Pumped our septic tank. These guys were great! Very professional. They jogged back and forth from the truck to my tank. Will definitely use them again.

Pump alarm help 🙂

We had our septic system alarm go off. We called Lilly’s office in the morning and the office staff is exceptionally helpful and troubleshooted the situation over the phone.
They sent the crew out to us within 3 hours. They were awesome! After investigating the situation and doing a lot of troubleshooting work, Lilly’s found that our 20 year old pump had gone out. Darren was back later that afternoon to get the new pump installed for us… Gave us a great price and did an exceptional job… very professional, thorough and just did a great job for us. we will always recommend Lilly’s to all of our friends and family.

AMAZING!!!

Our septic backed up on Christmas Eve! I called 5 companies the day after Christmas and Lilly’s was the only one to answer! They came out within an hour and were AMAZING!!! I don’t write reviews–they assessed our issue well, reassured us, and pumped the tank. They were very professional, pleasant and wonderful to work with. Highly recommend.

Dear Lilly’s
Thanks again for your great service! You were incredibly helpful with the septic system repair permitting process. The septic system repair and septic tank pumping work you performed on the septic system was thorough & complete. Please feel free to use us as a reference.

I will definitely be calling Lilly’s Septic Service for all my future septic needs.

“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 Septic Service for all my future septic needs.

Competitive pricing. Arrived when they said they would. Dirty job done by a professional.
Thank you Lilly

Homeowner – Maple Valley

These people cared more about handling the situation than my landlord. They’re great. The gentleman that arrived was incredibly professional, armed with his own shovel and everything. I’m going to recommend them to all my drywall customers from now on.

Jessica Tyler

Business Owner

Thank you thank you thank you

I don’t like reviewing businesses personally but I actually care for these folks. I live on a tricky property and they made it work without hesitation. Anita in the office did a quick map check and put me on the schedule right then. Nathan showed up two mornings later and made the experience as painless as he possibly could. I needed a new distribution box and he walked me through what would happen.

Needless to say I could tell you more but, just trust that I don’t like reviews, Nathan dug the thing out, alone, in the pouring rain. He’s truly a stand up person!

I go to the office to drop off a cashiers check and get met by Lisa, who I can only describe as family-like. Anita comes out and is the exact person you meet on the phone.. warm. Truly a warm spirit!

Thank you thank you thank you for your help and hospitality! I’ll remember the moment

Super-Friendly
I needed my septic tank pumped so I gave Lilly’s a call. They were very nice and helpful on the phone, and even offered to send me an email of the county records where my septic tank was. The email never came through but I appreciated the offer. The guys came to my house when they said they would and pumped the tank. They were super-friendly and fast.
