JAMISON PLUMBING INC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Yes, I hired this pro. I've been a general contractor for over 10 years, and this has been one of the most pleasant partnerships I’ve had with a plumbing subcontractor. They are highly responsive, technically proficient, and capable of handling everything from small plumbing issues to complex gas line setups. We’ve worked together on both a commercial renovation and a residential ADU project, with a combined project value of over $100,000. While their pricing is slightly above the market average, I believe their professionalism, reliability, and willingness to coordinate closely with my team absolutely justify it. There wasn't an exact category to describe the scope of our work here, but I would recommend them wholeheartedly for anyone seeking a trustworthy and capable plumber, especially in demanding or large-scale projects."

"From drab to fabulous! Eco home Builders did a fantastic job on my main bathroom remodel. I'm a Real Estate Broker and have gone through countless remodels and contractors over the past two decades. Eden did a wonderful job managing the project. Always communicating and being available through the whole project was a huge plus. The contractors did an outstanding job and really paid attention to detail. A lot of large tile pieces went into this project, and I was in very impressed with their skill. We were also impressed with their cabinet maker who did a great job basically building a beautiful piece of art. The project basically went off without a flaw on time and on budget. I would highly recommend Eco Home Builders to anyone thinking of doing any sort of remodel project, I rarely give reviews, but in this case, I felt it was necessary to give kudos that are well deserved. Thank you all for a wonderful job!"

The White Glove Guys are San Diego's BEST plumbing heating and AC service provider. We are passionate about providing homeowners with the safest, healthiest, most energy efficient and comfortable home. A San Diego staple since 1952. Financing available. License #: 513115. Additional email - Agia@Whitegloveguys.com Additional Contact - Agi Ambrezewicz

"Never again with ASI, the White Glove Guys I just went through a plumbing problem using ASI and will never use them again. My problem started when I could hear water running in a downstairs bathroom. And found that I had water leaking out at the base of the stucco siding behind the bathroom. I called ASI and they were able to send a plumber the next day. The plumber arrives and I explain the situation to him, and we agree that the best (least destructive) way to get to where we hear the leak is from the outside. He cuts an 18-inch square hole in the stucco so that we could see the leak. The good news is that we cut in exactly the right spot to see what was going on. The bad news is that the water was leaking from the sleeve surrounding a branch of the water line that went down into the concrete slab. He tells me he can’t fix the leak, but he will take the appropriate pictures and send them to the person at ASI who does leak detection and have him call me the next day. Cost for his 30 minute visit was $225 ($450 per hour!) and all I have to show for it is a hole in the side of my house. To be fair to the plumber, he didn’t know what he would find, and had the leak been above the slab he could have fixed it and we would have gone happily on our way. The next day comes and goes with no call from ASI, so I call them the following day. They can schedule me in for three days later. I’m thinking that the guy coming is going to locate the leak and fix it, but that’s not what happened. He looked at the problem and we discussed where the possible places where the leaking line could go to. We figure there are two likely places the line goes, one good and one bad. The most likely possibility is to the ice maker in the refrigerator which is in the middle of the slab with no easy way to get to it. The other is to a wet bar sink that was removed many years ago with the line water lines capped off. He says that if the leak is in the unused sink, the water line it will just be capped and it will just be a service call like before. If they have to reroute the water line will be a one-day job which is a fixed price of $2900. Considering that we think that they are going to have to run a line to an outlet in the middle of the slab, the price appeared reasonable, so we schedule for several days later. When the plumbers arrive to do the repair, the first thing is to cap off the leaking line and determine where this line actually goes. The good news is that it isn’t the ice maker, but it wasn’t the capped off wet bar sink either. Instead, this line goes to the kitchen sink. This was the best alternative possible as almost the entire rerouted line could be run outside the house. They proceed and you can see the result in the pictures. The long line on the house turns into the house though a hole they cut in the stucco and through one cabinet and has a shutoff valve on the end of it. On the near end was a down-over-up loop of about 18 inches total to connect to the water supply. They insisted on taking lunch at the point where they just had to solder one last joint. So, after the lunch break they take five minutes to solder the joint and turn on the water to check for leaks. They got here a little before 9 am and even after a 30 lunch, it is 11:30 when they are done. So even though they spend less than half a day running this one line, they still charged the full amount. I complained to the company but their argument is that they change a fix price to protect the customer if the job goes long. The problem is that if the job goes short because they estimated the job incorrectly, the customer does not get a break. In hindsight, the job should have been reevaluated once the true destination of the water line was known and done on a time and material basis. So, the bottom line is that I paid ASI over $3100 for a little over three hours work or about $1000 per hour. I will never use them again!"

The problem is that if the job goes short because they estimated the job incorrectly, the customer does not get a break. In hindsight, the job should have been reevaluated once the true destination of the water line was known and done on a time and material basis. So, the bottom line is that I paid ASI over $3100 for a little over three hours work or about $1000 per hour. I will never use them again!"

FAQs for tankless water heater installation projects in Cardiff By The Sea, CA

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
