I wouldn't sign up with these guys even if it were for free. In fact I'd give zero stars if it were possible. They have the absolute worst customer service I've ever experienced. My annual bill came 4 months late and when I called to re-sign my contract, they refused to waive the restart fee. This after having had them service our septic for over 10 years. Sure, they claim they've mailed out 3 bills previously (including the one I just received), but I never received either of the first two. Evidently the loyalty of a long-time customer means nothing to them and truthfully, on the phone their customer service acts like they 100% don't care. When I mentioned that I'll consider taking my business elsewhere, they said "ok". That's it - "ok". Unbelievable. They will not get another dime of mine read more

Drove by this place dozens of times since moving to Joliet, but never had a chance to stop in until we were having septic issues and needed a hook/key to open our tank to see what this issue was. These guys had the piece in stock and at a great price - even offered to show me the proper way to use the tool. They know a heck of a lot more than just tanks here for sure read more

WOW! Customer service was incredible from the office staff all the way to the field guys. I had to have a well & septic inspection performed last minute to facilitate the sale of my house and these guys were out the next day! We diagnosed issues with the aerator and had it back up and running in less than 48 hours. Anyone who knows the nature of this business knows that is impressive to say the least. THANK YOU Norwalk Tank!! read more

We just purchased a home in the area that had one if Norwalk's septic systems. I called into their office and spoke the service manager, Brittany, and she was extremely helpful. She explained the system to me, how it works,the parts and what's included on the servicing. She answered all my questions and then some. She was very polite and patient with all me. I would definitely recommend this company if you need you septic serviced. read more

This is the best precast business I have dealt with in my 20 years of working with manholes. Every person I have talked to has been nothing but nice and has given me amazing deals. read more

I am very pleased with the excellent service and experience when I was a customer of Norwalk Tank Company.

After 15 years, I am embarrassed that I referred clients to this company and used them at my Homer Glen home. While under contract with only me, a septic problem was discussed with a bystander at the property. Months later, I found out and it has cost me $1000's to repair. Upon confronting Norwalk, they chose to argue with me that this bystander was my brother... 3 times! Note: I do not have a brother. It has been months since I asked that the owner contact me with no results or remedy from them. read more

Norwalk staff has always been very helpful in servicing and explaining any questions I have about my septic system.

I just bought a new home with a mechanical septic system. Coming from the city, I knew nothing about septics. Norwalk's staff educated me about my system. They answered my questions and had the part I needed to keep it running. read more

If I could give this company 0 stars, I would. Norwalk inspected a septic system on a home we recently purchased. The letter sent to our attorney's office reads that a dye test and inspection was performed. "Results indicated no discharge of sewerage to the surface of the ground in the vicinity of said property." We renovated this home and began living in it within the last 30 days. The first time we filled the bathtub with 4 gallons of water and drained it, all of the water came up out of the septic tanks and began running back toward our home. The area smells and any time water is drained from the tub, the sewerage comes up. If a correct dye test were performed, this would have been caught and it would have failed the dye test. We called to discuss this with the company and they told us to "just pump it out". Well, when we went to do that, the water was so high that of a 6 foot deep tank, 5.7ft was full of water. It was discovered that we need a new septic field and system altogether. Had a proper test been performed, the septic would have failed and we would not have bought the property or we would have negotiated $10,000 - $15,000 in septic replacement costs into the deal. We are financially devastated because we trusted this company to test correctly. Not only are we financially devastated, but we have a three year old and dogs that have unknowingly been exposed and now cannot use the yard due to the unsafe conditions. Please be aware when using this company! read more

I would be very careful of trusting this company. After I got ripped off I searched the web and sure enough I wasn't the only unhappy pigeon. Do your due diligence before you engage read more

I went there the other day and they couldn't have been nicer. The first reviewer doesn't say why he had a problem but here's what happened to me. I had a metal sewer cover break while I was cutting my grass. I knew Norwalk had something to do with sewers so I took the broken cover there to see if they had a replacement. They did not carry metal covers but they were going to give me the name and number of a competitor in Elmhurst who might have one. I didn't feel like driving to Elmhurst so I asked them if they had a cement cover which they did and loaded into my car. No problems here. read more
