Reset the boards with screws not nails and do it from above or below the floor.
Creaking solid wood floor.
Drive in screws from the hardwood floor right to the subfloor or the joist.
With a solid wood floor creaking is generally the result of vertical movement which only needs to be very slight to produce an audible creak.
When the squeaking is due to a gap between the subfloor and the joist or the hardwood floor and the subfloor or the hardwood floor the subfloor and the joist then you.
The larger the noise the greater the movement and a sign that your sub floor may be uneven either because there was a fault in the installation or because you ve got the wrong underlay.
Creaking popping and snapping sounds can emanate from a hardwood floor that has been nailed to a wood subfloor as well as one that has been glued to concrete.
Traditional hardwood strip flooring is the most susceptible to developing a case of the squeaks but all types of flooring can make annoying noises.
Locate the source of the squeaking.
Cut the blocking from the same size dimensional lumber as the joists.
Another effective way to quiet squeaky floors is to install solid blocking in between the floor joists.
If your engineered or solid hardwood floor is squeaking because some of the boards are lifting you ll usually be able to feel play in the floor when you walk over the loose boards.
