Protect Your Property from Water Damage
Water may be essential to life, but as a destructive force,
water can diminish the value of your home or building. Homes, as
well as Commercial buildings, can suffer water damage that
results in increased maintenance costs, a decrease in the value
of the property, lowered productivity and potential liability
associated with a decline in indoor air quality. The best way to
protect against this potential loss is to ensure that the
building components, which enclose the structure, known as the
building envelope, are water resistant. Also, you will want to
ensure that manufacturing processes, if present, do not allow
excess water to accumulate. Finally, make sure that the plumbing
and ventilation systems, which can be quite complicated in
buildings, operate efficiently and are well maintained. This
provides some basic steps for identifying and eliminating
potentially damaging excess moisture
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.
-
Ventilation, Heating and Air Conditioning (HVAC)
Systems: Numerous types, some very sophisticated, are a
crucial component to maintaining a healthy, comfortable work
environment. They are comprised of a number of components
(including chilled water piping and condensation drains)
that can directly contribute to excessive moisture in the
work environment. In addition, in humid climates, one of the
functions of the system is to reduce the ambient air
moisture (relative humidity) level throughout the building.
An improperly operating HVAC system will not perform this
function.
Prevent Water Intrusion Through Good Inspection and
Maintenance Programs
You can help prevent water intrusion and excessive moisture
levels by regularly inspecting the following elements of your
building to ensure they remain in good condition:
-
Flashings and Sealants: Flashing, which is typically a thin
metal strip found around doors, windows and roofs, are
designed to prevent water intrusion in spaces where two
building materials come together. Sealants and caulking are
specifically applied to prevent moisture intrusion at
building joints. Both must be maintained and in good
condition.
-
Vents: All vents should have appropriate hoods, exhaust to
the exterior and be in good working order. Review the use of
manufacturing equipment that may include water for process
or cooling. Ensure wastewater drains adequately away with no
spillage. Check for condensation around hot or cold
materials or heat transfer equipment. Heating, ventilation
and air conditioning systems are much more complicated in
commercial buildings. Check for leakage in supply and return
water lines, pumps, air handlers and other components. Drain
lines should be clean and clear of obstructions. Ductwork
should be insulated to prevent condensation on exterior
surfaces.
-
Humidity: Except in specialized facilities, the relative
humidity in your building should be between 30% and 50%.
Condensation on windows, wet stains on walls and ceilings,
and musty smells are signs relative humidity may be high. If
you are concerned about the humidity level in your building,
consult with a mechanical engineer, contractor or air
conditioning repair company to determine if your HVAC system
is properly sized and in good working order. A mechanical
engineer should be consulted when renovations to interior
spaces take place.
-
Moist Areas: Regularly clean off, then dry all surfaces
where moisture frequently collects.
-
Expansion Joints: Expansion joints are materials between
bricks, pipes and other building materials that absorb
movement. If expansion joints are not in good condition,
water intrusion can occur.
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: Exterior walls are generally comprised of a
number of materials combined into a “wall assembly.” When
properly designed and constructed the assembly is the first
line of defense between water and the interior of your
building. It is essential that they be maintained properly
(including regular refinishing and/or resealing with the
correct materials).
-
Storage Areas: Storage areas should be kept cleaned and
allow air to circulate to prevent potential moisture
accumulation.
Act Quickly if Water Intrusion Occurs
Label shut-off valves so that water supply can be easily closed
in the event of a plumbing leak. If water intrusion does occur,
you can minimize the damage by addressing the problem quickly
and thoroughly. Immediately remove standing water and all moist
materials, and consult with a building professional. Should your
building become damaged by a catastrophic event such as fire,
flood or storm, take appropriate action to prevent further water
damage once it is safe to do so. This may include boarding up
damaged windows, covering a damaged roof with plastic sheeting
or removing wet materials and supplies. Fast action on your part
will help minimize the time and expense for repairs, resulting
in a faster recovery.
