AfterCWS Window Replacement: The Royal Palm Beach Owner’s Guide
We stock and install CWS-compatible replacement windows for homes throughout Royal Palm Beach, with most single-window swaps running $450-$1,100 installed depending on size, glass package, and frame condition. Flange-mounted CWS units in stucco openings run on the low end; mulled or impact-rated assemblies run higher. Most Royal Palm Beach homeowners discover the problem the same way: a window that won’t close square anymore, a crank that spins without moving the sash, or condensation that won’t clear between the panes. By the time you notice it, the seal or hardware has usually been failing for months.
Which CWS Models This Applies To
CWS (Custom Window Systems) built several series over the years that show up regularly in Royal Palm Beach homes: the 4500 and 6500 aluminum single-hung, the 6000 horizontal roller, and the 7900 and 9800 impact-rated lines. The compatibility gotcha owners hit is that CWS changed extrusion profiles between manufacturing runs, so a sash from a 2006 4500 will not always seat in a 2012 4500 frame even though both carry the same series name. We measure the glass size, the frame depth, and the glazing bead profile before we quote anything, and we read the AAMA label on the side jamb to confirm the manufacturing date. For CWS specifically, we lean toward OEM where the window is under warranty or is an impact unit, because the metal gauge and interlock geometry are matched. On older non-impact units out of warranty, a quality aftermarket sash from a Florida supplier often outperforms the original at a lower price. We’ll show you both options side by side on paper before you spend a dollar.
Signs Your CWS Window Replacement Is Failing
- Fog or haze between the panes that never clears. The insulating glass unit (IGU) has lost its seal. In Royal Palm Beach’s humidity, a failed seal draws moisture in and it condenses on the interior glass surface permanently. Once visible fog appears, the argon or krypton fill is gone and the glass’s thermal performance is done.
- The crank handle spins freely or binds. CWS casement and awning operators fail at the gear box first. The plastic internal gears strip under years of direct sun and salt air, and lubricating them only buys a few weeks. The window still holds, but it no longer ventilates.
- The sash drops when you unlock it, or won’t stay open. The spiral or block-and-tackle balances have lost tension. CWS single-hungs built before 2010 used a metal spiral balance that corrodes along Royal Palm Beach’s east-west exposure and suddenly lets go. This turns a functioning window into a pinch hazard.
- Water staining on the interior drywall under the window. The frame’s weep system is blocked or the sealant at the fin has failed. Water is entering the wall cavity, not just the sill. Given Royal Palm Beach’s summer rain patterns (afternoon downpours against west-facing walls), this needs attention before the next hurricane season.
- You can feel air move around the frame with the window closed and locked. The weatherstripping has compressed past recovery or the sash has warped out of plane. Your AC is working harder every month, and your electric bill confirms it.

Every quote includes the new unit, all sealants and flashing materials, removal and disposal of the old window, and labor. Permits are pulled where Royal Palm Beach code requires them, and we handle the inspection scheduling.

The workmanship is covered by our Done Right Promise. If it is not done right, we make it right. No paperwork, no arguing.
DIY or Call Us?
You can safely do the diagnosis. Check whether the window label is still readable on the side jamb, measure the visible glass area, and note whether the frame is aluminum or vinyl. That information helps us quote faster when you call. Replacing the unit yourself is where it goes wrong. CWS flanged windows set into stucco openings require cutting the exterior sealant, removing the existing fin without damaging the waterproof barrier underneath, and re-flashing the opening so water can’t ride the next storm into your wall. Get that wrong and you’ve turned a $600 window replacement into drywall repair, insulation replacement, and possibly mold remediation. Dale Kessler has been setting and sealing windows across Palm Beach County for nearly three decades, and he will tell you plainly: if it is not sealed right, the next storm will tell you. Call (386) 251-6745 and we’ll schedule a measure.
FAQs
A well-installed CWS window in Royal Palm Beach typically lasts 15 to 25 years before the seal, hardware, or frame shows real wear. Salt air from the coast, west-facing afternoon sun, and hurricane-season wind loads compress that lifespan toward the lower end. Windows installed before Florida’s 2002 building code update tend to fail earlier. Call (386) 251-6745 for a condition assessment on your specific windows, free of charge.
In most cases, no. The insulating glass unit can sometimes be replaced without replacing the entire window, but only if the frame and hardware are still sound. With CWS aluminum frames that are 15-plus years old, the frame is usually fatigued enough that a full replacement is the smarter money. We will tell you which route makes sense after seeing the window, and the estimate is free.
A single standard-size CWS window replacement takes most of a day, from old window out to final cleanup. Impact-rated openings and mulled assemblies can run into a second day for proper flashing and inspection. We’ll give you a specific timeline in writing before work begins, and we’ll be there when we say.
We stock the most common CWS hardware and glass sizes on our service trucks, including balances, crank operators, and IGU replacements. For less common series like the 9800 impact line, we order directly from our Florida CWS supplier, and that typically adds 3 to 5 business days. We’re an independent service provider, not affiliated with CWS, but we’ve been sourcing their lines long enough to know what’s available and what’s been discontinued. Call (386) 251-6745 and we’ll check stock while you’re on the phone.
Yes. We stock parts for in addition to our CWS inventory, and we’re an authorized installer for more than a dozen manufacturer lines. If you have mixed windows in the same house, which is common in Royal Palm Beach where additions and remodels happened over decades, we can handle the whole job in one visit.
