My 3 Lawsons Cypr will be felled at the insistence of my neighbour who

I will vacate the house all day as I don't want to be here.
We used to be friends, but now we will never speak again except with

Kind of hedge wars, I suppose.
My poor trees.
Sorry to hear that Christina.
Is your neighbour aware that removing the trees might cause her house
even more damage from heave?
In theory, any damage caused by the trees water uptake should be
reversed as
the ground rehydrates. I said in theory!

Unfortunately buildings don't listen to the theory!
If the house has simply tilted in one piece, it will move back in one
piece. But if the foundations have broken apart due to the settlement (and
that is what cracks the walls above them), the separated sections usually
heave back at different rates. You will very likely find that the part
nearest the removed tree rises faster than the rest of the house since its
subsoil will be rehydrated first.
Also if ground material has leached into any vertical gaps in the
foundations, they cannot fully close up again.
I don't wish to worry Christina, but it would be a good idea for her to
check her insurance.
No worries about that.
I will now wait for my house to heave ( which it will) and let the two
insurance companies fall out about it between themselves.
My insurance company paid out over 20 grand to underpin my house in 2003 and
it's not likely they will be happy if it heaves. The front of my house will
heave now, guaranteed.
