Floor flex
I had my home built about 5 years ago. Its a 2100 square foot ranch on a crawl space. Specifically in my kitchen, i notice that there is a little bit of floor flex/shaking when walking through the room. Specifically, i have a large island in the kitchen and you can see vibrations in water glasses and such when someone walks through the room. From the LVL mid-house beam to the exterior wall is roughly 16 feet. Can i use a large post, i.e. 6x6 and some screw-type jacks in the crawl space to stabilize this area? The current design is up to code, but i just dont like the flex and want to eliminate it with minimal expense. FWIW, i have no intention of selling this house in my lifetime, so inspections are irrelevant to me, i just want something to soothe my nerves on this issue. If i ever had to sell the house, i could just remove the jacks/post before the sale.
Open to other DIY solutions as well.
