Insulation Replacement Perth
Refresh Your Roof Cavity, Attic & Loft — Remove the Old, Bring in the New
At Megatec Roof Insulation Solutions, our insulation replacement service takes care of your roof, ceiling, roof cavity, attic, or loft by removing worn or contaminated insulation and installing fresh, high-performance insulation batts. Over time, old, soiled, dusty, or smelly insulation — especially if it’s blown-in or paper-based, or degraded fibreglass batts — can become damaged or infested by rodents like rats. Our replacement service restores your roof space to safe, efficient, and long-lasting form.
Why Replace Your Insulation?
You should consider insulation replacement when:
- Your current insulation is old and dirty and no longer effective.
- Your current insulation is compressed and ineffective.
- You notice sagging, discolouration, or areas that look damaged on your ceiling.
- There’s a persistent smell coming from your ceiling or roof cavity — often a sign of rodent or rat activity.
- The insulation is the dusty, soiled, or compressed type (especially blown-in or aged batts).
- You suspect there was a rodent infestation — rats nesting or nesting material shredded inside.
- Allergy symptoms, respiratory issues, or poor air quality could be caused by contaminated insulation.
- Your current insulation no longer offers proper thermal protection.
- You want to improve your home’s thermal performance and make it more Cool and Cosy.
- Your current insulation is below today’s recommended R-rating.
Our Insulation Replacement Process
Here’s how we do it, safely and thoroughly:
- Full Inspection
- We access your roof cavity, attic, or loft and inspect the existing insulation — checking whether it’s blown-in, paper-based, or fibreglass batts.
- We identify rodent damage, signs of rats, soiling, odours, and any structural issues in your ceiling or roof support.
- Safe Removal of Contaminated Materials
- We remove all old, soiled, or damaged insulation.
- Using industrial vacuum systems, we extract dust, rodent droppings, nesting materials, and debris without contaminating your living space.
- If the insulation has been compromised by rats, we carefully bag it to prevent the spread of contamination.
- Cleaning & Sanitisation
- After extraction, we thoroughly vacuum the entire roof cavity, attic, or loft to remove dust and remaining contaminants.
- We treat the space as needed to neutralise odours from soiled insulation or previous rodent presence, ensuring the area is clean and safe.
- Professional Installation of New Insulation
- We install top-grade batts – either fibreglass batts or other modern options that suit your home’s needs.
- Our batts are laid carefully between joists, ensuring even coverage across ceiling, attic, and roof cavity — no gaps, no compression.
- We make sure insulation is correctly positioned around wiring, light fixtures, and tricky corners to maximise thermal performance.
- Final Check & Advice
- We perform a final inspection to confirm everything is installed properly — and that there’s no evidence of ongoing rodent activity.
- We advise on pest-prevention measures (entry-point sealing, baits, etc.) to help keep rats or others out in the future.
- We can also recommend how to maintain your insulation to keep your home Cool and Cosy and running efficiently.

OUR PERTH CLIENT TESTIMONIALS
“I found these guys after reading a forum about insulation removal. They were the most recommended company on the forum because of there honesty, integrity and workmanship. I can now add that I 100% agree with what others said about Megatec roof insulation solutions.”
“My partner and I spend hours researching insulation removal companies that can also deal with possums and rodent issues and were 100% satisfied that we chose the right one. Thanks Chantal, Dan and the crew for your thorough service. We needed the 400 square meter soiled “blow in” insulation to be sucked out within a couple of days before roof renovations. Was no problem for these guys. They were quick and tidy leaving no mess. Even having Colin come over and have a business minded chat was great. All the best with the new venture” .
“Was very happy with the services I received from Megatec roof Insulation. They were fast, affordable and more importantly efficient. Dan and Tanner explained the process, including the possum proofing and gutter guard installation, what to expect from the new insulation and the performance is everything they said it would be. We will recommend MRIS to anyone”.
“I highly recommend Megatec Roof Insulation solutions, I had them remove the old messy batts, vacuum the attic and install new hypogenic batts, and they did an excellent job, they did everything in one day and were reasonably priced. From the booking with Chantal and Dan and his crew was easy to work with, if u want insulation ring them for a quote first. Great job mate.”
“The Best experience I’ve ever had with a tradesman. Honest, reliable, competitive pricing. Dan has helped me with my own personal issues regarding dodgy work from tradesmen in the past, even fixed a leaking roof section. His honesty and service was second to none and am more than willing to recommend MRIS as a fair dinkum business.”
“After a fantastic job and compliments from my ceiling fixer, electrician and air condition guy I had to jump on board and say that Megatec Insulation Solutions did a very professional job.”
“Many thanks to Dan and his crew for the excellent and extremely cost-effective removal of old stinky formaldehyde insulation and installing new of Bradfords Gold batts R4.1 the other day. Definitely a lot better than the $7,500 quote I received from some other installer, which I promptly consigned to the rubbish bin. They were on time and done in a day as promised. The difference is not unnoticed. House feels cosy again. Im getting them back to do the same to my rental in Freo and I know that they will do another superb job. Peace of mind guaranteed. Thanks MRIS.”
“I was reluctant at first to remove my old blown-in insulation because I read on the Internet that some companies charge $6000+. These guys did the job much cheaper and overall I was happy with the end result.”
“Thanks to Tanner & crew, thanks for the efficient and no hassle job you did removing the old Wool and installing the new Bradfords batts. We liked that Dan is truly knowledgeable regarding the pest problem and the insulation. Thanks for spending the time going through all the pros and cons of all the different insulation types. Thanks for getting rid of the rats in the roof, my wife can sleep in peace now.”
“Megatec roof insulation solutions was great to deal with. I recently had the cellulose vacuumed/ removed and new batts replaced in my roof. The house is already cooler! Dan was quick to respond, was on time, spend time assessing the roof work, quote and came in under half of the other ridiculous quotes I received! I work away however, organising the job was completely hassle free. Tanner the crew lead even went as far as to remove some extra insulation that was over the garage, free of charge. Highly recommend these guys. Reliable, efficient, tidy and reasonably priced. All the things we need and expect in a tradesman! ”
“Employing the services of MRIS was the best thing we ever did. Not only has the new insulation made such a positive impact on our home, but I cannot speak highly enough of the service that they provided. They were punctual, reliable and honest which are qualities many companies lack these days. They gave us an excellent price, quality service and Dan and his staff worked extremely hard to finish the job in incredible heat. I can also say the possums has also not come back after the possum proofing they did. I cannot recommend them highly enough.”
“Megatec Insulation are an excellent example of a business which show true professionalism in the trade industry. Not only did MRIS show up on time, quote a competitive price, communicate the entire process of insulation removal & install works to me, but were also highly informative, honest and did a fantastic job. We had our old cellulose insulation removed and installed Bradfords insulation which was recommended. I noticed the difference straight away and have since avoided running our A/C all day. Initially we were running our a/c for 8 hrs during the day with the old blown in insulation but now only run it for 1hr. I have since climbed into my roof cavity to store a few household items and am always impressed at how neat the insulation was installed. can’t recommend these guys enough.”
