We are a kitchens and bathrooms company. We specialize in custom showers, custom cabinets and counter tops. We staff high end professionals and use sub contractors only when necessary. We also give a very detailed estimate, action oriented so you only pay for the work preformed and gives control to the homeowner.

"These guys were fantastic. They are one of the few companies out there that that actually do what they say will do. They send you daily emails around 830 am describing the activities for the day and who will be inside your house. Their communication is great - they always answer emails and texts in a very timely matter. The master bathroom we had remodeled looks great and was done in the time period they indicated at the beginning of the process. Sure, you could probably find someone cheaper and does inferior work, however we wanted it done right the first time. Nic and Sarah and the entire team exceeded our expectations!"

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.
