Remodeling Company in Los Altos, CA
Home renovation in Los Altos means working with what’s already here: mostly 1950s and 60s ranch homes on wide lots, built well before modern insulation standards, seismic codes, or open-concept layouts. The work we do in Los Altos runs toward full remodels, second-story additions, and backyard ADUs rather than quick repairs. San Mateo Construction brings one licensed general contractor to the whole job, from roofline to foundation, so you’re not juggling four separate trades on a permit-heavy Los Altos project. Call (855) 901-7266 to talk through your house and your lot.
Why Los Altos Homes Are Different
Los Altos is not a tract-home town full of identical floor plans. Much of the original housing stock is single-story California ranch from the post-war build-out, and those homes share a few characteristics that shape every renovation. Original knob-and-tube wiring is still common in 94022 and 94024, so any remodel that opens walls usually triggers a full electrical panel and rewiring scope. Shallow slab foundations and raised-perimeter foundations from that era rarely meet current seismic strapping requirements, which means a kitchen remodel can quietly grow to include foundation bolting once the walls come open. Galley kitchens and compartmentalized bathrooms are the rule, not the exception.
The climate is mild and dry-summer Mediterranean. No frost-depth requirements, no snow load to engineer for. What Los Altos gives us instead is winter rain, so drainage, grading, and lot-slope stabilization matter more than insulation alone. Homes on the hillside edges near Los Altos Hills and Loyola back onto mature oak and redwood canopies. That canopy is protected, and arborist review routinely reshapes foundation and excavation plans before a shovel hits the ground. If your lot has heritage trees, we plan around them from day one, not after the permit comes back with conditions.
And the permitting culture here is real. Los Altos runs a resident-driven, design-review-heavy planning process. We have served Los Altos since 2018, and the single most useful thing we tell homeowners is that patience with Los Altos planning is part of the job. A good contractor here sells a realistic schedule, not a fast one.
Styles & brands we work with
Our Main Los Altos Services
Two services dominate the calls we get from Los Altos homeowners: full general contracting for major scopes, and whole-home remodeling for kitchens, baths, and interior reconfiguration. Both run through the same Los Altos permitting reality, and both benefit from one accountable team.
General Contractor in Los Altos
When a Los Altos project spans multiple trades, roofing, windows, foundation work, framing, finishes, the general contractor is the person who keeps the whole schedule moving and the permit file clean. Our general contracting work in Los Altos ranges from second-story additions over existing ranches to full tear-down-and-rebuild scopes on wide lots in 94022 and 94024. We manage subcontractors, material procurement, city inspections, and quality control under one contract. If your project touches more than two trades, this is the service that removes the coordination burden from your plate. See our dedicated General Contractor in Los Altos page for what a full-scope project looks like here.
Home Remodeling in Los Altos
Home remodeling in Los Altos usually starts with a galley kitchen that no longer works or a bathroom that has not been touched since the Johnson administration. We handle kitchen remodels, primary bath rebuilds, and whole-interior refreshes, including the wiring and plumbing updates those 1950s walls tend to hide. The design-review process in Los Altos means we document materials and sight lines early, which keeps city comments from stalling your cabinet installation by six weeks. For kitchens, baths, and interior reconfiguration, our Home Remodeling in Los Altos page covers the specifics and the price ranges.

Home Renovation in Los Altos
Home renovation in Los Altos is rarely a cosmetic exercise. The ranch-era housing stock means most renovation projects uncover wiring, foundation, and drainage issues that were simply built to a different standard in 1962. The mild climate and wide lots make Los Altos an ideal place for additions and ADUs, but the tree canopy and design-review process add planning layers that a contractor from outside the area will not anticipate. Home Renovation under our roof means one licensed GC handles the entire scope, from roofline to foundation, including the permit file and the arborist review if your lot backs onto protected oaks.
Home Renovation Contractors

Los Altos pricing gets pushed upward by three local factors more than anything else: electrical and foundation modernization hidden inside 1950s walls, tree-protection requirements on oak-adjacent lots, and the longer design-review timeline that adds carrying costs. We quote line-item and fixed once the scope is set, so the number on your estimate is the number you pay unless you change the scope.

What Los Altos Customers Say
"Framing crew was meticulous and the walls are straight everywhere. Drywall goes on a lot better when the framing is right."
— Diego Hernandez"Ground up build. Permits, foundation, framing, all of it, and he ran the schedule tightly enough that the subs were never tripping over each other. Finished within a month of a fourteen month estimate."
— Bethany Novak"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Karim Khalil
