2x4 Rot Board Upgrade
Protect your fence with a pressure-treated sacrificial board for near-zero ground clearance
What is a Rot Board?
A rot board is a pressure-treated 2x4 installed at the bottom of your fence, creating a sacrificial barrier between the ground and your cedar fence boards. This allows us to bring your fence much closer to the ground without risking damage to the cedar portion of your fence.
We coined the name "rot board" because this pressure-treated lumber is specifically designed to take the abuse from soil contact — something cedar should never be exposed to, as it dramatically accelerates rot.
Why Choose a Rot Board?
Near-Zero Ground Clearance
Get your fence much closer to the ground for a tighter fit without worrying about cedar rot. Perfect for properties with dogs or where privacy at ground level is important.
Protects Cedar from Soil
Cedar should never be in contact with soil — it accelerates rot significantly. The pressure-treated rot board takes all the soil contact, protecting your investment.
Extended Fence Longevity
By keeping cedar away from moisture and soil, your fence will last significantly longer. The rot board is designed to be replaced if needed, preserving the main fence structure.
Dog-Friendly Solution
Have dogs that like to dig? The rot board adds utility by bringing the fence closer to the ground, making it harder for pets to dig underneath while protecting the fence from damage.
Important to Know
While the rot board significantly reduces ground gaps, it doesn't guarantee zero gaps everywhere along your fence line. Ground terrain naturally varies, and some areas may require soil adjustment to achieve the tightest possible fit.
Our team will work with your property's unique contours to minimize gaps as much as possible, but perfect ground-to-fence contact along the entire fence line may not always be achievable due to natural terrain variations.
How We Install Rot Boards
Pressure-Treated Lumber Selection
We use high-quality pressure-treated 2x4 lumber specifically rated for ground contact, ensuring maximum durability against moisture and soil.
Strategic Placement
The rot board is installed at the base of your fence, positioned to maximize ground coverage while keeping all cedar components safely elevated from soil contact.
Secure Fastening
We securely fasten the rot board to your fence structure using corrosion-resistant fasteners, ensuring it stays in place for years to come.
Terrain Assessment
Our team evaluates your ground conditions and may recommend minor soil adjustments to optimize ground clearance across your property.
