I'm "renovating". Projects I've done, am doing, or plan to do:
1. rebuilt the garage (was standing on 3 corners and swayed if you leaned on it). Included new car-sized door, new people-sized door, and 2 new windows, all to replace broken or rotting originals.
2. scrape/paint the garage
3. new gutters (old ones were falling off the house and not functional)
4. a ton of re-landscaping - slowly, me and my mom. This includes digging up what will probably end up being at least 2 full pickup truck sized loads of landscape rock and either reusing it or somehow getting rid of it (haven't figured out what to do with it, and most is still in the ground). Moving around existing plants, pulling massive amounts of weeds, and planting new plants.
5. painting walls, ceilings, doors, and woodwork inside.
6. ripped out the old smelly carpet, will put new carpet in when I'm done painting and am willing to spend the money on it.
7. replacing the electrical wiring (original knob and tube)
8. roof/flashing repair
9. need to rebuild the chimney or something. It needs work, not sure the extent.
10. replace/repair 2 storm doors (one replace, one repair). Includes somehow repairing/replacing some of the frame cause it's cracked.
11. paint exterior of doors and windows
12. replacing probably all the light fixtures. a couple b/c they're unsafe, mostly because I hate the originals.
13. replace 2 toilets. they're not working right, and repeated efforts to repair are not sticking.
14. replace all faucets. don't work right and were/are corroded.
15. various other plumbing redo's/repairs - 1919 house, hodgepodge of plumbing, and previous owners did some stupid shit.
16. replace bathroom floor that is currently stick-on-tile on plywood, which is probably on top of an older floor. this floor actually has an unpleasant odor, thanks to previous owner's children. Don't ask.
I could keep going, I have a very long list. Yes, some of this is purely cosmetic, and I'm doing it because I want to. But a lot of this stuff is needed repair/maintenance or updates for safety and function. What I'm not doing is moving walls, etc. Though I would love to rip out the kitchen and redesign it so it works better, the layout is very awkward. I'm living with it indefinitely.
I'm also doing a LOT of this myself, or getting some help from friends/family. Some things I've had to hire out, but while those are the bigger dollar items, they're certainly in the minority of projects.
