Beacon Plumbing is a plumbing company originally established to serve the city of Kent, Washington "known for its slogan - stop freakin'...call beacon" & its ads with "Marshawn Lynch". Beacon Plumbing was founded by Bill Cahill in 1999 with 1 employee and his son, and was named Beacon Plumbing Heating & Mechanical, Inc. for much of its history. Based in Kent, Washington Beacon Plumbing has now has over 50 employees and has served over 100,000 households, making it one of the largest plumbing companies in Washington. Bill Cahill is the current President and Owner.

"*** BEWARE, GROSSLY OVERCHARGES••• I have a condo in Seattle that my daughter lives in. We had a need to have a toilet reinstalled along with a washer & Dryer that needed to be hooked back up. I live in California and she was unable to do this work herself. I told her to call a plumber and I’d take care of the charges. My daughter had my permission to use my card to pay for the service. She was in a nearby town doing an opening of a new restaurant and was unable to be there and called Beacon to do the work. The tech sent over a docusign which she filled out and provided payment. Afterwards, my daughter sent me a copy of their invoice. It mention the need for some newer parts (hammer arrestors, braided hoses, wax ring and bolts for the toilet. Cost of parts when I priced them out through Lowe’s was roughly $120. They charged my card (my daughter approved it because she didn’t know any better). $2772 for the work. That equates to roughly $2300 in labor for something that should have been fixed in an hour. A very expensive lesson learned for my daughter and myself. This company should be ashamed of themselves. Obviously, had I seen the quote, I would have refused the job. Their response- Jeff, It is actually a contract. Beacon does not offer unearned discounts when the proper prices are charged. Even when reviews are left that is clearly trying to damage the company, are untrue. We are declining to offer an unearned discount at this time. Mark J Sr Mgr Beacon Plumbing, Heating, Electrical & Mech. Inc My response- Well, I never disputed whether it was a contract. My daughter did sign the contract. When I first contacted you I acknowledged such, and my review clearly stated that she signed for it. What your company calls ‘proper prices’ are outrageous. If you have children or grandchildren, I hope they’re never taken advantage of the way my daughter was. I have the money and means to cover the cost, again that was never the issue. Your company is lying if you think I wasn’t truthful in my review. It happened 100% the way I listed. Was the review meant to get your attention, and if it were to damage your reputation, that’s solely based on your company’s ethics, because nothing was untrue."

Sewer Cleaning questions, answered by experts

It's advisable to have your sewer line inspected every three to five years to ensure its proper functioning and detect any potential issues early on. However, the frequency of inspections can vary based on factors such as the age of your sewer system, the type of pipes used, and your property's location. If you notice any warning signs like slow drains, foul odors, or sewage backups, it's essential to schedule an inspection promptly, regardless of the regular maintenance schedule. 

The type of clog in your sewer main determines the required cleaning method. Different types or methods of sewer main cleaning require various tools like chemicals, mechanical removal, or a combination of both. Some of the most common types of sewer main line cleaning include:

  • Minor debris removal: $100–$600

  • Tree root removal: $100–$1,000

  • Trenchless pipe repair: $60–$250 per linear foot

  • General line repairs: $1,000–$4,000

  • Full pipe replacement: $3,000–$25,000

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

Regular maintenance, such as not disposing of grease or coffee grounds down the sink and routine use of strainers, can prevent clogs.
