Chinese Drywall
In Portland Oregon?

Chinese DrywallDid Portland drywall contractors use Chinese drywall? According to the local supply houses I have interviewed there answer has been no. Does that mean that there was none of it used in the Portland drywall market and how can you tell if you have any?

It is possible that some Chinese drywall made it into the local market. There were two types of drywall imported. Corrosive and non-corrosive. That is the best way to describe the issue, as the discussion has become very technical. What is corrosive drywall?

The corrosive Chinese drywall has high amounts of reactive sulfur gases. These gases react with the materials your home was built with. The corrosive drywall was imported in to the US starting in 2001 (recent sources say the period is between 2001 - 2008). If you remodeled or purchased a house built in 2001 or thereafter, it does not mean you have a issue. What should you look for?

If you have air conditioning, you can check for blackened (normal corrosion has a blue, green, or dark red color. Sulfur corrosion leaves a black color) or corroded copper. It is very common for the copper coils to fail after 6 months to 2 years if you have corrosive drywall. These coils should last 10 to 20 years under normal use! Wow, if it will do that to copper, what is it doing to your body....

If you do not have AC, you can check your electrical fixtures. Warning! If you are like me and get shocked every time you change a light bulb, you better get a professional electrical contractor to examine any wiring. Have them look for black corrosion on any wiring.

There have even been reports of corrosion on silver or copper jewelry. Check your rings! It may be a tell tale sign of corrosive Chinese Drywall.

Follow Your Nose!

The sniff test. Does your home smell like rotten eggs? Or burnt matches? Or fireworks? Those smells can be a sign of corrosive drywall. Fortunately you can detect these sulfur compounds at levels that are not known to cause health issues. But, these irritants can cause discomfort in your nose, throat, and eyes.

Made In China

If you suspect you have Chinese drywall, the next step is to visually inspect the drywall. If you have access to your attic space, you can check the back side of the drywall. Look for "Made In China" or a marker for manufacturers located in China.
