"Matt at Grit Builders, LLC was the best contractor we have ever worked with. We came to him with two bathroom remodels which we needed to be done before selling our house. From the first conversation with him, I knew he was going to be true to his word on completion, budget, and communication throughout the project. We had a pretty tight timeline which he meet and came in at budget / cost. He and his team were communicative, hard working, and clean throughout the entire process. The result was amazing and added the refresh to a 20 year old house which we were looking for. We had cabinetry repainted, new shower / bath stalls installed with tiled walls. Complete reflooring as well as new countertops, vanities and mirrors. He also helped clean up other smaller projects within the house which we wanted addressed before listing our house."

FAQs for tankless water heater installation projects in Lake Oswego, OR
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.
