CGI Construction in Garden Grove, CA
We’re Garden Grove General Contractors, and we provide independent CGI sales, service, and installation across Garden Grove, CA. The short answer: we handle CGI shower enclosures, tub-to-shower conversions, and mirror or closet glass systems in the exact housing stock Garden Grove was built on. What makes our work here different is simple: we’ve spent years inside 1950s tract homes and 1970s stucco apartments, so we know how CGI glass actually fails when it’s bolted to these walls. Call us at (877) 373-9230 for a straight answer on your shower glass.

Why Garden Grove Residents Choose Us for CGI Service
Most our home remodeling crews can hang a panel. Few can tell you why your CGI enclosure is leaking into the wall cavity behind a 1961 bathroom. Noel Cardenas grew up in the West Grove neighborhood of Garden Grove, a few blocks from the Gem Theater, and never left. He learned construction fundamentals at Santiago Canyon College in Orange, then spent years working residential and commercial builds across the greater Garden Grove area before founding this company. That background matters when the job isn’t just glass, it’s framing, drain relocation, and waterproofing behind the glass. We use OEM CGI hinges, rollers, seals, and bumpers on any unit still in warranty or under ten years old. When a part has been discontinued, we spec a quality aftermarket replacement and tell you why. We don’t guess at what’s in the wall. We open it, look, and fix what’s actually failing. That’s the difference between a glass crew and a general contractor who happens to know CGI products inside and out.
We’re an independent CGI service provider. Not affiliated with, authorized by, or endorsed by the manufacturer. We sell the brand on its merits, not on a badge. If a CGI product is the right call for your bathroom, we’ll say so. If a different enclosure will hold up better in your specific house, we’ll say that too. That honesty is why Garden Grove homeowners keep our number. For full details on the brand and what we carry, see our CGI service page.

Common CGI Construction Problems We Solve in Garden Grove
- Water tracking behind framed enclosures on 1950s tile walls. Original mid-century framing shifts over decades. When a framed CGI shower enclosure is installed against those older tile walls, the seal breaks and water follows the frame into the wood behind the stucco. We pull the frame, assess the rot, re-frame if needed, and re-hang with proper waterproofing.
- Sliding door tracks seized with hard water and soap scum. Garden Grove’s water is hard. Bottom tracks on CGI sliding systems pack with mineral buildup, the rollers chew through themselves, and the door starts dragging long before the glass fails. We clean, replace rollers and seals, and adjust the track so it rolls clean.
- Semi-frameless panels pulling loose at hinge points. This one’s common in 1970s and 1980s stucco apartment bathrooms. The wall cavity isn’t what the hardware spec assumes. Anchors set into old drywall or thin-set over plaster give way, and the hinge pulls. We sister in blocking behind the wall and re-set the hardware into something that holds.
- Tempered glass chipping at edges from settled floors. Older slab-on-grade bathrooms in Garden Grove settle. When the floor drops a quarter inch, the enclosure is no longer square. Worn bumpers and misaligned seals let the glass catch, and edges chip. We re-square the enclosure, replace the seals and bumpers, and the glass is usually fine.
- Failing seals on tub-to-shower conversions. Many CGI conversions in Garden Grove were installed over original tub alcoves that were never properly waterproofed. When the seal fails, water gets under the enclosure and into the subfloor. We re-seal, and where the waterproofing never existed, we fix that too.
CGI Service in Garden Grove: What Local Conditions Mean for Your Project
Here’s the thing most shower glass companies won’t tell you. Garden Grove’s 1950s and 1960s single-story tracts were built with narrow hall bathrooms and standard 5-foot tubs. When a homeowner wants that tub gone and a walk-in shower in its place, the glass is the easy part. The real work is re-framing the wall and moving the drain. And because so many of these original Garden Grove homes still run clay sewer lines that are prone to root intrusion and collapse, we scope every drain relocation around a sewer inspection before we ever set a CGI enclosure. Skip that step and you can end up with a beautiful new shower draining into a collapsed line that backs up into the house. That’s not a shower problem. It’s a Garden Grove problem. Our full-scope contracting background means we handle the framing, the drain, the inspection, and the glass under one contract. For everything else we do across the city, see our Garden Grove service area page.
CGI Models & Products We Service in Garden Grove
We service the full Cypress CGI service lineup: Ready-Fit framed and frameless shower enclosures, Series 300 sliding and swinging shower door systems, custom-frame and semi-frameless tub-to-shower glass conversions, and CGI mirror and closet or wardrobe glass systems. For repair work, we keep a local stock of OEM rollers, hinges, seals, and bumpers for the most common CGI models in Garden Grove. That means most hardware failures get fixed in one visit. Glass rarely needs replacing on its own. Most CGI calls we run are hardware-and-seal jobs, and we’ll tell you honestly when a re-hang and reseal will outlast the enclosure versus when a full replacement is the smarter spend.

AfterCGI Service Pricing in Garden Grove
CGI shower work in Garden Grove prices by scope, not by guess. A hardware repair runs well under a full replacement. A tub-to-shower conversion that requires moving a drain and re-framing an out-of-square alcove costs more than a simple panel swap. Here’s what we quote in this market:
| Service | Price Range |
|---|---|
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Bathroom Remodel | $9,000 – $28,000 |
Every estimate is free, written, and line-itemed. No change orders unless you change the scope. If you’re weighing repair versus replacement, call (877) 373-9230 and we’ll give you a real number after we see the enclosure.

FAQs – CGI Construction in Garden Grove
Sometimes, yes. If the original alcove is square, the framing is sound, and the drain works, a CGI frameless enclosure can go in over new backer and waterproofing without tearing out the whole bathroom. If the alcove is out of square or there’s water damage behind the old tile, you’ll need re-framing before the glass goes up. We can tell you which you have in one visit. Call (877) 373-9230 for a free estimate.
In Garden Grove, if your house still runs original clay sewer lines, yes. Moving a drain is a code-triggering change, and the city’s older lines fail regularly. The inspection costs a few hundred dollars and tells you whether the line will handle the new drain location before you spend thousands on glass. Call (877) 373-9230 and we’ll scope it into the quote.
Garden Grove’s hard water is the usual culprit. Mineral deposits build up in the bottom track, the rollers bind, and they wear out fast. We replace them with OEM rollers and adjust the track, but if your water hardness is extreme, we may recommend a squeegee habit or a water softener to extend roller life. Either way, the fix is under an hour and far cheaper than new glass.
Cheaper to fix the hinge. The glass is almost never the problem. When a hinge pulls loose, the failure is the anchor behind the wall, not the glass panel. We open the wall, add blocking, reset the hinge, and the enclosure works again. Replacement only makes sense if the glass is chipped, cracked, or the frame is corroded beyond saving. We’ll show you the damage and let you decide.
Rain doesn’t stop a shower install, but it can expose problems the dry season hides. Older slab-on-grade homes with poor drainage can shift slightly during sustained winter rains, and a fresh enclosure set on a moving floor can rack and lose its seal. We check drainage and grading around the foundation before installing, and we schedule heavy waterproofing work for dry stretches when possible. Call (877) 373-9230 to talk through your specific situation.
