Had the attic insulation upgraded to R50 from R6 with soffit and eave openings done (with baffles) as well as a simple cardboard barrier installed around the attic opening and the hatch weatherstripped, as well as the plumbing and chimney stack.
The sight was tidied up - they used plastic sheeting to cover the floors and vacuumed up the few little bits of insulation that had fallen during the blowing in of the new insulation.
Job was done in roughly 4.50 hours.
