About the Company
Founded in 1910, Dimond Plumbing & Heating Co. has deep roots in the East Bay, originally serving families and businesses relocating after the 1906 earthquake from its home in Oakland's Dimond District. I started my career digging ditches at 17 and learned that the plumbing trade is about continuous learning—from code changes to new technologies. What we offer San Leandro is simple: a commitment to doing a good job at a fair price, a value we've upheld for generations. Our history includes significant projects for Alameda County and UC Berkeley, but our reputation is built on trust with local residents. Today, many of our customers are the children and grandchildren of those we first served, a testament to our focus on quality work, integrity, and reliable service for both homes and businesses.

Common Questions
My AC is blowing warm air and I'm worried about refrigerant leaks, which you mentioned are common here. Can you help?
Yes, absolutely. Refrigerant leaks are a frequent issue in San Leandro, often due to our climate and aging AC components. Our technicians are trained to safely locate and repair these leaks using precise detection methods. We'll also check the system's pressure and recharge it with the correct amount of refrigerant to restore efficient cooling. Addressing leaks promptly not only fixes your comfort but also prevents further damage to the compressor, helping your system last longer.
As a company founded in 1910, do you work on modern plumbing fixtures and water heaters?
Our long history is built on adapting and learning. While we've been in business since 1910, we stay current with all advancements in plumbing and heating technology. We regularly install and repair modern tankless water heaters, high-efficiency fixtures, and smart home plumbing systems. Our experience gives us the perspective to recommend reliable solutions, whether it's a classic repair or a new, efficient installation for your San Leandro home.
What does your plumbing inspection service involve, and when should I consider one?
Our thorough plumbing inspection is a proactive check of your home's entire system, including pipes, drains, water heaters, and fixtures. We recommend one before buying a home, if you're planning renovations, or if you have an older property in San Leandro. The inspection can identify minor leaks, corrosion, slow drains, or potential sewer line issues before they become major problems. It's a practical way to maintain your plumbing's health and avoid unexpected repairs.
