My experience with Leonard & Son’s felt like the good old days when service was personal, based on integrity, and able to respond to a customers need. I put a bid on a house and needed a fire-place inspection during a time of year where getting one was next to impossible. You know the drill when buying a house; the rushing and second-guessing things left me a bit unsettled. While talking with Jillian on the phone, I found myself sharing personal concerns regarding my situation. She provided perfect service. She remained professional and yet personable. She gave me what I needed as a consumer to make my decision and stepped in as a friend when I felt vulnerable and need extra emotional support. She spoke frank and provided the information I needed to make a good decision for myself. After the call, she took it upon herself and requested special accommodations from her service group that would meet my needs in the tight schedule, she called me back unexpectedly and offered me options I never expected. Jillian was fantastic, she heard me, listened to me, went out of her way to accommodate me, helped empower me in the midst of what felt like a high-pressure situation, and showed up for me in ways I never expected. She was a gem. Then, Malik came out to check on my “soon-to-be†(fingers-crossed) fireplace. He did all the typical things a person does to attend to the service call however, there was just something about him that was different. He was engaging, but not over the top. A quiet voice with a present attentive spirit. AGAIN, he heard me when I spoke, he responded in a genuine manner, he assessed the situation and said that he could save me money on this service call because my fire-place wasn’t that dirty. (He could evaluate it without having to clean it first.) I just really can’t explain it. There is something different about these folks. All I know is that I felt attended to, cared for, and like these folks were looking out for me. Being in my 50’s, I remember a time when things like service, quality, and integrity really mattered in business. When you actually had an exchange with a person, who heard your need, and did their best accommodate your request. As a consumer today, it is rare to find myself in a human exchange at all anymore let alone get someone to hear my personal need or respond to me with any sense of flexibility. All the “self-serve stations†and “self-check-out portals†aren’t much of a help. Often, when I do find myself dealing with a person rather than a portal, it seems like I feel a need to protect myself from the scripted sales techniques designed to drum up more business. My experience with Leonard & Son’s felt like the good old days when service was personal and based on integrity and “response-ability†to a customers’ needs. Folks like Jillian and Malik are a rare find these days. After the inspection was complete my significant-other and I stop at Leonard and Son's business location to offer them an extra-special “thank you’ for their help. When we drove up to their location, we knocked on the door and they let us in to meet Jillian face to face. The owner came out and greeted us, and the rest of the staff joined in too. We all chatted for a couple minutes and it was one of the warmest welcomes to a community I could have received. In a matter of seconds, it felt like we were among old friends. When I went to shake Jillian’s hand as a thank you she reach out and gave me a hug! All that to say...not only did I get the services I paid for, I got so much more that money can’t buy these days. I felt welcomed, genuinely cared for and supported. I haven’t known these folks very long, however, they already feel like friends. They have something special going on there at Leonard and Son’s and they won my trust in the future.

Work completed on time in a professional manner. I had a call back for a minor problem, and the technician repaired it quickly and completely after being notified.

Honest. Knowledgable. Timely. HIGHLY recommend. We called Leonard & Sons in November, just to get squeezed in by January... we didn't mind; being that booked up must be a good sign. Emily answered all of my questions and was very easy to work with. ✠Caleb and Evan showed up about 20 minutes later than expected but CALLED AHEAD to let us know. ✠We had no idea how much equipment they required but huge blankets/covers were on our floor before any of it was even brought inside. ✠As a team, they were able to inspect the outside of the chimney/roof area, clean and inspect the inside of the chimney and even show us and explain what they could see on their video monitor- all in a little over an hour- leaving NO MESS. ✠This truly is a "3 generation company": their knowledge runs deep, they do not oversell and will give you straight answers about the integrity of the chimney and what options you have moving forward (our fireplace is quite old). ✠The price? Completely reasonable and we will call them from now on. Job well done, guys! âœ

Called Leonard and Sons because of all the good reviews I've read and I'm glad I did! They came out to evaluate a leak coming from my appliance flue they walked me through the possible issues that could exist and the fix for it. They even walked me through how to properly use my gas fireplace. These guys are very professional and knowledgeable!! Thank you guys!

Leonard and Sons fixed my chimney, sealed the external bricks and installed a gas fireplace (with a remote!). They were very punctual and knowledgeable. They were also efficient and neat. I must say I love my new has fire place! I thought I would miss the wood burning fireplace but I don’t! An extra benefit is that my dog (an 8 year old Boxer) thinks I fit it for her comfort!
