A Pre-Blast or Pre-Construction Inspection involves one or more inspectors taking narrated video footage of the pre-existing conditions of your home or business prior to construction or other blasting work taking place. The inspection is completed on the full interior and exterior of the building and takes about 30-45 minutes for a typical single-family home. The video is retained by K&M Inspection Consultants during the construction and a copy can be provided to the owner.
