I've always heard gas heat can exacerbate moulding and other finish trim problems, but it's definitely the lower humidity that's causing the wood to shrink. But I've never heard of tile popping up due to low humidity.

I agree, already re-laid some of the tile though Hoping to stop the progression in one of the rooms.

With all the moulding, I’ll wait Until spring and then use an elasticized filler before touch up painting

It’s crazy, there are lots of examples on the Internet of Kyle popping and tenting Dude a slab expansion or contraction but there’s nothing that I can find where the tile just decided to release from the thin set

I suspect a lot of those cracks will close and may not be visible.

My hardwood floors get a few buckles in them every winter but you can't see them in the spring and they are not high enough to come loose in the winer.

I know many of them will, but I want to prevent it from happening . That’s why I posted this thread, for ideas. I’m gonna start with telling the wife and kids not to turn on the exhaust fan in the showers when they shower each day. I’m also going to keep my utility sink in the laundry room full of water all the time in the winter along with maybe the bathtub in the guest bath.

I thought it was normal to get a few cracks in moulding when the house settles. I have a couple but nothing has changed with my doors. The door going into the garage will stick at times depending on the weather but that's it.

The best method since you obviously are getting very low humidity (and the trim may have been run in high humidity) is a whole house humidifier attached to your HVAC system. About $250 plus installation and it will automatically prevent the humidity from dropping too low.

I have one partly because I am a hobby woodworker and build a lot of my own furniture and my traditional joinery is more susceptible to wide humidity swings than furniture built with lots of screws and nails.

If you redo your floors, install the schluter system:



Your tile issue won't happen again without major settling issues.

That sounds like a foundation issue.

That is an expensive way to fix a problem that was likely just cheap/poorly mixed thinset. You are talking about an extra $2.50 or so per square for materials and a lot of extra labor.

Tile in the middle of the floor? I bet it is tenting...

I’d look at your foundation settling from the symptoms you’ve listed.

No tenting in any way, not even hair line cracks in any grout

Nope, not even hairline cracks in the slab where the rooms of tile have just decided to let go of the thinset. Tile guy says he’s never seen anything like it.
They laid the tiles too close to the baseboard or cabinets. This happened to me. Tile suddenly split and popped up. Sounded like a firecracker went off. Had the foundation inspected and the plumbing inspected. Finally, when the floor guy came in, he knew what it was immediatly. He took off the shoe molding and, sure enough, the expansion from the cabinets had put pressure on the tile for years and it finally just popped.

Check your slab. It might be cracked. Look outside to see if there are any bricks separating.
