The 5 best insulation providers in Sydney you’ll want to hire for your next project
We all want a warm environment during the cold season and a cool one when the heat comes. Wouldn’t it be nice if your house could do that automatically without raising your electric bill or needing to plug in and press a button?
That’s exactly what insulation does. And it doesn’t stop there—it can also help block out noisy neighbors or the rumble of their car as they pass by, and even muffle sound between rooms, so things feel a lot more peaceful.
If you’ve long been planning to insulate your space but aren’t sure where to go for installation or materials, why not check out some of the best insulation providers in Sydney? Homeowners and builders have been relying on their thermal and acoustic solutions for years!
| How much do insulation providers charge in Sydney? Insulation providers in Sydney typically charge $2,800 to $5,500 for a standard home. Factors affecting the cost include the type of insulation (fiberglass, polyester, rockwool, or spray foam), area to be insulated, labor fees, and installation complexity. |
1. Sydney Insulation
Address: Unit 1/4 Powdrill Rd, Prestons
Phone: +61 2 7233 1266
Business hours: Monday-Friday, 8:00 AM to 4:00 PM
Sydney Insulation’s team of 70+ highly trained professionals has installed insulation in over 15,000 Aussie homes. Most homeowners remember them for the great communication from the initial quote to completion, on-time service, and competitive pricing.
With EarthWool Batts, Supafil Carbon Plus, and Fletchers Batts in their lineup, it’s clear they work only with trusted insulation brands in Australia. It’s no surprise commercial builders choose them, too—thanks to the wholesale supply deals that get delivered straight to the site.
While their roof, ceiling, wall, and underfloor insulation receive a lot of praise, the crew’s acoustic noise reduction has let down some clients. In one case, poor planning and execution due to inexperience with a stud wall left behind a dusty apartment and badly patched holes.
Still, customers keep coming back because they also remove old insulation and vacuum ceilings. Plus, they’re certified polyurethane insulation applicators—that’s spray foam insulation that helps cut down on energy use.
Excellent job and price was very competitive
“With the dense and hard to compress bats, fitting them through an extremely small manhole, Zaf and the team were able to get it to the roof edges as far as possible in the low pitched roof. Working with Josh during the quotation was fantastic too! Excellent job from the team, price was very competitive and would highly recommend!”

Professional, punctual, and completed the job efficiently
“We recently had our roof insulated by Sydney Insulation and the experience was excellent. The team was professional, punctual, and completed the job efficiently. The insulation has made a noticeable difference in maintaining indoor temperature. Highly recommended for quality service and results at a competetive price.”

2. 4 Seasons Home Insulation
Address: 1 Macquarie St
Phone: +61 1300 331 366
Business hours: Monday-Friday, 7:30 AM to 5:30 PM
Many residents felt a real difference in their homes after 4 Seasons finished installing their insulation. One house stayed noticeably warmer through a single-digit cold Sydney night, while another benefited from improved comfort during extreme summer heat.
Packages include: Top-Up (Roof) for $150, Sweet Spot (Roof + Underfloor) for $250, and Love Your Home (Roof + Wall + Underfloor) for $500. All use certified Australian-made products like Woolcell, Insulbloc, and Cellulose Mulch—loved by clients for their quality and local roots.
Customer service gets recognition, too, for being clear, helpful, and quick to send someone out when needed. Meanwhile, the installers are described as friendly, knowledgeable, and skilled at handling tight spots.
However, a handful of clients encountered workers who didn’t clean up—leaving old insulation on driveways or near front doors. Other times, there were black marks on the walls and dust covering personal items like boxes, bicycles, and tools in the garage.
House now stays noticeably warmer all night
“I had my house treated by spraying in the Woolcell insulation to an R4 standard by Doug and the team. My roof had a poor installation of batts and the heat would quickly be lost once the heating was turned off. The installation was issue free, and my house now stays noticeably warmer all night even when the temperature drops to the low single digits on a cold Sydney night. I found Doug to be very helpful and easy to deal with, and my only regret is not having the insulation done earlier.”

Informative sales and comprehensive work in tight spots
“Firstly the sales guy who came was very informative and provided some useful education. The quote was reasonable. They sent 3 guys for the install and it took 2 days. How these guys were able to install insulation in some areas I am just unsure about as there are some really tight spots. Yet having inspected the work myself at close quarters – as most of us will never actually go under there after it’s done – I can say these guys are really comprehensive and this gives me a lot of trust in them for the next job when we want to do the ceiling.”

3. Patnicar Insulation
Address: Unit 5/18 Bluett Dr
Phone: +61 2 4655 8488
Business hours: Monday-Friday, 8:00 AM to 4:00 PM
At Patnicar Insulation, you can choose to go DIY and simply buy the materials or book a full installation instead. Either way, many clients plan on coming back for future projects because of the team’s assistive, well-organized service and quality products.
Among the products you can shop online or have installed are ceiling batts from $44.40, underfloor batts from $51.57, and wall batts from $39.72. They also have acoustic and polyester insulation batts, starting at $46.70 and $61.75, respectively.
Delivery is often fast and smooth, though a few orders have ended up at the wrong address—usually from missed instructions. It helps that even when delayed, packages arrive in good condition and are carefully placed at the doorstep.
Moreover, being certified Bradford Expert Installers gives added reassurance to those who opted for installation. This means the team is highly trained and works to the standards of one of Australia’s top insulation manufacturers.
Friendly, well-organized service
“The service was friendly and well organised. Shout out to the gentlemen who was organising all the pick ups and doing the loading. What a pro. Will be back again.”
- Michael Johansen, Google Review
Smooth process and all done within a week
“Everything went smoothly, from the inspection, to booking the work, and the execution. All done within a week! I happily recommend Patnicar for subfloor insulation.”

4. J and T Insulation
Address: 31-33 Jack Williams Dr, Penrith
Phone: +61 1300 301 331
Business hours: Monday-Friday, 7:00 AM to 4:00 PM
J and T make it easy to get insulation batts for just about everything—walls, ceilings/roofs, floors, and even acoustic, thermal, and fireproof needs. You can let their efficient team take care of the install or simply order supply-only batts, which are ideal for commercial builds.
Service and installation quality impressed many builders, with one even saying they’d gladly hire them again for their reliability and clear communication. Another repeat client also vouched for their consistent professionalism and solid work across multiple builds.
One drawback to consider is their history of missed appointments without prior notice, which understandably caused some frustration. Roof insulation results were mixed, too, as a few residents reported no noticeable change during hotter days.
What makes it better, though, is the wall insulation variety. Clients like being able to choose from acoustic for a quieter space, fiberglass for exterior cavity walls, and polyester for something easy to install, safe, and odorless.
Efficient, reliable, and excellent communication
“We have found J and T Insulation to be an efficient and reliable insulation provider (supply only in our case). Their communication is excellent and we will use their services again.”
- Aaron Jones, Google Review
Professional and always a great job
“We use these guys for all our builds they are professional and always do a great job.”

5. Eureka Insulation
Address: 1/126 Jedda Rd, Prestons
Phone: +61 1800 626 624
Business hours: Monday-Friday, 7:30 AM to 4:00 PM
Eureka Insulation has been installing (and supplying) wall, roof, ceiling, and fire-resistant insulation to both residential and commercial spaces for over 30 years. These come with a variety of options, including industrial, acoustic, or thermal applications.
On top of that, they partner with eco-friendly brands like PerformIns, pro clima, and Earthwool to create their products. They also recycle much of their waste—something that homeowners and builders admire, with one even calling them experts in energy efficiency.
Some customers just wish pricing was more accessible online, especially when trying to gauge affordability while sourcing materials for commercial builds. While quotes are just a call away, not everyone finds the time for that extra step.
The upside is that people continue to trust them for their detailed quotes, reliable delivery times, and responsiveness. Add in how their brand partnerships make it easy to get insulation that fits whatever type, brand, grade, or shape you’re after.
Prompt, professional, and detailed quote
“The entire Eureka team has been amazing. They presented their quote in great detail and in an easy-to-understand way. They are prompt and professional. Their work was excellent. Would highly recommend them.”
