Repair it, or replace it?
We quote honestly both ways and show you the photos, so the call is easy.
A repair is usually enough when
- The duct is loose, torn or disconnected in one spot
- Insulation is dry and in good shape
- The rest of the system checks out during inspection
Replacement is smarter when
- Insulation is mouldy, soaked or crushed
- The system leaks in more than one place
- Ducting is aged and failing section after section

Recent duct repairs across Melbourne
Inspection + minor repair Uneven heating from a disconnected duct
A duct join under the floor had sagged and pulled away, so heat escaped before the bedrooms. We rejoined, sealed and strapped it back up.
The system was overworking while key rooms stayed cold, wasting energy every day it ran.
Airflow restored across every room.
“A simple fix, but it needed the right hardware. A proper joiner, strong tape and a strap is the difference between a quick patch and a lasting repair.”Technician’s note
Inspection + targeted replacement Corroded duct with rodent contamination
A dead rat had corroded the duct lining and soaked the insulation. We replaced the line with new Metalflex duct and sealed every join.
Rodent contamination is a health risk once air circulates, and the leaking duct was driving up energy use.
Odour gone and the air healthy again.
“Once you find something like that, replacement is the only safe option. That duct was beyond cleaning, it had to go.”Technician’s note
Inspection + full replacement Mould-contaminated, leaking ductwork
Mould, degraded insulation and leaking joins under the home. We removed it all and installed new insulated ducting, sealed properly.
The system was circulating unhealthy air, leaking heat and drawing in dust and moisture. A clean would not have fixed it.
Clean air and even heating restored.
“Mould inside ducting is never something to ignore. Once it has eaten into the insulation, the only real fix is a full replacement.”Technician’s note
$150 inspection fee waived with a full duct replacement
If your ductwork is beyond a basic repair, we replace it with insulated Metalflex Bradflo ducting and waive the $150 inspection fee. You only pay for the work that matters.
Save $100 when you book your duct inspection together with a duct cleaning.

Jason did a fantastic job, I would definitely recommend him again. He took his time and pointed out some stuff about the house I was not aware of.
Leon from Mr Duct did a great job of getting our ducts back in order. Arrived on time, and was very professional. Thanks Leon and Mr Duct!
Extremely detailed and provided lots of useful information to maintain the system day to day. Highly recommend.
Duct repair FAQs
How do I know if my ducts need repair?
Weak or uneven airflow, high power bills, noisy vents, or dusty or musty air are the common signs. A quick inspection confirms it for sure.
How long does a duct repair take?
Most repairs are done in a single visit. Bigger jobs or full replacements can take longer, and we tell you what to expect in the quote first.
Will duct repair reduce my energy bills?
Usually yes. Sealing leaks and reconnecting ducts stops conditioned air escaping, so your system runs less to reach temperature.
Do you repair all types of ductwork?
Yes, gas ducted heating, evaporative cooling and ducted air conditioning, both ceiling and underfloor, across Melbourne.
Is your duct repair work guaranteed?
Yes. Every repair is backed by our 7-year workmanship warranty.
Can I repair the ducts myself?
You can tape a small split as a stopgap, but most damage sits in ceiling or underfloor spaces where it is hard to reach and easy to miss. We find every fault, use proper materials rather than tape, and back the work with our warranty.
How urgent is a duct repair?
The sooner the better. Every week a leak runs, you pay to heat or cool air that never reaches your rooms, and open ducts can draw dust and damp air in from the roof or subfloor. An early inspection usually means a smaller fix.
Can you fix ducts in tight or hard to reach spaces?
Yes. We regularly work in subfloors, roof cavities and tricky ceiling spaces. It can take a little longer, but we bring the right tools, lighting and gear to do the job properly.
Is duct repair messy?
No. Any ceiling panels we move are resealed, disturbed insulation is put back properly, and we clean up the work area before we leave.
Should I repair or replace my ductwork?
If the ducting is loose or torn in one spot, a repair usually does the job. If the insulation is mouldy or crushed, or the system leaks in several places, a duct replacement is the smarter long term fix. We quote honestly both ways.
