Fast, Reliable General Contractor Across Hillsborough
If you’re planning a kitchen remodel, bathroom upgrade, or home addition in Hillsborough, you need a general contractor who understands this town’s specific building rules before the first wall comes down. Hillsborough enforces strict floor-area and hillside grading rules, so nearly every addition or ADU here needs geotechnical and drainage review before framing starts, a step neighboring Burlingame or San Mateo typically doesn’t require. Sawyer Remodeling has worked through that process enough times to know exactly what the town will ask for and when. Call (254) 272-5876 to talk through your project and get a written price before any work begins.
Why Sawyer Remodeling Is Hillsborough’s Preferred General Contractor Company

Hillsborough homeowners keep our number because we run every job under The Relay Visibility Guarantee: a live arrival time, photo updates before and after each phase, and a written price that lands in your hands before a single tool is picked up. Luca Romano leads our crews with a simple rule: the number on the invoice is the number you approved. No change orders buried in fine print, no allowances that quietly double mid-project.
Our reviews from Hillsborough customers consistently point to the same things: the written price held, the crew showed up when the app said they would, and the punch list actually got finished. We send background-checked, uniformed technicians on every job, so you know exactly who’s walking into your home before they arrive. When a project needs city inspection sign-off, we coordinate the schedule and stay on site until the inspector leaves.
We also answer the phone. A live person picks up 24/7, which matters when you’re trying to line up a remodel around a work schedule and a Hillsborough permit timeline that won’t wait.
Styles & brands we work with







General Contractor Services in Hillsborough
General Contractor Services in Hillsborough cover the full sequence of a remodel or addition: scope definition, permit drawings, geotechnical review when the lot slopes, demolition, rough-in, inspection sign-off, and finish work. A typical Hillsborough kitchen remodel runs $14,000 to $45,000, and a bathroom remodel lands between $9,000 and $28,000, depending on whether you’re moving plumbing, pulling permits for structural changes, or restoring finishes in a home built before 1970. Hillsborough’s housing stock leans older, which means we often find wiring, subfloor, or framing conditions that need correction before new finishes go in.
Permit-Ready Planning
Hillsborough Town Hall reviews floor-area calculations and hillside grading plans closely. We assemble the site plan, structural notes, and drainage documentation the town expects, then walk the permit through plan check so you’re not stuck in a resubmission loop. Our written scope includes the permit line item and the inspection milestones that go with it.

Change-Order Discipline
We took on a kitchen and bath remodel off Pinehill Road where the homeowner wanted KraftMaid cabinets and a Cambria island. Our tech opened up the wall and found the existing subfloor wasn’t level, so we added a change order for floor leveling and re-rough-in of the plumbing before inspection sign-off. The finished scope of work included new Silestone counters and Kohler fixtures, and we closed out the punch list in two visits. That’s how change orders should work: discovered, priced in writing, and approved before the work proceeds.

Construction Company in Hillsborough

Construction Company work in Hillsborough means more than swinging hammers; it means coordinating geotechnical engineers, drainage contractors, town inspectors, and material deliveries on streets that are often narrow and steep. A Hillsborough home addition runs $45,000 to $130,000, while an ADU construction project lands between $90,000 and $220,000. Garage conversions fall in the $30,000 to $80,000 range. Those numbers assume the project is permitted, inspected, and built to the town’s hillside standards.
Hillside-Ready Crews
We’ve built on enough Hillsborough lots to know that a flat-lot estimate kills budgets on a hillside. Crews account for retaining considerations, drainage swales, and access constraints before we price the job. That’s why our written price includes the geotechnical and drainage line items Hillsborough requires, not as a surprise later.
Inspection-First Sequencing
Treating permit and inspection sign-off as a formality is the most expensive mistake we see in Hillsborough. Once rough-in is covered, the town can require walls opened back up. We sequence every job so the inspector sees plumbing, electrical, and structural rough-in before drywall or subfloor goes down, and we schedule the inspector early enough that the calendar doesn’t stall.
Trusted Brands We Service in Hillsborough
Hillsborough homeowners tend to know exactly what they want, and we stock and service the brands they ask for by name. That includes KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, Kohler and Toto fixtures, and James Hardie siding. If you’re comparing prefab options from companies like Abodu or Dvele for an ADU, we can walk you through how those systems interface with Hillsborough’s site requirements. Because we order directly through manufacturer-backed channels, we can often pull local inventory for Hillsborough projects faster than a big-box order desk, and every material carries the manufacturer’s warranty behind our install.

AfterCommon General Contractor Problems We See in Hillsborough Homes
- Hillside lot surprises: Bidding a hillside addition on flat-lot assumptions and then discovering the geotechnical and drainage requirements Hillsborough imposes means the owner eats a costly change order. We price the geotech and drainage review into the original scope so that doesn’t happen.
- Covered rough-in before inspection: Hillsborough inspectors need to see plumbing, electrical, and structural work before walls and subfloor close up. Letting rough-in get covered triggers a redo, and that’s avoidable with proper sequencing.
- Allowances set too low: Setting allowances for cabinets, counters, and fixtures based on mainland prices breaks budgets when Hillsborough projects require custom fabrication and hillside delivery. Our line-item allowances reflect the local supply chain, not a national average.
- Older home conditions: Many Hillsborough homes were built in the 1960s and 1970s, which means subfloors aren’t always level and wiring doesn’t always meet current code. We open walls with a plan for what we’ll likely find and price correction work honestly up front.

FAQs About General Contractor in Hillsborough
Yes, if you’re moving plumbing, electrical, or structural walls, Hillsborough requires a permit, and the town inspects rough-in before finishes go in. Cosmetic-only updates like countertops and backsplashes may not need one, but we’ll tell you exactly what your scope triggers. Call (254) 272-5876 and we’ll walk your project against the town’s current requirements, free.
Allowances are placeholder dollar amounts for materials like cabinets, counters, and fixtures, and in Hillsborough they’re often set too low because custom fabrication and hillside delivery cost more here than mainland pricing assumes. Sawyer Remodeling uses line-item allowances based on local supplier quotes, not national averages, so your draw schedule doesn’t blow past the estimate. If you want to see how we build allowances differently, call us for a sample scope.
A change order is a written adjustment to your contract price, and you’ll see one any time we uncover a condition that wasn’t visible when we priced the job, like an unlevel subfloor off Pinehill Road or drainage work the town requires once the lot is opened up. We price it in writing and get your approval before any additional work starts. No surprise invoices at the end.
A Hillsborough home addition typically runs six to twelve months from permit submittal to final inspection, with geotechnical and drainage review adding time up front that neighboring towns don’t require. We give you a milestone calendar in writing before work starts, and you’ll see photo updates at every phase. Call (254) 272-5876 for a realistic timeline on your specific scope.
Yes, we regularly pair KraftMaid or Wellborn cabinetry with Cambria or Silestone countertops on Hillsborough kitchens, and we order both through manufacturer-backed channels. The material warranty follows the install, and our 365-Day Done Right Promise covers our workmanship for a full year. If you have a specific combination in mind, call us and we’ll price it line-by-line.
