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!"

On top of that, we were able to take advantage of an offer to get a shop card (20 % of equipment) from Costco, a win win for us. If you are ever thinking of it, give them a call."

Percolation testing services FAQs

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.

The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
