With 25 years of Industry experience we are here for all your Sewer System needs. From installations to repairs we handle it, and being locally owned and operated means that you get the highest quality service and response time every time. Give us a call today for your Sewer System needs!
"They helped fix an emergency sewage backup issue, but the external clean-out point should have been placed at the back-end corner of the house rather than the front. This placement missed access to the back-end area, which could be necessary if a liner installation is needed later. That said, hindsight is 20/20. They did a reasonable job based on their proposal, but at the time, we didn?t have enough knowledge to request a better plan. One issue I encountered was their tendency to revise estimates upward during the project, which I did not appreciate. Additionally, they were uncertain whether the sewage and storm drainage systems in my area were separate or connected. Compared to other providers I worked with later, this suggested a relative lack of experience or knowledge. Another concern was witnessing one of the workers urinating in the hole they had dug during the process. I found this unacceptable and feel it?s worth noting. Finally, I recommend checking out https://lni.wa.gov"

"We had a clogged pipe. Logan came out as part of their 93 or free deal they had for clogs. Logan was professional and did excellent work. He had to remove the toilet to clear the clog, which was discussed ahead of time and a reasonable fee on top of the 93. Clog was cleared and all went great!"

"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!!"

Tankless water heater installations FAQs
Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.
Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.
You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.
A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.
With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
