CGI Construction in Muscoy, CA | Pinecrest Contractors
We provide independent CGI cabinet, countertop, metal roofing, and glass shower installation and repair across Muscoy. The thing that makes our CGI work here different is simple: Muscoy is unincorporated San Bernardino County, which means nearly every job we do sits under County Building & Safety review, and a surprising number of those jobs uncover unpermitted prior work that needs legalizing before we can finish. Call (855) 702-1622 for a free estimate on CGI work in Muscoy.

Why Muscoy Residents Choose Us for CGI Service
Gil Rourke, our owner, learned construction the slow way: Palomar College’s construction technology program, then years on residential and light commercial builds across the Temecula Valley before Pinecrest Contractors came together. He still keeps a worn framing square from his framing brother hanging in his truck cab. That background matters when you’re asking us to put CGI cabinets into a room addition a previous owner framed out in the 1980s without insulation.
You’ll find a lot of CGI sales & service contractors who can order product. Fewer know what happens to that product inside Muscoy’s older housing stock when the slab is out of level or the roof is skip-sheathed. We do. The right material in the right place, that’s where the job starts.

Common CGI Construction Problems We Solve in Muscoy
- Warped and delaminating cabinet boxes in owner-built additions. A good portion of Muscoy’s room conversions were built without permits and without proper insulation or ventilation. That traps heat and moisture, and CGI plywood boxes and face frames are not immune to it. We see delamination at the joints and doors that will not close square by midsummer.
- Quartz countertops cracked at seams or overhangs. CGI engineered stone does not flex. When the underlying cabinets sit on a slab that has settled, or on floor framing that is an inch out of level, the seam becomes the weak point. Muscoy’s older ranch homes and mobile homes settle, and the cracks follow.
- Standing seam metal roof panels backing out screws. CGI 24-gauge standing seam is a strong roof, but Muscoy gets real Santa Ana wind uplift and the thermal swing from 40-degree winter nights to 110-degree summer afternoons. Panels expand and contract, and fasteners over skip sheathing without proper underlayment will work loose over time.
- Frameless glass shower enclosures leaking at hinges. CGI 3/8″ tempered glass enclosures look sharp, but they depend on tight seals and proper wall prep. In Muscoy bathrooms with original windows and no exhaust fan, humidity sits on the hinges and seals, and mineral buildup from the hard water does the rest.
- Counters and cabinets installed over unpermitted slab additions. We have lost count of how many Muscoy kitchens sit on concrete that was poured without permits. The floor slopes, the cabinet run slopes with it, and the countertop either cracks or the drawers bind. Fixing the cabinet install often means fixing the floor first.
CGI Service in Muscoy: What Local Conditions Mean for Your Equipment
Muscoy is not a city. It is an unincorporated San Bernardino County community, and that single fact shapes every CGI installation and repair we do here more than any other variable. When a homeowner adds a garage or a room in Muscoy, the county controls the permit, not a city hall. And because much of the housing stock is older, self-built, or owner-improved, a routine CGI cabinet or shower install often triggers a County Building & Safety review that uncovers unpermitted previous work. That previous work has to be legalized before we can finalize the job. On a ranch-style home off California Street, we installed CGI semi-custom cabinets and a quartz countertop, only to find the kitchen floor out of level by over an inch due to an unpermitted slab addition. We leveled the substrate, secured the cabinets, and worked with the homeowner to pull the necessary county permits, turning a potential callback into a fully compliant remodel. That is the difference between a contractor who knows Muscoy and one who just knows CGI product. For the full picture on how we work in this area, see our Muscoy service area page.
CGI Models & Products We Service in Muscoy
We work with CGI semi-custom kitchen cabinets, including their plywood box construction and dovetail drawer joinery. We install and repair CGI quartz countertops across a range of colors and edge profiles, and we offer CGI repair in Rialto. We handle CGI standing seam metal roofing panels in 24-gauge steel, and we service CGI frameless glass shower enclosures built from 3/8″ tempered glass.
On parts, we take a straight line. For cabinet hardware and glass shower hinges, we use CGI OEM replacement parts so the fit and finish hold. For roofing fasteners and underlayment, we specify aftermarket components rated for high heat and wind, because Muscoy’s conditions demand them. We will also tell you honestly when a repair is not worth it, especially on standing seam roofs over 15 years old. Replacement pricing is a better long-term conversation than chasing a panel that keeps backing out.

AfterCGI Service Pricing in Muscoy
Pricing depends on what you are putting CGI product into. An owner-built addition with an unlevel slab costs more than a clean, code-compliant kitchen, because we have to correct the substrate before the cabinets go in. A CGI glass shower in a bathroom with no ventilation may need framing and waterproofing work behind the wall before the glass can hang level. Here is what the three most common CGI projects run in Muscoy:
| CGI Project | Typical Range |
|---|---|
| Full Kitchen Remodeling (CGI cabinets + quartz) | $14,000 – $45,000 |
| Walk-In Shower Installation (CGI frameless glass) | $4,500 – $12,000 |
| Standing Seam Metal Roof (CGI 24-gauge) | $15,000 – $40,000 |
Every estimate is free and line-itemed. Call (855) 702-1622 for an exact quote on your CGI project in Muscoy.

FAQs – CGI Construction in Muscoy
Yes, in most cases. Because Muscoy is unincorporated, any structural or built-in work, including cabinet installation in a kitchen or bathroom, falls under San Bernardino County Building & Safety. If the existing room was never permitted, the county may require legalization of that prior work before the final inspection on your cabinet project. We handle the permit pull and coordinate the reviews for you.
Quartz is dimensionally stable in heat, but the cabinets underneath are not. Muscoy’s summer heat and the wide overnight temperature swing cause wood framing to expand and contract, and if your cabinets were installed on an unlevel slab, the countertop bears the stress at seams and overhangs. Proper leveling before installation is the prevention. Call (855) 702-1622 to have us check your existing cabinet run before you order stone.
CGI standing seam metal roofs installed correctly over proper underlayment will typically last 40 to 50 years, even with Muscoy’s UV exposure and Santa Ana wind. The lifespan collapses, sometimes to 15 or 20 years, when the panels are screwed over skip sheathing without underlayment and the fasteners back out. Most of the metal roof problems we see in Muscoy are installation failures, not product failures — the same issue we find when providing CGI repair in Highland.
Yes, and this is a regular part of our work in Muscoy. When you are adding a walk-in shower to a bathroom that sits inside an unpermitted addition, the county will not sign off on the shower until the addition is brought into compliance. We coordinate the as-built documentation, the corrections, and the County Building & Safety review so the shower install is not held up. Call (855) 702-1622 for a free estimate that includes the legalization scope.
CGI semi-custom cabinets use plywood boxes and dovetail drawers, which hold up better in Muscoy’s heat than particleboard boxes from big-box lines. Their engineered quartz counters resist staining and UV fading better than laminate. Their standing seam roofing panels, when installed correctly, are wind-rated for the Santa Ana conditions we get here. You are paying for materials that tolerate the Inland Empire climate, which matters on an unincorporated lot where maintenance is entirely on you, whether you’re in Muscoy or need CGI in Loma Linda.
