Abstract Background Damp buildings are commonly remediated without removing employees or ongoing medical surveillance. Methods We examined paired pulmonary function and questionnaire data from 2002 and 2005 for 97 employees in a water‐damaged building during ongoing but incomplete remediation. Results We observed no overall improvement in respiratory health, as reflected in symptom scores, overall medication use, spirometry abnormalities, or sick leave. Four employees went from borderline bronchial hyperresponsiveness to bronchial hyperresponsiveness; six developed abnormal spirometry; three more reported post‐occupancy current asthma, and four hypersensitivity pneumonitis. The number of participants without lower respiratory symptoms decreased from 27 in 2002 to 20 in 2005. Respiratory cases relocated in the building had a decrease in medication use and sick leave in 2005. Conclusions During dampness remediation, relocation may be health protective and prevent incident building‐related respiratory cases. Without relocation of entire workforces, medical surveillance is advisable for secondary prevention of existing building‐related disease. Am. J. Ind. Med. 54:269–277, 2011. © 2010 Wiley‐Liss, Inc.
