AfterFast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric windows in Kendall, FL typically cost $2,500-$5,000 per opening installed when you’re working with impact-rated, Miami-Dade NOA-approved units, and the process from field measure to installation runs 4-6 weeks due to custom fabrication. That’s the honest math before we even talk about your specific wall, your specific shape, and your specific insurance letter. If you’re in Kendall and you’ve got an arched opening, a trapezoid gable, or a full wall of glass that no stock window will fit, call us at (904) 478-8983 and we’ll come measure it properly.
We know Kendall because we work here constantly. Kendale Lakes, The Hammocks, West Kendall, Pinecrest-adjacent acreage off SW 88th Street and Killian Drive. Every job starts with the same question: what does the county say about this opening, and what does Miami-Dade NOA require for this exact shape?
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Ed Winslow’s name is on the door. And on every job we do in Kendall. We’ve been installing windows and doors since 2011, and when you call our number, a live person answers. 24 hours a day. That’s not a slogan. That’s how we run the business. Kendall homeowners have called us at 9 p.m. with a Citizens Insurance non-renewal letter in hand, and someone picked up on the first ring.
Our Kendall customers come to us through word of mouth mostly. A neighbor in West Kendall gets their impact windows installed, the wind mitigation report comes back clean, the insurance credit kicks in, and suddenly we’re doing three more homes on the same block. That’s the pattern. Background-checked, uniformed technicians show up, and you know exactly who’s walking up your driveway before the truck stops.
We service all of Kendall. The tract subdivisions off Kendall Drive, the older ranch homes near Dadeland, the larger lots east of Florida’s Turnpike where setback rules get complicated. Dispatch and scheduling for our Kendall work is coordinated from our Miami (South FL) office, and crews serve Kendall locally. We carry the product lines that actually pass HVHZ review here: PGT WinGuard, CGI, ES Windows, and CWS. Not whatever the big-box store had on sale.
Our Custom & Geometric Windows Services in Kendall
Every Custom & Geometric Windows job we take in Kendall begins with the Miami-Dade NOA question. Not the glass. Not the style. The NOA. If a unit doesn’t carry NOA coverage for the exact size, shape, and design pressure of your opening, it doesn’t belong on a Kendall wall.
Custom Impact Windows
Kendall falls entirely within the High Velocity Hurricane Zone, the strictest window jurisdiction in the country. Custom impact windows here aren’t an upgrade; they’re the standard. We field-measure each opening, verify the NOA listing for your exact configuration, and order units rated for the design pressure your structural report requires.
Geometric & Shaped Windows
Trapezoids, pentagons, octagons, clipped corners. The 1970s and 80s CBS homes in Kendale Lakes are full of them. We match the existing rough opening, confirm the NOA drawing covers the aspect ratio, and build the frame package to fit the 8-inch concrete block depth correctly. Skipping the NOA check here is exactly how wind mitigation re-inspections fail.
Arched & Curved Windows
Radius-top arches and full half-rounds are common on Kendall ranch home facades. The fabrication tolerances are tight. If the NOA drawing shows a 32-inch radius and your opening is 33, that’s a failed inspection waiting to happen. We measure to the eighth of an inch and order accordingly.
Oversized Openings
Large fixed-glass walls, full-height transoms, and multi-panel geometric arrays on Kendall acreage homes. These openings often sit on windward walls where design pressures climb fast. We size the mullions, the jamb extensions, and the anchoring per the engineering, not the other way around.

Trusted Brands We Service in Kendall
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. For Kendall custom geometric work, we lean most on PGT WinGuard, CGI, and ES Windows because their Miami-Dade NOA libraries cover the widest range of non-rectangular shapes and aspect ratios. When a Kendall homeowner needs a specific trapezoid or arch that matches the original opening, the NOA paperwork matters more than the brand name on the glass. We order direct from the manufacturer, and we handle the entire material haul from fabrication to your driveway.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Non-NOA geometric units from out-of-county suppliers. A homeowner buys an arched window from a distributor in Broward, and the unit carries a Florida Product Approval but no Miami-Dade NOA for that shape. It fails the wind mitigation re-inspection, and the insurance non-renewal stays.
- Original aluminum jalousie and single-pane sliders in 1970s CBS ranches. These windows predate post-Hurricane Andrew code reforms entirely. They don’t meet HVHZ design pressure, they leak air and water, and insurers increasingly refuse to renew policies over them.
- Oversized geometric units on windward walls bowing under negative pressure. A large trapezoid on a second-story gable gets installed without checking the design pressure for that elevation. The sash deflects, the seal breaks, and the next wind mitigation audit catches it.
- Setback and well-line conflicts on acreage lots. East of the Turnpike and in the deeper Kendall acreage zones, a new oversized window opening can run into county setback rules, septic drain field lines, or well locations. That’s a stop-work order if it’s not checked before the first cut.
Pricing for Custom & Geometric Windows in Kendall, FL
Custom geometric impact windows in Kendall run $2,500-$5,000 per opening installed, depending on shape complexity, opening size, floor height, and design pressure requirements. A standard rectangular impact window in the same market runs $800-$1,500 installed, so the custom geometry adds real cost. Each additional $500-$800 generally reflects the NOA documentation, custom fabrication, and the heavier frame engineering that non-standard shapes require. When you call us at (904) 478-8983, we’ll schedule a free in-home measure, verify the NOA listing for your exact opening, and give you a written quote before any work begins.
What Custom & Geometric Windows Costs in Kendall
Here’s the pricing structure we actually quote in Kendall:
- Standard impact windows (rectangular): $800-$1,500 per unit installed
- Impact single-hung: $900-$1,800 per unit installed
- Custom geometric or oversized openings: $2,500-$5,000 per opening installed
- Whole-home packages: $8,000-$25,000+ depending on opening count and shapes
What moves the price in Kendall specifically: the number of openings, whether the wall sits on a windward exposure with higher design pressure, the floor height of the unit, the frame material, and whether the opening is in a CBS wall that needs a jamb extension. On acreage lots east of the Turnpike, we also scope county permitting, septic and well setbacks, and the equipment access for long material hauls before quoting. No surprises on the invoice. Ever.
Florida Pays You Back
Kendall homeowners can stack several programs to offset the cost of custom impact windows. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida has a sales-tax exemption on impact-resistant windows and doors. The federal 25C energy credit can cover 30% of product cost on qualifying units, up to $600 per year. And after a wind mitigation inspection ($75-$150), many insurers apply a windstorm-premium credit averaging around 25% on the windstorm portion of the policy. Programs and carriers set the final numbers, so we don’t guarantee a figure. But the stack is real, and we help Kendall homeowners file the paperwork correctly. A Citizens non-renewal letter is often the starting point; the incentive math is what makes the job make sense.
One comparison worth making: impact windows versus hurricane shutters. Shutters cost less upfront, but someone has to put them up before every storm, and they do nothing for daily UV, noise, or energy use. Impact windows are permanent protection. No panels to hang. No plywood at 11 p.m. The glass is in the wall all year, doing its job while you sleep.
Kendall’s Permitting, Setbacks, and the NOA Matching Problem
In Kendall, every custom geometric window, from a radius-top arch to a trapezoid transom, must carry a Miami-Dade NOA listing the exact size, shape, and design pressure for that opening. One county north, the same shape can be installed with a Florida Product Approval alone. Here in the HVHZ, non-NOA geometric units can stall a wind mitigation report or fail a re-inspection entirely. That’s the single most common problem we fix for Kendall homeowners who bought a window from the wrong supplier.
Then there’s the acreage factor. Kendall has miles of larger lots where county, not city, permitting applies. Septic systems and well lines run through yards. Setbacks from property lines restrict where an opening can be enlarged. We scope all of it before we quote. We check the as-built survey, we verify septic and well locations, and we confirm the county’s setback rules for the proposed opening. If an oversized geometric window can’t go where you want it without a variance, we tell you before you spend a dollar. If grading and drainage on the open lot affect the installation, we factor that into the quote too.
We replaced nine original aluminum jalousie panels with custom impact-rated geometric windows in a Kendale Lakes CBS ranch after the homeowner’s Citizens wind mitigation inspection flagged non-rated units. Our crew field-measured each trapezoid opening, confirmed the PGT WinGuard custom arched and trapezoid units had Miami-Dade NOA coverage for the exact aspect ratios, and added a hurricane-rated jamb extension for the 8-inch CBS wall depth. The homeowner then submitted the updated NOA packet and Florida Product Approval letters to their insurer under Florida Statute 627.0629 and reinstated their policy with a windstorm credit. That’s the Kendall sequence: inspection letter, NOA match, install, reinstatement.

FAQs - Custom & Geometric Windows in Kendall
Every custom geometric window in Kendall needs a Miami-Dade NOA that lists the exact size, shape, and design pressure for that specific unit. You cannot use one NOA to cover multiple different shapes or sizes. If the opening has multiple units, each one needs its own NOA documentation that matches the as-built dimensions. This is non-negotiable in the HVHZ. Call (904) 478-8983 and we’ll verify the NOA library for your exact shapes before you order anything.
Yes, as long as the custom arch or trapezoid impact window carries a Miami-Dade NOA for the exact size and shape and is installed per the manufacturer’s anchoring schedule. The wind mitigation inspector verifies the NOA matches the unit. If it does, the credit applies the same as a standard rectangle. If it doesn’t, the inspection fails and the credit is denied. We’ve seen both outcomes. Call (904) 478-8983 for a free review of your existing NOA paperwork.
Setback, septic, and well lines can prevent the opening from being enlarged in the direction you want, or they can require the window to stay within the existing rough opening. On Kendall acreage lots, county records show the drain field and well locations. We pull those records, check the survey, and confirm the setbacks before cutting. If the window can’t go where you planned, we’ll show you alternatives that fit within county rules. Call (904) 478-8983 and we’ll scope your lot first.
Custom geometric windows count toward the impact-window discount as long as each unit carries a Miami-Dade NOA matching its exact size and shape. Citizens and other insurers don’t care whether the window is a rectangle, an arch, or a trapezoid. They care whether the NOA drawing matches the as-built unit and whether the design pressure covers the opening. Non-NOA geometric units are the ones that stall reports. Call (904) 478-8983 for a same-day review of your non-renewal letter.
Yes, you can combine a custom curved window with a standard impact-rated casement or double-hung on a Kendall CBS wall, but the jamb depth must be consistent across the mullion, and the anchoring schedule must be engineered for the assembly. CBS walls are typically 8 inches thick, and a standard 4-9/16-inch jamb needs an extension to reach the interior face. We build and install the jamb extension as part of the job. Call (904) 478-8983 for a free measure and a written quote that includes the extension.
