1. Choose your installer

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 South Miami Heights: What to Know First
We provide independent CWS custom and geometric window service in South Miami Heights, typically completing measured surveys within 48 hours of contact and delivering written, line-item pricing before any product is ordered. Most custom CWS units run 4-6 weeks from signed quote to installation, with shaped and oversized openings at the longer end of that range. We are not affiliated with or authorized by CWS; we are an independent CWS service provider who specifies, measures, and installs these units under our own Haven Standard.
This page is for South Miami Heights homeowners who already have CWS windows and need custom shapes, arched replacements, or oversized geometric units, or who are comparing CWS against other impact-rated lines for a new opening. If you are working from another company’s quote, we will review it at no charge. Call (786) 481-0414 to schedule your measured survey.
How CWS Products Fail - and How We Fix Them
- CWS 3120 Series fixed geometric units: The thermal break in the aluminum frame separates at the weld corners after repeated heat cycling in South Miami Heights. We see this most in south-facing gable windows where the dark bronze anodized finish absorbs afternoon sun. Our fix is a full frame replacement with the updated 3120-TB corner joint, not a caulk patch that fails again in 18 months.
- CWS 5400 Series arched casements: The curved sash rail warps slightly out of plane, causing the multipoint lock to misalign and the weatherstrip to compress unevenly. Homeowners notice it first as a whistle during northeast winter fronts. We re-square the sash in our shop, replace the worn keepers with OEM-spec hardware, and rehang to factory tolerance rather than forcing the lock closed.
- CWS 4100 Series oversized picture units: The insulated glass seal fails prematurely in custom sizes above 60″ x 96″ because the factory desiccant strip is undersized for the airspace volume in our humidity. We replace with a warm-edge spacer system and specify a thicker desiccant bed, which adds cost upfront but eliminates the fogging callbacks.
- CWS geometric corner windows (90-degree and bay configurations): The mullion post settles when the original installer did not shim to the structural header. The result is a visible sag in the sightline and operable sashes that bind. We pull the trim, sister the header if needed, and reinstall with documented plumb readings at three points.
- CWS custom radius top units in stucco openings: The arched frame profile does not always match the radius of the rough opening cut by the builder, leaving a gap that previous contractors filled with expanding foam. We template the opening with a flexible trammel, order to that exact radius, and refuse to install against a foam shim because it compresses and cracks the stucco within two years.
Before
AfterOur CWS Custom & Geometric Windows Process
- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives with a documented measuring protocol for shaped openings. We record rough opening dimensions, radius centers for arches, and sightline clearances at the trim plane. You receive a copy before we leave.
- 2
Written price before any work starts. The quote specifies CWS model line, glazing package, finish, and hardware. It also names the exact dollar amount. Haven Clause 1: the measurement and the quote are the same document.
- 3
Parts decision with evidence. For warranty-active units, we source OEM CWS components. For out-of-warranty geometric units where CWS lead times stretch past 10 weeks, we present a quality aftermarket equivalent with comparable Miami-Dade NOA documentation and let you decide.
- 4
Installation with photo record. Verified crews install per manufacturer spec and our Haven Standard. Every step is photographed: frame shimming, fastener pattern, sealant bead, and final sightline alignment. You receive the photo record at completion.
- 5
Testing and sign-off. Operable units are cycled 10 times. Impact-rated units are inspected for laminate edge exposure. We measure the sightline again and compare it to the survey.
- 6
365-Day Done Right Promise. If the operation, seal, or sightline drifts in the first year, we return and make it right. This is written into the Haven Standard, not offered as a courtesy.

FAQs
No, provided the work is performed to CWS installation specifications and documented with photos and product serial numbers. We follow manufacturer tolerances for frame shimming, fastener spacing, and sealant application, and we record serial numbers for every unit we touch. If your CWS warranty is still active, we source OEM parts and flag any factory defects we find so you can file a claim. Call (786) 481-0414 and we will review your warranty status during the measured survey.
Standard CWS custom shapes run 4-6 weeks from order to delivery; complex radius tops or oversized units often stretch to 8 weeks. We have seen South Miami Heights homeowners lose six weeks to a restocking fee because a competitor measured the rough opening instead of the finished frame. Measure it right the first time, or measure it twice more and still order the wrong size. Our survey protocol prevents that.
Yes, within the limits of anodized aluminum aging. We pull a finish sample and cross-reference against CWS current color charts, then note any variance in writing before you approve the order. For painted finishes, we can send a chip to CWS for custom color match at additional cost, typically $180-$320 per unit.
Replace the insulated glass unit if the frame is sound and the sash is not warped. For CWS 4100 Series oversized units, we replace the IG with a warm-edge spacer and upgraded desiccant, which costs $800-$1,400 versus $2,800+ for full frame replacement. If the sash rail is warped or the corner weld has failed, full replacement is the only fix that lasts. We will show you both options in writing.
Yes, for any job that alters the opening size or changes the egress configuration. For like-for-like replacement in the same footprint, permit requirements vary by Miami-Dade municipality; we verify this during the measured survey and include permit costs in the written quote if required. Every permit we pull includes inspection scheduling and sign-off documentation in your photo record.
