AfterFast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric windows in Kendall almost always mean impact-rated openings that meet Miami-Dade County’s High Velocity Hurricane Zone code. That’s the starting point here, and it changes everything about how the job gets specified, permitted, and priced. A round top, an angled gable window, a trapezoid over a door: each of these has to carry a Miami-Dade NOA tied to the exact shape and glass package. We’ve been handling that paperwork and those installs in Kendall long enough that it’s second nature. Call (727) 291-4678 and Ed Winslow or a member of our team will walk you through what your opening actually needs.
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Our Custom & Geometric Windows team works Kendall neighborhoods every week, from The Hammocks down to Kendall Lakes and along the SW 88th Street corridor. We know what the windshield survey shows on block after block: CBS construction, barrel tile roofs, and a lot of aluminum frames that went in during the fast post-Andrew rebuild. That local repetition means we’re not learning your house type for the first time when we show up.
Ed Winslow put his name on this business in 2011 and never hid behind a call center. Every call to (727) 291-4678 is picked up by a person, at any hour. Every technician who steps onto a Kendall driveway is background-checked and in uniform. Those are not marketing lines. Those are how we’ve kept homeowners in Kendall calling us back for 15 years when a custom arch needs replacing or a geometric fixed unit finally gives out.
We’re not a franchise waving at you from three counties away. Scheduling for Kendall runs through our Miami office, and the crew that measures your opening is the crew that comes back to install it. Quotes are written, line-itemed, and honored. No change orders appear because we missed a measurement.
Our Custom & Geometric Windows Services in Kendall
Custom Impact Windows
Every custom impact window we order for a Kendall home starts with the shape, then the design pressure number that shape has to survive. A pentagon window on a north wall of a Kendall Lakes two-story faces different wind load than a rectangle on a protected rear elevation. We pull the Miami-Dade NOA before we order glass, not after. Expect laminated impact glass, heavy-duty frames, and a permit that actually passes the first review.
Geometric & Shaped Windows
Trapezoids, triangles, octagons, parallelograms. Kendall’s builder-era homes used these as accent pieces over entry doors and in stairwells, and many of those original units are now fogged, corroded, or leaking. We order replacement shapes cut to the manufacturer’s approved configurations for each geometry. If your existing shape was never code-approved in the first place, we’ll tell you before you spend a dollar.
Arched & Curved Windows
Arched tops are the signature feature on a lot of Kendall’s 1980s and 1990s ranch facades, and they’re the hardest opening to get right under HVHZ rules. A half-round or eyebrow unit needs a NOA that covers that exact radius, not just “similar.” We recently retrofitted a 1990s CBS ranch in The Hammocks with an oversized arched custom impact window by PGT, replacing a post-Andrew builder-grade unit that had failed wind mitigation inspection due to corroded aluminum jamb and missing NOA documentation. Our crew pulled the old frame, sized the new laminated glass interlayer to Miami-Dade HVHZ large-missile rating, and matched the HOA’s required colonial grid profile. That job cut the homeowner’s insurance premium and eliminated the salt-air rot around the sash.
Oversized Openings
When a Kendall homeowner blows out a wall for a view of the lake behind their Hammocks lot or opens a great room to the backyard, the window stops being a window and starts being a structural event. Oversized custom openings need header work, heavier mullions, and glass packages tested for large-missile impact at 175+ mph. We handle the engineering coordination and the permit, and we’ll give you a hard number before the first hammer swings.

Trusted Brands We Service in Kendall
We’re an authorized installer for PGT, CGI, among the eight premium brands our shop carries. That authorization matters in Kendall because the NOA paperwork has to match the manufacturer’s exact product line and glass make-up. We can order the right PGT arched unit or ViewLux geometric series window with the correct Miami-Dade approval, and our relationships with those manufacturers mean we get technical answers fast when an opening has unusual geometry. No endless holding patterns while a permit deadline passes.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Failed NOA documentation at permit review. A contractor from Broward installs a shape that’s fine under Florida Product Approval but has no Miami-Dade NOA for that specific geometry. The permit gets rejected or, worse, the install gets flagged after the fact and the homeowner is left uninsured for the next named storm.
- Salt-air aluminum corrosion. Kendall’s humidity and the salt drifting up Biscayne Bay and through the canal paths eat aluminum frames noticeably faster than inland. Custom shapes with tight radius corners trap moisture, and we see failed seals and pitted frames on units less than 15 years old.
- Wrong solar heat gain on curved glass. A geometric window with SHGC tuned for a northern climate spikes cooling bills in Kendall’s year-round sun. South-facing arches especially need low-SHGC glass, not whatever the catalog default is.
- HOA muntin and frame mismatches. Master-planned communities like Kendall Lakes and newer developments around SW 117th Avenue have strict architectural review standards for shaped windows. Get the grid profile or frame color wrong and you can be forced to remove a brand-new unit.
Pricing for Custom & Geometric Windows in Kendall, FL
Real numbers for real openings in Kendall. A standard replacement impact window in the area generally runs $800 to $1,500 installed. A custom geometric unit with impact glass adds fabrication and engineering, so expect $1,200 to $3,000 for most trapezoid, octagon, or angled shapes. A large arched or curved window over an entry or great room view runs $2,500 to $5,000, depending on radius, glass package, and whether the opening needs structural reinforcement. Whole-home packages in Kendall, where every opening gets replaced to meet HVHZ and satisfy insurance underwriting, fall in the $8,000 to $25,000 range and up from there depending on count and shape complexity.
What moves the price in Kendall specifically: the number of custom shapes (every non-rectangle costs more), wind-zone design pressures at your exact address, floor height on two-story elevations, and whether your HOA requires a specific grid pattern or frame finish. We give free in-home measurements, and every quote is written, line-itemed, and good from the day we hand it to you. Call (727) 291-4678 to set one up.
What Custom & Geometric Windows Costs in Kendall
Let’s anchor this in real market numbers for Kendall. Impact windows in our area run $800 to $1,500 per window installed. Impact single-hung units range $900 to $1,800. Large or custom openings, especially arched and curved shapes with HVHZ glass packages, typically land between $2,500 and $5,000. Whole-home packages for a Kendall CBS ranch or two-story run $8,000 to $25,000 and up. What moves the price: opening count, how many are non-rectangular, the wind-zone designation at your block, floor height, and frame material (vinyl runs lower than thermally broken aluminum, which you’ll want for large spans). We measure in person at no charge and put every number in writing before you commit.

Florida Pays You Back
The incentive math in Kendall gets better every year because the insurance pressure is so high. My Safe Florida Home matching grants can cover up to $10,000 on qualifying wind-mitigation upgrades for eligible homeowners. Florida’s sales-tax exemption applies to impact-resistant windows and doors, which means the product portion of your custom geometric window is taxed at zero percent. The federal 25C energy credit returns 30% of product cost, up to $600 per year on qualifying units. And after a wind mitigation inspection (typically $75 to $150), most Kendall homeowners see windstorm-premium credits averaging around 25% on the wind portion of their policy. The carrier sets the final number, and we never promise a specific dollar figure on your premium. But the direction is close to universal: install NOA-compliant impact openings, pay less on insurance every year after.
Impact windows also beat hurricane shutters for the Kendall homeowner who’s tired of hauling steel panels out of the garage at 11 p.m. while a storm warning blares. Permanent protection. No panels to find, lift, and hang. That’s the comparison we hear most from homeowners who’ve done both.

FAQs - Custom & Geometric Windows in Kendall
Short answer: in most Kendall communities, you need both. Miami-Dade County requires the permit and the NOA. The HOA’s architectural review is a separate requirement, and communities like Kendall Lakes and the newer subdivisions around SW 117th Avenue enforce it aggressively. A shaped window that differs from the approved muntin pattern, frame color, or glass tint can get flagged. Pull the HOA guidelines for your section before you order anything. We handle the permit paperwork and can even sit in on the HOA review if your board allows it. Call (727) 291-4678 and we’ll check your community’s standards with you.
Yes, a single-opening replacement does not by itself force a whole-house retrofit. What it does is add one more compliant opening to your wind mitigation report, which may or may not move your insurance credit. The bigger question is whether your other openings are still original post-Andrew units. If they are, replacing just one arch leaves the others vulnerable, and your carrier may still withhold the mitigation discount until a threshold percentage of openings are impact-rated. We’ll tell you what your report currently shows and what one window changes.
Because Fort Lauderdale sits in Broward County, where a Florida Product Approval satisfies code, while Kendall sits in Miami-Dade County’s High Velocity Hurricane Zone, where every window and door must carry a separate Miami-Dade County Notice of Acceptance (NOA). The NOA is tied to the county’s 175+ mph design pressure requirements and is shape-specific: a NOA for a rectangle does not cover an arch or a trapezoid. Contractors who work mostly outside Miami-Dade often don’t carry the right certifications and get caught at permit review. That rejection isn’t a formality. It means your window is not code-compliant in Kendall and would leave you uninsured after a storm. We verify the NOA before we order glass, every time.
Not automatically. Each geometry gets its own design pressure rating, and the values shift with size, aspect ratio, and even which direction the wall faces. An octagon, a half-round, a tall trapezoid: each shape has a different wind-load profile. Manufacturers publish NOA documents that pair a specific geometry with a specific tested pressure. What works for a 24-by-48 rectangle might not hold for a 60-inch arch. We pull the specific NOA for your exact shape and elevation before ordering. That’s standard practice for us, and it’s the only way a Kendall permit lands clean the first time.
Replacing a window in a newly built Kendall home does not automatically void your builder’s structural warranty, but it can if the work damages the surrounding wall system, flashing, or stucco. The key is documentation: keep the permit record, the NOA for the new unit, and any HOA approval in writing. If the builder’s warranty has a clause about third-party modifications, get the replacement noted in writing before installation. We’ve done this enough in Kendall’s newer subdivisions that we know which builders require what. We’ll walk you through it before the first cut.
