Hello Everyone!! I apologize in advance if I'm posting this in the wrong forum, or if some parts of my post belong elsewhere. I'm VERY NEW to understanding the lingo of home remodeling, so I've tried to point out my areas of concern as easily as possible, without making a fool of myself haha But a little info on the property, it was built in 1979 and seems to have been built in a rush, and had the most basic upkeep. The previous owners had definitely tried to take the easy way out on A LOT of "projects", which now has become my problem. One major pattern that appears all throughout the house, that drives me absolutely insane, is how the walls were constructed/have been treated over the years. There has been (what I assume to be) a very shoddy job in drywall taping and finishing that has left every wall and ceiling looking pitiful. 1? Is there a reasonable do-it-yourself fix for smoothing out drywall taping (red arrows), sloppy drywall seams (black arrows), uneven soffit seams (orange arrows), and chipped drywall that's been painted over (yellow arrows)? 2? Are there any do-it-yourself tricks to filling in and smoothing out very deep cracks that have paint build up (pink arrows), cracks that have been painted over (blue arrow), and cracks that have formed through the paint (purple arrows)? 3? Is there any way to fill-in the gaps between the moulding and drywall, and the corners where the two window moldings meet (green arrows)? Again I apologize if I'm asking too much, as you can see there's just a lot of attention needed. Any and all tips and tricks of the trade are greatly appreciated! Thank you!!
