Dawn Homes has planning permission to build up to 118 homes at the former Barrwood Quarry in Stirling Road, Kilsyth.
Some local residents had been warned that a controlled explosion would take place at 2pm Thursday but they were not expecting to be bombarded with missiles.
A statement from Dawn Homes said: "We can confirm that an incident involving a controlled blast at the Stirling Road Kilsyth site took place shortly after 2pm today.
"There were no reported injuries. Unfortunately debris from the controlled explosion exceeded the perimeter of the safety exclusion zone set by the specialist blasting contractors on site.
"It has been confirmed that there were no injuries to local residents or passersby.
"There has been some damage to local properties and Dawn Homes regrets any inconvenience to those neighbours and local people affected and has asked anyone who has suffered damage to their property to report this to the principal contractor on site, Dow Haulage Ltd.”
