Crowning Studs and Its Importance

What Does “Crowning a Stud” mean and why is it important?

“Crowning” is when you take a piece of lumber and you sight it. “Sighting” lumber is when you pick up the piece of lumber and put your eye on the board and then look from one end to the other to see if it has a curve. A piece of lumber can be bowed, crooked, kinked, cupped, and twisted. At Buck Robertson Contracting we always crown all material installed into the structures we build. Crowning your studs is important because it makes for flatter finished walls. We always crown the studs out, which gives us results like this:


The “plumb line” represents what a flat wall looks like. The drywall board goes onto the wall and follows the curve of the wall (concave).

A crowned out wall (which is concaved, as shown above) allows the drywallers to place their mud in the center of the wall in order to fill in the space between the plumb line and the drywall board. This consolidates the majority of the mudding to one location. When mudding a wall, you want a flat surface and to cover the joint made by the drywall board.

Wavy Walls

If the walls are not crowned, the drywall board on the wall will be wavy (as shown below). This will make it more likely for screw pops. This will also add to excessive work for your drywallers.

The examples above are demonstrated with a 2″ deflection (crown) in the stud, which is over-exaggerated. Most studs have around a 1/2″ or less. This shows you how not crowning your studs could affect your wall, if not taken into account.

Small Details

When building a home, the smallest details can make the biggest difference. A general contractor takes on quality control and helps prevent these headaches later on. Our job is to explain to the crews why some of these little details can make all the difference in the quality of the finish of the product. Everything one trade does affect the next trade coming after them, and so on. Buck Robertson Contracting is onsite to communicate with each trade, which allows for all trades to have a fighting chance to produce the best quality home for you. If you are thinking about building a custom home in Nanaimo or a custom home on Vancouver Island think about getting in contact with us.

So what does “crowning studs” mean? It means quality control – and quality control starts with communication. At Buck Robertson Contracting, we do contracting with communication! If you would like your house built with communication call us today (250) 6684866.
