Yes, we can help. We start with a thorough plumbing inspection and drain cleaning to address the immediate clog. For Oakland residents, it's common for isolated clogs to be symptoms of older, stressed sewer lines. If a deeper problem is found, our trenchless sewer repair technology allows us to fix or replace damaged lines with minimal disruption to your property—a valuable service for many local homes.

We offer complete water heater installation and replacement, including efficient tankless models. As a licensed contractor with decades of experience, we assess your home's needs and hot water usage to recommend a reliable solution. We install quality products and handle all permits and code requirements for Alameda County, ensuring a safe and proper installation.
