xecton!! just saw ur thread. good luck on ur renovation!
from condo to landed *applause* hehehe

by the way, do make sure that the workers don't stuff anything down your pipes, and make sure they somehow (i dunno how) cover the holes/pipes. As lots of my acquaintances did their renovation only to find out later "here leaking, there clog" because the pipes are all clogged and backed up. The leakage caused was non-stop. Sekejap here sekejap there, until now some don't even know when they would stop.
