Honest. Fair. Trustworthy.

Honest. Fair. Trustworthy. Thorough. A problem solver. Great work ethics. Does not say the job is complete until the site is as clean as he found it. Courteous and professional. This is our 4 or 5th time to work with Andrew at Cooks. (Don’t panic – All for totally different reasons on different systems!) if the service continues as this, we will continue as customers.

I highly recommend Cooke’s for your septic needs.

We needed our septic tank pumped out since buying our house. I called Cooke’s for someone to come out to give me a quote. Andrew R. was sent out, he was professional and friendly. I had a lot of questions since this was my first time living in a home with a septic tank, he answered them all. We also had a guest house that needed pumping as well, I was given a fair quote and had a Service pumper out quickly. John A. came out to pump both tanks. He was also friendly and professional. John and Andrew got the job done quickly and efficiently. I highly recommend Cooke’s for your septic needs.

Local Sewer Department, New Jersey

Efficient and Prideful in Their Work

Tom, Jim, Alex, Chris just did a fantastic job while covering all the safety standards set for confined space. If permitting, I would also like to request the same crew(s) as they are now familiar with the stations. Furthermore, they are efficient and prideful in their work.

Sewer Authority, Eastern Pennsylvania

Spot on and exceeded my expectations

I was extremely impressed with Nate’s professionalism. I threw them a couple twist and all three techs adjusted easily and were very thorough.

They were spot on and exceeded my expectations. I didn’t expect this quality of work and was impressed. You saved me a lot of time and money
