FAQs About Landscape Design in Napa, CA

Keystone Yards works across Napa, Sonoma, Marin, Solano, Contra Costa, Santa Clara, San Mateo, and Alameda counties. If your city isn't listed, it's still worth a call, our team can tell you directly whether your address falls inside the service area.

Project cost ranges widely, from around $40,000 to $1,000,000, depending on scope, materials, and how many trades a project touches. Our team gives you a real number based on an actual site visit, not a rough estimate over the phone.

That's normal. Some homeowners come in with a clear plan, others just know their current yard isn't working for them. Either way, our design team walks you through the options and helps shape a plan around how you actually want to use the space.

Keystone Building Inc. holds CA License #1078372, covering General Building and C27 Landscaping. You can verify it directly on the California licensing website before you even pick up the phone.

Most of the work is handled in-house by the Keystone Yards crew. Specialized trades like gas line and electrical work are the exception, since those require their own licensed specialists, but they're coordinated as part of the same project rather than handed off separately.

A dedicated crew works your project through to completion, with one foreman assigned to keep the schedule and the work itself on track. You're not sharing a crew that's splitting time across several other job sites at once.

Most projects start about 6 to 8 weeks after the contract is signed, though weather and material availability can shift that timeline. Our team gives you a realistic window based on your specific project during the estimate.

No. Keystone Yards works on residential yards as well as commercial properties, including wineries and office parks, throughout the service area.

Keystone Yards builds everything from contemporary and modern designs to traditional and Mediterranean-inspired landscapes. The style follows the property and what the homeowner actually wants, not a single house look applied to every yard.

Site conditions sometimes turn up something that wasn't visible before construction started, a drainage issue, a utility line, unstable soil. When that happens, our team talks through it with you directly and adjusts the plan together rather than making the call unilaterally and presenting it as a done deal.

Ongoing lawn and landscape maintenance isn't something Keystone Yards offers, since the company is built around design-build projects rather than recurring service visits. Our team can point you toward a maintenance contractor to keep the finished landscape looking the way it did on walkthrough day.

Crews follow standard jobsite protection practices, covering and staging materials carefully and keeping equipment and debris contained to the work area, so the rest of your property stays usable while construction is underway.

Just Keystone Yards, the whole way through. The same team that draws up the plan is the one that builds it, so you're not coordinating between a design firm and a separate contractor.

Yes, in writing: every project is backed by our workmanship guarantee, regardless of size. If something built by Keystone Yards has a problem, someone comes back and fixes it.

The estimate comes from an actual walkthrough of your property, rather than a square-footage calculation done over the phone.

Yes, the portfolio page has completed projects with before-and-after photos and video.

There's no hard minimum, though Keystone Yards is set up for full-scope design-build projects rather than small, one-off repairs like patching a single paver or fixing a fence board.

Your assigned foreman keeps the schedule and the work on track day to day, and our team stays involved for anything that needs a decision, so you're never waiting days to find out what's actually happening on your property.

Grading, retaining walls, and major drainage changes often require permits in Napa and surrounding counties. Our team factors permitting requirements into the plan from the start so it doesn't turn into a delay once construction is underway.

Rain and other weather can push a schedule back, especially during grading or concrete work. Our team builds a realistic timeline around this upfront and keeps you updated if conditions push a phase of the project back.

Small adjustments are usually workable, but bigger changes can affect both the timeline and the cost. Our team talks through what's realistic once a change comes up, rather than just building around it and surprising you with the impact later.

That depends entirely on scope. A single patio or fire pit might wrap in about a week, while a full backyard rebuild touching every trade takes considerably longer. Our team gives you a project-specific timeline during the estimate, not a generic range.

No. Keystone Yards builds commercial landscape design and construction projects, like wineries and office parks, but HOA contracts and ongoing maintenance accounts pull attention in a different direction and aren't something the company takes on.

Swimming pools and ongoing lawn or landscape maintenance are both outside the scope. If your project falls into either category, our team can usually point you toward someone who specializes in it.

Not for most of it, though our team likes homeowners to be reachable for the site visit, the design approval, and the final walkthrough. Day-to-day construction runs with the foreman on site.

The estimate is built from an actual site visit, so it holds unless something changes the scope, like a homeowner adding to the project or a site condition that wasn't visible until construction started. Either way, that gets discussed with you before it affects the price, not after.

Often, yes. Our team looks at what's already there during the site visit and talks through what's realistic for matching it versus starting with a different material or design direction.

Crews keep the work area contained and materials staged properly throughout construction, so the property stays usable and doesn't turn into a standing construction zone between work days.
