Remodeling Company in Hillsborough, CA
Home renovation in Hillsborough means something different than it does almost anywhere else on the Peninsula. The town’s large-lot estates, many built between the 1940s and 1970s, sit on wooded hillsides where every addition, remodel, or rebuild has to answer to design review, tree ordinances, and geotechnical realities before the first wall comes down. Brookside Contractors has served Hillsborough since 2011, and we run renovation projects here with that terrain and process in mind from day one. Call (833) 725-3508 to talk through your project.
Why Hillsborough Homes Are Different
Hillsborough is a town of custom estates, not tract homes. The housing stock is dominated by large single-family residences on lots of an acre or more, with many original mid-century homes now facing major remodels or full tear-down rebuilds. Those homes were framed and finished to standards that made sense for their era, but they rarely meet today’s expectations for insulation, seismic reinforcement, electrical capacity, or open-plan living. A renovation here is almost never a surface refresh. It is structural work wrapped in high-end finishes, and it has to be planned as one continuous job.
The terrain drives decisions that flatland contractors never think about. Hillsborough’s steep, tree-covered hillsides mean excavation, retaining, and drainage are part of most projects. The Mediterranean climate – wet winters and dry summers – adds another layer: hillside erosion control during the rainy season is not optional, and fire-resistant detailing on exterior materials is a serious consideration every dry season. Protected heritage oaks and redwoods on a lot often dictate where a structure can go, and hillside grading permits routinely trigger geotechnical reports before a foundation is poured. A contractor who has not worked inside those constraints will burn time and budget learning them on your dime.
Styles & brands we work with
Our Main Hillsborough Services
Most Hillsborough homeowners come to us through one of two doors: they need a general contractor to run a complex, multi-trade project from permits to final walkthrough, or they are planning a whole-home remodel and want one company accountable for every phase.
General Contractor in Hillsborough
As a general contractor, we hold the license, coordinate every trade, and take responsibility for schedule and quality across the entire job. In Hillsborough, that often means managing design-review submittals, tree-protection plans, geotechnical reports, and phased inspections while keeping the build moving. We work with a full roster of brand partners across cabinetry, countertops, roofing, windows, doors, and fixtures so you are not locked into one supplier’s spec. Read more about how we run projects on our General Contractor in Hillsborough page.
Home Remodeling in Hillsborough
Whole-home remodeling is where the town’s housing stock and terrain meet. An original mid-century estate on a wooded lot is not a blank canvas – it has protected trees, slope setbacks, and an existing structure that often needs structural upgrades before finishes go in. We handle that under one roof: interior renovation, exterior work, roofing, windows, siding, and hardscaping, all coordinated as one project rather than a relay race between specialists. See our Home Remodeling in Hillsborough page for the full scope.

Home Renovation in Hillsborough
Home renovation in Hillsborough is the work of bringing a mid-century hillside estate up to the way people live now: open kitchens, larger primary suites, modern systems, and exterior hardscaping that actually works with the slope instead of fighting it. Renovation here almost always involves structural changes, not just finishes, because the original homes were built for a different era. One contractor, every phase – that is how we approach it, and you can read more about our process on the Home Renovation page.
Home Renovation Contractors
Signs you need it
Your Hillsborough home has original electrical or plumbing, rooms that do not connect the way you live, or finishes that no longer match the quality of the rest of the property.
What it costs in Hillsborough
A full home renovation on a large-lot Hillsborough estate typically runs $45,000 to $130,000 or more depending on scope, structural work, and finish tier.
How we do it
We start with a structural and systems assessment, map the permit and design-review path, then plan demolition, rough-in, structural, and finish phases as one continuous schedule under one crew.
Home Renovation Companies
Signs you need it
You are comparing multiple bids and want a single company that can show real depth across every trade rather than a generalist who subs out the hard work.
What it costs in Hillsborough
Kitchen remodels inside a Hillsborough renovation run $14,000 to $45,000, while bathroom remodels run $9,000 to $28,000 depending on fixtures and waterproofing scope.
How we do it
We match materials to the project – from value-tier cabinetry through Cambria countertops and Kohler or Moen fixtures – and keep every line item transparent so you choose where to spend.
What Home Renovation Costs in Hillsborough
| Item | Typical range in Hillsborough |
|---|---|
| Kitchen remodel | $14,000 – $45,000 |
| Bathroom remodel | $9,000 – $28,000 |
| Home addition | $45,000 – $130,000 |
Will the Hillsborough design-review process delay a home renovation?
Possibly, and that is why we plan for it from week one. Hillsborough requires design review for most exterior changes and additions, and protected trees or slope issues can extend the review timeline. A contractor who knows the process can sequence work so interior phases proceed while approvals finish.
Can we renovate a Hillsborough home in phases?
Yes. Many Hillsborough homeowners phase renovations to match budgets or approval timelines. We plan each phase with the full project in mind so rough-in, structural, and finish work never has to be redone later. Call (833) 725-3508 for a phased estimate.
Brands We Service in Hillsborough
We install and service fixtures and finishes from Moen, Blanco, Delta, and American Standard, among many others. Parts for the most common lines are stocked locally, and specialty pieces are typically ordered within days, not weeks. See the full roster on our brands page.

What Hillsborough Customers Say
"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."
— Alma Delgado"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Eric Ackerman"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."
— Diego Hernandez
