"Enea and Eres arrived promptly to remove our basement 75gallon leaking water tank and install a new one they brought with them after my frantic early morning call. They installed the new tank, working perfectly, then carried out the extremely heavy old tank up narrow wooden stairs and with heroic effort managed to heave it up and out of the building and arranged for it to be picked up that afternoon Well worth the cost of the job, thoroughly knowledgeable, and prompt service Will call them in future for more home plumbing needs that arise Thank you to AE Mechanical & Heating/Eno Plumbing & Heating for saving the day!!"

"I recently had the pleasure of working with Shiroka and his team for some plumbing work at my home, including replacing an old toilet and sink. From start to finish, the experience was fantastic. Shiroka was professional, prompt, and courteous. He arrived early and took the time to fully assess the work before getting started. He made sure to explain the process, including the options for new fixtures, and gave me an honest estimate of the cost. The installation of both the new toilet and sink was done quickly and efficiently, with attention to detail. The workspace was left clean and tidy after the job was complete. I highly recommend Shiroka for anyone in need of plumbing services. I will definitely be calling him again."
