Kitchen and Bath Works Inc has been owner operated and successfully in business since 1994. Offering a consultative approach and delivering on quality, custom work, our business has been overwhelmingly driven by word of mouth referrals. From start to finish, we stand by our work and our owner is committed to being present on all jobs.

"Lou renovated my kitchen last year and I was completely satisfied. I called him back this summer to gut and remodel my bathroom. He was extremely considerate, and he treated my house as if it were his own. My house is small, and I only have one bathroom. The project took nine days. I was anticipating that there would be a big mess and a huge inconvenience. But even the demo was done very neatly and efficiently. Lou even took the time to re-connect the toilet each night so that I wouldn't be left without. Lou did an amazing job, and it was a pleasure working with him. Once again, I am pleased to recommend Lou for your kitchen or bath project."

FAQs for tankless water heater installation projects in Rocky Point, NY

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.
