Question

Wood Floors/Perpendicular to Joists?


I want to have wood floors installed on the first floor. But the first room to the left of the front door has floor joists that run counter to the other 5 rooms as well as counter to the entryway and hall. So if the prefinished planks have to be perpendicular to the joists the "flow" is going to look weird (at least to me--one room will be north/south and everything else on the first floor would be east/west).

I have seen that it is desired that the flooring be perpendicular to the joists but is it required? (I want to sell the place in another year or so and don't want to "fail" an inspection nor do I want to sell someone a lemon.)

Any help would be appreciated.....

Wood floor is nailed into the sub-floor
Not needed to nail into the joists as far as I know

Wood floor or engineere floor?
Floating floor or true wood?

As Dave correctly said, it is cosmetic, not structural. If you have any osb down for sheet goods you removed, you'll want to replace that with real plywood to hold the wood flooring's nails securely. Break the ply on the joists. Don't use rosin paper. This is way better to stop any crawl space moisture from ruining your new floor: http://www.fortifiber.com/aquabar_b.html Box stores carry it. Be safe, G

Thanks for your response but I understood that the boards (3/4" solid wood) were to be installed perdendicular to the joists for stability purposes---that otherwise there would be sagging and/or separation over time.
Having said that, another site suggests that bracing from below....2 by 6 blocking between the joists on 24" centers from below is a "solution".
Any comments.............Thanks again for your help.....

Here is a quote from the FAQ from a local hardwood flooring company.

5. What direction can my floor run?

Installation has to be across the floor joists or on a diagonal. A 1" thick or greater subfloor will give you the option to run hardwood in any direction. Most subfloors are 3/4" thick, so by adding a 1/4" subfloor, your floor can accommodate a different direction.

I am sure the experts will chime in here shortly.

My joists all run East-West under my floors
Main room & dining room (open - same floor) run perpindicular to the joists
Main bedroom & 2nd bedroom run the samer way as the floor joists
The house is almost 60 years old

For the 2 bedrooms the floor runs parallel to the door opening into the room
I think it looks better that way
