Client Satisfaction
EXCELLENT Based on 29 reviews Letao J.2025-05-12Verified I had a great experience working with Alex on my fireplace and chimney. He extended my fireplace with brick and remodeled it using cement board—the finished look is exactly what I was hoping for: clean, solid, and stylish. He also cleaned and repaired my chimney with great attention to detail and high-quality workmanship. Alex was prompt, professional, and clearly knows his craft. I really appreciate how efficiently he completed the work without cutting corners. Highly recommend him if you’re looking for reliable and skilled fireplace and chimney services! Janet Y.2025-05-09Verified I couldn’t be more pleased with the chimney repair work done by OS Group LLC! From the moment I reached out, their team was professional, prompt, and incredibly knowledgeable. He provided a clear and fair estimate, explained every step of the process, and completed the work on time with zero surprises. Alex was respectful of my home, left the area spotless, and the results speak for themselves—my chimney looks and functions like new. I truly appreciated their attention to detail and commitment to safety. If you’re looking for reliable, top-notch chimney repair, look no further. Highly recommended! Pavel R.2024-11-01Verified High level professional Emmanuella S.2024-11-01Verified Very nice work and punctual. John B.2024-10-26Verified They gave me an estimate to repair my chimney and install liners and caps. They came out the next day and did the job. The work was excellent and the price was reasonable. Would definitely hire them again. Dotty C.2024-10-24Verified Alex was great and he fixed our flue chain and added a cap on our fireplace stack. Will definitely use him again if needed and I highly recommend him! Megan D.2024-10-23Verified Honest and Professional. Will be using O.S. Group again. Thank you! Ashley m.2024-10-22Verified My parents were in need a of a long overdue chimney cleaning. I reached out and Alex responded promptly. He was able to come out the next day to clean and was reasonably priced compared to other companies. While doing the inspection he found a crack and promptly agreed to repair and clean same day. We will definitely be calling him back and referring this company to others. Amy G.2024-10-17Verified First, I want to say I made some mistakes even the ones Thumbtack warns you about. I did not get a written estimate and I should have as there was a bit of a language barrier and breakdown in the scope of the project. Alex was awesome so I thought we'd be ok. Some of the concerns I had for the price of the job was attention to detail, scope and clean up. There was a anti moss spray that went on the outside of the chimney stack - no covering of windows or the side of the house. There is this awful sticky material all over two of my windows that I can't get off with any product (see photos)! Dirty tools were put on my brand new carpet that I had to ask for more paper to be put down and the outdoor furniture and wood rack never put back in place (kinda heavy and bulky for me). I'm still not sure if I even got the chimney swept. So learn from me and hoping so will O.S. group as I thought Alex was a really nice guy trying to earn a living. Laurie L.2024-10-14Verified Such a great experience having Oleksander come and clean my chimney, fix my damper and give me a solid plan for the other repairs I requested. I am confident about having him out for more work. Can’t recommend highly enough.
