I highly recommend CMM Cesspool Service. They have installed a new septic system at my house which was required by Suffolk county health department. CMM made the process seamless from all around and did an amazing job. Not to mention, when they completed the job, the finish grading was ready for grass. I have also use their site work division to excavate for a basement extension. Again great work and will certainly recommend and use again as much as possible. Consult with CMM with confidence. (Basement excavation photos attached for reference as well).

Things happen for a reason. This is way overdue. Couple weeks ago I was having issues. When I called and explained them Robyn was very informative, kind and professional. I learned what another company had done twice in the past wasn’t the proper thing. I called on a Monday night and they came Tuesday morning at nine and were finished by two. The guys are very professional, efficient and neat. I have a septic tank and an overflow tank and where they dug and worked It looks like it was barely even touched; minus the sprinkler line sticking out which is no big deal. It just looks like I have two minor dead patches. There was one minor issue about where to dump excess dirt but it was rectified immediately. Incredible company, don’t go with anyone else.. They really know their sh1t! Pun intended. I will be using them again in a few years. Thank you!! Picture 1/3 septic tank. 2/4 overflow. The after photos compared to the during are insane. Hope these guys got a good commission! And the price for what was done wasn’t much more than what was done

CMM is an amazing company that I’ve used not only for my home, but on several different occasions for work. I am a real estate investor that flips several homes a year and I’ve need CMM to work on many of those projects. I would highly recommend them!

Wow - what a great experience working with CMM. Robyn was super helpful over the phone, and provided an abundance of information. Jose and Cris were amazing. It was immediately clear that they knew what they were doing. They answered all of my questions, were respectful and courteous and took their time doing the job right. CMM is top notch, I highly recommend them.
