We have some really established trees in our garden. We looked at having them taken out completely some time ago but seem to remember the advice then was not to touch established roots as this could cause settlement. The roots however are causing a problem with neighbours' drive. The drive people want to take the trees down and the roots out. We've said ok if we can get it on qualifed authority (not the driveway people) that it won't cause a problem with our house. So who do we ask? Surveyor? Architect? Anyone know?
You could contact your insurance company to see whether you are liable for damage to neighbours' drive. The insurance company would then probably send round an engineer/assessor to establish what effect the roots may/may not be having and whether or not you ought to remove the trees.
they have been trimmed madcol but the roots are still huge. They've probably been there since the houses were built in the 30s. Good thinking re the insurance company. Would ideally like someone to make the decision who would put things right if it all goes pear shaped. OUr houses are built on marshy land anyway, so really nervous about settlement,
