AfterCustom Impact Windows in Palm Beach, FL
Custom impact windows in Palm Beach are hurricane-rated, heavy-duty units built to fit openings that standard off-the-shelf sizes simply don’t cover – arched transoms, trapezoids, oversized picture windows, and the tall coastal casements common throughout the island’s historic estates and newer waterfront construction. A quality custom impact window handles Category 5 wind loads and flying debris while staying true to the architectural character of the home. At Winslow Windows & Doors, we’ve been measuring, ordering, and installing exactly these kinds of units since 2011, and Ed Winslow personally stands behind every one.
If you’re ready to talk dimensions and budgets, call us at (561) 831-7863 – a live person picks up, any hour of the day or night, no voicemail. Or read on to understand what goes into a custom impact window job in Palm Beach before you commit to anything.
This page is part of our broader work with Custom & Geometric Windows in Palm Beach – custom impact units represent the intersection of specialty shapes and storm protection, which is why they deserve their own detailed look.
When You Need Custom Impact Windows
Not every Palm Beach home needs custom sizing, but a surprising number do. Here are the situations we see most often:
- Existing windows fail the Miami-Dade Notice of Acceptance (NOA) test. Palm Beach County enforces strict impact ratings, and older aluminum single-pane windows installed before 2002 almost never meet current code. If your insurer has flagged your windows or your contractor mentioned NOA compliance, you likely need full replacement – and if the openings are non-standard, custom impact units are the only path forward.
- You have arched, round, or angled openings that standard sizes don’t fit. Many homes in the El Cid and South End neighborhoods of Palm Beach feature Mediterranean Revival architecture with arched window bays. Standard rectangular impact windows leave those openings partially blocked or require unsightly filler frames. A custom-shaped impact unit fills the opening cleanly and maintains the home’s original profile.
- Your current windows rattle, leak air, or admit water during heavy rain. Palm Beach sits directly on a barrier island, and the salt-laden southeast wind off the Atlantic degrades seals and frames faster here than it would ten miles inland. If you’re hearing wind whistle through closed windows during a storm, the weather seal has failed – and with a custom window, the only real fix is a replacement unit made to the exact dimensions of that opening.
- You’re undertaking a renovation or addition that creates new or altered openings. Additions to historic Palm Beach properties, roofline changes, or second-story additions frequently produce opening dimensions that don’t correspond to any catalog size. Building these out with custom impact windows from the start is far cheaper than trying to adapt standard units with filler frames later.
- Your insurance carrier is requiring impact-rated glazing for renewal. Several major Florida carriers have tightened their underwriting in Palm Beach County since 2023, requiring documented impact-rated windows as a condition of homeowner policy renewal. Custom impact windows with the correct NOA or Florida Product Approval number satisfy that requirement precisely.
- You’re combining storm protection with a design upgrade. Homeowners on North Lake Way and along South Ocean Boulevard frequently ask us to replace functional but plain aluminum windows with custom impact units in bronze or black finishes, with divided-light grids that match the original muntin patterns. The storm protection is the compliance requirement; the custom order is what preserves the look of the home.
Our Custom Impact Windows Process
A custom impact window project has more moving parts than a standard replacement, mostly because every unit is made to order. Here’s how we handle it:
- Detailed field measurement and opening assessment. Ed or one of our background-checked technicians visits the property and takes three-point measurements of every opening – width, height, and diagonal – at multiple locations to account for out-of-square frames. We check the sill condition, note the wall depth, identify the rough opening material (concrete block, CBS, or wood frame), and photograph everything. This step is not something we delegate or rush; a wrong measurement on a custom order means a unit that can’t be installed, and the factory doesn’t issue credits for field errors.
- Product selection and specification. We match the opening dimensions, the performance requirements (design pressure rating, impact category, energy performance), and the design goals to the right product from our authorized lineup. For Palm Beach, we frequently specify PGT or CGI custom series impact windows – both carry the Florida Product Approval numbers that satisfy Palm Beach County’s permitting office and most insurance underwriters. We walk you through frame color, glass tint, low-e coating options, and grid patterns before anything is ordered. Upfront pricing – no surprises on the invoice.
- Permit application and approval. Custom impact windows in Palm Beach require a building permit, and the Florida Product Approval number for each unit must be submitted with the permit application. We handle the paperwork, submit the drawings, and coordinate with the Palm Beach Building Division. Permit lead times in Palm Beach can run two to four weeks depending on the division’s workload; we build that into the project schedule so you’re not caught off guard.
- Factory order and lead-time management. Custom units are not stock items. Depending on the manufacturer and the complexity of the shapes involved, lead times typically run four to ten weeks from order confirmation. We give you a realistic timeline at the point of order – not the optimistic one designed to get you to sign – and we follow up with the factory on your behalf so you’re not left wondering.
- Installation day – prep, removal, and set. Our uniformed crew removes the existing windows carefully, protects interior finishes, and sets each new custom impact unit using the manufacturer’s approved installation method for the substrate type. Concrete block installations in Palm Beach require specific anchor patterns and sealant types that differ from wood-frame installations; we’ve done enough of both in this area to know exactly which detail applies where. High-tension components in window systems can store significant energy – we follow all manufacturer safety protocols to the letter, and we don’t improvise shortcuts on that front.
- Inspection, seal, and final walkthrough. After installation, the job is inspected by the Palm Beach Building Division. Once we pass inspection, we apply the final exterior sealant, clean the glass, remove all debris, and walk you through the operation of every unit – tilt-wash function, locks, and any egress requirements for bedroom windows. The job isn’t closed until you’re satisfied. That’s the 36500-Day Done Right Promise, and Ed’s name is on every job we do.
Custom Impact Windows Pricing in Palm Beach
Custom impact windows in Palm Beach cost more than standard replacement impact windows because every unit is manufactured to your exact dimensions. The price range below reflects our real-world project data from Palm Beach and the surrounding barrier island communities – not a national average.
| Window Type | Approximate Installed Cost Per Unit |
|---|---|
| Custom rectangular impact (non-standard size, single unit) | $900 – $1,800 |
| Custom arched or radius impact window | $1,400 – $2,800 |
| Custom trapezoid or triangle impact unit | $1,200 – $2,400 |
| Large custom picture/fixed impact window (over 50 sq ft of glass) | $2,200 – $5,000+ |
| Custom impact casement or awning unit | $1,100 – $2,200 |
| Permit fees (Palm Beach Building Division) | $150 – $600 depending on project scope |
Several factors move the final number up or down on any given job:
- Glass package. Standard clear laminated impact glass is the baseline. Low-e coatings, high-solar-gain or low-solar-gain formulas, tinted interlayers, and decorative glass options each add to the unit cost. In Palm Beach, where east-facing windows take direct Atlantic sun from sunrise through early afternoon, a quality low-e coating pays for itself in energy savings faster than most homeowners expect.
- Frame material and finish. Standard white vinyl is the most affordable. Extruded aluminum in bronze, dark bronze, or black – common on Palm Beach estates – carries a premium but holds up to the salt-air environment better over time. Anodized aluminum frames from CGI or PGT in custom colors can add 15-25% to the unit cost.
- Opening condition. If the existing rough opening has water damage, deteriorated sill plates, or corroded anchor points – all common in Palm Beach homes within two blocks of the ocean – that repair work is priced separately and honestly before the installation begins, not discovered on invoice day.
- Number of units. Multi-unit projects typically allow for some efficiency in mobilization and permit costs, which we pass along to you. A whole-home custom impact window project is not the same per-unit cost as a single specialty window.
- Senior and veteran discount. We offer a permanent 10% discount for seniors and veterans – not a promotional period, not a limited-time deal. If you qualify, we apply it automatically.
Estimates are free, and we don’t charge a trip fee inside Palm Beach County. Call (561) 831-7863 to schedule yours – someone answers, every time.
FAQs – Custom Impact Windows in Palm Beach
Do custom impact windows in Palm Beach require a permit?
Yes, every impact window replacement in Palm Beach requires a building permit, and custom units require the Florida Product Approval number for each specific window to be submitted with the application. The Palm Beach Building Division enforces this consistently, and any contractor who tells you a permit isn’t necessary is either misinformed or cutting corners that will surface during a future sale inspection. We handle the permit application as part of every project – it’s not an add-on service, and we don’t charge a separate administrative fee for it. Call (561) 831-7863 if you have questions about what your specific project requires.
How much do custom impact windows cost in Palm Beach compared to standard impact windows?
Custom impact windows in Palm Beach typically run 25-60% more per unit than catalog-size impact windows of the same glass area, because each unit is made to order at the factory rather than pulled from inventory. For a single custom arched or geometric unit, expect $1,400 to $2,800 installed. For non-standard rectangular units that are simply larger or smaller than standard sizes, the premium is usually closer to 20-35%. The permit costs are the same either way – they’re based on project value, not whether the windows are custom or stock. For a free, no-obligation estimate on your specific openings, call us at (561) 831-7863.
How long does a custom impact window order take in Palm Beach?
From the date you approve the specification and sign the order, factory lead times for custom impact windows from manufacturers like PGT or CGI typically run four to ten weeks, depending on shape complexity and current factory capacity. Add two to four weeks for Palm Beach Building Division permit review on the front end, and you’re generally looking at a six to fourteen week total timeline from signed contract to installation day. We give you a realistic schedule at the time of order and communicate any changes proactively. No surprises is the standard we hold ourselves to.
Can Winslow Windows & Doors match the original window style on a historic Palm Beach home?
In most cases, yes. Palm Beach has a high concentration of Mediterranean Revival, Colonial Revival, and Bermuda-style homes built between the 1920s and 1960s, and matching the original divided-light patterns, frame profiles, and proportions matters both aesthetically and, in some cases, for historic preservation board approval. We work from photos of the existing windows, original architectural drawings when available, and the specifications of the PGT and CGI custom series, which offer a range of simulated divided-light grid options and frame profiles that replicate historic details while meeting current Miami-Dade impact standards. If your property falls under Palm Beach’s Landmarks Preservation ordinance, we recommend confirming the approved specifications with the town’s Historic Preservation Planner before we submit the permit – we can help you prepare that documentation. Call (561) 831-7863 to talk through the specifics of your home.
Why Palm Beach Homeowners Choose Winslow Windows & Doors
There’s no shortage of window contractors in South Florida, and Palm Beach homeowners get solicited regularly. Here’s what makes the difference with us, stated plainly.
Ed Winslow started this company in 2011 and it’s still locally owned, still owner-operated, and still based here in South Florida – not a franchise that flies a local-sounding name over a national call center. When you call (561) 831-7863, you reach a live person who knows the Palm Beach Building Division’s current permit turnaround times, knows the difference between a CBS wall installation and a wood-frame installation, and can tell you which PGT or CGI product line carries the right Florida Product Approval for your specific opening. That’s not something you get from a national chain.
Every technician we send to your home is background-checked and arrives in uniform – you know exactly who is at your door before the truck pulls up. Upfront pricing means the estimate you approve is the invoice you receive, with the only additions being scope changes you authorize in writing. And the 36500-Day Done Right Promise means that if something isn’t right after we leave, we come back and make it right. Not because a warranty document says we have to – because Ed’s name is on the door.
We’re also authorized installers for eight premium brands – including PGT and CGI, the two manufacturers whose custom impact series we recommend most often for Palm Beach’s barrier-island conditions. Authorization matters because it means we receive current installation training directly from the factory, and it means your warranty is valid – factory warranties on unauthorized installations are frequently voided.
If you’ve gotten a written estimate from another contractor and want a second opinion, we provide that free – no obligation, no pressure. We’ve found that homeowners who do this almost always discover something in the first estimate that needed clarifying, whether it’s a missing permit line item, an unlisted frame color upcharge, or a product that doesn’t carry the correct Florida Product Approval for the county. Call us and we’ll go through it with you.
