Re: Oak Floor Bulge
No, this is NOT normal. The bulge is likely either a moisture problem or not enough room was left for natural expansion and contraction of the material.
If I had to hazard a guess, the installer did not acclimate the material to the space before the install, and then installed it tight to the walls. Proper installation would have been to have the material on site and stacked in a manner for the ambient air to get around the packaging for several days to a week (acclimation ). Then, a 1/4" to 3/8" gap is left around the entire perimeter which is covered by baseboard or molding of some sort. The gap is for natural expansion and contraction due to humidity and temperature changes.
If this bulge in only in one spot, then there could be a moisture problem either on top of or underneath the floor that is causing it to swell.
