I highly recommend O’Sullivan Brick and Stone out of Foxborough! I contacted John after searching for a local mason and seeing his company and their fantastic reviews. He got right back to me and came by to look at the front porch where the land was receding, leaving the porch vulnerable and unstable. John gave me a reasonable quote and explained the process fully. He and his crew were professional, highly skilled, hard working, and friendly. My issue has been fully resolved and I have already recommended John to two friends who have had work quoted. I’m very satisfied with O’Sullivan Brick and Stone!! Thanks John!
Had some cracks in basement walls repaired by John O’Sullivan today. I am very pleased with the results. John is kind, professional and extremely knowledgeable. From start to finish it was a pleasure dealing with him. I would highly recommend O’Sullivan Brick & Stone to family & friends.
I would absolutely recommend O'Sullivan Brick and Stone. I have used John for several projects at two different homes and he has been timely, efficient and clean each and every time. His work is immaculate and he does all of the little things that make the job right. Most recently (April 2023) he repaired and sealed both of my chimneys that were leaking for a variety and reasons and I have not had a leak since. His work speaks for itself and he truly cares about each and every project. A true craftsman.
John was great from start to finish. Came out quickly and gave a quote on the spot. We hired John to redo our patio and are thrilled with the results. We added 6 window wells and he installed a pipe/drain to ensure no issues with water in the basement. We cannot recommend O’Sullivan enough.
