Trees are one of the most valuable assets in your garden, providing shade, beauty, and increasing property value. But even the healthiest-looking tree can have hidden issues that, if left unchecked, may lead to serious damage or safety risks. Knowing when to call a professional tree surgeon is essential for homeowners in Reigate, Dorking, and across Surrey.
In this guide, we’ll cover the key signs that your tree may need professional attention, what a tree surgeon can do, and why timely intervention matters.
Signs Your Tree Needs a Professional Assessment
Even minor issues can become serious hazards if not addressed. Here are some of the most common warning signs:
1. Dead or Dying Branches
Branches that are brown, brittle, or falling off indicate that the tree may be stressed, diseased, or nearing the end of its life. A professional tree surgeon can remove these safely and assess the overall health of your tree.
2. Leaning Trees
A tree that is leaning noticeably, particularly after storms, could be unstable. Leaning trees pose a significant risk to property, vehicles, and people. Tree surgeons in Reigate and Dorking can evaluate root stability and recommend the safest course of action.
3. Damaged or Cracked Trunks
Cracks, splits, or holes in the trunk may suggest internal decay or disease. A professional assessment can determine whether the tree can be preserved or requires removal.
4. Signs of Disease or Infestation
Fungal growth, unusual sap, holes in leaves, or insect infestations can all indicate that a tree is unwell. Early detection by a tree surgeon can prevent the spread of disease to other trees and protect your garden’s ecosystem.

5. Overgrown or Encroaching Branches
Trees that grow too close to buildings, roofs, power lines, or pathways may require pruning, crown reduction, or crown lifting. Properly trained arborists ensure that pruning is done safely and correctly, maintaining the tree’s health.
6. Storm Damage
Severe weather in Surrey, such as Storm Darragh and Storm Eowyn, caused widespread damage to trees in gardens and streets. If your trees were battered by high winds or heavy rain, it’s important to have a professional assess the damage to prevent hazards.
What a Professional Tree Surgeon Can Do
A certified tree surgeon can perform a variety of essential services, including:
- Tree Assessments and Health Checks – Comprehensive evaluation to detect hidden problems early.
- Pruning and Crown Work – Crown reduction or lifting to maintain safety, aesthetics, and tree health.
- Tree Removal – Safe removal of dangerous or dead trees, even in difficult locations.
- Stump Grinding and Removal – Eliminates hazards and frees up space for landscaping.
- Emergency Tree Services – Rapid response after storms or unexpected damage.
By hiring a professional, homeowners in Reigate, Dorking, and surrounding Surrey areas can protect their property while ensuring that their trees remain healthy for years to come.
Why Timely Intervention Matters
Ignoring early warning signs can lead to:
- Increased risk of property damage
- Higher costs for tree surgery later
- Spread of disease to other trees
- Safety hazards to family, pets, and neighbours
Regular inspections and maintenance by an experienced tree surgeon reduce risks, preserve tree health, and keep your garden looking its best.
Local Regulations You Should Know
Many trees in Surrey are subject to Tree Preservation Orders (TPOs) or located in conservation areas. This means you may need council approval before pruning or removal. A professional tree surgeon will:
- Advise on TPO and conservation regulations
- Obtain necessary permissions from Reigate & Banstead Borough Council or Mole Valley District Council
- Ensure all work complies with local and national guidelines

When to Call a Tree Surgeon
Call a professional if you notice any of the following:
- Leaning or unstable trees
- Large dead or broken branches
- Signs of disease or pest infestation
- Trees encroaching on structures or power lines
- Storm damage or fallen limbs
Even if the issue seems minor, a professional assessment ensures safety and prevents costly future problems.
