ranch-style homes where thermal improvement is the primary objective. For any brand in your existing home - or if you’re selecting new - our free second opinion on any written estimate means you can bring us a competitor’s specification and we’ll review the glass package, frame rating, and anchoring detail at no charge. Whether you have CWS, ES Windows, ECO Window Systems, or any other make, we can measure, specify, and install to the Haven Standard.

Signs You Need Custom & Geometric Windows Right Now

• Visible condensation between glass panes indicates seal failure in the insulated glass unit, which is especially common in geometric shapes where the edge seal experiences uneven thermal stress. In Olympia Heights’ humid climate, failed IGUs accelerate frame corrosion and reduce the opening’s insulating value to that of single-pane glass. We document seal failure with close-up photography and specify replacement IGUs or full unit replacement depending on frame condition.
• Cracked or delaminating impact glass compromises the wind-borne debris protection required by Miami-Dade code, even if the crack appears minor. Custom and geometric impact units cannot be field-repaired; the laminated glass package must be manufactured to the specific shape and installed as a complete assembly. We’ve replaced cracked geometric impact units in homes near Bird Road where the original installer had used non-impact-rated custom shapes that failed inspection.
• Frame separation or corner gaps in aluminum or vinyl custom windows allow water intrusion that damages interior finishes and promotes mold growth in wall cavities. Geometric frames are particularly susceptible because the mitered corners at acute angles carry higher stress than standard 90-degree joints. Our measured survey includes a frame-square reading and corner-gap measurement; if the frame has racked beyond 1/8 inch, we specify full replacement rather than attempted repair.
• Operational failure in operable geometric units - windows that won’t open, won’t stay open, or won’t lock - typically indicates hardware fatigue or frame distortion. Custom shapes often use specialized hinge and lock hardware that is no longer available; we identify the hardware series during measurement and confirm current availability before quoting. In homes near Olympia Heights’ older sections, we’ve encountered discontinued hardware that required full unit specification to achieve operability.
• Draft or temperature differential near the window suggests air infiltration through failed weatherstripping, frame deformation, or improper original installation. Our diagnostic includes a smoke-pencil test at the frame perimeter and a thermal-image reading where accessible; the measured survey records the leakage path and specifies the sealing detail for the replacement unit. For oversized openings, we pay particular attention to the meeting-stile compression and the sill-pan drainage path, both common failure points in original installations.

Our Custom & Geometric Windows Process - Step by Step

1. 1
   Initial phone consultation and scheduling. When you call (786) 400-2761, a live person answers - not a voicemail queue, not a callback window. We confirm your address in Olympia Heights or surrounding areas, discuss the opening type and your objectives for the replacement, and schedule a measured survey. For custom and geometric work, we allow 60-90 minutes for the initial visit depending on the number of openings.
2. 2
   Measured survey with documented photo record. Our technician arrives in uniform, presents their license number, and conducts a complete opening measurement including rough-opening dimensions, frame condition, structural attachment, and sightline requirements. We photograph the opening from interior and exterior, the existing frame label if legible, and any adjacent finishes that affect installation sequencing. You keep a copy of the measured survey; it becomes the basis for the written quote.
3. 3
   Written quote and product specification. Within 48 hours of measurement, you receive a written quote naming the manufacturer, product series, glass package with U-factor and SHGC values, frame finish, hardware, and installation scope. For custom and geometric units, the quote includes the shape drawing, lead time, and any engineering or permit requirements. The price on this document is the price on the final invoice - Haven Clause 1, No surprises.
4. 4
   Permit application and product ordering. Sightline pulls all required permits and schedules inspections; you are not responsible for permit office coordination. For custom units, we order upon your approval of the written quote and deposit, then confirm the manufacturer’s production schedule. We notify you when the unit ships and schedule installation to arrive within 48 hours of delivery to our warehouse.
5. 5
   Installation, inspection, and documented completion. Our crew installs per the manufacturer’s specification and the engineered anchoring detail, with the lead technician documenting each phase with dated photographs. The final inspection is conducted with you present; we demonstrate operation, cleaning, and warranty registration. You receive the completed Haven Standard packet: measured survey, written quote, photo record, permit approvals, and warranty documentation. The 365-Day Done Right Promise is in effect from this date.
