When homeowners discover that tree roots may be linked to subsidence damage, the conversation often moves very quickly towards one proposed solution: remove the tree.
But is tree removal always necessary?
Not necessarily.
At Tree Law, we regularly advise on disputes involving trees, buildings and insurers, and one of the most important points we try to bring into these discussions is this: subsidence claims are rarely as simple as “tree equals damage”.
In a recent Sunday Times reader question answered collaboratively by Sarah Dodd of Tree Law and chartered arboriculturist Sharon Durdant-Hollamby, a homeowner asked whether there were alternatives to removing a neighbouring apple tree allegedly linked to subsidence. The answer reflects a growing shift in both legal and technical thinking: in some cases, there may be viable ways to manage the risk and stabilise a property while retaining the tree.
Subsidence Is a Multi-Disciplinary Issue
Tree-related subsidence sits at the intersection of arboriculture, engineering, soil science, insurance and law.
Before any remedial strategy is selected, the underlying evidence must be carefully examined. Questions should include:
• Is the tree actually causing the movement?
• Is the movement seasonal?
• What are the soil conditions?
• What type of foundations exist?
• Is the damage progressive?
• Are there other contributing factors?
This matters because, in practice, we frequently see situations where the evidence does not conclusively establish that a tree is the sole or primary cause of the damage. In those cases, removing the tree may not resolve the issue at all.
The Traditional “Fell the Tree” Approach Is Being Challenged
Historically, insurers and property owners often treated tree removal as the default solution. That approach can create tension between neighbours, result in the loss of valuable mature trees and, in some circumstances, fail to solve the underlying problem.
Increasingly, however, alternative engineering and arboricultural solutions are being explored.
Root Barriers
Specialist underground barriers can sometimes be installed to prevent further root encroachment beneath a property. These systems are highly technical and suitability depends on soil conditions, root patterns and site constraints.
Underpinning
Where movement is linked to moisture-sensitive clay soils, underpinning may allow foundations to extend beyond the zone affected by seasonal moisture fluctuation caused by roots.
While underpinning is often viewed as a major intervention, modern approaches can sometimes provide a targeted solution without requiring tree removal.
Resin Injection and Ground Improvement
Newer technologies involving polymer resin injection or soil stabilisation techniques may help reduce shrink-swell movement within certain ground conditions.
These solutions are not appropriate in every case, but they demonstrate how the industry is evolving beyond the assumption that the only answer is removing vegetation.
The Importance of Tree Management
In some circumstances, appropriate tree management can also form part of the solution.
Carefully planned pruning or cyclical reduction regimes may help reduce water demand and encourage root retrenchment away from structures. However, these strategies must be approached cautiously and professionally.
Poorly executed pruning can destabilise a tree, reduce amenity value or even worsen long-term issues.
This is why collaboration between legal advisers, engineers and experienced arboriculturists is critical.
Trees Matter Too
There is also a broader issue emerging in subsidence claims: environmental balance.
Trees provide enormous ecological, climatic and social value. As awareness around biodiversity, urban canopy cover and climate resilience grows, blanket removal strategies are coming under increasing scrutiny.
That does not mean trees should always remain. Public safety and property protection remain essential considerations.
But it does mean the conversation is becoming more nuanced.
The right question is no longer simply:
“How do we remove the tree?”
It is increasingly:
“How do we resolve the problem proportionately and intelligently?”
A More Balanced Future for Subsidence Claims
At Tree Law, we believe the future of subsidence resolution lies in evidence-led, collaborative and proportionate decision-making.
That means:
• properly investigating causation
• exploring alternatives before recommending removal
• balancing property protection with environmental considerations
• bringing together legal, engineering and arboricultural expertise early in the process
Tree-related subsidence can be complex, emotional and highly technical. But with the right team and the right evidence, solutions may exist that protect both homes and trees.
