Why Penhallow Remodeling Is Hillsborough’s Preferred General Contractor Company
Hillsborough homeowners tend to ask the same three questions when we first sit down: what does the city actually require, what will it really cost, and what happens if something fails after the crew leaves. We answer all three in writing before demolition starts.
Trevor Nash leads every Hillsborough engagement. He knows what the Architectural Advisory Committee asks for on Spanish Colonial Revival and Tudor Revival exteriors because he has walked dozens of Hillsborough applications through design review. He also knows how long review takes, which means our project schedules account for the multi-month AAC window rather than pretending it does not exist. Hillsborough customers consistently tell us the same thing: the written price held, the crew arrived in the window we gave them, and the job site was left clean every afternoon. That is the standard, not a one-off.
Our Hillsborough clients get background-checked, uniformed technicians on site, a live person answering the phone around the clock, and project materials from recognized trade brands. The crews serving Hillsborough understand hillside access, clay soil, and mature landscaping that complicates staging. We have worked properties off Chateau Drive, around Lakeview Drive, and through the winding lots near Burlingame’s western edge. That local pattern recognition matters when a retaining wall starts to move or a flat roof lifts shingles in a January storm.
Every project gets a written guarantee. If work fails within the guarantee period, we come back and fix it at no charge. No service call fee, no re-inspection fee, no arguing about who caused it. That promise is written into every Hillsborough contract.
Construction Company in Hillsborough
A construction company in Hillsborough handles projects that go beyond a single trade: structural changes, additions, ADUs, garage conversions, and exterior envelope work where wind-load ratings and drainage details have to clear city review. A typical roof replacement on a Hillsborough estate runs $8,000 – $20,000, impact window installation runs $8,000 – $25,000, and a home addition runs $45,000 – $130,000. These are real Hillsborough market ranges, not national averages.
Architectural Advisory Committee Compliance
Hillsborough’s Architectural Advisory Committee requires design review with elevations, material samples, and neighbor notification for nearly all exterior work. That is a multi-month process no one skips. Homeowners who bypass the pre-application consultation often submit full plans that get returned for redesign, adding three to six months to a project that should have been permitted in weeks. Our team handles the AAC pre-application with city planning staff before full plans go in, so the review cycle moves without surprises.
Wind-Rated Exterior Work
Hillsborough sits on the eastern foothills of the Coast Range, which means hillside exposure drives roof edge, ridge, and fascia connections harder than flat Peninsula lots. Standard wind-load details that pass in Burlingame fail here. We specify connections rated for the exposure category the city requires, and we document that rating in the permit package so the final inspection sign-off happens on schedule.
Remodeling Contractor in Hillsborough
A remodeling contractor in Hillsborough handles kitchens, bathrooms, whole-home transformations, and interior structural changes inside homes where lath-and-plaster walls and post-and-pier or concrete perimeter foundations are the norm. A kitchen remodel runs $14,000 – $45,000, a small kitchen runs $9,000 – $20,000, a bathroom runs $9,000 – $28,000, and a small bathroom runs $5,000 – $12,000. Cabinet lines, countertop materials, and whether walls move drive the number up or down in predictable ways.
Historic-Age Interiors and Sensitive Upgrades
Hillsborough’s housing stock includes a dense concentration of Spanish Colonial Revival, Mediterranean, Tudor Revival, and Colonial estates built between the 1920s and 1950s. Many have original lath-and-plaster interiors and aging foundations. Working with those materials and structures requires a contractor who respects what is behind the wall before cutting into it. We document existing conditions before framing starts, so changed orders come from visible discoveries, not hidden surprises.
Clay Soil and Slope Drainage
Hillsborough lots slope, and the clay-heavy soils expand and contract through wet winters and dry summers. That movement stresses foundations, flatwork, and retaining walls in ways flat valley lots never see. We surface drainage and grade as part of the design scope rather than treating them as afterthoughts, because the remodel that ignores them fails within a few seasons.
Trusted Brands We Service in Hillsborough
We install and service work from Cambria, Silestone, Caesarstone, KraftMaid, Wellborn, Kohler, and Moen. Hillsborough homeowners often ask about prefab and panelized options too. We have worked with and around systems from Abodu, Cover, and Dvele, and we know which approvals those products need from the city. Because we stock familiar parts and keep relationships with local suppliers, material lead times for Hillsborough jobs stay short. When a specific tile or fixture is specified in a Hillsborough design review package, we match it exactly rather than substituting something the committee has not seen.
Common General Contractor Problems We See in Hillsborough Homes
- Skipped AAC pre-application. Homeowners submit full plans without elevations, material samples, or neighbor notifications, and the city returns them for redesign. The project loses three to six months before a hammer swings.
- Wind-load details copied from flat-lot plans. Roof edge, ridge, and fascia connections are specified for standard exposure, not hillside exposure. The roof lifts in a winter storm, and the insurance claim gets denied because the permit did not document the right rating.
- Clay-soil foundations poured without drainage. New slabs and flatwork go in without addressing expansive clay movement and slope water flow. Cracks appear within two seasons, and retaining walls start to lean.
- Exterior work done without AAC design approval. A homeowner or an out-of-town contractor replaces windows or siding without the required review. The city issues a stop-work order, and the project waits months while the paperwork gets corrected.
Pricing for General Contractor in Hillsborough, CA
Hillsborough pricing runs higher than San Mateo or Burlingame because the housing stock is older, the lots slope, and the design review process adds time. Here are the actual market ranges we quote:
| Project Type | Typical Hillsborough Range |
|---|---|

| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |

FAQs About General Contractor in Hillsborough
Hillsborough homes on hillside exposures typically need components rated for a higher uplift category than flat-lot roofs in Burlingame or San Mateo. The exact rating depends on the roof’s height, slope, and exposure category as defined by the building code, and the city’s permit path requires documentation of that rating. Clay barrel tile, concrete tile, standing seam metal, and impact-rated shingles all carry wind-load certification when specified in the right profile and fastening pattern. We specify the products and the connection details together and submit that documentation with the permit package. Call (936) 259-2607 for a wind-load assessment on your Hillsborough roof.
AAC review adds two to six months to any Hillsborough project involving exterior elevation changes, material changes, or neighbor notification. The committee requires drawings, material samples, and sometimes a site visit. Plans that skip the pre-application consultation often come back with redesign comments that restart the clock. We build the AAC window into our schedule before work starts and handle the pre-application meeting with city planning staff so the full submission is complete the first time. Call (936) 259-2607 to get the review timeline for your specific project.
A compliant Hillsborough quote includes connection hardware rated for the site’s exposure category, documentation of the wind-load standard being met, and the permit path with AAC review if required. Cheap quotes often copy standard flat-lot details, omit the exposure documentation, and skip the review process entirely. That leaves the roof vulnerable in a winter storm and gives your insurance company a reason to deny a claim. Demand the rating in writing. Then call (936) 259-2607 and ask us to put a compliant number in front of you.
Expansive clay soils in Hillsborough expand and contract through seasonal wet-dry cycles, which stresses slabs, foundations, and flatwork. Sloped lots concentrate runoff, and without surface drainage and proper grading, water erodes the soil behind retaining walls and undercuts foundations. A proper Hillsborough scope includes deeper pier footings where slopes require them, surface drainage that moves water away from structures, and retaining wall design that accounts for soil pressure. Skipping those line items cuts cost up front and creates structural failures within a few seasons. Call (936) 259-2607 for a foundation or drainage assessment on your Hillsborough lot.
You need the permit drawings that show the wind-load rating and connection details, the manufacturer’s product data sheet with the tested rating, and the final inspection sign-off from the city. In Hillsborough, where the AAC reviews exterior work, the approval letter from the committee is part of that chain. We compile and hand over that documentation on every exterior project we complete, so you have what the insurance adjuster asks for. Call (936) 259-2607 to make sure your next Hillsborough exterior project is documented correctly from the start.
