Do any of you try to quantify the amount of slope on a floor? I haven’t found a good way to do it yet.
New home warranties in my area limit the amount of floor slope as follows:
Article Number: 2.7 Condition: FINISHED FLOOR ABOVE GRADE IS OUT OF LEVEL Acceptable Performance/Condition: Within a room, floors shall appear level when viewed from a normal viewing position. Where a floor framed with dimensional lumber appears sloped, a maximum tolerance ratio of 25 mm in 3600 mm applies, when measured between the opposite walls or defined limits of the room or area. Warranty: One-Year – Work and Materials • Minor slope variance caused by normal shrinkage of materials due to drying after construction is excluded from the statutory warranty. Action: Floors in rooms sloped greater than the acceptable performance shall be repaired. Remarks: This item refers to the entire floor surface in rooms. Where a floor is framed with an engineered floor system, minor slope variations caused by the required camber in the long-spanned joists supporting the floor are excluded from the statutory warranty. For uneven areas in floors see section 12.2 “Floor is Uneven”.
I have to come up with a good way to measure it so that my clients can make a claim if necessary.
