"Italish Remoldling and Custom Cabinets is a great company if you need any remodeling done. They did a complete remodeling of two bathrooms which included taking out a sunken tub and making a walk-in shower in master bathroom and installing a pocket door. In guest bathroom they add a shower to current bath tub. Made all new cabinets for both bathrooms to our expectations. They updated our kitchen cabinets by making new soft close cabinet door fronts and new soft close drawers They installed new doors throughout our house including new front door, garage door, kitchen fire door, all bedrooms, and bathroom doors. Installed new flooring in our living room. Everything turned out beautifully. Every detail we asked from Rodney and his crew, they made it work. I would recommend this company to anyone. They are quick, reliable, a great team of professionals. Rodney is a great source of information. He had lots of connections to other contractors to help complete our remodeling needs. He followed up with outside contractors to make sure the job they were working on was done correctly. If I need anything else done, this company will be my first call."

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.
