Fast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric windows in Kendall cost between $2,500 and $5,000 per opening when impact-rated and sized for Miami-Dade’s HVHZ, and the biggest factor isn’t the glass. It’s whether the exact shape and size you want carries a current Miami-Dade Notice of Acceptance (NOA). Without one, your inspection fails and the window comes back out. Winslow Windows & Doors has been installing code-compliant Impact Windows in Kendall in the Hammocks, Kendale Lakes, and The Crossings subdivisions since 2011, and Ed Winslow’s name is on every quote. Call (850) 721-1218 for a free in-home measure and a written line-item price before you commit to anything.
What separates a good Kendall window job from a tear-out disaster is product approval paperwork. We check the Miami-Dade product approval database before we quote any custom shape, because we’ve seen inspectors reject windows in Kendall that passed rough-in in Broward the week before. That’s not a hypothetical. It’s how Miami-Dade works.
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Kendall sits in the path Hurricane Andrew cut through Miami-Dade in 1992, and much of the housing stock was rebuilt in the years immediately after. Those first-generation impact windows, installed when codes were newer and product approvals were looser, are now 25 to 30 years old. Their laminated interlayers delaminate, their radius jamb gaskets dry-rot in Kendall’s humidity, and homeowners don’t know until a claim gets denied. We do know, because we replace them. Our Custom & Geometric Windows team works on this specific end-of-life wave every week.
Ed founded Winslow in 2011 as a local alternative to the national chains that hand you a ticket number and a vague phone tree. Our published address and license number are on every quote. Every technician who rolls into a Kendall driveway is background-checked and in uniform, so you know exactly who’s at your door before the truck stops. And when you call at 2 a.m. with a storm bearing down, a live person answers. Not a voicemail loop. Not a call center. A person.
We hold authorized installer status for ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, among others, and we keep a running list of NOA-approved SKUs for the custom shapes Kendall homeowners actually ask for: arches, radius tops, ovals, trapezoids, and oversized rectangles that need design pressures matched to the opening, not pulled off a shelf. We also install Shingle, Tile & Metal Roofing - Kendall.
Our Custom & Geometric Windows Services in Kendall
Custom Impact Windows
Every custom impact window we install in Kendall carries a Miami-Dade NOA for the exact product line and size. That’s not optional, and it’s not something we negotiate. Kendall is in the High Velocity Hurricane Zone, which means any window we install has to survive sustained winds beyond 130 mph and pass large-missile impact testing. A standard impact window that’s legal in most of Florida is often not legal here. We quote only what’s approved for Miami-Dade, and we put the NOA number on your written estimate so you can verify it yourself.

Geometric & Shaped Windows
Trapezoids, triangles, pentagons, and angled units are the shapes Kendall’s mid-century and late-century homes lean on for visual interest, especially over entries and stairwells. The problem is that the same shape framed in aluminum today won’t pass HVHZ design pressure requirements without a reinforced frame and laminated glass. We order these units from manufacturers who test each configuration, not just each product line. That’s the difference between a window that passes inspection and one an inspector orders removed at rough-in.

Arched & Curved Windows
In The Crossings, our crew replaced a 1994 post-Andrew radius window over a front entry with a custom arched impact unit whose laminated glass interlayer and reinforced jamb met current HVHZ design pressure for that exact opening. We pulled the Miami-Dade NOA before quoting, scheduled rough-in and final inspections back-to-back, and confirmed the homeowner received a wind mitigation credit under Florida Statute 627.0629. Arched units fail at the radius jamb and sash joints first, and post-Andrew caulking in Kendall heat gives out faster than the glass does. We build it right the first time, and the Done Right Promise means if it isn’t right, we come back.

Oversized Openings
Oversized custom windows in Kendall’s concrete block homes need more than a bigger piece of glass. They need a header and lintel evaluation, because many original openings in 1970s and 1980s CBS construction weren’t framed for the weight of a modern impact unit. We check the structure before we order the window. When you’re putting in a ten-foot-wide fixed impact window in a Kendale Lakes living room, the framing matters as much as the glass rating, and we won’t cut corners on either.

Trusted Brands We Service in Kendall
We install and service custom and geometric windows from ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, and we keep local inventory for the parts Kendall homeowners need most: replacement gaskets, radius jamb seals, and laminated glass units sized to the common custom openings in Kendall’s original housing stock. If you have one failing arched impact window and a big-box chain tells you the whole opening needs replacing, call us instead. We’ll tell you honestly whether a sash rebuild beats a full replacement, and we’ll price both options with a written quote. That’s the difference between a parts counter and a neighbor who installs what he sells.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Radius jamb and sash joint failure. Post-Andrew-era caulking and gaskets on custom arches dry-rot in Kendall’s humidity within a decade. We see units from the mid-1990s with gaps you can slide a credit card through, air and water getting past the seal, and the homeowner believing the window is still impact-rated.
- Delaminated laminated glass interlayers. Years of afternoon sun and sea air break down the interlayer on older impact glass. The window looks fine from inside. It no longer passes large-missile testing. We test these during every replacement quote.
- NOA-missing custom shapes. This is the expensive one. A contractor quotes a shape that lacks Miami-Dade product approval. Rough-in inspection happens. The inspector rejects the unit and orders removal. The opening sits boarded for weeks while the homeowner waits on a product that was never legal here. Always ask for the NOA number on the quote before you sign.
- Oversized openings on undersized framing. A heavy custom impact unit hung on an original 1970s header can sag, crack the stucco, and compromise the seal. We inspect the opening structure before we order the window, and we pull permits on every install.
Pricing for Custom & Geometric Windows in Kendall, FL
A custom geometric impact window in Kendall typically runs $2,500 to $5,000 per opening installed. Standard rectangular impact windows run $800 to $1,500 per opening. What moves the number in Kendall is the shape complexity, the wind zone requirement, floor height above grade, the frame material you choose, and whether the opening needs structural work before the window goes in. Whole-home packages with multiple custom openings in a larger Kendall CBS home can reach $8,000 to $25,000 or more. We give you a fixed written quote with the NOA number and design pressure for every opening, so the price on the estimate is the price on the invoice. No change orders. No vague hourly charges. Call (850) 721-1218 to schedule your free in-home measure and written quote.
What Custom & Geometric Windows Costs in Kendall
Here’s the honest spread for the Kendall market. Impact windows generally run $800 to $1,500 per window installed, and a standard impact single-hung lands between $900 and $1,800. Custom or large openings jump to $2,500 to $5,000 per unit because the glass is cut to specification, the frame is reinforced for the shape, and the NOA paperwork is configuration-specific. Whole-home packages in Kendall’s larger lots typically fall between $8,000 and $25,000 or more, depending on the number of openings and how many are custom shapes. What moves the price here: opening count, the wind zone your street sits in, floor height above grade on second-story installs, and frame material. Aluminum is less expensive up front. Vinyl holds finish color longer. Impact-rated laminated glass is non-negotiable in Kendall. We do free in-home measures and hand you a written quote with every cost line itemized before any work starts.
Florida Pays You Back
Kendall homeowners can stack several programs to offset custom impact window costs. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows and doors qualify when the home passes the required inspection. Florida also exempts impact-resistant windows and doors from sales tax. At the federal level, the 25C energy credit returns 30% of product cost, up to $600 per year, on qualifying efficient units. And once your wind-mitigation inspection comes back clean, which runs about $75 to $150, you can expect your windstorm premium to drop by roughly 25% on average. Programs and carriers set the final numbers, so we never promise a specific dollar figure. We do give you the documentation your insurer and the grant program need, including the NOA numbers and the inspection sign-offs.
One comparison worth knowing: impact windows versus hurricane shutters. Shutters are cheaper up front, but you hang them every time a storm threatens, and they do nothing for energy efficiency or daily light. A custom impact window is permanent protection built into the wall. In Kendall, where storm prep is not a once-a-year inconvenience but a way of life from June through November, the window usually wins.

FAQs - Custom & Geometric Windows in Kendall
Every custom geometric window installed in Kendall must carry a Miami-Dade Notice of Acceptance that covers the exact product line, size, and configuration for your opening. A quote that doesn’t list the NOA number for each unit is a red flag. Ask for it in writing before you sign, and you can look the number up yourself in Miami-Dade’s product approval database. We include it on every estimate. Call (850) 721-1218 if you want us to review a quote you’ve already received.
Only if the specific window carries a Miami-Dade NOA. Broward County product approvals are not automatically valid in Miami-Dade’s HVHZ, and inspectors enforce this at the rough-in stage. A window that passed in Hollywood or Pembroke Pines can be ordered removed in Kendall. Before you buy from any supplier outside the county, ask for the Miami-Dade NOA number, not a Florida Product Approval, and verify it covers your exact shape and size.
Yes, when it carries the proper NOA and passes the wind mitigation inspection. The credit is based on the protection level of the opening, not the shape of the glass. An arched impact window with a documented NOA and correct design pressure qualifies the same way a rectangle does. We give you the paperwork to prove compliance to your insurer.
Because the units installed in the post-Andrew rebuild, roughly 1994 through 1997, are hitting 25 to 30 years old all at once. Their laminated glass interlayers are delaminating from years of Kendall sun and sea air, and their radius jamb seals and gaskets have dried out in the humidity. The housing stock is aging on the same timeline, which is why we’re replacing entire generations of these windows across the Hammocks and the surrounding subdivisions right now.
Every replacement window in Kendall requires a permit, a rough-in inspection before the window is covered, and a final inspection after installation. At both stages the inspector can ask for the NOA for the exact unit installed. If the number isn’t on file, the inspector orders removal, the opening gets boarded, and you wait weeks for a compliant window while the failed one sits on the curb. A clean install doesn’t skip these steps. It makes them routine.
