Fast, Reliable Custom & Geometric Windows Across Olympia Heights
Custom and geometric windows in Olympia Heights are a different animal than standard replacements. You’re not just swapping glass. You’re engineering a shaped opening to survive 175+ mph design pressures in the strictest wind-load jurisdiction in the country. Winslow Windows & Doors has been doing exactly that since 2011, and Ed Winslow’s name is on the door – and on every job we do. If you’re looking at an arched picture window, a trapezoid transom, or a wall of oversized impact glass that brightens a 1960s CBS living room, call (850) 721-1218. We’ll tell you straight what it takes, what it costs, and how long it’ll run.
Why Winslow Windows & Doors Is Olympia Heights’s Preferred Custom & Geometric Windows Company
Homeowners here don’t need a national chain with a ticket number. They need a local crew that knows the difference between a Miami-Dade Notice of Acceptance and a Florida Product Approval, because that one distinction determines whether your inspection passes or your insurance renews. We pull permits on every custom and geometric window job in Olympia Heights. We submit the NOA paperwork with the product approval drawings. We don’t ask you to figure out wind-mitigation credits on your own.
Ed Winslow founded this company in 2011 and still answers the phone. A live person picks up around the clock, not a voicemail loop. Our technicians are background-checked and arrive in uniform, so you know who’s at your door before you open it. And our Done Right Promise backs every installation: if it’s not done right, we make it right. Every quote is line-item and written, with upfront pricing and no change orders unless you approve them in writing first.
We’re also authorized installers for PGT, CGI, CWS, and ES Windows, among others. That matters when a custom arch needs to be fabricated to a specific radius and glazed with laminated impact glass that carries an NOA. We’re not guessing at the supply house. We’re ordering from manufacturers we’ve worked with for over 15 years, and we know their lead times, their engineering tolerances, and their paperwork. If you’ve been burned by a contractor who assumed Broward County rules apply in Olympia Heights, you already know how expensive that mistake gets.
Our Custom & Geometric Windows Services in Olympia Heights
Most of what we do here starts with a specific opening in a specific house. Olympia Heights is full of 1950s, 60s, and 70s concrete block and stucco homes where the original jalousie windows are failing 4-Point inspections and the homeowner needs more than a standard retrofit. Below are the services we handle most often in this part of Miami-Dade County. For a deeper look at what we offer across the region, see our Custom & Geometric Windows service hub.
Custom Impact Windows
Custom impact windows in Olympia Heights are not an upsell. They’re the baseline. Every replacement window must carry a Miami-Dade NOA, and that includes the shaped glass. We work with PGT and ES Windows to fabricate units that match your existing opening dimensions – or the new opening dimensions we frame for your remodel – and we submit the NOA with every permit application. A typical custom impact window in Olympia Heights runs $1,200 to $2,800 installed, depending on size, shape, and frame material.

Geometric & Shaped Windows
Trapezoids, triangles, pentagons, and parallelograms all show up in Olympia Heights homes, often as angular transoms or side-lites flanking a front door. These openings were rarely built to modern engineering standards. We measure every side and angle precisely, order the unit to exact specifications, and if the existing masonry opening is out of square – which is common in 60-year-old CBS construction – we reframe and refit before the glass goes in. The right fix is reframing, not caulk.

Arched & Curved Windows
Arched windows are the most likely to fail inspection if a crew cuts corners on radius specifications or weatherstripping. The curved jamb has to be sealed correctly against driven rain, or you’ll see salt-laden air corrode hardware within a few years. We install arched impact windows with proper jamb extensions and marine-grade finishes, and we make sure the radius matches the NOA drawings exactly. In Olympia Heights, we’ve replaced arched units over entryways on homes near SW 40th Street and Bird Road that were installed incorrectly by previous contractors and failed wind-mitigation re-inspection.

Oversized Openings
Large custom openings – picture windows, French openings, walls of glass – carry real structural responsibility in a 1960s CBS home. The original lintels were rarely sized for the weight of a modern laminated impact unit. We check the lintel first, and when it’s undersized, we reinforce it before the window goes in. This is exactly the kind of work that makes a quote higher than a standard retrofit, and we’d rather tell you upfront than hit you with a surprise after the wall is open.

Common Custom & Geometric Windows Problems We See in Olympia Heights Homes
- Shaped windows installed with Florida Product Approval instead of a Miami-Dade NOA. This is the most expensive mistake we see in Olympia Heights. A window passes in Broward County and fails immediately here. The permit is rejected, or the insurance non-renewal stands, and the homeowner pays twice.
- Undersized lintels sagging under the weight of large impact-glass units. Original steel lintels in 1950s-70s CBS homes were not designed for laminated glass that weighs twice as much as the old single-pane jalousies. Cracked stucco above a new window is the signature symptom.
- Radius corners and arched jambs sealed incorrectly. If the sealant fails at a curved jamb, driven rain and salt air get in, hardware corrodes, and the buck framing rots. We’ve opened walls in Olympia Heights where the previous install looked fine from the outside and was rotten from the inside.
- Retrofit crews sizing custom openings wrong. A geometric window can’t be “close enough.” If the rough opening is out of square by half an inch and the installer shims it with whatever’s in the truck, the sash binds, the seal breaks, and the NOA is void. We reframe and machine new jamb extensions to match the engineered opening.
Pricing for Custom & Geometric Windows in Olympia Heights, FL
You won’t get a real number from a website form, but you should get an honest range. For Olympia Heights, a single custom geometric impact window typically runs $1,400 to $2,600 installed, including permit and NOA paperwork. A large arched picture window over an entryway often lands between $2,500 and $4,500. An oversized opening with steel reinforcement can push $5,000. Whole-home packages that replace a mix of shaped and standard windows generally start around $12,000 and go up from there, depending on the number of openings, glass package, and frame material. Every project gets a free in-home measure and a written line-item quote before you sign anything. No allowances hidden in the fine print. Call (850) 721-1218 to schedule it.
What Custom & Geometric Windows Costs in Olympia Heights
Let’s put numbers on it. Impact windows in general in this market run $800 to $1,500 per window installed. A standard impact single-hung falls between $900 and $1,800. Large or custom openings – which is most of what we do in Olympia Heights – run $2,500 to $5,000 per opening, driven by engineering time, fabrication, and the structural work required in older concrete block homes. Whole-home packages typically fall between $12,000 and $25,000 depending on size. What moves price here more than anywhere? The wind zone. Olympia Heights sits inside the HVHZ, meaning 175 to 185 mph design pressures govern every opening. Add floor height, number of openings, and whether we need to reinforce a lintel or reframe an out-of-square masonry opening. You’ll get a written estimate with real numbers. No vague allowances, no “we’ll see once we open the wall.” We inspect first, write the allowance into the contract if it’s needed, and get your approval in writing before any change.
And we compare well against alternatives. Hurricane shutters cost less upfront, but you’re still hanging panels at 2 a.m. while a storm closes in, and shutters do nothing for your energy bills on the other 360 days of the year. A permanently installed impact window with an NOA works every hour of every day, and it’s what insurance underwriters actually reward. If a big-box retail installer quotes you a lower price for a “custom” window, check what approval it carries. In Olympia Heights, if it’s not Miami-Dade NOA, it’s not a legal install.
Florida Pays You Back
There’s a reason Olympia Heights homeowners replace windows on the insurance renewal calendar rather than ahead of storm season. The incentives stack. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Impact-resistant windows and doors are exempt from Florida sales tax. The federal 25C energy credit covers 30% of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection, windstorm premium credits often average around 25% on the windstorm portion of your policy. The inspection itself runs $75 to $150. We can’t promise exact numbers – programs change and every carrier underwrites differently – but we can point you to the right inspector and make sure your paperwork supports every credit available.

FAQs - Custom & Geometric Windows in Olympia Heights
A Miami-Dade NOA is required for every replacement window and door in Olympia Heights, period. Florida Product Approval is not sufficient here. Olympia Heights sits entirely within the High Velocity Hurricane Zone, and a window without an NOA will fail inspection and can hold up your permit indefinitely. Call (850) 721-1218 and we’ll tell you whether your plans meet the standard before you spend another dollar.
We inspect the opening before we order the window. If the masonry opening is undersized or out of square, or if the lintel can’t carry the weight of a laminated impact unit, we write the reframing and reinforcement into the original contract as a visible allowance. You approve the actual cost in writing before we touch the wall. That’s how we keep surprises off your invoice.
Yes, and it happens constantly in Olympia Heights. Jalousie windows are non-impact-rated and a licensing inspector will flag them on a 4-Point inspection. Many homeowners get a non-renewal notice and only then discover they need NOA-certified impact replacements. That’s the single biggest job driver in this neighborhood, and it’s why we keep our quoting process fast and our paperwork airtight.
They will, and more than a standard window. Original jalousie windows leak enormous amounts of unconditioned air. Impact glass with a low-E coating cuts solar heat gain, and when the glass is shaped to fit the actual opening with proper sealing, you stop paying to cool the sidewalk outside. In Olympia Heights summer humidity, the difference is noticeable on your first FPL bill after install.
Custom fabrication runs 4 to 6 weeks once the order is placed. The NOA paperwork is submitted with the permit and doesn’t add much time if the manufacturer already carries the approval for that configuration. Standard-size units can be installed in as fast as a single day once they arrive. Call (850) 721-1218 and we’ll give you a real timeline, not a guess.
