"Let’s just say communication was stellar from the get-go! We met with Tom to go over what work we wanted to do and there’s just something about making a personal connection with someone that makes you feel confident that the work they’re going to do for you is going to be great, and it was! Can’t say enough about Tom and his brother Jesse‘s professionalism, knowledge and skill!! Along with countertops, we were also installing some unfinished cabinets and we didn’t even know it was an option, but Tom offered without us asking to prime and paint them for us as well, AND he even went and matched the paint so the new cabinets matched the old ones we were keeping, which was great because we were under a time crunch to get this work done before family was coming to stay with us. Tom and Jesse worked with us to make sure everything was completed and that we were 100% satisfied in the short amount of time they had to get it done for us. Everything looks beautiful and we would definitely work with Tom and Jesse again in the future! Actually, hoping to have them come back and do some laminate flooring for us as well! Highly recommend these guys, they are great guys, great communication, 100% trustworthy and I guarantee they will do a great job for you!"

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.
