What Marin Homeowners Face
The Problems We Solve
Permit Delays & Compliance Surprises
Marin County's 11 independent building departments each operate on different timelines and review standards. One incomplete submission can add months — and most contractors don't warn you.
Budget Uncertainty & Hidden Costs
Most contractors quote low to win the job, then escalate with change orders once demolition begins. A fixed-scope contract with line-item pricing eliminates that dynamic entirely.
Contractor Reliability & Project Timelines
Finding a contractor who shows up daily, communicates proactively, and delivers what was promised is harder than it should be in this market. Owner-led oversight changes that equation.

What Our Clients Say
“
Paulo was very professional, personable, and communicative — difficult to find with a general contractor. His team arrived promptly every morning, completed all the work quickly, on budget, and with very high quality. I highly recommend Paulo and his team.

Paulo and his team did a great job. The end result looks better than I was expecting — very clean, efficient, and professional. They came right on time and finished in the amount of time they promised. High quality work at a very reasonable price.

We interviewed several companies and went with our gut and chose ConstruBay. They were professional, on-time, and did a great job. So glad we chose them.
