What Is Cedar Tongue and Groove?
Tongue and groove is a method of fitting similar objects together, edge to edge, used mainly with wood. In this design, one side of a board has a tongue (a protruding ridge), while the other has a groove (a corresponding slot). These edges fit tightly together to form a flat surface.
When made with cedar, this system creates wood paneling that’s not only easy to install but also visually seamless. Cedar tongue and groove boards are commonly used for:
- Interior walls and ceilings
- Exterior siding
- Cabins and saunas
- Porches and soffits

Types of Cedar Used
There are several types of cedar commonly used in tongue and groove applications. Each has slightly different characteristics in terms of appearance, grain, and resistance to the elements.
Western Red Cedar
This is the most common type used for tongue and groove boards. It has a warm, reddish tone and a straight grain. Western Red Cedar is prized for its resistance to decay and insects, making it perfect for both indoor and outdoor use.
Eastern White Cedar
More common in the eastern regions, this type has a lighter color and tighter grain. It’s slightly less durable than Western Red Cedar but still offers excellent performance for siding and interior paneling.
Inland Cedar
A more budget-friendly option, Inland Cedar is grown in drier climates and may have more knots. It still maintains decent durability and is suitable for less visible or sheltered applications.

Installation Tips
Proper installation is key to the long-term performance and appearance of cedar tongue and groove boards. Whether you’re tackling the project yourself or hiring a contractor, following best practices ensures the wood looks and performs as expected.
Acclimatize the Wood
Before installation, allow the cedar boards to acclimate to the environment where they will be installed. This helps prevent expansion or shrinkage after they are mounted.
Choose the Right Fasteners
Use non-corrosive nails or screws, such as stainless steel or galvanized options, to avoid staining the wood over time. Hidden fasteners or face nailing at the tongue can improve aesthetics.
Leave Expansion Gaps
Wood expands and contracts with humidity. Leave small gaps around the edges of walls or ceilings to accommodate this movement and prevent buckling.
Seal or Finish as Needed
Depending on the application and exposure to the elements, applying a protective finish or stain can extend the lifespan of the boards. For outdoor use, UV-resistant finishes are recommended.
Maintenance and Longevity
Cedar tongue and groove is relatively low maintenance, but regular care can preserve its beauty and structural integrity over the years.
Indoor Maintenance
- Dust or vacuum with a soft brush attachment regularly
- Wipe with a damp cloth to remove buildup or stains
- Reapply finish every few years if desired
Outdoor Maintenance
- Inspect annually for signs of wear, mildew, or damage
- Wash with a mild soap solution and rinse thoroughly
- Re-stain or reseal as needed to prevent fading and weather damage
With proper care, cedar tongue and groove boards can last several decades, retaining their charm and durability throughout their life span.
