Fast, Reliable Custom & Geometric Windows Across Kendall
Custom geometric windows in Kendall are not an off-the-shelf purchase. Every arched, radius, circular, or oversized opening must be engineered to Miami-Dade HVHZ design pressures that routinely exceed ±70 psf on a two-story home, and it must carry a Miami-Dade County Notice of Acceptance (NOA) before a permit gets issued. That single fact changes everything about how we specify, order, and install these windows in Kendall. Winslow Windows & Doors has handled this regulatory layer for local homeowners since 2011, and when you call (239) 310-4121, you’ll reach a live person who knows exactly what Kendall’s building department will ask for.
We measure, engineer, and install Custom & Geometric Windows across Kendall, from Country Walk to Calusa and everything in between. Ed Winslow’s name is on the door, and every job we run through Kendall gets his direct attention from quote to final inspection.
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Kendall homeowners tend to be research-heavy buyers. They know their home sits inside the High Velocity Hurricane Zone, and they’ve learned to ask about NOAs, design pressure labels, and large-missile test compliance before they talk price. That’s the conversation we’re built for. Our team walks every Kendall job with the approved anchorage schedule in hand, because we know a Miami-Dade inspector will check the label on the frame and the fasteners behind it.
We answer the phone 24/7. No call center, no voicemail loop at 2 a.m. when a failed arched transom has water coming into your foyer during a storm. Our technicians arrive in uniform, background-checked, and they’ll know your subdivision’s HOA rules before they unload the ladder. Kendall has dozens of master-planned communities with architectural review committees, and we’ve worked through enough of them to anticipate what gets rejected and why.
The Done Right Promise applies to every custom geometric window we install in Kendall. If it’s not done right, we make it right. That’s not a warranty card in a drawer; that’s Ed Winslow’s standing rule for his own company.
Our Custom & Geometric Windows Services in Kendall
Custom Impact Windows
Custom impact windows in Kendall run $1,200 to $3,800 per opening depending on shape and glass package. Every unit we install carries a Miami-Dade NOA and passes the Large Missile Impact test rating for your specific wind zone. We’ve replaced countless builder-grade rectangles in the newer sections of Kendall with true impact-rated units that cut windstorm premiums and stop water intrusion.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, and angled bays are common across Kendall’s newer developments, especially in master-planned communities like Three Lakes and The Crossings. These shapes cannot be pulled from stock. Each one gets templated, engineered to the opening’s design pressure, and fabricated to order. Expect 4 to 6 weeks for fabrication and a one-day install once the unit lands.

Arched & Curved Windows
Arched and curved impact frames in Kendall oxidize fast. Salt-laden air pushed inland from Biscayne Bay, humidity above 80%, and year-round UV exposure take 5 to 7 years off an aluminum radius frame compared to inland Florida. We carry NOA-tested arched units from CWS and Mr-Glass, and we re-flash and reset jambs instead of caulking over corrosion. That’s the difference between a 10-year window and a 2-year callback.

Oversized Openings
Large fixed picture windows and sliding glass walls spanning 8 to 16 feet are common in Kendall’s post-Andrew rebuilds. Many of those openings were under-specified when they went in 25 to 30 years ago. Today’s wind-mitigation loads often require structural re-engineering and custom NOA-tested frames before we can drop a new unit in. We handle the engineering coordination directly, so you don’t chase a structural engineer across Miami-Dade.

Trusted Brands We Service in Kendall
Winslow is an authorized installer for PGT, Mr-Glass, among others, and Kendall homeowners get full factory warranty support through our account. When you call about a binding radius sash or a fogged geometric unit, we don’t have to call a distributor and wait three days for a part number. We stock common NOA-tested hardware locally and can usually diagnose and quote the same week. For full frame replacements on custom shapes, we order directly from the manufacturer with the exact Miami-Dade NOA config matching your opening.
Common Custom & Geometric Windows Problems We See in Kendall Homes
- Oxidized arched frames and binding sashes. Salt air eats aluminum radius frames in 5 to 7 years. The sash swells, binds against the jamb, and eventually the crank mechanism strips. We see this constantly around the Country Walk and West Kendall areas.
- Failed NOA compliance on DIY or handyman installs. A custom geometric window installed without the exact approved anchorage schedule loses its NOA validity. The inspector flags it, and the whole unit gets torn out and redone. We fix several of these a year in Kendall.
- Builder-grade geometric windows with no impact rating. Many 2010s-era Kendall townhomes went in with decorative arched transoms that are single-pane and non-impact. They look nice until a storm is 48 hours out, then the homeowner realizes there’s no protection and no insurance credit.
- Water intrusion around custom shapes. Angled bays and radius transoms have more seam footage than rectangles. Bad flashing from the original build shows up as staining on drywall and mold on the sill. We pull the unit, re-flash the rough opening, and reset the window properly.
Pricing for Custom & Geometric Windows in Kendall, FL
Here’s what we quote in Kendall: a standard custom impact window runs $800 to $1,500 per window installed. A single-hung impact unit goes $900 to $1,800. Large or custom geometric openings start at $2,500 and run to $5,000. Whole-home packages in Kendall run $8,000 to $25,000 and up, depending on opening count, floor height, and frame material. A two-story home on a zero-lot-line lot in The Hammocks carries higher design pressures than a one-story in Calusa, and that moves the engineering and frame spec. We give one written, line-item quote with no change orders, and the estimate is free. Call (239) 310-4121 to schedule yours.
What Custom & Geometric Windows Costs in Kendall
Let’s break the cost drivers down, because Kendall has a few that don’t apply anywhere else in Florida. Opening count is the obvious one, but wind zone and floor height matter just as much. A two-story opening on a Kendall home can require a design pressure of ±70 psf or more, which forces a heavier frame and thicker laminated glass than the same window would need in, say, Central Florida. That’s not upsell; that’s code. Frame material is the third driver. Aluminum is the standard in Kendall’s salt-laden air, but premium NOA-tested radius frames from Mr-Glass or ViewLux carry a higher unit cost than stock vinyl. We measure every opening at your home, pull the exact Florida Product Approval and Miami-Dade NOA for the configuration, and hand you a written quote. Call (239) 310-4121 for a free in-home measure.
| Kendall Custom Window Type | Typical Installed Range |

Florida Pays You Back
Kendall homeowners can stack several programs to offset the cost of custom impact windows. My Safe Florida Home matching grants reach up to $10,000 for qualifying wind-mitigation upgrades, though the program reopens periodically and funding moves fast. Florida’s sales-tax exemption applies to impact-resistant windows and doors. The federal 25C energy credit covers 30% of product cost, up to $600 per year on qualifying units. Most homeowners in Kendall also see windstorm-premium credits averaging around 25% on the windstorm portion of their policy after a wind-mitigation inspection, which runs $75 to $150. Programs and carriers set the final numbers, so we’ll point you to the current rules and let your insurer confirm the rest. One thing worth knowing: impact windows beat hurricane shutters for most Kendall homeowners because there is nothing to haul out of the garage and hang at 11 p.m. when a storm warning hits, and the protection is always on the home.

FAQs - Custom & Geometric Windows in Kendall
Yes, you can, but the opening almost always requires structural reinforcement and a custom NOA-tested frame. Homes built before 1992 in Kendall, particularly those that survived Hurricane Andrew, often have rough openings that were framed for single-pane decorative glass, not for a laminated impact unit rated to ±70 psf. We template the opening, coordinate the engineering, and order the unit with a Miami-Dade NOA matching the reinforced rough opening. Call (239) 310-4121 and we’ll tell you what your opening can actually take.
It can, if the installation doesn’t follow the builder’s specification or HOA architectural rules. Most Kendall townhome builders have a structural and envelope warranty that stays intact when a licensed contractor pulls permits and installs to the original NOA or an upgraded Miami-Dade NOA. The risk comes when a handyman caulks a new unit into the old frame without inspections. We pull permits on every Kendall job and document the install so your builder warranty isn’t jeopardized. Call (239) 310-4121 for a free second opinion on any written estimate you’ve received.
The cost difference in Kendall comes down to engineering and fabrication. A standard double-hung is a stocked size with a pre-approved NOA. A geometric window is templated to your exact opening, engineered to the design pressure at that elevation, and fabricated as a one-off unit. Kendall’s HVHZ wind zone adds another layer, because the frame and glass must pass Large Missile Impact testing at pressures that standard Florida windows can’t meet. You’re paying for a custom-engineered product, not a marked-up stock window. Call (239) 310-4121 for a line-item quote on your specific opening.
Most Kendall HOAs approve custom geometric windows when the replacement matches the original design character and meets or exceeds the existing impact rating. The rejections we see come from homeowners who submit a different shape, a different frame color, or a non-impact unit to cut cost. We help Kendall homeowners prepare ARC submissions with the NOA, the finish schedule, and the installation scope, which answers most review board questions before they’re asked. If your ARC has concerns, call (239) 310-4121 and we’ll help you address them.
Yes, in most cases they are. Pull a permit for a custom window addition or adjacent renovation in a pre-Andrew Kendall home and the inspector will often flag existing jalousie openings, because louvered glass panels provide essentially zero large-missile impact protection under Miami-Dade code. You typically have to convert those openings to impact-rated units as part of the permit scope. We’ve handled this on dozens of Kendall homes and we’ll tell you upfront if your jalousies are likely to get flagged. Call (239) 310-4121 for a free assessment.
Kendall’s HVHZ Reality: Why Style Isn’t the Only Decision
Every custom geometric window we install in Kendall has to satisfy two masters: the look you want and the Miami-Dade building code that says no. Design pressures on a two-story Kendall home can exceed ±70 psf. That means an arched transom over your entry, a circular feature window in a stairwell, or a 12-foot fixed picture window in a great room must be engineered and tested as a system, not just fabricated to size. The NOA number attached to each unit is specific to the frame, the glass, the anchorage, and the mullion configuration. Change one element and the NOA is invalid. This is why you can’t order an arched impact window from a big-box catalog and expect it to pass a Kendall inspection. It won’t.
The practical result is that style decisions in Kendall get filtered through engineering first. Want a true radius top on a 6-foot-wide window? We can do it, with an NOA-tested Mr-Glass or CWS frame. Want a circular window in a pre-1992 home? The rough opening gets reinforced and re-flashed before the unit goes in. We handle that engineering coordination in-house, with Ed Winslow personally walking every Kendall job before the first fastener goes in.
On a 1990s two-story home in the Country Walk subdivision, our crew replaced a failed single-pane arched transom over the entry with a CWS custom radius window carrying a Miami-Dade NOA and laminated glass interlayer. The jamb had oxidized from twenty years of salt-laden air, and the original frame had no wind-mitigation capacity. We re-flashed the rough opening, reset the jamb, and installed the new sash with a design pressure label visible for the inspector. That’s what a proper Kendall install looks like.
The One Down the Road
Kendall isn’t a market we parachute into. We know the subdivisions, the older tract housing stock along Kendall Drive and Sunset Drive, the post-Andrew rebuilds, and the newer master-planned communities where architectural review committees watch every curb-facing window. We know that a geometric window on the north side of your house gets hammered by afternoon sun for six months of the year. We know the salt air off Biscayne Bay shows up faster in The Hammocks than in Calusa. And we know the inspectors, the permit office, and the NOA paperwork like the back of our hands. That’s the difference between a contractor who shows up and a neighbor you can call at 2 a.m. and someone will actually answer.
