Recently purchase home that was 50+ yrs old. I had Callrich in to advise on insulation options while I was planning a roof replacement. Rich came on 2 occasions to inspect and provide budgetary pricing to help prevent the ~40% home heat loss that occurs through the roof.
Once the roof was lifted there were large insulation gaps and draft areas that needed sealing. Not good but not surprising given age of house. Equipped with a combination of spray foam and cellulose, Callrich increased my R8 day one rating to R40-R50. In addition, they took before and after photos as evidence of the completed work.
Although the job was 2x what I budgeted the team gave me clear details before committing to the work to ensure I knew what I was in for. I was pleased the revised budget was actually very close to the final invoice.
Most importantly, the house seems quieter, cold pockets are gone, and the furnace cycle much less frequently given the room temperatures are sustained. Well done - thanks.
