After having professional attic cleaning services, I noticed one rather rude guest still hanging around: the cold. That chilly surprise sent me searching for the best spray foam insulation in Auckland.
Spray foam seals awkward gaps where draughts and dampness love to sneak in. It can make your home feel warmer while helping keep energy bills from running wild.
So I’ve looked into Auckland installers that understand local homes, building requirements, and our famously changeable weather. Here are the top picks for giving your property a cosier all-year upgrade.
How much does spray foam insulation cost in Auckland?
The cost of spray foam insulation in Auckland is around $40–$100+ per m². A standard 100m² home cavity usually costs $4,000–$7,000. The final cost depends on the type of foam and the specific installer’s rates.
Below is a breakdown of estimated costs based on the type of foam:
Open-cell foam costs $40–$65 per m².
Closed-cell foam costs $70–$100+ per m².
1. NZ Application Service Limited

Area served: Auckland, NZ
Contact: 027 304 9784 | 021 797 487
Hours: Monday-Friday, 7 AM – 3 PM
I had NZ Application Service spray my workshop last winter, so I know firsthand how quickly their mobile rig gets to work. The setup was impressively fast, which is exactly what you want when Auckland’s weather is plotting against your building.
NZAS offers closed-cell foam for strong thermal and moisture resistance, plus open-cell foam for cavity filling and sound absorption.
Their services cover residential, commercial, industrial and marine projects. This gives them plenty of room to tackle more than a chilly ceiling.
The company brings decades of experience and works with CodeMark-certified products or systems. I’d still ask which product and certification apply to your project before the foam starts flying.
The main limitation is scheduling. Weekday hours finish at 3 PM, and the team is closed on weekends, so after-hours or Saturday jobs aren’t on the menu.

Campervan Spray Foam Insulation Results
Used these guys to spray foam insulate a van for camper conversion. The results are amazing! If you’re thinking of doing a campervan build, this is the way to go. Very quick, effective insulation and vapour barrier, no smell, and cost-effective. Highly recommend.

2. Insulfoam

Address: 62 Beaumonts Way, Manurewa
Contact: 0272 478 902 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM
I like a family-run crew where you can tell who’s holding the hose and who’s answering the phone. Insulfoam keeps things close to home, with Andrew family members covering application, sales and stock management.
Ross Andrew leads the team and brings more than 30 years of construction experience, along with qualifications from Huntsman Building Solutions in Texas. That’s a useful mix of hands-on experience and foam know-how.
Their open-cell foam uses soybean oil and recycled plastic, while the company says it contains no ozone-depleting chemicals.
Insulfoam can pair the installation with a heat-recovery system, and advertises a lifetime warranty for extra peace of mind.
The main drawback is scheduling. Office hours run from 9 AM to 5 PM on weekdays, with no weekend hours listed. Saturday project chats may need to wait.
3. LJ Insulation & Coatings

Area served: Kaitaia, Whangarei, Kerikeri, Mangawhai, Auckland
Contact: +64 21 0227 8349 | [email protected]
Hours: Monday-Friday, 7:30 AM – 5:30 PM
When a building problem refuses to behave, I like a contractor willing to investigate before reaching for the foam gun. LJ Solutions began by tackling commercial remediation projects where downtime was about as welcome as a leaking roof.
The team assesses the substrate, ventilation, access and required performance before recommending a system. That measured approach is reassuring when one magic material clearly won’t suit every building.
LJ offers closed-cell spray foam, open-cell options, plus injection and pour foam for selected cavities.
Its 50-metre heated hose has helped reach awkward areas at a Te Arai Links project without parking a giant truck beside the house.
The main catch is the access requirement. Residential underfloor spraying needs at least 700mm of clearance, which may rule out some older homes.

Professional Camper Spray Foam Service
I had this company spray foam my camper for our winter escape next season, and boy oh boy, what a fantastic product and experience! Super professional and very knowledgeable about what product is best suited for the job. What was surprising is that they also offer a Rhino lining product that I’m having them spray next month to complete the project. Thanks again, team; you’re a one-stop shop!!

4. Refresh Renovations

Address: Garnet Road, Westmere
Contact: 0800 33 60 33
Hours: Monday to Saturday, 9 AM – 5 PM
Renovating without a plan can turn your weekends into a full-time admin job. Refresh Renovations keeps the process tidier with a dedicated consultant acting as your single point of contact.
A friend used their Auckland Central team last spring and found the communication refreshingly smooth.
Their five-step process covers consultation, design, costing, construction and completion. This is helping ensure fewer details disappear into the renovation fog.
Refresh can coordinate insulation through its trade network, offering options such as spray foam, fibreglass, pink batts and eco-friendly materials. You don’t need to commit to a full makeover either, as standalone insulation work is available.
The main catch is the franchise structure. Your address determines which consultant handles the job, and Sunday closure means weekend planning is limited to Saturday appointments.

5. Highgrade Coatings Limited

Address: 27 Stonedon Drive, East Tāmaki
Contact: 021 959 069 | [email protected]
Hours: Monday-Friday, 7:30 AM – 4 PM
I appreciate contractors who know their foam from their fluff, especially when the project involves more than a chilly ceiling. Highgrade Coatings brings 30 years of New Zealand spray-foam experience to specialised insulation and coating work.
Its polyurethane foam expands to approximately 30 times its original volume, creating a continuous layer that can help manage air leakage and moisture.
The company handles containers, tanks, pipes, marine applications and coolstore sheds where awkward surfaces make ordinary insulation less practical.
Highgrade’s injection systems suit selected enclosed cavities, while spray applications cover prepared exposed surfaces. That makes the team particularly useful for commercial, industrial and specialist projects that don’t fit neatly in a DIY handbook.
The main drawback is residential wall retrofits.
Highgrade won’t inject foam into pre-existing residential walls because expansion pressure could cause damage, so blind cavity upgrades require another solution.
