How Much Does House Demolition Cost?
"What will it cost to demolish the house?" is the first question on any knockdown-rebuild or site clearance, and the honest answer is that it depends — but on a clear set of factors, not guesswork. Demolition is priced on the building, the site and what has to be dealt with along the way. This page explains what actually drives house demolition cost across Tweed Heads and the Northern Rivers, and why an accurate quote needs a look at the site.

The honest short answer
A full house demolition is a five-figure job — most standard homes fall into a broad band that moves a lot with size, construction, asbestos and access, and the only way to a real number is a site-specific quote. Here's what moves the price so you can look at your own place and understand where it will sit.
What drives the price
- Size and storeys. Floor area is the starting point, and a double-storey home costs more than a single-storey of the same footprint.
- Construction. Brick and masonry generate more heavy rubble to break out and cart than a timber or fibro home.
- Asbestos. The single biggest swing factor on older Northern Rivers homes. If present, it must be removed by a licensed asbestos removalist and disposed of legally before demolition — specialised work with its own cost, and not optional.
- Access. An open block with easy machine and truck access is cheaper than a tight coastal or hillside site where plant, bins and trucks have to be worked in carefully.
- Disposal. Demolition produces a lot of material, and tipping fees are a real part of the cost. Sorting and recycling helps, but disposal is unavoidable and significant.
- Slab, footings and extras. Breaking out the slab and footings, removing a pool, big trees or extensive paving, and how clean and level you need the block left all add to the scope.
- Flood works. On flood-affected land, fill and raised-pad works for the rebuild are often quoted alongside the demolition.
Why a site quote beats a phone number
A figure over the phone from a floor area alone can't see the construction, the access, or — most importantly — whether there's asbestos, which is the factor most likely to move the price. A site visit lets us assess the building and the block, factor in the asbestos and disposal properly, and give you an accurate, itemised quote that won't change once work starts.
Getting a real figure
Tell us the address, roughly the size and age of the house, whether it's single or double-storey, and what you want done with the block, and we'll come back with a clear, itemised quote — demolition, asbestos handling, disposal and site clearance broken out so you can see exactly what you're paying for.
Common questions
How much does it cost to demolish a house?
A full house demolition is a five-figure job that moves a lot with size, construction, asbestos and access — so the only way to a real number is a site-specific quote. Size, storeys, brick vs timber, asbestos, access and disposal are the main drivers.
Why does asbestos change the price so much?
Because if it's present it must be removed by a SafeWork NSW–licensed removalist and disposed of legally before demolition — specialised, regulated work with its own cost, and not optional. On older homes it's the single biggest swing factor in a quote.
Can you quote over the phone?
We can give a rough range, but an accurate quote needs a site visit — it's the only way to assess the construction, access and whether there's asbestos, which are what actually set the price. The site assessment is how you get a figure that won't change once work starts.
What's included in the quote?
A proper quote itemises the demolition, any asbestos handling, disposal/tipping and the site clearance (slab, footings, levelling), plus any flood or fill works, so you can see exactly what you're paying for rather than a single lump figure.
