Why Pomona Residents Choose Us for CGI Service
We’ve been working in Pomona since before the Arts Colony started filling with coffee shops. Grant Rowan grew up watching relatives frame and pour their way through weekend projects in Los Angeles, then trained at Los Angeles Trade-Technical College before founding this company in 2007. That background matters here because Pomona’s housing stock doesn’t forgive guesswork.
We know CGI products inside and out - the Aspire and Prelude cabinet series, the Calacatta and Carrara quartz lines, the Timberline HDZ and Landmark roofing systems. We’re not authorized by CGI, and we don’t pretend to be. What we are is a licensed general contractor that has completed hundreds of CGI installations across Pomona’s pre-1940s Craftsman bungalows and post-WWII worker cottages alike. We source OEM CGI parts when they make sense, but we’re also comfortable specifying aftermarket hinges, drawer slides, and heat-rated roofing components that hold up better in Pomona’s 105-110°F summers.
Every quote is flat, written, and delivered before anyone picks up a tool. Under Clause 1 of the Haven Standard, that’s non-negotiable. Measure twice, then we can talk.
Common CGI Construction Problems We Solve in Pomona
- Cabinet warping and joint separation in historic homes. CGI cabinets installed in Pomona’s pre-1940s Craftsman bungalows - especially around Lincoln Park and the historic downtown core - often fail at the joints because original single-pane windows create wild indoor humidity swings. Our crew uses reinforced plywood boxes and specialized blocking to keep doors square when the plaster moves.
- Quartz countertop cracks near sink cutouts. In Pomona’s 1940s-1960s slab-on-grade worker cottages, unlevel or flexing substrates are the rule, not the exception. CGI Calacatta and Carrara quartz countertops crack at the sink when the base shifts. We level with self-leveling compound and add proper support blocking before setting stone.
- Premature roofing granule loss from inland heat. CGI Timberline HDZ and Landmark shingles on Pomona homes lose granules and turn brittle up to 30% faster than identical installations in coastal LA. The combination of intense UV, 105-110°F peak temperatures, and poor attic ventilation in older homes cooks the asphalt. We specify heat-rated underlayment and upgrade ventilation as standard practice here.
- Shower seal failure from hard water scaling. Pomona’s municipal water supply runs hard with calcium and magnesium. CGI shower pans and enclosures accumulate mineral deposits that degrade rubber seals and trap moisture behind tile. We inspect seal condition during every bathroom project and recommend proper water conditioning when scaling is advanced.
- Foundation movement throwing off level installations. Pomona’s expansive clay soils shift seasonally, particularly in the older neighborhoods east of the Fairplex corridor. CGI cabinetry and countertops installed without accounting for this movement end up racked and binding within a year. We assess slab and pier conditions before quoting and build in adjustment tolerance.

AfterCGI Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona’s historic Lincoln Park neighborhood contains a high concentration of pre-1940s Craftsman bungalows with original wood lath and plaster walls, which complicates CGI cabinet and countertop installations because standard anchoring methods often fail. You can’t drive a cabinet screw into 90-year-old plaster and expect it to hold 200 pounds of dishes. Our crew uses specialized blocking and plaster-friendly fasteners to ensure secure, lasting fits. This isn’t a technique we learned from a manual - it’s field knowledge developed across dozens of Pomona historic-home renovations where the walls literally flex differently than modern drywall. The same clay soils that crack foundations here also transmit vibration through the structure, so we add isolation pads and flexible caulking at cabinet backsplashes to prevent joint separation. Contractors working out of Ontario or Rancho Cucamonga, where the housing stock is decades newer and the soil conditions differ, rarely encounter this specific challenge. We do, regularly, and we’ve built our CGI installation protocols around it.
CGI Models & Products We Service in Pomona
We work with the full CGI residential line: CGI sales & service covers the Aspire and Prelude cabinet series with plywood box construction and soft-close hardware; the Quartz and Granite countertop collections including Calacatta and Carrara styles; the Timberline HDZ and Landmark asphalt shingle roofing systems; and the full bath fixture line including vanities and shower enclosures.
For repairs, we stock common CGI hardware locally - hinges, drawer slides, seal kits - so Pomona customers aren’t waiting two weeks for a cross-country shipment. When OEM parts are back-ordered or discontinued, we source aftermarket equivalents that meet or exceed original specs. In this climate, we often recommend upgrading to corrosion-resistant or heat-rated components regardless. The small premium pays back in service life.

FAQs - CGI Construction in Pomona
Yes. We’ve completed numerous CGI installations in Pomona’s historic districts, including Lincoln Park and the downtown core, where pre-1940s construction requires specialized anchoring and blocking techniques. Our crew is experienced with City of Pomona historic preservation requirements and state URM compliance where applicable. Call (626) 606-1081 to discuss your specific property.
CGI Timberline HDZ and Landmark shingles deteriorate up to 30% faster in Pomona’s inland heat pocket than in coastal LA due to UV exposure and 105-110°F peak temperatures. We mitigate this with heat-rated underlayment, improved attic ventilation, and proper ridge venting. For a roof assessment specific to your Pomona home, call (626) 606-1081.
Yes, but we assess slab levelness and structural integrity first. Many 1940s-1960s Pomona worker cottages have settling or inadequate reinforcement that causes substrate flexing. We level with self-leveling compound and add support blocking before installing CGI Aspire or Prelude cabinets and quartz countertops. Schedule a free evaluation at (626) 606-1081.
A full CGI bathroom remodel in Pomona ranges from $9,000 to $28,000, with small bathrooms starting at $5,000.

Call (626) 606-1081 for an exact number - estimates are free.
Yes. We pull all required City of Pomona building permits and coordinate inspections for CGI roofing installations. For properties in the Second Street historic corridor or adjacent URM districts, we navigate the dual-track permitting process involving both city and state requirements simultaneously.
