Oversized Openings in Boca Raton, FL

Installing an oversized window opening in Boca Raton means cutting or expanding a rough opening in an exterior wall, sourcing a custom-sized impact-rated unit, and making sure the whole assembly meets Miami-Dade and Palm Beach County code requirements. Most oversized window projects in Boca Raton run between $1,800 and $6,500 per opening, depending on wall type, frame material, and the unit itself – and they typically require a permit pulled with the City of Boca Raton Building Division before a single cut is made.

At Winslow Windows & Doors, we’ve been handling these jobs since 2011. Ed Winslow built this company around projects that other installers pass on because the scope feels complicated – and oversized openings are exactly that kind of project. If you’re picturing a dramatic wall of glass facing the Intracoastal, Arched & Curved Windows overlooking your pool, or a grand entryway that makes a statement from the street, call us at (561) 816-5648. Someone answers every call, around the clock, no voicemail.

This page is part of our broader work with Custom & Geometric Windows in Boca Raton – oversized openings are one of the most requested variations we handle in this market.

When You Need Oversized Openings

Not every window project starts with a broken pane. These are the scenarios where homeowners in Boca Raton call us specifically for an oversized opening:

• You’re renovating a coastal or Intracoastal-facing wall and want unobstructed water views. Standard catalog windows top out around 72 inches wide. A true panoramic view of the waterway requires a custom oversized unit – sometimes spanning 10 feet or more – set into an enlarged or purpose-built opening.
• Your architect’s drawings call for a window size that no stock unit covers. In Boca Raton’s newer custom-build neighborhoods like Royal Palm Polo Estates and Broken Sound, architects routinely spec window openings well outside standard dimensions. The builder frames them; we supply and install the unit that fills them correctly.
• You’re replacing an old jalousie bank or a dated sliding window wall with modern impact glass. Older Boca Raton homes in areas like Camino Gardens or Lake Rogers built in the 1960s and 70s frequently have jalousie or awning configurations spanning an entire wall. Converting those to a single oversized impact-rated unit is a structural and aesthetic upgrade in one step.
• Hurricane damage left a structural opening larger than the original window. A storm that compromises the header or framing around an existing window sometimes creates a de facto oversized opening that needs to be properly re-framed and filled with a code-compliant impact unit rather than just patched back to original size.
• You want to combine two adjacent window openings into one continuous expanse. Removing the section of wall between two standard windows to create a single wide opening is one of the most common oversized-opening requests we see in Boca Raton’s mid-century ranch homes. It changes the feel of an interior dramatically and almost always triggers a permit and a structural engineer’s sign-off.
• You’re adding a great room addition or sunroom and need windows sized to the new footprint. Addition framing is built to the architect’s plan, not to standard catalog dimensions. Getting a window that actually fits the new opening – without gaps, shimming, or filler strips – requires a custom oversized unit from the start.

Our Oversized Openings Process

We don’t shortcut this kind of work. Here’s how a typical oversized opening project moves from your first call to final inspection in Boca Raton:

1. On-site evaluation and structural assessment. Ed or a senior member of our crew visits the site to assess wall construction – CBS (concrete block structure) versus wood frame behave very differently when you’re enlarging an opening. We check header sizing, lintel condition, and whether the existing framing can carry the load of a larger span. If a structural engineer’s letter is required by the City of Boca Raton Building Division (and for most opening enlargements, it is), we tell you upfront before you’ve committed to anything.
2. Custom measurement and unit specification. Oversized openings are measured to the fraction of an inch. We specify the unit based on your exact rough opening, your preferred frame finish (white, bronze, anodized aluminum, or painted), glazing type (tempered, laminated impact, or Low-E impact), and the structural wind-load rating required for your specific Boca Raton location. Homes east of Federal Highway face higher design pressure requirements than those further inland – that affects unit selection.
3. Permit filing with the City of Boca Raton. We pull the permit. You don’t call the Building Division, you don’t chase an inspector, and you don’t sign contractor affidavits. That’s our job. Palm Beach County and the City of Boca Raton both require approved plans before any structural opening work begins, and we handle that paperwork as part of the project – not as an add-on fee.
4. Structural opening preparation. For CBS construction, enlarging an opening means cutting concrete block, installing a properly sized lintel, and allowing adequate cure time before the window unit goes in. For wood-frame construction, it means removing and reframing the rough opening with the correct header size for the span. Our crews do this work – we don’t sub it out to a general contractor and disappear.
5. Custom unit delivery and installation. Oversized units from brands like PGT and ECO Window Systems are built to order and typically arrive 4-8 weeks after order placement. Installation is a multi-person job – some of these units weigh several hundred pounds. We use the right equipment, set the unit level and plumb, flash the perimeter to Florida Building Code standards, and apply the appropriate sealant for Boca Raton’s salt-air coastal environment.
6. Final inspection and sign-off. We schedule the City of Boca Raton inspector, meet them on site, and make sure the permit is closed out correctly. You get a copy of the closed permit for your records – something you’ll need when you sell the home. Jobs that skip this step create title problems down the road, and that’s not something we’re willing to do to a client.

Oversized Openings Pricing in Boca Raton

Oversized openings cost more than standard window replacements because there are more moving parts: structural work, custom-fabricated units, permit fees, and in many cases an engineer’s letter. Here’s an honest breakdown of what drives the number.

A few factors specific to Boca Raton push costs toward the higher end of these ranges: oceanfront and Intracoastal properties require higher design-pressure ratings (PGT and ECO Window Systems both make units rated to meet those specs), historic district properties in Old Floresta may require design review approval before permits are issued, and CBS construction – which is the dominant wall type in most of Boca Raton – is more labor-intensive to cut than wood frame.

Our estimates are upfront and itemized. You’ll see exactly what the unit costs, what the labor costs, and what the permit costs – on one document, before any work begins. No surprises on the invoice.

Seniors and veterans get 10% off, permanently – not a seasonal promotion. If you already have a written estimate from another contractor, we’ll give you a free second opinion on it at no charge and no obligation.

Why Boca Raton Homeowners Choose Winslow for This Work

Oversized openings sit at the intersection of structural work, custom fabrication, and permit compliance. Most window companies handle one of those well. Fewer handle all three. Since 2011, Winslow Windows & Doors has been doing exactly that in Boca Raton, and Ed Winslow has been on the job – not managing it from an office across the state.

Ed’s name is on the door and on every job we do. When you call at any hour, a live person answers – not a recording, not a callback queue. Our technicians are background-checked and arrive in uniform. Before we pull into your driveway, you know who to expect.

We’re authorized installers for PGT, ECO Window Systems, and Mr-Glass, among others – brands that make units capable of meeting the wind-load and impact requirements for Boca Raton’s coastal zones. We don’t steer you toward what’s easiest for us to source; we specify what your opening and your location actually require.

And everything we do is backed by our 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. That’s not a warranty card in a drawer – it’s Ed’s word, and it’s the standard this company has held since we opened in 2011.

FAQs – Oversized Openings in Boca Raton

Do I need a permit to enlarge a window opening in Boca Raton?

Yes – any work that modifies a structural opening requires a permit from the City of Boca Raton Building Division before work begins. This includes enlarging an existing opening, combining two openings into one, or installing a custom unit in a new opening created during an addition. Palm Beach County enforces this consistently, and homes with unpermitted structural work can face problems at resale. We pull the permit as part of every oversized opening project we take on – you don’t have to navigate that process yourself. Call (561) 816-5648 if you want to talk through what your specific project will require.

How long does an oversized opening project take from start to finish in Boca Raton?

Most oversized opening projects take 6 to 12 weeks from signed contract to final inspection. The longest lead item is the Custom Impact Windows unit itself – PGT and ECO Window Systems typically build to order, and fabrication runs 4 to 8 weeks depending on the unit configuration. Permit processing with the City of Boca Raton currently averages 2 to 3 weeks. Once the unit arrives and the permit is in hand, the physical installation is usually a 1 to 2 day job. We give you a realistic timeline at the estimate stage so you can plan around it.

Can an oversized window in Boca Raton be impact-rated?

Yes, and in most of Boca Raton it needs to be. Florida Building Code requires impact-rated glazing or an approved storm protection system for all exterior openings. For oversized units, brands like PGT and ECO Window Systems fabricate large-format impact windows that meet the design pressure ratings required for your specific location – higher ratings apply east of Federal Highway and in coastal high-hazard zones. We specify the correct rating for your address during the measurement phase, so the unit that arrives is already code-compliant for your site. A non-impact oversized window in Boca Raton is not a legal installation.

What’s the difference between a standard window replacement and an oversized opening project?

A standard replacement swaps an existing window for a new one of the same size – no structural changes, simpler permitting, faster turnaround, and lower cost. An oversized opening project changes the size or position of the rough opening in the wall, which involves structural work (cutting and re-linteling CBS block, or reframing wood-stud walls), a structural engineer’s assessment in most cases, and a full building permit. The result is something no catalog window can fill – Geometric & Shaped Windows built to your exact dimensions. In Boca Raton, the price difference between a standard replacement and an oversized opening project typically runs $1,200 to $4,000 per opening, depending on wall type and unit size.
