I have sold building materials for the past decade and I am very good at showing people how to do things around the house. Basic repairs for plumbing, sheetrock, painting, moulding, etc. I am NOT licensed or certified. I just have learned a lot of stuff over the last decade and will pass some on to you.
I am also good at figuring materials for decks, roofs, sheetrock, sheds, fencing, etc.
