Interesting response to our previous review. The company must have us confused with another dissatisfied customer. We did not purchase our house in 1992; we purchased in 2006. We do not have any invoice that states what they mentioned. read more

I am torn leaving this review. I've spent over $5K with Sullivan Septic over more than a decade. Mostly pump-outs, but also some repair work. When it came time to sell my house, I needed to perform the Septic Smart inspection. Sullivan, thinking they were the only outfit in town, failed my system and insisted I pay them $15K+ to replace the pump stations. I called in two other inspectors who both passed the system and both acted unsurprised by Sulivan's extortionary behavior. Too bad a Boulder staple has become so greedy. read more

I've been a customer since 2006. They have always been very friendly, very thorough and and very reasonably priced! Love this company!!

These guys do a great straightforward and fair job. They really know what they are doing and I would recommend them to anyone in need of septic work, replacement or repairs. read more

We have used Sullivan Septic for nearly 30 years. They are a bit pricey, but very professional, experienced and competent. Recently we needed a septic pipe replacement. Sullivan put a camera down the main line, located the break in the pipe, showed us with a digital video, and provided a detailed estimate for the project. It took nearly 2 months to schedule the job, but that's because they are very busy and in demand. The work was completed in 2 days, with excellent backhoe work and attention to detail. They even took the time to protect some outdoor art work located in an adjacent window well. Septic work is expensive, but here you get what you pay for. Ann D., Boulder read more

They were so rude on the phone!!! We were asking how much they charged to pump our septic system and they treated us like the septic matter they pump. Our neighbors are still venting about their septic system installation and how they bid the installation low and then changed the price drastically higher when they were halfway complete. Our neighbors are in their 70's and left to deal with these intimidating people. read more

Sullivan Septic has been nothing but amazing for me since I moved into my house 6 years ago. They have helped me with pumping, updating my tank entrance, and helping me update the entire system for an additional bedroom added to my home. They took time to review information with me about my county requirements. They saved me hours of work and gave me a great experience. I will never use anyone else. Thanks guys! read more

I called Sullivan Septic to have my tank pumped. They reviewed my home's history and I was told that their records showed that in my last pump they charged $225 more because the tank was more than 100 feet from the driveway and they needed to use extra hose. That was past prices they said...this time that extra hose length was gonna cost $450 more. They said it would be $980 to pump my 1000 gallon tank! I went out and measured...it was 75 feet to the driveway being conservative. Basically I felt like I had been overcharged for my last pumping because they thought they could get away with it. I decided not to go with them because of this and the price. This afternoon I got a call asking if I was going to confirm an appointment and I said I wasn't and that I thought it was dishonest that I had been charged for extra hose the last pumping when it was clear my tank was less than the 100 feet length they had told me required extra hose. I was not yelling this just stating I didn't feel that I wanted to spend $980 for extra hose that wasn't needed. The woman hung up. 5 minutes later I got a call from the owner, Cindy who started yelling at me and calling me names and being extremely rude. I told her I felt they had overcharged me and her story (which conflicted with the previous reason of distance) was that I had a difficult tank to pump so they charged more. I didn't think their past charge was fair and I didn't want to pay $980 with their extra charges to get my tank pumped. I had already been overcharged several hundred dollars for extra hose length that wasn't needed the last time. As a consumer I have the right to shop around and to be yelled at by the owner after discovering that I had been overcharged (not just yelled at but called up to be yelled at ) was really unbelievable to me. Totally unprofessional. By the way , I told my neighbor about this and he said Sullivan's had charged him to chain up their truck when there was no snow in the driveway at all and he personally witnessed them drive in and out with no chains. After that experience I called another service and they are coming next week ( a month earlier than Sullivan's could make time) and they will charge $430...saving me $500. Not only was Sullivan's double the price but they had extra charges, and worse of all they went ballistic on me on the phone for even questioning those charges. I would never call or them again or reccomend them to anyone read more

Don't return calls, won't provide even general estimates on work without a paid inspection first. Being busy isn't a good excuse for poor attitude towards customer service. read more

Be careful, They are very overpriced! Was charged $788 for pumping and inspecting my septic system. Most company's charge half that. Beware! read more

Our high water alarm for our septic went off on a Friday night. I called on Saturday as soon as they opened, left a message and was called back within 5 minutes. Cindy Sullivan told me if she could catch her husband before he went to another pump out she'd have him over to us. Within 40 minutes Kevin was here went right to work, backed up to the septic and pumped it out. They charged $350 to pump out the tank, very reasonable. read more
