If you are concerned your brand new hardwood flooring is making squeaking noises, don’t worry. It is perfectly normal for a brand new hardwood floor to make noises. In the industry, it is called the “snap, crackle, pop” effect. No subfloor is perfectly level and when a floor is first installed, the edges of the boards need to get used to one another. As they rub against each other, the edges become smoother and less rigid. You also have the wood flooring reaching its equilibrium moisture content which contributes to this as well. This could take a year or more to go away depending on the level of traff.
Gaps between boards are one of the most common complaints from people with hardwood floors. It is normal for these cracks to appear in the winter months, and fade away in the summer months. Properly made and installed flooring is expected to have seasonal cracks between the boards of the flooring.
