How Custom Windows Are Made: The Riviera Beach Reality

Custom windows are built to order from precise measurements, with each unit fabricated around the exact opening size, glass package, frame material, and impact rating the job demands. A true custom window starts as a set of dimensions on a work order and ends as a finished, factory-tested assembly that fits one specific opening in one specific wall. In Riviera Beach, that process nearly always includes Florida Product Approval documentation and impact-rated glass, because the coastal wind-load requirements here do not bend. If you are weighing custom windows for a home here, call TruePane Windows & Doors at (786) 829-6722 and we will walk you through the entire build path before you spend a dollar.

Dale Kessler, owner of TruePane Windows & Doors, sums up the whole craft in one rule we keep in the shop: “If it is not right on paper, it will not be right on the wall.” A custom window is not a stock unit pulled from a warehouse shelf and shimmed into place. It is a sequence of decisions, each one made before the first frame piece is cut.

What “Custom” Actually Means

Most people assume custom means unusual shapes, like arches, circles, or floor-to-ceiling trapezoids. Those exist, and we build them. But in our Riviera Beach work, custom more often means a stock-window opening that no longer matches any stock-window size, or a frame material and glass package combination no standard line carries. Houses on the mainland, mostly concrete block built in the 1950s through 1970s, sit with original single-pane jalousie or horizontal-slider openings. Those dimensions were set before modern impact code, before insulated glass, before anyone thought about a Category 5 wind load. The window that fits that hole today does not come from a catalog. It comes from a fabrication order.

Custom fabrication follows a six-stage path. Each stage matters, and skipping any one of them is how a window ends up out of true.

Stage One: Measure the Opening, Then Measure It Again

Every custom window begins with dimensions taken from three points: top, middle, and bottom for width, and left, center, and right for height. Concrete block openings shift over decades. A wall that reads 48 inches at the header can read 48 and 3/8 at the sill. We record the smallest workable dimension and build to that, then flash and seal the gap.

On Singer Island, where TruePane does a steady share of high-rise replacement work, measurement carries extra weight. Original 1970s and 1980s sliding glass doors in oceanfront condos arrive at replacement with aluminum tracks corroded so badly from decades of salt spray that the panels have become fixed walls. You cannot fudge a measurement on a 20-story tower where the engineer-of-record signs off on every opening. We measure with a folding rule, not a tape, because Dale picked up the habit from his father’s finish carpentry days and never saw a reason to change it.

Stage Two: Choose the Frame and Glass Package

The frame material drives the glass weight the window can carry. In Riviera Beach, the practical choices are:

• Aluminum: Strong and well suited to impact glazing, but vulnerable to salt-air pitting unless finished with a marine-grade coating. On Singer Island, we specify this finish every time because standard anodizing fails within a few years of direct ocean exposure.
• Vinyl: Good thermal performance and immune to salt corrosion, which makes it a solid mainland choice. Taller impact units need steel reinforcement inside the vinyl extrusion.
• Wood or wood-clad: Beautiful but rare in direct coastal exposure. We steer most beachfront homeowners toward aluminum or vinyl unless the condo association’s aesthetic guidelines require wood.

Glass packages for custom windows in this area almost always include laminated impact glass rather than a separate hurricane shutter. The laminate layer is what holds the pane together when debris hits. Both PGT and CGI build their custom impact lines to Florida Product Approval standards, and TruePane is an authorized installer for both, along with ES Windows for high-end architectural work.

Stage Three: Fabrication at the Manufacturer

Once we place the order, the manufacturer cuts the frame extrusions to the submitted dimensions, welds or mechanically joins the corners, and installs the glass into the sash. For impact windows, the laminated glass gets cut and sealed under factory conditions, not on your driveway. The finished unit then goes through testing to confirm it meets the design pressure rating stamped on the Florida Product Approval document.

Here is where the difference between a real custom window and a mislabeled stock unit shows up. A stock window manufactured in bulk does not get tested against your specific opening. A custom unit does, because the fabricator knows the exact dimensions, glass recipe, and wind-load rating before the line starts. When we order a custom window for a Riviera Beach home, the paperwork names the address, the opening, and the product approval number. If the paper is not right, the window is not right.

Stage Four: Shipping and Handling for Coastal Conditions

Custom windows ship on edge, wrapped, and labeled per opening. For Singer Island projects, we coordinate with the condo association’s loading dock and freight elevator schedule. A 6-foot-by-8-foot impact slider for a 12th-floor unit does not ride up in the passenger elevator. This is one reason high-rise custom work costs more and takes longer than mainland single-family installs, and why we quote it separately side by side on paper so the homeowner sees exactly what they are buying.

Stage Five: The Install That Makes or Breaks the Window

A perfectly fabricated window installed out of level will bind, leak, and fail its own warranty. We set every unit with shims at the manufacturer’s specified bearing points, check level and plumb with a 6-foot level, and fasten through the frame into the concrete block or buck framing at the spacing the approval document requires. Then comes the flashing: backer rod, sealant, and a sill pan where the opening calls for it.

In the oldest Singer Island units, we also have to account for asbestos-containing glazing compounds from the original 1960s and 1970s installs. That material stays in place unless the opening is being fully demolished, and when it must come out, it comes out under proper containment procedures, not with a crowbar and a Shop-Vac. This is part of the job that cheap bids quietly skip.

Stage Six: Warranty Registration Before the Truck Leaves

Every TruePane custom window job ends with The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. Most window warranties have two layers: the glass seal warranty and the frame/hardware warranty. Homeowners in Riviera Beach lose both when a contractor forgets to file the registration or never tells the homeowner the durations. We state them on the invoice and register them that day. Then the Done Right Promise covers the workmanship: if the window is not right, we make it right, no paperwork fights and no arguing.

What Custom Windows Cost in Riviera Beach

Pricing depends on frame material, glass package, impact rating, and whether the job is mainland single-family or high-rise condo. The table below reflects typical ranges we quote for custom work in this area.

These are working ranges, not quotes. A field measurement changes everything, and that is the point of a custom window. We encourage homeowners to get a side-by-side quote from at least two manufacturers, because comparing an Andersen to a CGI on paper is the only honest way to see what you are paying for.

Common Local Scenarios We See

Riviera Beach homeowners do not call us about custom windows in the abstract. They call with a specific problem. Here are the ones that repeat:

• The Singer Island slider that will not slide. Salt has eaten the aluminum track and the rollers are seized. The glass is fine. The frame is gone. This is a full custom replacement, because the opening is non-standard and the association requires FPA-rated product with engineer sign-off.
• The mainland jalousie window in a 1962 CBS house. The homeowner wants it gone because it leaks air and makes the AC bill climb every July. The opening is 72 inches wide, which no stock window matches. Custom vinyl impact unit, built to fill the opening and rated for the coastal wind zone.
• The condo tower doing mandatory recertification. SB 4-D milestone inspections have pushed building-wide replacement programs across Singer Island. The association needs commercial-grade impact glazing, specialized high-rise rigging, and a contractor who can work around residents still living in the building. We have done enough of these to know the rhythm.

Dale grew up in the Blue Heron neighborhood, spent enough teenage weekends watching the drawbridge go up and down to learn patience, and learned the glazing trade at Palm Beach State College, where a sheet-metal instructor told him a bad seal is just a slow leak waiting for the right storm. That advice stuck, and it is why we treat window work here as a craft commitment, not a transaction.
