their wrap is not enough. U either buy wrappers to wrap yourself or pay people to help u do. There are such services specially to help and wrap households before HIP.
Even after you wrap or pay other ppl to wrap for you, will still have a bit of dust but it will be worth the trouble. Else you gonna clean like siao after the HIP.
Their wrap is enough.
But after that, the layer of dust, need to use vacuum cleaner clean about 2 to 3 times to remove.
Actually can minimal wrapping, then after HIP invite a cleaning company to come clean the house (or you ownself buy vacuum cleaner standby also can). Price should be similar.
My house use the sweep + mop type (xiaomi) brand. It’s actually a good investment. And no worries, the HIP dust won’t damage the vacuum cleaner, the vacuum cleaner still can use very long after that.
Am typing while outside, but the following vacuum is similar or identical to the one I am using at my house, not advertising, just sharing:
“Xiaomi Truclean W20 Wet Dry Vacuum| 3-in-1 vacuum, Mop with water-flow, Easy to clean, Reduce hair” (about $300)
To think about it: cheapest would be to let the HIP contractors wrap, and then use $300 vacuum cleaner to clean the house after that.
The external companies’ wrapping service, HDB got put caution notice at the ground floor lift lobby (of HDB blocks undergoing HIP) to say that they are illegal. I believe your flat also have.
