Why JP Coastal Plumbing

One Plumber, Start to Finish

No rotating crew and no call center in between. The person who looks at the problem is the person who fixes it, which is why the explanation you get on site matches the work that actually happens.

  • You talk to the plumber doing the work, not a dispatcher
  • Options are laid out with the trade-offs, not just the priciest one
  • Older Central Coast homes and their surprises are familiar territory

Process

How a Job Goes

  1. Step 1

    Tell us what's happening

    A call or a short service request with the city and what the plumbing is doing.

  2. Step 2

    Look at it properly

    The fixture, heater or line gets inspected before anyone talks about a fix or a price.

  3. Step 3

    Do the work

    Once you approve the approach, the job gets finished and the area is left clean.

Water Heaters

Water Heater Repair and Replacement

No hot water, rusty water, a puddle at the base or a unit that has quietly reached the end of its life. The visit starts with whether the heater is worth repairing at all — sometimes it plainly is.

Water heater service

Water Treatment

Softeners and Whole-House Treatment

Scale on fixtures, spotting on glassware, appliances that wear out early. Treatment equipment is chosen around the property's plumbing and where it can realistically be installed.

Water treatment service
Puronics and Halo whole-house water treatment tanks installed alongside a water heater with copper supply piping.

What Customers Say

My old water softener system stopped working and based on a positive review I saw online, I contacted James Price of JP Coastal Plumbing. James came out promptly to assess the situation. After determining that repairing my existing system would not make economic sense, he recommended a new system. He provided me with three options at various price points. All quotes were fair and reasonable, and included all parts and full installation, including disposal of my old unit. I chose the best of the three options and within days, the equipment arrived (it had to be shipped from out of town) and was then installed. James took his time with installation and was meticulous in his installation. He also took time to explain what he was doing and why, to make sure I understood how things worked. I couldn't be more pleased. The system is working great and I highly recommend him.
Andrew Weiss

Sabrina Espinoz
James did a great job. Was on time, completed the work quickly and efficiently, very professional and conscientious. He'll let you know if he see what could be potential problems and will give you the reasons why and recommendations for repair yet hes not pushy. I have future projects for the house and James will be the first one I call.
Jerry Brodnick
I couldn't be happier with the service from JP Coastal Plumbing. James made the entire process easy and stress-free. He was respectful of our home, answered all of our questions, and made sure everything was installed correctly before he left. We definitely made the right choice and will be calling them again for any future plumbing projects.

James was straightforward about what was to be done and took time to explain it based on the evaluation he performed. He was very thorough and I could tell he took pride in his work. His work was of high quality. I would hire him again in a minute.

James rescued us when we found ourselves with a plumbing emergency on Saturday of Labor Day weekend. We called him and he picked up the phone, was at our house 20 minutes later and solved our problem within an hour. He came back the next week and fixed some plumbing in our master bath shower. James was reliable, competent and great to work with!
