Our reputation is based on service, safety, and quality, regardless of how large or small the job.

" I recently had the pleasure of working with Authority Plumbing, and I cannot recommend them highly enough. From the outset, they came to my home with a plan that demonstrated their deep understanding of plumbing challenges. Clayton, the technician assigned to my project, was exceptional. He took the time to listen to my concerns and opinions, making sure that I felt heard and valued. He explained each step, ensuring I was comfortable with the plan before proceeding. When a sub-contractor was brought on to streamline the process started making several errors, Clayton quickly took charge of the situation. They fixed these mistakes, alongside resolving my initial drainage issues, at no additional expense, was truly remarkable. The team demonstrated a genuine commitment to ensuring the work was completed to the highest standard. Thanks to their efforts, my plumbing issues have been resolved. I would not hesitate to recommend them to anyone in need of professional plumbing services. "

Please see our Special Offers and Promotions, for a limited time only! We service the San Gabriel valley. Owner Jeff Seale has been in the construction field since 1989. When he was starting out, he witnessed other contractors who were not focused on customer service. They either didn't complete the work correctly or they charged customers for work that was unnecessary. Jeff believed that customers deserved service that was both dependable and professional. Accurate, born out of the need for committed excellence and communication. We pride ourselves on an outstanding record of quality service. Our experience is testament to the level of service and quality you'll get when you choose Accurate for your plumbing needs. We have a staff of highly talented and motivated individuals that are eager to help you with all of your needs. We are excited you have expressed an interest in our services! We look forward to working with you.

"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."
