Hi Binbin and Sweetsuz,
BinBin, I agree with Sweetsuz that you are quite fortunate, cos the defects you listed 'sounds' minimal. However, you may be one who is not as fussy as me.
My parents' case had no concealed wiring - wiring is exposed. Everything that is metal has rusted. Tiles cracked, windows so dirty they can barely be restored to former glory, household shelter door very difficult to open (was yours the round handle kind?), leaking pipes, door dirty, etc, etc...
Actually, we were quite upset at first. But then we tried to get HDB guy to rectify it. He realllllyyyy took his own sweet time and procrastinated, although some of the things (like metal parts, wall tiles and main door) are replaced. In the end my dad was corresponding directly with the contractors to do the repair jobs. That took a really long time too, cos contractors aren't supposed to take orders from us, but rather from HDB. Also, in the toilet, the border tiles have cracked, but he said that it can't be replaced, cos no more stocks - so how? To date, they have yet finished the repair jobs.
Really wonder why we paid so much to suffer this much! Don't you agree (as in your case)? HDB shd give us a compensation in such cases, where we probably need our own contractor to rectify the works.
But, maybe it was because we were too fussy - cos some others who got the flats in the same block during the WIS didn't really get HDB to rectify much. In fact, one owner also had a difficult-to-open household shelter door. It was so bad that only her contractor could open, but she can't. HDB guy said that it was due to long-time-no-open, after a while would be ok. I really wonder though ... hmm ... do they want to fiddle with the handle when the emergency sirens ring? Many of her rusty handles were also not replaced, because she said it is alright as long as it is still useable. Heee... it made me wonder if I was too fussy.
Regardless, we have recently engaged a contractor. We pray and believe that the house would turn out right.
