Get possums out of your roof and keep them out
One-Way Possum Door Installation
One-Way Possum Door Installation Melbourne gives you a permanent exit for possums living in your roof, ceiling or wall cavity. We fit a spring-loaded possum one-way door over the entry point, so the animal leaves at night to feed and cannot get back in. If you hear scratching above the bedroom at 2am, we can inspect today.
What's included
What Our Possum Door Installation Includes
Every one-way possum door installation includes the door, the fittings, the sealing of secondary entry points and a follow-up inspection. We quote the whole job upfront so there are no surprises.
Full roof inspection
We check the roof, eaves, wall cavities and chimney with a roof ladder, torch and inspection camera. You get a written summary of every entry point we find, including secondary holes that need sealing.
One-way door fitted
We supply and fit a spring-loaded one-way possum door over the main entry point, fixed with timber battens and steel fixings and sealed with silicone sealant. The door is strong enough to handle a large brushtail possum.
Secondary entry sealing
We seal every other gap with possum proofing mesh and roof flashing. This stops the possum re-entering through a different hole and keeps rats, birds and snakes out of the roof space as well.
Follow-up inspection
We return after 7 to 10 nights to check the roof with the inspection camera. If there is no activity, we remove the door and seal the entry permanently. If a possum is still inside, we leave the door longer at no charge.
12-month warranty
Every installation comes with a 12-month workmanship warranty on the door and the proofing. If a possum gets back in through a sealed entry, we return and fix it at no cost to you.
Service overview
What One-Way Possum Door Installation Melbourne Involves
One-Way Possum Door Installation Melbourne is a wildlife-proofing service that fits a one-way exit door over the possum's entry point so it can leave but not re-enter.
We start with a full roof inspection using a roof ladder, torch and inspection camera to find every entry point, then mount the door on the primary access hole.
The door is a spring-loaded flap, usually steel or heavy-duty plastic, fixed to timber battens and sealed with silicone sealant so there are no gaps around the frame.
Melbourne possums cause most damage between March and October, when they look for warm, dry roof spaces in suburbs like Kew, Hawthorn and Balwyn. A possum in the roof is noisy at night, leaves droppings and urine that stain ceilings, and can chew through electrical cabling.
We fit a possum one-way door Melbourne homeowners can rely on, then return after 7 to 10 nights to remove the door and seal the entry with possum proofing mesh and roof flashing.
The service timeline
How We Install Your Possum Door
The process flexes to the condition, but these checkpoints keep decisions clear.
Roof inspection
We arrive with a roof ladder, torch and inspection camera and check the roof, eaves, wall cavities and chimney for entry points. We look for rub marks, droppings and possum hair. This takes 30 to 45 minutes on a typical Melbourne brick veneer home.
Entry point mapping
We identify the main access hole, usually a gap under a tile, a broken fascia or a hole in the eaves. We note any secondary entries so we can seal them at the same time. You get a written summary of what we found before we start work.
Door installation
We mount the one-way possum door over the main entry using timber battens and steel fixings, then seal the edges with silicone sealant. The flap opens outward only. Installation takes 45 to 90 minutes depending on roof pitch and access.
Proofing and sealing
While the door is working, we seal every other gap with possum proofing mesh and roof flashing. This stops the possum re-entering through a different hole and keeps rats, birds and snakes out too. We use steel mesh because possums chew through plastic.
Follow-up and removal
We return after 7 to 10 nights to check the roof with the inspection camera. If there is no activity, we remove the door and seal the entry permanently. If a possum is still inside, we leave the door another few nights at no extra charge.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
One-way possum door
A spring-loaded flap fitted over the entry point. It lets the possum push out but locks shut behind it, so the animal cannot re-enter the roof.
Inspection camera
We use a camera on a flexible pole to check wall cavities, ceiling spaces and roof voids for possums, droppings and chewed wiring without cutting holes.
Possum proofing mesh
Heavy-duty steel mesh fixed over entry points and gaps. Possums cannot chew through steel, unlike plastic mesh, which they tear apart within weeks.
Roof flashing
We use roof flashing to seal larger gaps around fascias, valleys and chimneys, then cover it with mesh so possums cannot push it open.
Cage trap and catch pole
For possums trapped in wall cavities or chimneys, we use a Havahart or Tomahawk cage trap and a catch pole to move the animal safely without injury.
Possum box
A timber possum box mounted in a nearby tree gives the evicted possum somewhere to go, which reduces the chance of it trying to get back into your roof.
Use cases
When to Book a One-Way Possum Door
These examples show how the service framework adapts rather than forcing every call through one repair.

Possum smell in a Camberwell ceiling
A possum had been in the ceiling of a Camberwell brick home for several months.
Urine had soaked into the plaster and insulation, causing a strong smell in the hallway and brown stains on the ceiling. → We fitted a one-way possum door, removed the soiled insulation and treated the ceiling space. The smell cleared within three days.
We sealed the entry with possum proofing mesh and fitted a possum box in the backyard.
Possum in a Brighton wall cavity
A possum had fallen into a wall cavity in a Brighton home and could not get out.
The homeowner heard scratching inside the wall and was worried the animal would die in place and cause a severe smell. → We located the possum with an inspection camera, used a catch pole and release cage to remove it safely, then fitted a one-way possum door at the external entry point. The wall cavity was sealed with steel mesh to stop it happening again.
Problems we solve
Possum Problems We Solve in Melbourne
Possums cause more damage in Melbourne roofs than most homeowners realise. Here are the problems we fix most often with a one-way possum door.
Possum noise at night keeping you awake
We fit a one-way possum door over the entry point so the possum leaves at night and cannot return. Most customers notice the noise stops within 1 to 3 nights of installation.
Possum smell and staining in the ceiling
We remove the possum with a one-way door, then treat the affected area and replace soiled insulation where needed. Sealing the entry with steel mesh stops new animals moving in.
Possum damage to roof and wiring
We seal every entry with possum proofing mesh and roof flashing, and fit a one-way door so the possum leaves without causing further damage. We check the roof for chewed cables during the inspection.
Possum in wall cavity or chimney
We use an inspection camera to locate the animal, then either fit a one-way door at the entry point or use a catch pole and release cage. We seal the cavity afterwards so it cannot happen again.
Pricing process
One-Way Possum Door Installation Cost
$280 - $650 depending on roof access, height and number of entry points
Roof height and pitch
A steep or double-storey roof takes longer to access safely and may need extra harness setup. This can add $80 to $150 to the job compared with a single-storey home.
Number of entry points
Most Melbourne roofs have 2 to 4 entry points. Each additional gap needs sealing with steel mesh and flashing, which adds time and materials. We quote per entry point so you can see the breakdown.
Possum location
A possum in the roof is straightforward. A possum in a wall cavity or chimney takes longer because we may need a catch pole and release cage, which adds to the cost.
Customer reviews
Reviews From Melbourne Customers
“We had a possum in the roof for months and the scratching at night was driving us mad. Frontline fitted a one-way possum door over the entry point and sealed two other gaps with steel mesh. The noise stopped after the second night. They came back a week later, checked with a camera and sealed the hole properly.”
“I called three companies and Frontline was the only one that explained how a one-way possum door works instead of just quoting a trap. They installed the door on a steep tile roof in about an hour, sealed the eaves and gave me a 12-month warranty. Worth every dollar.”
“A possum had been in our ceiling for weeks and the smell was terrible. Frontline removed the soiled insulation, fitted a one-way possum exit door and came back to check before sealing it. They also fitted a possum box in the backyard so the animal had somewhere to go. Very professional.”
Questions before we arrive
Frequently Asked Questions

How much does one-way possum door installation cost in Melbourne?
Most one-way possum door installations in Melbourne cost between $280 and $650, including the door, labour and sealing of secondary entry points. Price depends on roof height, pitch, how many entry points need sealing, and whether the possum is in the roof or a wall cavity. We give you a fixed quote before we start.
How does a one-way possum door work?
A one-way possum door is a spring-loaded flap fitted over the possum's entry hole. It opens outward when the possum pushes through on its way out to feed at night, then swings shut and locks. The possum cannot push it open from the outside, so it cannot get back into your roof.
Is a one-way possum door humane in Melbourne?
Yes. One-way doors are the humane option recommended under the Victoria Wildlife Act 1975. The possum leaves on its own, without injury or stress from trapping, and finds a new den nearby. We never use poison or lethal traps, and we can install a possum box so the animal has somewhere safe to move to.
Can I install a one-way possum door myself in Melbourne?
You can buy a door from Bunnings or Pestrol, but DIY installation often fails because the entry point is not sealed properly or a second hole is missed. Possums are strong and will push through gaps as small as 50mm.
We inspect the whole roof, fit the door correctly and seal every other entry, which is why our installations come with a 12-month warranty.
