CWS Windows & Doors in South Palm Beach, FL | Winslow Windows & Doors
We provide independent CWS window and door service across South Palm Beach, from single-pane 3900 slider repairs to full-frame Impact Windows - South Palm Beach replacements. What makes our CWS work different here is simple: we’ve spent years pulling apart original CWS units inside oceanfront condos on this barrier island, so we know exactly how salt and wind attack these specific frames. Call (561) 782-7525 for a straight answer on repair versus replace. Ed Winslow has been doing this since 2011, and we know CWS better than most factory reps.

Why South Palm Beach Residents Choose Us for CWS Service
Most window companies in Palm Beach County will quote a CWS repair once, realize the interlock is proprietary, and quietly walk away. We don’t. Our crews have serviced CWS 3900 Series sliders, fixed pictures, and 450 Series impact casements up and down the condo towers along our Window Installation in South Palm Beach oceanfront for years. Ed grew up in El Cid, just across the water, and spent his early trade years watching salt air destroy original aluminum frames on older buildings. He learned glazing fundamentals at Palm Beach State College, then worked his way from glazier’s helper to the guy homeowners call when the last contractor left a mess.
We carry OEM-compatible CWS interlock, roller, and weatherstripping parts where inventory still exists. When a frame is too far gone, we say so and quote a full-frame impact replacement instead of stringing you along with patch jobs. We’re CWS sales & service specialists, not a franchise shop that sees one CWS unit a year. And every call is answered by a live person, 24/7. No voicemail loops. Ed’s name is on the door, and on every job we do.
Common CWS Windows & Doors Problems We Solve in South Palm Beach
- Salt-spray pitting on 3900 aluminum frame tracks. The whitish crust you see on the meeting stiles of your 3-lite slider is electrolytic corrosion from the dual ocean/Intracoastal salt exposure. Once the track pits, rollers hang up and the sash gets stiff. If the frame metal is still sound, we clean, neutralize, and install marine-grade rollers. If pitting has breached the track wall, replacement is the honest call.
- Corrosion-seized stainless roller assemblies. We regularly pull CWS horizontal sliders in South Palm Beach where the stainless steel roller axle has corroded inside the housing. The nylon glide strips, then the adjustment screws. This is textbook barrier-island failure – we see it on buildings along West Boynton Beach Boulevard constantly.
- Bowed interlock channels on 3-lite rollers. Decades of wind load off the Atlantic push on the center stile and bow the interlock channel. The operable sashes go out-of-square, and you get air and water through the center. We re-square what’s salvageable and replace what isn’t.
- Perished glazing seals and butyl bedding on fixed picture frames. Fogging between panes, cracked sealant at the sill, water staining on the interior drywall below. On CWS fixed units from the 1970s and 1980s, the butyl tape has turned to dust and the wedge gasket has shrunk.
- Failed tie-down hardware at the sill and head. In high-rise units, the tie-downs anchoring CWS frames to the slab take a beating from wind uplift. We check every anchor point on any service call, because a loose tie-down in a South Palm Beach high-rise is not a minor issue.
CWS Service in South Palm Beach: What Local Conditions Mean for Your Equipment
Here’s the thing most window companies from Boca or West Palm miss entirely: South Palm Beach sits on a narrow Atlantic barrier island with the ocean on one side and the Intracoastal Waterway on the other. That means your CWS windows and doors are getting hit with salt-spray corrosion from both directions simultaneously. Not one side. Both. A CWS 3900 Series frame that would last 25 years in Wellington or Royal Palm Beach will show significant pitting here in 12 to 15. We see it on buildings along Willoughby Road and the side streets off Boynton Beach Boulevard. The stainless hardware seizes, the aluminum tracks pit, and the sealants degrade in a fraction of the time. For CWS owners, that means the decision is rarely cosmetic. You’re either holding a frame over until your condo board schedules a building-wide re-glaze, or you’re replacing with impact-rated products and marine-grade hardware because anything less is throwing money away. Our tech was on a 5th-floor unit just off Willoughby Road where an original CWS 3900 3-lite horizontal roller had seized mid-track. Salt had pitted the aluminum interlock and corroded the bottom roller axle so the center sash hung up on the sill. We pulled the sashes, replaced the roller assembly with a marine-grade aftermarket set and cleaned the track channels, then re-squared the interlock so the center stile closed flush. The owner got another season out of it while his board reviews a full-building impact re-glaze. That’s the kind of repair-versus-replace call you can’t make from a brochure.
CWS Models & Products We Service in South Palm Beach
We work on every CWS line still found in South Palm Beach’s condo stock. The 3900 Series aluminum single-hung is the original builder grade from the 1960s through the 1980s – most of what we see. The 3900 Series horizontal slider in 2-lite and 3-lite configurations is even more common on oceanfront units. The 3900 Series fixed picture frame shows up as oversized non-impact glazing, and the 450 Series thermally broken impact casement is what many buildings upgraded to after Hurricane Wilma or later code changes. For original CWS interlock, roller, and weatherstripping parts, we source OEM where inventory still exists. For frames with pitted tracks or bowed interlocks, quality aftermarket rollers and marine-grade weatherstripping are often the cost-effective hold-over while an HOA engineers a building-wide re-glaze. We’re candid about which is which, and our quotes name the parts either way.
CWS Service Pricing in South Palm Beach
CWS service in South Palm Beach runs about $210 to $490 per opening for most roller swaps, track cleaning, weatherstripping replacement, and interlock adjustments.

FAQs - CWS Windows & Doors in South Palm Beach
Yes, that whitish crust is aluminum pitting from the dual ocean/Intracoastal salt exposure specific to this barrier island, and it can often be repaired. If the frame metal is still sound, we clean and neutralize the corrosion, then install marine-grade rollers. If the pitting has breached the track wall, the frame is done and we’ll quote a full-frame replacement. Call (561) 782-7525 for an exact assessment. Estimates are free.
No. On most CWS fixed picture frames, the glass is held in place by a removable stop or a wedge gasket, not by the frame itself. We can typically reglaze the panel in place. The exception is when the surrounding aluminum has corroded so badly that the stop won’t release – then we have to pull more than just the glass.
Because South Palm Beach’s entire residential inventory sits inside condo associations whose architectural boards are required to verify that any replacement glazing meets Palm Beach County wind-borne debris impact standards. The Florida Product Approval number is the legal proof. A bid without the number for that exact opening is dead on arrival, and we submit ours as part of every quote.
It depends on which interlock and how the sashes are stacked, but in most cases we can pull the affected operable panel and leave the fixed panels in place. If the interlock damage is at the center stile and the frame has bowed, we may need to pull all three to re-square the unit. We quote the exact scope before touching a screw.
Three things: frame track pitting that has breached the aluminum, bowed interlocks that can’t be re-squared, and failed tie-down anchors at the sill or head that compromise the entire frame’s wind resistance. If any of those applies, a full-frame impact replacement is the honest fix. Call (561) 782-7525 and we’ll tell you which path fits your unit and your board’s timeline.
