Custom & Geometric Windows in North Miami - Free In-Home Measure, Written Price

We Replace Salt-Air-Damaged Windows in North Miami Before They Fail

In North Miami, custom and geometric windows are not just a design choice. They’re a structural decision shaped by two things: Miami-Dade’s High Velocity Hurricane Zone code and the salt air that rolls off Biscayne Bay. We regularly replace arched, radius, and oversized impact windows in Keystone Point that looked fine from the living room but had frame corners corroded to white powder after 12 years. A cheap inland-spec frame dies fast here. A marine-grade build survives. That’s the conversation we have with every North Miami homeowner, and it starts with a free in-home measure and written quote. Call (850) 998-3090 to schedule yours.

Key Takeaways:

• Every replacement window in North Miami must carry a Miami-Dade NOA (Notice of Acceptance). No Broward-spec shortcuts.
• Custom arched and geometric impact windows in North Miami typically run $2,500-$5,000 per opening, installed and flashed to HVHZ standards.
• Salt air near the bay corrodes standard aluminum frames, weep holes, and jamb hardware within 12-15 years. We specify 316 stainless hardware and marine-grade finishes on every coastal job.
• Original 1950s-1970s jalousie openings are 30-40% too small for today’s NOA-certified custom geometric windows, so framing work drives the project before materials ever arrive.
• Winslow Windows & Doors is owner-operated by Ed Winslow, in business since 2011, with a live person answering the phone 24/7.

Fast, Reliable Custom & Geometric Windows Across North Miami

If you live in a concrete block ranch home near NE 6th Avenue or a waterfront property off NE 135th Street, you’ve probably been told your current windows are a problem. Jalousie louvered windows on a 1960s CBS home are not just inefficient. Florida insurers are actively canceling and non-renewing policies over them. North Miami falls entirely inside the HVHZ, so every replacement we install carries a Miami-Dade NOA number and is matched to the specific wind load of your opening, your floor height, and your exposure to the bay. We know this because we do it here every week. Ed Winslow’s name is on the business, and his crews are in North Miami regularly, not making a two-hour drive from some regional call center. When you call (850) 998-3090, a real person picks up, day or night.

North Miami’s housing stock is not like Coral Gables or Aventura. The core of the city is single-story CBS homes built between 1950 and 1975, and those rough openings were framed for thin aluminum single-panes or jalousies. That means a custom arched or geometric window job here almost always involves re-framing, re-headering, and flashing work before the new unit goes in. We handle that in-house. One crew, one accountable owner, one written quote with no surprises.

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

We’re locally owned and owner-operated. Ed Winslow founded the company in 2011, and he answers for the work. That’s not a slogan. It’s a phone call you can make right now. North Miami homeowners call us because a background-checked, uniformed technician shows up when we say he will, with a written line-item estimate and a straight answer about whether your existing frame can be saved. Most of the time it can’t, and we’ll tell you that before you spend money.

Our reputation in North Miami comes from jobs like the Keystone Point casement we pulled last year. Twelve-year-old PGT impact unit, glass still intact, but the powder coat was blistering and the weep-hole tracks inside the sash channels had turned to white dust. The homeowners wanted a matching arched fixed window over a new radius transom. We rebuilt that geometric assembly with 316 stainless hot-dip corner keys and site-flashed a buck so the replacement won’t repeat the same salt-air death in another decade. That’s the difference between a window seller and a Custom & Geometric Windows specialist who understands North Miami’s air.

We do not subcontract the site measure or the install. The person who signs your estimate is the same owner who stands behind the Done Right Promise: if it’s not done right, we make it right. Period.

Our Custom & Geometric Windows Services in North Miami

We handle four types of work most often in North Miami. Each one starts with a free in-home measure, a structural review of the existing opening, and a written quote that includes all framing, flashing, and haul-away. No change orders, no surprise line items.

Custom Impact Windows

In North Miami, an impact window is not a product. It’s a tested assembly: glass, frame, hardware, and anchoring, all matched to a Miami-Dade NOA. We install PGT and CGI impact units sized and fabricated for your exact rough opening, then anchor them to Miami-Dade wind-load requirements. If you have a 1970s single-pane slider facing Biscayne Bay, that window is an insurance liability, not just an energy loss.

Geometric & Shaped Windows

Triangles, pentagons, trapezoids, and custom radius corners. North Miami’s mid-century homes sometimes have original shaped louvered openings that owners love. The problem: those openings were not framed for today’s NOA-certified glazing. We open them up properly, sister headers in where the 1960s carpenter skipped them, and install a geometric unit that actually passes a Miami-Dade wind mitigation inspection. If you’ve got an insurer threatening cancellation over a jalousie opening, this is the fix.

Arched & Curved Windows

Arched windows are common on the 1980s garden-style multifamily buildings throughout North Miami, and on a lot of custom single-family ranches along NE 16th Avenue. The failure we see most: aluminum arch units with standard stainless-seal weep covers corroding at the mitered corners, then racking under pressure and blowing the insulated glass seal. We spec marine-grade finishes and hot-dip galvanized corner keys on every arch unit. It costs more up front. It costs less than replacing the window again in eight years.

Oversized Openings

Floor-to-ceiling assemblies, picture windows with radius transoms, corner-opening sliders. In North Miami’s CBS construction, an oversized opening means cutting concrete block and adding structural support. We pull permits, we pull load calcs, and we install to NOA. If a big-box installer tells you they can drop an oversized window into an existing jalousie opening without touching the header, get a second opinion. Then call us at (850) 998-3090 for the free one.

Trusted Brands We Service in North Miami

We’re an authorized installer for PGT, CGI, and Therma-Tru, and we regularly specify ViewLux for custom radius and geometric shapes. The brand matters for the glazing. What matters more in North Miami is the frame alloy, the hardware, and the flashing. A PGT unit with standard aluminum corners will still die early in Keystone Point. A PGT unit with 316 stainless corner keys and marine weep flaps will outlast it by a factor of three. We order the right configuration, and we stock common parts locally so a service call in North Miami doesn’t turn into a six-week wait for a hardware kit.

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

• Salt-air frame rot on impact units. In Keystone Point and other bay-adjacent neighborhoods, we see 12-15-year-old impact windows with glass intact but frame corners and weep-hole tracks corroded to white powder. The glazing was fine. The frame was not coastal-spec.
• Undersized headers from jalousie-era rough openings. Homeowners on a budget reuse the original rough opening for a larger geometric window. The header was never sized for HVHZ wind loads. The result fails Miami-Dade wind mitigation inspection and invites cancellation.
• Corner sweating on large custom geometrics. North Miami’s year-round humidity finds sharp mitered joints without a continuous thermal break. Condensation stains the interior drywall and mold follows. We spec continuous thermal breaks on every custom geometric assembly.
• Blown seals on aging low-E arch and casement units. UV intensity and humidity harden the glazing gaskets within five to seven years. Air leaks in, the SHGC drifts, and you get condensation between the panes. A fogged arch window in North Miami is not repairable; it’s a re-order.

Pricing for Custom & Geometric Windows in North Miami, FL

What Custom & Geometric Windows Costs in North Miami

The four things that move the price in North Miami: opening count, wind zone, floor height, and frame material. A single-story home on a quiet street off NE 125th Street is at the lower end of the wind-load table. A two-story waterfront property in Keystone Point is at the top. The same arched window costs more in Keystone Point because the design pressure requirement is higher, the anchoring is heavier, and the frame finish must be marine-grade. A cheap inland-spec geometric window might save you $600 on the day of install. It will be corroding at the corners in ten years, and you’ll pay for the same job twice. We’d rather quote the right number the first time and stand behind it. Call (850) 998-3090 for a free in-home measure and written quote.

Florida Pays You Back

The incentives stack, if you know where to look. My Safe Florida Home matching grants can cover up to $10,000 of qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit applies to qualifying units at 30% of product cost, up to $600 per year. And after a wind-mitigation inspection (typically $75-$150), most Florida insurers credit the windstorm portion of your premium by around 25%. That last number is an average across carriers, not a promise. But the math is real: the marine-grade custom window we install today usually pays for itself through insurance savings and energy credits long before the cheap window would have failed. One comparison worth making: impact windows against hurricane shutters. Shutters are panels you store, maintain, and physically hang before a storm. Impact windows are permanent protection, always in place, and they count toward the same wind-mitigation credits. In North Miami, where every hour of prep matters before a storm, permanent protection wins.

We also do not do Broward-spec work in Miami-Dade County. It fails early here, and it’s not legal for new construction or replacement. If a quote from another contractor does not include a Miami-Dade NOA number for your specific configuration, that quote is not for a window you can legally install in North Miami.

We Also Serve Cities Near North Miami

Our crews cover North Miami and the surrounding cities, including Hialeah, Miami, Miami Beach, and Pembroke Pines. If you’re just over the county line in Broward, the NOA requirement changes, but the salt air does not. We spec every coastal job the same way: marine-grade finishes and hardware that will still be intact in 15 years. Call (850) 998-3090 and we’ll tell you which spec applies to your address.
