Serving Fullerton, CA and surrounding areas. (657) 354-1477
Custom Fullerton Sunrooms was founded in 2017 with one straightforward goal - give homeowners in Fullerton and northern Orange County a sunroom contractor they could actually trust. At the time, the market was full of national franchise operations and here-today-gone-tomorrow crews. We built this business to be neither of those things.
Fullerton is a city of established neighborhoods. Craftsman bungalows near downtown, postwar ranch homes on the east side, newer construction further north. We have worked on all of them. We understand how older homes are put together, what permits the city requires, and which materials hold up under Southern California's heat and seasonal Santa Ana winds.
Every project starts with a free on-site estimate and ends with a final walkthrough. In between, we keep homeowners informed and on schedule. That approach has kept our clients coming back - and sending their neighbors our way - for years. We are proud to still be a local, owner-operated business serving the same community we started in.
