"I called and happened to get Steve right away and since he was in the area he came right over. He examined the blind to determine if it could be fixed without a replacement piece and since it could he did the repairt quickly and efficiently. He was reasonable and very pleasant."

"From the time I met Dennis for my estimate he was very helpful in answering all my questions regarding a tankless water heater and gave me a written estimate on the spot. I upgraded my original tankless water heater and both Dennis and is office staff kept me informed of the price difference in units. Dennis and his experienced grew of technicians did a wonderful job of removing my old hot water heater and installing my new one and any problems that came up they were able to handle. After job was completed they cleaned and vacuumed the area and demonstrated how my tankless water heater worked. I would recommend South Shore Plumbing & Heating to anyone who wants a excellent company that does the job right the first time."

"Anthony was wonderful. Very nice to deal with and talk too loved him. Highly recommend him! And his team of guys were great also. He came back to do our gas fireplace for us also. His pricing is great! And great job done. It was supposed to be two days to do the central air he asked to stay later and was done in one full day. Like I said Anthony's the BEST!!!
