AfterBay & Bow Windows in Weston, FL
Bay and bow windows in Weston, FL typically run between $2,800 and $7,500 installed, depending on unit size, glass configuration, and whether impact-rated glazing is required. Most projects are scoped and quoted in a single measured survey, and every written price Sightline Windows & Doors Weston puts on paper before work starts is the same number on the final invoice.
If you’re replacing a flat window with a bay or bow projection, or you’re building out a new opening entirely, the work is more involved than a standard single-unit swap. The framing has to be right, the roofline or soffits above the projection need to be addressed, and in Weston’s climate, the glazing spec matters year-round. We’ve handled this type of Window Installation across Weston’s neighborhoods – from older homes in Bonaventure to newer construction near Weston Hills Country Club – and the variables we see here don’t always match what a national installation guide would tell you to expect.
Call us at (754) 812-9260 to schedule your measured survey. Calls are answered by a live person, 24/7 – no voicemail queue, no callback window. Or keep reading to understand exactly what goes into a bay or bow window installation in Weston before you decide anything.
Bay and bow windows are a sub-service of our broader Window Installation in Weston offering, which covers everything from single-unit replacements to full-home reglazings under the Haven Standard.
When You Need Bay or Bow Windows
Not every project is obvious from the outside. Here are the situations where homeowners in Weston typically contact us about bay and bow windows:
- You want to expand natural light without a full addition. A standard flat window is limited by the rough opening. A bay or bow projection extends outward 12 to 24 inches, pulling in light from three or more angles and making a room feel larger without changing the floor plan. In Weston’s single-story ranch-style homes, this is one of the most common requests we get.
- Your existing bay or bow unit is leaking or fogging between panes. Older bay windows in Weston – especially units installed before 2000 – often used aluminum framing with no thermal break, and the silicone seals around the angled side units deteriorate in South Florida heat. Fogging between panes means the insulating gas seal has failed and the unit needs to be replaced, not resealed.
- You’re missing impact-rated glazing on a bay projection. In Weston, any window that faces wind exposure must meet Miami-Dade Notice of Acceptance (NOA) requirements for impact performance, or be protected by storm shutters. Older bay units rarely carry current NOA approval. If your bay window can’t produce a product approval number, it may not pass a resale inspection – and replacing it with a compliant impact-rated unit is the cleaner path forward.
- The framing around your existing bay unit is rotting or compromised. The header, seat board, and knee wall beneath a bay projection take on more structural load than a flat window frame. In Weston’s wet season, water intrusion at the roofline above the projection is the leading cause of wood rot we find during our measured surveys. Replacing only the glass unit without addressing the framing is a short-term fix.
- You’re remodeling and want to replace a sliding glass door opening with a window feature. Some Weston homeowners converting an enclosed porch or lanai choose to close a former door opening with a bow window to maintain the view while adding insulation value. This requires framing work that a standard window replacement doesn’t.
- Your current bay window is undersized for the room and creates a cold spot in winter. Weston’s winters are mild, but overnight temperatures do drop into the low 50s and occasionally the 40s. A poorly sealed or single-glazed bay unit can create a noticeable cold spot along an exterior wall, which becomes a humidity problem when the air conditioning runs.
Our Bay & Bow Windows Process
Every bay or bow window project at Sightline follows the same documented sequence. Nothing starts until the written price is in your hands, and nothing is closed out until the photo record is complete.
-
Measured Survey and Written Scope
A uniformed, background-checked Sightline technician arrives at your home in Weston and takes full measurements of the rough opening, the wall depth, the exterior projection clearance, and the roofline or soffit above the bay or bow location. We read the framing condition, check for existing water intrusion, and confirm what product approval documentation will be required for permit. You receive a written scope document you keep – this is the same document the final invoice is drawn from. Haven Clause 1: the price is in writing before any work starts.
-
Product Selection and Impact Rating Confirmation
Based on the opening size, wall depth, and your design preferences, we specify a unit from one of our manufacturer lines – CWS and ES Windows both carry strong impact-rated bay and bow configurations suited to Weston’s wind load requirements, along with Casement Windows options when operable side lites are preferred. We’ll confirm the Miami-Dade NOA number for the specified product and document it in your written scope. SHGC (solar heat gain coefficient) matters here: in Weston, a south or west-facing bay window with an SHGC above 0.25 will add measurable heat load to the room, so we’ll flag the glazing spec in plain English alongside the product approval numbers.
-
Permit Pulling and Scheduling
Bay and bow window installations in Weston require a building permit through the City of Weston Building Division when the work involves structural framing changes – which it almost always does when installing a projection unit into a previously flat opening. Sightline pulls the permit; you don’t manage that step. We coordinate the inspection schedule so you know the date before we start.
-
Removal and Framing Preparation
The existing unit is removed and the rough opening is inspected in place. If we find framing damage or water intrusion that wasn’t visible during the survey, we stop and call you before doing anything. Haven Clause 5: no surprises. Any scope change is written before it’s executed, and the price is updated in the same document.
-
Installation, Sealing, and Flashing
The new bay or bow unit is set, leveled, and shimmed. The head flashing above the projection – the single most common failure point on bay windows in Weston’s rainy season – is installed per the manufacturer’s flashing instructions and our own Haven Standard protocol. All interior and exterior trim is finished before we call the job complete.
-
Inspection, Photo Record, and 365-Day Warranty
The city inspector signs off. We photograph the finished installation – interior frame, exterior trim, flashing detail, and glazing condition – and that photo record is filed to your job record. The 365-Day Done Right Promise covers every installation under the Haven Standard: if it’s not right, we make it right, in writing, not as a courtesy.

AfterBay & Bow Windows Pricing in Weston
Bay and bow Garden Windows installations in Weston range more widely than most window projects because the scope varies significantly by opening type, projection style, and framing condition. The table below reflects what Sightline sees in Weston specifically – not national averages.
| Scope | Typical Installed Range (Weston, FL) |
|---|---|
| Bay window replacement (existing opening, no framing changes) | $2,800 – $4,200 |
| Bay window replacement (existing opening, framing repair required) | $3,500 – $5,500 |
| Bow window replacement (4-5 lite, existing opening) | $4,200 – $6,500 |
| New bay or bow opening (wall cut, full framing, structural header) | $5,500 – $7,500+ |
| Impact-rated glazing upgrade (added to any tier above) | $300 – $900 per unit |
| Permit fee (City of Weston, typical range) | $175 – $400 |
What Moves the Price in Weston
- Projection depth and number of lites. A standard bay window has three glass sections (one fixed center, two operable side units angled at 30 or 45 degrees). A bow window has four to six lites in a curved configuration. More lites mean more linear footage of frame, more glazing area, and more sealing detail at each joint.
- Impact rating requirement. Weston sits in Broward County’s High Velocity Hurricane Zone. If your bay or bow faces an unobstructed exposure, impact-rated glazing is the compliant path. ECO Window Systems produces impact bow configurations we specify regularly in Weston projects where the aesthetic matters as much as the performance rating.
- Roofline conditions above the projection. Some Weston homes – particularly those built between 1988 and 1998 in Bonaventure and Weston Hills – have soffit configurations that complicate the head flashing detail on a bay projection. If the soffit has to be cut back and re-trimmed, that adds labor. We identify this in the measured survey, not after demo.
- Interior finish work. Bay and bow windows typically require a window seat, knee wall, and interior casing that doesn’t come with the window unit itself. We can scope this as part of the same project or leave it for a separate contractor – your preference is documented in the written scope.
- Lead time on custom-width units. Standard bay units ship in 3 to 5 weeks from our manufacturer lines. Custom-width or non-standard projection depths on bow windows can run 6 to 10 weeks. This affects scheduling, not pricing – but it affects your timeline, so we state it plainly.
The written price you receive from Sightline before any work begins is the price on the final invoice. If the scope changes during demo – say we find rot that wasn’t visible at survey – we stop, document the change in writing, and you approve a revised number before we continue. That’s Haven Clause 5.
Call (754) 812-9260 to schedule your measured survey and written estimate. There’s no charge for the estimate, and you keep the written scope whether you proceed with us or not.

FAQs – Bay & Bow Windows in Weston, FL
How much does a bay or bow window cost in Weston, FL?
A bay window replacement in Weston typically costs $2,800 to $5,500 installed, depending on the opening size and whether framing repair is needed. A bow window (four to six lites) runs $4,200 to $6,500 for a like-for-like replacement, and a new opening cut into an existing wall can reach $7,500 or more. These figures reflect Weston-market pricing and include labor, permit, and standard trim – the written estimate you receive from Sightline will break out every line before a tool is lifted. Call (754) 812-9260 for a no-charge written estimate.
Do bay and bow windows in Weston need to be impact-rated?
Yes, in most cases. Weston is within Broward County’s High Velocity Hurricane Zone, and any window in an exposed opening is required to meet Miami-Dade Notice of Acceptance (NOA) wind-load standards, either through impact-rated glazing or a compliant shutter system. Older bay and bow units – particularly those installed before 2002 – rarely carry current NOA approval. Sightline documents the product approval number for every unit we specify, and that number appears in your written scope before any work starts.
How long does a bay or bow window installation take in Weston?
The physical installation of a bay or bow window replacement in Weston typically takes one to two days once materials are on site. New opening projects – where wall framing, a structural header, and exterior trim work are required – generally run two to three days. Lead time on the window unit itself is the longer variable: standard units from lines like CWS or ES Windows typically ship in three to five weeks; custom widths or bow configurations can run six to ten weeks. We state the lead time in the written scope so the schedule is clear before you sign.
What’s the difference between a bay window and a bow window?
A bay window projects from the wall as a three-section unit: a fixed or operable center lite flanked by two angled side units, typically set at 30 or 45 degrees. The result is an angular projection with a defined interior ledge. A bow window uses four to six lites of equal width arranged in a gentle curve, producing a rounder, more gradual projection. Bay windows are more common in Weston’s single-story homes where the projection depth needs to be limited; Horizontal Roller Windows and bow windows are more often specified in larger rooms where the curved line or wider opening is the design priority. Both require the same impact-rating compliance and framing considerations in Weston.
Can Sightline give me a second opinion on a bay or bow window quote I already have?
Yes. Sightline offers a free second opinion on any written estimate from another contractor. Bring us the quote – or email it – and we’ll review the product specification, the NOA documentation, the framing scope, and the pricing line by line at no charge. If the quote is solid, we’ll tell you. If there are gaps – missing permit costs, unspecified glazing ratings, or framing assumptions that don’t match what we’d expect to find in a Weston home of that age – we’ll document them in writing so you can ask the right questions before signing anything. Call (754) 812-9260 to set that up.
