Thanks for your input. That's the way I've leaned too but more than anything I want peace of mind... And reinforcing that is a lot of money to spend just for that.
What would a start of a problem look like?
They're 14 o.c. spanning 15 feet. Not sure on load but is is a living room above with one wall being exterior and the other being over the load bearing column down to the basement floor.
It's been about 6 years. No signs of trouble at all.
Would I be seeing problems by now?
