Service area · Ontario, CA
Ontario sits right in the middle of our service area and we work in the city regularly — a mix of newer Ontario Ranch homes in the New Model Colony, mid-century stock near Euclid and Holt, and older bungalows close to the airport that are great remodel candidates.
Ontario homeowners
Ontario's building and safety department has one of the more straightforward permit processes in the Inland Empire. Standard bathroom and kitchen remodels move through quickly; ADUs follow the state's streamlined timeline. For new builds in Ontario Ranch, we work with your HOA on exterior approvals and run interior scope independently.
Many of our Ontario clients are first-time remodelers — they bought newer construction, lived in it for five to ten years, and are ready to change the layout. We spend extra time up front on design because most people underestimate how differently a wall-removal or kitchen reconfiguration changes how the whole house lives.
We're a licensed California general contractor (CSLB #1120021), bonded and insured, drive-time 20 minutes from most Ontario addresses. Whether it's a 1960s ranch in Ontario Ranch, New Model Colony, downtown Euclid Avenue and the Mountain Avenue corridor that needs its first real remodel in forty years, or a newer build where you want to open the kitchen or add an ADU in the backyard — we handle the whole job under one contract.
Full gut-and-replace in Ontario homes — demo, waterproofing, tile, vanities, lighting, done in 3 to 6 weeks.
Cabinets, counters, backsplashes, moved walls and new electrical for the way you actually cook.
Backyard ADUs, garage conversions, second-story additions — permitted through San Bernardino County.
Larger builds, structural work, whole-home renovations — one accountable team start to finish.
