Great Product and Great service. I use DIY for all my gutter guard jobs and continue to recommend them to others. You wont find better than these guys.

Fantastic system and excellent customer service. I must admit, I didn't pay close attention to my initial order and had actually ordered the wrong system from my roof. Luckily Brenden prior to dispatching the order realised what I'd ordered was not common. He rang me up straight away and we were able to diagnose my mistake and get it corrected. I even managed to pay less as a result. I have no hesitation in recommending these guys for ensuring you get the right system for your roof, and quickly. It was literally overnight from Melbourne to Brisbane.

Fantastic experience with Aussie DIY Solutions. Jeremy and Brendan were both excellent and answered any questions that I had. The gutter guard is great quality and matches my roof colour really well. Great price too. Would happily buy again!

This is the first time I have installed this type of gutter guard and I must say I am very impressed. The quality of the product is top notch and very easy to install. Very easy ordering process and I received my 3 kits to Brisbane in 3 days. I would definitely purchase again.
I have recently purchased my second order from Aussie DIY Solutions. The experience was first class. I had made an error in my first order early this year and the consultant was extremely helpful in helping me sort this. A minimum of fuss and a cash adjustment and all was good. The second order arrived very quickly. Great service.

Product was delivered pretty quickly and everything was well packed, the mesh is good quality and pretty easy to work with just gets a bit fiddly lifting the tiles and tucking the mesh under, i was doing the job myself but with 2 people it would be easier After i did the whole back gutter i got the hang of it. The strips that hold the mesh firm onto the gutter are a great colour match like the mesh and easy to work with, i fixed to the gutter first then tucked mesh under the second row of tiles then did silicone around the ridge capping last. All up im very happy with the quality of the total package, the mesh, strips, and screws, also the wider 1 metre valley mesh is a must to get the span you need to cover the vally properly and lastly its not that hard for the people out there that like to do things themselves. I recommend this product and glad i went with Aussie DIY

I have just used this firm for the first time and the experience has been nothing but positive, The price and quality of the product were great and Jeremy was very helpful both in helping me formulate the order and also in some installation advice when I encountered difficulties due to the location of a solar array on my tile roof. The order was also despatched quickly and arrived faster than the freight company's predicted ETA. I look forward to using Aussie DIY again for a couple of other projects later this year.

Great services. I contacted them by phone, and Jeremy was so helpful. Delivery was done in no time and perfectly package. In terms of product, I ordered gutter protection for all my house and sheds (130ml). Very easy to install, and looks awesome. I think the worse part is to clean the gutters before installing but very rewarding when thinking that will be no longer necessary to go into the gutters again!
Response from the owner:Hi Carolina thank you for taking the time to leave a review. I’m glad you liked the product, and had a great customer service experience with Jeremy.

I have a 4 bay shed and the gutters were getting continuously filled with leaves and sticks from the large gum tree in the neighbours yard. Cleaning the gutters was a lot of work as the downpipes would get clogged as well. I fitted this product back in 2020. Since then the gutters are staying clean. The rubbish now blows or flow over onto the ground. So it is much easier to just rake this up from time to time. Very happy with the the result and installation is straight forward.
Response from the owner:Hi Peter thank you for taking the time to leave a review. I’m glad you liked the product, and the gutter guard is performing well for you.
Great products and super quick postage Thank you and will definitely recommend

Great service and spoke to a real person. I think their how to videos can be better quality and their written instructions should match the video. All that said the gutter guard was easy to install and the quality appears to be good, time will tell.
Response from the owner:Thank you Robert for leaving a review. I agree we do need up the quality of our videos ands it’s something we are working on at the moment. I’m glad we where able to help when you called and you are happy with the gutter guard.

Response from the owner:Thank you Justin for taking the time to leave a review. It’s great to get rid of pigeons and pleased to know your gutter guard arrived quickly.
Casey Hamilton

We have a low angle slope on our roof and a high lip on our gutter so I wasn’t sure if the gutter guard would work as it might create a ‘valley’ where the roof meets the mesh. I rang and spoke to Justin (?) and he gave some great advice and suggested we get a custom width to help minimise the issue. There was no extra cost for this and the product arrived fast and was super easy to install. Really happy with the quality and so relieved I don’t have to get on the roof every few weeks to clean 32m of gutters!
Response from the owner:Hi, Casey thanks for taking the time to leave a review. We are always more than happy to help and answer questions to find the right solution for you.

TOUGH PROTECTION FOR AUSSIE HOMES

Wall Cavity Closer Mesh Built for Australian Conditions

Standard brickwork and cladding systems rely on open wall cavities to breathe, but these gaps present a major vulnerability. Without physical protection, they act as direct pathways for embers during bushfires and entry points for destructive pests.
Our heavy-duty, corrosion-resistant closer mesh is engineered to meet strict Australian Standards (including BAL-40 and BAL-FZ requirements). It allows essential airflow for moisture control while acting as an impenetrable shield. Easy to cut and install, it’s the professional builder’s choice for simple, reliable DIY bushfire and pest mitigation.

What is cavity closer mesh?

Cavity closer mesh is a tough, durable metal screen installed at the base of wall cavities. It prevents external hazards like fire embers and vermin from entering the structure while safely allowing water vapor to drain and air to circulate through weep holes.
For BAL-29 (Bushfire Attack Level 29) compliance under AS3959, the mesh must act as a physical barrier to ember entry. Our BAL-29 compliant options feature steel or bronze construction with maximum aperture openings under 2mm to prevent floating embers from settling in wall cavities.
BAL-40 mesh is engineered for high bushfire risk zones. It is manufactured from robust, non-corrosive Grade 316 stainless steel with a specialized high-density weave. This ensures superior resistance to structural radiant heat and direct ember impact.
Our mesh is precisely designed to allow wall cavities to breathe. The micro-apertures maintain an optimal balance, providing a heavy-duty physical block against embers while ensuring high open-area percentages for continuous natural airflow and mold prevention.
Yes. The premium-weave high-tensile metal wire acts as an impenetrable barrier. It successfully blocks rodents, nesting birds, wasps, and larger insects from entering wall cavities or structural gaps, safeguarding your home from pest-related damage.
We stock standard roll widths to match typical Australian wall cavity profiles (including 50mm, 75mm, 90mm, 110mm, and 150mm). Our rolls are easy to handle for both DIY builders and large-scale commercial framing installs.
Yes, we ship directly to worksites, depots, and residential locations all across Australia. All shipments are packed professionally to prevent transit damage, ensuring your mesh arrives flat, clean, and ready for immediate deployment.
