You will lead estimates from initial plan review through final pricing, working directly with ownership, our design and drafting team, project managers, and subcontractors to build budgets, coordinate pricing, and catch scope gaps before construction begins. At least 3 years of construction estimating experience or equivalent construction experience is required.

Who You Are:

You bring at least 3 years of construction estimating experience or equivalent relevant construction experience. You understand residential construction and remodeling methods, materials, and labor requirements. You read architectural, structural, and construction drawings with confidence and turn them into detailed estimates and material takeoffs. You know how subcontractor bidding works and can spot gaps, exclusions, and conflicts in a proposal. You are highly organized and detail-oriented, comfortable with spreadsheets and estimating software, and able to manage multiple deadlines. You communicate proactively and value realistic, complete estimates over rushed or artificially low pricing.

Who We Are:

We are a family-owned general contracting and custom millwork company in San Rafael, founded by brothers Jacob and Eli Froneberger. We build custom homes, renovations, additions, ADUs, commercial improvements, and architectural millwork across Marin County, San Francisco, and the North Bay. We take pride in thoughtful planning, quality craftsmanship, transparent communication, and strong relationships with clients and trade partners.

What You Will Do Each Day:

Review plans and perform quantity takeoffs to build labor, material, equipment, and subcontractor cost projections. Prepare preliminary budgets, conceptual estimates, and detailed construction proposals with clear allowances, assumptions, and exclusions. Build and send bid packages, collect competitive pricing, and compare subcontractor proposals side by side. Work with designers, drafters, project managers, and ownership to resolve missing or conflicting information. Join site visits and preconstruction meetings to flag cost risks and find value engineering opportunities. Hand off organized estimating packages to the field and review actual costs against estimates to sharpen accuracy.

Why You'll Love Working Here:

Pay is $53 to $70 an hour based on experience. Work directly with company ownership as you learn our estimating systems. Optional remote hours after training and development. Diverse and challenging residential and commercial projects. Real room to grow into an independent, trusted estimating lead.
