Sonic Decay Detection for Trees
Advanced Technology for Safer, Healthier Trees
Many trees that look healthy on the outside can be hiding dangerous internal decay. These hidden weaknesses may not show visible symptoms until the tree suddenly fails — often causing costly damage to property or injury.
What Is Sonic Decay Testing?
Sonic decay testing is a non-invasive diagnostic tool used by Certified Arborists to detect internal hollowing, cracks, and decay within a tree’s trunk.
-
The test uses sound waves sent through the wood.
-
By measuring how quickly the sound travels, we can detect weak or hollow areas inside.
-
Results are mapped to create a visual representation of internal tree health.
This means we can spot hidden problems without drilling into or damaging your tree.
Benefits of Sonic Decay Testing
-
Early detection – Identify hidden decay before failure occurs
-
Non-invasive – No drilling or harm to the tree
-
Accurate results – Provides measurable, visual data
-
Informed decisions – Decide if treatment, cabling, or removal is necessary
-
Peace of mind – Reduce the risk of tree failure during storms
When to Consider Testing
Sonic decay testing is recommended for:​
-
Large, mature trees near homes, driveways, or high-traffic areas
-
Trees with visible wounds, cavities, or fungi
-
Historic or high-value trees you want to preserve
-
Properties preparing for storm season or selling real estate
