Landscape Service Areas Across Napa, CA and Beyond
Keystone Yards works across eight counties, each with its own primary city and surrounding communities. Napa County is the original market and still where most projects happen, but Contra Costa, Marin, Sonoma, Solano, Alameda, Santa Clara, and San Mateo counties have each grown into full markets of their own rather than occasional side trips outside a core service area. Below is the full breakdown by county, with a page for each city linked so you can see local details specific to where you live.

If your city isn't listed here, it's worth a call, service areas sometimes extend slightly beyond what's listed, and our team can tell you directly whether your address is covered rather than assuming based on a zip code alone.
What Stays the Same in Every City Keystone Yards Serves
Location changes the terrain, the climate, and the specifics of a project, but it doesn't change how Keystone Yards operates. Here's what stays consistent no matter which of the cities your property falls in:
Homeowners Across Eight Counties Trust Keystone Yards
Keystone Yards holds five-star ratings on Google, Yelp, and Facebook, along with Better Business Bureau accreditation and a Houzz profile. That reputation isn't limited to one city, it's built from projects across Napa, Contra Costa, Marin, Sonoma, Solano, Alameda, Santa Clara, and San Mateo counties alike, so the trust signals you see here reflect the whole service area, not just the home market.
Our Guarantee, Every City
Every project across all 80 cities Keystone Yards serves is backed by our workmanship guarantee, in writing. Location doesn't change the coverage, a project in Novato is backed the same way as one in Napa.
If an issue comes up, the process is the same regardless of which city the project is in: you call, describe the problem, and our team schedules a time to come take a look. There's no separate process for homeowners further from Napa, and no reduced coverage for cities at the edge of the service area.
Building Across Eight Very Different Counties
A hillside property in St. Helena, a flat suburban lot in Walnut Creek, a coastal-influenced yard in Marin County, a wine country lot in Sonoma, and a Peninsula estate in Atherton all call for different design and construction decisions. Keystone Yards treats each property according to its actual terrain, soil, and climate, rather than applying one regional approach across eight counties that don't behave the same way.
That local knowledge shows up in specifics: drainage plans that account for hillside grading in Napa County's wine country towns, planting choices suited to Marin's cooler, foggier microclimates, material selections that hold up under Contra Costa's hotter inland summers, and irrigation planning suited to Sonoma's own dry summers and varied terrain, on top of the different soil and climate conditions found from the East Bay through the Peninsula and South Bay. None of that comes from a generic playbook, it comes from actually building across all eight counties on a regular basis.
