I just purchased a home that was built in 1977. The basement is finished, however the floor needs some TLC.
It appears that the floor currently consists of 2 layers of linoleum tile over cement. There are a couple of dips, like the drain pictured below, but for the most part it seems pretty level. There are spots where plumbing fixtures come above the floor, also pictured below. There doesn't seem to be a moisture issue, however it is rather cool down there. Being that I live in a colder climate (Montreal, Quebec, Canada), I'm thinking that my best option would be to build a subfloor, insulate it, and then lay laminate flooring over that.
This room will be used for my home theater setup.
Pictures (pardon the mess, I just moved in a few days ago)
If a subfloor is the way to go, I have some questions:
- Should I simply lay the beams (framing) over the linoleum tiles?
- What size wood should I be using, 2x3, 2x4? 1/2" or 3/4" ply sheets?
- In order to even out the dips, I'm guessing that I'd simply shim those areas?
- What shoud I use to insulate the floor?
- Should I be concerned about anything else?
