Retrofits make up the core program and provide work for the majority of the youth in T4T. Train for Trades has a contract with Newfoundland Labrador Housing Corporation (NLHC) to complete 60 retrofits annually. This work involves stripping basement walls, removing the framework and on exterior walls, reframing, filling cracks, installing insulation, vapour barrier, dry wall etc. Overall energy costs for the tenants decrease and the space becomes more useable.
