Some of our Services
Ridgeline Western Construction is committed to client satisfaction.

House Framing
House framing is the skeleton that bears every load and shapes the final look and utility of your Rancho Santa Margarita building. Ridgeline Western Construction fields a framing specialist on every job so nothing slips from engineering to site. We plan every beam, stud, and panel for structural loads and mechanical systems, set hardware to be visible for inspection, and keep sequencing dialed so framers and future trades meet a ready-to-build structure. At sign-off, you have a frame set for the rest of the trades—not a maze of retrofits and cut corners.

Home Additions
A home addition in Rancho Santa Margarita is more than extra square footage—it is a structural project managed from planning through final sign-off. Ridgeline Western Construction oversees every step, including structural design, permits, framing, inspections, and finishes. The full addition, from framing to final walkthrough, runs under one contract and is managed as a unified project, not a set of piecemeal trades. We self-perform the critical framing and schedule every licensed subcontractor, so you get a code-compliant addition with clear permit history.

New Home Construction
New home construction by Ridgeline Western Construction covers every step from building plans to final walkthrough, all managed under a single contract. In Rancho Santa Margarita, we coordinate engineering, permitting, framing, licensed trades, and project supervision for a ground-up build you can document start to finish. The owner remains hands-on from site prep to certificate of occupancy.

Home Remodeling
Remodeling a home in Rancho Santa Margarita is more than a surface update—it’s about making structure, layout, and systems work as a whole. Ridgeline Western Construction manages the entire process, from verifying structural needs to scheduling every licensed trade and ensuring permit, inspection, and finish are all handled under one project plan. The site is managed step by step, not just covered with new materials.

Roof Replacement
Roof replacement in Rancho Santa Margarita means taking worn, damaged, or leaky roofing down to the deck and rebuilding with new materials. Ridgeline Western Construction manages everything from the initial inspection, material choices, and full tear-off to expert installation and city permit sign-off. We coordinate all licensed roofing work, keep documentation clear, and remove all debris as part of the job. You deal with one point of contact for a finished roof built to code in Rancho Santa Margarita.

Commercial Remodeling
Commercial remodeling updates offices, retail, and workspaces in Rancho Santa Margarita to fit current needs—new layouts, finishes, and systems included. Ridgeline Western Construction plans the scope, manages all framing and layout changes, and schedules every licensed subcontractor under one contract. From owner walkthrough to city inspections, every phase is handled, so your project works for your business and passes code in Orange.

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."
