Fast, Reliable Home Remodeling Across Los Altos
Home remodeling in Los Altos means working with a housing stock most Silicon Valley contractors rarely see up close: 1940s through 1970s ranch and Eichler-era homes on generous lots, many of them now due for full rebuilds, second-story additions, or ADU construction. Those projects come with real challenges: knob-and-tube wiring, undersized electrical panels, and original cast-iron plumbing hiding behind finished walls. We handle all of it under one roof, from structural work through finished surfaces. If you’re planning a kitchen overhaul, bathroom remodel, or a whole-home renovation in the 94022, 94023, or 94024 zip codes, call Brookside Contractors at (833) 725-3508 for a free estimate.
Why Brookside Contractors Is Los Altos’s Preferred Home Remodeling Company
Los Altos homeowners tell us the same thing again and again: they’re done juggling three separate contractors who don’t talk to each other. That’s exactly why our Home Remodeling team operates as one contractor across every phase, from demolition and rough-in through cabinetry, countertops, and final trim. One point of contact, one schedule, one accountable party when something goes sideways.
We know the city’s permitting process because we’ve worked through it dozens of times. Old Los Altos, North Los Altos, and Loyola Corners each come with their own quirks under the city’s single-story-neighborhood design review and tree-protection ordinance. That matters when a heritage oak sits 15 feet from your proposed foundation. We also understand what happens when you open a wall in a 1950s ranch and find fabric-wrapped wiring that has to go. Our estimates account for that reality upfront.
For Home Remodeling in Los Altos, our team brings brand depth most local GCs can’t match. You want Cambria quartz in the kitchen, GAF roofing overhead, and Kohler fixtures in the bath? We’re authorized to install all of it. You’d rather balance budget with mid-tier picks like Silestone and IKO? That’s your call, not ours. Your project, your brands. We match the material to the project and the budget, then we manage everything to final walkthrough.

Styles & brands we work with







Luxury Home Remodeling in Los Altos
Luxury Home Remodeling in Los Altos generally means one of two things: a high-end kitchen or primary bath overhaul in a mid-century home, or a larger structural project like a second-story addition that transforms a single-story ranch into a modern two-level home. Los Altos homeowners choosing this path often live in the 94022 or 94024 zip codes and are working with lots that can support vertical expansion, assuming the city’s design review and tree-protection rules cooperate.
Kitchen remodels in Los Altos typically run $14,000 to $45,000 depending on cabinetry tier, countertop material, and whether walls move. Bathroom remodels land between $9,000 and $28,000. Walk-in shower installations range from $4,500 to $12,000. When the project expands into a full home addition, expect $45,000 to $130,000.
High-End Kitchen and Bath Work
We install KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and fixtures from Kohler, Toto, Moen, and Grohe. The material selection process is straightforward: you choose the tier, we handle procurement, delivery, and installation. No subcontractor hand-offs. No “that’s the cabinet guy’s problem.”
Second-Story Additions and Full Interior Renovation
Adding a second story to a Los Altos ranch requires structural engineering, design review, and often a tree arborist’s report before plans are approved. We coordinate that entire entitlement calendar. Once permits clear, our crew handles framing, mechanicals, finishes, and everything between. One contractor, every phase.
Full Home Remodel in Los Altos
Full Home Remodel work in Los Altos is increasingly common as buyers acquire older ranch and Eichler-era properties in 94022 and 94023 with the intention of rebuilding from the inside out. These projects often include a kitchen and bath remodel, window and door replacement, electrical and plumbing upgrades, and sometimes a new roof or siding. The range we typically see is $45,000 to $130,000 for a comprehensive interior renovation, though larger structural changes push beyond that. ADU construction as part of a full-home remodel runs $90,000 to $220,000.
Whole-Home Interior Renovation
We open walls, replace what’s failing, and rebuild to current code. That includes knob-and-tube removal, panel upgrades, cast-iron drain replacement, and often new insulation and drywall throughout. The work is disruptive, but we sequence it so you’re never living in more chaos than necessary.
Garage Conversions and ADU Construction
Los Altos lots are large by Silicon Valley standards, which makes garage conversions and detached ADUs realistic options. Garage conversions run $30,000 to $80,000. We work with Abodu and Dvele prefab ADU systems where they fit the lot, and we handle site work, foundations, utilities, and final connection ourselves.
Trusted Brands We Service in Los Altos
Brookside Contractors is authorized to install a deep roster of industry brands, and for Los Altos customers that means genuine choice rather than a forced spec. On the hardscaping and outdoor side, we work with Belgard, Unilock, and Tremron pavers, plus ActiveYards fencing. Inside the home, our catalog spans KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, GAF and Owens Corning roofing, James Hardie siding, and PGT, CGI, and Therma-Tru windows and doors. Because we’re based nearby in Morgan Hill, we can bring samples to your Los Altos home quickly and coordinate material deliveries without the lag a distant contractor would face.

AfterCommon Home Remodeling Problems We See in Los Altos Homes
- Knob-and-tube wiring behind finished walls. Most 1940s and 1950s Los Altos homes were built with it, and many still have live circuits feeding outlets and light fixtures. Once we open a wall for a kitchen or bath remodel, any exposed knob-and-tube must be replaced to pass inspection. That’s a code requirement, not an upsell.
- Undersized electrical panels. Original 100-amp panels can’t support a modern kitchen with an induction range, double oven, and dedicated hood circuit. A remodel that touches the kitchen or adds square footage almost always triggers a panel upgrade to 200 amps. We write that allowance into the contract before work starts.
- Cast-iron and galvanized plumbing at the end of its life. Los Altos homes built before 1970 commonly have original cast-iron drain lines that are rusting through or galvanized supply pipes so corroded they restrict flow. Moving a bathroom or kitchen fixture means cutting into those lines, and code requires replacement of anything exposed that fails inspection.
- Heritage tree root zones that reshape the plan. A mature oak or redwood on a Los Altos lot isn’t just landscaping. Under the city’s tree-protection ordinance, the root zone can legally limit where a foundation, addition, or ADU can go. We’ve seen arborist reports force a foundation to shift eight feet sideways. The entitlement calendar, not construction speed, ends up setting the timeline.
On a 1950s ranch in North Los Altos, we opened up a load-bearing wall between the kitchen and living room and found knob-and-tube wiring feeding the old circuit plus a panel too undersized for the new range and hood. Neither was visible at bid time. We stopped, documented it in a written change order with the electrical rough-in priced line by line, and got owner sign-off before our electrician touched a wire. The inspection sign-off on the new panel came through without a re-quote surprise. That’s how we work.
Pricing for Home Remodeling in Los Altos, CA
Los Altos pricing runs higher than most of the Bay Area because the housing stock is older and entitlement friction is real. A kitchen remodel here typically costs $14,000 to $45,000. Bathroom remodels run $9,000 to $28,000. Home additions land between $45,000 and $130,000, while ADU construction ranges from $90,000 to $220,000. The biggest variables are what’s hiding behind the walls, whether the city’s design review or tree-protection rules add time, and the material tier you select. Here’s how common line items break down:
| Project | Typical Los Altos Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |

We’ll walk the property with you and give you a line-item scope, not a vague number.

FAQs About Home Remodeling in Los Altos
Because 1940s to 1970s homes in Los Altos hide code-defect wiring, plumbing, and framing that no walkthrough can see. Once walls are open, the inspector will flag knob-and-tube, undersized panels, and corroded cast-iron that must be replaced. We prevent the moving-quote problem by writing allowances into your contract upfront and requiring written change orders with line-item pricing before any newly discovered work begins. Call (833) 725-3508 to get an estimate that accounts for what’s actually in your walls.
Yes. When a remodel opens finished surfaces and exposes existing wiring or plumbing, the inspector will require anything not up to current code to be brought to code. That includes knob-and-tube removal, panel upgrades, and replacement of failing cast-iron or galvanized lines in the affected area. It’s not optional, and any estimate that ignores it is guessing.
It can force the foundation to move, shrink, or trigger a full arborist review before design approval. Los Altos’s tree-protection ordinance gives mature oak and redwood root zones legal standing that overrides your preferred footprint. We have dealt with this repeatedly in Old Los Altos and North Los Altos, and we order the arborist report early so the entitlement calendar doesn’t stall your permit. For help scoping a project around your trees, call (833) 725-3508.
Homes along the wildland-urban interface face WUI fire-hardening requirements from the building department: ignition-resistant roofing, ember-rated vents, and non-combustible siding in certain zones. If your remodel includes a roof replacement, window replacement, or siding work, those materials must meet the WUI standard. We handle that specification work as part of the scope.
Inspection-first scoping, written allowances, and pre-approved change orders. We walk your home before the estimate, open what can reasonably be opened without demolition, and price the known unknowns. When a surprise shows up mid-project, you see the cost in writing before we touch it. No re-quotes after the fact. Call (833) 725-3508 for a free estimate on your Los Altos remodel.
