CWS Custom & Geometric Windows in Three Lakes: What to Know First

We provide independent CWS custom and geometric window service in Three Lakes, with most measured surveys scheduled within 48 hours and written quotes delivered before any work begins. Typical CWS custom installations run $1,800-$4,500 per opening depending on shape complexity, impact rating, and whether the rough opening needs reframing. We do not quote over the phone for custom work; the measurement and the quote are the same document, and you keep both.

This page is for Three Lakes homeowners who already own CWS windows and need custom shapes, arched replacements, or oversized geometric units installed or serviced. If your home backs up to the Killian Corridor or sits on one of the interior lakes where the afternoon sun loads are severe, the glazing specification matters more than the frame brand. Call (786) 808-5792 to schedule your measured survey.

How CWS Products Fail - and How We Fix Them

• CWS 3120 Series casements in radius-top configurations: The arched sash on these units often develops seal failure at the springline where the curved meeting rail meets the straight stile. We’ve replaced dozens in Three Lakes where the thermal break separates and condensation forms between the panes. Our fix: measure the exact chord and rise, order OEM insulated glass from CWS’s Miami distribution center, and re-glaze with new setting blocks sized to the revised weight load.
• CWS 5400 Series fixed geometric shapes with integral blinds: The internal lift mechanism binds in high-humidity conditions, which is most of the year in Three Lakes. The blind cassette is factory-sealed; we do not attempt field repair. Instead, we source the complete sash assembly by serial number and swap it as a unit, preserving the impact rating and the original NOA documentation.
• CWS 8200 Series oversized fixed triangles and trapezoids: These show stress cracks at the corner reinforcements when the substrate framing expands in summer heat. The 8200 uses a heavier wall extrusion that doesn’t flex as readily as PGT’s equivalent. We sister the rough opening with treated lumber, install backer rod and structural silicone at the perimeter, and specify Neoprene setting blocks rather than PVC to accommodate thermal movement.
• CWS impact-rated custom circles and ovals: The curved steel reinforcement channel can corrode at the weld points if the weep system clogs with palm debris, common in Three Lakes lots with mature landscaping. We clean the weeps with compressed air and a borescope, treat any surface corrosion with phosphoric acid converter, and replace the reinforcement if pitting exceeds 1/16 inch.
• CWS transom and sidelight assemblies in double-door configurations: The geometric lite above a CWS entry door often settles independently of the door frame, breaking the sealant joint. We remove the transom, shim the rough opening to within 1/8 inch of plumb, and reinstall with backer rod and Dow 795 silicone that maintains adhesion through the wet season expansion cycles.

Our CWS Custom & Geometric Windows Process

1. 1
   Measured survey: Sonia Raman or a verified crew member arrives in uniform with license number visible, records rough opening dimensions to 1/16 inch, notes plumb and square deviations, and photographs existing conditions. You keep the survey document.
2. 2
   Glazing specification: We specify glass package by orientation and exposure. Homes on Three Lakes’ western shore get Solarban 70XL or equivalent low-E with 0.25 SHGC; northern exposures get higher VT glass for daylighting. The written quote names the exact IG makeup and the U-factor.
3. 3
   Parts decision: For CWS units still under OEM warranty, we use CWS factory parts and register the claim. For out-of-warranty work, we evaluate quality aftermarket options from our verified suppliers, never substituting without written approval.
4. 4
   Fabrication and delivery: Custom CWS geometric units typically fabricate in 4-6 weeks. We coordinate delivery to avoid siting glass on a Three Lakes job site during hurricane watch.
5. 5
   Installation and testing: Crew installs per Miami-Dade NOA, seals with specified backer rod and sealant, and tests operable units for smooth function. We photograph every stage; you receive the photo record.
6. 6
   Documentation and guarantee: Final invoice matches the written quote exactly. The 365-Day Done Right Promise is stamped on the paperwork. Measure once, quote it straight, install it right - nothing else belongs on the invoice.

We’ve served Three Lakes for years, including homes backing up to the Killian Corridor where the afternoon sun loads are no joke and the wrong glazing choice shows up on your FPL bill every month. Sonia Raman reads a rough opening accurately the first time and specifies impact-rated units that meet Miami-Dade Notice of Acceptance requirements without upselling product a house doesn’t need.

Every job carries the 365-Day Done Right Promise under the Haven Standard. Our crews are background-checked, uniformed, and identified by license number before arrival. We also specify PGT, CGI, ES Windows, and ECO Window Systems when the opening calls for a different performance tier or price range. The measured survey is yours to keep; the written quote cannot differ from it.
