AfterRemodeling Company in Atherton, CA

Our crews serve Atherton from our San Francisco Bay Area dispatch office, and Trevor Nash stands behind every written quote we deliver. Call (936) 259-2607 to schedule your free estimate.
Why Atherton Homes Are Different
Atherton is the only incorporated municipality in the U.S. zoned exclusively for single-family residential use with a one-acre minimum lot size. That means virtually every construction project here is a multi-million-dollar custom estate build or major teardown-and-rebuild, not a quick bathroom refresh. Contractors operating in Atherton must navigate the town’s own small but exacting building department, mandatory arborist-certified heritage tree protection plans, and clients who routinely retain owner’s representatives and architects of record with zero tolerance for deviation from spec.
The housing stock is a patchwork of 1940s – 1970s ranch and traditional estates, many being demolished and replaced by contemporary or transitional custom homes for tech-wealth buyers, alongside a smaller number of Spanish Colonial and Craftsman-era properties from the 1920s – 1930s that require historically sensitive renovation. Because the town resisted subdivision for decades, parcels are large and original structures often predate modern seismic and drainage codes, creating complex retrofit and foundation upgrade requirements.
Atherton sits on a relatively flat, low-lying section of the Peninsula with a seasonally high water table, and winter rains from November through March can waterlog construction sites and complicate foundation excavation and concrete pours. This is a more acute drainage problem here than in hillside neighbors like Woodside or Portola Valley. Expansive clay soils common across the floor of the Bay plain require engineered foundation solutions, often deep piers or post-tension slabs, that add cost and lead time to every ground-up project.
Atherton’s protected heritage tree ordinance, covering native Valley Oaks and specimen trees across nearly every parcel, routinely forces project redesigns mid-permit. A contractor who hasn’t secured a town-approved tree protection plan and pre-construction arborist monitoring agreement can have a stop-work order issued before the first stake goes in the ground.
Our Main Atherton Services
While our home remodeling work spans every room, Atherton homeowners most often call us for these three focused services:
General Contractor in Atherton
As general contractors in Atherton, we coordinate the full chain of trades, engineering, and inspections that large-lot projects require. We pull permits through Atherton’s building department, schedule arborist monitoring for heritage tree compliance, and manage the structural engineers who design pier and post-tension solutions for the town’s expansive clay soils. Every subcontractor on your job meets our background-check and uniform standard, and Trevor Nash reviews progress weekly. General Contractor in Atherton
Bathroom Remodeling in Atherton
Bathroom remodeling in Atherton usually happens as part of a larger whole-home renovation rather than as a standalone project, given the town’s estate-scale properties. When we do tackle bathrooms, we’re working with architects of record who’ve specified Kohler, Grohe, or Toto fixtures, and we’re installing Cambria or Silestone surfaces that carry their own lifetime warranties alongside our 365-Day Done Right Promise. Moisture management matters here, too, with that seasonally high water table. Bathroom Remodeling in Atherton
Kitchen Remodeling in Atherton
Kitchen remodeling in Atherton means working within homes where the kitchen is often one of several, or where a single great-room kitchen anchors a 5,000-square-foot-plus floor plan. We install KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and we coordinate appliance specs with owner’s reps who expect zero deviation from the approved drawings. Our written price covers every cabinet, every pull, every linear foot of backsplash before demolition starts. Kitchen Remodeling in Atherton

Home Remodeling in Atherton
Home remodeling in Atherton demands a contractor who understands estate-scale logistics: heritage tree protection plans that can redraw your footprint, engineered foundations for expansive clay, and a building department that reviews every detail. We’re Penhallow Remodeling, and we deliver written prices and written guarantees before any work starts on your Atherton property.
Whole House Remodel
Signs you need it
Your 1960s ranch or traditional estate has good bones but dated systems, or you’ve purchased a teardown candidate and need to preserve enough structure to avoid triggering full new-build zoning scrutiny.
What it costs in Atherton
Whole house remodels in Atherton typically run $45,000 – $130,000 depending on square footage, structural complexity, and whether foundation upgrades are required for seismic compliance.
How we do it
We start with a structural assessment and soils report, then develop phased plans that keep you in residence where possible, pulling permits through Atherton’s building department and scheduling arborist monitoring before any exterior work begins.
Luxury Home Remodeling
Signs you need it
Your project involves architect-designed spaces, imported materials, or smart-home integration where the finish standard exceeds typical residential construction and requires a contractor accustomed to third-party inspection by owner’s reps.
What it costs in Atherton
Luxury home remodeling in Atherton starts around $75,000 and can exceed $130,000 for extensive estates with custom millwork, imported stone, and integrated automation systems.
How we do it
We hold pre-construction meetings with your architect and owner’s representative, establish sign-off protocols for every material sample and mockup, and assign a dedicated project manager who reports weekly and maintains the clean job site standard The Kingswell Way requires.
What Home Remodeling Costs in Atherton
| Item | Typical range in Atherton |

| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
How long does a whole house remodel take in Atherton?
Most whole house remodels in Atherton take 4 to 8 months from permit approval to final walkthrough, with heritage tree protection plans and engineered foundation work adding 3 to 6 weeks to the pre-construction phase. Call (936) 259-2607 and we’ll outline a realistic timeline for your specific property.
Do you handle permits and tree protection plans?
Yes, we pull all permits through Atherton’s building department and coordinate with certified arborists to develop town-approved tree protection plans before breaking ground, because a stop-work order for an unprotected Valley Oak can derail a project for weeks. Call (936) 259-2607 to discuss your site’s specific requirements.

We specify and install materials from recognized trade brands that back our 365-Day Done Right Promise with their own warranties: KraftMaid and Wellborn cabinetry, Cambria, Silestone and Caesarstone countertops, Kohler, Moen, Blanco, Delta, Toto and Grohe fixtures, James Hardie siding, and Therma-Tru doors. For ADU and estate expansion projects, we’re also experienced with modular and prefab systems from Abodu, Cover, and Dvele. Most standard items are available through our Peninsula suppliers with 2-week turnaround; custom orders extend lead times accordingly. See our brands for the full list.
