Ceiling is Uneven
Acceptable Performance/Condition Where an isolated sag, bulge or area of waviness appears and is not a structural problem, the variation from the specified plane shall not exceed ±1/2 Inch. Surface imperfections due to slight variations in levelness of joints or trusses supporting ceiling board are beyond the builder’s control. Warranty One-Year Work and Materials Undulations caused by normal shrinkage of materials due to drying after construction are excluded from the warranty. Action Sags or waves in ceilings greater than the Acceptable performance shall be repaired. Remarks Even when installed according to the Building Code, it is not unusual to see undulation in drywalled ceilings due to joint finishing. This occurrence can be exaggerated by particular or critical lighting conditions and glossy finishes. Spray-applied textures and matte finishes minimize this condition. Some undulations may also be caused by truss uplift and applying ceiling drywall over major structural components such as beams. See section 9.5 Ceiling/Wall Joint Separation Commonly Referred to as Truss Uplift. |
