Hi,

I'm fairly new to hardwood floors, and after a few years of usage, I just noticed that there's some unsightly bubbling on some of the hardwood in my kitchen. It's slightly raised. Should I be concerned, and how can I fix/stop it from happening more? There doesn't seem to be water seepage below the tiles?

Thanks,
Kevin

The easy thing to rule out would be a moisture issue. You need to find a moisture meter the check the areas. Some meters do not need to penetrate the wood to give a value. Compare the value in the bubbled area with values not affected.

are you able to stick a pin in any of the bubbles? if yes, then it could be a finish issue, if you cant get a pin in and there's resistance, its likely the wear layer of the wood that's raised and the board should be replaced as a manufacturer defect (after eliminating excess moisture/humidity as a factor)

It looks like an engineered floor to me - do you happen to know the brand? Do you have any information about the installation, how long ago, what finish was used etc? It looks like a pre-finished product, which is why I'd get the manufacturer involved.
