The best way is to sell them or have them removed for reuse. Recycling yards will buy building materials and some undertake the dismantling as part of the service if you are demolishing a house.
Check your local directory under ‘recycling yards' or ‘used building materials' in your area.
Other means of disposal
Sell them online through specialist sites such as building bargains or general sites such as Trading Post or Gumtree. Try auction sites such as eBay or advertise in the classifieds in your local newspaper.
Tip: Check with your local waste disposal site - many take building materials for recycling. Fees may apply.
