I live alone in cottage in a village; the problem is I am concerned to have workmen come to my home; In the past they have trudged into my home to give estimates, I felt very insecure particularly when it was myself and a toddler in the house alone. They often did work that was below standard, but I was not strong enough to stand up to them and hence over the years, many areas of maintenance have fallen behind, as I do not feel safe calling persons whom I do not know. (My son has now left for Uni); And I need to have the holes in the roof plugged up... any suggestions on what I can do would be much appreciated.....
