What Our Clients Say about us..
"I connected with Steven Moreno at Ridgeline Western Construction about a year ago when I was scoping out a project. Steven’s knowledge blew me away from framing, additions, new construction, materials, etc. He broke everything down like it was nothing & in a way that I actually could understand. The company is based out of Fontana and covers a huge range from San Bernardino and Riverside all the way through Los Angeles and Orange County. So if you’re in that area and need a general contractor that you can rely on then I would highly recommend Ridgeline Western Construction to get the job done right."
