Introduction
Trees add beauty and value to properties throughout Sudbury, Suffolk, but their roots can sometimes cause more harm than good. While most homeowners appreciate the charm of a mature tree in the garden, very few consider what’s happening beneath the soil. Tree roots can stretch much farther than expected, and when they do, they may begin to interfere with nearby buildings.
At Sudbury Tree Surgeons, we’ve seen first-hand how seemingly healthy trees can contribute to major foundation issues. If left unchecked, this type of root intrusion can lead to structural damage, cracking, and costly repairs. Understanding the warning signs and knowing when to act is essential for preserving both your home and your trees.
How Roots Damage Foundations
Contrary to popular belief, tree roots don’t force their way through solid concrete. The problem arises when they grow into existing cracks or displace soil around foundations. Some trees can draw up large volumes of moisture from the ground, leading to soil shrinkage—particularly in clay-rich soils, which are common across parts of Suffolk.
This movement of soil is known as subsidence, and over time it can lead to:
- Uneven settling of foundations
- Cracking in walls, ceilings, or brickwork
- Sticking doors and windows
- Sinking or lifting paving and driveways
Trees most often responsible for such issues include willows, poplars, elms, and oaks—species known for their aggressive root systems and high water demand.
Common Signs of Root-Related Issues
Being aware of early warning signs can help prevent long-term damage. You should consider a professional assessment if you notice:
- Diagonal cracks appearing inside or outside the house
- Gaps forming between walls and windows or door frames
- Uneven flooring or sloping floors
- A tree growing unusually close to your property (within 10–20 metres)
- Visible root systems disturbing paving or garden walls
While some movement in older properties is normal, rapid changes or worsening signs should not be ignored.
Prevention and Tree Management
Not every tree near a building is a threat. With proper maintenance, many root-related problems can be avoided altogether. Here’s how we help clients manage risk:
- Root pruning: Carefully removing intrusive roots without compromising tree health
- Crown reduction: Reducing the canopy size to lessen water uptake from soil
- Tree species selection: Advising on lower-risk trees for planting near buildings
- Regular inspections: Monitoring growth and structural proximity over time
In some cases, tree removal may be necessary, particularly when roots have already begun to damage a foundation and the tree’s future poses ongoing risk.
