How did a fridge leak impact the walls, ceiling, door jambs, etc?

Was this the water line that serves the cold water/ice dispenser? Even then, not sure how that would impact the ceiling.

Need images in order to help you.

I absolutely agree with you. The leak from the refrigerator had nothing to do with these issues. These issues came about because the floor has been sanded for a total of three times. a new floor install/sand and stain and then the contractor tried to cut corners and do a screen sanding and stain and then a third full sanding and staining. There’s a ton of jarring with the sanding. There are marks on my baseboard and molding and toe kick they are splatters and spills of stain staying in splatters from when they were staining and re-staining the floor. These issues have nothing to do with the refrigerator leak.

Looks like trims need to be repainted. They could have masked off the trims to cut down on the mess.

Did insurance contractor inform you about the need to repaint the trims after finishing? That might have been included in the claim.

No excuse for the mess on the walls. Contractor is responsible for that.

Baseboards will get damaged, one way or another when you replace floors. I would have taken them off altogether, as carefully as I could have, but, they will most definitely have to be repainted. If they used the big sander, and bumped walls, they will have to be patched with spackle, and sanded and primed and either touched up or repainted. As to the ceilings, I have never seen ceilings cracked from using a sander on the floor. That is either an issue with house construction, or another issue altogether. I dont know your area, but, here insurance companies will hire just about anyone to fix a repair or even reroof a house. I Would always do a bit of research and hire someone on my own.

Nail pops & ceiling cracks wouldn't be related to the floor finishing. (Most likely weather/ season related--low humidity because it's winter & the heater is on.)

Initially insurance said they would replace that one spot but came back and said they would replace it all.

So the old flooring was torn up, hauled out and new flooring was nailed down? Then sanded, stained, finished?

IMO, it is unrealistic to expect the trim to not suffer in the process. Best practice would be to remove the trim (which will also result in some damage & probably need to replace some pieces) for the duration & then re-install, fill nail holes, etc. & repaint.

Either way, your house has undergone some major surgery. You have to expect there to be some scars.

I don't know how old your house is, but I've lived in old (and somewhat old) houses with good solid hardwood floors. If they sustained water damage, I'd go to replacement only as a last resort.

In fact, in a couple of cases I did have permanent stains, and just decided to let them go. Over the decades, hardwood inevitably accumulates scars and stains. In a way, that's part of its character.

Besides, you can't buy wood today that's anywhere close to the quality of what went into those old floors.

IMO, it's usually better to just live with it.

If, you have low ceilings. There is one possible way that your ceilings can be damaged. That would be during coating. If, the contractor is using a telescoping paint pole. They have it extended out too far and whacked the ceiling with the end of the pole. Without photos, I would not be able to confirm.

I have taken out sconces in ranch style homes.
