CWS Custom & Geometric Windows in Miami: What to Know First
We provide independent CWS custom and geometric window repair and replacement throughout Miami, typically completing most jobs in a single visit. Depending on the opening and the hardware involved, work on a shaped CWS window usually runs between $220 and $1,400 when repair is possible, and a full custom replacement for an arched or geometric unit generally lands in the $1,800 to $6,500 range. We are an independent CWS service provider, not a factory-authorized dealer, which means we make parts and repair decisions based on your warranty position and what will actually hold up in South Florida. If you own a CWS window with a curved sash, an angled frame, or an oversized opening that other companies have declined to touch, call us at (561) 956-2754.
This page is written for Miami homeowners who have lived with CWS windows long enough to know which one binds in August and which one has been whistling since the 2020 season. It covers how these units fail, what we do differently, and what honest pricing looks like.

How CWS Products Fail - and How We Fix Them
CWS windows are built for coastal conditions, but Miami works on every window eventually. Salt air, afternoon thunderstorms, and the July sun test seals and hardware in ways no showroom ever will. Here are the failure patterns we see most often on custom and geometric CWS units in this city.
- Arched and radius units losing their seal at the apex. CWS architectural arched windows put the most stress on the top center of the bend, where the glass curve meets the frame. In Miami, the thermal cycle of hot days and sudden rain creates repeated expansion and contraction at that apex. We regularly find fogging or a subtle haze right at the top of the curve on CWS radius units in neighborhoods like Coral Gables and Pinecrest. Our fix is a full glass pack replacement with a sealant system rated for the humidity, not a stopgap defogging that returns in six months.
- Geometric window hardware binding on the acute angles. Triangles, trapezoids, and pentagons concentrate operating force on a single hinge point. CWS geometric casements and awnings, particularly the vented units, tend to bind at the smallest angle first. A homeowner often thinks the crank is failing when the real problem is the frame on the acute corner has shifted a few millimeters out of square. On these jobs we remove the sash, reset it to the frame’s actual geometry, and only then replace hardware that shows material wear.
- Oversized CWS openings showing diagonal stress cracks at the corner welds. On openings over eight feet, especially those facing Biscayne Bay or open water, wind load repeatedly tests the corner welds of the frame. Cracked corner welds are not a cosmetic issue. They let water into the wall cavity and eventually the interior side of the frame. Our crew has repaired more than a few of these on CWS picture windows in high-rise condos along Brickell and Edgewater, always documenting the original weld condition before and after.
- Weep system blockages on geometric shapes with a low sill angle. Shaped windows can trap water at the lowest point if the weep channels were not cleared of paint, sealant, or construction debris during the original install. This is common on CWS custom trapezoids and half-rounds above doors. The symptom is water pooling on the interior sill after a heavy storm, often years before the homeowner connects it to the window. Clearing the weep system and resealing the sill is a simple fix that prevents the frame from rotting from the inside.
- Roller and track wear on CWS sliding geometric units. Horizontal operating windows with angled profiles, like CWS parallelogram sliders, put uneven load on the rollers. The heavier end of the sash wears its roller faster, which makes the window drag and eventually jump its track. We replace rollers in matched pairs, re-shim the track alignment, and confirm the sash travels level. Never just one roller, because the second one is always about to go.
Our CWS Custom & Geometric Windows Process
A CWS custom window job has more moving parts than a standard double-hung. We follow the same sequence on every job so the homeowner knows what is happening and what it will take.
- 1
Call and describe the window. When you call (561) 956-2754, a live person answers and asks the questions that matter: the shape, the orientation, what the window does or does not do, and whether you have original paperwork or warranty documents. We do not route you to a call center.
- 2
Measure twice, then measure again. For geometric and radius units, our technician measures every leg of the frame, both diagonals, and the glass curve. Oversized openings get a deflection reading. This is where ordering mistakes get prevented.
- 3
Warranty and parts decision. We review your CWS warranty position with Dale Kessler, who has been reading warranty language for decades. We look at whether the unit is factory-covered, whether OEM parts are still available, and whether a quality aftermarket component will outlast what CWS originally shipped. The decision is always written down with prices.
- 4
The work. For repairs, we remove only what is necessary and keep the opening weather-sealed throughout. For replacements, the new unit is set, squared at every corner, and shimmed so the frame carries the load the way it was intended. If the pane is not true, the job is not done.
- 5
Test and document. We operate every moving window three full cycles, check all weep paths, and run water over the exterior sills. Both manufacturer warranty layers are registered in writing before the truck leaves the driveway, and you get a line-item summary of the work.
- 6
The 90-Day Done Right Promise. If anything we touched turns out wrong in the first 90 days, we fix it. No paperwork fights, no arguing about whose problem it is.
What CWS Custom & Geometric Windows Costs in Miami
Here are honest ranges for the CWS geometric and custom jobs we handle in Miami. These numbers reflect the market as of early 2026, not a national average that ignores South Florida labor and material costs.
| Job Type | Typical Cost |
|---|---|
| Glass pack replacement, arched CWS unit | $450 - $1,200 |
| Hardware replacement on geometric casement | $220 - $680 |
| Corner weld repair, oversized picture window | $500 - $1,400 |
| Weep system clearing and sill reseal | $180 - $380 |
| Full custom CWS replacement, arched or geometric | $1,800 - $6,500+ |
What moves the price on a CWS job is the shape itself. A radius unit costs more to bend, cut, and transport than a rectangle. An angled geometric in a high-rise means hoisting, building logistics, and sometimes a crane, which adds to the bill. Low-E and impact-rated glass run higher than standard clear. Access matters too. A fourth-floor window on a scaffold costs more than a ground-level opening. Every quote we write is itemized, and the price on the quote is the price on the bill. If it’s not worth putting in the contract, it’s not worth saying out loud. Call (561) 956-2754 for your free estimate.
Why Miami Homeowners Call TruePane Windows & Doors for CWS Work
Dale Kessler learned glazing from his father in a two-bay garage in Columbus, Ohio, and has been working glass long enough that little surprises him. He and our crew have served Miami for more than a decade, from Coral Gables bungalows to high-rises overlooking Biscayne Bay, and we have repaired CWS units that other companies would not touch because the shape was too difficult or the warranty too tangled.
We are an authorized installer for more than a dozen manufacturer lines including Andersen, Pella, Marvin, Milgard, PGT, CGI, and ES Windows. That matters when a CWS unit needs a full replacement and the honest recommendation is a product from PGT, CGI, ES Windows, or ECO Window Systems that will hold up better in this climate. We quote manufacturer lines side by side on paper so you see exactly what you are buying, and we register both warranty layers before we leave. We have served local communities for over 42 years, and we plan to be answering this phone in thirty more. A live person picks up 24 hours a day, seven days a week. If we make a mistake, the 90-Day Done Right Promise means we stand behind it, in writing.
FAQs
Yes. We review the warranty language on your specific CWS unit and determine whether the repair or replacement falls under manufacturer coverage. If the claim is valid, we document the issue and guide you through the process. If the warranty has lapsed or was voided by the original install, we give you an itemized repair quote. Call (561) 956-2754 and we’ll tell you what your warranty actually covers.
Sometimes. CWS has produced multiple model lines over the years, and OEM availability depends on the series and the vintage. When OEM parts are available and they are the best option, we order them. When original parts are no longer made or were weak from the start, we source quality aftermarket components sized to your exact opening. The parts decision is always written on the quote, not made on the fly. Call (561) 956-2754 to find out what is available for your unit.
If the frame is square, the glass pack is the only problem, and the hardware is intact, repair is usually the better investment. If the frame corner welds are cracked, the sash is twisted out of plane, or the glass has failed at the curve and the unit is more than 15 years old, replacement often costs less over time and gives you a fresh product warranty. We give you both numbers side by side before you decide. Call (561) 956-2754 for an honest comparison.
Most CWS repair work is completed in a single visit once the parts decision is made and any required materials are on the truck. Full custom replacements depend on fabrication time for shaped glass, which typically runs two to four weeks from order to install. We’ll tell you the timeline before we schedule anything. Call (561) 956-2754 and we’ll give you a straight answer.
For full replacements that require structural changes or impact-rated upgrades, we pull the permits and schedule the inspections. For repair-only work, permits are generally not required under Miami code, but we’ll confirm the specific requirements for your property and your municipality. Everything we permit gets inspected and approved before we consider the job done. Call (561) 956-2754 with your address and we’ll tell you what applies.
