AfterBay & Bow Windows in Palm Beach, FL
Bay and bow windows are among the most requested upgrades we install in Palm Beach – and for good reason. They push outward from the wall to create a recessed interior shelf, flood the room with natural light, and add genuine architectural character that flat windows simply can’t match. At Winslow Windows & Doors, we’ve been installing bay and bow windows across Palm Beach since 2011, and every one of those jobs carries Ed Winslow’s name on it.
If you’re ready to talk specifics, call us at (561) 831-7863 – a live person picks up every time, day or night. Or start here: our full Window Installation in Palm Beach page gives you a broader look at everything we do for Palm Beach homeowners.
Bay windows typically feature a center picture window flanked by two angled casement or double-hung units, while bow windows use four to six equally spaced windows curved into a gentle arc. Both configurations are popular in Palm Beach’s older Mediterranean Revival and Colonial-style homes, where the original single-pane units have long since given up the fight against humidity, salt air, and UV exposure. Installing either style isn’t a cosmetic project – it involves structural framing, exterior trim work, proper flashing, and, in most cases, impact-rated glazing to satisfy Palm Beach County’s building code. That’s exactly the kind of full-scope job we do well.
When You Need Bay & Bow Windows
- Your existing window wall feels closed-off or dark. In Palm Beach’s narrower historic homes – especially older cottages in El Cid and Flamingo Park – a bay or bow projection can turn a dim sitting room into the most inviting space in the house without touching the roofline or adding square footage.
- You’re replacing failed single-pane or aluminum-framed units. Aluminum frames corrode fast in coastal salt air, and single-pane glass offers almost no thermal resistance. We regularly pull out 30- and 40-year-old aluminum bay windows in South Palm Beach neighborhoods and replace them with impact-rated, low-E units that actually hold up to the climate.
- You want a built-in window seat or interior shelf. The angled projection of a bay window creates a natural platform. Clients in Palm Beach Shores frequently ask for this specifically – it’s a practical upgrade, not just a visual one.
- Your current bay or bow is leaking around the frame. Improper flashing at the roof cap – the small shed roof that covers the projection – is the number-one moisture entry point we find during inspections. Left alone, that leak damages the interior framing, drywall, and flooring below. Catching it early is a fraction of the remediation cost.
- Your home is going through a renovation or addition. If walls are already open, that’s the right time to rough in a bay or bow window. We coordinate with general contractors across Palm Beach County so the framing, permit, and window delivery line up – not after the fact.
- You’re preparing to sell. Bay and bow windows are a visible curb-appeal item that buyers notice before they step inside. In Palm Beach’s competitive real estate market, the difference shows in listing photos.
Our Bay & Bow Windows Process
- In-home consultation and measurement. Ed or one of our uniformed, background-checked technicians visits the home to take precise measurements of the existing opening and assess the wall framing, interior trim, and exterior siding. We look at the soffit overhang, confirm what’s behind the drywall, and check for any prior moisture damage. You’ll get a written, itemized estimate before we leave – upfront pricing, no surprises on the invoice later.
- Product selection and permit filing. We help you choose the right configuration – bay versus bow, window count, frame color, glass type – and match it to a product that fits your home and budget. For most Palm Beach homes, that means an impact-rated unit from PGT or CGI. Once you approve the quote, we pull the Palm Beach County building permit. No homeowner should be doing their own permit pull on a structural window installation – we handle it entirely.
- Structural framing and opening preparation. Bay and bow windows require a load-bearing header above the opening. We frame or reinforce as needed, remove the old unit, and address any rot or moisture damage in the rough opening before the new window goes in. This step separates a proper installation from one that fails in three years.
- Window installation and flashing. The window assembly is set, leveled, and anchored to the structural frame. The roof cap – typically a small shed roof with metal flashing – is installed over the projection and sealed to the exterior cladding. Flashing detail here is non-negotiable. Palm Beach gets 60-plus inches of rain in a normal year, and every gap in the flashing is an invitation for water intrusion.
- Interior and exterior trim finish. We build out the interior window seat platform and side trim, and match the exterior casing to the existing profile as closely as possible. The goal is for the window to look like it was always there – not like an addition someone tacked on.
- Final inspection and walk-through. We schedule the county inspection, stay on-site while it’s conducted, and walk you through the completed work before we leave. If anything isn’t right, we fix it before the job is closed – that’s the 36500-Day Done Right Promise in practice, not just in print.
Bay & Bow Windows Pricing in Palm Beach
Bay and bow window installations in Palm Beach typically run between $2,800 and $8,500 per unit, installed. That’s a wide range, and the variables below explain most of it. These are real numbers for the Palm Beach market – not low-ball figures designed to get a truck in your driveway.
| Project Type | Typical Installed Cost Range |
|---|---|
| Standard 3-lite bay window (vinyl, non-impact) | $2,800 – $4,200 |
| Impact-rated 3-lite bay window (PGT or CGI) | $4,500 – $6,500 |
| 4- or 5-lite bow window (impact-rated) | $5,500 – $8,500 |
| Structural header reinforcement (if needed) | $400 – $900 additional |
| Rotted framing or moisture remediation | Priced per scope after inspection |
What moves the number up or down
- Impact rating: Palm Beach County sits in a High-Velocity Hurricane Zone (HVHZ), and most homeowners within a mile of the Intracoastal or ocean need impact-rated units to satisfy both code and insurance requirements. Impact glass adds cost but removes the need for hurricane shutters – a trade-off most Palm Beach homeowners find worthwhile.
- Frame material: Vinyl is the most common choice and holds up well in coastal humidity. Fiberglass frames carry a higher price point but offer better rigidity over large spans, which matters for wider bow configurations.
- Existing opening size and structural condition: A window going into a standard 5-foot opening costs less to frame than one expanding into a 9-foot span. We price the structural work separately and transparently.
- Roof cap complexity: Simple shed roofs are straightforward. Vaulted or copper-capped designs – more common in Palm Beach’s historic Phipps estate and North End properties – require more time and material.
- Interior finish work: A basic seat platform and painted trim is included. Custom millwork to match original 1920s profiles costs more and is priced after we see the existing trim.

Why Palm Beach Homes Need Impact-Rated Bay and Bow Windows
This is worth saying plainly: a standard bay or bow window – the kind you’d install in Orlando or Atlanta – is not appropriate for most Palm Beach properties. The Florida Building Code’s HVHZ requirements apply broadly to Palm Beach County, and any window installation that doesn’t meet the local wind-load and impact standard will fail inspection and create insurance problems.
Beyond code, the physics are simple. A large bay or bow projection has more exposed glass surface than a standard flat window. In a Category 2 or 3 storm, that glass takes a direct beating. Impact-rated units from manufacturers like PGT and CGI use laminated glass bonded to a strong inner membrane – if the outer pane cracks, the inner membrane holds. The frame stays intact. The house stays pressurized. That’s not a marketing claim; it’s the engineering principle behind HVHZ approval.
We’ve inspected bay window installations in Palm Beach where the previous contractor used non-impact units and framed them into a large opening without proper structural headers. One in the Lake Worth Beach area had visible racking – the frame had shifted slightly in the opening over several storm seasons. We rebuilt the opening, installed a proper header, and put in a PGT impact unit. The homeowner had been living with fogged glass and air leaks for four years before calling us.
If you’re getting a second opinion on a written estimate, we offer that free of charge – no obligation, no sales pressure. Call (561) 831-7863 and we’ll take a look.
FAQs – Bay & Bow Windows
How much does a bay or bow window cost in Palm Beach?
A bay or bow window installation in Palm Beach typically costs between $2,800 and $8,500 installed, depending on size, frame material, and whether impact-rated glass is required – which it usually is for homes in Palm Beach County’s HVHZ designation. The largest single variable is impact rating: a non-impact bay window might come in at $3,000, while a comparably sized impact-rated unit with proper structural framing runs $5,000 or more. Call (561) 831-7863 for a free, written estimate specific to your home.
Do bay and bow windows require a permit in Palm Beach?
Yes. Any bay or bow window installation in Palm Beach that involves structural modification – which is essentially all of them, because these windows require a load-bearing header – requires a Palm Beach County building permit. We pull the permit as part of every installation. Homeowners who skip the permit face problems at resale and potential insurance claim denials after a storm. We handle the permit process entirely, including scheduling and attending the final county inspection.
How long does a bay or bow window installation take?
Most bay or bow window installations in Palm Beach take one to two days of on-site work, not counting the permit lead time. The permit process in Palm Beach County currently runs two to four weeks from submission, so plan for three to five weeks from signed contract to completed installation. Larger projects involving multiple units or significant framing work may run longer. We give you a realistic timeline in writing before the job starts – not a number designed to win the bid.
Can a bay or bow window be impact-rated for hurricane protection?
Yes, and for most Palm Beach properties it’s the right choice. Impact-rated bay and bow windows use laminated glass assemblies that meet HVHZ standards and satisfy both the Florida Building Code and most insurance carrier requirements for storm protection. Brands like PGT and CGI manufacture impact-rated bay and bow configurations specifically for coastal Florida conditions. Installing impact windows also eliminates the need to deploy hurricane shutters over the projection every storm season – which, for a large bay window or garden windows, is genuinely difficult to do correctly. Call (561) 831-7863 for specifics on which configurations are available for your home’s opening.
