Why Timberline Contractors Is Palo Alto’s Preferred General Contractor Company
Palo Alto homeowners don’t just need someone to swing a hammer. They need a contractor who has pulled permits through the city’s design review process and knows what a heritage oak root zone means for a foundation layout. Nelson Fung has built Timberline Contractors around that reality. We walk every Palo Alto job with the assumption that walls hide something: knob-and-tube wiring, notched joists, failed waterproofing from a 40-year-old shower pan. Our estimates account for that before we open anything up.
Our customers in Professorville, Crescent Park, and the south Palo Alto tracts keep calling us back because we write allowances into the contract for exactly those discoveries. That’s not a sales tactic. It’s how you avoid a five-week remodel turning into a four-month surprise. We also respond quickly to Palo Alto jobs because we’re based nearby in Chinatown, CA, and we schedule our crews to minimize trips across the Bay. When a change order hits, we price it in writing and wait for your approval before touching the next stud.

General Contractor Services in Palo Alto
General Contractor Services in Palo Alto means coordinating every trade, material order, and inspection across a whole project, whether that’s a kitchen remodel off Middlefield Road or an ADU behind a Crescent Park rancher. A typical kitchen remodel in Palo Alto runs $14,000 – $45,000, while a bathroom remodel sits at $9,000 – $28,000. We pull permits, manage the subs, and hold the schedule. Here’s what that looks like on the ground.
Full-Scope Remodeling
We handle interior and exterior scope under one contract. A Palo Alto remodel might start with a kitchen expansion, run through a James Hardie siding replacement, and finish with a paver patio off the dining room. You get one point of accountability from the foundation to the ridge cap.

Pre-Construction Inspection and Change Order Protocol
Before we demo anything in a Palo Alto house, we inspect what’s behind the drywall, under the subfloor, and inside the attic. If we find something the permit will force us to fix, you see a written change order with a line-item price before we touch it. No verbal promises, no mystery line items at the end.

Construction Company in Palo Alto
Construction Company work in Palo Alto covers the structural and envelope side of a project: foundations, framing, roofing, siding, windows, and exterior waterproofing. Roof replacements in Palo Alto typically run $8,000 – $20,000, and home additions fall between $45,000 and $130,000. We do the work that keeps the inside of the house dry and the outside standing straight.
Structural and Seismic Upgrades
Palo Alto’s older wood-frame homes were built before current seismic codes. When we open up a 1920s bungalow near Professorville, we regularly find undersized headers and foundation bolts that would fail a shear-wall inspection. We fix the framing, add hold-downs, and bring the connection points to code before we close anything up.
Exterior Envelope and Drainage
Wet winters and long dry summers in Palo Alto mean drainage and exterior detailing matter more than people expect. We flash windows, replace dry-rotted trim, and grade around foundations so the first heavy rain doesn’t find its way under the sill plate. GAF and CertainTeed roofing options give you real choices for fire-resistant materials near the foothills.
Trusted Brands We Service in Palo Alto
We stock and install from a roster of manufacturers we trust, and Palo Alto customers get direct access to those brands without having to coordinate with specialty showrooms. If you’re picking a kitchen faucet, we can spec Delta for a budget-conscious refresh or Toto for a premium build without changing contractors. Countertops run the same way: Silestone for solid value, Cambria when you want that deeper quartz selection. Blanco sinks, American Standard tubs, and a full line of GAF roofing round out the package. One contractor, every phase, with the showroom brought to the project.

AfterCommon General Contractor Problems We See in Palo Alto Homes
- Knob-and-tube and failed splices. We open walls in early-1900s Palo Alto homes and find old wiring buried behind plaster, sometimes spliced into newer romex by a previous owner. The permit process forces a fix; we plan for it in the estimate.
- Tree protection fences before demolition. Palo Alto inspectors expect heritage oak and redwood root zones to be fenced before demo starts. Skip that step and the project halts, possibly with a redesign.
- Notched or undersized framing. Old Spanish Colonial and Craftsman homes in Palo Alto often have load-bearing walls that were notched decades ago for plumbing or duct runs. A remodel opens that up, and the fix is structural, not cosmetic.
- Permit timeline surprises. Palo Alto’s design review process can add weeks before work starts. We build that into the schedule instead of pretending it doesn’t exist.

FAQs About General Contractor in Palo Alto
Expect to find conditions the original builder never intended: knob-and-tube wiring, notched joists, failed waterproofing, and framing that predates current seismic codes. In Palo Alto’s early-1900s homes near downtown and Professorville, this is normal, not rare. We run a pre-demolition inspection and write allowances into the contract so those discoveries don’t become budget emergencies. Call (866) 253-5808 if you’re planning work on an older home and want to know what you’re getting into.
It can redesign your project before you ever break ground. Palo Alto protects heritage oaks and certain native redwoods, and inspectors require tree-protection fencing around root zones before demolition starts. If your planned foundation, driveway, or addition sits too close to a protected tree, you’ll need to adjust the layout. We factor this into the design phase, not after the permit is filed. If you have a large oak near the proposed addition, call us at (866) 253-5808 before you commit to a floor plan.
Because Palo Alto’s planning and building department requires design review for many projects, and unpermitted work will catch up with you when you sell or refinance. A permit also triggers inspections on the work we uncover: electrical, framing, shear walls, drainage. We pull the permits, schedule the inspections, and make sure every sign-off happens before we close walls. Skipping that step saves time in the short run and costs much more later.
We stop work, document what we found, and issue a written change order with a revised scope and updated allowance before we touch the affected area. That’s exactly what happened on a 1920s Spanish Colonial bungalow in Professorville: our crew opened a kitchen wall and found knob-and-tube spliced into newer romex, plus a load-bearing wall that had been notched for a past plumbing rough-in. We paused work, brought in a structural engineer, and got the homeowner’s written approval on the revised header and electrical panel before proceeding. The job passed inspection sign-off on the first try. Call (866) 253-5808 if you want that same discipline on your project.
It starts with a pre-construction inspection and a review of your property’s tree and zoning constraints. Then we design the addition around Palo Alto’s design review requirements, pull permits, and build the foundation, framing, envelope, and finishes in sequence. A home addition in Palo Alto typically runs $45,000 – $130,000 depending on size and structural upgrades. The whole process, including permit timeline, usually takes four to eight months. Call (866) 253-5808 for a free estimate and we’ll walk you through what applies to your specific lot.
