Yes, in many cases you can hire a skip bin and carry out your own house strip-out — but there are important rules around hazardous materials, building consents, and restricted work that you must understand before you swing a hammer. Getting this wrong can be costly, dangerous, and even illegal, so read on before you start.
What Is a House Strip-Out?
A house strip-out (also called a demolition strip-out or gut-out) involves removing interior linings, fixtures, fittings, cabinetry, flooring, insulation, and sometimes structural elements from a building. It's common before a major renovation, a full demolition, or when remediating a leaky home. The scope can range from pulling out a kitchen to stripping an entire house back to its framing.
Do You Need a Building Consent?
This is the first question to answer. Under the NZ Building Code, some strip-out work is exempt from building consent under Schedule 1 of the Building Act 2004, but not all of it. For example, removing non-structural linings and fittings is generally exempt, but any work that affects the structural integrity of the building, or involves restricted building work (RBW), will require consent and a Licensed Building Practitioner.
Always check with your local council before starting. What's exempt in one situation may not be in another. You can find general guidance at MBIE Building Performance.
The Big One: Hazardous Materials
This is where DIY strip-outs can become genuinely dangerous. New Zealand homes built before the mid-1980s are very likely to contain asbestos — in textured ceilings ("popcorn" or stipple), vinyl floor tiles, wall claddings, pipe lagging, and more. Homes built up to around 2000 may still contain some asbestos products.
You must identify hazardous materials before any demolition work begins. This is not optional.
Asbestos Rules
- Any friable asbestos (crumbly, easily airborne) must be removed by a licensed asbestos removalist. This is a legal requirement under the Health and Safety at Work (Asbestos) Regulations 2016.
- Non-friable asbestos (bonded, like flat fibro sheeting) in quantities up to 10 m² may be removed by a competent homeowner on their own home, but you must follow strict WorkSafe guidelines for PPE, containment, and disposal.
- When in doubt, hire a professional. Asbestos-related disease is fatal and irreversible.
- Check WorkSafe NZ for current asbestos removal rules and guidance.
Other Hazardous Materials
- Lead paint is common in homes built before 1980. Sanding or grinding lead-painted surfaces creates toxic dust. Use appropriate PPE and follow safe work practices.
- Treated timber (particularly older CCA-treated wood) contains arsenic and chromium. Don't burn it — dispose of it at an approved facility.
Restricted Work: Electrical, Plumbing, and Gas
During a strip-out you will almost certainly encounter electrical wiring, plumbing pipes, and possibly gas lines. Here's what the law says:
- Electrical work is restricted. Disconnecting or altering any fixed wiring must be done by a registered electrician. Check EWRB for what's restricted. You can remove light fittings and power points yourself after the circuit has been isolated by a qualified electrician, but confirm this with your electrician first.
- Plumbing and drainlaying is restricted work under the Plumbers, Gasfitters and Drainlayers Act. Capping or disconnecting water supply pipes and drains must be done by a licensed tradesperson registered with the PGDB.
- Gas work is always restricted. Never touch gas lines yourself — always use a licensed gasfitter.
Safety note: Before any strip-out begins, arrange for your power, water, and gas to be properly isolated by licensed tradespeople. Do not assume a switch or valve makes something safe.
Hiring a Skip Bin: What You Need to Know
Hiring a skip bin is straightforward, but not all waste can go in a general skip. Most skip bin companies in NZ will refuse or charge extra for:
- Asbestos-containing materials (requires specialist disposal at an approved facility)
- Treated timber (CCA)
- Plasterboard/GIB in large quantities (some landfills have restrictions)
- Tyres, batteries, and liquids
Always tell your skip bin provider exactly what materials you're disposing of. Illegal dumping carries heavy fines. Check with your local council about approved disposal facilities for hazardous materials.
| Material | General Skip? | Notes |
|---|---|---|
| Timber (untreated) | Yes | |
| Plasterboard/GIB | Sometimes | Check with provider |
| Asbestos | No | Licensed disposal required |
| CCA treated timber | No | Approved facility only |
| Concrete/masonry | Heavy skip only | Extra charges may apply |
| Insulation (non-hazardous) | Yes |
What a Homeowner Can Typically Do
- Remove non-structural interior linings (after hazmat check)
- Pull out kitchen and bathroom cabinetry (once plumbing/electrical is isolated)
- Remove carpet, vinyl, and timber flooring
- Strip out insulation (check for hazardous materials first)
- Dispose of general building waste via skip bin
When to Call a Professional
Call a qualified tradesperson or demolition contractor if:
- Your home was built before 1990 and hasn't been tested for asbestos
- Any structural walls, beams, or foundations are involved
- You need electrical, plumbing, or gas disconnected
- The scope of work requires a building consent
- You're unsure about anything — a professional assessment is always worth it
A qualified demolition contractor will manage hazmat identification, consents, restricted work coordination, and waste disposal as a package. You can find experienced local demolition contractors on tradedirectory.co.nz.
