Well done, tamaris. If you had let noisy visitors go by without saying anything it could have been seen as the green light for such behaviour to continue. It was a reasonable request.
My neighbours re just through half way on an 8 week building programme to add an en suite, remove the old bathroom and extend their kitchen. The noise has been unbearable at times. For days we had to have the sub-titles on the tv so we could read the lunch time news!
Tree stripper, wood chipper, every type of saw/drill you can imagine, angle grinders, cement mixers etc. They have worked at weekends and on the bank holiday. The neighbours have spent over 3 weeks away and left the foreman the key. I have had to get vehicles/items removed from outside my property to allow car exit! Not a happy bunny. I have kept my powder dry, for now ...
