Fast, Reliable General Contractor Across Hillsborough
If you’re planning a remodel, addition, or full custom build in Hillsborough, the general contractor you choose will make or break the schedule and the budget. We’re Brookside Contractors, led by Nate Burrell, and we’ve managed architect-designed estate work across the Peninsula long enough to know that Hillsborough projects don’t run on generic timelines. Protected trees, hillside grading rules, and long-lead specialty materials set the calendar here, not labor. We plan around those constraints from day one. Call (833) 725-3508 for a free estimate and a straight answer about your project’s real timeline.
Why Brookside Contractors Is Hillsborough’s Preferred General Contractor Company
Hillsborough homeowners call us because we speak the language of design-review boards, geotechnical reports, and heritage tree ordinances without flinching. Our reputation in town is built on jobs where the building envelope had to shift six feet to save a redwood, or where the foundation plan changed after a soils engineer looked at the hillside. We don’t treat those steps as surprises. We treat them as the actual job.
Response time to Hillsborough is straightforward: we schedule site walks around your architect’s drawings, not after them. When you call (833) 725-3508, Nate Burrell or a senior project lead will walk the lot with you, flag the approval risks before they become delays, and give you a written line-item estimate. That’s the point at which most homeowners realize the difference between a contractor who’s built in Hillsborough and one who’s just quoting it.
Our General Contractor team handles the full scope under one license and one point of contact. From foundation to finish, inside and out.
Styles & brands we work with







Construction Company in Hillsborough
A Construction Company in Hillsborough handles what most remodeling firms won’t touch: structural work, new foundations on sloped lots, retaining walls, full tear-down or partial rebuilds, and room additions that have to clear design review before a permit is even pulled. On these projects, the contractor’s real job starts before the build, in the site plan and the approval sequence. A typical home addition in Hillsborough runs $45,000 – $130,000, and ADU construction runs $90,000 – $220,000 depending on site conditions and finish level.
Structural Scopes and Hillside Work
On a Hillsborough hillside, we coordinate the geotechnical engineer, the structural engineer, and the town’s design-review comments before the first excavation. That sequence is non-negotiable here. We’ve learned that a grading permit that looks straightforward often triggers a soils report, and a soils report can change the foundation design. We price that reality in writing, not as a surprise.
Additions and ADUs on Estate Lots
Room additions and ADUs on Hillsborough lots often share a complication: the buildable envelope is smaller than the parcel suggests because protected oaks and redwoods sit inside it. We map tree-protection zones early, because they dictate where an addition can go and how the foundation detail works. Our ADU experience includes prefab systems from manufacturers like Abodu and Dvele, which can compress the on-site calendar when the site itself cooperates.
Remodeling Contractor in Hillsborough
A Remodeling Contractor in Hillsborough needs to be more than a finish carpenter. The town’s housing stock skews toward large mid-century estates and newer custom builds, and nearly every kitchen or bath remodel we take on involves load-bearing walls, ceiling height changes, or window and door reconfiguration that touches the structure. Our Hillsborough work routinely pairs a kitchen overhaul with structural reframing, because the two can’t be separated cleanly on these homes. Kitchen remodels in Hillsborough run $14,000 – $45,000, with bathroom remodels at $9,000 – $28,000.
Kitchen and Bath Project Timing
What actually drives the calendar on a high-end Hillsborough kitchen is almost never the rough-in crew. It’s the lead time on custom cabinetry, specialty glass, or a sourced stone slab. We lock the allowance and the scope in writing before we order, then sequence the work so the site stays productive while materials are in transit.
Material Selection Without the Upsell
Your project, your brands. We match the material to the project, whether that’s KraftMaid or Wellborn cabinetry, Cambria or Caesarstone countertops, Kohler or Toto fixtures. We carry access to both premium and value tiers, so the decision is about what fits the house and the budget, not about what we happen to stock.
Trusted Brands We Service in Hillsborough
We install and service a broad roster of brands across hardscaping, exterior, and interior finishes, and we don’t push a default spec. If your Hillsborough project calls for a paver driveway or patio, we work in Belgard, Unilock, Techo-Bloc, and Tremron. For windows and doors, that means PGT, CGI, and Therma-Tru. For cabinetry, KraftMaid and Wellborn. The point is choice: you pick the tier, we deliver the install. For Hillsborough customers, we track local supply availability and order long-lead items early, so a 14-week glass lead doesn’t sit idle on the calendar.

AfterCommon General Contractor Problems We See in Hillsborough Homes
- Protected trees dictating the building envelope. A heritage oak or redwood on a Hillsborough lot can shift the entire floor plan. Tree-protection fencing and a revised site plan often come before the architect’s final room dimensions, not after.
- Wet-season erosion control on sloped lots. From November through March, a hillside excavation without proper silt fencing, hay bales, and drainage planning will lose soil into the street and draw a stop-work order. We phase grading around the rain calendar.
- Long-lead specialty items stalling the finish. Designer tile, architectural glass, and custom millwork carry 10 to 16-week lead times on the Peninsula. If the allowance isn’t fixed in writing before ordering, the homeowner eats a change order when the true cost and wait land.
- Fire-defensible detailing on estate homes. Dry-season wildfire defensibility is a real design constraint in Hillsborough. Fire-resistant siding, ember-resistant vents, and managed vegetation buffers aren’t optional add-ons; they’re part of the permit conversation on many lots.

FAQs About General Contractor in Hillsborough
Lead times set the schedule. On a high-end Hillsborough remodel, architectural glass, custom cabinetry, and sourced stone can run 10 to 16 weeks from approval to delivery, while our rough-in crews are available on normal construction timelines. We lock allowances in writing before ordering so the draw schedule absorbs the wait. The labor isn’t the risk; the ordering sequence is.
Protected heritage oaks and redwoods can define the buildable envelope on your lot. Tree-protection fencing and the site plan often get drawn before the architect finalizes room dimensions, and the design-review process will enforce those zones. We’ve had projects where the entire addition shifted several feet to preserve a tree. That’s not a delay; it’s the design.
Before we order any long-lead material. The scope of work, allowances, and draw schedule are fixed in writing first. That way, a 14-week glass lead or a custom millwork order doesn’t become a change order when the real cost and calendar land. Call (833) 725-3508 to get your estimate started.
Yes, on nearly every Hillsborough hillside with meaningful grade change. The town’s grading permit process routinely triggers a geotechnical report before any foundation work can start, and that report can change the footing design. We plan for it in the schedule and the price, not as a surprise line item.
We schedule excavation and grading for the dry months when possible, and we install erosion control before the first rain touches exposed soil. Wildfire defensibility gets designed in with fire-resistant siding, ember-resistant vents, and vegetation buffers where the lot requires it. Both are part of the permit conversation in Hillsborough, not retrofits after inspection.
