Wall Blocking; What, Where and Why?

Ever wonder what’s behind a wall before you start knocking it down? You might be thinking hidden treasures, a load of cash, or at least crossing our fingers that there’s no mold, dry rot, or termites. But what about the wall framing itself? Things installed to a wall should have the proper framing behind it. This is where wall blocking comes in.

What is blocking? Blocking are small pieces of material, usually lumber, installed between larger building components, such as floor joists, ceiling rafters and wall studs. And even though blocking is small, it’s a huge component of any construction project, whether it’s a whole home new build, or a bathroom remodel.

Blocking generally serves two main purposes and at the same time, provides many roles. It makes a house more stable and structurally sturdy and secures backing for other materials to fasten onto. Blocking in floor joists adds weight bearing support and prevents joists from twisting. It’s easier to install drywall, wainscotting, and siding. It’s a must for any upper cabinetry to stay in place and if you want the bath bar not to fall off the wall and the staircase railing to stay put, blocking is a no brainer.

So, when your home construction project is in the framing stage it’s crucial that your contractor doesn’t cut corners. Installation of blocking in every room, exterior and interior of the house will need to be done. Stair-rail blocking, closet blocking, specialty blocking such as wide baseboards and crown molding, fire stop blocking, shower pan blocking, just to name a few. Need to know more?
