As an earlier post indicated, we decided to have all the old pine siding removed in order to install spray foam insulation around the entire house. That step of the process went smoothly, but we were concerned that the old siding would not be up to the task of being put back on the house. After lying stacked up in the backyard all summer and beginning to look a bit forlorn, the siding’s time had come. We started the process by priming the one side of the siding that had been exposed to the elements for those many years. Then, the siding was put back up on the house over the spray foam insulation with the primed side facing in. That left the unprimed side - the side that had been facing in for the life of the house - facing out and ready to be primed and painted itself. Our concerns about the siding becoming warped were unfounded; we were able to re-use just about all the siding and needed new siding on just one small exterior wall to make up for the few pieces that had cracked or were too worn to re-use. In the end, all our discussions and research about how best to insulate the house (drill & fill from the outside; remove plaster walls on the inside and spray in insulation; remove siding and replace with new siding or Hardiplank), we’re very happy with the decision to have the siding removed. We got the spray foam insulation we wanted and we were able to keep the great, old siding that you just can’t find anymore. We’re even fortunate to have a few pieces of siding left over that we’re hoping to turn into bookcases and shoe racks.
