Fast, Reliable Custom & Geometric Windows Across North Miami
Custom and geometric window replacement in North Miami runs $1,200 to $4,800 per opening installed, depending on size, shape, and Miami-Dade NOA product approval requirements. Many homeowners pair this with a Roof Replacement & Installation - North Miami to fully protect the envelope. Most custom-shaped units take 4 to 6 weeks to fabricate, then install in as fast as a single day once the units arrive. Ed Winslow has been running this company since 2011, and his crews know North Miami’s mid-century concrete-block ranches block by block. If you’re standing in a 1960s house on NE 135th Street staring at oxidized aluminum jalousie windows, call (727) 860-0593 and a live person will answer, 24/7.
Why Winslow Windows & Doors Is North Miami’s Preferred Custom & Geometric Windows Company
North Miami’s housing stock is old enough that generic window shops get lost here. Most homes between NE 119th and NE 151st Street were built between 1952 and 1978, and the openings were never sized for modern impact units. That means full-frame, rough-opening replacements, every time. Our crews have done hundreds of tear-outs on CBS ranch homes near Arch Creek and Keystone Point, so we can tell you before the truck rolls up whether your rough opening needs re-framing, strap upgrades, or structural filler before a new geometric unit goes in. We also handle Shingle, Tile & Metal Roofing - North Miami if your project includes roof work.
We’re authorized installers for PGT, CGI, CWS, ES Windows, ECO Window Systems, and three other premium brands, and we carry parts locally for North Miami customers. Every technician is background-checked and shows up in uniform, with a name and a face you can verify before anyone touches your wall. Ed Winslow’s name is on the business, his address and license number are published, and the Done Right Promise backs every job. If it’s not done right, Winslow makes it right. Period.
Our Custom & Geometric Windows Services in North Miami
Custom Impact Windows
Every replacement window in North Miami must carry a Miami-Dade Notice of Acceptance (NOA) number. This isn’t optional. Miami-Dade’s NOA system is stricter than the Florida Building Code and stricter than Broward County across the county line. A custom impact window from Winslow is fabricated to your exact rough opening, glazed to the design pressure your wall requires, and documented with the NOA stamp that your permit inspector will ask for. We handle the paperwork, the permit, and the inspection.

Geometric & Shaped Windows
Half-rounds, pentagons, trapezoids, fixed triangles above sliders. North Miami’s mid-century homes love these shapes, and most of them are currently leaking or drafty single-pane aluminum. We build NOA-certified geometric impact units that match the original sightlines but meet current wind-borne debris standards. The frame is engineered to the opening, not shimmed into a stock rectangle with caulk.

Arched & Curved Windows
Arched windows near Biscayne Bay take a beating from salt-laden onshore air. Non-marine aluminum frames oxidize, corner welds crack, and the unit loses its design pressure rating silently. We specify stainless steel hardware and marine-grade finishes on arched units within a few miles of the bay, like the homes along NE 121st Street and around Enchanted Forest Park. The curved frame is templated on-site, then cut and welded to the exact radius.

Oversized Openings
Floor-to-ceiling custom openings, picture windows, and fixed walls of glass. On North Miami’s older CBS ranch homes, these openings often need new headers or reinforced rough sills. We don’t hide that work in a change order. Upfront line-item pricing, no surprises on the invoice, and a full written quote before we start.

Trusted Brands We Service in North Miami
We install and service custom and geometric windows from PGT, CGI, ES Windows, and ECO Window Systems. Each brand has specific NOA configurations for Miami-Dade’s wind zone, and we stock common parts and hardware locally so North Miami customers aren’t waiting on out-of-state shipments for service calls. If you have a failing geometric window and need a brand-matched replacement, we can usually pull the spec from the original NOA label and get the right unit ordered the same visit. Our Custom & Geometric Windows team handles the full lifecycle, from initial measure to final inspection.
Common Custom & Geometric Windows Problems We See in North Miami Homes
- Salt-air oxidation on aluminum frames. Homes east of NE 6th Avenue, closer to Biscayne Bay, see non-marine aluminum frames corrode within 10 to 15 years. Corner welds crack first, then the frame loses design pressure. It’s the single most common issue we find in the neighborhoods between NE 123rd and NE 135th Street.
- Jalousie windows with no legal upgrade path. Those original louvered jalousie windows still working in North Miami’s 1950s and 1960s homes cannot be made hurricane-compliant with any film, patch, or retrofit. Miami-Dade’s building department requires full removal and a NOA-certified impact unit. Many homeowners find this out only when an insurance inspection refuses to renew coverage.
- Driven rain saturating concrete block around arched and oversized openings. Poorly sealed rough openings let South Florida’s sideways rain get into the block. Hidden corrosion eats the jamb anchors over time, and the window eventually fails a large-missile impact test even if the glass looks fine.
- Non-compliant replacements from out-of-county contractors. Some installers from Broward or further north will swap in a Florida Product Approval unit that lacks a Miami-Dade NOA. North Miami permit inspectors will reject it. That homeowner is out the money, the window, and the job.
Pricing for Custom & Geometric Windows in North Miami, FL
A typical custom impact window in North Miami runs $1,200 to $3,400 per opening installed. Geometric and shaped units, like half-rounds and pentagons, run $1,800 to $4,800 because the frame is cut and welded to your exact radius. Oversized fixed windows and window walls start around $2,500 and can reach $5,000 or more depending on wind zone, floor height, and glass package. Whole-home packages on a 1950s North Miami ranch usually land between $8,000 and $25,000 depending on opening count and frame material. The biggest local price drivers are rough-opening condition, proximity to Biscayne Bay (marine-grade hardware costs more), and whether the original opening needs re-framing. If you’re curious about the range for entire homes across Florida, our guide explains what Custom & Geometric Windows in North Miami homeowners typically pay and why the coastal spec matters.

What Custom & Geometric Windows Costs in North Miami
Impact windows in North Miami generally run $800 to $1,500 per window installed, with single-hung impact units at $900 to $1,800. Large or custom-shaped openings run $2,500 to $5,000, and whole-home packages on a typical 1,200-square-foot CBS ranch range from $8,000 to $25,000 or more. Three things move the price in North Miami specifically: opening count and condition, wind zone (homes east of Biscayne Boulevard are in a higher exposure category), and frame material. Marine-grade aluminum with stainless hardware costs 15 to 25 percent more than inland-spec, but replacing it a decade later costs the full job again. We offer a free in-home measure and a written quote with no obligation.
You should also know the comparison hook before you put real money down. Impact windows beat hurricane shutters in North Miami because they’re permanent protection. No panels to drag out of a shed, no mounting hardware corroding in salt air, no waking up at 2 a.m. with a storm offshore and nothing on the glass. A licensed impact specialist who pulls the permit and passes the inspection is a different animal from a big-box retail install with a third-party sub who won’t know what an NOA is until the inspector asks. That distinction costs homeowners real money in North Miami every year.
Florida Pays You Back
The incentives stack if you do the paperwork. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact windows. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit returns 30 percent of product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75 to $150), most North Miami homeowners see their windstorm premium drop around 25 percent on the wind portion of the policy. We don’t control those programs, and the final numbers come from your carrier, but we’ll tell you what documentation you need after install. Call (727) 860-0593 and Ed or a team member will walk you through it.

FAQs - Custom & Geometric Windows in North Miami
Jalousie windows cannot be upgraded because their louvered design has no sealed structural frame capable of passing Miami-Dade’s wind-borne debris test. The building department requires full removal and a NOA-certified impact replacement. No patch, film, or retrofit product gets around this. If an insurance inspection flagged your jalousies, you need full replacement. Call (727) 860-0593 and we’ll measure every opening on the same visit.
Salt air oxidizes non-marine aluminum within 10 to 15 years in North Miami’s eastern neighborhoods, cracking corner welds and destroying the frame’s design pressure rating. Choose marine-grade aluminum with stainless steel hardware, or specify a vinyl-clad composite if the design allows. The coastal-spec version costs more upfront, but the inland-spec version fails a decade in and you pay the full job twice. Call (727) 860-0593 for a free measure and material recommendation based on your exact block.
Yes, custom arched and shaped impact windows in North Miami typically run $1,800 to $4,800 per opening because the frame is templated and welded to your exact radius, and each configuration needs its own Miami-Dade NOA test documentation. A stock rectangle from the same brand might run $800 to $1,500 installed. The shape drives the price more than the NOA itself. Call (727) 860-0593 for a written quote on your specific openings.
Miami-Dade NOA is a county-level product approval that exceeds the Florida Building Code. A window with only Florida Product Approval will not pass a North Miami permit inspection. Every unit we install has a Miami-Dade NOA number stamped on the frame, listed on the permit, and matched to the design pressure for the opening. No NOA, no permit, no exception.
Yes, in most cases. Fixed geometric frames, casements, and horizontal sliders can replicate the sightlines of a mid-century ranch without the louvered jalousie hardware. We template the original rough opening, match the glazing pattern as closely as the NOA system allows, and use marine-grade finishes in homes near the bay. The look stays. The glass gets stronger. Call (727) 860-0593 and we’ll show you options in your own neighborhood.
North Miami is one of the few Miami-Dade cities where entire streets of original 1950s through 1970s jalousie windows remain in daily use. Because Miami-Dade NOA approval is stricter than neighboring Broward County, no patch, film, or retrofit can make those louvered windows legal. Only a full tear-out and NOA-certified impact replacement qualifies. That reality drives a first-time, full-system replacement market here that is uniquely large in this older, working-class municipality. On a 1963 concrete-block ranch near NE 135th Street, our crew pulled a set of original aluminum jalousie windows that had been eating salt air off Biscayne Bay for sixty years. The aluminum frames were so oxidized they crumbled at the corners, and the jalousie clips had fused into the jambs. We replaced the entire rough opening with Miami-Dade NOA-certified PGT custom impact windows; fixed geometric frames plus a matching casement for egress, with stainless steel hardware and marine-grade finishes, because the old spec would have failed again within a decade.
