At Roy's, we understand how stressful it is to lose plumbing, electrical, or heating and cooling comfort. And while we can't always prevent that stress from happening when those breakdowns first occur, we can give you a great experience that takes that stress away fast. Creating a worry-free service experience takes teamwork, resources, and skill. It also takes dedication from every technician, plumber, and customer service representative we have, all working with the same purpose: to make your repair or install as easy as possible, as quickly as possible. But it goes beyond good service. We're dedicated to giving back to our community, as well. Every month, our Roy's Cares program makes a $500 donation to a local charity, and each time a technician places a lawn sign at the end of a job well done, we donate $5 to another monthly charity recipient. It's just one way we dedicate ourselves to our city and the people in it, both in our business and beyond!

"Rep (Tyler) arrived on time. Was very personable and professional. Evaluated and completed repair quickly and without issue. I’m very happy with the results. (Note…Angi categorized project as a broken pipe when actual issue was wit an on demand water heater.)"

Cellino Plumbing, Inc., is a locally owned and operated plumbing company that has been servicing Western New York since 1995. If your toilet is plugged, we can fix it, If your sewer is backing up we can repair it. Is Drain running slow? No problem, we can clear it. We can do it all from whole house remodels to drain cleaning, sewer repair, toilet and faucet installation. For your convenience, most of our plumbing calls are completed in just one visit. That's because we feature a service truck that is really more of a rolling warehouse. Every truck is stocked with the same high-quality parts, supplies, state-of-the-art equipment and tools, to repair virtually anything on the spot. Give us a call today!

"I’m reluctant to leave a negative review, but my recent experience with Cellino has left me no choice. I initially hired Cellino for a greenhouse HVAC project, based on a positive recommendation and previous great service with a furnace issue. On September 6, Chris came out to assess the job, spending significant time taking measurements and photos, and assured me they had handled similar projects. After weeks of visits and reassurances, we received a quote on September 18. Though it was higher than others, I trusted Cellino based on their professionalism. However, on October 22, over a month later and after multiple assessments, the installation team informed me that the heater they specified was actually overpowered for our greenhouse—news that should have been caught early on. This oversight led to weeks of back-and-forth exchanges, ending with us exchanging the heater for a more suitable model. This delay has cost my business thousands in lost stock due to inadequate heating."

Cellino Plumbing is a professional, fast responding plumbing company. Our expert plumbers serve all of the West New York area. Call us today!

"Terrible, technician left and I still had a leaky sink. Said that I would have to make another appt. “Bullied” me into getting a $800.00 garbage disposal two months prior to avoid pipes clogging, two months later, same clogging !!! Technician went in my basement and told me I needed a new sump pump. Cellino is trying to get as much money from me as they can, without finishing their repair work. Never again. Horrible customer service and technicians have absolutely no idea what they are doing."

"We recently hired PR Carpentry to build a new deck, and we couldn't be happier with the results! From the initial consultation through project completion, the team was professional, responsive, and highly skilled. They took the time to understand exactly what we wanted, offered helpful suggestions to improve the design, and delivered a finished product that exceeded our expectations. The quality of the craftsmanship is outstanding — every board is perfectly placed, and the attention to detail really shows. The crew showed up on time every day, kept the worksite clean, and were respectful throughout the entire project. They also stayed on schedule and within budget, which we really appreciated.

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.
