With all the new health concerns caused by COVID-19 we at Professional Plumbing Inc have increased our efforts to make sure we help stop the spread of this virus. All our technicians are now wearing a new set of gloves and booties into each home. All tools are wiped down with wipes made to kill germs, not just clean them before going back into the trucks. Hand tools are periodically dipped in rubbing alcohol to further help destroy germs. These may seem like extreme measures, but we take your health and the health of all our employees seriously. Thank you for your continued business. We are not the typical plumbers, our guys are neat and clean, well groomed, respectful of you and your property. They arrive in a clean truck that is well stocked, and best of all we don't try to charge you a ridiculous amount of money to do a so-so job. Minor plumbing leaks to replacing the sewer line in you front yard. We can handle any plumbing issue you have quickly and we are affordable. We are here to help. We want your business and it shows on every job we do. We come in and quickly solve your plumbing issues, then we clean up so well that you can't really tell that we were even there, except of course, your plumbing is working the way it is supposed to. Try us once and you will wonder why you haven't used us in the past and you'll want to use us in the future. Additional phone - (949) 646-5511, (877) 755-3519.

Boiler repairs FAQs

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
