Since 2012, Sightline Windows & Doors has installed more than 18,000 openings under the Haven Standard, every one with a written price before work started and a documented photo record when finished. North Miami’s architectural mix - MiMo homes in Sans Souci Estates, waterfront properties along Biscayne Bay, and newer construction in Ives Estates - creates demand for windows that standard catalogs don’t stock. Arched transoms, circular portholes, trapezoid clerestories, and oversized curtain walls: these require measured survey work, manufacturer coordination, and install crews who understand sightline geometry. We don’t subcontract custom work. Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. The price we write is the price you pay. No change orders, no surprises.

What Our Custom & Geometric Windows Service Includes

Custom Impact Windows

Custom impact windows are manufactured to specific dimensions and shapes while meeting Miami-Dade County’s HVHZ (High Velocity Hurricane Zone) requirements for missile impact and cyclic pressure loading. You need these when your opening is non-rectangular, oversized, or located in a wind-borne debris region where standard impact units won’t fit or won’t perform. At Sightline Windows & Doors North Miami, we measure every custom impact opening with a digital laser level and record frame plumb, level, and square to 1/16 inch; that survey becomes your written quote and our fabrication order. We specify laminated glass interlayer thickness, frame reinforcement, and anchorage pattern by engineering table, not by guess. Product lines include PGT and CGI for premium impact custom shapes, and CWS for mid-tier performance with full HVHZ certification.

Geometric & Shaped Windows

Geometric and shaped windows - triangles, trapezoids, octagons, pentagons, and compound angles - are fabricated from extruded aluminum or vinyl profiles cut and mitered on CNC equipment, then joined with structural corner keys or thermal welding. You need these when your architect or designer has specified a non-rectangular opening for daylighting, aesthetic rhythm, or to match a historical profile common in North Miami’s 1950s and 1960s architecture. We template complex shapes on-site with rigid pattern boards when digital measurement alone won’t capture the condition of an existing frame. Our Custom & Geometric Windows in Miami Gardens and geometric window installations in North Miami’s Pinewood and Westview neighborhoods regularly involve trapezoid clerestories above sliding doors and triangular gable windows in mid-century ranches. We specify ES Windows and ECO Window Systems for geometric work, selected by sightline requirements and thermal performance needs rather than inventory position.

Arched & Curved Windows

Arched and curved windows require radius bending of frame extrusions or segmental construction of flat profiles to approximate a curve, with glazing either bent thermally or cut from flat stock and edge-sealed in curved stops. You need these when your opening has a true radius top, a segmented arch, or an eyebrow curve - common in Mediterranean Revival homes near North Miami’s Arch Creek, in Custom & Geometric Windows - Pembroke Pines projects, and in custom new construction throughout Golden Glades. We distinguish between true radius work (more expensive, optically superior) and segmented flat-glass approximations (more economical, suitable for smaller radii). Our measured survey records the chord length, rise, and radius for every arched unit; that data goes to the fabricator with our order and comes back on the shop drawings you approve. Mr-Glass supplies our bent-laminated and bent-insulated glazing for curved impact applications.

Oversized Openings

Oversized openings exceed standard manufacturing dimensions - typically 60 inches in any direction for residential units - and require reinforced frames, heavier hardware, multi-point locking, and often crane or specialized lifting equipment for installation. You need these when your design calls for floor-to-ceiling glass, panoramic corner assemblies, or single-unit picture windows that standard catalogs can’t accommodate. In North Miami and for Custom & Geometric Windows - Hollywood projects, we see oversized demand in waterfront homes along Biscayne Boulevard and in new construction in Miami Shores where the view is the architecture. Our oversized process includes structural load calculations for the rough opening, engineering review of the anchorage pattern, and coordination with your general contractor on sequencing. We specify ViewLux for premium oversized non-impact applications and PGT for oversized impact-rated systems, with lift-and-slide or tilt-and-turn hardware as the opening requires.

Brands We Service for Custom & Geometric Windows

We work with eight verified manufacturer lines, specified by performance tier and price range, not by margin. For custom and geometric window work in North Miami, we most often draw from CWS, ES Windows, ECO Window Systems, and Mr-Glass. CWS produces HVHZ-certified custom shapes with fast fabrication timelines - we’ve specified hundreds of their trapezoid and arched units in North Miami and Golden Glades, plus our Custom & Geometric Windows in Hialeah, and we maintain direct factory communication on lead times and engineering exceptions. ES Windows manufactures geometric and oversized units with strong thermal break performance; we use their line when U-factor and SHGC targets are specified by energy code or homeowner preference. ECO Window Systems delivers mid-market custom shapes with reliable impact certification, and we specify them when the project needs HVHZ compliance without premium pricing. Mr-Glass is our source for bent and curved glazing, including laminated impact-rated curves that few suppliers can produce.

Whether you have CWS, ES Windows, ECO Window Systems, Mr-Glass, or any other make - PGT, CGI, Therma-Tru, or ViewLux - we can help. Our measured survey identifies the existing product line, glazing specification, and frame condition. If your windows are still under manufacturer warranty, we document that status and coordinate with the factory when appropriate. If they’re out of warranty, we quote repair or replacement with equivalent or upgraded performance. Bring us any written estimate from another contractor and we’ll review it at no charge - our Free Second Opinion on Any Written Estimate.

Signs You Need Custom & Geometric Windows Right Now

• Visible daylight around a shaped or arched frame. Gaps between the window frame and surrounding trim indicate seal failure or structural movement in the opening. In North Miami’s coastal climate, salt air accelerates corrosion at these leak points, and hurricane season turns a draft into water intrusion. We measure the gap, identify whether the frame or the rough opening has shifted, and specify a replacement that fits the true dimension.
• Fogging between panes on a geometric or custom unit. Insulated glass seal failure in shaped windows is harder to remedy than in rectangles because the spacer system follows a complex path and the glass may be tempered, laminated, or both. We test the seal with a deflectometer and quote replacement IGUs or full unit replacement based on frame condition and remaining service life.
• Cracked or chipped impact-rated glazing in a custom shape. Impact glass that has been struck by debris or stressed by building movement may retain its barrier function but lose its structural rating. We inspect for spider cracks, delamination of the interlayer, and edge damage that compromises the unit’s ability to withstand cyclic pressure. Replacement is specified to current HVHZ standards, not the standard in place at original installation.
• Operation failure in oversized or heavy units. Multi-point locks, lift mechanisms, and hinge hardware in large custom windows carry substantial load; when they fail, the sash may not seal, may not lock, or may pose a safety hazard if it drops or swings freely. We diagnose hardware failure versus frame racking, quote OEM replacement parts when available, and specify upgraded hardware when the original specification was inadequate for the sash weight.
• Energy bills rising with no other explanation. Custom and geometric windows with poor U-factor or high solar heat gain coefficient (SHGC) act as thermal collectors in North Miami’s climate. We measure frame surface temperature with an infrared thermometer and calculate the energy penalty of existing glazing versus current low-E and spectrally selective options. Replacement with properly specified units typically pays back in 7-12 years on energy savings alone.

Our Custom & Geometric Windows Process - Step by Step

1. 1
   Measured survey and documentation. Our technician arrives with a digital laser level, rigid templates for geometric shapes, and a photo documentation protocol. We record rough opening dimensions, frame plumb/level/square, existing product identification, glazing thickness, and structural conditions. You receive a copy of this survey before we leave - Haven Clause 1, Have it in writing. The survey is the basis for your quote; the quote cannot differ from the survey.
2. 2
   Written quote and product specification. Within 24 hours of survey completion, we deliver a written quote with line-item pricing for materials, labor, permits, and disposal. The quote specifies manufacturer, product line, glazing package, hardware finish, and installation details. For custom shapes, we include shop drawing approval in the timeline. For impact-rated work, we note the Miami-Dade County product approval number. The price is fixed; no change orders.
3. 3
   Fabrication and permit coordination. Upon approval, we issue fabrication orders with your survey data and shop drawings. Simultaneously, we pull permits with North Miami Building Department or the appropriate jurisdiction - Miami-Dade County for unincorporated areas, individual city offices for Golden Glades, Miami Shores, Opa-locka, and others. We schedule inspections at rough-in and final, and we pass every inspection before requesting final payment.
4. 4
   Installation with documented evidence. Our background-checked, uniformed crew arrives with the installation plan, the approved shop drawings, and the photo documentation protocol. We protect floors and furnishings, remove existing units, prepare the rough opening, install the new window with manufacturer-specified anchorage and sealants, and test operation. Every step is photographed; the photo record is uploaded to your job file within 24 hours - Haven Clause 4, Evidence on every job.
5. 5
   Final inspection, walkthrough, and warranty registration. We conduct a joint walkthrough with you, demonstrate operation and cleaning, and record any punch-list items for immediate correction. The 365-Day Done Right Promise is activated - Haven Clause 5, No surprises. Manufacturer warranties are registered in your name. Your final invoice matches the written quote, line for line.
