Joist replacement

Question

Hi. I live in 1st floor 1930s maisonette. My loving room and corridor leading to it seem to have springy floor. Whenever i walk everything is shaking. Other rooms and kitchen seem to be much more solid. Living room is roughly 4m x5m. How can this be fixed? Do i need joist replacement?

Muhammad · Accepted Answer

it is repairable by taking off loose nails and insert new ones ,bit longer than older.
Second solution is replace the floor board with the new one.

Hi Karol I would say maybe your chipboard might not have been screwed down to the joist which means if the joists are uneven it will cause this. Do you know if you have had the floorboards changed recently thanks Aaron

This could be the fact that the nails that hold the boards down have loosened so this causes the boards to spring. This is one possible cause.

Hi. You need to take off all the laminate or carpet after remove the plywood to see what the condition of the timbers. If required change them and change the plywood as well.

There could be several reasons, however you will not know for sure until you do not remove the floorboards to check the joists first, which is the worst case scenario,  and if not, most likely your floorboards will need to be nailed down propperly

Aml said chipboard .... 1930s doubt it's chipboard at all and good old fashioned floor boards. 

Could well possibly not be nogged out to make a stronger reinforced joist set up. 
And a good screw up with some 6.0 X 80mm
