AfterCWS Custom & Geometric Windows in Miami: What to Know First
CWS custom and geometric windows in Miami are specialty units - arched tops, radius corners, trapezoids, ovals, and oversized openings that standard square windows can’t fill. As an independent CWS service provider, Winslow Windows & Doors handles repair, replacement, and new installation of these shaped units across Miami-Dade, typically turning around a custom CWS order in 3 to 6 weeks depending on the manufacturer’s production queue. Costs for a single custom geometric CWS window start around $900 installed and climb from there based on size, glass package, and whether impact rating is required.
If you own a CWS shaped window that’s fogged, leaking, or won’t close cleanly, call (863) 946-5039. We’ll tell you honestly whether it’s a repair or a replacement - and what it should cost before we touch anything.
Key Takeaways:
- We’re an independent CWS service provider, not a factory authorized dealer - which means we recommend the right fix, not the one tied to a franchise agreement.
- Custom and geometric CWS units are individually fabricated, so lead times and costs vary more than stock window work.
- Ed Winslow personally reviews every CWS project quote before it reaches you.
- Free estimates, upfront pricing, and the 36500-Day Done Right Promise on every CWS job.
How CWS Products Fail - and How We Fix Them
CWS builds a solid window, but Miami’s salt air, humidity, and hurricane cycles find the weak points in any product. Here’s what we see most often on custom and geometric CWS units in local homes:
- CWS Series 900 arched windows - seal failure at the apex. The curved top of an arched CWS unit concentrates stress at the crown, and after enough Miami heat-soak cycles, the insulated glass seal gives way first up top. You’ll see fogging that starts at the curve and spreads downward. We replace the IGU (insulated glass unit) and rebalance the sash so the replacement doesn’t inherit the same stress pattern.
- Custom radius corner units - frame racking in older block homes. Miami’s concrete-block construction settles, and when it does, a geometric CWS window with radius corners binds at the lower arc. Homeowners first notice the crank or sash getting harder to operate. The fix is often shimming and re-squaring the frame, not replacing the glass - we’ll tell you which one before quoting either.
- Oversized CWS trapezoid windows - flashing failures at the wide sill. Big trapezoid units over picture windows or entryways have a lot of sill to shed water from Miami’s afternoon downpours. If the original flashing was cut even slightly short, water wicks into the rough opening and rots the sub-sill. We pull the unit, rebuild the sill pan, and reinstall with full-width flashing - done right, it won’t leak for the life of the window.
- Geometric CWS units with muntins and grids - internal grid rattle. Shaped windows with decorative grids sometimes develop a rattle where the grid clips meet the curved frame. It’s cosmetic, but it drives some customers crazy. We can usually resecure the clips through the frame without replacing the entire sash, which keeps a small annoyance from becoming a four-figure replacement.
- CWS impact-rated geometric windows - gasket compression set. Impact-rated units rely on heavy gaskets to seal against wind-driven rain. In Miami’s heat, those gaskets compress over time and lose rebound, which shows up as weeping at the lower corner during tropical storms. We replace the gaskets with OEM-equivalent material that maintains the impact rating and stops the leak. This is a repair most people don’t know is possible - and it’s a fraction of the replacement cost.
Our CWS Custom & Geometric Windows Process
Here’s how a CWS geometric window job goes when you call Winslow Windows & Doors:
- 1
Call and talk to a person. No phone trees, no call centers. Someone answers 24/7, so when you call at 9 p.m. because your CWS arched window started fogging, you get a real response and a scheduled visit.
- 2
On-site diagnosis. A background-checked, uniformed technician arrives, measures the unit, checks the glass seal, frame condition, and operation. We identify the specific failure mode before discussing any fix.
- 3
Parts decision. We tell you whether OEM CWS parts are available and when aftermarket is the smarter call - especially for older units where an OEM replacement sash might cost more than a quality aftermarket replacement installed.
- 4
Written quote with line items. Upfront pricing. No vague allowances. You see the unit cost, labor, flashing, and disposal separately.
- 5
The work. Custom CWS units get ordered to spec, installed plumb and square, flashed correctly for Miami weather, and tested for operation before we clean up.
- 6
The guarantee. Every job carries the 36500-Day Done Right Promise: if it’s not right, Ed makes it right. That’s not a limited-time warranty pitch - that’s how this company has operated since 2011.
What CWS Custom & Geometric Windows Costs in Miami
Custom and geometric CWS windows in Miami are priced per unit, not by the square foot like stock replacements. Here’s what we typically see:
- Repair of a fogged CWS arched IGU: $275 to $650, depending on size and whether the frame needs rework (rebuilding a sub-sill adds $150-$300).
- Replacement of a single custom CWS geometric window, non-impact: $900 to $1,800 installed.
- Replacement of a custom CWS geometric window, impact-rated: $1,800 to $3,200 installed, depending on size, shape complexity, and glass package.
- Full gasket and hardware refresh on an existing CWS geometry unit: $200 to $500.
What moves the price: the number of curved edges, whether impact glazing is required (most Miami replacements are), lead time stacking (custom shapes queue behind stock production), and whether the existing rough opening needs reframing from water damage. Every quote is line-item free, and if you have a written estimate from another company, bring it in - we’ll give you a free second opinion on it.

Why Miami Homeowners Call Winslow Windows & Doors for CWS Work
Ed Winslow grew up in Hialeah, where summer storms rolling off the Everglades taught him early that a bad window wasn’t just an eyesore - it was a liability. He learned glazing and framing through the building trades program at Miami Dade College, spent years installing across Miami-Dade before putting his own name on a truck, and he’s been the guy neighbors call when the hurricane forecast hits and their old aluminum frames suddenly feel less than adequate.
We know CWS custom and geometric windows because we’ve repaired and replaced hundreds of them across Miami - from Coral Gables arcs to Kendall trapezoids over entry doors. When a CWS unit isn’t the right call anymore, we can compare it honestly against PGT, CGI, ES Windows, and ECO Window Systems because we install all of them. And every CWS job we take carries the same promise: Ed’s name is on the door - and on every job we do. If it’s not done right, we come back. That’s been the standard since 2011, and unlike a franchise chain, there’s no ticket number between you and the owner.
The one down the road.
FAQs
No. As an independent CWS service provider, we use OEM-equivalent parts and follow manufacturer installation standards for geometric units, which keeps your original warranty intact. If a sealed unit fails under CWS’s own glass warranty, we’ll even help you file the claim before quoting any out-of-pocket repair. Call (863) 946-5039 and we’ll walk you through what’s covered.
Expect 3 to 6 weeks from order to install for a custom CWS arched, radius, or trapezoid unit, depending on the factory queue and glass package. Repairs on existing units are usually completed same-day to three days once we’ve diagnosed the problem and sourced parts. We’ll give you a solid production timeline at the estimate so you’re not left guessing.
If the frame is square and undamaged, repairing the failed IGU usually saves you 50 to 60 percent versus replacing the entire unit. If the frame is racked, the sill is rotting from water intrusion, or the unit is over 15 years old and out of production, replacement - which we can install a comparable custom unit for - makes more sense. We’ll quote both options and tell you which one we’d pick on our own house.
Yes. We’ve installed and repaired CWS trapezoids and curved-top assemblies up to 12 feet wide across Miami homes. Oversized openings require extra framing support, heavier glass, and often a crane or two-person lift crew - we factor all of that into the upfront price so there are no surprises on the invoice.
No. The number on your written estimate is the number on your final invoice, unless you ask us to add scope after the quote. We do not do change orders. If we find hidden rot behind a CWS geometric frame, we stop, show you what we found, and give you a fixed price to fix it before anything else proceeds - that’s the 36500-Day Done Right Promise in its simplest form.
