We renovated our place, well not really, just the top ceilings and we painted that washroom staircase. The place still looks the same to be honest, just a little cleaner. For the washroom area hall, we attached a brush to a long stick with tape to reach the top crevices, it was amazing, I wish i took photos.
The ceilings apparently haven’t been opened for 20+ years so it was interesting to see the innards. Not sure what else to say, I guess this is our clean start before the school year rolls in.
