Tree Subsidence Surveys
Identifying the Role of Trees in Structural Ground Movement
When buildings show signs of subsidence, trees are often suspected as a contributing factor. At Black Mountains Tree Consultancy, we carry out specialist tree subsidence surveys to assess whether nearby vegetation is influencing ground stability particularly in areas with shrinkable clay soils.
Our reports combine arboricultural expertise with clear, site-specific analysis, helping homeowners, insurers, engineers and local authorities manage risk, resolve claims, and make informed decisions.
What Our Subsidence Surveys Cover
- Tree species identification – Some species are more likely to influence soil moisture
- Size & root potential – Understanding the tree’s capacity to draw water
- Distance to structures – Measured root spread vs proximity to foundations
- Soil type assessment – Particular focus on shrinkable clays and moisture dynamics
- Tree condition & water demand – Health and physiological uptake
- Recommendations – Root barrier options, pruning, removal, or monitoring
We can also liaise directly with engineers or insurers, providing clear and defensible data to support subsidence claims or decisions.

FAQ – Tree Subsidence Surveys
What causes tree-related subsidence?
When tree roots extract moisture from shrinkable clay soils, it can lead to soil shrinkage and ground movement.
Which trees are most commonly associated with subsidence?
Species like willow, poplar, oak and sycamore are commonly flagged due to their high water demand and root spread.
How close does a tree have to be to affect a property?
This depends on species, size, soil type, and structure depth — our surveys assess all of these.
Will the report tell me if I should remove the tree?
Yes — the report includes tailored recommendations, which may include pruning, removal or alternative management.
Is the survey suitable for insurance claims?
Yes — our reports are accepted by insurers and provide clear, evidence-based findings.
Do I need a soil test?
We may recommend one if soil composition and shrinkage potential are unclear from visual indicators or local data.
Can this apply to cracks in garden walls or paths?
Yes – subsidence can affect more than just buildings. We assess impact across the site.
How long does the survey take?
Most site visits take 2-4 hours, with reports delivered within 5–10 working days.
Will you work with my structural engineer?
Absolutely – we regularly collaborate with engineers and surveyors to give complete site overviews.
Do you offer follow-up visits?
Yes – if ongoing monitoring or phased works are required, we can return to reassess.
