hi there Its a builder you need just be careful as the wall may be your boundary and moving it forward may not be an option! Probably best to rebuild up to the problem tree trunks leaving them in the wall aa such. Depending in growth speed of trees it may give you a few extra years before more drastic action is needed. Again be aware that the trees are your responsibility in the eye of local council etc and you may need to ensure they do encroach onto the pavement if a public use is there.
