To be safe with anything except a fairly new house, you’d need to excavate around the house, parge the outside of the foundation with asphalt, install a dimpled plastic membrane over that, and then on the inside, fastidiously install rigid foam on the floor and walls, spray foam/tape all seams, etc… Then frame, then drywall.Seems ungodly expensive.

Go to Sherwin Williams and get some good paint, take off the hardware and paint them yourselves in an afternoon.If you can get someone to spray the doors and drawers outside it will look the best.

with an 1880s wood building (age of many 2 flat buildings) it’s not if you have rotted wood but where. for me it was a constant battle caulking/replacing windows spraying insulation to keep cold air out and conducting yearly termite inspections. you might still have some of these issues with brick buildings but you have more time (fix it this year as a opposed to right now) @Mark Ainley curious if you have any other anecdotal reasons why brick is better than wood- i know i’ve heard this come up on the podcast numerous times

Either get a spray bottle of bleach or vinegar to clean it on a regular basis. 

They sent a guy with a bottle of bleach and water to spray all my baseboards.

Fabuloso... just the multi-purpose cleaning spray?

Spray can or sticky film glass frosting.

So what you need to do is break out a spray can of clear shellac.

For us it is the way to go over paying to hire an 'apartment grade' paint crew to spray.

exactly.....we had a tenant with Roaches crawling over the bed of her disabled child when our pest guy went in to spray.
