Bay & Bow Windows in Fort Lauderdale, FL

Bay & Bow Windows in Fort Lauderdale, FL

Bay and bow window installation in Fort Lauderdale runs $1,800 to $6,500 per unit installed, depending on the configuration, frame count, glazing spec, and whether impact-rated glass is required. Most projects in Broward County require impact-rated glazing under the Florida Building Code, so that cost is almost always part of the number you’ll see on your written scope – not a line item that appears later. At Sightline Windows & Doors Fort Lauderdale, every engagement starts with a measured survey the customer keeps, and the written price cannot differ from that document. That’s Haven Clause 1.

Bay and bow windows are projection windows: they extend outward from the wall plane, creating a recessed interior shelf and a wider sightline to the outside. A bay window uses three panels set at angles – typically a fixed center lite flanked by two operable casement windows or double-hung units at 30 or 45 degrees. A bow window uses four or more panels of equal width arranged in a gentle curve. Both add square footage to the perceived interior, bring in significantly more daylight than a flat wall window, and add visual weight to a facade that a single flat unit cannot match. In Fort Lauderdale’s older neighborhoods – Victoria Park, Edgewood, Coral Ridge – we see a lot of these installed in front living rooms and master bedrooms where homeowners want the look without losing the storm protection they need to carry homeowners insurance.

If you’re researching what’s involved before making contact, you’re in the right place. Our Window Installation in Fort Lauderdale page covers the full scope of what we install and how we price it. This page goes deeper into bay and bow specifically – the structural considerations, the glazing options from lines like CGI and CWS, and the documented process that every Sightline installation follows under the Haven Standard.

When You Need Bay or Bow Windows

• You’re replacing a single flat window that under-lights the room. In Fort Lauderdale homes with deep overhangs – common in ranch-style builds in Lauderdale Lakes and Lauderdale Manors – a standard flat unit sits in shadow for much of the day. A bay or bow projection moves the glass plane outward past the overhang line, picking up direct light that a flat replacement never would.
• Your existing bay or bow unit is fogged, rotted, or out of square. Older aluminum-framed bay units from the 1980s and 1990s are common in Fort Lauderdale’s mid-century stock. When the frame corners separate or the sealant between the roofline and the projection box fails, water tracks into the wall cavity – sometimes for months before the interior shows staining. We document every frame condition with photos before we remove anything.
• You need to bring the opening into hurricane-mitigation compliance. If your bay or bow unit was installed before Florida’s current impact-glazing standards, it may not meet current Broward County code. Non-compliant windows can complicate insurance renewal and resale inspections. CGI and CWS both manufacture impact-rated bay configurations that meet Miami-Dade Notice of Acceptance (NOA) standards – and those specifications go into your written scope by product number, not by brand name alone.
• You’re adding a bay or bow to a new or modified opening. New openings require a Broward County structural permit and a licensed contractor of record. Sightline holds the licenses required to pull that permit and serve as contractor of record – the license number is on the page before a tool is lifted, per Haven Clause 3 (Verified Crews).
• The seat board or knee wall beneath an existing unit is failing. Bay and bow windows include a structural seat – a framed knee wall or cantilevered platform that carries the projection load. In Fort Lauderdale’s humidity, untreated wood in that knee wall rots quietly. We inspect and document that assembly during the measured survey, not after demo.
• You want more usable interior space without an addition. A bay projection adds 12 to 18 inches of interior depth at the window seat – enough for built-in storage or seating in a front room or master bedroom. Several homeowners in Wilton Manors and Rio Vista have used that projection to frame a reading nook that didn’t require a permit-level room addition.

Our Bay & Bow Windows Process

1. Measured Survey and Written Scope
   A Sightline technician – background-checked, uniformed, and identified by license number before arrival – visits the opening and takes frame-to-frame measurements: rough opening width and height, wall depth, exterior projection clearance, roofline clearance, and knee wall or sill condition. We note the current glazing spec (U-factor, SHGC if readable), frame material, and any visible water intrusion. You receive a copy of this survey. The written quote is built from this document and cannot deviate from it.
2. Product Specification by Opening, Not by Inventory
   We carry eight manufacturer lines. For bay and bow work in Fort Lauderdale, the relevant impact-rated options come primarily from CGI, CWS, and ES Windows – each with different frame depth profiles, sightline dimensions, and color palettes. We specify by what the opening requires: U-factor at or below 0.40 for Energy Star compliance in Climate Zone 1, SHGC at or below 0.25 for west- and south-facing exposures, and Miami-Dade NOA compliance for impact glazing. You see the product number, the spec sheet reference, and the installed price – all on the same document.
3. Permit Pulled Before Scheduling Installation
   For new openings or structural modifications, we pull the Broward County permit before we schedule the installation date. For like-for-like replacements in existing rough openings, we confirm the permit category and notify you in writing before proceeding. No work starts without the permit category confirmed on your written scope.
4. Structural Framing and Projection Assembly
   Bay and bow installation is not a straight window swap. The projection box – including the roof section above and the knee wall or seat board below – must be framed, flashed, and sealed as a single weather-tight assembly. We use pressure-treated framing lumber at the seat, self-adhering flashing membrane at all horizontal transitions, and backer rod with low-modulus sealant at the perimeter before the trim cap goes on. In Fort Lauderdale’s rainfall pattern – averaging 62 inches per year, with most of it arriving as high-velocity wind-driven rain between June and October – that flashing detail is not optional.
5. Glazing Installation and Frame Alignment
   The individual lites are set into the assembled frame, shimmed plumb and level, and secured per the manufacturer’s installation instruction (which we keep on file by job). For impact-rated units, the glazing bead and bite dimensions are set to the NOA specification – not field-improvised. We check every operable sash for smooth operation and verify that the locking hardware engages fully before we move to finishing work.
6. Documented Photo Record and 365-Day Done Right Promise
   When the installation is complete, we photograph the finished unit from the exterior and interior, the perimeter sealant line, the roofline flashing, and the knee wall assembly. Those photos are your documented evidence under Haven Clause 4 (Evidence on Every Job). The 365-Day Done Right Promise covers the installation workmanship from that date: if something isn’t right, we make it right – written into the Haven Standard, not offered verbally.

Bay & Bow Windows Pricing in Fort Lauderdale

Bay and bow windows cost more than flat replacements or horizontal roller windows because they involve more glass, a structural projection assembly, and – in almost every Fort Lauderdale installation – impact-rated glazing. Below are the ranges we see in practice. These are installed prices: product, labor, structural framing, permit (where required), and sealant work are included. The number on your written scope reflects your specific opening – these ranges tell you where to expect to land before you call.

What moves the number up or down:

• Frame material – aluminum impact frames sit at a lower price point than fiberglass or wood-clad; in Fort Lauderdale’s salt-air coastal zones (Lauderdale-by-the-Sea, Harbor Beach, Riviera Isles), aluminum with a marine-grade finish is often the right call for corrosion resistance.
• SHGC specification – west and south exposures in Fort Lauderdale carry a real heat-gain penalty; specifying SHGC at 0.19 rather than 0.25 adds cost at the glass level but reduces cooling load measurably.
• Seat board and knee wall condition – we photograph and document what we find before demo; if the existing seat board is sound, that cost doesn’t appear on your scope.
• Permit category – like-for-like replacement in an existing opening is often a simpler permit path than a new or modified opening; we tell you which category applies before you commit.
• Interior trim and finish work – if you want the seat board finished with a hardwood cap or the interior casing replaced to match existing millwork, that’s a line item we can include or exclude on your written scope.

Estimates are free, written, and reflect the actual measured survey – not a phone approximation. Call (754) 666-7478 or bring us a competitor’s written estimate; we’ll review it at no charge under our Free Second Opinion policy.

FAQs – Bay & Bow Windows

Do bay and bow windows in Fort Lauderdale need to be impact-rated?

Yes, in nearly every residential application. Florida Building Code Section 1609 and Broward County’s local amendments require that all fenestration in the wind-borne debris region meet impact-resistance standards or be protected by an approved shutter system. Most lenders and insurers writing policies in Fort Lauderdale’s coastal and near-coastal zones – which covers the majority of the city – require impact glazing on any window replacement or new installation. CGI and CWS both manufacture bay and bow configurations with Miami-Dade NOA product approvals; we specify those by product number on your written scope. If you’re unsure whether your existing unit meets current code, call (754) 666-7478 and we’ll confirm during the measured survey at no charge.

How long does a bay or bow window installation take in Fort Lauderdale?

Most single-unit bay or bow replacements in an existing rough opening take one to two days on-site: one day for structural framing, flashing, and projection assembly, and a second day if the glazing units require a separate delivery window or if interior trim work is included. New openings with permit-required structural modifications can extend the schedule by two to four weeks on the front end while the permit processes through Broward County. We give you a documented installation date before any work starts – Haven Clause 2 (Arrive on Schedule) – so you’re not waiting on an estimate of an estimate.

What is the difference between a bay window and a bow window, and which one is right for my Fort Lauderdale home?

A bay window uses three panels – a fixed center lite and two flanking units set at 30 or 45 degrees, creating a sharp angular projection. A bow window uses four or more panels of equal width arranged in a smooth curve. Bay windows are the more common choice in Fort Lauderdale’s mid-century and ranch-style homes because the angular geometry fits the flatter rooflines of that era; bow windows work well on two-story facades in neighborhoods like Coral Ridge or Colee Hammock where the exterior elevation has enough height to carry the curve. The right choice is also partly structural: a bow window distributes load differently across the projection and requires more precise framing alignment. We’ll note which configuration the opening and facade suit better on the written scope, with the reasoning documented, not just asserted.

Can I add a bay or bow window to a wall that doesn’t currently have one?

Yes, but it requires a structural assessment and a Broward County permit. Cutting a new opening in a load-bearing wall – which is common in Fort Lauderdale’s CBS (concrete block and stucco) construction – means addressing the header, the masonry lintel, and the exterior wall assembly in a documented scope. Sightline holds the required contractor licenses to pull that permit and serve as contractor of record; the license numbers are on your written scope before work begins. The cost range for new-opening bay and bow installations starts around $4,500 and moves up with wall construction type, opening size, and finish work. Call (754) 666-7478 for an on-site measured survey – that’s the only way to give you a number that holds.
