Question Answers

As a San Francisco homeowner, can you handle both my bathroom remodel and the plumbing updates it needs?

Absolutely. Our dual licensure as a General Contractor (B) and Plumbing Contractor (C-16) is a key advantage for Bay Area projects. This means our team can manage the entire scope of your bathroom remodel—from structural changes and tile work to installing new showers, bathtubs, faucets, and toilets—without needing to coordinate separate subcontractors. We ensure all plumbing is correctly integrated into the new design, saving you time, simplifying communication, and providing a single point of accountability.

We're considering building an ADU in San Mateo County. What does the process with Cai Construction involve?

Building an Accessory Dwelling Unit (ADU) involves several key steps we guide you through. It starts with a consultation to understand your goals for the space, followed by our construction design services to create plans that meet local zoning and building codes. As licensed general contractors, we then manage the entire construction process—from foundation work and framing to plumbing, electrical, and interior finishes. We handle permitting, provide a detailed timeline, and maintain clear communication throughout, ensuring your new guest house or rental unit is built efficiently and to code.

My water heater in San Francisco isn't working as well as it used to. Could it be sediment buildup, and can you fix it?

Yes, sediment buildup in water heaters is a common issue in our area due to local water mineral content. It reduces efficiency, can cause strange noises, and shortens the unit's lifespan. We offer thorough plumbing inspections to diagnose this. Our service includes flushing the tank to remove sediment and assessing the unit's overall condition. If repair isn't viable, we provide expert water heater installation or replacement. Addressing this proactively can restore hot water performance and help prevent more costly problems down the line.
