Essex Fire and Rescue said it got the call at 5:22 a.m. and the first unit arrived on the scene 15 minutes later.
A spokeswoman said firefighters were on their way to Chappel when a second call sent them 3 miles away. She said officials are trying to determine why the firefighters were rerouted.
Bernard Jenkin, the M.P. for the area, said it was unclear whether the delay caused Ball's death.
"However the fire service should conduct an internal enquiry, urgently, to establish why the delay occurred and if it was decisive I would certainly wish to know the outcome and I imagine the coroner would also be interested," he said.
