1 December 24, 2008 SEDA Construction Attn: Ted Walker 2120 Corporate Square Boulevard Jacksonville, Florida RE: Georgetown Community 2C - Revised Assessment Date: October 27, 2008 Revision Date: December 17, 2008 SkyeTec Project No: Dear Mr. Walker: SkyeTec has completed a limited water intrusion assessment at the living room windows and kitchen sliding glass door at the above-referenced property. The purpose of this assessment was to determine the source of the moisture that has been observed within those areas. SkyeTec visited the property on October 27, 2008 and December 17, Our assessment included visual observations, water testing, thermal imaging evaluation, and a moisture survey. This report summarizes the findings of our assessment and provides our conclusions. Observations and Measurements For reporting purposes the front entrance of the residence is assumed to face due east. Interior walls and the ceilings were finished with gypsum board. A visual assessment of the living room and kitchen and adjacent areas was conducted to determine the extent of microbial growth and unusual moisture conditions. Moisture measurements were obtained using a Protimeter MMS BLD5800 moisture meter. Moisture measurements are obtained by inserting the pins of the moisture meter into the material being evaluated, or by placing the flat surface of the meter onto the material being evaluated. For wood, the moisture content is expressed as percent moisture content (%MC); for other materials the measurement is expressed as percent moisture equivalent (%WME). Generally,

2 %MC or %WME measurements of less than 17 are considered to be dry ; measurements between 18 and 20 are considered to be at risk for moisture damage; and measurements of 21 percent or greater are considered to be wet. The non-invasive mode of the meter provides a qualitative measurement in general accordance with the above scale. We made the following observations during our site visit: Kitchen 1. We observed moisture staining and damage on the upper portion of the sliding glass door return. 2. A water test, utilizing a garden hose, was conducted on the northern portion of the third floor window. The water test resulted in moisture intrusion in the kitchen, water was observed seeping from the upper portion of the sliding glass door return adjacent to the security component. Living Room 1. We observed moisture staining and damage on the upper portion of the center window return in the living room. (1 square foot) 2. A water test was unable to be performed at the time of the assessment. Conclusions Based on the available information, we conclude the following: 1. The moisture impacted building materials in the kitchen adjacent to the sliding glass door is consistent with moisture intrusion through the northern portion of the third floor window penetration during periods of rain fall. 2. Seda construction conducted removal of the stucco along the rear of the residence at the second floor sliding glass door assembly extending to the third floor and visual moisture staining and damage was observed on the OSB adjacent to the lower window corners. It appears that moisture has intruded at these areas during rain events. 3. Seda construction conducted removal of the stucco along the front of the residence at the second floor sliding glass door assembly extending to the third floor and visual moisture staining and damage was observed on the OSB below the roof overhang. It appears that moisture has intruded at the roof flashing during rain events.

6 ATTACHMENT B Limitations This assessment was conducted following standard practices and guidelines. Regardless of the thoroughness of an assessment, it is possible that some areas containing visible mold growth, water damage, and/or elevated moisture content or other indicators of poor indoor air quality were inaccessible or not evident during the assessment. The findings and recommendations included represent conditions evident at the time of the assessment. Building conditions related to indoor air quality, microbial growth and moisture intrusion may be subject to change on a daily basis. Therefore, the conditions observed and reported herein may not be evident in the future. If additional information becomes available which may affect SkyeTec s findings and recommendations, we request the opportunity to evaluate the information and modify our findings and recommendations as appropriate. SkyeTec has endeavored to meet what it believes is the applicable standard of care ordinarily exercised by others in conducting this assessment.
