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

Fast, Reliable Custom & Geometric Windows Across North Miami

Custom and geometric windows in North Miami are not a side business for us. They are one of the reasons Ed Winslow put his name on this company. When you live in a 1960s CBS home off NE 125th Street, or run a canal-front property near Keystone Point, your openings were never standard. Jalousie louvers, odd trapezoids, arched transoms. We measure, fabricate, and install windows that fit the opening you actually have, not the one a catalog assumes. And every unit we set in North Miami carries a Miami-Dade NOA. That part is non-negotiable. Call (239) 310-4121 and we will walk the job with you.

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

We are the Custom & Geometric Windows team homeowners call after a big-box installer tells them their opening is “too unusual.” North Miami is full of unusual openings. The city’s post-WWII concrete block stock, built between roughly 1950 and 1975, went up fast and with whatever jalousie or single-pane aluminum unit the builder could buy by the pallet. That means few of those openings are square, few are standard size, and almost none meet today’s HVHZ wind-load requirements. We know that before we arrive. Ed Winslow founded this company in 2011, and our crews have spent years working the residential streets between Biscayne Boulevard and the Keystone Point border. You get a background-checked technician in uniform, a written line-item quote, and an owner who answers the phone at 2 a.m. when a storm is coming and a window is out.

Our North Miami customers consistently tell us two things. First, that we called before we pulled up. Second, that the number on the quote matched the number on the final invoice. That second one should not be remarkable, but homeowners who have been burned by vague allowances and surprise change orders know it is. No trip charge inside the home county. A free second opinion on any written estimate you have from another contractor. And our Done Right Promise behind every install.

Our Custom & Geometric Windows Services in North Miami

Custom Impact Windows

Every custom impact window we install in North Miami is engineered to the specific design pressure of the opening, then fabricated with a Miami-Dade NOA. That is not optional here. North Miami sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone, the strictest product-approval standard in the country. A window that carries a Florida statewide approval but lacks a Miami-Dade NOA will fail inspection and trigger removal. We will not sell you a unit that cannot pass. We size for the rough opening as it actually exists, order the frame in a corrosion-resistant finish suited to North Miami’s salt air, and set it with stainless fasteners.

Geometric & Shaped Windows

Trapezoids, pentagons, rake windows, circle-tops. North Miami’s 1950s and 1960s homes were built with plenty of them, many now failing at the seal or seized at the hardware from decades of Biscayne Bay humidity. We template each opening in person, not from a builder’s plan. A geometric window cut even a half-degree off will bind at the corners or leak at the sill. Our crews have cut and set enough of them in North Miami to know exactly how the opening will measure before the old unit comes out.

Arched & Curved Windows

An arched window on a North Miami canal home is often the focal point of the whole front elevation. It is also the most likely window to have been replaced incorrectly at some point in the last 40 years. We regularly pull arched units to find the masonry opening was never properly radiused, or a previous installer forced a rectangular frame into a radiused opening with shims and caulk. We reframe to the true arc, then set an impact-rated arch-top from PGT or Mr-Glass with a laminated glass interlayer that meets HVHZ missile-impact thresholds.

Oversized Openings

Floor-to-ceiling and wall-to-wall glass is a growing request in North Miami, especially in the waterfront-canal streets near the Keystone Point border where owners want the water view. An oversized opening changes the structural load on the lintel above it. On many North Miami CBS homes, the existing lintel was sized for a small jalousie, not a 12-foot span of impact glazing. We check the load path before we order the unit. If a structural upgrade is required, we put it in the quote before you sign, not as a change order after the wall is open.

Trusted Brands We Service in North Miami

We are an authorized installer, which means the manufacturer actually trains our crews and honors the warranty through us. In North Miami, we stock and install PGT, CGI, Therma-Tru, and Mr-Glass, among others. For custom and geometric work, PGT and Mr-Glass give us the most flexibility on radiuses, angles, and laminated glass configurations. We do not sell “brand X or something like it.” You pick the brand, we order the exact unit, and we handle the warranty registration before we leave the job. If a seal fails or a laminate delaminates down the road, you call us. We are the warranty contact in North Miami, not a call center.

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

• Seized jalousie hardware from salt air. North Miami’s inland proximity to Biscayne Bay means unprotected aluminum frames corrode fast. We regularly see original jalousie operators so seized that the sashes cannot be removed without cutting the jamb, which turns a simple window swap into a rough-opening rebuild.
• Non-HVHZ windows installed by a previous owner. This is the most expensive surprise in North Miami. A homeowner had windows replaced in 2015 with units that carry a Florida statewide approval but no Miami-Dade NOA. A permit pulled today for any remodel triggers mandatory removal and replacement of those units before a Certificate of Occupancy can be issued.
• Out-of-square rough openings on 1960s CBS construction. Concrete block homes from that era were framed fast. We routinely find rough openings that are one to two inches out of square in both directions. A custom window cut to the planned dimensions will not sit right. We measure, then reframe with pressure-treated lumber and stainless fasteners before the new unit goes in.
• Undersized lintels over new oversized openings. When a North Miami homeowner wants to enlarge a window or turn a wall into glass, the existing lintel often cannot carry the new span under HVHZ design pressures. We check the load path before ordering anything. If the lintel needs replacing, that goes in the written quote.

Pricing for Custom & Geometric Windows in North Miami, FL

What Custom & Geometric Windows Costs in North Miami

Here are real anchors for North Miami’s market. Impact windows, installed, run roughly $800 to $1,500 per window. If you choose single-hung impact units, figure $900 to $1,800 per opening. Large or custom geometric openings run $2,500 to $5,000, and whole-home packages on older North Miami homes run $8,000 to $25,000 and up depending on the count. Three things drive the price in North Miami more than anywhere else we work. First, the HVHZ engineering package. Every custom unit has to be engineered to the specific design pressure of the opening, and the laminated glass required for missile impact is not cheap. Second, the rough-opening condition. A 1964 CBS home with original jalousies almost always needs reframing before a modern impact unit will sit and seal. Third, permit triggers. If we find prior non-HVHZ work, those units have to come out before the city issues a Certificate of Occupancy. We write allowances into the contract for exactly these discoveries, so you are not surprised. Free in-home measure and written quote before you spend a dollar.

Florida Pays You Back

North Miami homeowners have access to real money for this work. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, which includes impact windows. Florida also exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit can return 30% of the product cost on qualifying units, up to $600 per year. And after a wind-mitigation inspection, which runs around $75 to $150, many insurance carriers in South Florida apply a windstorm-premium credit averaging around 25% on the windstorm portion of your policy. We cannot guarantee what your carrier will approve or what the state will fund. We can tell you what qualifies, help with the paperwork, and install units that meet the program standards. That part we control.

FAQs - Custom & Geometric Windows in North Miami

What Opening Up an Older North Miami Home Actually Turns Up

North Miami’s housing stock is mostly concrete block and stucco, built from roughly 1950 to 1975. When we open a wall on one of these homes, we find what decades of humidity, salt air, and previous owners left behind. Outdated wiring stapled to the backside of a window jamb. Undersized or water-damaged framing around an original jalousie. Failed waterproofing at the sill that has been weeping into the block for 20 years. And frequently, a window installed by a previous owner that carries no Miami-Dade NOA, which means it has to come out before the inspector will pass the job. This is the single biggest reason a North Miami window quote moves between the estimate and the final invoice.

We handle it a specific way because Ed Winslow never wanted a homeowner surprised on his watch. Inspection first. We open, we show you, and we photograph it. Then allowances written into the contract from the start, sized for what we actually expect to find on a North Miami home of your era. And any surprise priced and approved in writing before we touch it. That is not a slogan. It is how we run a job. If we find a non-HVHZ window from a prior remodel, you get a change order with an exact price and you sign it before we order the replacement. No “we will figure it out later.” Later is where homeowners get burned.

One thing worth saying plainly. A window with Florida statewide approval but no Miami-Dade NOA is not legal in North Miami once a permit is pulled. We see this constantly. A homeowner in 2015 bought windows from an out-of-county supplier, got them installed without a permit, and now needs a remodel. The permit triggers mandatory removal. It is not a technicality and it is not negotiable with the inspector. We have handled enough of these in North Miami that we build the contingency into the contract up front. That is what local expertise actually means. It means we have already seen your house 40 times before we ring the bell.

Salt air is the other constant. North Miami sits just inland from Biscayne Bay, and unprotected aluminum frames pit and seize within 10 to 15 years. Geometric window hardware is especially vulnerable because the sashes are heavier and the operators have more contact points to corrode. We use corrosion-resistant finishes and stainless fasteners on every North Miami installation, not as an upgrade. It is the only way the window will still operate 15 years from now.

If you are considering shutters instead, understand the tradeoff. Hurricane shutters protect the glass during a storm, but you have to store them, carry them, and hang them in the dark with a storm bearing down. Impact windows protect the home permanently. No panels. No ladder. No remembering which track goes where. For a North Miami homeowner who travels or who simply does not want to wrestle corrugated steel at 11 p.m., impact glass is the practical choice. The My Safe Florida Home grant and windstorm-premium credits make the upfront number far more reasonable than it looks on a raw quote.
