Who we are

Exceptional construction, built the right way.

Alder & Stone is a design-build general contractor working on homes across Marin and the North Bay. We plan the structure, the systems, and the finishes as one job, so nothing gets decided in a hurry on site.

One project lead stays with you from the first walk of the lot to the final punch list. You get a fixed schedule you can see, a budget you can follow line by line, and crews who treat your street like their own.

What we do

Services built for North Bay homes

The hard jobs

We build where others won't.

Steep lots, unstable soil, and tight access are where a lot of builders bow out. We bring the geotechnical and structural engineers in early, then set drilled piers, grade beams, and retaining systems that carry a house on ground that wants to move. The hillside becomes the best seat in the house instead of the reason it never got built.

  • Drilled piers and grade beams
  • Retaining and drainage systems
  • Cantilevers and steel framing

Why homeowners choose us

Reasons homeowners choose us

  1. One lead, start to finish

    The person who walks your lot on day one is the person handing you the keys.

  2. Budgets you can read

    Every line is itemized up front, and changes are priced in writing before any work starts.

  3. Schedules that hold

    You get a week-by-week plan, and a short update every Friday on where it stands.

  4. Engineers in early

    Structural and soils engineers review the site before design locks, not after the first surprise.

  5. Our own crews

    Framing, concrete, and finish carpentry are done by people on our payroll, not a rotating cast.

  6. A clean site, every day

    Swept, secured, and quiet by evening, because your neighbors live there too.

In their words

They found a spring under our lot that two other builders missed, redesigned the foundation around it, and still finished the week they promised.
