Fast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric window replacement in Kendall, FL typically runs $2,500-$5,000 per large or custom opening, with standard impact windows landing between $800 and $1,500 installed. Every arched, radius, trapezoid, or oversized unit has to carry a Miami-Dade Notice of Acceptance (NOA) to pass inspection here, because Kendall sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone. That’s not a suggestion. It’s the law. Call (863) 251-5864 and we’ll walk you through what your specific opening actually needs before you spend a dime.
Winslow Windows & Doors has been installing custom shapes and impact-rated glass in Kendall for over a decade. We know the difference between a 1975 CBS rancher off Kendall Drive and a newer build near West Kendall Baptist Hospital. We know which openings need masonry infill and which ones can take a direct replacement. Ed Winslow’s name is on the door, and on every job we do.

Our Custom & Geometric Windows Services in Kendall
Kendall homes throw more curveball openings at us than almost any other part of Miami-Dade. Trapezoids over front doors, radius transoms on 1980s villas, oversized picture openings on lakefront lots. Our Custom & Geometric Windows team handles all of it, and we coordinate scheduling and dispatch from our Miami (South FL) office so Kendall jobs get crewed locally and quickly.
Custom Impact Windows
Most standard stock windows top out around 60 inches wide and have rectangular frames. Kendall homes rarely cooperate. When you need a unit sized to an odd opening that also has to survive a Category 5 wind event, it has to be fabricated, not pulled off a shelf. We order custom impact windows with Miami-Dade NOA documentation for every configuration. The glass is laminated, the frames are reinforced, and the engineering is matched to your home’s specific wind zone and elevation.

Geometric & Shaped Windows
Triangles, pentagons, octagons, trapezoids. These are common on Kendall’s 1970s and 1980s ranch homes, especially above entry doors and in vaulted great rooms. But here’s what matters: not every shape can legally be made as an impact window. Each geometry needs its own product approval under HVHZ. We’ll tell you upfront whether your opening can be fabricated as-is or needs to be modified to a certifiable profile. That honesty saves Kendall homeowners weeks of waiting and thousands in reorder costs.

Arched & Curved Windows
Arched windows are the hardest to get right in a hurricane zone. The curved top has to hold a certified impact-rated sash without bowing under wind load, and the springline where the curve meets the jamb is a common leak point if the flashing isn’t installed perfectly. We’ve replaced enough arched units in Kendall to know exact template profiles on sight. Radius windows, half-rounds, elliptical heads: we measure, fabricate, and install them to a tolerance that passes Miami-Dade inspection the first time.

Oversized Openings
Kendall has its share of wide picture windows facing backyard pools, lakes, and golf course views. A heavy impact-rated insulated glass unit in an oversized opening puts real load on the header above it. Pre-1990 Kendall homes sometimes have undersized reinforced lintels that were fine for single-pane glass and nowhere near adequate for a tripled-up impact unit. We check the structural load path on every oversized job. If a steel header needs to go in, we tell you in the estimate, not as a surprise change order mid-install.

Trusted Brands We Service in Kendall
We’re an authorized installer for eight premium window and door brands, and the ones that matter most for Kendall custom work are ES Windows, ECO Window Systems, and Mr-Glass. ES Windows does exceptional radius and trapezoid fabrications with Miami-Dade NOAs already in hand. ECO Window Systems handles large fixed picture openings cleanly. Mr-Glass is our go-to for oddball geometric profiles that other fabricators won’t touch. Because we are factory-authorized for these lines, we order direct and keep turnaround predictable, which means your Kendall project doesn’t sit in a queue behind a dozen other installers waiting on the same distributor.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Non-NOA arched and radius windows failing inspection. A custom arch without a Miami-Dade NOA gets red-tagged at rough inspection in Kendall, period. The homeowner paid for the window, paid for the install, and then has to tear it out and reorder. We never quote a custom shape without confirming the NOA exists for that exact profile first.
- Jalousie windows that cannot be legally retrofitted. Pre-1980s Kendall neighborhoods are full of louvered glass jalousies, and there is no approved impact retrofit for them under HVHZ. Replacement means rebuilding the rough opening with masonry infill and re-stucco. It’s a line item cheap quotes omit, which is why their numbers look lower than ours at first glance.
- Mulled geometric assemblies splitting at the jamb. When a contractor stacks standard impact units together to fake a bay or trapezoid shape, the mullions between them carry enormous shear under design pressure. Without individual engineering approvals on each mullion, the assembly fails. We see this on Kendall homes where a previous “deal” install is already sagging or splitting.
- Water intrusion at floor level on slab-on-grade homes. Kendall’s flat terrain means standing water after afternoon downpours is routine. Aging door thresholds and low sill heights on 1970s CBS homes let that water under the frame, rotting subfloor and corroding tracks. When we install in Kendall, sill pan flashing and positive drainage always get addressed as part of the job.
Pricing for Custom & Geometric Windows in Kendall, FL
Impact windows in Kendall generally run $800-$1,500 per unit installed, with large or custom openings climbing to $2,500-$5,000. A custom trapezoid or radius unit with an ES or PGT NOA will land in that higher range because the fabrication is bespoke and the engineering is per-opening. Whole-home packages across four or five bedrooms in Kendall settlements can run $8,000-$25,000 or more depending on opening count, frame material, and how much masonry work the jalousies and odd shapes pull in.
What moves the price in Kendall specifically: the number of openings, whether the home is in a flood-zone-adjacent wind exposure category, second-floor elevations that require higher design pressures, and whether we’re doing a straightforward frame-out or rebuilding rough openings with infill. You’ll get a written line-item quote before any work starts. Call (863) 251-5864 to schedule a free in-home measure.

FAQs - Custom & Geometric Windows in Kendall
Yes, NOAs exist for certain trapezoid, radius, and arched profiles, but only from a small set of fabricators: ES Windows, PGT, CGI, CWS, ECO, and Mr-Glass among them. Each geometric shape is certified separately, so we verify the exact profile against the NOA database before we order. If your specific opening shape doesn’t have an NOA, we’ll tell you and adjust the design to something certifiable rather than risk a failed inspection. Call (863) 251-5864 for a free measurement and we’ll check your opening against the approval list same week.
Jalousie windows add masonry infill and re-stucco to every quote, because they cannot be retrofitted to meet HVHZ impact standards under any Miami-Dade NOA. The louvered glass and crank mechanism have to come out, the rough opening gets rebuilt with block and mortar, and then the new impact unit goes in. On a 1978 CBS rancher off Kendall Drive near Killian Parkway, we replaced three original jalousies and a custom trapezoid above the front door. The jalousies required full infill and re-stucco, and the trapezoid was fabricated as a fixed impact-rated PGT Custom Window with laminated glass. Plan for $300-$600 in masonry work per jalousie opening on top of the window cost. Call (863) 251-5864 to get an exact breakdown.
Kendall is in Miami-Dade’s High Velocity Hurricane Zone, and design pressures for any replacement window are calculated per-opening based on wind speed, roof height, and exposure category. Most Kendall homes need units rated between +/-50 and +/-90 PSF, though second-story openings and wide spans can push higher. We never install anything rated above +/-100, because no residential opening in this market requires it and over-speccing wastes money. Your permit set will list the required DP for each opening, and our quote matches it exactly. Call (863) 251-5864 for a no-trip-charge evaluation.
It can, after a wind-mitigation inspection documents the upgrade. Kendall homeowners who replace non-impact single-pane aluminum and jalousies with NOA-certified impact units and then file a wind-mitigation form typically see windstorm-premium credits averaging around 25% on the windstorm portion of the policy. The inspection itself runs $75-$150. Citizens doesn’t guarantee a specific percentage, but an NOA-backed install with the right paperwork is exactly what their underwriters look for. We provide the product approval documentation for every unit we install so you can file cleanly. Call (863) 251-5864 and we’ll explain what documentation comes with your job.
Yes, if the curve radius matches an NOA-certified profile from one of our fabricators. We template the existing opening in person, cross-reference the radius against the ES Windows and PGT approval libraries, and quote only what will pass Miami-Dade inspection. If the curve is off-profile, we size the new unit to a certifiable radius and rebuild the opening to match, including re-flashing before permit inspection. Aesthetic curves and HVHZ compliance don’t have to be enemies. Call (863) 251-5864 for a free in-home template and quote.
What Custom & Geometric Windows Costs in Kendall
Real numbers for Kendall, no vague language. Impact windows generally run $800-$1,500 per window installed. Impact single-hung units land between $900 and $1,800. Large or custom openings with arched, radius, or trapezoid glass run $2,500-$5,000 per unit because of the bespoke fabrication and per-opening engineering. Whole-home packages across a typical 4-bedroom Kendall ranch run $8,000-$25,000 and up depending on the mix of jalousies, geometric windows, and oversized openings.
What moves the price: opening count, wind zone (every Kendall address is HVHZ, but second-floor and wide-span openings require higher DP ratings), frame material, and masonry infill on jalousie replacements. Big-box retail installs look cheaper because they don’t include infill, structural headers, or the permit engineering a legal Kendall install requires. We do. Our free in-home measure gets you a written line-item quote with every cost visible. Call (863) 251-5864 to book yours.
Florida Pays You Back
The incentives stack if you qualify. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades including impact windows and doors. Florida exempts impact-resistant windows and doors from sales tax. There’s a federal 25C energy credit worth 30% of product cost, up to $600 per year on qualifying units. And windstorm-premium credits after a wind-mitigation inspection, around $75-$150, average about 25% off the windstorm portion of your premium. The grant program and your carrier set the final numbers, so we can’t guarantee a payout. We can guarantee the installation will be documented properly so you’re eligible to file. Impact windows beat hurricane shutters every time in Kendall: permanent protection, no panels to drag out of the garage at 11 p.m., no climbing ladders in the rain. And we never sell shutters, so you’ll get a straight answer on the comparison.
