AfterOversized Openings in Fountainebleau, FL
Installing an oversized window opening in Fountainebleau typically runs between $1,800 and $6,500 per opening, depending on framing complexity, impact-rating requirements, and the size of the unit. Most jobs we schedule are completed within one to two days once the product is on hand. If your home has a grand entryway, a two-story great room, or a wide wall that deserves more than a standard 3-foot unit, we handle the structural modifications, product sourcing, and installation as part of our Custom & Geometric Windows services.
At Winslow Windows & Doors, Ed Winslow has been working on homes like yours in Fountainebleau since 2011. Oversized openings are not a niche we dabble in occasionally – they sit at the heart of our Custom & Geometric Windows in Fountainebleau service. Every project carries Ed’s name and our Done Right Promise: if it’s not done right, we come back and make it right. That’s not a limited-time pledge – it’s the standard we’ve held since we opened. Call us at (727) 620-6983 any time, day or night, and a live person will answer.
When You Need Oversized Openings
Not every home in Fountainebleau is a candidate for an oversized opening, but more are than most homeowners realize. Here are the situations we see most often:
- New construction or major remodel with a statement wall. Builders in the Hammocks and Doral-adjacent corridors near Fountainebleau are regularly spec’ing 6-foot and 8-foot wide window bays where a standard double-hung simply won’t fill the opening. We work directly with contractors and homeowners to size and frame these correctly from the start.
- Existing opening that’s too narrow for the view you want. Many CBS homes in the area were built in the 1970s and 1980s with 36-inch rough openings. If you’re remodeling a living room that faces west toward a canal or green space, widening that opening to 60 or 72 inches transforms the room without requiring a full addition.
- Impact-code upgrade on a large picture window. Fountainebleau falls inside Miami-Dade County’s High-Velocity Hurricane Zone (HVHZ). Any window over a certain size – particularly picture and fixed-glass units – must meet stringent Miami-Dade NOA (Notice of Acceptance) requirements. We source HVHZ-compliant oversized units from ECO Window Systems, both of which carry the required product approvals for large-format installations.
- Sliding glass door opening converted to a window wall. We regularly get calls from homeowners in the Sweetwater and Bird Road Farms areas who closed off an old patio and want to replace a sliding door rough opening with a wide, fixed-glass or casement window. The framing is already wider than standard – it just needs the right product to fill it properly.
- Second-story or vaulted ceiling applications. Two-story foyers and vaulted great rooms create openings that are both wide and tall. Standard catalog windows top out around 48 inches in height; oversized fabrication takes you to 72 inches or beyond. We coordinate safe staging and lift equipment for any second-story work.
- Insurance replacement after storm damage. Miami-Dade County’s weather history is not abstract in Fountainebleau. When a large original window fails in a storm and the replacement must meet current HVHZ code, the original undersized unit often can’t be reinstalled. We handle the scope documentation, product selection, and installation so the insurance process doesn’t stall.
Our Oversized Openings Process
We don’t hand you a catalog and disappear. Here is exactly what happens from first call to final inspection:
- On-site measurement and structural assessment. Every oversized opening project starts with Ed or one of our background-checked, uniformed technicians coming to the home for a full measurement. We check the rough opening dimensions, assess the lintel or header above the opening, and evaluate the wall type – CBS block, wood frame, or hybrid – to determine what structural modifications are needed before we touch anything. This visit is free, and there is no trip charge inside Miami-Dade County.
- Product selection and NOA confirmation. Once we know the opening dimensions, we identify the right unit from our authorized brand lineup. For most oversized applications in Fountainebleau, ECO Window Systems are our first calls – both carry Miami-Dade NOA approvals for large-format, impact-rated configurations. We confirm the specific product approval before ordering, so there are no surprises at inspection.
- Upfront written pricing and permit filing. You receive a line-item written estimate before we order a single piece of material. Our pricing is upfront – what you see is what you pay. We pull all required Miami-Dade County building permits, which is non-negotiable for any structural window modification in Fountainebleau. Homeowners who attempt to skip permitting on oversized openings regularly face resale complications and insurance claim denials; we won’t let that happen on our jobs.
- Structural preparation and framing. Depending on the scope, this step involves reinforcing or replacing the header above the opening, widening or enlarging the rough opening in the wall, and confirming that the finished dimensions are within the tolerance the product manufacturer requires for a valid product warranty. This is precision work – a header that’s undersized for the span can cause long-term deflection that binds the window over time.
- Impact window installation and sealing. Our technicians install the unit using manufacturer-specified anchoring, flashing tape, and sealant. For HVHZ-compliant installations, the anchor pattern, embedment depth, and sealant bead are not optional steps – they’re part of the NOA. We document the installation to support the permit inspection and to protect you if a future insurance claim requires proof of compliance.
- County inspection and final walkthrough. After installation, we coordinate the Miami-Dade County inspector visit and walk through the finished project with you. We don’t consider the job closed until you’ve seen the product operate, understood the cleaning and maintenance expectations, and confirmed you’re satisfied. The Done Right Promise covers the installation from that point forward.
Oversized Openings Pricing in Fountainebleau
Oversized openings in Fountainebleau run higher than standard window replacements, and the reasons are straightforward: larger glass, heavier frames, additional structural work, and Miami-Dade NOA-compliant hardware all add to the project cost. Here’s an honest look at what affects your number:
| Scope | Typical Range (Installed) |
|---|---|
| Wide picture window (60″-72″ wide, existing opening) | $1,800 - $2,800 |
| Wide picture window with minor framing modification | $2,400 - $3,600 |
| Large casement or fixed unit (72″+ wide or 60″+ tall) | $2,800 - $4,200 |
| Full structural opening enlargement + large unit | $3,500 - $6,500 |
| Two-story or vaulted application with lift equipment | $4,200 - $7,500+ |
A few things that move your number up or down:
- Wall construction. CBS block walls – common throughout Fountainebleau – require core drilling and anchor installation that adds time and labor compared to wood-frame walls.
- Header replacement. If the existing lintel over your opening was sized for a narrower span, replacing it is a structural requirement, not an upsell. We tell you before we start, not after.
- Impact vs. non-impact glass. Inside HVHZ, impact-rated glass is code-required on most openings. Non-impact product is generally not a legal option for new or enlarged openings in Fountainebleau. We won’t quote you a non-compliant product just to show a lower number.
- Product tier. ECO Window Systems both carry HVHZ approvals for large-format units; ECO’s aluminum series tends to run slightly lower than ViewLux’s premium thermally broken line. We’ll walk you through the tradeoffs so you can decide based on budget and long-term energy performance.
- Permit fees. Miami-Dade County permit fees for structural window work vary by valuation. We include the permit cost in the estimate so you’re not surprised by a separate invoice from the county.

FAQs – Oversized Openings
Can I install an oversized window in my Fountainebleau home without a permit?
No – any structural modification to a window opening in Fountainebleau requires a Miami-Dade County building permit, and skipping it creates serious problems. Unpermitted structural work can void your homeowner’s insurance, trigger a stop-work order if discovered, and create title issues when you sell. HVHZ compliance is also verified at the permit inspection, so an unpermitted oversized opening may not be certifiably impact-rated even if the glass technically is. We pull permits on every job, no exceptions. Call us at (727) 620-6983 if you’re unsure what your project requires – we’re happy to talk through it at no cost.
How wide can an oversized window opening realistically get in a CBS home?
In CBS block construction, practical limits are determined by the header span and the structural capacity of the surrounding block. Most residential openings in Fountainebleau top out around 96 to 120 inches (8 to 10 feet) before the engineering requirements become significant for Arched & Curved Windows and other custom shapes. Above that width, you’re generally looking at engineered steel lintels and potentially a structural engineer’s sign-off. We’ve installed units in the 84-inch range in CBS homes throughout the area without major structural concerns; anything wider gets a detailed assessment before we quote. Call us at (727) 620-6983 and we’ll evaluate your specific wall on-site.
How long does an oversized opening project take from start to finish in Fountainebleau?
From signed contract to completed installation, most oversized opening projects in Fountainebleau take three to six weeks. The largest variable is product lead time – large-format, Custom Impact Windows from ECO Window Systems or ViewLux typically run two to four weeks from order confirmation. Once the unit arrives, the installation itself usually takes one to two days depending on structural scope. Permit scheduling with Miami-Dade County adds time too, though we file promptly and track the permit status so the project doesn’t sit waiting. We give you a realistic timeline upfront, not an optimistic one that slips later.
Is it worth widening an existing opening, or should I just replace the current window?
Widening an existing opening is worth it when the current size genuinely limits light, ventilation, or the view – and when the wall construction allows it without prohibitive structural cost. In Fountainebleau, where west-facing living rooms often overlook canals or green spaces, a 24-inch wider opening with Geometric & Shaped Windows can dramatically change how a room feels. If the existing opening is already an appropriate size and the window is simply old or non-impact, a straight replacement costs less and still solves the code compliance and energy performance issues. We’ll give you an honest read on whether enlargement pencils out for your specific situation – we’d rather you spend the right amount than the maximum amount.
