We are a locally owned and operated company that values honesty and integrity, and treats your home as if it were our own. Our only priority is to provide the highest level of customer service. We know that plumbing emergencies are enough of a headache without dealing with an ornery customer service rep or repairman. We offer a warm voice, a courteous call, and a convenient process. We make your emergency a priority for us, scheduling service as quickly as possible to resolve your problem. Our plumbers are the same way—they treat your home with respect and consideration. We wipe our feet on our own mats, we wear shoe covers before entering your home, and we’ll offer you a fair assessment of your plumbing situation and how much it will cost to handle it. Our prices are flat-rate and upfront, so you don’t have to worry about inflating prices as the job goes on.

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."

"The installation was very efficient and the crew did an excellent job in regards to the plumbing hookups and testing. I highly recommend this company and would use them for future projects.

*Please Call Directly* WE SPECIALIZE IN COMPLETE REMODELING PROJECTS WITH A MINIMUM COST OF $5,000. We are a team of skilled craftsmen each with many years of experience remodeling kitchens and baths in the Orange County area. At Coastal Kitchens Inc. instead of a showroom we use door style, finish and kitchen cabinet samples, as well as photo design books and CAD on laptops to display your kitchen as it is designed. This way we eliminate the need and the cost associated with a showroom business model. This makes the design process more convenient for our customers, and we pass the significant savings on to them as well. Our design process also allows us to spend more time working on our customer’s designs. This is what we enjoy most about our business and it is what makes the difference between an average and a great kitchen design. Why should I work with Coastal Kitchens Inc.? John (the owner) has 34 years of experience in the remodeling field along with his experienced team. Our top priority is ensuring you receive the highest value for your dollars. This means we will sometimes suggest less expensive options for some aspects of your kitchen to accommodate better investments for others. For example, we can often recommend a cabinet door style that will appear identical and cost substantially less leaving you more dollars for your overall renovation. One of our guiding principles at Coastal Kitchens Inc. is that the best investment in your kitchen is always your design first and your door style second. Exceeding expectations, but never your budget. Contact us through email at coastalkitchens@cox.net for faster response. Credit card purchases are welcome however we charge a small convenience fee.

"BEWARE OF COASTAL KITCHENS & BATHS! This review is for a complete remodel of our master bathroom that occurred in early 2024. This business has no BBB rating. This business has no employees. This business has no presence on Houzz, Angi.com, Home Advisor, Yelp or any place else online and no website. Everyone who works for John Bailey is a sub-contractor. His subs vary widely in quality. Some are good and some are not. His idiot painter tracked white paint all over our master bedroom carpet. When I complained to John about that he responded that we were going to replace the carpet anyway and so what! His sub-contractors had to access the bathroom by going through our master bedroom. THEY DIDN'T EVEN PUT DOWN DROP CLOTHs. When I complained to John about that he had them put down tarps that were so filthy that it made our floors even worse than before. When it came time to install the vanity countertop the supplier (Best Cheer Stone) delivered the wrong countertop and John didn't even notice! My wife caught the mistake. John pressured us into accepting the mistake by telling us there would be a 2-3 week delay in the project if we insisted on returning the countertop. He did get us a discount from the supplier but it’s still the wrong countertop. Recently I noticed that one of the bathroom floor tiles had cracked only 10 months after installation so I called John to see if he would replace it. He told me he would talk to his tile guy and get back to me. A week later still no response so I called him back. He clearly did not want to accept responsibility and told me that replacing the tile might damage other tiles. This is nonsense because I have had 3 tile contractors look at the job and none of them said anything about that. When I tried to get John to accept responsibility for the cracked tile he got mad and hung up on me! BEWARE OF COASTAL KITCHENS & BATHS! John Bailey is super sketchy and will blow smoke at you all day long to get your money. He does not guarantee the work and will leave you with a $600 extra charge for tile replacement. I have other complaints too but in the interest of brevity I will stop here."

Tankless water heater installations FAQs

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.
