Q: Hi, I'd like to install 18mm thick solid oak flooring in our downstairs rooms (total approx 55sqM). The sub floor is 18mm thick chip board which sits on joists. This subfloor is dry / well aired, but in some areas slightly uneven (where the joists aren't quite level/boards butt), also in some areas the subfloor is a little springy (joist span/thickness of chip board). I'm a DIYer so would like an easy installation solution - which method / underlay would you recommend?
A: Before you entertained any thoughts of fitting your solid wood flooring, Please take a good look at your joists to make sure there are no underlying problems causing the unevenness. I would then recommend you replace the chipboard with 18mm plywood, this will give a perfect, level subfloor that you can then nail or screw your new flooring to.
