Tree Cutting Sydney
If people don't take care of the stump, it could get filled with water and get rot. People have to remove the tree stump in order to prevent such problems.
They will also give you a permit so that you can remove the tree. You will also need to check the local laws and regulations so that you know what you can and can't do.
If you try to do the job yourself, you will have a tough time because you will have to deal with the mess you are left with after the job is done.
