"Exceptional Service from Kelsey Asrouch – Highly Recommended! We had the pleasure of working with Kelsey Asrouch, a plumber from Hart’s Services, and the experience was outstanding from start to finish. Kelsey installed three new toilets and cleared a stubborn clog in our kitchen sink air gap—and he did it all with incredible professionalism and skill. He arrived right on time, fully prepared, and walked us through everything he was going to do. His attention to detail was impressive, and he made sure everything was functioning perfectly before he wrapped up. On top of that, he left the work areas spotless—you’d never know a major plumbing job had just taken place. Kelsey was also courteous, respectful, and communicative, making the whole process smooth and stress-free.

"Intrepid did an incredible job in a time that we really had an emergency. They had our water heater diagnosed and replaced luckily within 24 hours. On top of the urgency that we needed a replacement, the price was really fair. Robert did a great job and was very friendly and professional while working at my house. They left no mess and removed the old water heater. 10/10 would use again"

"Terrible service and experience. AVOID. UNRELIABLE. SCAMMERS. They canceled on me at the last minute, then tried to cancel on me again a week later until I complained. Then someone shows up LATE and did a visual inspection to assess that my furnace is extremely old, everything is faulty or falling apart, likely can not be fixed because parts may not be available, recommends a entirely NEW furnace replacement. Since it is such a HUGE commitment, I declined. I called someone else, they came, fixed it ALL within 30min and said everything is working great. INCOMPETENT SCAMMERS!!"

Our team helps home owners design their bathroom to combine the best of functionality, aesthetics and comfort. We make your dream our mission. We are craftsmen with over 30 years of remodeling experience and are passionate about transforming ordinary spaces into havens of luxury and convenience.
"They started in mid-October and promised to be finished 12/15. They sort of finished 1/28. They promised me that all three of them would work on my projects simultaneously and that they would get everything done quickly. Instead, there was usually just one guy working on things. The shower pan that was installed in my walk-in shower was done incorrectly so it leaked for about a month before I caught it. They did come back to fix it. The measurement of my kitchen was so off that I had to send back two cabinets and purchase another cabinet to make things right. They screwed up the shower door installation in my main bath so badly that it was unusable. That was in January. They eventually came back in April to fix the messed up tile in that shower and said they'd be back in a couple of weeks to finish things up. They didn't offer to come back until last week. By that time, I had already had all the little things and the new shower door done."

FAQs for tankless water heater installation projects in Seattle, WA
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.
