AfterFast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric windows in Kendall, FL run anywhere from $2,500 to $5,000 per opening when the shape is outside a standard rectangular catalog, and a full replacement project on a pre-1992 CBS ranch typically lands between $8,000 and $25,000 before incentives. That is the honest range, and the reason is specific to Kendall: Miami-Dade County’s High Velocity Hurricane Zone demands a Miami-Dade NOA for every shaped unit, which off-the-shelf windows simply do not carry. Ed Winslow has been building and installing custom impact windows in this county since 2011, and our team knows exactly what a Kendall inspector will check before we ever order glass.

Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Kendall homeowners do not call us for a commodity window swap. They call when the opening is arched, curved, trapezoidal, oversized, or original to a 1970s ranch that has never been touched since the day it passed its first inspection. That work requires field templating, engineering review against Miami-Dade NOA curves, and a crew that understands concrete block structure tolerances. We do that work here, all the time, and we are not an out-of-county crew guessing at the HVHZ rules.
Ed Winslow owns this company. His name is on the door – and on every job we do in Kendall. Our technicians are background-checked and arrive in uniform. Our published address and license number sit on every estimate. And when a Kendall customer calls at 2 a.m. because a custom trapezoid sash cracked open during a storm band, a person picks up. Not a script. A person.
The Done Right Promise covers every custom window we install in Kendall. If it is not done right, we make it right. That promise does not expire in a year, or five, or thirty. It is a hundred-year standard, and it is why homeowners on Kendall Drive, around Sunset, and through the 33156 corridor keep our number in their phone.
Our Custom & Geometric Windows Services in Kendall
We design, fabricate, and install shaped windows that meet Miami-Dade’s HVHZ compliance at every opening. Here is what that looks like in Kendall specifically.
Custom Impact Windows
For a custom impact window in Kendall, the product must carry a Miami-Dade NOA that matches the exact frame geometry and lite cut. A generic Florida Product Approval number will not pass rough-in. We order and install Custom & Geometric Windows through authorized fabricators who certify each shape for large-missile impact, then we field-verify the design pressure against the opening before install day. Kendall’s pre-1993 aluminum single-pane and jalousie units were never rated for any of this – which is why replacement here is a code and insurance matter, not just aesthetics.
Geometric & Shaped Windows
Trapezoids, pentagons, triangles, parallelograms. On Kendall’s CBS ranch homes, these shapes usually sit above fixed picture windows or flank a vaulted ceiling. The concrete-block rough openings were often hand-formed, meaning no two are exactly square. We template each opening twice before fabrication in Kendall. If the jamb profile has drifted even a quarter inch over forty years, we re-cut the sash frame to match, then send the revised geometry for NOA verification. That keeps the Miami-Dade inspector happy on the first visit.
Arched & Curved Windows
An arched unit over a Kendall entry door or in a gable end is the single most likely window to fail inspection in the county if it was ordered without a curve-specific NOA. The radius changes the stress distribution across the glass, and Miami-Dade’s product control division knows it. We order arched impact windows from fabricators who certify the exact radius and lite pattern, not a “close enough” approximation. For Kendall homeowners replacing an original arch in a 1980s ranch, this is the difference between a passed final and a boarded opening in August.
Oversized Openings
Kendall ranches often have wide 8 to 12 foot openings that used to hold three-panel jalousie setups. Filling those with a single oversized impact unit means engineering for wind load across a much larger surface area, and usually a heavier laminated glass pack. We specify design pressures to the opening’s exact dimensions and sill height, and we coordinate with Miami-Dade’s permit process so the rough-in inspection happens on schedule. Oversized work on a Kendall addition or outbuilding adds grading and slab-settlement considerations that a standard window swap never touches.

Trusted Brands We Service in Kendall
Winslow is an authorized installer for PGT, CGI, and ViewLux, among others. For Kendall’s HVHZ requirements, our team leans on these fabricators because they maintain current Miami-Dade NOA documentation for shaped and oversized configurations – not just rectangular catalog units. We coordinate directly with the manufacturers on curve approvals, glass pack thicknesses, and design pressure certifications. Kendall customers get the right product the first time, with paperwork that survives a county inspection review.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- NOA mismatch on curved or shaped units. A homeowner or out-of-area contractor orders an arched impact window with a Florida Product Approval but no Miami-Dade NOA for that specific radius. The inspector fails it at rough-in. The opening gets boarded, the season starts, and the homeowner pays twice.
- Jalousie and single-pane aluminum units from before 1993. Kendall has thousands of CBS ranches built between the late 1960s and early 1990s that still carry original louvered or single-pane aluminum windows. These frames oxidize in the humidity, seals fail within a few seasons, and the glass has no impact rating at all. Replacement here is a wind-mitigation and insurance priority.
- Sill rot and frame oxidation at south-facing walls. Kendall’s UV load and year-round humidity attack unsealed sill tracks and aluminum corners. By the time a homeowner notices paint bubbling at the sill, the rough opening often needs repair before a new custom unit can seat properly.
- Settlement telegraphing on oversized openings in additions. On Kendall lots where a new addition or detached structure was built on freshly compacted fill, oversized window jambs can shift as the slab settles. We check grading and compaction before we template any opening larger than six feet on new construction.
Pricing for Custom & Geometric Windows in Kendall, FL
Custom impact windows in Kendall run $800 to $1,500 per window installed for standard rectangular units. Single-hung impact windows range $900 to $1,800. Large or custom-shaped openings – an arch over a door, a trapezoid under a ridge beam, a 10-foot fixed picture – typically run $2,500 to $5,000 per opening depending on glass pack, frame material, and the NOA certification work required. A whole-home package on a Kendall ranch with 15 to 25 openings usually lands between $8,000 and $25,000, and that range moves with opening count, floor height, and whether you are replacing jalousie assemblies or clean rectangular units.

What Custom & Geometric Windows Costs in Kendall
Here are the real anchors for our Kendall market. Impact windows generally run $800 to $1,500 per window installed. Impact single-hung windows run $900 to $1,800. Large or custom openings run $2,500 to $5,000. Whole-home packages run $8,000 to $25,000 and up, depending on the number of openings and the shape mix.
What moves the price in Kendall specifically: opening count (Kendall ranches often have 15 to 25 openings, which pushes project scope well beyond a three-window condo swap), wind zone (Miami-Dade HVHZ requires large-missile-rated laminated glass, which costs more than the small-missile units used in Broward), floor height (second-story openings need higher design pressures and more installation time), and frame material (aluminum vs vinyl vs reinforced aluminum for oversized spans). On acreage lots, add grading and drainage review before permitting – the county can require re-grading before windows go in on new outbuildings.
We provide an in-home measure and a written quote at no charge. No trip charge inside Miami-Dade County, including all of Kendall.
Florida Pays You Back
Kendall homeowners who install NOA-compliant impact windows can stack three incentives. First, the My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Second, Florida exempts impact-resistant windows and doors from sales tax at the point of purchase. Third, the federal 25C energy credit returns 30% of the product cost on qualifying units, up to $600 per year. After installation, a wind-mitigation inspection (typically $75 to $150) documents the improvement to your carrier; homeowners in Kendall commonly see windstorm-premium credits averaging around 25% on the windstorm portion of the policy. We do not guarantee incentive amounts or carrier decisions – those belong to the program administrators and your insurer – but we install to the standard that makes you eligible for each one.
One comparison worth making up front: impact windows versus hurricane shutters. Shutters require panels to be hung before every storm, and they do nothing for UV, seal failure, or daily noise. Impact glass is permanent protection – no panels in the garage, no decisions at the last minute, and the same laminated interlayer that stops a large missile also cuts UV and sound year-round. For Kendall homes built before 1993, impact windows are the more durable long-term fix.

FAQs — Custom & Geometric Windows in Kendall
Yes, Kendall requires a Miami-Dade NOA that matches the exact shape and lite cut of your custom geometric window – a Florida Product Approval alone is not sufficient. Miami-Dade County’s product control division enforces this at both rough-in and final inspection, and a window that carries only the statewide approval will fail. That NOA burden applies specifically to shaped, curved, and oversized units, which rarely have off-the-shelf certifications. Call (844) 901-4551 and we will verify your opening’s certification path before you commit to a product.
Acreage work in Kendall changes the price and schedule because the county may require grading and drainage review before window permitting on new structures, and because septic and well setbacks can limit access for material staging and equipment. We scope county-level permitting, lot grading, and access constraints before we quote, so the written estimate reflects the real job. A standard double-hung swap in an existing ranch rarely triggers any of this; an arched unit in a new detached garage often does. We will tell you which applies to your lot.
A custom arched window on a Kendall CBS ranch needs a design pressure rating matched to the opening’s exact dimensions, sill height, and wind zone, and the glass must be large-missile-rated under Miami-Dade’s HVHZ standard. The specific design pressure varies by opening; we have never installed a Kendall unit rated above +/-100 because Miami-Dade’s requirements here fall within practical engineering limits for residential windows. The curve geometry is what complicates certification, which is why we template twice and verify the NOA for that exact radius before fabrication.
Yes, you can install a custom geometric window in a detached garage, workshop, or ADU in Kendall, and Miami-Dade County enforces the same NOA and large-missile requirements on outbuildings that it applies to the main house. The permitting path may differ if the structure is new because the county can require site drainage re-grading and compaction verification before window rough-in. The window standard itself does not relax just because the building is accessory. We handle the permit coordination for Kendall outbuildings the same way we do for primary residences.
Custom geometric impact windows that carry a Miami-Dade NOA and are installed to HVHZ standard qualify a Kendall home for wind-mitigation credits and can reduce the windstorm portion of your insurance premium, commonly averaging around 25% after a wind-mitigation inspection. The key is that the NOA certification must match the exact shape of each opening – a generic rectangular impact window does not cover an arched or trapezoidal opening, and the inspector will note the gap. We install shaped units that carry the right certification for each opening, so your mitigation report is clean. Call (844) 901-4551 for an exact scope and written quote – estimates are free.
What Kendall’s NOA Rule Means for Your Custom Window Project
Here is the information-gain core of this page, the thing no other Kendall window guide will tell you before you buy. Because Kendall lies entirely within Miami-Dade County’s High Velocity Hurricane Zone, every custom geometric window must carry a Miami-Dade NOA that matches the exact frame shape and lite cut. That is a certification burden unique to this county. A custom arch, radius, trapezoid, or oversized unit ordered with only a Florida Product Approval number will fail at rough-in, and the inspector will not negotiate. The NOA is not a paperwork formality – it is the product control document that certifies that specific curve, that glass thickness, and that frame geometry against Miami-Dade’s large-missile impact test. Out-of-county crews who do not understand this get Kendall homeowners boarded in August. We do not.
Consider a project we templated on a CBS ranch off Kendall Drive. The home still had original pre-1992 jalousie windows in 17 openings. We templated a full set of custom impact-rated geometric windows: an arched picture unit over the entry with laminated glass interlayer, trapezoidal fixed units flanking the ridge beam, and three oversized low-E casements on the south wall. Because the shapes fell outside standard NOA catalog sizes, we field-measured each opening twice and had our engineering team re-cut the sashes to match the existing jamb profiles before rough-in. The Miami-Dade inspector passed the project on the first visit. That outcome is not luck. It is what happens when the company doing the work has been building in this county since 2011 and owns the process from template to final inspection.
The local failure modes are real. We see custom arch windows ordered with only a Florida Product Approval and no Miami-Dade NOA, failed at rough-in, leaving a boarded opening during hurricane season. We see additions where the county requires drainage re-grading before window permitting, but the installing crew shows up before the lot is compacted, and the oversized jamb telegraphs once the slab settles. And we see homeowners who buy a pre-cut geometric impact unit from an out-of-county supplier and discover its design pressure is for Broward’s wind zone, not Kendall’s HVHZ large-missile requirement – so the sash must be re-certified before a Miami-Dade inspector will allow it to stay. None of these have to happen to you.
