Lumber Quality in Home Construction: Do You Know the Difference?

As a member of various realtor groups online, I often come across questions and concerns shared by agents supporting each other. Recently, one agent raised an important issue: their client was worried about the quality of lumber being used by the builder for their new home. The lumber was showing signs of splitting, and the builder dismissed it as merely cosmetic. What should the agent do in such a situation?

This scenario took me back to a home construction class I attended years ago when I first entered the real estate industry. One of the key topics covered was how to assess the quality of lumber used in construction—a crucial aspect that is often overlooked.

In fact, it's one of the many questions I routinely pose to home builders on behalf of my clients: "What grade of lumber are you using to frame my client's new home?"

This question holds significant importance because the quality of lumber forms the structural backbone of a home. Cutting corners by opting for cheaper materials can compromise the integrity of the entire structure. Therefore, ensuring the lumber used is of adequate quality is paramount in the home construction process.

Fortunately, determining the grade of lumber is relatively straightforward, as it is usually stamped on the wood itself. Here's a useful rule of thumb to remember: the higher the moisture content, the lower the quality of the lumber.

  • MC-15: This grade indicates lumber with a moisture content not exceeding 15%. It's considered the highest quality and is ideal for home construction.
  • S-Dry (Surfaced Dry) or KD (Kiln Dried): Lumber labeled as S-Dry or KD signifies a moisture content of 19% or less. While not as high quality as MC-15, it's still suitable for home construction purposes.
  • S-GRN (Surfaced Green): This is the cheapest and lowest quality option, denoting green, unseasoned lumber with a moisture content of 20% or more. Using S-GRN lumber poses various risks, including splitting, warping, nail popping, shrinkage, as well as susceptibility to stains, molds and fungi.

For those considering new home construction, it's essential to be vigilant and ask the right questions. Having a knowledgeable realtor by your side can make all the difference in ensuring that your biggest investment is built with quality materials and craftsmanship.

Having represented builders most of my career I am amazed I had never heard of these grades before Rosie Crow .  I couldn't even venture a guess as to how many homes I've seen during all aspects of construction and yet I've never seen a bad board in those homes. All the builders I represented were known as "Top Notch" and now I have an even better understanding as to why.
