CWS Custom & Geometric Windows in Miami Beach: What to Know First
CWS custom and geometric windows in Miami Beach are specialty impact-rated units that most contractors won’t touch, but our team works on them regularly. We’re an independent CWS service provider, which means we’re not bound by factory service schedules or inflated OEM pricing. Typical turnaround for a custom or geometric CWS repair runs three to seven business days once we’ve assessed the opening, and every job starts with a free estimate at (863) 656-0462.
This page is for Miami Beach homeowners and condo owners who have CWS windows with arched tops, radius corners, trapezoids, or oversized openings that need repair, reglazing, or replacement. If you’ve already called two or three companies and gotten hesitation on the other end of the line, you’re in the right place. Ed Winslow grew up in Miami and has spent nearly three decades learning what this salt-air climate does to a window that wasn’t installed correctly. We work on CWS products regularly, from older condo buildings near the Faena District to single-family homes just off the boulevard.
How CWS Products Fail - and How We Fix Them
- CWS 500 Series architectural windows - seal failure around arched and radius glass. The curved glass units on CWS 500 Series windows put constant stress on the polyisobutylene seal. In Miami Beach’s humidity, a micro-fracture in that seal pulls moisture into the airspace within two or three years if the sash wasn’t perfectly shimmed. You’ll see fogging that comes and goes with the temperature. We replace the insulated glass unit (IGU) with a radius-matched piece and reset the sash to CWS’s original tolerance. The fix isn’t a reglaze; it’s a full IGU swap.
- CWS 800 Series impact windows - cracked laminated glass without impact. This one surprises people. Laminated impact glass can develop stress cracks from frame movement, not flying debris. In older Miami Beach buildings where the concrete has shifted or settled, the CWS 800 frame gets torqued, and the glass takes the load. We see hairline cracks running from the corner of a trapezoid or oversized picture window. The fix is new laminated glass plus frame anchoring - just swapping the pane doesn’t stop the next crack.
- CWS 950 Series low-E windows - thermal expansion popping at the corners of shaped units. Triangular and pentagon windows in the 950 Series have mitered corners that catch direct morning sun. South Florida’s UV load makes the vinyl move, and over time the corner welds can develop hairline gaps that let water in during a hard Miami Beach storm. We re-weld or reinforce those corners with an internal brace, then reseal with marine-grade sealant. The factory won’t send a tech for this; we do it on-site.
- CWS 400 Series single-hung - balance shoe failure in oversized openings. Oversized CWS 400 single-hungs wear out their balance shoes faster than standard units, especially in Miami Beach condo towers where windows get cycled daily for the ocean breeze. Symptom: the sash won’t stay up, or it slams when you lower it. We replace the balance shoe and spring with weight-rated parts that actually match the sash - many aftermarket parts are undersized. On a custom opening, that mismatch is the difference between a window that works for five years and one that fails again in nine months.
- CWS horizontal roller - track warping on custom-width units. Long horizontal rollers - think 96 inches or wider - put a lot of unsupported track out there. In Miami Beach’s heat, aluminum track can warp or bow, and the roller jumps the rail or binds mid-slide. We see this on CWS models with custom widths that the original installer didn’t brace properly. We straighten or replace the track, add intermediate supports where the opening allows, and the door glides like it should.
Our CWS Custom & Geometric Windows Process
- 1
Call and talk to a live person, day or night. You reach us directly at (863) 656-0462. We ask about the window, the shape, the symptom, and the building. If it’s a condo, we ask about association requirements up front so we don’t waste your time.
- 2
On-site inspection with real measurements. We measure the existing unit to the sixteenth of an inch - radius, chord length, frame depth, and glass type. For custom and geometric windows, every dimension matters. We photograph the opening and the existing anchors.
- 3
Parts decision: OEM where it matters, quality aftermarket where it’s smarter. CWS OEM glass and frames preserve the manufacturer warranty on newer units, so we quote OEM when the warranty is active. For older CWS windows where the warranty has expired, we source aftermarket IGUs and hardware that match or exceed the original spec, at a meaningfully lower price. We lay out both options honestly.
- 4
We tell you the exact price before any work starts. No ranges at contract time. No change orders when we’re halfway through. The number we quote is the number you pay.
- 5
Surgical repair, not a demo crew. We protect the opening, remove the damaged sash or glass with minimal disruption, clean the frame channel, set the new unit, re-anchor, and seal. Uniformed, background-checked techs on every job - you know who’s at your door before the truck pulls up.
- 6
Test, clean, and walk you through the work. We cycle the sash, check the drainage weep system, confirm the seal, and clean the glass and frame. Then we walk you through what we did and what to watch for. Every job is covered by the 36500-Day Done Right Promise: if it’s not done right, we come back and make it right.
What CWS Custom & Geometric Windows Costs in Miami Beach
Here’s the honest math, because you can’t find this on CWS’s site:
- Seal replacement or reglazing a CWS radius or arch unit: $450-$900 depending on the radius and access. Ground-floor openings cost less; upper-story condos with exterior-only access cost more.
- IGU replacement in a CWS 500 or 800 Series shaped unit: $900-$1,800. Curved or trapezoid IGUs are custom-cut; the glass alone runs $35-$55 per square foot before labor.
- Balance shoe or hardware replacement on a CWS 400: $185-$385 per sash, including parts and labor.
- Full replacement of a custom CWS impact window (arched, radius, or oversized): $2,800-$7,500 installed, depending on size, glass package, and whether the opening needs reframing. Hurricane-rated laminated glass is the bulk of the cost.
What moves the price: window height and access (lifts, scaffolding, condo equipment), whether the opening needs structural correction, and whether you choose OEM or high-quality aftermarket parts. Condo associations in Miami Beach often require specific glass packages, so we pull the association specs before we quote. Senior or veteran? You get 10% off, permanently.

FAQs
On CWS windows still under the manufacturer warranty, we use OEM glass, frames, and hardware so the warranty stays intact. If the warranty has expired, we’ll quote both OEM and quality aftermarket options and let you choose. Call (863) 656-0462 and we’ll help you figure out the warranty status.
Custom curved or radius IGUs typically take three to seven business days to fabricate once we’ve confirmed measurements. The install itself is usually a one-day job unless the opening needs structural work. We’ll give you a clear timeline before we start, and we hold to it.
Replacement typically runs $2,800 to $7,500 installed, depending on size, shape, glass package, and access. Repairs run $185 to $1,800. The best way to know is a free estimate - call (863) 656-0462 and we’ll measure and price it exactly.
We do both, and we’ll tell you straight when repair is throwing money at a window that’s already past its service life. When replacement makes more sense, our PGT and CGI lineups often give Miami Beach homeowners better long-term value than sticking with CWS OEM. We’ll walk you through the numbers either way.
No. The price we quote is the price you pay - no vague allowances, no change orders when we’re halfway through. If we find something structural, we stop and talk to you before spending another dollar. That’s been the policy since 2011, and it’s why Miami Beach neighbors leave our trucks their phone numbers.
Ready to get your CWS custom or geometric window fixed for good? Call Winslow Windows & Doors at (863) 656-0462 for a free estimate. Ed’s name is on every job we do. That keeps us honest.
