Replacing spouting in NZ typically costs $40 to $80 per metre for PVC and $70 to $120 per metre for Coloursteel or aluminium, according to Flood Roofing (2026). For a whole house that is about $2,000 to $7,000, and more for a two-storey home. Gutter cleaning is a separate and much smaller job, usually a few hundred dollars.

These are business websites and a deal listing, not independent surveys. Use them to sense-check a quote, not to set a price.
We could not find a sourced NZ price for downpipes on their own. Flood Roofing lists downpipe upgrades and fascia repairs as add-ons without a price, and Impact Roofing Solutions gives no downpipe figure. Ask for downpipes as a separate line on the quote.
What changes the price
- Material. Flood Roofing prices PVC at $40 to $80 per metre and Coloursteel or aluminium at $70 to $120. Copper starts from $150 per metre. Clear Water Spouting in Christchurch says steel is almost the same price as PVC and tends to last longer, so the gap may be smaller on your house.
- Profile size. Impact Roofing Solutions in Auckland runs from about $50 per metre for a standard Coloursteel profile to about $150 per metre for larger commercial profiles, plus GST. It places Marley uPVC between those two figures.
- Storeys and access. Flood Roofing says a two-storey house costs $7,000 to $12,000 or more, and adds $500 to $2,000 if scaffolding is needed.
- Fascia condition. Rotten fascia behind the old spouting has to be fixed before new spouting goes on. Flood Roofing lists fascia repairs as an add-on.
- Removal. Flood Roofing puts removal and disposal of the old spouting at $200 to $500. Check whether your quote includes it.
- Labour. Flood Roofing says its labour rates are $60 to $120 per hour.
- GST. Impact Roofing Solutions quotes plus GST. Flood Roofing and the cleaning sources do not say, so ask.
A worked example
Using the figures above, take a house with 40 metres of spouting. The 40 metres is an assumption for this example. Measure your own house or ask the tradie to.
- PVC at Flood Roofing’s $40 to $80 per metre: 40 x $40 = $1,600 to 40 x $80 = $3,200.
- Coloursteel or aluminium at $70 to $120 per metre: 40 x $70 = $2,800 to 40 x $120 = $4,800.
- Removal of the old spouting, if not already included: add $200 to $500. PVC becomes $1,800 to $3,700. Metal becomes $3,000 to $5,300.
- Scaffolding for a two-storey house, if needed: add $500 to $2,000.
- At Impact Roofing Solutions’ Auckland rates of $50 to $150 per metre plus GST: 40 x $50 = $2,000 to 40 x $150 = $6,000, which is $2,300 to $6,900 with 15 percent GST.
If a quote for this house is far outside these ranges, ask the tradie to explain what is in it.
Rules, licences and consents
Building consent. Replacing spouting does not usually need one. MBIE’s exemptions guidance (January 2026) explains exemption 1 of Schedule 1: replacing a building product or assembly with a comparable one in the same position. It excludes components that have failed the Building Code durability requirements, and sanitary plumbing and drainlaying. We did not find a page that names spouting specifically. A different system, a change of layout, or a new connection to stormwater may be treated differently, so ask your council if you are unsure.
Licensing. Replacing spouting alone is not described as restricted building work in the council guidance we read, which names wall and roof cladding systems under weathertightness. If the job also involves the roof cladding or fascia and soffit weathertightness, ask whether a Licensed Building Practitioner is needed, and check the public register at lbp.govt.nz. Connecting downpipes to the stormwater drain can bring in a drainlayer, so ask who does that part.
Working at height. WorkSafe has guidance on working on roofs and says controls need to match the risk. Its FAQ says scaffolding or a harness is unlikely to be needed for low-risk, short-duration tasks. A two-storey eave is a different job. WorkSafe notes the guidance has not been updated for the Health and Safety at Work Act 2015 (page last updated 23 August 2017). Ask the tradie how they will work safely on your house, and be wary of anyone working on a two-storey eave with a ladder alone.
Asbestos. WorkSafe says homes built before 1 January 2000 may contain asbestos. It says asbestos can be found in gutters, downpipes, gables and eaves, and the only way to confirm is a sample from a reputable contractor. If your house is older, ask whether the spouting has been checked before it is cut or broken.
Written contract. MBIE says a written contract is required for residential building work costing $30,000 or more including GST. Spouting alone rarely gets there, but written quotes are a good idea at any price.
Questions to ask before you say yes
- Does the price include taking off the old spouting, new brackets and downpipes?
- Is the fascia behind the spouting checked, and what happens if it is rotten?
- Is it one long run or joined sections, and where are the joins?
- Is scaffolding or other access gear in the price, especially on a two-storey house?
- Where does the water go at the bottom of each downpipe?
- Is GST included in this figure?
- Is my house old enough that the spouting could contain asbestos?
