My customers can rest assured that Chinese drywall was not
used on any of our projects. However, if you suspect that
your home or business has Chinese drywall, I have provided
a link below for the "test kit" however doing a visual
inspection on the back side of the drywall and obvious signs
of severe corrsion and sulphury odor are enough! We are well
equipped to handle the removal, replacement and quality
tests for these properties.

      How to check for Chinese Drywall

If your home was built or remodeled after 2003, there is a chance that
your house contains toxic Chinese drywall. What is toxic Chinese drywall?
It is a building material imported to the United States during the building
boom a few years ago, which contains an unsafe level of sulfur. This toxic
Chinese drywall has not only led to damage of appliances in homes, but
presents serious health problems as well, including headaches, nose
bleeds, couching, trouble breathing and asthma. Here is how to check
your home for Chinese drywall.
Difficulty: Easy

Step 1
Start by removing the switch plate covers around your home. Any place
where you have a light switch or outlet will do. There will be a bare
copper wire inside the box under the plastic cover. If you can see the
bare shiny copper, your house most likely does not contain Chinese
drywall. However, if the copper wire is blackened, this is a sign that your
house contains toxic Chinese drywall.

Step 2

Check your circuit breaker, often found in the basement or garage of your
home. Again, look at the bare copper wires in the box. Shiny copper is a
sign of no toxic Chinese drywall, but blackened copper means you very
well may have toxic Chinese drywall in your home.

Step 3

Try to get a look at the back side of the drywall in your home. This can be
accomplished by going up the attic and looking at the backside of the
ceiling drywall, or in a crawl through or other place in your home that
exposes the backside of drywall. Look for the words "Knauf", "Knauf
Tiajin" or "Made in China" on the back of the drywall. Any of these is an
indication that you may have toxic Chinese drywall in your home.

Step 4

Lastly, consider getting either a home inspection, "
or a less expensive
and more convenient alternative, a Chinese drywall testing kit."
A good
kit is available from This will allow
you to test your own home for the presence of toxic Chinese drywall.
