Deer Park Elementary School in Owings Mills will be closed for several months while the building is thoroughly cleaned and its ventilation system replaced.
"We've had some moisture problems and high humidity in the building," said Robert Merrey, manager of office and environmental services for the Baltimore County school system. "We're going to identify the problems and fix them."
Some students and teachers have complained of respiratory problems, he said.
The approximately 400 students who attended the school in the 9800 block of Lyons Mills Road will attend Chatsworth Elementary in Reisterstown while Deer Park is closed, said Myra Treiber, a school system spokeswoman.
Chatsworth is one of the county's five schools for children with disabilities, but Ms. Treiber said the move is unrelated to a controversy over the reassignment of special education children in the county.
"The decision to close Deer Park temporarily and move the students to Chatsworth was made months ago, before the controversy began," Ms. Treiber said.
Mr. Merrey said the bidding process on the renovations will take several weeks and that he won't know how long it will take to rectify the problems until the school has been examined.
"We may need to repair or replace the roof, and we're going to use this opportunity to remove a small amount of asbestos," he said.
