CGI Construction in Pomona, CA | Timberline Contractors
We’re Timberline Contractors, and we provide independent CGI construction services across Pomona. That means full kitchen and bath remodels, roof repair and replacement, and structural work using CGI stucco, drywall, roofing, and masonry products. What makes our CGI work different here is simple: we’ve spent years on Pomona’s split housing stock, from pier-and-beam bungalows near Lincoln Park to slab tract homes off the 10 and 60. Call (866) 253-5808 for a free estimate.
Now, one thing up front. We are not authorized, sponsored, or endorsed by CGI. We’re an independent contractor who knows CGI products inside and out and installs them properly on Pomona homes. If you want a crew that understands both the material and the ground it’s going onto, we’re the ones to call.
Why Pomona Residents Choose Us for CGI Service
Pomona sits at the east end of Los Angeles County where the San Gabriel Valley meets the Inland Empire. That location gives the city a construction market with a split personality: century-old craftsman and Spanish Colonial bungalows near downtown and Lincoln Park needing seismic retrofit and foundation work, plus 1960s-80s tract infill and warehouse conversions feeding off the 10 and 60 freeway corridors. A Pomona contractor has to be equally fluent in historic plaster-and-lath rehab and Code-compliant remodel work, and that’s the range we work in every week.
Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College before spending years on Eastside bungalow remodels and mid-size commercial builds across the LA basin. He’s the guy who will actually explain why your stucco substrate choice matters more than the finish on top of it. We’ve carried that approach into every CGI project we take on in Pomona’s 91767, 91768, 91769, and 91797 zip codes.

Common CGI Construction Problems We Solve in Pomona
CGI products are solid, but Pomona’s climate and housing stock create specific failure patterns. Here’s what we see most often:
- Stucco and plaster finish cracking on older bungalows. Pomona’s dry-summer/wet-winter cycle moves the expansive clay soils beneath raised pier-and-beam foundations. Hairline cracks in CGI three-coat stucco widen into water intrusion paths around windows and at foundation transitions. We repair the substrate first, then match the finish.
- Undersized electrical panels in 1900s-1940s stock. Original knob-and-tube-era wiring and 60-amp panels trip or fail when modern kitchen and bath loads are added. We bring the panel and circuits up to Code before any new CGI cabinet or fixture installation gets energized.
- Asphalt shingle and underlayment degradation on east- and south-side tract homes. Intense summer heat and Santa Ana wind uplift lift tabs, strip granules, and compromise the CGI roof underlayment. Winter rain finds the gaps.
- Galvanized and early copper plumbing corrosion in post-war and 1970s slab homes. New vanity, shower, and kitchen layouts often uncover supply and drain problems behind the wall. We address those before finishes go in.
- Foundation settlement before framing or cabinets can go in. In Pomona’s older bungalow neighborhoods, original pier-and-beam supports have settled or rotted after decades of cycling. Any CGI kitchen or bath remodel usually starts with re-leveling.
CGI Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing that makes Pomona different from every neighboring city we work in. Those older bungalow neighborhoods between Garey Avenue and Lincoln Park sit on raised pier-and-beam foundations. After decades of dry-summer/wet-winter cycling in the valley-floor clay, those original piers settle, rot, or shift. So when we’re called in for a CGI kitchen remodel on a 1920s Spanish Colonial near Lincoln Park, the first step isn’t cabinets or countertops. It’s re-leveling the subfloor, sistering framing, and making sure the structure underneath can actually carry the new load. Neighboring cities like CGI in La Verne with mostly slab tract housing rarely hit that first step. If a Pomona contractor quotes you a CGI kitchen remodel without mentioning the foundation, that should worry you.
We learned this the hard way, repeatedly. On one 1920s Spanish Colonial bungalow near Lincoln Park, our crew opened up a kitchen wall and found the original pier-and-beam supports had settled and rotted. We re-leveled the subfloor and sistered framing before setting the new CGI cabinet boxes and quartz tops. We also caught knob-and-tube-era wiring feeding the old kitchen circuit and had the panel and circuit brought up to Code so the new appliances and under-cabinet lighting could be energized safely. That’s Pomona work. You don’t get that on a generic CGI repair in Montclair page.
CGI Models & Products We Service in Pomona
We work with the full range of CGI construction products on Pomona homes. That includes CGI exterior stucco and plaster finish systems (three-coat and one-coat), CGI drywall and gypsum board products, CGI metal and tile roofing underlayment components, and CGI masonry and hardscape/paver products. On the parts side, we spec OEM or equal-quality CGI components and finish systems matched to the original assembly. Correct stucco base and mesh for older plaster-and-lath walls. Proper underlayment for tile and metal roofing. We don’t substitute the cheapest available material. We also tell owners honestly when a targeted repair will outlast the building’s other systems and when full replacement is the better investment. If you need CGI sales & service, we’re the crew to talk to.

FAQs – CGI Construction in Pomona
Because many of Pomona’s older bungalows near Lincoln Park and downtown sit on raised pier-and-beam foundations that have settled or rotted after decades of dry-summer/wet-winter cycling. Before we can set CGI cabinet boxes or countertops, we have to make sure the subfloor is level and the framing is sound. Neighboring cities with mostly slab tract housing, like those needing CGI service in Claremont, don’t hit this step. Call (866) 253-5808 and we’ll assess yours before quoting.
Yes. We match the original CGI stucco or plaster finish assembly, including base coats and texture, so new work blends with the surrounding wall. Matching finish on a 1920s Spanish Colonial takes more care than a modern tract home, but it’s doable. We spec OEM or equal-quality CGI components to keep the assembly consistent.
Both, usually. Pomona’s summer heat strips granules and breaks down the adhesive bond on asphalt shingles, then Santa Ana winds lift the tabs that have already loosened. Once the CGI underlayment is exposed, winter rain leaks follow. We inspect the underlayment condition and tell you whether a targeted repair will hold or full replacement is a better investment. Call (866) 253-5808 for a roof evaluation.
Yes. We’ve seen enough galvanized and early copper plumbing in post-war and 1970s slab homes to know that a new vanity or walk-in shower often uncovers supply and drain problems behind the wall. Same with undersized panels and knob-and-tube-era wiring in the older stock. We bring both systems up to Code before finishes go in. That’s part of why our quotes include a thorough wall-open inspection.
Yes, we handle ADU construction and garage conversions in Pomona. CGI product choice does matter here. The stucco system, roof underlayment, and drywall you spec affect how the structure handles Pomona’s intense summer heat, Santa Ana wind, and expansive clay soils. We’ll walk you through the options.
