I know I'm going to be working on my wellhouse this weekend. Had to cut a hole in the roof in order for the well guy to access and remove the pump, which sits 180 feet down. New pump, works like a champ (my old one was installed in 1988!), and now I have a tarp covering the 14"x20" hole. I'm going to install a skylight so I can see WTF I'm doing out there. I've got the skylight, so I just have to get up there and install and fix my roof, in the process. I hate getting up on ladders, though!
Insulating the wellhouse is right after that. I had to remove a bit of it for the well pump job, so I'll improve on what I had out there. Very rarely are we ever below zero*F, but i want things to be hunky-dory down to -15*F. My cat sleeps out there when the temp drops, so I need to add chicken wire over the insulation so she doesn't tear it out and make bedding from it...like last time!
