AfterGarden Windows in North Palm Beach, FL
A garden window projects outward from the wall plane, typically 12 to 18 inches, creating a glass-enclosed shelf that catches full sun from three sides. In North Palm Beach, where east-facing kitchens catch direct morning light and west-facing rooms run hot by mid-afternoon, the orientation of that projection matters as much as the frame itself. Sightline Windows & Doors has fitted garden windows into North Palm Beach homes since 2012 – more than 18,000 openings completed under the Haven Standard, every one with a written price before a tool was lifted.
If you’re weighing this for a kitchen, a breakfast nook, or a sunlit laundry area, our process starts with a measured survey you keep. That survey becomes the written quote – Haven Clause 1 means those two documents are the same document, so the number we hand you before work starts is the number on the final invoice. Call us at (561) 475-1246 to book a free, no-obligation survey for our Window Installation services, or read on to understand exactly what goes into a garden window installation here.
For context on how a garden window fits within our broader scope of work, see our Window Installation in North Palm Beach page.
When You Need Garden Windows
- Your kitchen sill gets full sun and you want to use it. North Palm Beach kitchens that face the Intracoastal or east toward the Atlantic get strong morning light. A garden window turns that sill into a genuinely useful shelf – herbs, small orchids, seedlings – without sacrificing the ventilation that an ordinary fixed window can’t give you.
- Your existing window unit is fogged, cracked, or the frame is soft to the touch. Older aluminum frames in this climate oxidize and pit; the seal between the frame and the sill plate can wick moisture into the wall cavity. When the frame flexes under hand pressure or the glazing has permanent condensation between panes, replacement is the right call, not recaulking.
- You’re renovating a kitchen and the rough opening is already being touched. If cabinets are coming out and the drywall is open, that’s the lowest-cost window to reach the rough opening. Combining the garden window installation with an adjacent renovation saves labor on both sides.
- Your current window doesn’t meet Florida Building Code Section 1609 impact requirements. Homes in North Palm Beach’s High-Velocity Hurricane Zone that still have single-pane or non-impact units above the base flood elevation may need to bring those openings into compliance during any permitted renovation. A garden window can be specified to meet the impact standard – we’ll confirm what your permit requires before the survey is done.
- The outward projection would add light without altering your elevation approval. In North Palm Beach, additions that change a home’s footprint require separate permitting. A garden window is not a structural addition, but it does extend the plane of the building; we pull the relevant permit and document it so there’s no ambiguity if you sell or refinance.
- You want cross-ventilation that a picture window can’t provide. Most garden window units include operable side vents – casement-style panels on the left and right of the fixed center pane. In a kitchen, that ventilation path matters more than most homeowners expect until they’re cooking without it.
Our Garden Windows Process
- Measured survey and written scope. Before we discuss product or price, one of our background-checked, uniformed technicians comes to your home and measures the rough opening, checks the structural header above it, reads the existing frame depth, and documents the exterior wall thickness. In North Palm Beach, that wall thickness varies considerably between CBS (concrete block and stucco) construction, which is common in the older sections near Prosperity Farms Road, and frame construction more typical in the newer builds closer to PGA Boulevard. The frame type changes which flashing approach we use. You keep a copy of that survey document.
- Product specification and written price. Once we have the opening dimensions and wall type on paper, we specify the unit by what the opening requires – projection depth, glazing type (tempered is code-required on operable units in this application), low-E coating, U-factor, and SHGC rating. Garden windows in a west-facing North Palm Beach kitchen benefit from a lower SHGC (solar heat gain coefficient) to limit afternoon heat load. We’ll show you the spec sheet and the written price together. That price does not change when the truck arrives.
- Permit submission. We file the permit with Palm Beach County or with North Palm Beach’s Building Department, depending on the scope. We don’t ask you to track this; we handle it and notify you when the permit is issued. This step typically adds five to ten business days before installation can begin, though timelines vary with the county’s current queue.
- Removal and rough opening preparation. On installation day, we remove the existing window unit and inspect the rough opening, sill plate, and header. Any rot, deteriorated flashing, or compromised sill plate is documented with photographs before we proceed – those photos are part of the job record you receive. If we find damage that changes the scope, we stop, show you the photos, and give you a revised written price before any additional work begins. No surprises is Haven Clause 5 (No Surprises), written into every job.
- Installation and sealing. The garden window unit is set, shimmed, and anchored to the rough framing according to the manufacturer’s installation instructions and Florida Product Approval. We flash the exterior sill and head with self-adhering membrane before the exterior trim or stucco return goes back, which is the step that determines whether the unit stays watertight in a Palm Beach County squall. Interior trim and interior sill finishing are included in the written scope.
- Inspection, photo documentation, and closeout. After installation, we schedule the required inspection, stay through it, and document the inspector’s sign-off. The completed job record includes the pre-installation photos, the installation photos, the inspection sign-off, and the product documentation. That file goes to you when we leave. The 365-Day Done Right Promise is printed on the job record: if it’s not done right, we make it right.

AfterGarden Windows Pricing in North Palm Beach
Garden window installation in North Palm Beach runs $1,100 to $3,400 per unit installed, including labor, permit, and standard interior trim. The range is wide because the variables here are real: opening size, wall construction type, glazing specification, and whether the existing rough opening needs repair before the new unit can be set.
| Scope | Typical Installed Price Range |
|---|---|
| Standard 36″ x 24″ replacement, CBS wall, no rough opening repair | $1,100 – $1,600 |
| 36″ x 36″ unit, frame construction, low-E / low-SHGC glazing | $1,500 – $2,200 |
| Larger unit (48″+ wide), complex wall, rough opening repair included | $2,200 – $3,400 |
What moves the price
- Opening size. Garden windows are priced by the unit, and unit cost scales with projection depth and width. A 30-inch-wide unit with a 12-inch projection costs less than a 48-inch unit with an 18-inch projection – both in product cost and in the labor to set and flash it.
- Glazing specification. Standard tempered glass with a basic low-E coating sits at the lower end. Impact-rated glazing with a documented SHGC below 0.25 costs more, but in a south- or west-facing opening here, it earns back in cooling load reduction. CWS and ES Windows both produce garden window units with Florida Product Approval and documented energy ratings; we’ll show you the spec sheets side by side.
- Wall type and flashing complexity. CBS construction requires a different flashing sequence than frame construction. Stucco returns that need to be cut back, removed, and repaired after installation add labor. We document this in the measured survey so it’s in the written price before work starts, not discovered on installation day.
- Rough opening condition. Sill plates that have held moisture for years – common in CBS homes built before 1990 in the older parts of North Palm Beach – sometimes require sister framing or sill plate replacement before a new unit can be properly anchored. We photograph whatever we find and price it in writing before touching it.
- Permit fees. Palm Beach County permit fees vary by valuation. We include an estimated permit fee in the written price and reconcile any difference after permit issuance – it’s disclosed, not buried.

Garden Window Product Lines We Work With
We don’t stock product and sell from what’s available. We specify from eight manufacturer lines – CWS, ES Windows, ECO Window Systems, Mr-Glass among them – including options for Horizontal Roller Windows and other styles, based on what the opening and the homeowner’s performance targets actually require.
For a garden window in North Palm Beach, the relevant criteria are Florida Product Approval (mandatory for any permitted window installation in the state), impact rating if the opening is in a required protection zone, and SHGC. ECO Window Systems produces units with documented low-SHGC glazing that hold up in west-facing applications where afternoon solar gain is a real factor. CWS makes garden window units with clean aluminum profiles, as well as Picture & Fixed Windows, that fit well into the CBS construction profile of older North Palm Beach homes without requiring a larger rough opening. We’ll show you the relevant spec sheets and let the numbers make the case.
FAQs – Garden Windows
How much does a garden window installation cost in North Palm Beach?
Garden window installation in North Palm Beach typically runs $1,100 to $3,400 installed, depending on the unit size, wall construction type, glazing specification, and whether the rough opening needs repair. A standard 36-inch replacement in a CBS wall with no structural repair lands between $1,100 and $1,600 installed with permit. Call (561) 475-1246 for a free measured survey and written price – that written number is what you’ll see on the final invoice.
Do garden windows meet Florida’s impact requirements?
Garden windows can be specified with impact-rated glazing that carries Florida Product Approval and meets Florida Building Code Section 1609. Not all garden window units on the market carry this rating, so the specification step matters. During our measured survey, we confirm whether your opening falls within a zone that requires impact-rated glazing and specify accordingly. If the opening doesn’t require impact rating, we’ll document that too so you have it in writing.
How long does a garden window installation take in North Palm Beach?
The installation itself – removal, rough opening prep, setting the unit, flashing, and interior trim – typically runs four to six hours for a single opening with no structural surprises. Permit processing with Palm Beach County or North Palm Beach’s Building Department adds roughly five to ten business days before installation can begin, sometimes longer depending on the county’s current queue. We handle permit submission and track the timeline so you don’t have to.
Will a garden window affect my home insurance in North Palm Beach?
A permitted garden window installation with a documented Florida Product Approval can support a wind mitigation credit with your insurer, particularly if the previous unit was non-impact and the replacement is impact-rated. We document the product approval number and the inspection sign-off in your job record. We’re not insurance agents and won’t make specific premium predictions, but we give you the paperwork your insurer needs to make the determination. Bring your current policy’s wind mitigation requirements to the survey and we’ll confirm what the installation will and won’t satisfy.
Can a garden window be installed in a concrete block wall?
Yes – CBS (concrete block and stucco) construction is the most common wall type in older North Palm Beach homes and it’s what we work in regularly, whether for garden windows or Single & Double Hung Windows. The flashing sequence is different from frame construction: the stucco return has to be cut back, the anchor method at the jambs changes, and the exterior sill flashing is applied before any stucco repair. We document the wall type in the measured survey and account for it in the written price, so there’s no adjustment at installation.
