Why Penhallow Remodeling San Jose Is Los Altos’s Preferred General Contractor Company
Los Altos homeowners tend to ask the same questions when they call: how long will design review take, who handles the permit drawings, and what happens if the city pushes back on a setback variance. We answer those questions with experience pulled from actual jobs in the area, not scripted talking points. Our General Contractor in Los Altos team works regularly with the city’s planning department and building division, which means we know what triggers a delay and what does not. That kind of local knowledge saves weeks.
You will see our uniformed, background-checked technicians arrive in marked vehicles with a written scope and a written price in hand. There is no change-order roulette. Every job gets a 365-Day Done Right Promise, written on the estimate itself. If something fails inside that year, we come back and fix it at no charge. No re-inspection fee, no service call, no argument.
Styles & brands we work with
Hire a General Contractor in Los Altos
Hire a General Contractor in Los Altos when the job involves structural work, multiple trades, or anything that triggers design review by the city. A high-end kitchen remodel in Los Altos typically runs $14,000 – $45,000 depending on cabinet line, countertop material, and whether you are moving plumbing or walls. A bathroom remodel runs $9,000 – $28,000. The number moves based on whether you are keeping the existing footprint or reconfiguring the room, and whether the existing subfloor and framing are sound.
Kitchen Remodel
Most Los Altos kitchens we work on are in homes built between the 1950s and 1980s, which means the layout was designed for a different era. Removing a load-bearing wall to open the kitchen into the dining room changes the cost and the engineering review. We write the price after seeing the existing conditions, not before, and then we hold that number for the life of the project.
Bathroom Remodel
Bathrooms in Los Altos ranch homes often hide rot behind the shower tile or under the vanity. We do not order cabinets or countertops until we know what the substrate looks like beneath the old finishes. That sequencing prevents the surprise change order you would get from a contractor who priced the job without pulling the old tile first.
General Contractor Services in Los Altos
General Contractor Services in Los Altos go beyond swinging a hammer. The drawings, the permit application, the engineering letters, the trade coordination, the material lead times, the inspections. We handle all of it under one written contract so you are not chasing an electrician who is waiting on the plumber who needs the cabinet shop to confirm a dimension. A home addition in Los Altos runs $45,000 – $130,000 depending on size, foundation type, and whether the city requires a geotechnical report, which many hillside lots do.
Whole Home Remodel
Whole-home remodels on Los Altos properties tend to move at the pace of design review, not demolition. We sequence the work so that permits are moving while materials are being ordered, not the other way around. The written price includes allowances for custom millwork, fixtures, and finishes, and we reconcile those allowances with you before any overage is billed.
Room Addition
Additions in Los Altos often trigger setback reviews and, in North Los Altos, septic system capacity checks. We flag those items early so the budget does not become a guessing game. The price is fixed before ordering, which means you are not funding someone else’s poor planning.

AfterCommon General Contractor Problems We See in Los Altos Homes
- Septic system triggers on North Los Altos remodels: Many homes north of downtown still use septic systems, not sewer connections. A kitchen or addition that adds plumbing fixtures can force a septic upgrade before framing begins, adding cost and weeks to the schedule.
- Design review timelines underestimated: Los Altos design review is thorough and slow. Contractors who order custom materials too early end up paying storage fees while permits stall, and some manufacturers start the warranty clock on delivery, not installation.
- Subfloor rot hidden under old kitchens: Ranch homes from the 50s and 60s often have water damage under the sink or near the dishwasher. When the old flooring comes up, the scope changes. We price for that contingency in writing, so it does not become a surprise change order.
- Change orders after the final draw: A contractor who cannot reconcile allowances in writing before closing out the job is not protecting you. We put the reconciliation on paper, line by line, before the last payment is due.

FAQs About General Contractor in Los Altos
It can. Many North Los Altos homes still operate on private septic systems, and adding plumbing fixtures like an island sink or a pot filler can push the system beyond its approved capacity. The city will require an evaluation before issuing the permit. We just finished a full kitchen remodel on a 1960s ranch in North Los Altos where the existing septic system could not handle the new island’s plumbing rough-in. Our crew coordinated the septic upgrade with the city’s slow permitting process, then brought in custom white oak cabinetry and a Cambria quartz island, all while keeping the homeowner’s draw schedule on track. That is what working with a contractor who knows Los Altos looks like. Call (669) 274-2362 to have us check your property’s situation.
Plan on four to eight weeks beyond what a standard permit would take, and sometimes longer if the design triggers planning commission review or public comment. The key is to sequence material orders behind permit approvals, not ahead of them. We write the schedule around the city’s review calendar, and we put that timeline in writing before we start.
Lead times. Custom cabinetry, architectural windows, and specialty stone runs on a factory calendar that does not care about your project. KraftMaid and Wellborn cabinets can run six to ten weeks depending on door style and finish. Cambria slabs are usually in stock, but unique profile cuts and edge details add shop time. We order materials early only when the permit is already moving, so the clock does not run out while parts wait in storage. Call (669) 274-2362 to talk through what your specific selections would do to the schedule.
It helps more than you would think. Los Altos architects and designers have specific expectations about millwork tolerances, lighting placement, and finish schedules, and a contractor who has not worked with them will stumble. We have built working relationships with several local design firms, which means the drawings we receive already speak a language we know how to build from. That coordination keeps the project moving and keeps the architect from having to defend avoidable field errors.
The price, the schedule, the scope, the allowance list, the payment draw schedule, and the guarantee. Every Penhallow Remodeling contract includes a written 365-Day Done Right Promise: if the work fails inside that year, we fix it at no charge. We also include a free second visit if a repair fails, no service call or re-inspection fee. If a contractor will not put those words on paper, find another contractor. Call (669) 274-2362 for a written estimate you can actually hold.
