We painted the interior, added backsplash in kitchen, laminate floor in BR's, changed some light fixtures, and faucets.Contractor solved the surface water that plagued the foundation- added french drains, graded exterior, replaced the rotted gutter system, and new vapor barrier to crawl space.

It was there when we bought the house.We asked if she would like laminate hardwood floors instead, which would be installed with a vapor barrier.

These dryers heat the drum contents and condense the vapor into liquid that then goes down the drain.

Now you've made your whole FLOOR an ice-filled glass relative to the outdoors, and you're depending on essentially using a fan that blows enough to dry it out each night when the RH dips to keep from rotting out your subfloors.Why don't we, instead, understand that the outside needs to stay outside and the inside inside and install a proper thermal and vapor barrier....somewhere? 

Do you waterproof, encapsulate, or simply put down vapor barrier?

😂 Lol no it is alive and in the vapor barrier of the ceiling 

All new windows (some larger, some removed), new floors and paint, removing a few walls that aren't structural, two net baths, making a basement into a room, closing off another room by extending the floor a little and adding a very small piece of wall, adding a swamp cooler, new water heater, vapor barrier, replacing kitchen cabinets, adding tub in one of the bathrooms, moving toilet bowls a little, adding a larger deck, etc etc

Any requested fee not payable on closing day would obviously vaporize the loan in my eyes.

This creates a vapor barrier that prevents humidity and odor from entering the interior of the house.  

Cons: more maintenance, higher utility bills, need preventative maintenance in place (vapor barrier, adequately sized dehumidifier, HVAC/mini-split), higher insurance.
