AfterBay & Bow Windows in West Palm Beach, FL
Bay and bow windows in West Palm Beach typically run between $2,800 and $7,500 installed, depending on size, frame material, and whether impact-rated glass is part of the build. Most installations wrap up in one to two days, and yes – we pull the permits so you don’t have to chase them.
If you’ve been staring at a flat wall where a reading nook or dining alcove could be, a bay or bow window does two things at once: it adds square footage to the feel of the room and floods it with the kind of south Florida light that flat windows simply can’t replicate. At Winslow Windows & Doors, Ed Winslow has been overseeing these installations across Palm Beach County since 2011. Ed’s name is on the business, which means his reputation is on every measurement we take and every flashing detail we seal.

What Makes Bay and Bow Windows Different
A bay window projects out from the wall in three panels – a large center pane flanked by two angled side windows, typically set at 30 or 45 degrees, unlike casement windows which hinge at the side. The result is a structural bump-out that creates a genuine interior ledge or seat. A bow window uses four, five, or six panels arranged in a gentle curve, which softens the look on the outside and gives the interior more of a wraparound feel. Both styles are built to capture cross-ventilation when the operable side panels are open, which matters considerably in West Palm Beach’s long, humid summers.
The structural difference is worth understanding because it affects cost, framing, and the permit process. Bay windows require solid roof or knee-wall support beneath them – a detail that cheaper installers sometimes cut corners on, leading to sagging frames and water intrusion within a few years. Bow windows distribute load differently across more panels, which typically demands a steel or aluminum header above the opening. We frame every projection correctly the first time. That’s not a promise we make for marketing purposes – it’s why the Done Right Promise is actually possible to offer. If it’s not done right, we come back and make it right. Period.
In West Palm Beach neighborhoods like El Cid, Flamingo Park, and the historic corridors near Dixie Highway, we see a lot of older CBS construction homes where bay windows are installed to modernize the street-facing elevation. We also work regularly in newer developments in the Ibis and Ibis Golf and Country Club area where homeowners want more natural light-sometimes with garden windows or bay configurations-without sacrificing the impact ratings required by South Florida building code.
When You Need Bay or Bow Windows
- You want more usable floor space without an addition. A 24-inch projection on a bay window creates a genuine interior ledge – wide enough for seating, a plant shelf, or a reading nook. In West Palm Beach’s compact mid-century homes, this is often the most cost-effective square-footage gain available.
- Your existing windows aren’t impact-rated and hurricane season is approaching. If you’re replacing a single picture window anyway, stepping up to a framed bay or bow unit gets you the impact-rated glass South Florida requires while also gaining the architectural upgrade. ES Windows and CWS both manufacture impact-rated bay configurations we stock and install regularly.
- Natural light is an issue on a north- or west-facing wall. The angled panels of a bay window capture light across a wider arc than a flat window, which helps considerably in rooms that don’t face directly south or east.
- You’ve had moisture problems around a previous bay window. Improper flashing at the rooflet – the small roof section that caps a bay projection – is the single most common source of water intrusion we diagnose in West Palm Beach homes. If you’re seeing staining at the window head or on the ceiling above it, that rooflet needs to be pulled and redone correctly.
- You’re renovating for resale and want visible curb appeal. In Palm Beach County’s current market, a well-proportioned bay or bow window on the street-facing elevation is one of the few exterior upgrades that shows clearly in listing photos and adds perceived value before a buyer walks through the door.
- Your current unit is drafting, fogging, or has failed seals. Failed IGU seals are common in windows that are more than 15 years old, especially in our salt-air coastal climate. If the glass fogs between panes, the argon is gone and the thermal performance is compromised – that’s a replacement conversation, not a repair one.
Our Bay and Bow Window Installation Process
- Free on-site measurement and design consult. We don’t quote bay or bow windows over the phone – the projection depth, the structural header requirement, and the rooflet configuration all depend on what we see in person. Ed Winslow or one of our senior installers comes to you. We measure the rough opening, assess the framing condition, and talk through styles and frame materials that fit the home’s exterior profile. Upfront pricing – no surprises on the invoice – is what you get at the end of that visit.
- Permit application and product ordering. Bay and bow windows in West Palm Beach require a building permit, and we handle the paperwork. We pull permits in Palm Beach County and the city of West Palm Beach regularly, so we know exactly what the inspection checklist looks like. Products are ordered after permit approval, which protects you from having a window sitting in your garage while the county reviews the application.
- Structural prep and opening modification. Most bay and bow installations require enlarging the existing rough opening. We remove the old unit, assess the framing for rot or pest damage (common in older West Palm Beach construction near the water), install the correct header, and frame the projection support – either a knee wall below or a cantilevered support system, depending on the home’s structure.
- Window and rooflet installation. The window unit goes in plumb and level, shimmed and secured to the framing. The rooflet – the small shed-style roof cap above a bay projection – is flashed with aluminum step flashing and sealed with a Florida-product-approved sealant rated for our UV and heat exposure. This is the step that separates a properly done bay window from one that leaks in year three.
- Interior and exterior trim, insulation, and finishing. We insulate the projection cavity, install the interior seat board and side returns if included in the scope, and apply exterior trim that matches the home’s existing profile. We don’t leave gaps for a painter to figure out later.
- Inspection and final walkthrough. We schedule and pass the county inspection. Then we walk you through the finished window – how the operable panels work, how to clean the exterior from inside (a real quality-of-life issue on a second-story installation), and what the Done Right Promise covers going forward. If anything isn’t right at the walkthrough, it gets corrected before we leave.
Bay and Bow Windows Pricing in West Palm Beach
Bay and bow window costs in West Palm Beach span a meaningful range because the variables are real – window size, number of panels, frame material, glass type, structural modifications needed, and permit fees all move the number. Below are honest ranges based on what we actually see on Palm Beach County jobs.
| Configuration | Estimated Installed Cost |
|---|---|
| 3-panel bay window, standard frame, no structural modification | $2,800 – $4,200 |
| 3-panel bay window, impact-rated glass, aluminum or vinyl frame | $3,800 – $5,500 |
| 4- or 5-panel bow window, standard glass, full install | $4,200 – $6,000 |
| 4- or 5-panel bow window, impact-rated glass, full install | $5,200 – $7,500 |
| Structural header or framing modification (add-on) | $400 – $1,200 |
| Rooflet replacement or re-flash only | $600 – $1,500 |
| West Palm Beach building permit (typical) | $150 – $400 |
A few things that move costs higher in West Palm Beach specifically: homes near the Intracoastal or in older districts like Northwood have more wood rot in the framing than we find inland, which adds to structural prep time. High-humidity salt-air environments also require aluminum-clad or full fiberglass frames to hold up over the long term – vinyl alone degrades faster here than manufacturers’ mainland ratings suggest. And if your home still has single-pane windows, Florida building code now requires impact or storm-protection compliance on any new window installation, so impact glass is often not optional. Horizontal roller windows are another option we see requested for modern replacements, though bay and bow configurations remain popular for the character they add.

FAQs – Bay and Bow Windows in West Palm Beach
Do bay and bow windows require a building permit in West Palm Beach?
Yes – any window installation that involves enlarging an opening or adding a structural projection requires a building permit in West Palm Beach and Palm Beach County. Winslow Windows & Doors pulls the permit on your behalf, handles all the county paperwork, and schedules the required inspection. You don’t need to set foot in the permit office. This is included in the project scope – it’s not a surprise add-on at the end. Call (561) 660-9539 and we’ll walk you through what the permit process looks like for your specific address.
Do bay and bow windows need to be impact-rated in West Palm Beach?
In most cases, yes. West Palm Beach falls within the High-Velocity Hurricane Zone (HVHZ) under Florida Building Code, which means any new window installation must meet impact or approved storm-protection standards. A standard bay or bow window without impact glass does not satisfy this requirement, and it will not pass inspection. CWS and ES Windows both manufacture impact-rated bay and bow configurations we install regularly in Palm Beach County – these are the same units that meet Florida Product Approval requirements. If you’ve received a quote for a non-impact bay window in this area, ask the contractor how they plan to handle the inspection. Call us at (561) 660-9539 and we’ll give you a straight answer on what your specific project requires.
How long does a bay or bow window installation take?
Most bay and bow window installations in West Palm Beach take one full day on-site once the permit is in hand and the product arrives. Larger bow configurations with five or six panels, or jobs that require significant framing modification, may run into a second day. The permit process – application, review, and approval – typically adds two to four weeks before the installation day, which is normal and unavoidable for permitted work in Palm Beach County. We give you a realistic timeline at the estimate stage, not an optimistic one. Call (561) 660-9539 to get a timeline estimate specific to your project scope.
What is the Done Right Promise, and does it cover bay windows?
The Done Right Promise is Winslow’s warranty commitment: if the work isn’t done right, we make it right. It applies to all of our installations, including bay and bow windows – that means the structural framing, the rooflet flashing, the window unit itself, and the interior and exterior finish work. It’s not a limited warranty that carves out labor after one year or materials after five. Ed Winslow’s name is on every job, and that kind of accountability doesn’t come with an asterisk. If you have questions about what the Promise covers on a specific scope of work, call (561) 660-9539 and Ed or a senior team member will talk through it with you directly.
