DAD ALWAYS SAID, " get estimates for everything you are going to buy or use."
Man has that saved me over the years. Slowing down the shopping process just a slight bit and making sure everything to get handled is covered by written estimates is nice.
Recently we had some small water damage in our basement and had to have insurance estimates before the work to be performed could begin.
Wow eye opening. Good news is we know where we are going to be when we finish the project - cost wise.
ALWAYS get written estimates for everything. It only takes a little longer and takes away any questions later.
