We know which drawings get approved and which ones get sent back.

Key takeaways:

• Every custom geometric window in North Miami requires a Miami-Dade NOA label, including non-rectangular shapes.
• Impact-rated custom units in North Miami typically run $1,100 to $3,800 per opening installed; oversized custom openings run higher.

• You’ll get a written, line-item quote before you sign anything. No change orders down the line.

Why Winslow Windows & Doors Is North Miami’s Preferred Custom & Geometric Windows Company

North Miami homeowners keep calling us back because we do the unglamorous parts right: the permit package, the NOA verification, the masonry anchoring, and the water intrusion details that fail quietly years later when a bad crew skips them. We’ve pulled custom opening permits for homes along NE 125th Street, worked in the canal-front lots around Keystone Point, and retrofitted 1960s CBS block homes near North Miami High School where the original fenestration was never square to begin with.

Every technician who arrives at your North Miami home is background-checked and in uniform. You’ll know who’s walking up your driveway before the truck stops. And when you call, a live person answers, 24 hours a day. No voicemail loop, no call center routing to an out-of-state queue.

Ed Winslow owns this company. He publishes his address and license number. The Done Right Promise is exactly what it sounds like: if we don’t do the job right, we come back and make it right, for as long as you own the home. That’s a lasting standard, and it’s the reason North Miami customers don’t worry about warranties that evaporate after the check clears.

Our Custom & Geometric Windows Services in North Miami

Custom Impact Windows

In North Miami, an impact window is not a marketing word. It’s a Miami-Dade County requirement: every window and door product must carry a NOA from the county’s own testing program. That goes double for custom shapes. We order impact-rated units sized to your rough openings, with laminated glass interlayers tested to withstand large-missile impacts, and we document the NOA number for your permit file and your insurance paperwork.

Geometric & Shaped Windows

Pentagons, trapezoids, circles, and half-rounds look dramatic, but in North Miami they must still meet the same large-missile impact standard as a plain rectangle. That means the glass interlayer, the frame profile, and the anchoring schedule all have to be engineered for the shape, not just the square footage. We’ve ordered and installed shaped units for mid-century CBS homes near the North Miami Public Library and for new canal-front builds that wanted glass corners.

Arched & Curved Windows

An arched window with a generic Florida Product Approval label instead of a Miami-Dade NOA will get your permit rejected in North Miami. We see that exact stall every few months when a homeowner starts with an out-of-area quote. The frame on an arched unit has to be fabricated to the curve, the laminated glass has to hold its shape under design pressure, and the sill flashing has to shed water on a radius, not a straight line. We order from manufacturers that submit their curved units for Miami-Dade testing, so the NOA is real and the permit goes through.

Oversized Openings

North Miami’s 1950s through 1970s CBS homes were built with small punched openings and heavy masonry walls. When you want a 12-foot or 16-foot custom glass wall in a home like that, the structural work is the real job. We size headers, spec masonry anchors, and engineer the design pressure rating to the actual wall assembly, not a generic table. On a canal-front street in Keystone Point, we removed a 1968 aluminum sliding glass door whose weep holes had corroded shut from brackish air, swelling the frame into the CBS opening. Our crew spent two days cutting and shoring the block surround before setting a custom 12-foot PGT impact-rated door with an NOA-approved panel and anchoring pattern that a flat-rate quote from an out-of-area crew would never have accounted for.

Trusted Brands We Service in North Miami

We’re authorized installers for PGT, CGI, ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, among others. That authorization matters in North Miami because the manufacturer’s own installation spec is part of what the NOA certifies. When we order a custom unit from ES Windows or a curved panel from Mr-Glass, the fabricator knows we’ll install it to the tested anchoring pattern, and the warranty stays intact. We also keep common trim packs, anchors, and sealants in local inventory for North Miami jobs, so punch-list fixes don’t wait on a shipping queue.

Common Custom & Geometric Windows Problems We See in North Miami Homes

• Corroded aluminum frames on canal-front lots. Brackish air off the Oleta River and the canal network east of Biscayne Boulevard chews through non-marine-grade aluminum in a few years. By the time we see the frame, the weep holes are often sealed shut with white oxide and the sashes bind against the track.
• Original jalousie windows in 1950s and 1960s CBS homes. Jalousies leak air and water by design and they don’t meet impact standards. Replacing them with custom impact units usually means removing the old aluminum channel, resizing the opening, and flashing the new frame into the block.
• Wrong spec on custom shapes. A custom arch ordered with a Florida Product Approval label instead of a Miami-Dade NOA will be turned down at the permit desk in North Miami. The job stalls, the homeowner pays storage on the unit, and the contractor who quoted cheap is suddenly unreachable.
• Wind-driven rain through poorly anchored oversized windows. In a 1960s CBS home, a large custom window installed with a standard nailing fin and no masonry anchors never actually reaches its design pressure rating. The first real storm finds the gaps and the jamb leaks.

Pricing for Custom & Geometric Windows in North Miami, FL

A standard impact-rated custom window in North Miami runs about $1,100 to $2,000 installed, unit only, before any structural work. Geometric shapes like pentagons and trapezoids add 15 to 30 percent for fabrication and more if the glass interlayer must be special-ordered to pass large-missile testing. Arched and curved units run $1,800 to $3,800 per opening, and oversized custom window walls in existing CBS homes usually land between $4,000 and $9,000 installed once you factor in header work, masonry anchoring, and shoring.

The price moves on four things in North Miami: how many openings, what wind zone your street sits in, how high off the ground the unit sits, and whether your walls are CBS block, frame, or a mix. We measure every opening, write the quote line by line, and hand you a fixed price. If you’d like a second opinion, we’ll review any written estimate you already have, free.

What Custom & Geometric Windows Costs in North Miami

If you’re budgeting for this project, here are the working numbers we use with North Miami homeowners:

Older North Miami homes with original openings rarely have standard-sized rough openings, so custom sizing is the norm, not the upgrade. That’s why “average window price” comparison charts never hold up here. The free in-home measure and written quote we provide will give you the real number for your specific walls, and you’ll get it in writing before any deposit.

Florida Pays You Back

North Miami homeowners can stack several incentives on impact window upgrades. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation improvements, and impact-resistant windows and doors are exempt from Florida sales tax. On the federal side, the 25C energy credit covers 30 percent of the product cost on qualifying units, up to $600 per year. After a wind-mitigation inspection, which runs about $75 to $150 in this area, many North Miami homeowners see windstorm-premium credits averaging around 25 percent on the wind portion of the policy. Every program has its own qualifications and every carrier sets its own final numbers; we’ll point you to the application paths, but the fund amounts and credits are between you, the state, and your insurer.

One comparison worth making: impact windows versus hurricane shutters. Shutters only protect when someone is home to hang them, and on a custom geometric window the shutter panel has to be fabricated just as precisely as the window itself. Permanent impact glass does the job every day of the year, with no panels to store, and it’s what Miami-Dade’s wind mitigation credits were built around.
