Services
McMahon & Sons of Buffalo, NY specializes in all kinds of masonry repair. A masonry wall should last you decades if done properly. If you have cracks in your mortar, brick or stone it may be time to have your wall fixed. Depending on how bad the damage is you may be able to cut out and replace a few stone or brick.
McMahon & Sons Mason Contractors offers new home masonry and chimney repair in Clarence, NY. The majority of our work is done on new home construction in Clarence. We have been featured in home shows and are experienced with large masonry projects. Call us today to talk more about your new home plans or if you need help repairing your chimney.
Chimneys are exposed to harsh weather year-round and the changing temperatures makes the masonry expand and contract which will eventually lead to cracking. It is important to fix this right away so you do not end up with costly water damage in your home. If the joints are cracked or pieces are falling out but the bricks are fine, you may be able to get away with tuckpointing.
The cost of masonry repair depends on what needs to be fixed. In some cases only the mortar needs to be replaced. You can chisel out the brick or stone and reuse them with new mortar. If the bricks are damaged they will need to be replaced. Many people don't realize that the materials for masonry are quite expensive and can be the majority of the cost of repair.

When my roof tear off revealed a structurally unsound chimney, these guys bent over backwards to get the project done for me in a timely fashion. Great people. Great workmanship. Give them your business.

Had them come out to repair my chimney. Some of the mortar was falling out and bricks were cracked. They had to do a 7 course tear down and rebuild with a new flue, a new crown and chimney cap. Luckily they said I didn't need a full tear down since most of the damage was at the top of the chimney, They said it was caused by a poorly made previous chimney crown that didn't go past the brick, so there was no drip ledge. The water can seep into the brick below and crack when it freezes. They also did some tuck pointing for me in a few spots to fill in the cracks.

Very happy with McMahon & Sons. I received a few quotes from other masonry repair companies around Amherst and they seemed the most reasonable as well as reputable. They do work on a lot of newer homes as well as repairs. I had them come to my house in Williamsville to do a tear down and rebuild of my brick chimney as well as build a brand new stone mailbox. Would definitely hire them again and recommend to anyone who needs work done in the north towns.

Very happy with my chimney repair. I had noticed cracks in my furnace chimney and it looked like some bricks were about to fall out. Also the stone cap or whatever its called had a huge crack in it. I called McMahon & Sons since they were very local to me being from the Town of Tonawanda also. They came and gave me an estimate over the weekend and did the repair the following weekend. Chimney is now looking great and I don’t have to worry about it leaking into the house. I would definitely call them again if I need any masonry repair work done.
