Joist Sistering and Reinforcing

Sistering a joist is a process of attaching additional material to the side or sides of the joist. This can mean screwing a new joist of the same size and length to the old joist, or it can be a smaller structural member. Sistering could also involve sandwiching the old joist with new material on both sides. Typically this involves framing lumber, but it could involve engineered lumber, structural steel or formed steel joists that are made of heavy gauge sheet metal. Our team at Atlas will provide you with a detailed written proposal after we complete a free inspection and evaluation of your existing support system.
