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.
Having a home inspection from Goff Home Inspections can
help you identify all of these areas.
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.
