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 Impact Garage Doors: The Olympia Heights Owner’s Guide
CGI impact garage doors in Olympia Heights typically run $2,800-$4,600 installed for a standard single-car opening, with most replacements quoted and scheduled within 48 hours. We stock CGI-compatible track hardware, rollers, and torsion spring assemblies for the Estate and Estate Collection series, and we carry the full line of impact-rated panels through our eight verified manufacturer partnerships. Most Olympia Heights owners discover a problem when the door hangs at an angle, shudders in the track, or won’t hold during a pressure test after a named storm.
Which CGI Models This Applies To

CGI markets impact garage doors under the Estate and Estate Collection names, with model identifiers stamped on a metal tag inside the top track channel. The Estate 200 and Estate 300 series use 2-inch track spacing with nylon-encased steel rollers; the Estate 500 upgrades to 3-inch heavy-gauge track and sealed bearing rollers rated for higher cycle counts. We also see the occasional Estate 700 in Olympia Heights, typically on homes built 2018-2022 near the Bird Road corridor where wind-borne debris requirements stepped up.
Here’s the compatibility gotcha: CGI changed roller stem diameter from 7/16 inch to 1/2 inch in 2019. A 2017 Estate 200 door with original hardware will not accept current OEM rollers without bushing adaptation, and most aftermarket suppliers don’t flag this. We stock both stem sizes and the brass reducer bushings, because we’ve measured enough retrofits in Olympia Heights to know the mix.
OEM parts carry the CGI part number and match factory tolerances exactly. Quality aftermarket equivalents from Clopay and Amarr meet the same wind-load ratings and often beat OEM lead time by two to three weeks. For a door under warranty, we quote OEM first. For out-of-warranty units, we present both options with the spec sheet side by side. Sightline Windows & Doors Olympia Heights is an independent service provider, not affiliated with CGI.
Before
AfterSigns Your CGI Impact Garage Door Is Failing
- The door drifts closed or won’t stay open halfway. This points to torsion spring fatigue or a failed cable drum. CGI’s springs are rated for 10,000 cycles, but South Florida’s salt air and summer humidity cut that by 20-30 percent in our experience. We measure spring tension with a calibrated winding bar; anything below spec gets replaced in matched pairs.
- Loud grinding or metal-on-metal screech during operation. Usually a seized roller bearing or a bent track section. The Estate series rollers have a sealed grease cavity that dries out after five to six years near the coast. We replace with sealed-bearing rollers rated for 50,000 cycles and lube the track with silicone, not WD-40, which attracts grit.
- Visible gap between door panel and weather seal, or light showing through. The bottom rubber astragal has hardened or the side seals have pulled from their retainers. CGI uses a proprietary bulb-style seal on Estate 500 and 700 doors; generic D-seal won’t seat properly and leaks air and water.
- Door reverses immediately after touching the floor or won’t close fully. Travel limit switches need recalibration, or the safety sensors have shifted. In Olympia Heights, we find this often after a minor impact or after homeowners store pool equipment too close to the sensor beam.
- Panel dents, delamination, or impact-rated glass fracture. CGI’s impact panels are aluminum-skin over polyurethane core; once the skin is compromised, the panel loses its Miami-Dade NOA rating. We document the damage with photos for insurance and quote panel replacement or full door replacement depending on age and parts availability.
Replacement Cost & What’s Included

| Component | Price Range (Installed) | Notes |
|---|---|---|
| Single torsion spring (pair) | $340-$520 | Includes calibrated winding, safety cables, lube |
| Roller set (10 rollers, full door) | $180-$280 | OEM or sealed-bearing equivalent |
| Bottom seal / astragal | $140-$220 | CGI profile or verified equivalent |
| Track section (bent/damaged) | $260-$400 | Includes alignment and fastener replacement |
| Full door replacement, single car | $2,800-$4,600 | Impact-rated, permit, haul-away included |
| Full door replacement, double car | $4,200-$6,800 | Varies with insulation and window insert options |
What drives the range: door size, insulation upgrade, window insert configuration, and whether the existing opener integrates cleanly with new panel weight. Every quote we write in Olympia Heights starts with a measured survey you keep. The price on that document matches the final invoice. Haven Clause 1.
Our 365-Day Done Right Promise covers the installation and hardware. If a spring goes soft or a roller seizes inside twelve months, we replace it and document the cause. No charge. No argument.
DIY or Call Us?
There’s a safe middle ground and a hard stop. Homeowners can inspect the door for visible damage, test the auto-reverse with a 2×4, and clear debris from the track. These checks cost nothing and tell us plenty when you call.
The hard stop is torsion spring work. CGI impact doors use paired high-tension springs above the header, wound to balance 150-250 pounds of door weight. A slipped winding bar or misjudged tension release can cause serious injury. We’ve reworked three DIY spring jobs in Olympia Heights in the past two years; in two cases, the homeowner bent the track trying to force the door manually. Measure it right the first time. Everything after that is just paperwork.
Call (786) 400-2761. We’ll schedule a free estimate, bring the right parts for your CGI model, and show you the written price before any work starts.
FAQs

Typically 7-10 years in South Florida’s climate, compared to the 10,000-cycle factory rating. Salt air and humidity accelerate corrosion fatigue. We replace springs in matched pairs and include a written cycle count at installation. Call (786) 400-2761 for an exact quote - estimates are free.
Minor dents in non-structural areas can sometimes be filled and repainted without affecting the wind-load rating, but any breach of the aluminum skin or delamination of the core requires panel replacement to maintain the Miami-Dade NOA. We document the damage and present both options with the code requirement in writing. Call (786) 400-2761 for an exact quote - estimates are free.
Most single-car installations finish in one day, assuming the rough opening is sound and permits are pre-cleared. Double-car doors or jobs requiring structural header reinforcement may extend to a second day. We pull permits, schedule inspection, and pass before we invoice. Call (786) 400-2761 for an exact quote - estimates are free.
We carry rollers, springs, cables, drums, and seals for the Estate 200 through 700 series on every Olympia Heights service vehicle. Full panels and door sections are warehouse-stocked in Miami-Dade with next-day delivery to our shop. If we don’t have it, we tell you before we schedule, not after we arrive.
