Fast, Reliable Custom & Geometric Windows Across The Hammocks
Custom and geometric windows in The Hammocks run anywhere from $1,200 for a modest single fixed geometric unit to $5,000 or more for a fabricated arched or radius impact window with Miami-Dade NOA approval. Two approvals govern every job here: the Hammocks Community Association’s architectural review first, then a Miami-Dade building permit tied to a NOA product approval number. Skip either one and the inspection fails. Winslow Windows & Doors has been navigating both since 2011, and our crews work The Hammocks neighborhoods off SW 104th Street, SW 117th Avenue, and the villa communities near Hammocks Boulevard every week.

Why Winslow Windows & Doors Is The Hammocks’s Preferred Custom & Geometric Windows Company
Ed Winslow’s name is on the door, and it’s on every custom window order we take in The Hammocks. That’s a different kind of accountability than a national chain offers. We answer our own phone, 24 hours a day. When a homeowner in the 33196 zip code calls about a fogged arched window or a geometric opening that needs impact glass, they talk to someone who knows this community, not a call center reading a script.
Our reputation in The Hammocks is built on jobs that pass inspection the first time. We’ve replaced custom radius windows in the villa sections north of Hammocks Boulevard, done oversized picture window retrofits in the single-family homes east of SW 147th Avenue, and pulled more architectural review applications through the Hammocks Community Association than most contractors in the area combined. The HOA layer trips up out-of-area installers constantly. It doesn’t trip us up, because we start with it.
Every technician who arrives at a The Hammocks home is background-checked and in uniform. You’ll know who’s at your door before the truck pulls up. And our Done Right Promise means if a custom window isn’t done right, we make it right. No expiration date. No fine print. That’s the standard Ed built the company on and it hasn’t moved in over 15 years.
Our Custom & Geometric Windows Services in The Hammocks
Custom Impact Windows
A custom impact window in The Hammocks has to do two jobs at once: hold its shape against hurricane wind loads and satisfy the HOA’s design rules. We order from PGT, CGI, CWS, ES Windows, and ECO Window Systems, all with Miami-Dade NOA numbers matched to the specific opening size and design pressure. For homes in The Hammocks’s HVHZ wind zone, that usually means a laminated glass interlayer and a reinforced frame engineered for the exact dimensions of the window, not a stock unit cut down to fit.

Geometric & Shaped Windows
Triangles, trapezoids, octagons, pentagons. The Hammocks homes built between 1985 and 1995 used a lot of these shapes, especially in gable ends and entryways. Many still have their original single-pane aluminum frames with no impact rating at all. We fabricate replacement geometric units to the same sight lines and grille patterns the Hammocks Community Association approves, then add the structural reinforcement that current Miami-Dade code requires. You keep the look. You gain the protection.

Arched & Curved Windows
Arched and radius windows were a signature feature in late-1980s and early-1990s Hammocks construction. They’re also the hardest windows to bring up to impact code, because the curved frame has to carry the same wind load as a square frame while maintaining a true radius. Our crew recently replaced a failing arched window in a 1991 villa off SW 104th Street where the original non-impact aluminum frame had corroded at the jamb and the single-pane sash had fogged beyond repair. We installed a PGT custom radius impact window with a Miami-Dade NOA and laminated glass interlayer, matched the HOA’s required bronze frame color and colonial grille pattern, and pulled the permit through the Hammocks Community Association review first. The project passed inspection in one visit and the homeowner’s wind mitigation report now lists full opening protection.

Oversized Openings
Oversized picture windows and wide sliding-door transoms need design pressure calculations that standard windows don’t. In The Hammocks, those openings often sit on second floors or in two-story great rooms, which pushes the wind-load requirements higher. We spec the frame, glass thickness, and anchoring to the exact opening dimensions, then file the Miami-Dade permit with the matching NOA numbers. Nothing is left to guesswork.

Trusted Brands We Service in The Hammocks
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, and three other premium manufacturers. For custom and geometric work in The Hammocks, we lean most often on PGT and CGI for impact-rated curved and shaped units, and CWS or ES Windows when a homeowner wants aluminum frames with a specific HOA-approved color. Because we order directly from these manufacturers, not through a distributor, we get accurate lead times and correct NOA documentation on every custom order. Custom fabrication typically runs four to six weeks once the order is placed.
Common Custom & Geometric Windows Problems We See in The Hammocks Homes
- Fogged insulated glass in geometric shapes. The humidity in southwestern Miami-Dade runs above 75% year-round. Insulated glass units in triangles, arches, and octagons fail faster than rectangular ones because the sealant bond is stressed along non-standard edges. Once the seal breaks, the unit fogs and the energy performance is gone.
- Oxidized aluminum frames on pre-Andrew homes. Flat limestone terrain with no coastal buffer means full sun exposure. Homes built before August 1992 still carry original aluminum frames in geometric openings, and three decades of UV and salt air have left jamb corners pitted and corroded. The frame won’t hold a new impact unit without replacement.
- HOA non-compliance at inspection. We’ve seen out-of-area contractors install a perfectly good NOA-approved window in The Hammocks, then fail the Miami-Dade inspection because the frame color or grille pattern didn’t match what the Hammocks Community Association’s architectural review requires. The window gets red-tagged, removed, and reinstalled. It adds two to four weeks and thousands in labor.
- Single-pane glass in geometric openings with no impact protection. Miami-Dade insurers are increasingly non-renewing properties without verified opening protection. A triangle or octagon with original single-pane glass is a non-compliant opening, and it’s often the one that kills a wind mitigation report. Homeowners in The Hammocks call us because the insurance letter arrived.
Pricing for Custom & Geometric Windows in The Hammocks, FL
Custom and geometric window pricing in The Hammocks is driven by three things: the complexity of the shape, the wind-load rating required for the opening, and the frame material. A standard fixed octagon in impact-rated aluminum starts around $1,200 installed. A radius or arched impact window runs $1,800 to $3,400. A fully custom curved unit with a Miami-Dade NOA and laminated glass typically lands between $2,500 and $5,000, and whole-home packages with multiple custom openings range from $8,000 to $25,000 or more depending on opening count. Our quotes are written, line-item, and fixed. If we quote you a number, that’s the number on the invoice. Call (844) 901-4551 to schedule a free in-home measure.
What Custom & Geometric Windows Costs in The Hammocks
Here’s a clearer breakdown for The Hammocks’s market, so you can budget realistically before you call. Impact windows generally run $800 to $1,500 per window installed. Impact single-hung units sit between $900 and $1,800. Large or custom openings, meaning anything arched, radiused, or unusually wide, fall between $2,500 and $5,000. Whole-home packages with a mix of standard and custom shapes start around $8,000 and climb past $25,000 on larger two-story homes. The variables that move your number: how many openings, what floor they sit on (second-floor openings carry higher design pressures), whether the HOA requires a specific frame color or grille pattern that limits manufacturer choices, and whether the existing jamb can be reinforced or needs full replacement. Our in-home measure is free and the written quote we leave with you is the price you pay. No change orders later. Call (844) 901-4551.
Florida Pays You Back
The incentive stack in Florida is real, and it applies to impact-rated custom windows in The Hammocks. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and custom impact windows typically qualify when the opening is verified as protected. Florida waives sales tax on impact-resistant windows and doors, which saves you 6% or more in Miami-Dade on the product cost. The federal 25C energy credit returns 30% of product cost on qualifying units, capped at $600 per year. And after a wind mitigation inspection (usually $75 to $150), most homeowners see windstorm premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers, so we encourage you to confirm with your agent, but the credits are there for The Hammocks homeowners who document compliance properly.
One comparison worth thinking through: impact windows versus hurricane shutters. Shutters protect the opening but you have to put them up and take them down every storm, and a geometric window needs a custom shutter track that often looks worse than the window it’s protecting. Impact windows protect permanently, no panels to hang, no storage, no scramble when a watch is posted. For The Hammocks homeowners who travel or who don’t want to wrestle with shutters at 2 a.m., impact glass is the cleaner solution, and it carries the same wind mitigation credit on your insurance.
On ratings: every custom window we install in The Hammocks carries a Miami-Dade NOA or Florida Product Approval number matched to the specific configuration, HVHZ compliance where the opening’s wind zone requires it, and design pressures matched to the opening. We never spec a window with a rating above the opening’s actual requirement, and we never install without the NOA documentation in hand for inspection.

FAQs — Custom & Geometric Windows in The Hammocks
Yes, every custom geometric window in The Hammocks needs two approvals before installation can be finalized: an architectural review through the Hammocks Community Association (covering frame color, grille pattern, and glass tint) and a Miami-Dade building permit tied to a NOA product approval number. We handle both, and we file the HOA review first because Miami-Dade won’t finalize the permit without the association’s sign-off. Call (844) 901-4551 and we’ll map the sequence for your specific opening.
A custom arched window in The Hammocks must carry a Miami-Dade NOA with large-missile impact testing, not just small-missile, because the HVHZ wind zone applies across the community. The NOA number must match the exact size and shape of your opening, which is why a stock impact unit can’t simply be recut to fit a radius or arch. We spec the design pressure and NOA documentation for every custom unit before ordering. Call (844) 901-4551 for a free measure and we’ll show you the NOA papers for your exact opening.
In most cases, no. Pre-Andrew aluminum frames in geometric openings weren’t engineered for impact-rated glass, and the jamb and sash don’t carry the design pressure ratings HVHZ requires for those shapes. Replacing only the glass leaves you with a window that won’t pass Miami-Dade inspection and won’t satisfy a wind mitigation report. We recommend full frame replacement when we see original pre-Andrew frames, and we’ll show you the structural math on that recommendation during your free estimate. Call (844) 901-4551.
A custom geometric window permit in The Hammocks typically adds two to four weeks over a standard rectangle because of the Hammocks Community Association architectural review layer, which doesn’t apply to non-HOA communities but applies to every home in The Hammocks. The HOA review runs one to three weeks depending on submission volume, then Miami-Dade permit review adds another week or more. We file the HOA paperwork on day one so the clock starts immediately. Call (844) 901-4551 and we’ll give you a realistic timeline for your specific project.
Yes, when every opening including the geometric ones is verified impact-rated with NOA documentation and a wind mitigation inspection confirms full opening protection, most Miami-Dade insurers apply a windstorm premium credit that averages around 25% on the windstorm portion of the policy. The key is that the custom openings have to be properly documented, because an HOA-approved window without the correct NOA can still be disallowed. We give you the full documentation package for your insurer after installation. Call (844) 901-4551 to get started.
