"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"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."
