"It was way too expensive for the work that was performed. They originally said that the pipes leading up to the faucet may need to be replaced and the wall opened up. Previously before engaging them. I asked for a possible quote for how much it would cost and they told me that it was up to the technician. When they came out to do the work that they would determine the amount. I asked the technician how much it would and he told me that it was up to the company to decide for how much the work would cost. When I contacted the company they told me again that it would be up to the technician to determine the how much it would cost by checking the amount of work. I could not get an answer from both of them because they would just keep passing each other on who to ask for the quote. After the project was completed, I was given the bill of about $750+ to replace the faucet, to replace the hoses and the two knobs roughly $350+ each. When I called the company about the price, I was transferred to the dispatchers and was told that I need to talk to the technician for it."

Washington Energy Services
Washington Energy Services has been helping homeowners throughout Western Washington save money and live more comfortably since 1957. As one of the largest home improvement companies in the Seattle-Tacoma area, we are able to provide you with top-quality products and services, installed by our professional craftsmen. Our free in-home estimates ensure you get the right product for your home. We'll be with you through all aspects of your project from the purchase decision, expert installation, quality maintenance and service, and even warranty work should you need it. We assist with permits and rebates, too. Give Washington Energy Services a call today to learn more or to schedule your service.
"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

"This was by far the absolute worst experience that I have ever had with any company. The plumber came out for a shower that was not draining. I am on septic and let them know that my septic was just pumped in July. However they wanted to check anyways. After checking under the baffle inspection, I was advised by the plumber that my septic tanks were full and needed to be pumped. I contacted a septic company they came out first thing the next morning and checked my septic tanks, they were not full and ironically enough was able to pull out a huge clog of toilet paper from the baffle. He advised this is something that the plumbers do but since we just had one out the day before and they did told us the wrong information he would happily fix the problem for us. My husband called Riley Cahill (the manger) the next day to try to talk to him about the situation and try to find out why we were charged so much since there was not an itemized receipt. Riley proceeded to get very defense and angry and HUNG UP on my husband. He then called back left a message that saying he will check with his plumbers on Monday and get back to us. Monday morning I called Riley Cahill to have a conversation of what went wrong and how we will remedy the situation. He proceeded to once again get very upset, raise his voice and was insanely disrespectful (telling me to be quiet and stop talking). Then hung up on me as well. After that he called back to tell me I was wrong, and hung up on me again. I told him during the conversation that I was going to warn anyone I could not to use this company through reviews, DO NOT USE THIS COMPANY!!!!"
