New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors North Miami 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 North Miami: What to Know First
As an independent CGI service provider, we measure, order, and install CGI custom and geometric windows across North Miami with written pricing delivered before any work begins. Most custom CGI units run $1,400 to $3,800 installed depending on glazing specification and shape complexity, with lead times typically 4 to 7 weeks for impact-rated geometric shapes. This page is for North Miami homeowners who already own CGI products and need arched, curved, or oversized custom units replaced or upgraded, or who are comparing CGI against other impact lines for a new geometric opening. Call (786) 706-0468 to schedule your free measured survey. The quote you receive is the document we work from, not an estimate that shifts later.
How CGI Products Fail - and How We Fix Them
- Series 375 fixed geometric units with seal decompression in gable ends. The thermal break in CGI’s Series 375 fixed custom shapes can separate at the radius corners after 6 to 10 years of North Miami’s wet-season expansion cycles. We see this most often in Keystone Point and Sans Souci homes where the original install didn’t allow for drainage weep alignment with the slope. Our fix: remove the sash, document the thermal break separation with photos, and specify a replacement unit with factory-ordered corner keys rather than field-mitered joints. The new unit gets installed with sill pan flashing tied to the WRB, not caulked over.
- Series 401 impact casement with operator arm binding on trapezoid conversions. When a rectangular Series 401 casement gets field-converted to a trapezoid or eyebrow shape, the operator arm geometry often doesn’t match the new hinge axis. The sash drags at the lock side and the multipoint won’t engage. We measure the original hinge axis, order a CGI-compatible heavy-duty operator with the correct offset, and shim the frame to maintain the designed sightline. This is cheaper than replacing the entire window, but only if the frame extrusion isn’t twisted.
- Custom radius top units with fogging between panes on east-facing elevations. CGI’s custom curved IGUs use a flexible spacer at the radius that can fatigue faster than straight-line units under morning sun load. In North Miami, east faces get hammered from 7 a.m. to noon nine months of the year. We specify warm-edge spacer upgrades for replacement radius units and verify the desiccant fill rate with the supplier. The alternative is a full IGU replacement every 5 to 7 years, which we’ve documented on multiple Biscayne Boulevard corridor properties.
- Oversized CGI fixed picture units with sill track deflection above 60 inches wide. CGI’s standard sill extrusion for fixed custom shapes doesn’t include intermediate support legs at widths beyond 60 inches. In North Miami’s 170 mph wind zone, that span can deflect enough to stress the glazing edge bite. We add fabricated aluminum sill supports tied to the rough opening framing, documented in the photo record, and specify laminated glass with a heavier interlayer rather than monolithic tempered for spans over 72 inches.
- Series 240 sliding geometric units with roller corrosion in coastal zip codes. The stainless roller housing in CGI’s Series 240 custom sliders holds up well, but the axle pin can crevice-corrode within 3 miles of salt water. North Miami’s 33181 and 33162 zip codes see this regularly. We replace with marine-grade 316 stainless rollers, not the standard 304, and document the old roller condition in the photo record. If the sill track is already worn from the wobble, we mill a replacement track insert rather than replacing the entire frame.
Before
AfterOur CGI Custom & Geometric Windows Process
- 1
Measured survey with documented rough opening. We arrive with the measured survey form you keep. Every dimension is taken twice, diagonals checked for square, and existing frame condition photographed. Sonia Raman trained in building construction technology at Miami Dade College, where she picked up the habit of checking every rough opening twice before touching a shim. That habit hasn’t changed.
- 2
CGI series identification and failure diagnosis. We locate the original order code or extrusion profile to confirm the series, then identify whether the issue is unit failure, install failure, or both. The diagnosis goes in writing.
- 3
Parts decision: OEM CGI, verified compatible, or full unit replacement. For geometric shapes, OEM is often the only warranty-safe path. We name the supplier, the lead time, and the exact part number in the written scope. If a compatible aftermarket component meets the Haven Standard for evidence and traceability, we document why.
- 4
Installation with real-time photo record. Every step is photographed: old unit removal, rough opening condition, flashing details, new unit set and shimmed, final lock and operator test. You receive the photo record within 24 hours.
- 5
Final test and 365-Day Done Right Promise activation. We operate every moving part, check the sightline alignment, and verify the weep paths are clear. The Haven Standard Clause 5 applies: No surprises. If it’s not done right, we make it right. The written warranty and photo record are your documentation.

FAQs
No, provided the work uses OEM or manufacturer-compatible parts and follows CGI’s installation guidelines. We document every part number and installation detail so your warranty record stays clean. For custom geometric units, OEM parts are typically the only path that preserves coverage. Call (786) 706-0468 and we’ll review your specific CGI warranty terms at no charge.
Standard lead time is 4 to 7 weeks for impact-rated custom shapes from CGI’s Florida facility. Complex radius units with warm-edge spacer upgrades or oversized laminated glass can extend to 8 weeks. We quote the lead time in writing with your price so you can plan around it. Call (786) 706-0468 to check current CGI production schedules.
If the IGU seal has failed and fogging is between the panes, the insulated glass unit must be replaced. For custom geometric shapes, that usually means ordering a new IGU from CGI or a verified fabricator to the exact radius and sightline dimensions. Frame damage or seal decompression may require full unit replacement. We diagnose which path applies during our free survey. Call (786) 706-0468 to schedule.
No. Haven Clause 1 states that the measurement and the quote are the same document. The only circumstance where the price changes is if we discover concealed damage during removal, such as rotted rough opening framing or corroded structural supports. If that occurs, we photograph the condition, stop work, and present a revised written scope before continuing. No surprises. Call (786) 706-0468 for your written quote.
Yes, for all impact-rated window replacements and any job involving structural modification to the opening. We pull the permit, schedule the inspection, and pass it. The permit number goes in your documentation packet along with the photo record and warranty. North Miami Building Department requires product approval documentation for impact-rated units, which we submit with the permit application. Call (786) 706-0468 and we’ll confirm permit requirements for your specific job.
