Workmanship Guarantee
Last updated: 21 August 2026
We guarantee our installation workmanship for 5 years from practical completion. This page sets out what that covers, what it does not, and how to make a claim. It is provided by Asni 2025 Limited (NZBN 9429052296734) and applies to carpark, basement and podium soffit insulation we have installed.
It covers our workmanship. It does not cover the products themselves. Every system we install carries its own manufacturer warranty, given by the manufacturer and not by us, and those run for different periods on different terms. We hand the relevant manufacturer documentation over with the QA pack at completion so you hold both.
What is guaranteed
For 5 years from practical completion of our work, we guarantee that:
- the insulation remains securely fixed to the soffit, and has not detached, sagged or dropped as a result of how we fixed it;
- the fixing type, pattern, count and edge distances we installed match the manufacturer’s published schedule for the specified product, or the alternative agreed in writing before installation;
- coverage is continuous across the area in our scope, with panels cut and scribed to services rather than left short;
- joints and exposed edges are taped or terminated as the manufacturer’s instructions require for the specified product; and
- the work was carried out in accordance with the manufacturer’s installation instructions and NZS 4246, which is also the condition every manufacturer attaches to its own product warranty.
A product warranty is conditional on compliant installation, so an installation that does not follow the schedule does not weaken the manufacturer warranty, it stops it engaging at all. Guaranteeing our fixing schedule is what keeps yours alive.
Guarantee period
5 years, running from the date of practical completion of our work on the relevant section of the building, or from the date of our final invoice for that work if practical completion is not certified.
Section 393(2) of the Building Act 2004 bars civil proceedings relating to building work brought 10 years or more after the act or omission complained of. Our 5 year guarantee sits inside that period. It does not extend it, and it does not shorten any statutory period that applies to you.
What is not covered
- Damage caused by others after handover. Following trades working in or through the soffit, penetrations cut after we leave, services installed through the panel, and impact from plant, vehicles or scaffolding.
- Failure of the substrate or structure. Movement, cracking, spalling or deflection of the slab, and any consequence of the concrete not being what the drawings said it was.
- Modification or removal by others. Any part of the system cut, re-fixed, removed and reinstated, or added to by anyone other than us.
- Water, fire and impact. Water ingress from any source including leaks, flooding, condensation from a mechanical fault and washdown, and damage from fire, heat or impact.
- Product defects. Defects in the insulation, tape, adhesive or fasteners themselves. Those sit with the manufacturer, and we will help you make that claim.
- Normal wear, discolouration and soiling. Including dust, exhaust staining and fading, none of which is a workmanship failure.
- Work outside our scope. Anything we did not install, and any part of the specification we raised in writing before starting and were instructed to proceed with anyway.
- Performance the product does not have. Thermal, acoustic and fire performance are properties of the specified product. We guarantee that we installed what was specified, correctly. We cannot guarantee a result the specified product was never going to reach.
Making a claim
Email quotes@carparkinsulation.co.nz with the building, the level and location of the affected area, photographs, and the approximate date you first noticed it. If you have our QA pack, quote the job reference from it.
Tell us as soon as you notice a problem. We will acknowledge within 2 business days and inspect within 10 business days of acknowledging, or agree a longer date with you if access needs arranging. Leaving a defect to worsen before telling us can affect what we are able to put right and what it costs, so early notice is in both our interests.
What we will do
Where we agree the claim is a workmanship failure covered by this guarantee, we will re-attend and put the affected area right at our cost. We choose between repairing the affected area and replacing it, and we will tell you which and why before we start.
Our cost covers our labour, our materials and our access equipment. Safe and reasonable access to the area is provided by you or by the building owner, along with any permits, inductions or out-of-hours arrangements the building requires. If the area has become live occupied space and access can only be had at night or in stages, we will still do the work, and we will agree the access arrangement with you first.
This guarantee covers making the installation right. It does not cover consequential loss, including loss of use, loss of income, or the cost of other trades’ work disturbed to give us access.
Transfer
The guarantee follows the building. It is given first to the party that contracted us, and passes to the owner of the building and to any subsequent owner for the balance of the 5 year period.
Whoever holds it, it stays subject to everything on this page. A new owner takes it as it stands, with the same exclusions and the same claim process, and cannot claim for anything that happened to the installation before they acquired the building.
Your other rights
This guarantee is in addition to, and does not limit, your rights under the Fair Trading Act 1986, the Consumer Guarantees Act 1993 where it applies, and the Building Act 2004. Nothing on this page reduces those rights.
Where our work forms part of a residential building contract or the sale of household units, the implied warranties in sections 362I to 362K of the Building Act 2004 apply regardless of anything in this document or in our contract, because section 362H says they apply despite any provision to the contrary in any agreement.
Where the work is supplied and acquired in trade and both parties are in trade, the Consumer Guarantees Act may be contracted out of under section 43 of that Act, but only in a written agreement where all parties agree and it is fair and reasonable to do so. This page does not contract out of anything.
Governing law
This guarantee is governed by New Zealand law and the New Zealand courts have jurisdiction over it.
