This can happen over time in older buildings and homes or in a property that was not properly designed. The team at Cornerstone Structural can properly assess your joint damage and recommend the next steps.

What is a floor joist?

A floor joist is a board that runs under your subfloor. They run between the sill plates in your floor. They are supported in the center of your floor by the main bean. Damaged floor joists can cause dips in the floor or cause visually high or low spots. The low spots are caused by failing joists and the high spots are caused by less heavy loads.

What is the sistering floor joists process?

“Sistering” refers to installing another joist and connecting it to an existing joist. This will strengthen structural integrity and repair any sagging. An experienced team of professionals will need to inspect your space thoroughly to determine whether sistering joists are the proper repair method for your specific floor damage.
