Get matched with top storm drain installation pros in Diamond Bar, CA

"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"Response was amazing and fast. Arrived on time and kept me fully informed. Professional with complete set of moisture/ leak detection tools. Answered all our questions. Would love to recommend them."

"Wesley was fantastic! We were hoping to be able to extend the gas line from the fireplace to the stove but the piping was too small there to accommodate the stove we purchased. While he said it could be done, and was significantly less expensive, it may not be able to provide the 'power' the stove required. We chose to do it the right way, not the 'cheap' way, pricing was still reasonable for the amount of work that needed to be done. Highly recommended!!"

"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"⭐️⭐️⭐️⭐️⭐️ Outstanding Service, Integrity, and Communication We had SoCal 1 Plumbing & Rooter handle a job on our exterior drain pipes, and the experience exceeded our expectations from start to finish. Not only was the work itself done extremely well, but what truly set this company apart was their professionalism, transparency, and genuine care for us as homeowners. Their executive manager, Shane, was personally on site to diagnose the issue, provide a in depth explanation, organize his crew, and ensure everything was handled correctly. He even returned to confirm that the job was completed properly. Having direct access to a manager who was knowledgeable, responsive, and willing to answer questions made a stressful situation feel completely manageable. I could call Shane at any point to bounce questions off of him, and every recommendation was explained thoroughly and honestly. They took the time to help us understand the severity of the problem, and exactly whats needed to fix"
