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 Window Installation: The Miramar Owner’s Guide
CGI window installation in Miramar typically runs $340-$780 per opening depending on series, size, and whether the existing frame is preserved or replaced. We stock CGI frame components, sash hardware, and impact-rated glazing bead for same-day starts on most Series 375, 3750, and Estate Collection units. Most Miramar homeowners discover a problem when they feel Gulf Stream humidity seeping through a cracked glazing bead or when a sash won’t lock flush after a summer storm.
Measure it right the first time. Everything else follows from that.
Which CGI Models This Applies To
CGI’s product line breaks into three tiers we see regularly in Miramar: the Series 375 (non-impact vinyl), Series 3750 (impact-rated vinyl), and the aluminum Estate Collection (impact-rated, often specified in Miramar’s newer construction west of Palm Avenue). The label is stamped on the hinge side of the sash or etched into the spacer bar of the insulated glass unit; if the label’s sun-faded, measure the frame depth and check the glazing stop profile. Series 375 uses a snap-in vinyl bead, 3750 uses a rigid impact bead with integral fin seal, and Estate aluminum uses a screw-applied aluminum stop with EPDM gasket.
We carry OEM CGI glazing bead and hardware, plus verified aftermarket equivalents from Amesbury and Truth Hardware where the spec matches. For impact-rated units, we do not substitute non-OEM glazing components; the Miami-Dade NOA (Notice of Acceptance) is voided by unapproved parts, and Miramar’s building department will flag it on resale inspection.
Before
AfterSigns Your CGI Window Installation Is Failing
- Visible moisture between glass panes. The dual-seal system on CGI’s insulated units has failed, and the desiccant in the spacer bar is saturated. In Miramar, we see this accelerate on west-facing elevations where afternoon heat builds against the glass; once fog appears, the unit’s U-factor is compromised and the glass must be replaced, not defogged.
- Sash drags or binds in the frame. The balance shoe or sash cam has worn, or the frame has settled out of square. CGI vinyl frames flex less than generic vinyl, but Miramar’s limestone substrate shifts seasonally; we check plumb with a 6-foot level before ordering parts, because a new balance in a twisted frame fails in months.
- Lock tongue won’t engage or pops loose. The keeper is misaligned or the lock mechanism has cracked at the zinc die-cast body. Series 3750 multi-point locks are particularly sensitive to frame racking; we measure keeper-to-lock clearance at three points before specifying the replacement.
- Glazing bead pulling away from the frame. UV and salt air harden the vinyl bead, and the barbed legs lose grip. On Lake Lucerne City Park homes we’ve serviced, the west elevation beads degrade 30-40% faster than leeward sides; we note exposure in our measured survey.
- Air infiltration at the sash meeting rail. The fin seal or pile weatherstrip has compressed past recovery. CGI’s original fin seal is a specific durometer; generic replacement strip often over-compresses and loses seal within two seasons.
Replacement Cost & What’s Included
| Service | Typical Range in Miramar |
|---|---|
| CGI insulated glass unit replacement (up to 40″ × 60″) | $340-$520 |
| CGI sash balance / hardware replacement | $180-$290 |
| CGI multi-point lock set (Series 3750) | $220-$340 |
| Glazing bead replacement per sash | $95-$160 |
| Full frame-out replacement, CGI Series 3750 | $580-$780 |
What drives the range: unit size, whether the existing frame is preserved (retrofit) or removed (full frame), and whether the opening requires stucco or drywall repair afterward. Every quote is itemized: glass or part, labor, disposal, and any finish work. The written price you receive is the invoice price; Haven Clause 1, Have it in writing, means no change orders once work starts. The 365-Day Done Right Promise covers the installation and components; glass units carry the manufacturer’s warranty against seal failure, typically 10-20 years depending on CGI series.
DIY or Call Us?
What you can safely check: verify the series from the sash label, confirm the symptom is consistent (not seasonal swelling), and photograph the hardware location for reference. What goes wrong with DIY on CGI windows: impact-rated glazing bead requires a nylon setting block and specific insertion angle; pried in flat, it tears the fin seal and the unit won’t pass a water test. Multi-point locks need sequential adjustment; done out of order, the cam throws misalign and the mechanism binds permanently.

FAQs
CGI vinyl frames typically perform 20-25 years in South Florida, though glazing seal life runs 10-15 years on unshaded west elevations due to thermal cycling. We inspect units we’ve installed at year 5 and year 10 as part of our service record; call (754) 260-1468 for an exact quote on condition assessment.
Fogged or cracked insulated glass cannot be repaired; the seal is factory-set and the desiccant is not serviceable. Single-pane impact glass with surface scratches can sometimes be polished if not in the sightline, but we document the result before you commit. Call (754) 260-1468 for an exact quote; estimates are free.
A standard retrofit replacement takes 2-3 hours per opening; full frame-out with stucco repair runs 4-6 hours. We schedule one opening or a full home, and Haven Clause 2, Arrive on schedule, means the crew is there when specified. Call (754) 260-1468 to schedule your free estimate.
We stock Series 375 and 3750 glazing bead, common sash balances, and multi-point lock components; Estate Collection hardware is ordered to series and finish, typically 3-5 business days. For emergency board-up or security concerns, we carry temporary glazing materials on every truck. Call (754) 260-1468 to confirm availability for your model.
