Chinese (reactive) Drywall is a serious concern for homeowners and homebuyers in Naples, Marco Island, Bonita Springs, Estero, Cape Coral, Fort Myers and all of Southwest Florida.  “Chinese” Drywall has been blamed for corrosion problems in homes throughout Florida and several other states. Copper plumbing lines, copper refrigerant lines and coils in the HVAC system are being seriously impacted by the gases emitted from the Chinese / odorous drywall.  Many homes have to replace their HVAC coils annually because of the corrosion caused by the “Chinese” drywall.

Just because someome advertises they perform "Chinese Drywall" inspections / assessments / testing does not make them qualified to do so; consumer beware is good advice.  "Chinese Drywall" is an environmental / construction issue and should be assessed by specialists.  Remember most home inspectors are generalists.

Homebuyers should have a 'Chinese" drywall inspection, even if the home was not built after January 1st, 2004.  Many older homes have been remolded and some have had major repairs done after storm damage.  We can determine if your home has a corrosion problem without expensive and inconclusive testing.

On the Florida Dept. of Health website under “Frequently Asked Questions” is the following:

How do I know if I have "Chinese drywall"?

Unfortunately, there is no easy answer to this question. The most definitive method to date is finding a "made in China" marking on the back of sheet of drywall. DOH observed some drywall in several homes with no discernable markings. The origin of the unmarked drywall is unknown. DOH observed that homes with marked Chinese drywall also contained drywall marked as made in USA. Remember that we do not know how many sheets of the suspect drywall can cause problems. DOH did observe at least one home with marked Chinese drywall with none of the associated corrosion or odor problems. The bottom line is we think the question should really be "Does my house have corrosion problems?"

Our “Chinese Drywall” inspection is as FL. DOH suggests.  The question we can answer for you, without expensive and inconclusive testing is:

Does your home have a corrosion problem?  The following criteria are currently used by the FL. DOH to determine whether or not existing conditions in your home meet the case definition of the presence of Chinese/odorous drywall in your home:   1) Black or charcoal corrosion on copper wiring   2) Black or charcoal corrosion on copper refrigerant lines and coils in the HVAC system   3) A drywall stamp indicating country of origin and/or the manufacturer    4) Black or charcoal corrosion on copper plumbing lines   5) Expensive repair or replacement of the air conditioner’s evaporator coils due to breakdown  6) Sulfur like odor in one or more rooms in the home that is known to be not sourced in the waterFor homes built after January 1st, 2004, the FL. DOH states that if you answered yes to two or more of these conditions, your home meets the case definition.  If built before January 1st, 2004 and you answered yes to three or more of these conditions, you meet the case definition..

CHINESE DRYWALL

As plaintiff's attorneys begin to salivate over the defective Chinese Drywall issues, FREA is urging all its Members to include the following in their pre-inspection agreements:

This inspector is not qualified to detect the presence of Chinese Drywall. Accordingly the issue of Chinese Drywall (and its potential problems) is beyond the scope of the inspection report.

For Homeowners

Criteria 1:
Sentinel Indicators of Drywall Associated Corrosion (Possible Case = all 3)

  1. The home was constructed or renovated with new drywall since 2001.
  1. Observed corrosion of air conditioner evaporator coil exemplified by black corrosion on copper tubing components.  The corrosion can result in refrigerant leakage making it impossible to cool the home requiring coil replacement.  Coil failures indicative of this problem typically occur every 6-14 months
  1. Observed metal corrosion, indicated by blackening of one or more of the following:
    • copper wires, ground wires, and electrical connectors
    • un-insulated and un-coated copper pipes and fittings
    • chrome-plated bathroom fixtures
    • silver and copper jewelry
    • mirror backing in bathrooms

If you have answered yes to all three of the above indicators, the home meets the criteria for “possible case”. Continue to Criteria 2 or 3 only if home meets the criteria for “possible case”.  Trained professionals performing home assessments based upon this case definition should use their experience, training, and professional judgment to establish their inspection procedures and sampling strategies. Professional judgment is necessary to determine the number of samples and weight of evidence needed to meet each set of criteria.  A trained professional, not the homeowner, should conduct inspections and testing described in Criteria 2 and 3.

For Trained Professionals

Criteria 2:
Supporting Indicators of Drywall Associated Corrosion (Probable Case = 1 or more)

  1. Observed markings on the back of drywall indicating the country of origin is China.
  1. Objective analysis of drywall in home finds Strontium levels exceed 2,000 mg/kg (ppm), indicating the gypsum used in the drywall was probably mined in China.  Analytical methods commonly used for this include XRF and ICP. 2, 3, 5, 7, 8, 9, 10, 11, 12

If you have met the criteria for “possible case” and answered yes to at least one of the above indicators in Criteria 2, the home meets the criteria for “probable case”.  These criteria do not confirm that the drywall causes corrosion. Identifying the origin of the drywall is considered a screening tool for suspect drywall, but confirmation requires analysis described in Criteria 3.

Criteria 3:
Confirmatory Evidence of Drywall Associated Corrosion (Confirmed Case = 1 or more)

  1. Elemental sulfur (Orthorhombic sulfur, cyclooctasulfur, S8) content of gypsum core exceeding 10 mg/kg (ppm), indicating the gypsum in drywall samples from the home contains the source material that is believed to contribute to the reduced sulfur gasses emitted from corrosive drywall. Analytical methods commonly used for this include GC/ECD, GC/MS, or HPLC. 1, 2, 3, 4, 6, 8, 9, 10, 11
  1. Laboratory analysis of suspect drywall headspace for reduced sulfur gas emissions (H2S, COS, CS2) indicating drywall samples from the home emit reduced sulfur gasses capable of causing copper corrosion. Analytical methods commonly used for this include GC/SCD.6 Results that are indicative of corrosive drywall must be established by each laboratory based upon internal procedures, comparison to control samples, and validated methods.
  1. Qualitative analysis of suspect drywall for its ability to cause corrosion/blackening of copper under controlled conditions, indicating drywall samples from the home emit gasses capable of corroding copper.  Results that are indicative of corrosive drywall must be established by each laboratory based upon internal procedures, comparison to control samples, and validated methods.

Lee County Residents can get a tax break for damage from “Chinese” Drywall

 Chinese Drywall can cause damage to your homes HVAC system, copper piping, and wiring and may even affect your electronic systems such as TV’s and computers.  Lee County Property Appraiser says if you can prove the Chinese drywall is harming your home, you are eligible for a tax break this year. http://www.winknews.com/news/local/51633142.html If you too are living with Chinese drywall and have been since at least January first, you could get a big break on this year's taxes.

"I think it could average $100,000," Lee County Property Appraiser Ken Wilkinson says. Because that's how much, Wilkinson says, it could cost to strip a home to the studs and rebuild it. Each homeowner's claim will be judged on a case by case basis for reassessment.

Kampf says that kind of a tax break is a great start but not enough.

"If I tried to sell my house to you or to anybody else, there would literally be no takers and the value that would be offered to me would be the ground only, which is probably on the order of $20,000," Kampf says.”

“THE FLORIDA PROFESSIONAL COALITION FOR CHINESE (REACTIVE) DRYWALL”  has drafted a protocol which should be published for peer review soon.  Attendees to the “Chinese Drywall Removal Protocol Peer Review Seminar” sponsored by the IAQA Ft Lauderdale Chapter and Florida Atlantic University were given copies of the 4th draft of this living document. 
IV. Building a Team to Fix this ProblemBy matter of unfortunate predicament, should a home owner find themselves in a position without a responsible builder to remedy the situation, they need to build a “team” to help solve the problem-not the least which should include:

NEWS:     "Chinese Drywall" cause for leaving home;

http://www.cnn.com/2009/US/05/06/florida.chinese.drywall.family/index.html

“PARKLAND, Florida (CNN) -- Yorelle Haroush fled a million-dollar South Florida home this week, chased out, she said, by drywall made in China that's emitting vapors that smell like rotten eggs.

"I said, 'you can't stay there anymore, because you're sick every minute,'" the family's longtime physician, Dr. Ross Nochimson, told CNN. "They're sick on a weekly basis. Ear aches, sore throat. I give them something, and they're sick again."

“On Thursday, Florida Attorney General Bill McCollum encouraged homeowners to avoid potential scams like the sale of bogus test kits, door-to-door solicitations of home inspections by alleged “experts” with no qualifications, the sale of sprays and applications which allegedly cure the drywall corrosion problems and the sale of ozone generators, which could actually accelerate the corrosion of copper.”

“The presence of defective imported drywall cannot be determined by ‘testing’ the air in the home,” said McCollum in a press release issued April 23, 2009

May 7, 2009

In the past 3 weeks we have attended 2 seminars on Chinese (reactive) Drywall; each had attorneys speak, one experienced in Real Estate issues and one experienced in environmental issues. 

 The lawyer for environmental professionals stressed repeatedly that the inspector should / must have Errors and Omissions insurance that covers Odorous / Chinese drywall assessment.  (Indoor Air Quality Seminar at Atlantic Coast University) 

The lawyer experienced in Real Estate issues stressed to the Home Inspectors that they make sure their agreement excludes Chinese drywall and that they make sure their client signs the agreement. 

Chinese or Odorous Drywall is not part of a Home Inspectors “Standard of Practice”; what they do or don’t do. (Home Inspector group meeting in SW Florida)  We have people claiming to be experts in everything and no one seems to be asking what qualifies them.

A  Professional will have:

 

·         A Certification that meets the American National Standard 1100 approved by the American National Standards Institute ( ANSI)  http://www.naplesmoldinspection.com/id47.html

 

·         Insurance (minimum):

$1,000,000 Liability

Professional Liability: $1,000,000 / $1,000,000 limit /claims made

Microbial Consulting Coverage: $1,000,000 / $1,000,000 limit /claims made

Note:

Professional Liability, E&O that covers Chinese Drywall assessments and Preliminary mold inspections / testing.

Microbial Consulting Coverage, E&O that covers MOLD Post remediation inspection/testing (Clearance)

News:
“It is official, Chinese Drywall has been found in St. Augustine.

We verified that a 2006 St. Augustine home was indeed built with
Chinese Drywall. The home was built by a small builder in town and not one of the larger track home builders mentioned in the Class Action Suit.

According to the homeowner, the construction supply lists indicate that half the home was built using two different wallboards. Both types of wallboard were provided by a very well known construction material supplier.

The homeowners describe typical “
Chinese Drywall” symptoms over the last couple of years. Air handler coils have been replaced twice. Multiple plumbing fixtures have tarnished and/or corroded. The sulfur smell is not bad all the time but some days are worse than others perhaps relating to the humidity level.

Take note:
*this is not just occurring with large builders.
*this is not a South Florida problem
*homes may contain just part
Chinese Drywall.
*A sulfur smell is NOT always detectable.
*This home is not in a newer subdivision.”
ACCORDING TO LOCAL SUPPLIERS, NOT ALL KNAUF CHINESE DRYWALL IS BAD.

Another recent inspection confirmed a home with KNAUF China ASTM C-36 drywall but with absolutely no signs or symptoms of corrosion or odors.

Here are two photos from my inspections of Knauf Drywall. One is from Tianjin (known to be bad) the other from Donssuan (supposedly NOT bad).
