Underbelly Inspection... What I found is Frightening

[Second Chance]

Has anyone removed the coroplast and fibreglass insulation, repaired/corrected the wiring and plumbing at the various locations, then spray foamed the everything, protected what cannot be foamed and put the coroplast back on? The fibreglass is waste of time and money and does very little….

That suggestion has been put forward and the general consensus is that spray foaming "everything" would create a maintenance and repair nightmare down the road. It would be a mess.

That kind of project would be a very big job, but worth it if you had the time and money. Agree that the spray foam would be very messy and horrible if you ever need to go and so a subsequent repair.
