creaking sound on the wood floor

[helerjo]

Hey,
I recently moved to a rented place with my family in Muskoka. The house seems alright and was within our budget but the flooring here was slightly damaged and the planks have a creaking noise. I know the flooring costs a lot. But I don't have that kind of money. It's hard living here with the floor damaged. I contacted some old friends in Muskoka about the plank flooring and they told to replace only the damaged ones. Even though only a few planks are damaged, many of the planks have the creaking sound. Do you guys know any solution to this? Any suggestion is welcomed.
