CGI Construction in Highland, CA | Polaris Contractors
We provide independent CGI in San Bernardino County and across Highland, CA: frameless shower enclosures, stainless sinks, faucet hardware, and mirrored bath fixtures, serviced and installed by a full-scope general contractor. The one thing that makes our CGI work here different is that we read every installation through the lens of Highland’s foothill fire-risk detailing and expansive clay soils. Call (855) 473-6535 for a free estimate on any CGI product in your Highland home.
Why Highland Residents Choose Us for CGI Service
CGI builds a solid product. But a frameless shower door or an undermount kitchen sink only performs as well as the person who hangs it. We’ve been remodeling homes across the Inland Empire’s fire-prone foothills long enough to know that a spec sheet is the starting point, not the finish line. Torque values, clearance gaps, material compatibility: we sweat those details so your enclosure stays square and your sink stays sealed.
We’re an independent contractor, which matters more than people realize. We buy CGI directly, we warranty our own installs, and we have no affiliation with or authorization from CGI. That means we’re free to tell you the truth: repair the rollers, or replace the whole door. Rick Sondermann, our owner, built his career on being the contractor neighbors recommend to neighbors. His father was a finish carpenter who believed in doing things once and doing them right, and that philosophy still drives every CGI job we take in Highland. CGI sales & service are available throughout our Highland coverage area.

Common CGI Construction Problems We Solve in Highland
- Frameless shower door rollers that flatten and bind. Highland’s hard water is tough on top-rail rollers. They wear flat, the door sags, and it starts dragging against the jamb. We see this on CGI Concept Series doors all the time, usually within three to five years of install.
- Vinyl sweeps and doorstop bumpers that dry-crack and yellow. The dry, intense heat and UV through west-facing glass in Highland bake those soft parts stiff. Once a sweep cracks, the door loses its seal and water creeps under the threshold.
- Undermount sink clips and silicone seals failing at the rim. Summer heat cycling plus mineral-heavy water corrodes the seal around CGI undermount sinks. Water seeps along the rim and drips into the cabinet base. By the time you notice the water stain, the cabinet is often already damaged.
- Faucet cartridges stiffening and brushed finishes pitting. Highland’s water is hard on faucet internals. Cartridges get stiff, handles stick, and brushed nickel or chrome finishes pit faster than they would down in Anaheim or Cypress.
- Improperly shimmed shower enclosures in homes with slab movement. Highland sits on expansive clay. Slabs shift with the seasons, and a frameless glass enclosure that was never properly shimmed starts pulling at its anchor points. Glass doesn’t flex. Something fails, and it’s usually the mounting hardware or the level of the door.
CGI Service in Highland: What Local Conditions Mean for Your Equipment
Here’s a checkable fact about Highland that most contractors never connect to your bathroom or kitchen: the homes along Highland’s foothill edge toward CGI in Redlands and the San Bernardino National Forest routinely trip Chapter 7A ignition-resistant requirements when a roof or siding project pulls a permit. So any CGI shower or bath remodel that touches a foothill wall, vent, or roof penetration gets detailed to ember-resistant standards that flatland contractors skip. And there’s a second layer that affects your CGI hardware directly: Highland’s expansive clay soils swell and shrink with seasonal moisture, cracking slabs and shifting walls. A frameless glass door that was square on day one can be pinched by day 700. When a foothill-edge remodel off the streets rising toward the national forest came to us with a sagging CGI sliding enclosure, we found flattened top-rail rollers and a vinyl sweep baked stiff in the west-facing sun. Our tech re-hung the door on OEM rollers, replaced the sweep and doorstop bumpers, re-caulked the track, and because the job sat in the fire-risk zone, flagged the exterior wall penetration for Chapter 7A detailing before closing it up. The enclosure now glides and seals like new, and the reinspection passed without a correction. That’s the difference between reading a manual and understanding Highland.
CGI Models & Products We Service in Highland
We service the CGI Concept Series frameless sliding shower doors and standard hinged enclosures, undermount and drop-in stainless steel kitchen sinks, kitchen and bath faucet lines, frameless glass shower enclosures, and mirrored bath hardware. Our parts approach is simple: OEM CGI replacement rollers, sweeps, cartridges, and clips for anything under warranty or load-bearing. High-quality aftermarket glass hardware only where it matches the original hole pattern and meets the same rated capacity. If your enclosure frame is sound but the rollers and seals are gone, we re-hang it. We’ll tell you to replace it only when the glass, track, or frame is actually compromised.

FAQs – CGI Construction in Highland
Repair it. In most Highland homes, the issue is flattened top-rail rollers and a worn vinyl sweep, not the glass or frame. We re-hang the door on OEM rollers, replace the sweep and bumpers, and re-level the track. You’re looking at a few hundred dollars instead of a few thousand. Replacement only makes sense if the glass is cracked, the track is bent, or the frame is corroded beyond re-shimming. Call (855) 473-6535 and we’ll tell you which one you’re looking at.
Yes, and we do it often. A CGI frameless enclosure that’s structurally sound can stay in place while we re-tile, replace the vanity, update the plumbing, and refinish the walls. We protect the glass, service the rollers and seals while we’re in there, and re-hang it square when the room settles. You save thousands by not replacing a door that still has years left.
No. We’re an independent general contractor. We buy CGI products directly, install them to manufacturer specification, and warranty our own work. We’re not affiliated with or authorized by CGI, and that’s deliberate: we’d rather tell you when a repair makes sense than when a replacement pads a sales quota.
OEM CGI replacement rollers, sweeps, cartridges, and clips for anything under warranty or load-bearing. Aftermarket hardware only when it matches the original hole pattern and rated capacity. Never a mismatched roller on a glass door that someone’s kid slams shut daily.
A walk-in shower installation in Highland typically runs $4,500 to $12,000 depending on size, glass configuration, and whether we’re doing tile work around it. The material matters, but so does the substrate: slab movement from expansive clay means some Highland homes need extra floor prep before tile goes down.
