AUBURN – Recent heavy rain and wind followed by a few days of hot weather in an old school building created smelly classrooms at Edward Little High School.

Billy Hunter, who heads up maintenance operations for the Auburn School Department, told the School Committee on Wednesday that the mess has been cleaned up “and the situation is under control.”

As of Wednesday, no smell was detected, Principal James Miller said.

Environmental expert Gary Bates was brought in, examined the place and concluded there was no mold, Hunter said. “There’s nothing there,” Hunter said.

Two weeks ago, wind blew rain water into the exterior walls of the east side of first floor.

On the school’s outside walls, the siding has come apart from the walls and at places pops out. That allowed water to get into the walls, getting insulation wet and/or leaving water between the walls.

A few days of 80-degree weather that followed cooked up the soggy insulation and water, creating a bad smell in eight or nine first-floor classrooms, Miller said. Two classrooms on that side of the building “escaped the misery.”

Maintenance crews had to remove built-in bookshelves in classrooms to get to the water and insulation, Hunter said. The old insulation was removed, the interior walls cleaned up, and new insulation was installed.

The work was mostly done after school so classes were able to continue in the rooms, despite the smell. If extra classrooms were available, some classes were temporarily moved, Hunter said.

Some students complained they felt ill because of the smell, “but just a few,” Hunter said.

While Hunter and Miller told school committee members the situation is under control, they said they’re continuing to monitor rooms. The situation could change quickly, they said. It’s the nature of the building, they said.

“The building was built in the ’60s. It’s an old building, and it’s very challenged as far as the siding,” Hunter said.

And the building has poor ventilation.

Workers are trying to reattach the old exterior siding to the walls, he added.
