AfterOversized Openings in Palm Beach, FL
Oversized window openings in Palm Beach typically involve custom-fabricated frames that exceed standard residential sizing – think single-lite units running 60 inches wide or taller, floor-to-ceiling picture windows facing the Intracoastal, or wide-span openings designed to bring the Atlantic light deep into a room. For our Custom & Geometric Windows services, If your home calls for something a big-box store won’t stock off the shelf, that’s exactly the work we do at Winslow Windows & Doors.
We’ve been handling oversized and architecturally specific installations across Palm Beach since 2011, and Ed Winslow personally oversees every project. This isn’t work you hand off to a crew and hope for the best – oversized openings require precise field measurements, structural coordination, and impact-rated glazing that meets Palm Beach County’s strict hurricane codes. We get that right the first time, and our Done Right Promise means we come back if anything falls short. Call us at (561) 782-7525 – a live person answers around the clock, no voicemail.
Oversized openings fall under our broader Custom & Geometric Windows in Palm Beach service, which covers everything from angled transoms to radius tops. If you’re planning a large opening – or just trying to figure out whether your existing one can be expanded – start with a free estimate.
When You Need Oversized Openings
- You’re replacing a dated picture window that’s fogged, cracked, or leaking air. Older Palm Beach homes – especially those built in the 1960s and 70s along South Ocean Boulevard and the North End – often have large single-pane aluminum windows that were never impact-rated. Replacing them with a properly sized, code-compliant unit fixes both the safety gap and the energy drain.
- You’re doing a renovation and want to expand an existing rough opening. Many homeowners in El Cid and Flamingo Park tear out a wall or raise a header to bring in more natural light. We coordinate with your contractor or structural engineer to ensure the new opening is framed correctly before any glass goes in.
- You need a true floor-to-ceiling window for a water-facing or courtyard view. Palm Beach properties on the Intracoastal or with manicured garden views often specify windows that run from 84 to 120 inches tall. Standard product lines won’t cover that – custom fabrication will.
- Your existing oversized window failed inspection or doesn’t carry a current Miami-Dade NOA. Palm Beach County requires impact-rated products with valid Notice of Acceptance for any window installation. Older large-format windows frequently fail this test during re-roofing permits or full home renovations.
- You’re building new construction or an addition and the architect specified a non-standard size. Architects working on Palm Beach’s historic Mediterranean Revival and modern coastal builds regularly call for windows that don’t fit catalog specs. We custom-order through manufacturers like PGT and ViewLux to match exact drawings.
- Storm damage left a large opening exposed or temporarily boarded. A Category 1 hit can shatter an oversized pane and leave a significant structural gap. We work quickly to assess, measure, and get a fabricated replacement moving through production – and someone answers if you call at 2 a.m.
Our Oversized Openings Process
- Free on-site estimate and structural assessment. We come to your Palm Beach address, measure the rough opening precisely (width, height, diagonal, and depth of the buck), note any header or sill conditions, and discuss what you want the finished unit to look like. There’s no trip charge inside Palm Beach County, and the estimate costs you nothing.
- Product selection and custom fabrication order. Based on your opening dimensions, design goals, and local code requirements, we spec the right impact-rated product. For very large openings, we typically source from PGT or CGI – both manufacture units that carry Miami-Dade High Velocity Hurricane Zone approval and can be built to non-standard sizes. We confirm the NOA number and energy rating before we order.
- Permit pulling and HOA coordination. Palm Beach has one of the more attentive building departments in South Florida, and HOA architectural review committees in neighborhoods like Phipps Ocean Park and the Estate Section review exterior changes carefully. We prepare the permit application, submit product approvals, and handle the back-and-forth so you don’t have to.
- Structural prep and old unit removal. On installation day, our background-checked, uniformed crew removes the existing window or frames the new rough opening to spec. If the header needs to be reinforced for a widened span, we complete that work before any new product goes in. We protect your interior finishes and haul away the old unit.
- Installation and weatherproofing. The new unit is set level and plumb, shimmed, anchored to the buck per the manufacturer’s installation instructions and county code, and then flashed and sealed against Palm Beach’s driving rain. Large openings have more linear feet of perimeter to seal – we don’t rush this step because a poor seal on a big window causes big water damage.
- Inspection, sign-off, and your Done Right review. We schedule and pass the county inspection. Before we leave the job, Ed or a senior crew member walks the installation with you, explains what was done and why, and confirms everything operates correctly. The Done Right Promise activates at that moment – if something isn’t right, call us and we make it right.
Oversized Openings Pricing in Palm Beach
Oversized window installations in Palm Beach run higher than standard replacements for straightforward reasons: the glass itself costs more, fabrication lead times are longer, structural prep is often involved, and permit fees reflect the larger scope. The ranges below are honest market estimates for Palm Beach as of 2025-2026 – not lowball figures designed to get us in the door.
| Opening Type | Typical Installed Cost Range | Notes |
|---|---|---|
| Large picture window (60-84″ wide, single lite) | $1,800 – $3,400 | Impact-rated, standard finish, no structural work |
| Floor-to-ceiling window (84-120″ tall) | $2,800 – $5,500 | Custom fabrication, may require header reinforcement |
| Wide-span fixed or casement (90″+ wide) | $3,200 – $6,800 | Multi-lite or custom unit; structural assessment included |
| Expanded rough opening (wall modification + window) | $4,500 – $9,000+ | Includes framing, header, and permit; varies by wall type |
| Permit and inspection fees | $150 – $450 (Palm Beach municipality) | Billed at cost, no markup |
What moves the number: The biggest cost drivers are glass area (larger lites mean more laminated impact glass), finish and frame color (non-standard finishes add 10-15% on custom orders), whether structural work is needed, and how accessible the opening is. A second-story ocean-facing window on a Palm Beach estate takes more rigging time than a ground-floor unit in a single-story ranch.

Why Palm Beach Homeowners Choose Winslow for Oversized Openings
Palm Beach isn’t a typical Florida market. The properties here – from the historic Mediterranean Revival homes near Worth Avenue to the newer construction along the North End – demand precision and discretion. Permit coordinators know every installer in town. HOA architectural boards look closely at what’s going in. And the salt air off the Atlantic degrades inferior products faster than most homeowners expect.
We’ve worked in this environment since 2011. Ed Winslow’s name is on the business, on the license, on the permit applications, and on every job we complete. That’s not a marketing line – it means there’s a real person accountable to you, not a regional manager three states away. When something needs to be sorted out with the Palm Beach Building Department or an HOA committee, Ed handles it directly.
We’re authorized installers for PGT, CGI, ViewLux, and five other premium brands, which gives us genuine flexibility when matching a custom opening to the right product. A national chain locked into one manufacturer’s catalog can’t always do that. We can. Our home page has a full picture of what we cover across windows, doors, and roofing.
And practically speaking: upfront pricing before any work starts, background-checked technicians in uniform, a live person answering at any hour. Those aren’t extras – they’re the baseline for how we operate.
FAQs – Oversized Openings in Palm Beach
How large can a single impact window be for a Palm Beach home?
Most residential impact window manufacturers, including PGT and CGI, can produce single-lite fixed units up to approximately 96 inches wide and 120 inches tall, though the practical maximum varies by product line and frame profile. For openings larger than that, we typically specify a multi-lite configuration – two or more units joined by a mullion – which actually performs better structurally under hurricane-force wind loads. For Arched & Curved Windows and other specialty shapes, During your estimate, we’ll tell you exactly what’s possible for your opening and which configuration meets current Palm Beach County code. Call (561) 782-7525 to set up that conversation – estimates are free.
Does expanding a window opening require a structural engineer in Palm Beach?
Yes, in most cases. Any time you’re widening or raising a rough opening in a load-bearing wall, Palm Beach’s building department will require engineered drawings showing the new header size and load path. We work with licensed structural engineers regularly and can refer you to one if needed – or coordinate directly if your architect has already engaged one. The permit won’t get approved without it, and we won’t skip that step just to move faster. It protects your home and your insurance coverage.
How long does a custom oversized window take from order to installation?
Custom fabrication lead times in Palm Beach currently run 6 to 12 weeks depending on the manufacturer and the complexity of the order – PGT and CGI both have production schedules that fluctuate with demand, and South Florida’s construction volume keeps that timeline active. Once the product arrives, installation typically takes one to two days for a single large opening, longer if structural prep is part of the scope. We’ll give you a realistic production estimate before you commit, and we track the order so you’re not left guessing.
Will an oversized window replacement affect my homeowner’s insurance rate in Palm Beach?
Replacing a non-impact or non-rated window with a properly installed, Miami-Dade-approved impact unit almost always reduces your homeowner’s insurance premium in Palm Beach. Insurers operating in Florida assess wind mitigation credits based on opening protection, and a certified impact window on a large opening – one that previously may have been the weakest point in your envelope – can shift your credit calculation meaningfully. We provide a copy of the permit, the product’s NOA, and the installation documentation you’ll need to give your insurer. Some carriers also want a wind mitigation inspection report, which is a separate step your insurance agent can walk you through.
