Fast, Reliable Custom & Geometric Windows Across Olympia Heights
Custom and geometric windows in Olympia Heights aren’t a side project for us. They’re one of the reasons Ed Winslow started this company in 2011, and they’re a job we take seriously because this neighborhood punishes shortcuts. If you need an arched transom, an octagon accent window, or an oversized impact-rated picture unit for a mid-century CBS ranch, call (727) 620-6983. We’ll send a background-checked, uniformed technician to measure, assess the wall, and give you a written line-item quote before you spend a dime.
Olympia Heights sits square in Miami-Dade County’s High Velocity Hurricane Zone, so every custom window we install here has to do two jobs at once: look exactly the way you want it to, and survive what the county says it has to survive. That combination filters out a lot of installers. It’s also the reason our team’s familiarity with this neighborhood’s specific housing stock matters. We know the 1950s and 1960s block homes along Southwest 40th Street and the streets branching off Southwest 97th Avenue. We know the rough openings usually aren’t square, the block isn’t always plumb, and the original jalousie frames left nobody any room for error.
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. That’s not a slogan. When a homeowner in Olympia Heights calls us, they get a live person on the phone, not a voicemail tree, not a call center. Our technicians arrive in uniform, background-checked, and carrying the brand-exact parts needed for your opening. We don’t subcontract the work to a crew we’ve never met.
Homeowners here have every reason to be skeptical. They’ve watched other contractors fumble the permit process on HVHZ-listed openings. They’ve had rough quotes that turned into change orders once the wall was open. Our approach is different: fixed pricing from the start, a published address, a published license number, and the Done Right Promise. If it’s not done right, we make it right, period. That promise means something specific on a custom geometric install in Olympia Heights, where a mismeasured radius or a missing NOA document can set a project back weeks.
We’re not a national chain with a guy at a kiosk selling whatever window fits in the truck. We’re the one down the road, and we stock parts for the brands local homeowners actually have.
Our Custom & Geometric Windows Services in Olympia Heights
Custom Impact Windows
Every replacement window in Olympia Heights, including custom impact windows, must carry a Miami-Dade Notice of Acceptance. This is a non-negotiable product approval protocol that goes beyond the standard Florida Building Code. We spec, order, and install NOA-listed impact units sized to your actual rough opening. On a 1962 CBS ranch near Coral Way, that meant building window packages around masonry openings that hadn’t been square since the day the block was laid. We handle the permit, the product approval documentation, and the final inspection paperwork, so your insurer sees exactly what was installed.
Geometric & Shaped Windows
Hexagons, octagons, trapezoids, circles, and something close to a parallelogram that a homeowner sketched on a napkin. We’ve done all of them in Olympia Heights. This is not a stock item. It’s a fabricated unit built to a drawing, ordered in an HVHZ-compliant configuration, and installed only after the opening is prepped and the permit is approved. Our team reviews the wall’s structural capacity before we cut or widen anything. On 1960s CBS construction, that review is not optional. Spalling and cracked CMU blocks happen when someone cuts first and engineers later.
Arched & Curved Windows
Olympia Heights has a surprising number of arched openings hiding behind aluminum-framed squares. Homeowners with 1960s and 1970s ranches often discover a curved concrete header behind the old window once it’s out. We spec arched impact units to that exact radius, and we’ve learned to order from fabricators who actually document the NOA on curved glazing. A curved transom that arrives with a Florida Product Approval but no NOA at final inspection is worse than useless. It voids the wind-mitigation discount and gives your insurer grounds for non-renewal. We confirm NOA documentation before the unit ever leaves the factory.
Oversized Openings
A floor-to-ceiling impact window spanning a family room wall in Olympia Heights is a different job from a single replacement unit. The opening count changes, the design pressure across the glass changes, and the framing or masonry reinforcement changes. We’ve installed oversized custom units on homes near Tropical Park where the wall was 14 feet of concrete block with a single undersized window. The new opening required an engineering stamp, a header, and a permit that tied back to the Miami-Dade HVHZ product approvals. We pulled the permit, managed the inspection, and kept the neighbors informed every step of the way.

Trusted Brands We Service in Olympia Heights
We’re an authorized installer for PGT, CGI, and several other premium lines, and our Olympia Heights customers often ask about Mr-Glass, ECO Window Systems, and Therma-Tru by name. That’s fine. We stock glass and hardware locally so turnaround on service calls is faster, and we’ll work on any brand we install, no warranty gymnastics. If you’ve got an older custom unit that’s fogged or a curved sash that’s binding, we’ll tell you honestly whether it’s worth repairing or replacing, and we’ll quote the brand-correct part either way.
Common Custom & Geometric Windows Problems We See in Olympia Heights Homes
- Non-HVHZ-listed custom shapes rejected at permit review. A homeowner orders a beautiful octagon online, then finds out Miami-Dade won’t let it into the wall. That’s a two-week delay, a full redesign, and money already spent on a unit that can’t be legally installed here.
- Original jalousie frames failing around custom replacements. Many Olympia Heights homes still have 1960s jalousie tracks built into the block. When you pull one to install a custom impact unit, the surrounding concrete is often cracked or spalled. We inspect before we order anything.
- Missing NOA documentation at final inspection. The window is in, the glass is impact-rated, the permit was pulled, but nobody documented the NOA for the insurer. Final inspection fails, the wind-mitigation discount never lands, and the homeowner is left holding paperwork we should have handled.
- Zero-lot-line dust control failures. On shared walls along Southwest 97th Avenue’s tighter lots, cutting and grinding without a dust guard sends masonry powder onto a neighbor’s screened porch. We use negative-pressure saw guards and staged containment so the abutter sees no mess.
Pricing for Custom & Geometric Windows in Olympia Heights, FL
What Custom & Geometric Windows Costs in Olympia Heights
Impact windows generally run $800 to $1,500 per window installed. A custom impact single-hung in Olympia Heights lands closer to $900 to $1,800 because the sizing and NOA documentation add cost over a stock unit. Large or custom openings, such as a full-height picture window or a big arch, run $2,500 to $5,000. Whole-home packages start around $8,000 and climb past $25,000 depending on opening count, wind zone requirements, floor height, and frame material. In Olympia Heights, the HVHZ wind zone and the age of the home’s block construction push most jobs toward the middle of those ranges. We give you a fixed written quote after a free in-home measure, so the number we agree on is the number you pay.
Florida Pays You Back
The incentives stack up in ways most homeowners never hear about. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and Olympia Heights’s HVHZ status often moves homes to the front of that list. Florida also exempts impact-resistant windows and doors from sales tax, which is real money on a $15,000 job. The federal 25C energy credit covers 30% of the product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, which typically costs $75 to $150, homeowners commonly see windstorm-premium credits that average around 25% on the windstorm portion of the policy. Programs and carriers set the final numbers. We’ll point you to the right documentation; we won’t promise a specific credit.
The Olympia Heights Permit Reality Nobody Warns You About
Here’s what makes this page different from any generic custom windows write-up. In Olympia Heights, every replacement window, including custom geometric and arched units, must carry a Miami-Dade Notice of Acceptance. That’s a county-level product approval protocol with teeth. It goes beyond what the Florida Building Code requires elsewhere, and it prohibits off-the-shelf non-listed units even if those units meet wind-mitigation benchmarks in Broward or Palm Beach. A homeowner who buys a custom octagon window from a supplier in Fort Lauderdale and assumes it’ll pass here is in for a rough conversation at permit review. The unit gets rejected, the project stalls, and the homeowner eats the cost of a window that can’t legally enter an Olympia Heights wall.
Our team’s job starts before the measurement. We check the NOA listing, confirm design pressures match the specific opening, and pull the permit with the paperwork in order. Every PGT or CGI unit we order for this neighborhood has the Miami-Dade NOA tied to the exact configuration going into that exact wall. We don’t guess, and we don’t let the homeowner guess.
Working Tight Lots on the West Side of Olympia Heights
On a zero-lot-line CBS ranch near Southwest 97th Avenue, our crew replaced a set of original 1964 jalousie windows with PGT custom arched impact units. Each unit required a Miami-Dade NOA and custom sized sashes because the rough openings were 1.5 inches narrower than modern standard. The neighbors on both shared walls got 48-hour notice and signed party-wall agreements before we put up scaffolding. Our installers kept staging within the two parking spaces the permit tethered us to in front of the home, and we ran a negative-pressure saw guard to keep masonry dust off the abutter’s screened porch.
That’s the job, every time, in this part of Olympia Heights. Tight lots, shared walls, work-hour ordinances, and permit complexity that a less local crew would bungle. We keep the site clean, the noise within legal hours, and the neighbors informed. It all goes into the quote, by the way. Access affects the price, so we’d rather show up, look at the lot lines, and give you a number that reflects reality.

FAQs - Custom & Geometric Windows in Olympia Heights
Do geometric and arched windows need a Miami-Dade NOA in Olympia Heights?
Yes. Every replacement window in Olympia Heights, including geometric and arched units, must carry a Miami-Dade Notice of Acceptance. The HVHZ mandate is non-negotiable, and a unit without the NOA will fail permit review and can void your hurricane-windstorm insurance discount. Call (727) 620-6983 and we’ll verify your unit’s listing before any work starts.
Can I install a custom-shaped impact window in my 1950s CBS wall without altering the structure?
Usually yes, if the new unit fits the existing rough opening. But many Olympia Heights CBS walls have jalousie frames or odd rough openings that don’t match modern sizing. In those cases we may need masonry buck modifications or an engineer’s review before we finalize the design. We do not cut a larger opening without checking the block’s structural capacity first. That’s what prevents spalling and cracked CMU.
How do you keep dust and debris off my neighbor’s house when you replace a window on a shared wall?
Direct answer: we stage within the space the permit allows and run negative-pressure saw guards with dust containment whenever we’re cutting or grinding near a shared wall. We also give neighbors 48-hour notice and sign party-wall agreements before scaffolding. On the tightest lots in Olympia Heights, that protocol is the only way to work without creating a dispute.
Will my homeowners insurance give a better rate if I replace jalousie windows with custom impact units?
Yes, in most cases. Olympia Heights insurers are actively non-renewing or surcharging policies on homes that lack fully permitted impact openings. Replacing your jalousie windows with NOA-listed custom impact units, then documenting the NOA at final inspection, is what triggers the wind-mitigation credit. The typical windstorm-premium reduction after a wind-mitigation inspection averages around 25% on the windstorm portion of the policy. Get the free quote at (727) 620-6983.
Do the afternoon thunderstorms in Olympia Heights affect how you spec custom window seals?
Yes. Olympia Heights sits just east of the Everglades and takes extreme humidity plus intense afternoon thunderstorms from spring through fall. That accelerates frame corrosion and seal failure on older units. We spec sealants, gaskets, and frame finishes rated for Miami-Dade’s humidity and rain-load conditions, and we won’t install a seal package cut for a drier climate. It’s a small detail that saves a big repair later.
