Google: 4.9 / 5 · 393 reviews · 29.9 km from search centre

Earthwool Insulation
Google: 4.8 / 5 · 4 reviews · 6.6 km from search centre
AI-assisted analysis of public reviews:
The review sample is very thin, but the comments that are there are positive about the product itself and technical support. One reviewer mentioned ending up buying elsewhere, so there is not much service pattern to judge from these excerpts.
Total Insulation
Google: 4.5 / 5 · 20 reviews · 10.9 km from search centre
AI-assisted analysis of public reviews:
Reviews point to helpful staff, good explanations, and crews that are professional, accommodating, and tidy on site. Several customers also mention noticeable temperature or noise improvements after installation.
Insulation Guru Brisbane
Review noteGoogle: 4.8 / 5 · 52 reviews · 31.3 km from search centre
AI-assisted analysis of public reviews:
Positive reviews mention prompt quoting, strong communication, and solid workmanship from specific staff members. But the supplied feedback is mixed overall, with several reviewers raising concerns about extras, delays, cleanup, and follow-up.
Roof Suckers
Google: 4.8 / 5 · 50 reviews · 12.6 km from search centre
AI-assisted analysis of public reviews:
Customers often highlight fair pricing, easy communication, before-and-after photos, and strong results after old insulation removal and replacement. Reviews also suggest the team is responsive if post-job issues are raised and generally leaves sites very clean.
Knauf Insulation
Review noteGoogle: 4.3 / 5 · 15 reviews · 6.6 km from search centre
AI-assisted analysis of public reviews:
The limited review sample leans more toward product satisfaction than installation service, with praise for underfloor and blanket products being effective and easy to handle. One recent review does flag a poor interaction, so the service experience may be less consistent than the product comments suggest.
Insulhome
Google: 5.0 / 5 · 4 reviews · 21.9 km from search centre
AI-assisted analysis of public reviews:
There is very little review detail here, but the available comments describe the business as professional, efficient, and easy to recommend. With only a handful of reviews and sparse text, buyers should treat this as light evidence rather than a full pattern.
Altitude Insulation
Google: 4.9 / 5 · 67 reviews · 0.0 km from search centre
AI-assisted analysis of public reviews:
Reviewers repeatedly mention quick, clear communication, prompt quoting, and a smooth install process. Customers also praise respectful workmanship, before-and-after photos, fair pricing, and an immediate difference in indoor comfort.
GI Building Sciences
Google: 4.8 / 5 · 9 reviews · 24.1 km from search centre
AI-assisted analysis of public reviews:
The small review set suggests friendly service and a willingness to help when product quantities fall short. Most comments are about the product being easy to work with rather than a large body of installation feedback.
Spray Foam Australia - Brisbane
Google: 5.0 / 5 · 23 reviews · 10.8 km from search centre
AI-assisted analysis of public reviews:
Reviews consistently praise professionalism, tidy work, responsiveness, and strong thermal or acoustic improvements after installation. The sample also suggests good follow-up and an easy customer experience from booking through completion.
Access Insulation
Review noteGoogle: 3.2 / 5 · 26 reviews · 21.7 km from search centre
AI-assisted analysis of public reviews:
The review picture is mixed, with some customers praising friendly staff, fast work, and solid service. However, the supplied negatives raise concerns about workmanship checks and overall confidence, so this is one to review closely.
Peter the Possum Man
Google: 4.8 / 5 · 634 reviews · 3.8 km from search centre
AI-assisted analysis of public reviews:
Customers often praise the team for being professional, knowledgeable, and clear in their communication across more complex roof-cleanout and insulation jobs. Reviews also suggest they are thorough, good at diagnosing problems, and trusted even if not always the cheapest option.
Solutions Built
Google: 5.0 / 5 · 1 reviews · 2.5 km from search centre
AI-assisted analysis of public reviews:
There is not enough review text here to say much beyond the single 5-star listing signal. Buyers would need to do extra checking because the supplied evidence is essentially empty.
Snug and Sound
Google: no rating · 0 reviews · 8.0 km from search centre
AI-assisted analysis of public reviews:
There are no review excerpts and no visible review count to work from here. That makes this listing hard to compare on customer experience against more established Brisbane options.
Cross-Review AI Analysis
What locals are saying in Brisbane
AI-powered analysis of all of the customer reviews from multiple suppliers in the area.
Across Brisbane, the strongest-reviewed insulation providers are being praised for fast quoting, clear communication, punctual arrivals, tidy cleanup, and visible comfort improvements after the work. Several of the better-supported listings also mention before-and-after photos, which seems to matter to customers for roof-space jobs they cannot easily inspect themselves. Removal of old insulation, vacuuming roof cavities, and coordinating with other trades come up as positives for a few businesses, suggesting buyers value end-to-end handling rather than just installation. The market looks fairly competitive at the top end, with multiple businesses carrying high ratings and meaningful review volume. The weaker patterns are mostly around follow-up, surprise extras, inconsistent arrival timing, and workmanship needing to be checked or redone. A few listings have very sparse review text, so they are harder to assess beyond the headline rating. Overall, Brisbane buyers appear to reward firms that communicate clearly, show up as promised, and leave the site clean.

Local questions in Brisbane
Based on the supplied reviews, Brisbane Insulation, Outback Insulation Brisbane, Roof Suckers, Altitude Insulation, and Peter the Possum Man have the clearest positive patterns and enough feedback to support a shortlist. Reviewers for these businesses repeatedly mention communication, tidy work, professionalism, and noticeable temperature improvements. Brisbane Insulation and Outback Insulation Brisbane stand out especially for review volume as well as consistency.
Outback Insulation Brisbane and Brisbane Insulation are repeatedly praised for prompt quoting, clear communication, and arriving on time. Altitude Insulation also gets consistent mentions for quick, clear contact and smooth organisation. Roof Suckers appears strong here too, with several reviews describing the team as easy to deal with and responsive.
Yes — cleanup is a recurring praise point for Brisbane Insulation, Outback Insulation Brisbane, Roof Suckers, and Spray Foam Australia - Brisbane. Reviews mention vacuuming old material, leaving no rubbish behind, and using protective sheets where needed. For roof-space work, that is one of the clearest quality signals in the supplied feedback.
The main risks in this set are surprise fee disputes, slow or incomplete follow-up, inconsistent attendance, and installation quality needing to be checked. Those themes are most visible in the supplied reviews for Insulation Guru Brisbane and, to a lesser extent, Access Insulation. Even where a business has positive feedback overall, it is worth reading the lower-star reviews closely before booking.
Treat small review counts as a weaker signal, even when the star rating is high. Earthwool Insulation, Insulhome, GI Building Sciences, and Solutions Built do not have enough detailed customer feedback here to show a strong pattern on things like punctuality, cleanup, or aftercare. In contrast, businesses with dozens or hundreds of reviews give you a better sense of consistency.
Ask what is included in the quote, whether old insulation removal and cleanup are covered, and how any unexpected site issues are handled. The reviews suggest it is also smart to ask whether they provide photos of completed work, how they manage weather delays, and what follow-up looks like if anything needs fixing. These questions line up with the exact issues customers commented on most.
Yes — Brisbane Insulation, Outback Insulation Brisbane, Roof Suckers, and Peter the Possum Man all have review excerpts that mention old insulation removal along with new installation. Customers liked thorough roof-cavity cleanup, debris removal, and photo evidence of the finished work. That makes them more relevant if your project is a replacement rather than a simple add-on.

Brick veneer versus double brick.
Frequently asked questions
Most brick veneer and double brick homes feature a gap suitable for filling. Solid brick homes do not have this gap, making the service inapplicable. An installer will check for any obstructions before proceeding with the installation.
The most effective insulation options for walls in Australia include expanded polystyrene, mineral wool, and polyurethane foam, tailored to meet your specific needs and conditions.
Your home may feel cold due to several factors such as improper installation, insufficient insulation, or air leaks in other areas of your home that need attention.
Yes, brick veneer walls can be insulated. Installers will blow or pump insulation material into the cavity through small holes drilled in the mortar before sealing them once the job is complete.
The R-value of a typical brick veneer wall ranges from 1.0 to 1.5, depending on the thickness and the type of insulation installed.
Yes, filling the cavity helps to slow down heat transfer through the walls, allowing your home to maintain its temperature with less reliance on heating and cooling systems. The installer will ensure that the cavity is clear and will patch any holes made during the process.
Possible drawbacks include moisture issues if the installation is not done correctly and the necessity of hiring professionals for proper installation.
Yes, even a 50 mm cavity can be insulated by using blown mineral wool or beads, which can be inserted through drilled mortar holes after verifying that the gap is clear.
