Oversized Openings in Fort Lauderdale, FL

Oversized window openings – those exceeding the standard rough-opening dimensions most production builders frame for – require a different level of planning, structural assessment, and installation craft than a standard replacement job. In Fort Lauderdale, where older ranch homes in neighborhoods like Coral Ridge and Imperial Point were built with modestly sized aluminum jalousie frames, and where newer waterfront construction pushes toward floor-to-ceiling glass walls, oversized openings sit at both ends of the market. TruePane Windows & Doors handles both: the careful enlargement of an existing opening to accept a statement picture window, and the precise fabrication and installation of our Custom & Geometric Windows services for a unit large enough to frame an Intracoastal view the way it deserves to be framed.

If you’re planning a project like this, the first question is almost always structural. Enlarging or custom-filling an oversized opening in Fort Lauderdale typically runs between $1,800 and $6,500 or more, depending on structural work required, the glass specification, and the unit size. Most jobs we complete in a single crew visit once the custom unit is on-site. For a free, no-pressure estimate, call us at (754) 310-3589 – a live person answers around the clock.

This service falls under our broader work with Custom & Geometric Windows in Fort Lauderdale, which covers the full range of non-standard window configurations we fabricate and install across South Florida. If you want the background on how we approach custom work generally, that page is a good starting point. For oversized openings specifically, here’s what the process looks like and what to expect.

When You Need Oversized Openings

Not every window project is a straight swap. These are the situations that typically lead a Fort Lauderdale homeowner to call us about an oversized opening:

• You’re replacing a wall of jalousie or louvered aluminum with a single large unit. Dozens of homes in Lauderdale Harbours and Coral Ridge still have original 1960s aluminum jalousie frames across an entire wall face. Converting that expanse to a fixed picture window or large casement system means working with an opening that no production window catalog addresses.
• You’re removing a wall or enlarging a rough opening to improve a view or increase light. Fort Lauderdale’s prevailing southeast breeze and proximity to water mean that even a modest enlargement – say, widening an opening from 48 inches to 72 inches – can transform how a living room feels. This work requires a structural header assessment and, in most cases, a permit from the City of Fort Lauderdale Building Services Division.
• You ordered a custom unit that existing framing won’t accept. This happens more than it should. A homeowner selects a large Marvin or CGI impact unit, and the rough opening falls two inches short in width or height. We handle the frame adjustment and the install as a single coordinated scope.
• A new addition or remodel left a raw opening that needs a custom-sized unit. Contractors building additions in neighborhoods like Sailboat Bend or Tarpon River often leave window openings framed to dimensions that aren’t stock. We measure, specify, and install the unit that fills it correctly.
• You want a fixed glass wall or near-floor-to-ceiling unit in a waterfront home. For homes along the New River or along Fort Lauderdale’s finger canals, large fixed-glass panels have become the standard ask. These units routinely exceed 60 inches in width and 84 inches in height – well outside anything a big-box store carries.
• The existing oversized unit failed – fogged glass, failed seals, or frame corrosion – and the replacement has to match the custom dimensions exactly. Fort Lauderdale’s salt air is hard on aluminum frames. When a large unit fails, the replacement has to be fabricated to the same opening, not retrofitted from a production size that’s close but not right.

Our Oversized Openings Process

The founding rule Dale Kessler keeps on the whiteboard – if the pane is not true, the job is not done – applies nowhere more literally than on an oversized opening. A large unit that’s off by an eighth of an inch at the sill reads as a noticeable gap, a binding frame, or a seal that fails in its first South Florida summer. Here’s how we work through a project like this:

1. Site assessment and structural review. Before we quote anything, one of our technicians visits the home and looks at the existing opening – the framing, the header, the sill condition, and the wall cavity. For any opening enlargement, we flag whether a structural engineer’s sign-off will be needed before the permit application goes in. Fort Lauderdale’s Building Services Division requires permitted drawings for most structural window openings, and we walk homeowners through what that paperwork looks like rather than leaving them to figure it out alone.
2. Precision field measurement – twice. Our technicians measure every dimension of the opening twice before a fabrication order is placed. On an oversized unit, a quarter-inch error in the field translates directly to a unit that either won’t fit or will require shimming that compromises the thermal and impact seal. We record the diagonal measurement as well – because a rough opening that looks square often isn’t.
3. Side-by-side manufacturer quotes on paper. Once we have exact dimensions and a confirmed specification (glass type, impact rating, frame material, operability), we pull quotes from the manufacturer lines that can produce that unit – commonly CGI or ES Windows for impact-rated work, or other authorized lines depending on the application. We put those quotes side by side on paper so you see exactly what each option costs, what the lead time is, and what the warranty covers. No vague verbal estimates.
4. Permit coordination and structural header work. If the opening is being enlarged or if the unit exceeds specific size thresholds, we coordinate the permit submission with Fort Lauderdale Building Services. Where a new or reinforced header is required, we work with a licensed structural contractor to complete that scope before the window unit arrives on-site. We don’t skip this step – an unpermitted structural opening is a liability that follows the home through every future sale or insurance claim.
5. Installation and leveling. When the custom unit arrives, installation is scheduled as a single crew visit. Oversized units require more hands and purpose-built lifting equipment – we don’t muscle a 150-pound glass panel into position and hope for the best. The unit is set level, plumb, and square. Flashing and sealant are applied to manufacturer spec, which matters for both the warranty and South Florida’s wind-driven rain events.
6. Warranty registration before the truck leaves. The Keystone Standard applies to every job we complete. Before the crew leaves the driveway, both manufacturer warranty layers are registered in writing – product warranty and installation warranty – with the durations stated. You get a copy. If anything reads or operates incorrectly within 90 days, the 90-Day Done Right Promise covers it: we come back, we fix it, no paperwork fight, no arguing about whether it was the product or the install.

Oversized Openings Pricing in Fort Lauderdale

Oversized window openings in Fort Lauderdale typically cost between $1,800 and $6,500 or more for the full scope – unit fabrication, installation labor, flashing, and permit coordination. Projects that involve structural header work or significant framing modifications run at the higher end of that range and sometimes beyond it. Here’s a cleaner breakdown of the variables that move the number:

A few things worth knowing about Fort Lauderdale specifically: impact-rated glass is not optional if you want to maintain homeowner’s insurance compliance in Broward County. Most insurers now require Miami-Dade or Florida Building Code product approval (NOA) on any new or replacement window unit. For oversized openings, this narrows the qualifying manufacturer list – not every brand that makes large units makes Custom Impact Windows with a valid Florida NOA. CGI and ES Windows are two of the lines we routinely spec for oversized impact work in this market.

Salt air corrosion is another Fort Lauderdale-specific cost driver. On homes within a half mile of the Intracoastal or the ocean, we sometimes find that existing framing has corroded to the point where it needs replacement before a new unit can be properly anchored. We’d rather tell you that during the site visit than after the unit is on-site.

Seniors and veterans receive a permanent 5% discount on all TruePane work. If a repair component of the job exceeds $250, the standing $50 Off Any Repair Over $250 offer applies. Estimates are free and upfront – no line items appear on the final bill that weren’t on the estimate.

FAQs – Oversized Openings

Do I need a permit to install an oversized window in Fort Lauderdale?

Yes, in most cases. The City of Fort Lauderdale Building Services Division requires a permit for any window installation that involves structural modification to the opening – widening, heightening, or adding a new header. Even a like-for-like replacement of a large custom unit may require a permit if the unit’s size triggers Florida Building Code thresholds. TruePane handles permit coordination as part of every project that requires it; we don’t leave homeowners to navigate that process alone. Unpermitted structural window work creates real problems when it comes time to sell or file an insurance claim – it’s not a step worth skipping. Call (754) 310-3589 and we can walk you through what your specific project requires before you commit to anything.

How long does it take to get a custom oversized window fabricated and installed?

Lead time for Geometric & Shaped Windows or other custom-fabricated oversized units typically runs three to six weeks from the time the order is placed, depending on the manufacturer and the complexity of the specification. Impact-rated units in non-standard sizes for the Fort Lauderdale market generally fall in the four-to-five-week range. Installation itself is usually completed in a single crew visit once the unit is on-site – most oversized jobs we complete in four to eight hours depending on whether structural header work is part of the scope. We schedule the installation date when the unit ships, so you’re not waiting by the phone for a moving target. Call (754) 310-3589 for a timeline specific to your project.

What’s the largest window size TruePane can install in Fort Lauderdale?

There’s no practical upper limit on single-panel width or height that we won’t at least assess – the constraint is what a given manufacturer can fabricate within Florida Building Code impact ratings and what the structural opening can accept. For fixed-glass panels, we regularly install units exceeding 72 inches wide and 96 inches tall in Fort Lauderdale waterfront homes. Arched & Curved Windows and operable units (casement, awning) have tighter maximum size limits set by each manufacturer because of the hardware load. When you call, we’ll ask for the rough opening dimensions, the wall construction type, and whether you need an operable unit or fixed glass – that information narrows down which manufacturer lines apply and what’s achievable. Call (754) 310-3589 and we’ll give you a straight answer.

Does TruePane handle both the structural work and the window installation, or do I need separate contractors?

TruePane coordinates the full scope. For projects that require structural header work – which is common when an existing opening is being enlarged – we work with a licensed structural contractor and fold that coordination into the project timeline so you’re dealing with one point of contact, not two or three. We’ve been doing this in Fort Lauderdale long enough to know which structural contractors work cleanly and on schedule. What you won’t get from us is a situation where the window installer and the framing contractor are blaming each other and you’re left in the middle. The 90-Day Done Right Promise covers the complete installed result – if it’s not right, we sort it out. Call (754) 310-3589 to talk through what your project involves.
