Recently purchased a 1950s cape cod style home with hardwood floors throughout. They squeak terribly everywhere in the home. As I got ready to tackle this problem with glue and screws through the subfloor from the basement I noticed that the floor is actually is made up of these layers:
- Hardwood floor boards
- 3/4" Battens that appear to lay inline with the joists
- Brown Paper (presumably to cut down on dust)
- 3/4" Plank Subfloor
Given that extra 3/4" space between the subfloor and the hardwoord finish floor, no glueing or screwing will help my squeaks, but I was more stunned by the construction. Is this a common method in the 50s or any other time? My understanding is that battens would typically be used to aid in installing hardwood floor over a concrete slab, where you have no joists to work with, rather than over joists and a subfloor.
(Another oddity is that there are few runs of conduit in the 3/4" space between the subfloor and the finish floor. Why the heck would you do this when you have a full basement below???)
