"Amazing service received by Berardi. Contacted them in the evening and they responded in a few minutes and came over same evening to look at my broken gas heating system. Very knowledgeable and was quick in getting the parts needed and unit up and running again. Very impressed with them coming out evening and the following Sunday where many companies are closed. Highly recommend this company that goes above and beyond."

"Handy Hubby Steve repaired cement stairs and installed a new outside back door. He did an awesome job. Steve was always on time and made sure everything was done properly. His prices were very reasonable. Great personality. Very personable. I will definitely use him in the future for any other repairs I need done."
