Level monitoring contractors

Level monitoring provides by far the most cost effective method for the investigation of tree-induced subsidence damage, and should be a routine part of any investigations, particularly where:

  • The trees are deemed to be of value to their owner, sufficient to justify proper investigation.

  • The trees are subject to a TPO (in which case results of level monitoring is an essential requirement) or in a Conservation Area.

  • There are multiple trees or other vegetation (shrubs etc.)

The following contractors offer a service of level monitoring. In my experience all provide a satisfactory standard of service and the necessary level of accuracy, but I can take no responsibility for any problems that might occur. Charges vary depending on the travel time to site and number of monitoring stations. Most will also undertake crack monitoring.

They will usually only present the results (in tabular and graphical form), but will not usually interpret the results or make recommendations for tree or shrub management. Please contact Dr Biddle if you require assistance with this.
