Salvage Before Demolition: What Is Actually Worth Saving

The honest hierarchy

Not everything is worth saving. Ranked by what actually repays the effort:

Genuinely worth it - Hardwood. Framing, flooring, joinery, decking. Australian hardwood from older houses is dense, well seasoned and expensive to buy new. This is usually the single most valuable material in the building. - Roof tiles, if terracotta and in good condition. There is a steady market from people patching and matching older roofs. - Solid bricks, particularly older sandstock or distinctive face brick. Labour-intensive to clean, but genuine value where the brick is characterful. - Period fittings. Leadlight windows, cast-iron baths and fireplaces, original door hardware, decorative timberwork. - Working appliances, hot water systems and split systems, if reasonably current. - Solar panels and inverters, if recent and functional. - Copper and brass, from pipework and fittings. Scrap value is real and it is light to handle.

Marginal - Doors and windows, unless period or unusual. - Kitchen cabinetry — rarely survives removal in usable condition. - Modern tiles. Almost never come off intact.

Not worth it - Plasterboard, insulation, carpet, laminate. - Anything already damaged or water affected.

The one rule that overrides everything

Do not disturb anything that might contain asbestos.

In the Illawarra that is a live constraint, not a footnote. The post-war fibro housing across Warrawong, Cringila, Berkeley, Unanderra, Port Kembla and the older escarpment suburbs means a pre-1990 house should be assumed to contain asbestos until a survey says otherwise.

Do not remove, cut, drill, break or lever fibro sheeting, eaves, roof sheeting, or anything backed by it. That includes tiles that may be fixed to asbestos cement sheet, and vinyl flooring that may have an asbestos backing or adhesive.

If you are not certain whether an item involves asbestos, leave it and ask at the site assessment. Asbestos in Illawarra homes explains what to look out for and why you cannot identify it by eye.

How salvage affects the price

Disposal is charged by weight and it is the largest single line in most demolition quotes. Removing material removes weight.

Two things make that saving real rather than theoretical:

Tell the contractor before the quote is finalised. A price built on a 55-tonne assumption does not automatically fall because you took the flooring out. Say what you are removing so the tonnage assumption reflects it.

Agree a deadline. Salvage that runs over holds up the machines, and a contractor sitting idle costs more than the timber was worth. Set a date and finish by it.

How demolition quotes are built covers the tonnage question in more detail.

Sorting is worth more than salvaging, for most people

Here is the thing most owners miss. You do not have to strip the house to save money on disposal — you mostly need the material to leave the site separated rather than mixed.

Clean concrete goes to one stream at one rate. Metal has scrap value. Clean timber is cheaper to dispose of than mixed waste. Mixed waste is the most expensive stream there is, and one contaminated load reclassifies everything in it.

A contractor who sorts on site will generally beat an owner who half-strips a house and leaves a mixed pile behind. Ask whether the quote assumes sorting — it is a more useful question than asking whether you should pull the floorboards up.

Finding a buyer first

Arrange the destination before you remove anything. Salvaged material sitting on a block with nowhere to go becomes part of the disposal problem you were trying to reduce.

Architectural salvage yards and demolition recyclers operate across the Sydney and Illawarra region, and some will walk a house before demolition and make an offer on the lot. That is often the best outcome for an owner — no labour, no storage, no listings, and the material genuinely gets reused.

For fittings and appliances, online marketplaces work well, but be realistic about the time involved in listing, answering messages and arranging pickups.

A realistic plan

1. At the site assessment, say you want to salvage and ask what is safe to touch.
2. Get the hazardous materials survey done first if the house is pre-1990. This tells you what is off limits.
3. Contact a salvage yard and ask whether they want to inspect.
4. Agree a deadline with the demolition contractor.
5. Remove what has a confirmed destination, and nothing else.
6. Let the contractor handle sorting for the rest.

Where the rest of it actually goes

Even without salvage, a well-run demolition recovers a substantial proportion of the material — it just happens at the recycling facility rather than on your block.

Concrete and masonry are crushed and reused as road base and fill. This is one of the more established recycling streams in construction, and it is why keeping concrete clean and separate matters to the disposal cost.

Metal goes to scrap. Steel framing, roof sheeting, pipework, reinforcement recovered from broken concrete — all of it has value, which is why it is pulled out rather than buried in a mixed load.

Timber is sorted by condition. Clean untreated timber can be chipped or reused; treated and painted timber has a more limited pathway.

Mixed waste is the residual, and it is the most expensive stream. Everything that is not separated ends up here.

The practical implication for you as the owner is simple: ask whether the quote assumes sorting. A contractor sorting on site is recovering value and lowering the disposal bill, and that shows up in the price. One loading everything into a single bin is not.

A word on scavengers

Once a demolition is visibly imminent, vacant and semi-vacant properties attract attention. Copper pipe and wiring in particular disappear from unsecured houses awaiting demolition.

That is not simply someone else's problem. An unsecured site is your liability, and somebody stripping copper out of a fibro house is also disturbing material nobody has assessed yet.

Temporary fencing before the house sits empty is cheap relative to the alternative, and most councils expect site security as a condition anyway. If you are salvaging yourself over a couple of weekends, secure the site between visits rather than leaving it open.

Asking at the right moment

The site assessment is when to raise all of this. Say what you want to keep, ask what is safe to touch, and agree the deadline then — not after the quote is signed and the machines are booked.

The one that is not about money

Occasionally there is something in a house worth keeping for its own sake — the leadlight from the front door, a mantelpiece, the timber from a tree that grew on the block.

Nobody will judge you for putting it aside. It costs an hour and it is the only part of the building that continues.

Call 02 4214 4202 or send the property details through, and mention at the assessment what you are hoping to save.
