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.

How CGI Products Fail - and How We Fix Them

- Sentinel by CGI single hung sashes drop or tilt unexpectedly. The tilt-latch mechanism wears where the plastic cam meets the metal balance shoe, especially in Miramar homes with west-facing elevations that cycle through rapid humidity swings from Lake Lucerne’s open water. We replace with OEM-spec tilt latches or upgraded metal-cam assemblies where the frame jamb allows it, then test the balance tension against CGI’s published sash weight chart.
- Impact-rated horizontal rollers develop hard rolling or frame binding. The stainless steel tandem roller trucks on Estate Series units collect salt and grit from Miramar’s limestone-dust environment, and the adjustment screw heads strip when homeowners try to compensate. We pull the sash, clean the track with a dry lubricant-compatible solvent, install replacement trucks with sealed bearings, and reset the frame square to within 1/16 inch so the sash rolls without dragging.
- Sentinel double hung upper sashes lose their seal or fog between panes. The warm-edge spacer system in units manufactured 2015-2019 had a higher-than-expected failure rate in South Florida’s UV load, particularly where dark exterior frames sat in direct afternoon sun. We measure the insulated glass unit (IGU) to the sixteenth, order a replacement through our glazing supplier with the same impact certification label, and install it without disturbing the frame’s Miami-Dade NOA compliance.
- Impact door multipoint locks throw out of alignment. CGI’s entry door systems rely on a master deadbolt and two to four shootbolts; when the composite door slab swells in Miramar’s wet season, the bolts miss their keepers and the handle set binds. We diagnose with the door under its own weight, then adjust or replace the multipoint gearbox and relocate keepers rather than forcing the lock to meet a warped frame.
- Vinyl impact window frame corners separate or weep. CGI’s vinyl line uses heat-welded corners that can stress-crack if the original install left the frame fastened too tight against Miramar’s concrete block, preventing thermal expansion. We cut the fasteners, shim to allow movement, and weld or epoxy the corner depending on crack depth, then reflash to the block with backer rod and sealant that meets the original NOA detail.
Before
AfterOur CGI Impact Windows & Doors Process
- 1
Measured survey. Sonia Raman or a background-checked, uniformed technician arrives with license number provided in advance, measures the opening, records frame type and series, and documents existing damage with photos you receive.
- 2
Written scope and price. We specify OEM or quality aftermarket parts by part number, name the labor hours, and stamp the total. This document is yours to keep. The price on it is the price on the invoice.
- 3
Parts procurement. For CGI repairs, we source OEM hardware through our glazing supplier network or specify aftermarket equivalents where the original part is obsolete and the replacement meets the same load rating. We never substitute without writing it into the scope.
- 4
Installation and testing. We install to the measured survey, not to “close enough.” Impact units receive a post-installation operability test, seal verification, and photo documentation of the completed work.
- 5
Documentation and guarantee. You receive the photo record, the final invoice matching the written scope, and the 365-Day Done Right Promise stamped under Haven Clause 5: No Surprises. If it’s not done right, we make it right.

Why Miramar Homeowners Call Sightline Windows & Doors Miramar for CGI Work
We are an independent CGI service provider, not a factory-authorized dealer, which means we work on the product without obligation to sell you a full replacement when a repair will do. Our technicians carry PGT, CWS, ES Windows, and ECO Window Systems catalogs on their tablets, so if your CGI line is discontinued or a different manufacturer’s frame fits your opening’s performance requirements better, we can specify it without margin pressure.
The Haven Standard governs every job: written price before work (Clause 1), arrival windows kept (Clause 2), verified crews with license numbers (Clause 3), photo evidence on every visit (Clause 4), and no invoice surprises (Clause 5). Sonia Raman grew up in Miami, spent two decades measuring openings across South Florida, and her crew has retrofitted homes backing up to Lake Lucerne City Park where west elevations take the full brunt of open-water wind load. Measure it right the first time. Everything else follows from that.
FAQs

CGI’s warranty covers defects in materials and workmanship for the original purchaser; independent service does not automatically void it, but warranty claims for the original defect must go through CGI directly. We document our parts sources and installation methods so you have a record if a warranty question arises. Call (754) 260-1468 if you need help interpreting your warranty documents.
Common Sentinel and Estate Series hardware ships within 3-5 business days from our glazing supplier; obsolete CGI parts may require 10-14 days for aftermarket equivalent sourcing. We tell you the lead time in the written scope before you approve the job, not after we’ve started. Call (754) 260-1468 for current availability on your specific series.
Repair when the frame is square, the impact rating is current, and the IGU or hardware failure is isolated; replace when the frame has corner separation, the NOA is expired, or the cost of repairs exceeds 60% of replacement. We will tell you which category your opening falls into during the measured survey. Call (754) 260-1468 for a free assessment.
CGI’s standard vinyl colors, white and almond, match across production years; custom painted aluminum frames require a color chip or offcut for matching. We carry a spectrophotometer for field color reading and source touch-up or replacement frames to within acceptable variance. Call (754) 260-1468 to schedule a color match.
Every technician is background-checked, uniformed, and identified by license number before arrival under Haven Clause 3. You will receive a photo and license number by text when your appointment is confirmed. No one enters your Miramar home without that verification. Call (754) 260-1468 if you have any concern about technician identity.
