Hamilton firefighters spent the morning knocking down an intense fire in Waterdown Thursday.
Crews were called to Beaufort Computer Sales at 295 Highway 5 at Hamilton Street North around 7:30 a.m.
The owner was on vacation, and no one was inside at the time, said Fire official Dave Christopher.
The fire caused significant damage to the building, but Christopher said he did not yet know the cause.
He said fire crews are exhausted from tearing down ceilings and walls chasing hotspots, so additional crews have been called in to relieve them.
“The guys are really taking a beating,” Christopher said.
Christine Maude lives just up the street from the fire, and the smell of smoke and sounds of sirens woke her up around 7:20 a.m.
“I'm surprised by how many trucks showed up,” she said. “There was so much smoke.”
