CWS Energy-Efficient Windows in Fort Lauderdale: What to Know First
CWS energy-efficient window repair and replacement in Fort Lauderdale typically runs $340 to $1,800 per window, depending on whether we’re saving the existing frame or swapping in a full ENERGY STAR unit. Most CWS jobs are diagnosed and completed within three to five business days once parts are in hand. We’re an independent CWS service provider, not a manufacturer warranty center, and we give straight pricing before any work begins. Call (904) 913-5886 if your CWS windows are fogging, leaking air, or just not holding temperature the way they used to.
How CWS Products Fail - and How We Fix Them
CWS builds solid hurricane-rated frames, but energy performance lives or dies in the glass package and the seals. After years of working on CWS units across Fort Lauderdale, we see the same failure patterns repeat. Here’s what actually goes wrong:
- Seal failure on CWS Series 600 insulated glass. The two-pane assembly loses its argon gas fill when the edge seal degrades, and the telltale sign is condensation you can’t wipe off from the outside. In Fort Lauderdale’s humidity, that fog shows up fast. The fix is a new insulated glass unit, not a band-aid defogging that lasts six months.
- Low-E coating degradation on south-facing CWS windows. Homes along Las Olas and Rio Vista get relentless morning and midday sun. Over time, the Low-E metallic coating can develop a hazy, blotchy look that cuts visible light and raises indoor heat gain. We replace the glass pack with a current Low-E3 or equivalent spec, which blocks more UV than the original coating did.
- Frame gasket compression loss on CWS casement and awning windows. The rubber bulb seals that keep conditioned air in and humid air out flatten over years of compression cycling. You’ll feel a faint draft at the sash edges even when the window is locked. We re-gasket with OEM-spec material rather than shimming the hardware, because shims mask the problem instead of fixing it.
- Argon loss in CWS picture windows above 40 square feet. Large fixed units carry extra glass weight, which stresses the perimeter seal. We pressure-test suspect units with a spark tester and often find gas retention below 40 percent. At that point the window is a single-pane in disguise. We quote a factory-spec replacement IG unit, then verify the new fill before it leaves the shop.
- Condensation at the meeting rail of CWS sliding doors. The interlock between panels is a weak point for air and moisture transfer, especially on older CWS sliders with original weatherstripping. The fix is a new interlock seal and realigning the panels, which restores the thermal break and stops the inside puddling.
Our CWS Energy-Efficient Windows Process
Every CWS job follows the same sequence, whether it’s one fogged sash or a full house of replacements. Here’s how it runs:
- 1
Call and diagnosis. You talk to a live person. We ask what you’re seeing: fog, draft, heat, noise. We schedule a look at the actual windows, not a phone quote.
- 2
On-site inspection. Ed Winslow or a senior tech measures glass dimensions, checks gas fill, and inspects seals and frames. We photograph everything so you see what we see.
- 3
Parts decision. For CWS units under warranty, we coordinate with the manufacturer for covered glass. Out of warranty, we quote OEM-spec or equal-quality aftermarket glass, and we tell you the difference in plain terms before you spend a dollar.
- 4
The installation. We remove the failed unit, prep the frame, set the new glass with fresh bedding sealant, and re-secure the glazing stops. Floors get drop cloths; the area gets vacuumed.
- 5
Verification. We check for air leaks around the sash, confirm the argon fill if applicable, and run the window through a full open-close cycle. You inspect before we leave.
- 6
Paperwork and the Done Right Promise. You get the invoice with the exact price we quoted. If anything’s not right, the 36500-Day Done Right Promise means we come back and fix it. That’s the whole deal.

FAQs
In most CWS frames, the insulated glass unit can be replaced without pulling the entire window, which saves you hundreds per opening. The frame stays in place, and we install a new factory-spec IG unit. A full replacement only makes sense if the frame is rotted, racked, or you’re upgrading to a higher impact rating. Call (904) 913-5886 and we’ll tell you which applies to your window.
Glass replacement using OEM-spec units and manufacturer-approved methods does not void a CWS warranty, and we document everything so you have a paper trail. If your window is still under coverage, we coordinate with CWS directly. Ed Winslow has been through enough warranty claims to know exactly what documentation they require.
A foggy CWS window typically costs $340 to $620 to repair in Fort Lauderdale, depending on the glass size and whether it has Low-E or tinted coatings. That gets you a new sealed unit with the fog gone for good. For an exact number on your window, call (904) 913-5886 for a free estimate.
Most CWS glass units arrive within 5 to 10 business days once we confirm the exact dimensions and coating spec. Common sizes sometimes turn around faster. We’ll give you a delivery window when we quote the job, and that window is realistic because we order from suppliers we’ve used for over a decade.
Yes. If another company quoted you for CWS work, bring us the written estimate and we’ll review it at no charge.

Sometimes the honest answer is that your windows have more life in them, and you’d rather hear that now than after you’ve paid for work you didn’t need.
If your CWS windows are fogging, leaking, or fighting your air conditioner, call (904) 913-5886. We’ll send someone who knows CWS glass to your Fort Lauderdale home, give you a straight price, and stand behind the work with the Done Right Promise. The one down the road.
