Reviews

"From my first conversation with Courtney, to working with Darren, what a fantastic experience. After some serious gut aches over a company saying they could not pump my 86 year olds mom house or do the repairs to sale her home, I read reviews for Lilly's Septic and thought they could help. Darren is a Rock Star in the septic business and came in pumped the tank and made the repairs without even blinking. The guy knows his stuff! Courtney returned calls promptly and really expedited the job. I can't say enough good things about Lilly's Septic. Thanks again Courtney and Darren."

"I highly recommend Lilly's Septic to anyone needing a fantastic company with integrity, years of experience, and excellent customer service. I've been working with this family-owned company for many years, and I have been highly impressed by their expertise and gratitude to their customers. Darren is a ball of energy, super positive, and anytime my septic needed something he always had it readily available on his truck!"

"Big THANKS to Courtney, Darren and his wife for expediting, my need for a replacement company to pump, stress test, and as-built on such short notice. I was left hanging literally, by Aqua Test on Friday, when their guy I had scheduled, bailed on me a half hour after getting here. Left his shovel and poke bar behind. Their secretary called me and told me they would not be able to do the job. Lilly's stepped up to the plate and got it all done in 30 minutes! Now we can close on my sale and get into our new home! Thank you Thank you Thank you!!! You guys ROCK!!"

"I've had very good luck with Lilly's. Even when they don't service an area, like some of my rentals may be too far, they recommend other services that are reputable. Fair priced, reasonable appointment schedules and timely. Highly rx."

"I was very pleased with the service provided by Lilly's. As a buyer of a new house I was forced to pay for the pumping, inspection, and as built on our new house because the seller refused. Lilly's was very understanding and did everything they could to make the process easy for me. The guys showed up on time even though they got lost and got straight to work. They dug fast and located my septic lid easily. They did all the work and didn't mind explaining all the processes to me. This is my first septic system. They gave me tips on how to keep things operating correctly and were very helpful in general. When our lender needed to confirm the amount paid they responded timely so my closing wouldn't be delayed. They credit card charge made the actual charge different than the invoice and if you have ever dealt with an FHA loan you will know that all numbers have to match exactly. They wrote a letter of explanation and sent a revised invoice with no problem. I will definitely be calling Lilly's for all my future septic needs."

"Absolutely "One of the Best" septic services in King County. I have worked with Lilly for several years, referring many friends and family. Some of the hardest workers in the business AND you've got my business for life! Thank you for what you did today for my family in Redmond, amazing!"

"Everyone I've come into contact with at Lilly's has been great! The girl who answers the phone every time I call is very nice and really knowledgeable about septic systems. On several occasions with the alarms going off on our whitewater system she was able to give helpful information about how to open up the tank lids and identify the problem myself - sounds gross but I am glad to have learned so much about what's going on down there beneath the back yard. She could just have easily scheduled an unnecessary and expensive house call. We've used them twice now for pumping the tank and the drivers were also nice and very cheerful! Highly recommended."

"Called them when we realized we had an urgent problem with the tank. Darren came out same day and assessed the problem. Schedule a time to come and and repair next day. He came back as promised and took care of everything. reasonable pricing, great service. Highly recommend."
