I was talking to a guy the other day who works for a flooring company. He told me about a guy who had a new floor installed over a nice looking wood plank floor. He said he would have left the wood planks because they were in great shape. So the customer comes into the showroom and chooses an expensive vinyl flooring that looks like wood planks. They installed the floor, had to put down underlayment first. The total cost of the floor was almost $3000.
When they finished the job they all looked at the floor and said "looks just like when we got here, only a tad darker in color and a little shinier". He shook his head and said "What's the point?". He said he would have given the wood floor a coat of varnish for $25 and left well enough alone.
