Fast, Reliable Custom & Geometric Windows Across Olympia Heights
Custom and geometric windows in Olympia Heights almost always mean one thing: a Miami-Dade Notice of Acceptance (NOA) is required before the county will even look at your permit. That’s not a preference, it’s code. Winslow Windows & Doors has been navigating Miami-Dade’s High Velocity Hurricane Zone rules since 2011, and we stock and order NOA-certified shaped, arched, and oversized impact windows that actually pass inspection here. Call (850) 930-1813 for a free in-home measure and a written quote built for your specific opening.
Why Winslow Windows & Doors Is Olympia Heights’s Preferred Custom & Geometric Windows Company
Ed Winslow’s name is on the door, and on every job we do. We’re not a franchise that sends whichever crew is closest that day. Every technician who arrives in Olympia Heights is background-checked, uniformed, and knows the difference between a Florida Product Approval and a Miami-Dade NOA before they step out of the truck.
We work on the 1950s through 1970s CBS ranch homes that make up most of Olympia Heights. We know the jalousie windows, the sagging lintels over arched openings, and the way afternoon thunderstorms find every flashing mistake. Our Custom & Geometric Windows team has replaced hundreds of original louvered units with impact-rated casements, picture windows, and radius arches that close Miami-Dade inspections on the first pass.
Because we’re locally owned and owner-operated, a live person answers our phone 24/7. No voicemail loop. No call center. When you call about a binding custom sash or a failed seal on an arched unit, you’ll talk to someone who knows what an HVHZ design pressure is and why it matters in Olympia Heights.
Our Custom & Geometric Windows Services in Olympia Heights
Custom Impact Windows
Every custom impact window we install in Olympia Heights carries a Miami-Dade NOA number specific to its size, shape, and design pressure rating. We’re an authorized installer for CWS, ES Windows, and ECO Window Systems, all of which offer shaped and oversized configurations with NOA documentation. The rough opening matters more than the glass. We measure, verify framing, and write the NOA number into the permit package before the unit is even ordered.

Geometric & Shaped Windows
Triangles, trapezoids, pentagons, octagons. Olympia Heights ranch homes from the 1960s and 1970s often have original fixed geometric glass in gable ends or entry features that has never been impact-rated. We replace those with laminated, NOA-certified geometric units matched to the opening’s exact angles. ES Windows and ECO Window Systems both fabricate true geometric shapes, not trimmed rectangles.

Arched & Curved Windows
Arched windows in Olympia Heights are almost always special-order, because the radius has to be fabricated to your exact opening and then certified under a Miami-Dade NOA. We handle the full sequence: template the arch, verify the lintel is sound, order the unit, reframe if the opening has sagged, and flash it for daily South Florida rain. A curved impact window with a failed flashing detail will rot the interior casing inside a year. We flash it once, correctly.

Oversized Openings
Large fixed picture windows, wide sliding glass openings, and wall-to-wall glass all require design pressure calculations matched to the opening size and your home’s location within Olympia Heights. We pull the wind-load data from Miami-Dade’s records, not a guess. Oversized custom impact openings in Olympia Heights typically run $2,500 to $5,000 per opening installed, depending on framing condition and glass package.

Trusted Brands We Service in Olympia Heights
We’re an authorized installer for CWS, ES Windows, and ECO Window Systems, three manufacturers that produce NOA-certified custom and geometric impact windows suited to Miami-Dade’s wind zone. Because Olympia Heights is a core service area, we keep common replacement hardware and seal stock close by, which means fewer return trips and faster turnaround when a sash needs adjustment or a seal fails under South Florida UV. Every unit we order for Olympia Heights is documented with its NOA number before it leaves the factory.
Common Custom & Geometric Windows Problems We See in Olympia Heights Homes
- Florida Product Approval units that aren’t NOA-certified. We regularly get calls from Olympia Heights homeowners whose contractor ordered a shaped window that passes anywhere else in Florida, but Miami-Dade rejected it at rough inspection because no NOA number was on the unit. The window has to be pulled and reordered. We check the certification before we order, not after.
- Sagging lintels over arched openings. Many 1950s CBS homes in Olympia Heights were built with undersized headers over large arched or radius openings. The lintel sags, the custom sash binds, and the laminated glass interlayer starts delaminating within two years. We inspect the header on every oversized opening and reframe when engineering requires it.
- Failed flashing on curved impact windows. Daily afternoon thunderstorms in Olympia Heights expose every flashing mistake. Water wicks into the concrete block wall, and the interior casing rots before the first-year warranty expires. Our crews use marine-grade flashing and follow Miami-Dade’s HVHZ detail drawings, not a one-size-fits-all tape job.
- Original jalousie windows with zero impact rating. The louvered glass windows common in 1960s Olympia Heights homes carry no large-missile rating and will never pass a wind-mitigation inspection. Replacing them with NOA-rated custom casements or picture windows is the single biggest upgrade you can make to both safety and windstorm premium credits.
What Custom & Geometric Windows Costs in Olympia Heights
The answer-first number: expect $800 to $1,500 per window installed for standard impact units, $900 to $1,800 for impact single-hungs, and $2,500 to $5,000 for large or custom openings. Whole-home packages in Olympia Heights typically land between $8,000 and $25,000 or more, depending on opening count, floor height, frame material, and whether framing repairs are required once walls are open.
What moves the price in Olympia Heights specifically:
- Opening count. A full jalousie-to-impact replacement on a 3-bedroom CBS ranch runs more than swapping two front-facing windows.
- Wind zone and design pressure. Olympia Heights sits in a High Velocity Hurricane Zone with design wind speeds exceeding 150 mph. Larger openings need higher design pressure ratings, which pushes the glass package cost up.
- Framing condition. Original 2×4 framing around 1960s louvered openings frequently needs to be rebuilt to carry a heavy laminated impact unit. That’s labor and lumber, written into your quote as a line item, not a surprise.
- Frame material. Aluminum, vinyl, or thermally broken aluminum all have different material costs and lead times.
We do free in-home measuring and written line-item quotes in Olympia Heights. The price we write is the price you pay. No change orders unless you approve them in writing first. Call (850) 930-1813 to schedule yours.
Pricing for Custom & Geometric Windows in Olympia Heights, FL
We quote every Olympia Heights job after measuring the actual opening, not from a photo or a guess. A standard custom impact window runs $800 to $1,500 installed. Arched and curved units typically land between $1,500 and $3,500 because the radius has to be fabricated and NOA-certified for your exact opening. Oversized openings start around $2,500 and can reach $5,000 or more when structural framing is involved. If your home still has original jalousie windows, a whole-home replacement usually falls in the $8,000 to $25,000 range. Call (850) 930-1813 for a free, written, line-item quote. No trip charge for Olympia Heights homes.
Florida Pays You Back
Olympia Heights homeowners have three incentive paths worth knowing about. My Safe Florida Home matching grants can cover up to $10,000 of qualifying wind-mitigation upgrades, including impact windows, if you qualify. Florida’s sales-tax exemption applies to impact-resistant windows and doors, so you pay no sales tax on the units. And the federal 25C energy credit returns 30% of the product cost on qualifying energy-efficient units, up to $600 per year.
After installation, a wind-mitigation inspection (typically $75 to $150) can unlock windstorm premium credits that average around 25% on the windstorm portion of your policy. We don’t guarantee what your carrier will approve. We do make sure every NOA number and installation detail is documented so the inspector has what they need. Programs change, carriers set their own numbers, but the credits are real and worth pursuing.
One more comparison worth making: impact windows versus hurricane shutters. Shutters sit in the garage until a storm approaches, and someone has to hang them. Impact windows are always in place, always protecting, and they count toward your wind-mitigation discount without any action from you. For a custom geometric opening, shutters are usually impossible to fabricate anyway. Impact glass is the only realistic path to code compliance and insurance credits on shaped openings in Olympia Heights.

FAQs - Custom & Geometric Windows in Olympia Heights
You need a Miami-Dade NOA. A Florida Product Approval sticker will not pass a Miami-Dade rough inspection for any window or door in Olympia Heights. The NOA certifies that the exact product configuration, including shape, size, glass package, and frame, has been tested to Miami-Dade’s High Velocity Hurricane Zone standards. Arched and geometric windows are almost always special-order because the NOA has to match your specific opening. Call (850) 930-1813 and we’ll verify the NOA exists for your window before we order it.
We inspect the lintel first. Many 1950s CBS ranch homes in Olympia Heights have undersized headers over large arched openings, and sagging is common. If the header is sound, we template the radius, verify the rough opening dimensions, and order the unit to match. If the framing needs work, we reframe to the design pressure required for your opening and write that work into your quote as a line item before we start. You approve every change in writing.
Custom fabrication for NOA-certified geometric and arched impact windows typically runs 4 to 6 weeks from order to delivery. Once the units arrive, installation can be completed in as fast as a single day, depending on the number of openings and framing condition. We order the window only after the permit package is clean, so you’re not paying storage fees or waiting through a reorder.
Yes. CWS, ES Windows, and ECO Window Systems all offer Low-E coatings on most arched and curved impact configurations. Low-E cuts heat gain, which matters in Olympia Heights where one o’clock sun through a west-facing window will cook a living room. Your NOA documentation will list the coating as part of the certified glass package, so you get the energy performance and the code compliance in the same unit. Call (850) 930-1813 to talk through glass packages.
It gets fixed, and you don’t pay for our mistake. The Done Right Promise means if it’s not done right, we make it right. In practice, this almost never happens on our Olympia Heights jobs because we verify the NOA number, the design pressure rating, and the installation detail against Miami-Dade’s HVHZ requirements before the inspector arrives. If something is flagged, our crew returns, corrects it, and we schedule the reinspection at our cost. That’s Ed Winslow’s name on the permit.
What Custom & Geometric Windows Cost in Olympia Heights: The Real Breakdown
Here’s the honest math, the part most companies skip. A custom impact window in Olympia Heights is not a retail window with an impact sticker. It’s a fabricated unit, NOA-certified for your specific opening, ordered after your permit is prepared, and installed to Miami-Dade’s HVHZ detail drawings. That sequence costs more than a standard replacement, and here’s what each piece of the price actually pays for.
Material costs vary by shape and glass package. A standard rectangular impact window runs $400 to $800 for the unit alone. A true arched window, fabricated to your radius, typically runs $700 to $1,400 for the unit. A large fixed geometric picture window can run $1,200 to $2,800. Installation adds $300 to $700 per opening for a standard swap, more if we’re removing jalousie frames, reframing, or rebuilding flashing. Structural work on oversized openings adds whatever the engineer specifies, and that’s the part you need allowance for, not a guess.
The opening inspection is the thing nobody does and everybody pays for later. We walk your Olympia Heights home before we quote. We check the lintels, we check the existing flashing, we look at what’s behind the interior casing. If your 1960s opening has 2×4 framing that won’t carry a laminated impact unit at a design pressure above 150 mph, we write the reframe into the quote. If the waterproofing has failed, we write that in too. You know the number before you sign. Call (850) 930-1813 to schedule your free in-home measure.
