CGI Bathroom Remodeling Nationwide

CGI Bathroom Remodeling: The Campbell Owner’s Guide

CGI bathroom remodeling in Campbell typically runs $9,000-$28,000 for a full renovation, with CGI’s modular wet-room systems and precision-fit shower enclosures being a specialty we’ve installed across the South Bay since 2007. We stock CGI-compatible hardware, waterproofing membranes, and custom glass channels on our Campbell-area trucks, and we can usually inspect and quote within 48 hours. Most homeowners first realize something’s wrong when the frameless glass door starts binding, the channel weep holes clog with hard water scale, or the silicone bond between CGI’s anodized aluminum track and the tile substrate begins to separate.

Which CGI Models This Applies To

CGI’s bathroom product line breaks into three series that matter for replacement and retrofit work. The Serenity Series uses a 3/8-inch heavy-glass frameless design with a bottom U-channel in brushed nickel or oil-rubbed bronze; the Estate Series steps up to 1/2-inch glass with a more substantial wall jamb and header system. The Builder Series, common in Campbell tract homes built between 2015 and 2022, uses a semi-frameless design with thinner glass and a simpler sweep assembly. To identify yours, check the etched CGI logo in the lower corner of the glass and measure the glass thickness with a caliper or ruler. The channel depth varies: Serenity takes a 1-inch channel, Estate 1-1/4 inch. We source OEM CGI tracks and seals through their San Jose distribution partner, though for discontinued Builder Series hardware we often machine-match equivalent anodized aluminum from CRL or Dulles Glass. The decision between OEM and quality aftermarket comes down to warranty alignment - CGI honors their 10-year glass warranty only when OEM hardware is used, which we document on every replacement.

Signs Your CGI Bathroom Remodeling Is Failing

• Glass door drags or catches at the bottom. The nylon sweep or bottom guide has worn flat, or the U-channel has collected enough Campbell hard water scale to narrow the clearance. Left alone, this stresses the hinge pivot and can crack the glass.
• Water pools outside the shower after every use. The flexible vinyl sweep has stiffened - common in bathrooms with poor ventilation, which we see often in older Campbell ranch homes with original exhaust fans. The sweep loses its seal against the threshold and water follows the track outward.
• Visible mold or soft drywall near the channel ends. CGI’s weep holes, designed to drain channel water back into the shower pan, have clogged with mineral deposits or caulk. Water backs up and migrates behind the tile.
• Hinge screws loosen repeatedly after tightening. The wood or metal stud behind the hinge plate has stripped or the CGI backplate has fatigued. This is a wall-structure issue, not a screw issue - continuing to tighten risks glass fracture.
• Anodized finish on the channel looks chalky or spotted. The protective layer has degraded, usually from aggressive cleaning products or the chlorine-heavy water supply in parts of Campbell served by the San Jose Water Company. Once the anodizing fails, the aluminum oxidizes and swells, binding the glass.

Replacement Cost & What’s Included

What drives the range: glass thickness, whether the wall substrate needs repair after channel removal, and whether we’re matching existing tile or installing new. Every quote from Rowan Construction Group Campbell is a flat written price with line-item parts and labor - no “call for pricing,” no open-ended allowances. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Our 365-Day Done Right Promise covers the installation, and CGI’s OEM hardware carries their own 10-year warranty when we document the serial numbers, which we do as standard.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can replace a CGI sweep or clean weep holes with a pick and white vinegar - that’s maintenance, not repair. But once you’re unbolting a 70-pound glass panel from a fatigued hinge plate, the risk profile changes fast. Tempered glass doesn’t crack; it explodes into granules when the edge takes a stress point wrong. We’ve had two Campbell calls this year where a homeowner removed a panel successfully, then set it on a towel with a pebble underneath - $1,800 mistake. If you’re seeing wall softness, hinge looseness, or any glass edge chip, that’s where we come in. We bring suction cups, padded stands, and the practiced hand that comes from having done this a few hundred times. Call (831) 704-1211 and we’ll schedule a free inspection with a written quote before any work starts.
