Remodeling Company in South Pasadena, CA
Hiring a remodeling company in South Pasadena means finding a contractor who understands the city’s older housing stock and strict preservation standards. Our South Pasadena clients typically face three recurring realities: homes built between 1900 and 1940 with lathe-and-plaster walls, permit requirements tied to the city’s cultural heritage status, and foundation settling on the sloping lots above Mission Street. Mason Remodeling handles all three without drama. Call (803) 680-2547 to talk through your project.
Why South Pasadena Homes Are Different

South Pasadena is one of the few cities in Los Angeles County where the majority of residential properties predate World War II, which changes how every remodel gets approached. You cannot simply open a wall and assume standard stud spacing, because many homes on streets like Diamond Avenue and Lyndon Street were framed before modern codes existed. Plaster walls run an inch thick in some 1920s Craftsman bungalows, and you will find knob-and-tube wiring or cast iron drain lines more often than most homeowners expect. That is not a problem if the contractor plans for it and carries it in the written price, which is exactly how we work.
The city’s slopes also matter. Homes in the hills above Monterey Road sit on pads that have shifted over 80 or 90 years, so floor leveling before tile install is common. South Pasadena’s permitting process requires historical review for any exterior change visible from the street on a designated property, which means roof replacement, window changes, even exterior paint color can add review time. A contractor who has not pulled permits here will learn the hard way. We pull permits on every project that requires one, and we include the fee in the written estimate before work begins.
Styles & brands we work with







Our Main South Pasadena Services
South Pasadena homeowners call on us most often for three things: general contracting that keeps an older house structurally sound, bathrooms that finally function for a modern family, and whole-home remodels that respect the home’s original character. Each service has its own detailed page for this city.
General Contractor in South Pasadena
General contracting in South Pasadena frequently starts with a structural question: is that cracked plaster cosmetic or a sign of foundation movement, is that sagging porch beam safe, can this 1920s floor carry the weight of new cabinetry? We assess the full picture, pull the appropriate permits, and coordinate plumbing, electrical, and framing crews under one written price. Older homes here often hide surprises behind the walls, which is why our written price is not a guess. We line-item what we know, and we tell you before anything changes on the day of the job. See General Contractor in South Pasadena for full details.

Bathroom Remodeling in South Pasadena
Bathrooms in South Pasadena’s older homes are usually the smallest rooms with the biggest problems: 5-foot-by-7-foot layouts from the 1930s, cast iron plumbing at the end of its life, and floors that slope enough to affect shower drainage. We handle the full scope from demo to tile, including replacement of the old galvanized supply lines and adding proper ventilation, which many of these pre-war bathrooms never had. Permits are pulled when the project moves plumbing inside walls, and the final written estimate reflects that from the start. Details are on the Bathroom Remodeling in South Pasadena page.

Home Remodeling in South Pasadena
Whole-home remodels here balance two competing goals: you want a modern kitchen and open living space, but the city’s charm rules and your home’s original architecture deserve restraint. We have worked on remodels where the second story had to be designed to sit behind the existing roofline so the street view stayed true to the 1920s character. Interior work commonly includes structural retrofitting for seismic safety, rewiring, and moving walls that were never meant to carry today’s floor plans.
