Signature Plumbing

Signature Plumbing runs as a family-owned plumbing outfit out of Rocklin, California, with roots back to 1993. They take on water heaters, drain cleaning, sewer repairs, hydro jetting, and general fixes across Lincoln, Roseville, and nearby spots in Placer and Sacramento counties. Jim serves as owner and leads jobs with Jay and others like Randy, Seth, James, and Clancy. The crew stays licensed and insured under number 1153177, offers 24/7 emergency calls, and handles both homes and businesses with same-day options when needed.

Homeowners describe fixes for sudden flooding after time away, kitchen faucet swaps that leave everything working right, long clogs at businesses that required hours of work, leaking water heaters replaced the same morning, and sewer line inspections with video proof for new owners. Randy got one flooded home sorted fast after a vacation, Jim and Jay swapped out a bad water heater unit in one day, and the team cleared a tough clog while sending updates throughout. Reviewers note they solved a kitchen hot water delay that had stumped others for years, and they completed thorough checks on minor and major issues without pushing extra work.

The outfit shows up on time, answers texts with photos and quick replies, and keeps pricing straight with no surprise add-ons. Customers in Rocklin and surrounding towns mention responsive office staff who fit jobs into the schedule fast, work past regular hours when hot water or leaks hit on weekends, and finish with clean job sites. Service stretches to Loomis and other local areas, with honest quotes that match the final bill every time.

“Highly recommend signature plumbing. Cannot say enough good things. The communication was PHENEMONAL! Seth did an awesome job getting us all set up and ready to go on their schedule very quickly when we came home to some flooding after a weekend vacation. Randy was our plumber and he was awesome! Very friendly, explained things very thorough, and completed the job quickly. Even ensured that everything was working well beyond expectations after completion. The company is very honest and upfront about their project expectations, cost, and doesn’t try to constantly upsell you. It does not feel like your typical “sales tactic” environment. It feels that the company geniunely just wants what’s best for the people they provide services to! So glad we worked with them!”

“I had a great experience with this plumbing company. They replaced my kitchen faucet and did an excellent job. The plumber arrived on time, was professional, and completed the work efficiently. The installation looks great, and everything is working perfectly. One thing I especially appreciated was that they were available via text message. It made communication very easy, and I was able to quickly send pictures of the faucet without having to deal with phone calls or emails. The entire process was convenient, straightforward, and stress-free. I appreciate the quality of the work and the excellent customer service. I would definitely recommend them to anyone looking for reliable plumbing services.”

“I've been a customer with Signature Plumbing for a few years now for both minor and major issues in my home. Jay and James are amazing- they are reliable, honest, and very thorough. I refuse to trust any other plumbing company and always go straight to them when I have a problem and I know they are going to figure it out quickly and at a reasonable cost. Their office staff is very responsive and accommodating as well!”

“This company was attentive, prompt and really does know what they’re doing! For years I could not get hot water from my kitchen faucet until I ran water for up to eight minutes. Other plumbers would say you’d have to do this complicated thing and it would be expensive. Signature plumbing said no way we can fix that. It’s easy! I now have the hot water instantaneously and I couldn’t be happier! They were clean and courteous, and I would definitely call them again.”

“Oh my word!!!! I would give Jim a billion stars if I could!!!!! I have a plumber I can trust!!! That means everything to have someone kind, knowledgeable, fair prices and easy to work with!!! He came after normal hours so I could have hot water finally. It went out Friday. I called my home warranty company. That was extremely frustrating and their plumbing company didn't return any calls until noon today. Their reviews were not very good either. Signature Plumbing is top notch!!! You will not have any problems! They arrived early, and same day service!!! Just unbelievably awesome!!!!!! I will happily refer friends and family without any qualms at all!!!!!”

“I’ve had consistently great experiences with Signature Plumbing. I’ve called them multiple times, and they always make the effort to fit me into their schedule quickly. Each time, they’ve been thorough, professional, and reliable in handling my plumbing issues. Their repair costs have also been fair, which I really appreciate. I highly recommend them for anyone needing dependable plumbing services.”

“I've used Signature Plumbing for many years and I wouldn't call anyone else. I called Jim last night for a leaking water heater and he arrived at 7:30 this morning. The problem was a defective 3-week old water heater. Jim returned later in the day with his partner Jay to install a new water heater. They got the job done! Thank you Jim and Jay you are the best. So thankful you guys are around.”

“Jim and Jay are the absolute BEST plumbers! Jim, the owner, is a clear communicator, trustworthy and thorough. He came out to clear a bad clog at my business, which took 7 hours to get done it was so bad and came with so many challenges. Jim kept me updated every step of the way. I was surprised and relieved when I recieved my bill and it was less than I expected. These guys are worth their weight in gold. If you are looking for someone honest and reliable, look no further than Signature.”

“Extremely impressed with the promptness and ease of service. In addition Signature Plumbing charged me what they quoted. I recently had a Home Depot installation at another place with a $1,000 upcharge. I will only use Signature in the future.”

“I needed an inspection at my new home in Loomis. These guys are amazing, the new owner Clancy was so helpful today, and their response time was the best i've ever experienced. The tech that came out to do a lateral sewer inspection was great and showed me the video he recorded, I will definitely be calling again for all my plumbing need. Highly reccomend!”
