Identify and Repair All Leaks and Cracks
The following are common building-related sources of water intrusion:
windows and doors: Check for leaks around your windows, storefront systems and doors.
roof: Improper drainage systems and roof sloping reduce roof life and become a primary source of moisture intrusion. Leaks are also common around vents for exhaust or plumbing, rooftop air-conditioning units, or other specialized equipment.
foundation and exterior walls: Seal any cracks and holes in exterior walls, joints and foundations. These often develop as a naturally occurring byproduct of differential soil settlement.
plumbing: Check for leaking plumbing fixtures, dripping pipes (including fire sprinkler systems), clogged drains (both interior and exterior), defective water drainage systems and damaged manufacturing equipment.
Protection From Water Damage
interior finish materials: Replace drywall, plaster, carpet and stained or water-damaged ceiling tiles. These are not only good evidence of a moisture intrusion problem, but can lead to deterioration of the work environment, if they remain over time.
exterior walls: Storage areas should be kept clean. Allow air to circulate to prevent potential moisture accumulation.
