找回以前的貼子,對我來說也不容易,還是簡單再說一遍好了 Possible causes are:
+ y7 M7 Y6 r" ?4 P5 A1. sub floor did not hold tight to the floor joists. Screws are doing better than nails for this purpose.
; z$ Y2 |% |7 J, _2 E5 E+ C2. supporting beams are a bit too far away from each other.
( }7 }! F: l& M1 R) p, z1 f3. supporting beams are not level due to earth settlement.3 m# S/ X5 l: S; N2 e% E1 g: P' _

For 2, you may need someone with engineering knowledge to find out, but there should be a building code governing the span distance. For 3, you can go down the basement to do a visual check yourself.( P/ J% x* V3 r; B# d! `8 g- B
But anyway, insist the builder to fix the problem right away, don't let them get away with 6 months time. |
