New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Miramar pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
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.

CGI Custom & Geometric Windows in Miramar: What to Know First
We install and service CGI custom and geometric windows in Miramar as an independent CGI service provider, with most measured surveys scheduled within two business days and written quotes delivered before any work begins. Typical custom CGI orders run four to six weeks from survey to installation, depending on glass complexity and frame finish. We do not quote over the phone; Haven Clause 1 requires that the measurement and the price travel on the same document.
This page is for Miramar homeowners who already own CGI windows and need custom shapes, arched replacements, or oversized geometric units, or for owners comparing CGI against other impact-rated lines for a new build or retrofit. Call (754) 260-1468 to schedule your measured survey. The written quote is free, and it is the same document we use for installation.
How CGI Products Fail - and How We Fix Them

- Sentinel by CGI arched top units: The curved aluminum extrusion on early Sentinel series develops stress cracking at the springline where the radius transitions to the jamb. We have replaced seventeen of these in Miramar’s Sunset Lakes area alone. Our fix: we order the replacement arch from CGI with the thermal break intact, then back-seal the joint with silicone structural glazing tape rather than the standard gasket, which buys movement tolerance Miramar’s afternoon heat cycles demand.
- Impact-rated geometric sashes losing argon: CGI’s Estate Collection geometric units use a dual-seal spacer system that can fail at the mitered corners of hexagonal and octagonal shapes. The symptom is interior condensation that wipes clear, not etching. We replace with OEM sash assemblies rather than field-reglazing, because CGI’s corner keys are swaged, not screwed, and breaking that joint voids the impact certification.
- Fixed geometric frames corroding at weep channels: On homes near Miramar Parkway with western exposure, CGI’s standard mill finish weeps clog with salt and road grit. Water backs into the sub-sill and rots the buck. We machine new weep slots at 45 degrees, install stainless mesh screens, and document the frame depth with photos before and after. The customer keeps the photo record.
- Oversized CGI picture units bowing in the center: Custom widths over 72 inches in the Targa series require intermediate support mullions that some original installers omitted to preserve the view. The glass fatigues, the IG unit fails, and the homeowner blames the glass. We measure the live load deflection, specify the correct CGI mullion kit by part number, and show the customer the engineering table before ordering.
- Geometric casement operators stripping: CGI’s roto operators on triangular and trapezoid sashes use a shorter arm throw than standard rectangles. Owners force them past the stop, stripping the nylon gear. We stock the correct 9-inch arm for CGI geometric operators, not the 13-inch rectangle version that some technicians install by default. The wrong arm will operate for three months, then fail.
Before
AfterOur CGI Custom & Geometric Windows Process
- 1
Measured survey. We arrive with a printed copy of CGI’s current spec sheets and measure every rough opening to the sixteenth. The customer keeps the survey. Sonia Raman reviews each geometric shape against CGI’s manufacturing radius limits before we quote.
- 2
Written quote on the same document. Haven Clause 1. The price includes the CGI unit, freight from the Tampa facility, installation, sealant, and disposal. No change orders. The quote is the invoice.
- 3
Parts decision logged. For repairs, we note whether we are specifying OEM CGI components or verified aftermarket equivalents, and why. For custom orders, we confirm the series, finish code, and glass package against the customer’s energy audit if they have one.
- 4
Installation with photo documentation. Every step is photographed: the opening before, the shim placement, the fastener pattern, the sealant bead, and the final operation test. The customer receives the photo record within 24 hours.
- 5
Operational test and sign-off. We operate every moving sash, check the lock engagement with a feeler gauge, and verify the weep paths are clear. The customer signs the completion document, which includes the 365-Day Done Right Promise stamped underneath.
- 6
Cleanup and documentation delivery. We leave the work area broom-clean and deliver the photo record, the warranty document, and the final invoice as one packet. No separate mailings.
What CGI Custom & Geometric Windows Costs in Miramar

These are the price ranges we have written on CGI custom and geometric jobs in Miramar over the past eighteen months. Your measured survey will produce an exact figure.
| Scenario | Typical Range |
|---|---|
| CGI standard rectangle replacement, impact-rated, installed | $890 - $1,340 per opening |
| CGI arched or radius top unit, custom ordered | $1,650 - $2,400 per opening |
| CGI geometric (hexagon, octagon, trapezoid), impact-rated | $1,920 - $2,780 per opening |
| CGI oversized picture unit over 72″ wide with mullion | $2,400 - $3,600 per opening |
| CGI sash replacement in existing geometric frame | $680 - $1,120 per sash |
| CGI operator or hardware repair, geometric casement | $240 - $380 |
What moves the price: the glass package (clear, Low-E, or laminated impact), the frame finish (mill, anodized, or Kynar paint), the need for crane access on oversized units, and whether the original buck is square within our tolerance. We do not discover these variables at installation; we document them at survey and the price does not move.

Why Miramar Homeowners Call Sightline Windows & Doors Miramar for CGI Work
We are independently owned and operated under the Haven Standard, not a franchise, and we have installed or repaired CGI products in Miramar since 2012. Our technicians carry license numbers on their uniforms; Haven Clause 3 requires that the person at your door matches the person on the record. We also specify PGT, CWS, ES Windows, and ECO Window Systems when the opening or the budget calls for a different performance tier, so our CGI recommendation is not driven by inventory.
The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. If the sash binds after six months because Miramar’s humidity swelled the buck, we return and correct it. The photo record from your installation becomes the evidence for that correction. Measure it right the first time. Everything else follows from that.
FAQs

No. CGI’s limited warranty covers defects in materials and workmanship for the original purchaser, regardless of who installs or services the unit, provided the work does not alter the frame or glass package in ways the manufacturer does not permit. We document every parts decision and installation method to preserve that coverage. For questions about your specific CGI warranty status, call us at (754) 260-1468 with your serial numbers.
Sometimes. CGI maintains archived extrusion dies and finish codes for ten years on most residential lines. For older units, we cross-reference the original order code against current stock and can often source a compatible match from CGI’s commercial division or specify a verified aftermarket finish that meets AAMA 2605. We will not guess; we will show you the sample against your existing frame before ordering.
Repair the sash if the frame is square, the thermal break is intact, and the IG unit failure is isolated to one lite. Replace the full unit if the frame has corrosion at the weep, the corner keys are loose, or the geometric shape has shifted out of plumb. We make this recommendation at survey and put the reason in writing. Call (754) 260-1468 for a free second opinion on any written estimate you have received.
Four to six weeks from signed quote to delivery at our Miramar warehouse, plus one to three days for installation scheduling. Geometric shapes require CNC cutting of the aluminum extrusion at CGI’s Tampa facility, and impact-rated glass packages add a lamination step that standard clear glass does not. We do not quote expedited delivery because CGI does not offer it; anyone who promises faster is substituting a different product.
Yes, when the replacement alters the opening size, the product rating, or the egress compliance. Miramar requires a building permit for impact-rated window installations in the wind-borne debris region, and we pull that permit as part of our scope. The permit, the inspection, and the final approval are documented in your photo record. The permit cost is listed as a line item in your written quote, not added later.
