My sewer line need to be replaced. The repair team was on time and extremely professional. Upon completing the job, Eduardo took the time to explain exactly what had been done. This company was compassionate and empathetic to my situation, and definitely went above and beyond the call of duty. I would highly recommend them.

I’m extremely happy with work these guys had done. They didn’t mess up my front yard or any of my property, they did small patch to get into my water main line which was leaking for months & replaced. As I waited for other companies(big names in Nassau) for days to give me estimate John was professional & not pushy. Thumbs Up to you guys

This company is the real deal. Professionals from the young lady who answered the phone to our visit from their wonderful plumber Bill. I called on a Sunday morning and they arrived within an hours time. Bill arrived set himself up found the problem and proceeded to explain what needed to be done and made us feel confident that we had found the right company and person to fix the problem. He totally cleaned up after completing the work and the bill was extremely fair for the work that was done. Recommend them highly!

I called on new years day because my sump pump flooded my laundry room and was so glad they came right away, and then fixed it the next day when they could get the parts. They were professional. Courteous and really knew what to do. They used good quality materials and explained everything and cleaned the whole area when done. I would use them again for sure and highly recommend.

Had a blockage in the pipe from the house to the street sewer line. First technician, Mike, showed up and checked out the problem, explained the various possible outcomes, and arranged for a team to come out the next day. Carlos and his team showed up on time and water-jetted out the blockage, explaining every step of the process and providing camera views in real time. We came away satisfied and informed.

The name “Commack” comes from the Secatogue Native American tribe who lived on the South Shore of Long Island between Copiague and Bayport. The Secatogue named their northern lands in the center of the island Winnecomac which means “pleasant lands.” The name may have been inspired because of the area’s flat lands with rich soil, and thick oak forests abounding with plants and wildlife. From its earliest days, Commack, originally spelled “Comac” had fertile soil which made it the perfect land for farming.

Commack is a suburban area, and, like most unincorporated places on Long Island, does not have a walkable downtown or “Main Street”.
