My laundry room is upstairs
Im in a terraced house (however the room that the laundry room is isn't touching either side, its in an extended bit off the back)
Its been up there for 2 years and its always been a bit shaky when its spins.
Howeve ive just replaced my washer and the spin cycle is crazy now. It vibrates so badly that things fall off my bath and sink!
Neighbours havent commented but I want to resolve it before they have to.
Its already sat on a mat I hot from amazon.
Its under a counter, would wedging polysterene between the washer and counter top help? Or make it worse?
