gap between the floor planks

I'd wait a few months to see if the summer humidity/moisture plumps them back up again so they are tight, then revisit if it appears permanent. Shrinkage on mine were especially bad this year too.

Snuffles,

There is not much you can do, there are some wood fillers that have some elasticity in them but its not a great fix

This thread reminds me of the time I visited c0c0's barn up in C0lumbia C0unty.

Waiting till summer to see the expansion is a good idea.

If you use wood filler, make sure you pick a sandable one so you are still able to refinish the floors in the future.

They also sell wood slivers specifically for filling cracks. You buy a batch of assorted sizes and lengths then use a rubber hammer to wedge them in. They do require sanding to level out the surface, so are easiest to use if you are about to refinish your floors.

any easy/new technology in the last year? :(
Its been a cold winter.

Its been a cold winter. Maybe warm up the place, or get a rug?

Gap between the floor planks is how I'd describe some of the posters on Streeteasy.

is it the lack of humidity from the heat that makes them shrink or is it the actual cold?

curious... you guys having this problem, is it solid hardwood? or engineered flooring?

superfun,

Hardwood and engineered both shrink and expand. There is also prefinished which shrinks even more

Snuffles,

It is the humidity
