Creaky Hardwood floors

3 Replies

I recently bought my first three units building. The middle unit has a hardwood floor and it makes a squeaky noise when someone walks on the floor. This noise is coming throughout the whole unit floor. However, I wanted to install vinyl plank so I took advice from many contractors but their opinion was not the same. Some advice to install vinyl on top of the hardwood floor with insulation to avoid that noise and other suggested to remove the hardwood floor completely and fix the underneath part before installing vinyl. Any thoughts?

I'm not a flooring expert but I believe the hardwood creaks because it's moving. That can be fixed by nailing it down and securing it. I don't know if vinyl plan on top of hardwood would stop the creaking completely, but it would certainly help. Removing hardwood would require you to then lay down a new subflooring, then put down the vinyl plank. That's a big expense.

@Nathan G. is spot on. The squeak comes from wood rubbing as it moves (kind of like cricket wings). If you are covering it, I would recommend screwing into the floor joists with flooring screws to prevent movement prior to vinyl installation. This Old House has a quick video on the cause and a fix if you want to keep the floor exposed using a specialty screw.

The subfloor wasnt glued to the joists. The finish floor (if hardwood) wasnt glued to the subfloor. 

I dont know your actual condition but what I have done in the past that worked was this. If you have removed it to the subfloor and it still squeaked I have taken a biscuit joiner and put a thoroughly glued biscuit in the  seam where it made a noise. Glued it good and let it dry overnight. Then I shaved it with a chisel. This is not ideal but it does help. 

It just wasnt installed right or it is very old and was installed before glue was the norm. Glue is the answer.
