CGI Energy-Efficient Windows in Boca Raton: What to Know First
CGI energy-efficient window service in Boca Raton typically runs $180 to $1,400 depending on whether we’re replacing failed insulated glass, swapping in Low-E panels, or doing a full-frame replacement, and most single-unit jobs are completed in one visit. As an independent CGI service provider, we diagnose and repair the exact window you have, not a guess from a call center. This page is for Boca Raton homeowners whose CGI windows are fogged, drafty, or failing to block Florida heat the way they did when new. Call (561) 816-5648 and a live person answers, day or night.
How CGI Products Fail - and How We Fix Them
CGI builds a solid impact window. We’ve installed and serviced enough of them across Boca Raton to know exactly where they wear down over time, especially in our salt air and afternoon thunderstorm cycles. Here’s what we see most often:
- Fogged or hazy glass on CGI Estate and CGI Sentinel series: The insulated glass unit seal fails, letting humid Florida air in between the panes. The Low-E coating starts to look cloudy and the window loses thermal performance. We replace the IG unit with an ENERGY STAR-rated panel matched to your frame, not a cheap single-pane workaround.
- Frame gasket compression on older CGI Tribute 1000 units: After years of direct sun on west-facing walls in neighborhoods like Boca Square or Millpond, the gaskets stiffen and shrink. That’s the draft you feel at the sill. We pull the old gasket, clean the channel, and install a new compression gasket that restores the air seal without replacing the whole sash.
- Argon gas loss on dual-pane CGI windows: Argon leaks out over time through the seal, and once it’s gone, the window’s insulation value drops roughly 30 to 40 percent. You can’t see it, but your electric bill shows it. We test the unit, confirm gas loss, and replace the IG panel with fresh argon-filled Low-E glass.
- UV damage to interior finishes near CGI clear-glass windows: Flooring, upholstery, and wood trim along Federal Highway and Mizner Park condos fade fast when windows lack UV-blocking coatings. We upgrade the glass to insulated laminated with a UV-blocking interlayer that cuts fade-causing rays while keeping impact rating intact.
- Sticky or swollen sashes on CGI windows after hurricane-season humidity: Aluminum frames hold up well, but older weatherstripping can trap moisture and bind the sash. We rebalance the sash, replace the weatherstripping, and lube with a dry silicone so the window opens clean for those first cool fronts in November.
Our CGI Energy-Efficient Windows Process
Here’s what happens when you call us for a CGI energy-efficiency job in Boca Raton, from the first phone call to the final walkthrough:
- 1
You call (561) 816-5648. A live person answers and schedules a visit. No voicemail loop. No “we’ll get back to you within two business days.”
- 2
We inspect every window in question. We check glass condition, seal integrity, frame alignment, and measure for any energy-performance gaps. Ed’s background in building construction technology means we look at the whole opening, not just the glass.
- 3
We give you an upfront, line-item quote. You’ll see exactly what we’re replacing, what parts cost, and what labor costs. No change orders mid-job. If we find something unexpected, we stop and explain it before touching another screw.
- 4
Parts decision: OEM or proven aftermarket. For glass units, we source quality ENERGY STAR-rated IG panels that fit your CGI frame precisely. For hardware, we use OEM components when it matters for warranty and tested aftermarket parts when they outperform the original.
- 5
Install and seal. We set the new glass, replace gaskets and weatherstripping, and run an air-infiltration check to make sure the unit is actually sealed. The job isn’t done when the window looks right; it’s done when it tests right.
- 6
You walk the job with us. We show you what we did, what we tested, and why it’s right. Then the 36500-Day Done Right Promise kicks in: if it’s not done right, we come back and make it right.
What CGI Energy-Efficient Windows Cost in Boca Raton
Straight numbers, because you deserve them. Here’s what we charge for common CGI energy-efficiency work in Boca Raton:
- Single IG glass replacement (Low-E, argon-filled): $340-$720 per window, depending on size and series
- Full sash replacement with ENERGY STAR glass: $680-$1,150 per sash
- Weatherstripping and gasket replacement (per window): $95-$210

- UV-blocking laminated glass upgrade: $1,050-$1,400 per window, depending on frame size and access
What moves the price: whether we’re replacing just the glass or the whole sash, the size of the unit (larger fixed panels cost more than smaller operable windows), and whether the frame needs rework. Every estimate is free, and the price we quote is the price you pay. Call (561) 816-5648 to schedule a free estimate, and if you have a written estimate from another company, bring it in for a free second opinion.

We also service PGT, CWS, ES Windows, and ECO Window Systems, so if your home has a mix of brands, one call covers it all.
FAQs
In most cases, we can replace just the insulated glass unit and keep your existing CGI frame. That’s true for CGI Estate, Sentinel, and Tribute lines. Full replacement only makes sense when the frame is corroded, racked, or no longer square. Call (561) 816-5648 for an exact assessment, and the estimate is free.
It depends on which warranty you have and what we’re doing. Glass replacement on an out-of-warranty unit doesn’t affect anything, and for in-warranty windows we help you understand what the manufacturer covers before we touch anything. We’re transparent about what we can and can’t warranty as an independent CGI service provider.
The clear signs are fogged glass, a draft you can feel at the frame edge, or a room that’s noticeably warmer than the rest of the house in the afternoon. Argon loss is invisible but real. We offer a $150 window energy audit that finds the actual problem and credits that fee toward any repair or replacement work we do.
Call (561) 816-5648 and we’ll get you scheduled quickly, often same week. We’re a local company with a published address in the area, not a national chain routing you to some regional dispatcher. For urgent storm-related failures, we prioritize getting eyes on your windows fast.
