Simon & Michael came in last Monday morning and added more cellulose fibres in the attic as recommended by our energy auditor. It only took about 3 hours to complete. I asked Michael if the attic needed additional baffles to soffit ventilators and also if it needed additional roof vents suggested by our energy auditor. He said it has adequate number of baffles and roof vents. I only ended up paying the added insulation. They clean up the area where they working on. Thank you guys.
