AfterBay & Bow Windows in Sunrise, FL
Bay and bow windows in Sunrise, FL typically run between $2,800 and $9,500 installed, depending on the number of window units, frame material, and whether the glass needs to be impact-rated for South Florida’s wind-load requirements. Most projects in Sunrise are completed within one to two days once the custom units arrive from the manufacturer. Sightline Windows & Doors Sunrise writes the price before a single measurement is recorded on your wall – that figure is the one on the invoice.
If you’re considering a bay or bow addition – or replacing an older projection window that’s sweating condensation or leaking around the roof cap – this page covers how these windows are built, what the installation involves in a Broward County home, and what you’ll pay. For a broader look at what we do, our Window Installation in Sunrise page covers the full scope of services.

What Makes Bay and Bow Windows Different
Both window types project outward from the exterior wall, adding interior floor space and exterior visual depth. The difference comes down to geometry. A bay window uses three units: one fixed center panel flanked by two operable casement windows or double-hungs set at 30-degree or 45-degree angles. A bow window uses four, five, or six units arranged in a gentle curve, each unit typically set at 10-degree increments to produce that rounded profile you see on craftsman and transitional-style homes throughout Sunrise neighborhoods like Welleby and Sunset Strip.
That outward projection creates a structural situation that doesn’t exist with a standard window installation. The framing above the opening requires a header that spans the full width of the rough opening. The roof cap or copper flashing above the projection must be watertight – in a South Florida climate that drops several inches of rain in a single afternoon during hurricane season, a poorly flashed bay roof is one of the faster ways to develop interior water damage. The seat board below the window and the knee wall below the seat board have to be properly insulated and vapor-sealed as well, because unconditioned cavities in Broward County’s heat and humidity grow mold quickly.
We also see bay windows specified in Sunrise homes where homeowners want impact-rated glazing throughout. Impact-rated glass in a multi-unit bay or bow assembly involves laminated glass in every lite, and the framing and mullion design has to meet the same wind-load standards as any other opening in a Miami-Dade or Broward-compliant installation. Not every installer who handles standard window replacements has experience specifying impact-rated bay and bow assemblies – the load paths are different when the window projects beyond the wall plane.
When You Need Bay or Bow Windows
- You’re replacing an existing projection window that leaks. Older bay windows installed in the 1990s and early 2000s – common in Sunrise developments like Springtree and New River Estates – frequently develop flashing failures at the roof cap junction. If you see water staining on the ceiling directly above the seat board after heavy rain, the roof cap is the first place to check.
- Your current bay window fogs between the panes. Fogging means the insulated glass unit (IGU) seal has failed. In Sunrise’s high-humidity environment, seal failure tends to accelerate once it starts – you’ll typically see it first in the fixed center panel, which gets the most direct afternoon sun from the west-facing elevations common in the Welleby area.
- You want to add square footage without a structural addition. A standard bay window projecting 18 to 24 inches adds a meaningful reading nook or breakfast area without a permit-intensive room addition. In Broward County, projection windows still require a building permit, but the scope is far simpler than an addition.
- Your home needs impact-rated openings and the existing bay doesn’t qualify. If you’ve upgraded the rest of your windows to impact-rated glass, an older single-pane or standard insulated bay window is a code and insurance gap. Several Sunrise insurers now request documentation that all openings meet current wind-load specs – a written product spec sheet from the manufacturer is the documentation that travels with our invoices.
- You’re building new or renovating and want a bow window on a curved facade. Bow windows on five or six units work well on the curved front elevations found in some of the newer construction along NW 136th Avenue in Sunrise. The gentle radius integrates cleanly with stucco cladding when the flashing and exterior trim are properly detailed.
- The seat board or knee wall below an existing bay has soft spots or visible rot. Wood deterioration in the sub-seat framing is a sign the vapor barrier below failed years ago. Replacing only the glass units without addressing the framing leaves the new window sitting on compromised structure.

AfterOur Bay and Bow Windows Process
- Measured Survey – the document you keep. Sonia Raman or one of our background-checked, uniformed technicians visits the opening and records the rough opening width, height, projection depth, head height clearance, roof cap pitch, and knee wall depth. These numbers go on a survey form you receive a copy of before we leave. Haven Clause 1 – Have It in Writing – means the written price cannot differ from what that survey document shows.
- Product Specification. Based on the measured survey, we specify the unit count, glass package (impact-rated laminated, standard insulated, or low-E coated for SHGC and U-factor targets), frame material, and interior finish. For homes in Sunrise that need impact-rated glass, we typically work from the ES Windows or ECO Window Systems lines, both of which produce impact-rated bay configurations that meet Broward County’s current wind-load requirements. The written quote names the product line, series, and glass package explicitly.
- Permit Pulling. Broward County requires a building permit for bay and bow window installations because they involve structural header work and an exterior wall opening. We handle the permit application and coordinate with the county inspector’s schedule. The permit number goes on your job file.
- Structural Header and Rough Opening Preparation. On installation day, we expose the existing rough opening, verify the header is sized for the full projection span, and frame the knee wall and seat board cavity. Any deteriorated framing members are replaced and documented in the photo record before the new window units arrive on-site. You see what we found before we close it up.
- Window Installation and Flashing. The bay or bow assembly is set into the opening, leveled, shimmed, and anchored to the framing. The roof cap flashing – typically aluminum or copper – is lapped and sealed to the exterior wall cladding. In Sunrise, we apply a continuous bead of impact-rated sealant at the perimeter of the flashing because the afternoon convective storms here drive water horizontally in a way that inland installations don’t encounter at the same frequency.
- Inspection, Photo Record, and 365-Day Done Right Review. After the county inspector signs off, our technician walks through the completed installation with you, demonstrates the operable units, and records the final photo documentation. Every job leaves a documented photo record – Haven Clause 4, Evidence on Every Job. The 365-Day Done Right Promise is written into your job file: if it’s not done right, we make it right, without a service call charge.
Bay and Bow Windows Pricing in Sunrise
Bay and bow window pricing in Sunrise covers a wide range because the variables are real: number of units, glass package, frame material, whether structural framing needs repair, and permit fees. The table below reflects what we see in practice across Broward County homes. These are installed ranges – product, labor, permit, and standard flashing included.
| Configuration | Installed Price Range | Notes |
|---|---|---|
| 3-unit bay, standard insulated glass, vinyl frame | $2,800 – $4,200 | Most common replacement in Sunrise tract homes; no impact rating |
| 3-unit bay, impact-rated laminated glass, vinyl frame | $4,500 – $6,500 | Meets Broward County wind-load; insurance documentation included |
| 4-unit bow, standard insulated glass, vinyl frame | $3,800 – $5,500 | Curved profile; more seat board framing labor |
| 5-unit bow, impact-rated laminated glass, aluminum or composite frame | $6,500 – $9,500 | Larger openings; aluminum frame adds longevity in salt-air proximity |
| Structural framing repair (if needed) | $400 – $1,200 additional | Documented in survey and written price before work starts |
| Broward County permit fee | $150 – $350 | County-set; included in written quote |
What drives cost up: a larger projection depth (24 inches vs. 12 inches requires more knee wall framing and a longer seat board), choosing aluminum or composite frames over vinyl, adding a decorative hip roof cap with copper flashing, and any structural header work the survey uncovers. What keeps cost down: a straightforward opening with an existing header that’s already properly sized, a vinyl frame in a standard white or bronze finish, and a standard insulated glass package where impact rating isn’t required.
If you’ve already received a written estimate from another installer, our Free Second Opinion on Any Written Estimate means we’ll review it at no charge – and tell you plainly whether the product specification and labor scope match what your opening actually needs.
Call (754) 254-5294 to schedule the measured survey. The written price comes from that survey document, and the two figures are always the same.
Local Considerations: Bay and Bow Windows in Broward County’s Climate
Sunrise sits roughly ten miles from the Atlantic coast, close enough that aluminum frames in direct exposure can show oxidation within a few years if the anodizing or paint system isn’t specified correctly. When we spec aluminum-framed bay or bow windows for homes in the western Sunrise neighborhoods near the Sawgrass Expressway corridor, we note the distance from salt air in the survey and adjust the frame finish specification accordingly. For homes closer to the Intracoastal, a thermally broken aluminum frame with a high-performance coating is the more durable choice over a 10-year horizon. Garden windows face similar coastal exposure challenges and benefit from the same finish considerations.
Broward County’s building code also requires that any new exterior opening, including a bay or bow window that modifies the structural wall, be permitted and inspected. We’ve seen homeowners in Sunrise discover, during a home sale, that a bay window installed by a previous owner was never permitted. That creates a title and closing problem. Every Sightline installation includes permit coordination as a standard line item – not an add-on – because Haven Clause 2, Arrive on Schedule, includes arriving with the paperwork in order before any work starts.
The afternoon storm pattern in Sunrise also affects how we seal the roof cap flashing. Between June and October, convective storms can push several inches of rainfall in under an hour with wind-driven horizontal rain at the roof-wall junction. A bay roof cap that’s correctly installed and sealed in a drier climate may not perform the same way in this environment. We add a secondary sealant bead at the wall-flashing lap specifically because of what we’ve seen on service calls in Sunrise homes where the original installation didn’t account for that kind of water event.

FAQs – Bay and Bow Windows in Sunrise, FL
How much do bay and bow windows cost in Sunrise?
Installed prices in Sunrise range from $2,800 for a basic three-unit bay with standard insulated glass to $9,500 or more for a five-unit impact-rated bow window with an aluminum or composite frame. Horizontal roller windows in comparable sizes typically fall at the lower end of that range. Permit fees, structural framing repairs, and roof cap flashing upgrades add to that range if the survey identifies them – but they’re named on the written quote before any work starts. Call (754) 254-5294 for a measured survey; the written price comes from that visit.
Do bay and bow windows require a permit in Broward County?
Yes. Any bay or bow window installation in Broward County that involves modifying the structural wall opening requires a building permit and a county inspection. Sightline pulls the permit, coordinates the inspection, and includes the permit fee in the written quote. We’ve seen unpermitted bay windows create real problems for Sunrise homeowners at closing – the permit is not optional, and it’s not an add-on we charge extra to handle.
Can bay and bow windows be impact-rated in Sunrise?
Yes – impact-rated bay and bow configurations are available in both vinyl and aluminum frames from the product lines we work with, including ES Windows and ECO Window Systems. Impact-rated bay units use laminated glass in every lite and a reinforced frame assembly that meets Broward County’s current wind-load requirements. If your insurer has flagged the bay window as a non-impact opening, the written product specification from the manufacturer is the documentation that resolves it.
How long does a bay or bow window installation take in Sunrise?
The installation itself typically takes one full day for a three-unit bay window and one to two days for a larger bow window. Lead time from the measured survey to installation day runs three to six weeks, depending on the manufacturer’s production schedule for custom-sized units. The county inspection is typically scheduled within a few business days of installation completion. We give you the timeline in writing at the time of the quote so there’s no guesswork on scheduling.
Is it cheaper to repair or replace a bay window in Sunrise?
It depends on what’s failing. If only one insulated glass unit has fogged, replacing that single IGU – typically $300 to $600 – makes sense if the frame and flashing are otherwise sound. But if the roof cap is failing, the knee wall framing has deteriorated, or the frame itself has warped or corroded, a full replacement is almost always the lower long-term cost because piecemeal repairs on a structurally compromised bay tend to accumulate quickly. The measured survey tells us which situation you’re in before any money changes hands.
Why Sightline for Bay and Bow Windows in Sunrise
Sightline Windows & Doors has installed more than 18,000 windows and doors since 2012, every one with a written price before work started and a documented photo record when it finished. That’s not a marketing claim – it’s the operating structure under the Haven Standard, which applies to every job Sonia Raman’s team touches in Sunrise and across Broward County.
For bay and bow windows specifically, the Haven Standard matters because these projects involve more moving parts than a flat window replacement: structural framing, roof cap flashing, a building permit, and a custom-manufactured product with a production lead time. Each of those is documented, named in the written quote, and covered by the 365-Day Done Right Promise. If a flashing detail fails during the first year’s rainy season, we come back and fix it – written into the job file, not offered as a courtesy.
