hi I am looking to buy an old house around cheras area, but i am well aware as old houses have wiring issues. Since I am going to make some renovation of hacking walls and extension to the house, would it be wise to install new wiring for the house?? Someone here got experience for a 3k sqft dbl story semi-D like roughly you guys know how much is needed just for re-wiring??

another question for sifu's, should I take additional loan for renovation cost or i should fork it out myself??

new wiring - essential

new water piping - important

for a 3k sq.ft hous, rewiring charges including lighting points, power sockets, around RM 5k - 10k. price vary due to many different factors

new water piping is essential since most older houses use either copper or GI pipes. copper is still ok, but prone to leaks (pin hole cracks) while GI will cause slow water (blocked pipes)

renovation? get professional help. since most old houses (esp pre merdeka) are built using english standards. lots of steel bars in the concrete, and the damn concrete is of very good quality, so it's hard. very hard. steel bar reinforcement corroding might be a big concern, so, perhaps u need extra reinforcement when doig renovation

since u plan to renovate ur whole house which including wall hacking, just go ahead re-wiring for ur house (it is advisable to re-wiring to avoid any unnessacery work to re-do: after renovated and shift in, only found out wiring problem, then hack again?)
