House clearance

The search term you need to look for in French is "Vide Maison". Assuming you're in Brussels, here is a list :

The search term you need to look for in English is 'Clearers of furniture'.
Check out www.goldenpages.be and fill in wherever the house is located.
If you are in Flanders you can also check whether you have a local 'Kringwinkel'. They may not clear the whole house but they will certainly take anything that can be recycled for charity and they are free.

There is also a company called Disaster Control who will clear and clean buildings (I don't have an address for them).

there's also Mon Vide Maison: http://www.monvidemaison.be/

Before my contract ended, i needed to clear my house fast - i found https://junkremovalbrussels.be - they came - removed everything in 3 hours. Recommended.

i had many clothes that i did not wear, old furniture to throw away, i did not know what to do, someone advised https://bulkywastebrussels.be, they cleared all the bulky waste i had in ixelles. I am happy with it.
