As Professional Tree surgeons from King’s Lynn we Offer the following:

Crown Lifting

Crown Raising involves removal of lower branches of a tree. The objective is to provide head height clearance for buildings, signs, vehicles, and pedestrians. The resulting live crown ratio  should be more than 60% of ​the leaf canopy. Excessive removal of lower limbs should be avoided so that development of trunk taper is not affected.
The Highways Act 1980 requires trees and vegetation do not obstruct the passage of other users.
The Highways Authority requires a clearance height of 2.5m over footpaths and 5.2m over roads.

Crown Thinning

Involves crown cleaning as well as the selective removal of small branches to reduce crown density. The objective is to allow sunlight and air movement to penetrate to interior branches by developing a lighter, more open branch canopy. Thinning should be performed in a way to maintain even distribution of branches and foliage, care must be taken not to over-thin.   Clearing too much inner foliage will adversely affect the health of a tree. Vigorous production of water sprouts on interior limbs indicates over-thinning.

Crown Reduction

Is the selective removal of branches and stems to reduce the height and/or spread of a tree. This type of pruning is required when there is a need to minimise risk of failure of a tree, or reduce interference with nearby buildings or other structures. Reduction shortens stems and branches back to live lateral branches. Reduction should be avoided for mature, old or stressed trees. No more than 30% of the foliage should be removed.


A pruning system in which the upper branches of a tree are removed, promoting a dense head of foliage and branches. It has been common in Europe since medieval times and is practised today in urban areas world wide, primarily to maintain trees at a predetermined height.

Deadwooding / crown cleaning

Consists of selective removal of dead, dying, diseased and weak branches from a tree’s crown. As a tree grows, defective branches and epicormic growth are found in the tree’s crown from time to time. If these are not removed they may affect the health of the tree. Crown cleaning can be undertaken to correct these small growth problems before they have a chance to become bigger issues . 

Section Felling/ Dismantling

Applies mostly to urban situations where trees that need removing are not able to be felled. This might be owing to being in confined spaces, proximity to buildings, roads, power cables, phone lines etc. The tree is dismantled section by section using a variety of techniques, from simple cut and hold to more advanced rigging and lowering.

All operations are performed by NPTC trained, professional tree surgeons with £5,000,000 million Public Liability insurance & £10,000,000 million Employers Liability. Proof of insurance can be seen on request.

All work is carried out to British Standard BS3998 recommendations.
