Belaire insured me, some ask, some don't care
It costs 15-20k$ to redo an entire house, and most electricians will tell you it isn't a huge deal, as long as you make sure to use the dielectric paste for all copper/alu connections, and that if you see any faults (flickers, bad connections), to cut power an replace the faulty section a.s.a.p.
Personally, i'm keeping mine for 3 more years, at which point im planning major renovations (60-70k), so having to patch/paint walls wont be a bit deal, as many of them are coming down anyways.
