The floor was a big issue before we even moved in. So we decided to change the 2nd floor and the stairs with new carpet. And if we have enough money left, the rest of the house with hardwood.
We then got a good deal with the hardwood, but after getting two quotes from different contractors, I asked myself why would I pay these guys almost a grand (labor only) when I can do this. I was then dead-lock in doing this project by myself (of course, I had help from Sensei Vinh).
