Happy New Year I'm in the process of remodelling my house and in checking the structure have noticed that the floor joists are 2 x 7 (true)..they have a span of 13' 2 " with 16" OC... I believe cedar. These joists have been there for close to 100 years and show no sign of bending stress. They are as straight as a die and there is no bounce from above. Although the span seems a bit much can I assume that i'm good to go?
