Choosing a Peninsula Remodeling Contractor
Updated September 16, 2026.
Choosing a remodeling contractor means choosing the team that will interpret your goals, make technical decisions, and work through the details of your home. The strongest comparison combines relevant completed work, verified credentials, a clear scope, and a communication process you understand.
1. Look for work that resembles your scope
A portfolio should show more than a finish style you like. Ask what the contractor actually provided and whether the project involved the kind of work you are planning: structural changes, a whole-home renovation, an addition, or ground-up construction.
For example, BG’s Contemporary San Mateo Remodel included a complete four-bedroom, three-bathroom renovation with new plumbing and electrical systems. The Warwick Street project combined an expansion with a complete renovation. Those scopes raise different questions from a kitchen renovation within an existing footprint.
2. Verify the credentials and the team’s actual roles
Check the contractor’s license through the California Contractors State License Board. Ask who is responsible for design, engineering, construction drawings, permit coordination, and work on site. Clarify which services are provided by the firm and which involve outside consultants.
BG Design Build is led by Bahman Ghassemzadeh, a Cal Poly Architectural Engineering graduate with a minor in Construction Management. His California Professional Engineer license, Civil Engineer C-75941, was issued January 11, 2010; contractor license 982312 was first issued March 26, 2013.
3. Compare the written scope before comparing the total
Two proposals are useful to compare only when you understand their assumptions. Ask each team to identify the drawings and selections used for pricing, then review the same categories across proposals:
Demolition, debris removal, and site protection
Structural work and required investigation of existing conditions
Plumbing, electrical, mechanical, and utility work
Cabinetry, fixtures, surfaces, and installation
Permit coordination, inspections, and consultant responsibilities
Allowances, exclusions, and work purchased directly by the owner
Ask how changes are documented and approved before the work proceeds. For a budgeting worksheet and examples of different project scopes, see our Bay Area remodeling cost guide.
4. Ask how design decisions become buildable details
If you want to open a wall, vault a ceiling, add a story, or substantially change the layout, ask how the team will evaluate the existing structure and coordinate the necessary drawings. Attractive renderings are only one part of the work.
An integrated design-build process brings construction knowledge into the design conversation. The practical benefit depends on how the team coordinates responsibilities, decisions, and the information passed to the trades.
5. Make communication specific
Ask who your regular point of contact will be, how progress is communicated, and how questions about cost, selections, or schedule are resolved. Discuss how you will receive change proposals and how approvals are recorded.
Client feedback is most useful when it addresses those experiences. On our client reviews page, selected excerpts link to both the original review source and the related BG project.
6. Discuss the schedule and the realities of living through the work
Separate design and approvals from construction. Ask which materials or decisions could affect the sequence, how the site will be protected, and whether the proposed scope can reasonably be completed while you remain at home.
BG’s Hillsborough Kitchen Remodel was completed in two months, but that is the result of a particular project. Your schedule should be developed around your property, scope, approvals, and selections.
7. Choose a team you can assess clearly
Look for specific answers, relevant completed work, and a proposal whose assumptions you can follow. A productive first meeting should help you understand what is known, what still needs investigation, and what the next step will accomplish.
