AfterFast, Reliable Custom & Geometric Windows Across Kendall
Custom and geometric window work in Kendall almost always means one thing: Miami-Dade County’s High Velocity Hurricane Zone rules apply, and they apply differently here than anywhere else in the country. A trapezoid over the entry on a 1980s ranch off Kendall Drive, a radius arch on a Dadeland-area CBS two-story, a full-wall glass gable on a horse-property workshop near the Redland edge; every one of those openings has to carry an active Miami-Dade Notice of Acceptance, not just a Florida Product Approval sticker. Winslow Windows & Doors has been navigating that exact paperwork trail since 2011. We know which NOA numbers clear Kendall inspections and which ones get bounced. Call (727) 620-6983 and you’ll get Ed Winslow or a member of our team on the line, not a voicemail tree.
Why Winslow Windows & Doors Is Kendall’s Preferred Custom & Geometric Windows Company
Kendall homeowners have a long memory when it comes to window work. Hurricane Andrew tore through this community in 1992, and plenty of the surviving split-levels and ranch homes still carry the original aluminum single-pane windows that predate modern HVHZ code. When we quote a replacement on an older home near West Kendall Regional Library or along Bird Road, we’re not reading from a national sales script. We know the county inspector will verify the NOA approval number, edition date, and anchor pattern on site. We build the quote around that reality from day one.
Our Custom & Geometric Windows team has worked openings that big-box retailers won’t touch: clipped corners under a barrel-tile roof, oversize radius units on concrete block walls, transoms that have to hold a Category 5 pressure rating while looking like an architectural afterthought. Ed Winslow put his name on this company, and Ed’s name is on the door, and on every job we do. The Done Right Promise means exactly what it sounds like: if it’s not done right, we make it right. That’s a century of accountability no faceless chain can match, and it’s the standard we’ve held since 2011.
Calls get answered by a live person, 24 hours a day. Every technician who pulls up to your Kendall home is background-checked and in uniform, so you know exactly who’s walking up the driveway before the truck even stops. We don’t play games with pricing either. Upfront quotes, written line items, and a free second opinion on any written estimate you bring us.
Our Custom & Geometric Windows Services in Kendall
Here’s what we actually do for Kendall homes, with the specifics that matter in this county.
Custom Impact Windows
Kendall sits fully inside the HVHZ, which means every replacement window must carry an active Miami-Dade County NOA. That’s a stricter product-approval standard than the Florida Product Approval system used in Broward and most of the state. We spec PGT, CGI, ECO Window Systems units with NOA numbers that match the exact configuration, anchor schedule, and design pressure your opening requires. A typical custom impact window on a Kendall block home runs $800 to $1,500 installed, and we’ll pull the Miami-Dade permit and schedule the inspection ourselves.
Geometric & Shaped Windows
Triangles, trapezoids, pentagons, octagons over a front entry; Kendall’s sprawling ranch homes from the 1970s and 1980s love a geometric accent window above a door or in a gable. Those openings were never built for off-the-shelf rectangles, and retrofitting an impact-rated shape onto a pre-Andrew CBS wall takes real engineering. We measure the actual rough opening, check the existing header and jamb reinforcement, and order to the sixteenth of an inch. Then we anchor it to the substrate the way the NOA drawing says, not the way some out-of-county crew guesses.
Arched & Curved Windows
On a 1980s CBS ranch off SW 104th Street near Killian Drive, our crew replaced a cracked arched window over the entry with a custom-radius PGT impact unit. We pulled the Miami-Dade County permit, matched the NOA anchor pattern to the existing block, and re-flashed the jamb to handle the open-lot drainage slope before the county inspector arrived. That’s the difference between a window that passes inspection and one that fails twice. Curved and radius work in Kendall runs $2,500 to $5,000 per opening on the high end, and for good reason: these aren’t stock units and the fabrication lead time is four to six weeks.
Oversized Openings
If you’re building a detached workshop, an ADU, or a horse barn with a glass wall on Kendall acreage, you’re dealing with openings that eat standard sizing for breakfast. We engineer these for HVHZ wind-load requirements at full design pressure, sized to the actual opening dimensions and anchored to CBS or steel framing per the NOA. Large custom impact openings run $2,500 to $5,000 and up depending on square footage and frame material, and we scope the header, jamb reinforcement, and drainage before we ever hand you a number.

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 and geometric work, we typically recommend ECO Window Systems for shaped and arched units, and Therma-Tru for entry systems that pair with geometric transoms. Because we stock replacement hardware and service parts for these brands locally, we can turn around warranty and repair calls on Kendall homes faster than a contractor who has to order everything from a distributor in Fort Lauderdale. Your window doesn’t sit boarded up for a month while someone waits on a freight shipment.
Common Custom & Geometric Windows Problems We See in Kendall Homes
These are the failure modes we see again and again on Kendall properties, and they’re specific to this county and this housing stock.
- NOA mismatch on spec’d units: A homeowner or out-of-county contractor specifies a geometric impact window from a Florida Product Approval-only catalog. The Miami-Dade inspector shows up, checks the NOA database, and rejects it for lacking an active NOA and matching anchor schedule. The window is already fabricated. Now it’s scrap. We check the NOA before we order, every time.
- Undersized headers on pre-Andrew CBS walls: Oversized arched openings on 1970s and 1980s concrete block often have headers that were adequate for the original jalousie or single-pane aluminum window but have no business carrying an impact-rated unit at HVHZ design pressure. Undersizing the header or jamb reinforcement leads to racking under wind load. We scope the structural retrofit before quoting, not after the wall starts moving.
- Septic and well setback violations on ADU or workshop windows: Adding a window to a detached structure on Kendall acreage isn’t just about the wall. Miami-Dade County reviews the permit against septic tank and well setback requirements. We’ve seen jobs get flagged for a window encroaching on a drain-field separation, forcing a re-permit and repositioning after county review. We check the setbacks before we draw the opening.
- Drainage and flashing failures on open-lot properties: A lot of Kendall acreage drains slowly, especially on the westward open lots where the grade is subtle. A window jamb that doesn’t shed water properly becomes a mold and rot problem inside two hurricane seasons. We re-flash and re-seal every opening we touch, and we do it to handle the slope we actually see on your lot, not a generic detail from a catalog.
Pricing for Custom & Geometric Windows in Kendall, FL
A custom geometric impact window in Kendall runs $800 to $1,500 per opening for straightforward shapes at standard sizes, with arched and curved units landing between $2,500 and $5,000 depending on radius and frame material. Whole-home packages on a typical Kendall ranch start around $8,000 and climb past $25,000 for larger homes with multiple shaped openings or oversized glass. The variables that move the number in Kendall specifically: opening count, whether the wall is CBS or wood frame, floor height (second-story work costs more for staging), and whether the existing header needs structural upgrading to carry HVHZ pressure. We give you a written line-item quote after a free in-home measure, and that quote doesn’t change once work starts. Call (727) 620-6983 to schedule yours.
What Custom & Geometric Windows Costs in Kendall
Let’s be straight about numbers. Impact windows in Kendall generally run $800 to $1,500 per window installed. Impact single-hung units fall between $900 and $1,800. Large or custom openings, the kind we’re usually quoting on geometric and arched work, run $2,500 to $5,000 and can go higher depending on square footage. Whole-home packages for a typical Kendall ranch or two-story start at $8,000 and top $25,000 for bigger jobs. What moves the price here more than anything: the Miami-Dade NOA requirement means you can’t buy a cheap Florida Product Approval-only unit and slip it through, and the county inspector checks. You’re paying for a product that’s engineered and documented for this wind zone, plus a labor crew that anchors it exactly to the NOA drawing. We’ll come out, measure every opening, and hand you a written quote. The measure and quote are free. No pressure, no vague “we’ll figure it out later” numbers.
Florida Pays You Back
These incentives stack, and we’ll help you understand which ones apply to your Kendall property. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows qualify. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit covers 30% of product cost up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75 to $150), most homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. Exact numbers are set by your carrier and the program administrators, so we won’t quote you a savings figure as a promise. What we will do is give you the documentation you need to file for every credit and grant you’re eligible for.
One comparison worth making before you decide: impact windows versus hurricane shutters. Shutters mean panels in a shed, a ladder in the dark, and a scramble when the warning hits. Impact windows are always on; when a storm comes through Kendall, you’re already protected, no panels to hang, no glass to tape. That’s a real difference in a county where the wind zone doesn’t cut anyone slack.
On ratings: every unit we install in Kendall carries a Miami-Dade NOA number and edition date that matches the exact configuration on your opening. Design pressures are matched to the opening, and we never install a unit rated beyond what the manufacturer’s NOA documents support. That’s true for a simple single-hung replacement and for a full-wall geometric glass wall on a new ADU. County inspectors verify the number on site, and so do we, before the window ever leaves the shop.

FAQs - Custom & Geometric Windows in Kendall
A Miami-Dade NOA is mandatory in Kendall. The entire unincorporated county falls inside the HVHZ, and county inspectors verify the NOA approval number and edition date on the window and the anchor pattern in the wall. A Florida Product Approval alone will get rejected on inspection. If you’re specing a window and someone tells you otherwise, call (727) 620-6983 before you spend a dollar. Estimates are free.
Miami-Dade County reviews window permits on detached structures against the recorded septic tank and well locations and required separation distances. A window that encroaches on a drain-field setback gets flagged at review, and you’ll have to re-permit and reposition the opening. We check the property survey and county records for setbacks before we finalize window placement, so you don’t eat a re-permit cost. Call for a free measure and we’ll scope it properly.
The header and jamb condition. Pre-Andrew CBS walls often have headers that were sized for the original single-pane aluminum or jalousie window and can’t carry an impact-rated arched unit at HVHZ design pressure. Structural reinforcement adds labor and material cost before the window even goes in. After that, the radius and frame material move the number. A custom arched impact unit on a block Kendall home runs $2,500 to $5,000 installed, and we’ll show you the line items before you sign anything. Call (727) 620-6983 for a written quote.
You can, and in a lot of cases you should. Modern low-iron Low-E laminates are much clearer than the blue-green tint people remember from the 1990s, especially in shaped and oversized openings where you want the view to stay true. The right glass package cuts the UV load without turning your archway into a tinted windshield. We’ll show you glass samples in natural light before you commit so there are no surprises after the window goes in. Call for a free estimate and we’ll bring the samples to your home.
Open lots drain slowly, and window jambs on outbuildings catch water that has nowhere to go fast. We re-flash and re-seal every opening to handle the actual grade slope on your property, not a generic detail from a manual. On that CBS ranch off SW 104th Street, the new arched unit over the entry got its jamb re-flashed to handle the drainage slope before the county inspector arrived. It’s a small step that prevents rot and mold inside two hurricane seasons. Call (727) 620-6983 to get yours done right.
