Why doesn't anyone ever fix up or clean buildings in the Fallout universe?

It's been hundreds of years since the nuclear war, hasn't it?

Maybe brick and cement are hard to come by, but every building is falling apart and crumbling and nobody seems to be doing anything about it even when it's someone's house, or the NCR's regional headquarters!

Jeannie May Crawford runs a motel and doesn't even bother to clean out the room with some bleach and rags!

Why is there no progress towards any reconstructing, even on a small scale?

When life gets hard, you have to prioritize.  Food and drinkable water are scarce, there's danger everywhere, and it's very difficult to eek a living out of this unforgiving land.  
In that kind of situation, a little dirt on the floor and a couple of holes in the walls don't seem like that big a deal.  Even for folks that are relatively well off, having a spotless brightly lit space just isn't high on the priority list anymore.  That kind of thing is for an age that has come and gone.
