1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

CWS Custom & Geometric Windows in North Miami: What to Know First
We install and service CWS custom and geometric windows in North Miami as an independent CWS service provider. Most custom CWS units we measure are fabricated and installed within 4 to 6 weeks, with written pricing delivered at the first survey visit. Our quotes for CWS arched, curved, and oversized openings in North Miami typically run $2,800 to $7,400 installed, depending on glazing specification and whether the opening requires structural reinforcement.
This page is for North Miami homeowners who already own CWS products or are comparing CWS against PGT, CGI, and other lines we carry. If you need shaped windows that must also meet Miami-Dade’s HVHZ requirements, call (786) 706-0468 to schedule your free measured survey.
How CWS Products Fail - and How We Fix Them

- CWS 4120 Series casements with curved tops: The radial mullion joints in the arched portion take stress differently than rectangular frames. We see seal fatigue at the springline where the curve meets the jamb, usually after 6 to 10 years in North Miami’s salt-air exposure. We replace with OEM radial gaskets and add a secondary silicone bed at the springline, documented in the photo record.
- CWS impact-rated geometric units with laminated glass delamination: The polyvinyl butyral interlayer can fog at the edges when the aluminum spacer isn’t sealed to CWS’s factory spec. This happens most often on south-facing trapezoids in North Miami Shores. We source the correct CWS spacer profile or a verified equivalent, re-glaze the unit, and test to the original design pressure.
- CWS 8100 Series oversized fixed windows: The thermal break separates from the extrusion when the frame flexes under wind load. In North Miami, this shows up after named storms when the unit was never breached but the frame cycled. We assess whether the break can be field-repaired or if the sash requires replacement, and we document the decision criteria in writing.
- CWS custom circle-top inserts with weep-path blockage: The curved sill profile doesn’t drain as aggressively as standard rectangular sills. Pine needles from North Miami’s mature oak canopy compound the problem. We clear the weeps, verify the pressure balance, and show the homeowner the maintenance interval on the photo record.
- CWS geometric units with mismatched hardware: Previous installers substituted generic multipoint locks when CWS discontinued a lever style. The backset and cam positions don’t align, so the lock doesn’t fully engage. We track the correct CWS hardware or machine an adapter from documented specs, never forcing a mismatch.

AfterOur CWS Custom & Geometric Windows Process
- 1
Measured survey you keep. We arrive with the laser, the story pole, and a printed template for your specific CWS series. Sonia Raman checks every rough opening twice before touching a shim. You leave with the dimensional record.
- 2
Written scope and price. The measurement and the quote are the same document. Haven Clause 1 means no verbal estimate, no “we’ll see when we get into it.”
- 3
Parts decision with evidence. We identify whether your CWS unit needs OEM extrusions, OEM glass, or verified aftermarket equivalents that won’t void remaining warranty coverage. We explain the trade-off in writing.
- 4
Fabrication and installation. Background-checked, uniformed technicians with license numbers on the page. Verified crews, Haven Clause 3. The person at your door matches the person on the record.
- 5
Testing and documentation. We operate every moving part, check the sightline for square, and photograph the completed condition. You receive the photo record and the 365-Day Done Right Promise, stamped under the Haven Standard.

Cleanup and final invoice. The written price before work started and the final invoice are the same document. No surprises, Haven Clause 5.
What CWS Custom & Geometric Windows Costs in North Miami

| Scenario | Typical Range |
|---|---|
| CWS custom arched window, standard impact glazing, existing opening | $2,800 - $4,200 |
| CWS geometric trapezoid or circle-top, HVHZ-rated, new construction | $3,400 - $5,600 |
| CWS oversized fixed unit, 60+ sq ft, laminated glass, structural reinforcement required | $5,200 - $7,400 |
| CWS custom curved window, radius under 24 inches, specialty fabrication | $4,100 - $6,300 |
What moves the price: glazing specification (annealed, laminated, or insulated laminated), whether the opening needs a new header or sill pan, and whether the CWS series is current production or requires custom fabrication from archived extrusion dies. Structural reinforcement for oversized units in North Miami’s 175 mph wind zone adds material and engineering review.

Why North Miami Homeowners Call Sightline Windows & Doors North Miami for CWS Work
We’ve worked the Biscayne corridor near the North Miami Public Library long enough to know how aging aluminum frames behave in this specific salt-air environment. That retrofit stretch taught us more about CWS and competing products than any classroom did.
Our 365-Day Done Right Promise is written into the Haven Standard, not offered as a courtesy. If it’s not done right, we make it right. Our technicians are uniformed, background-checked, and identified by license number before arrival. Live phone coverage, 24/7.
Because we also specify PGT, CGI, ES Windows, and ECO Window Systems, we can show you direct comparisons when CWS isn’t the right fit for your opening. We specify by performance tier and price range, not by margin. Measure once, document everything, explain the rest in plain English.
FAQs

It depends on what failed and who does the work. CWS warranties the extrusion and glass against manufacturing defect; our repairs address installation or environmental failure modes outside that coverage. We document whether your issue is warranty-eligible before we start, and we use OEM or verified-equivalent parts so we don’t compromise any remaining factory coverage. Call (786) 706-0468 and we’ll review your situation.
Standard CWS custom shapes run 4 to 6 weeks from measured survey to installation. Radius windows under 24 inches or units requiring archived extrusion dies can extend to 8 weeks. We quote the lead time in writing on the same document as the price, so you know before you commit. Call (786) 706-0468 for a current schedule.
Usually. CWS maintains extrusion dies for current series and several discontinued lines. For older North Miami homes with CWS units from the 2000s, we verify color match against the factory anodize chart or powder-coat sample before ordering. If the series is obsolete, we show you the closest visual and performance equivalent from CWS or another line we carry. Call (786) 706-0468 to bring us a photo or sample.
Replace when the thermal break has failed structurally, the frame is bent from impact, or the cost of repair exceeds 60 percent of replacement. Repair when the failure is isolated to glass, gaskets, or hardware. We make this calculation in writing, with both options priced, so you decide from evidence rather than pressure. Call (786) 706-0468 for both numbers.
We stock common CWS hardware, gaskets, and glazing components for rectangular units. Geometric and custom CWS parts are fabricated to order because the radius, angle, or dimension varies per opening. For urgent weather exposure, we can board and seal same-day while the custom part is in production. Call (786) 706-0468 to discuss temporary protection and permanent repair timing.
