Our Custom & Geometric Windows Services in Gulf Stream
This tier of work isn’t commodity glazing. It’s fabrication, specification, and careful documentation. Here’s what we handle most often in Gulf Stream.
Custom Impact Windows
In Gulf Stream, a custom impact window has to do two jobs at once. It has to meet Palm Beach County’s coastal wind-load requirements, and it has to look like it was original to a 1950s British Colonial estate. We spec units with sculpted colonial or heritage profiles and clear or lightly tinted low-e glass, because Ark-B flat frames and reflective coatings don’t survive ARDB review here. The glass is impact-laminated, the hardware is marine-grade, and the profile is chosen to read correctly from the curb.
Geometric & Shaped Windows
Triangles, trapezoids, pentagons, radius corners. Gulf Stream has plenty of them, and most were custom-cut decades ago. When one fails, you can’t pull a replacement off a shelf. We measure, template, and order from manufacturers who can hold the tolerance. If the original had true divided lights, we match them. If it had simulated muntins, we match those too. The ARDB notices the difference.
Arched & Curved Windows
Large arched windows on Gulf Stream’s estate homes present a specific challenge: aluminum expands and contracts under Florida sun, and an arch that’s not properly reinforced will sag or lose its shape over time. We use reinforced radius frames and impact-laminated glass engineered to hold geometry under design pressures well within the required range for this wind zone. The springline has to be exact, and the radius has to be true. We don’t approximate.
Oversized Openings
Whether it’s a wall of glass facing the Atlantic on a new addition or a replacement opening a builder framed too large for stock units, oversized openings in Gulf Stream demand engineering at the opening level. We match design pressure to the specific opening dimensions and elevation, not a generic rating. These jobs typically fall between $2,500 and $5,000 per opening, depending on size, glass package, and frame profile. We lock that number before ordering.

Trusted Brands We Service in Gulf Stream
We’re an authorized installer for eight premium manufacturers, and for Gulf Stream we lean heavily on ECO Window Systems, Mr-Glass, and CGI. These are brands that understand heritage profiles and marine environments. We don’t just order catalog numbers; for Gulf Stream we submit shop drawings, muntin dimensions, and glass interlayer specs before the first deposit. That documentation is what moves an ARDB review from contested to approved.
What Custom & Geometric Windows Costs in Gulf Stream
Here are real numbers for this market. A standard impact window in Gulf Stream generally runs $800 to $1,500 per window installed. A custom impact single-hung starts around $900 and goes to $1,800 depending on size and profile. Large or custom geometric openings, the kind that dominate Gulf Stream’s estate homes, run $2,500 to $5,000 per opening. Whole-home packages sit between $8,000 and $25,000 or more, driven by opening count, floor height, and the complexity of the profiles.
What moves the price in Gulf Stream? Opening count is the big lever, then wind zone (most of town sits in the highest coastal exposure), then frame material and the degree of custom milling. A second-story installation on a home off Polo Drive costs more than a ground-floor job, and an arched unit with true divided lights costs more than a rectangle with simulated muntins. We’ll give you an exact, written, line-item quote before anything is ordered. Call (561) 816-5648 for a free in-home measure.
| Scope | Typical Range in Gulf Stream |
|---|---|
| Standard impact window, installed | $800 - $1,500 per window |
| Custom impact single-hung | $900 - $1,800 per window |
| Large or custom geometric opening | $2,500 - $5,000 per opening |
| Whole-home package | $8,000 - $25,000+ |
One thing to know: custom fabrication here runs four to six weeks. That’s the lead time from order to delivery, not a delivery promise we can shortcut. We can install most units in as fast as a single day once they arrive. The schedule is set by the factory, not by us, and anyone who tells you otherwise is lying.
Common Custom & Geometric Windows Problems We See in Gulf Stream Homes
- ARDB rejection at first review. A homeowner or a less experienced contractor submits a modern flush-fin frame or tinted glass on a British Colonial elevation. The ARDB rejects it. Now the redesign clock starts, and the project loses weeks. We submit the right profile the first time, with shop drawings and glass specs attached.
- Salt-spray corrosion of hardware and fasteners. Gulf Stream properties front directly on the open Atlantic. Standard aluminum frames and zinc hardware corrode within a few years. We use marine-grade hardware and fasteners on every job here. It’s the difference between a five-year sash and a twenty-year one.
- Waiting to order until after permit approval. The moment the permit is issued, the fabrication clock starts. If you waited, you added four to six weeks to the end of the project. On complex geometric units, the correct sequence is: spec, ARDB review, permit, order. But the order should be staged so materials ship the week the permit clears. We orchestrate that so you’re not staring at a plywood opening.
- Arched window sag under wind load. A large arched window that wasn’t engineered for its opening can lose its shape slowly. The radius flattens, the sash binds, and the glass eventually cracks. We see this on homes where a previous install treated an arched opening like a stock rectangle. The fix is a properly reinforced radius frame, and those are always custom.
The Gulf Stream ARDB Problem, Explained
Here’s what most people don’t know until they’re in it. Gulf Stream’s Architectural Review Board has a documented history of rejecting impact window submittals that use modern flush-fin or flat-profile frames, or tinted and reflective glass. So you can’t simply order any impact unit off a national catalog and expect approval. You need sculpted colonial or heritage profiles, clear or lightly tinted low-e glass, and often true divided lights with muntin dimensions that match the original fenestration. Contractors in Delray Beach or Boynton Beach don’t face this. You do. We know the short list of specialty manufacturers who can produce what the ARDB will approve, and we know how to package the submittal so it doesn’t bounce back.
A recent example from a Gulf Stream estate off Polo Drive: a failing casement assembly needed full replacement. Our crew removed the original units and installed custom impact-rated casements from CGI, matching the original divided-light pattern and heritage profile. The ARDB approval came only after we submitted shop drawings showing the correct muntin dimensions and a clear laminated glass interlayer. We had locked the price in writing before the long-lead order went in. That’s how the job stayed on schedule instead of drifting.
Florida Pays You Back
There’s real money available for this kind of work in Gulf Stream, and you should know how to stack it. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida has a sales-tax exemption on impact-resistant windows and doors, which is meaningful on a five-figure project. The federal 25C energy credit can return 30 percent of the product cost, up to $600 per year, on qualifying units. And after a wind-mitigation inspection ($75 to $150), many Gulf Stream homeowners see windstorm-premium credits around 25 percent on the windstorm portion of their policy. We don’t set these numbers; the programs and your carrier do. But we’ll help you with the documentation so you’re in position to claim what’s available.
And a note on the comparison we hear most: impact windows versus hurricane shutters. Shutters are temporary protection that someone has to deploy. Impact windows are always on. There’s nothing to hang, nothing to store, nothing to forget when a storm is two days out. For a Gulf Stream homeowner who may be away when the warning comes, that’s worth weighing. And we never sell or install shutters. We only do the permanent fix.

FAQs - Custom & Geometric Windows in Gulf Stream
Yes. Gulf Stream’s ARDB rejects tinted and reflective glass on residential elevations. You need clear or lightly tinted low-e laminated impact glass, and the interlayer must be documented in your submittal. The frame profile matters just as much: modern flush-fin and flat profiles don’t pass architectural review here. Call (561) 816-5648 for an exact spec that won’t bounce back.
Both are possible in Gulf Stream, but true divided lights are the default on British Colonial homes where the original fenestration had them. True divided lights mean each pane is a separate piece of impact-laminated glass set into a structural muntin, which costs more than simulated divided lights with a grille applied over a single lite. The ARDB will likely expect true divided lights if your original windows had them. We’ll review your elevation and tell you which route avoids a rejection.
Engineering, not luck. A large arched window needs a reinforced radius frame and glass packages matched to the actual design pressure of that specific opening and its elevation. When we replace an arched unit, we calculate that number and spec the frame to hold its geometry for decades. It costs more than a stock rectangle. It fails less too.
Yes, if the units are impact-rated and carry the required Florida Product Approval numbers. Your insurer looks at the wind-mitigation inspection, not the window’s shape. A geometric or arched impact unit with proper documentation qualifies the same as a standard impact window. Many Gulf Stream homeowners see windstorm-premium credits around 25 percent after the inspection. Call (561) 816-5648 and we’ll help you get the paperwork in order.
Two things, in this order: the ARDB review and the fabrication lead time. ARDB review takes however long it takes, and resubmittals add weeks. Then custom fabrication runs four to six weeks from order. We front-load the submittal so the ARDB clock and the fabrication clock overlap as much as legally possible. Labor on site is rarely the bottleneck. The calendar is set by paper and by the factory.
