Freedomwerks Home Services was tasked with adding insulation and vapor barrier in a crawlspace that was under a conditioned space. The crawlspace did not have these items and was causing issues inside the building above. I put insulation in every joist bay, nook and cranny that I could and applied a 6mm Poly vapor barrier over the ground. I used tyvek tape over the joints in the barrier to ensure the surface had consistent coverage as required by code.
