New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Cutler Bay 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 Cutler Bay Owner’s Guide
CGI window installation in Cutler Bay typically runs $340-$780 per opening depending on series, size, and whether the existing frame is square and dry. We stock CGI-compatible installation hardware for the Estate, Sentinel, and Targa series on our Cutler Bay trucks, and most replacements are surveyed and started same-week. Homeowners usually discover an installation problem when they feel drafts along the sash, see daylight between frame and wall, or notice the window has shifted in its opening after a storm season.
Which CGI Models This Applies To
CGI organizes its residential line into three series, and each handles installation differently. The Estate Series uses a heavier extruded frame that demands shimming at six points minimum; the Sentinel Series is lighter but uses a proprietary fastening pattern that standard hurricane clips do not match. The Targa Series, CGI’s impact-rated premium line, requires structural silicone bedding and specific backer rod diameters that differ from PGT’s comparable product.
To identify your series, check the etched marking on the glass spacer bar or the AAMA label inside the frame head. The model prefix tells us everything: ES- for Estate, SE- for Sentinel, TA- for Targa. We do not guess. We cross-reference that prefix against CGI’s 2019-2024 installation manuals, which we keep in digital form on every Cutler Bay survey tablet.
On OEM versus aftermarket: CGI’s own installation clips and shims are available, but we also source Florida-tested equivalents from C.R. Laurence and Tamlyn that meet Miami-Dade NOA standards. For Targa Series jobs, we use OEM structural silicone exclusively. For Estate and Sentinel, the aftermarket hardware performs identically at lower part cost, and we document which we used in your photo record.

Before
AfterSigns Your CGI Window Installation Is Failing
- Draft along the sill or jamb. This usually means the original foam backer rod has compressed or the sealant bead has separated from the frame. In Cutler Bay’s salt-air environment, we see this accelerate after four to six years, sooner if the original installer skipped the primer.
- Visible gap between frame and interior drywall. The window has shifted in its rough opening, often because the original fasteners missed the structural stud or were under-torqued. This is common in Lakes by the Bay homes built during the 2015-2018 construction wave, where speed sometimes beat square.
- Condensation inside the glass unit, not on it. The insulated glass seal has failed, but the root cause is frequently installation-related: frame racking during original put-in stressed the edge seal. We check for this during our measured survey.
- Window binds or scrapes when operated. The sash is no longer plumb in its track. On CGI’s sliding windows, this traces to sill deflection or head sag from inadequate shimming at the center span.
- Water staining on the interior sill after rain. The exterior sealant has failed at the head or the weep holes are blocked. Cutler Bay’s driving summer rains find every gap; we clear and verify weep function on every replacement.
Replacement Cost & What’s Included
| Component | Cutler Bay Price Range |
|---|---|
| CGI-compatible installation hardware set (Estate/Sentinel) | $85-$140 |
| CGI OEM installation hardware set (Targa) | $160-$220 |
| Structural silicone and backer rod, per opening | $45-$75 |
| Labor: removal, reframe prep, reinstall, seal | $210-$445 |
| Total installed, typical single opening | $340-$780 |
What drives the range: frame condition (aluminum corrosion adds prep time), accessibility (second-story openings require our pump-jack setup), and whether the rough opening needs reframing. We quote the full scope in writing before any work starts. The price on your measured survey is the price on your invoice. Every CGI installation in Cutler Bay carries our 365-Day Done Right Promise under the Haven Standard, and you receive the documented photo record before we leave.
DIY or Call Us?
There is safe checking, and there is unsafe work. A homeowner can verify the model label, photograph any visible gaps, and confirm whether the window still operates smoothly. What we do not recommend: removing a CGI impact-rated unit from its opening without proper support bracing, or attempting to reseal with consumer-grade caulk that does not meet Miami-Dade adhesion standards. A CGI Targa Series window weighs 85-120 pounds depending on dimension; the frame can torque quickly if unsupported, damaging the glass or the rough opening.
If the opening isn’t square, no amount of caulk makes it right. We have reframed openings in Cutler Bay where previous DIY or handyman work concealed the problem with trim. The Haven Standard requires we document the rough opening with photos before the new unit goes in, so you see what we saw.
Call (786) 886-1945 to schedule your free measured survey. We will bring the CGI hardware that matches your series and give you the written price before any work starts.
FAQs
Twelve to eighteen years for the installation itself, though the salt-air exposure in South Miami-Dade can shorten sealant life to eight years if the original installer skipped surface prep. We use primed substrates and backer rod on every reinstall to push toward the longer end of that range. Call (786) 886-1945 for an exact quote on your specific CGI model.
Sometimes, if the frame is square and the failure is limited to sealant or hardware. We have resealed Estate Series windows in Cutler Bay that needed only clip replacement and fresh silicone. If the frame has shifted or the rough opening is compromised, partial repair is false economy. We will tell you which category yours falls into during the free survey.
Most single openings are completed in three to five hours, including removal, rough-opening inspection, reinstallation, and sealant cure time before we operate the sash. Multi-opening jobs or Targa Series units with structural silicone requirements may extend to a full day. We schedule arrival times, not vague windows, under Haven Clause 2.
We carry CGI-compatible installation hardware for Estate, Sentinel, and Targa series, plus Miami-Dade-approved sealants and fasteners matched to each. For specialized glazing stops or custom jamb extensions, we order against your measured survey and arrive with the exact part. We do not improvise with “close enough.”
