CWS Window Installation: The Palm Beach Owner’s Guide
We install CWS window components across Palm Beach, and most CWS parts we swap run between $95 and $420 installed, depending on the component and your window series. If you’re noticing a sticky sash, a loose crank, fogged glass or a lock that no longer catches, you’re likely looking at a failed CWS window part, not a full window replacement. Call us at (561) 782-7525 and we’ll tell you over the phone whether it’s a part we can match same day.

Here’s the honest picture: most CWS parts give up in Florida’s salt and humidity long before the window frame itself does. The roller assemblies, balances, weatherstripping and lock mechanisms are the first things to go, and they fail in ways that are easy to misdiagnose. What looks like a warped frame is usually a dead balance or a corroded pivot bar. That’s the part we replace, and the window gets another decade out of it. Winslow Windows & Doors is an independent service provider, not affiliated with CWS, and we stock the CWS-compatible components that actually fit the units installed in Palm Beach homes.
Which CWS Models This Applies To
CWS has supplied a few distinct window families over the years, and each one takes different hardware. The older 6800 and 7100 series single-hung and horizontal roller windows, which you’ll find a lot of in 1980s and 1990s homes from El Cid down to the South End, use a specific style of spring balance and a plastic pivot shoe that cracks with age. The newer 9500 and 9700 series, common in condos along the Intracoastal, take a different balance tube diameter and a beefier roller with a stainless housing. You can’t swap parts between these lines, and the part numbers stamped on the balance or roller are how we confirm what you have before we quote anything.
Here’s the compatibility gotcha we run into every week in Palm Beach: a CWS window’s glass size is not the same as its balance spec or roller spec. Two windows that look identical from across the room can take different weight-rated balances because the sash changed thickness between production years. The only way to know is to read the stamp on the part itself or pull the sash and measure the balance tube diameter. If you’d rather not do that, call us and a technician will do it on site. For CWS specifically, we default to OEM-spec parts when they’re still available from our distributor network. When CWS has discontinued a part, which happens more often than we’d like, we use proven aftermarket equivalents that match the original specs, and we tell you which is which before you pay a dime.
Signs Your CWS Window Installation Is Failing
- The sash drops when you raise it, or won’t stay up at all. That’s a failed balance. Spring balances on single-hung CWS units in Palm Beach coastal air snap or lose tension after ten to fifteen years, and it’s never an alignment problem, it’s the part.
- The window doesn’t slide smoothly, or it grinds and grabs halfway across the track. Roller assemblies collect sand and salt grit along the coast, and once the nylon wheel seizes, the steel housing starts chewing the track. Replace the roller before the track needs machining.
- You close the lock and it barely catches, or the keeper plate spins loose. This one we see on older CWS 6800 series units where the original die-cast keeper corrodes at the screw points. The sash is fine; the lock hardware is not.
- Condensation trapped between the glass panes. In Palm Beach humidity, a failed CWS insulated glass seal shows up fast. Once the seal is breached, the argon or krypton fill escapes and the glass unit needs replacement, not repair.
- The crank operator turns but the vent sash doesn’t move, or it chatters when it does. CWS casement and awning operators strip their gears internally, and the only fix is a new operator matched to the window’s hinge geometry.
Every one of these symptoms has a distinct part number and a specific fix. You don’t have to know what the part is before you call. You just have to know what the window is doing.
Replacement Cost & What’s Included
For CWS window hardware installation in Palm Beach, here’s what we charge, installed, and what’s in the price.
- Single-hung spring balance pair: $95 to $165 installed
- Roller assembly pair (sliding or single-hung): $110 to $190 installed
- Lock and keeper assembly: $65 to $125 installed
- Casement or awning crank operator: $140 to $260 installed
- Insulated glass unit replacement (per sash, varies by glass and gas fill): $240 to $420 installed
The range comes down to which CWS series you have, how many parts need matching, and what the distributor charges us for the component on any given week. Every quote is parts plus labor, line-itemed, and the price we quote is the price you pay. No change orders. Our installation work is covered by the Done Right Promise: if it’s not done right, we come back and make it right. That’s the whole transaction.
DIY or Call Us?
You can safely do the diagnostic work yourself: read the sticker on the sash, see what the window is doing, and write down the part numbers if you can find them. That saves us both time. Where DIY goes wrong is in the swap itself. Window balances are under spring tension, and the release mechanism varies by brand series. If you don’t know how to relieve that tension before the sash comes out, the balance can snap back hard enough to take off a fingertip, and we’d rather you keep your hands. Glass unit replacement is its own thing entirely: CWS sashes take specific glazing bead profiles and shim tolerances, and a Palm Beach window that’s even slightly out of square after a DIY glass swap is going to leak in the next storm.
If the problem is a roller, a balance, a lock or an operator, call (561) 782-7525. We’ll match the part, quote you a fixed price over the phone, and typically have it installed the same day. Ed Winslow grew up in El Cid and he’s seen what salt air does to hardware, so we carry the parts that fail here, not the stuff that fails in Poughkeepsie.
FAQs
In Palm Beach’s salt air and humidity, CWS balances, rollers and lock hardware typically last 10 to 15 years before they need replacement, and glass seals often fail sooner on water-facing elevations. Coastal exposure shortens every hardware lifespan by about a third compared to inland installations. Call (561) 782-7525 and we’ll tell you if your symptom matches the typical failure window for your CWS series.
No, and we’d tell you if it could. Balances, rollers, operators and lock assemblies fail because an internal component has fractured or corroded, and there’s no field repair that puts that component back together. We replace the part with a matched CWS-spec or equivalent component, install it, and warranty the work through the Done Right Promise.
Most single-part CWS installations take 30 to 60 minutes once we’re at the window, and we carry the common balances, rollers and lock sets for Palm Beach’s most-installed CWS series on the truck. If we need to order a less common part, we’ll tell you the lead time before we schedule anything. Free estimates every time; call (561) 782-7525 for yours.
We stock the CWS-compatible parts that fail most often in Palm Beach, and we source OEM and aftermarket equivalents for the rest through our distributor network. We also match hardware for PGT, CGI and ES Windows when a neighbor needs those done. You never have to order your own part, ever. Call (561) 782-7525 and we’ll confirm what fits your window before we show up.
If you’ve got a CWS window acting up in Palm Beach, call (561) 782-7525 for a free estimate. A live person answers, day or night. My name’s on the truck. That’s the only guarantee you actually need. We’re the one down the road.
