A little bit of thoughtfulness goes a long way towards building good will. We have a fridge plugged in upstairs stocked with water and Gatorade weekly for our guys.
We want them as happy and comfortable as can be because people do better work under those conditions.
I've read the top complaints from contractors about homeowners are the following:
-Not being paid on time.
-Being asked to do extra work without compensation.
I have to say that thus far we are having a very good experience with our main contractor.
We had some issues with our masonry work and I'll do a post on that soon.
