Termite Inspections Mortdale Heights

Mortdale Heights sits in a genuinely tight spot for termite risk, bounded by the Georges River to the west and Lime Kiln Bay to the south. That’s two bodies of water on two sides of the same small suburb, and the post-war brick and fibro homes built here after WWII sit at low elevation, which means the subsoil stays moist year-round from both the river and the bay. Moisture is the single biggest driver of termite activity, since it’s what termites are following when they move through soil in search of a way into timber.

The construction era matters too. Homes built in the years right after the war weren’t always fitted with ant capping (the metal cap between a brick pier and the timber bearer that blocks termites climbing straight up into the frame), and fibro construction from that period often has timber framing underneath that needs the same subfloor attention as any brick veneer home. Combine persistent subsoil moisture with a construction era that predates a lot of modern termite-prevention detailing, and Mortdale Heights is a suburb where I’d rather check every twelve months than assume a clean run will continue.

If your property backs directly onto the river or the bay, mention it when you book so I know to prioritise the subfloor and slab edge.

With water on two sides of the suburb, the subfloor is where I spend the most time on a Mortdale Heights inspection. I check for ant capping on the brick piers, and where it’s missing I look at whether a chemical barrier makes sense as the practical fix, since retrofitting ant capping means jacking the structure to slide a cap in, while a Termidor barrier can be trenched around the pier without disturbing anything. That trench method runs 300 by 300 mm trench dug around the pier and along the foundation walls, backfilled in alternating layers of soil and Termidor-treated soil to build up a protected zone.

I also check subfloor ventilation closely here, because low elevation next to the river and bay means airflow does more work in Mortdale Heights than it would in a suburb further from water. Where ventilation is poor, a subfloor fan is worth discussing. On the fibro homes, I’m checking timber framing condition as carefully as I would brick veneer bearers, since fibro doesn’t tell you anything about what’s underneath it. I use a moisture meter and thermal imaging camera through the subfloor to pick up damp patterns before they turn into visible timber damage.

I write the report on-site and hand it to you before I leave.

What does a termite inspection cost in Mortdale Heights?
A single-storey inspection is $280 and a double-storey inspection is $320. I price on the property itself, but that’s the typical range for homes in this area.

Why is termite risk higher in Mortdale Heights than in some nearby suburbs?
It comes down to water on two sides. The Georges River borders the suburb to the west and Lime Kiln Bay to the south, and the post-war homes here sit at low elevation, so subsoil moisture stays high year-round. Moisture is what draws termites toward a structure, so a suburb with water on two boundaries needs closer attention than one set back from the water.

How often should I get a Mortdale Heights property inspected?
Given the year-round subsoil moisture from the river and bay, I’d recommend every six to twelve months rather than stretching it out. If there’s a chemical or physical barrier on the property already, keeping those annual inspections up is also what keeps the warranty valid.
