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!"

Family owned and operated, Dano's Septic also provides services for portable toilets and rentals, single units, ADA handicap approved portable units and stand alone wash stations. Our technicians are friendly, professional, certified and are ready to provide you with the best septic service to keep your septic out of site and out of mind.

"ORGINIAL POST: DO NOT USE THIS COMPANY!!! After spending over $2,000 on pumping, inspection and camera work, I had one simple request- WAIT 30 DAYS BEFORE SUBMITTING FINDINGS TO THE COUNTY! We were trying to work the problem. I called TWICE about this and was told both times, no problem, we will wait. They submitted it this morning. Because they did not respect my wishes to wait, I now have to pay over $20,000 through the county when we had a plan in place to avoid that and get it fixed independently. Go with a company that follows instructions, not absolutely ruins your life. Thanks for the 10 year debt I will now have due to your negligence. My realtor and contractor will be referring all other agents and all clients elsewhere, and notifying them all of this unprofessional behavior. EDIT: Here's how I would have expected Serena, the office manager I spoke to today to enter the conversation: yes, you're absolutely right, we did breach agreement, how can we make it right? Here's what happened: per her: "there was a human error that was not our fault. The result would have been the same no matter what" (no it would not have and she has no way of knowing that). "I have you on record asking not to submit it at all" (I told her yes I did say that, then asked what's the extension period, and we're getting off track). "Here's the history of your septic system" again no, we're getting off track. You admitted three times in this conversation you breached our verbal contract. You say the results would have been the same no matter what, but that's absolute garbage- no way she'd know that. If you truly have nothing to hide, and know you messed up (which you admitted to) send me the phone recordings I requested not respond "we will be happy to do that upon getting subpoenaed.""

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.
