Buying a home is one of the biggest financial decisions most people make, yet the drains — some of the most expensive things to repair — are completely hidden from view. A standard building and pest inspection rarely puts a camera down the pipes. A pre-purchase CCTV drain inspection fills that gap, and this lesson explains why it is worth considering.
Why drains are a hidden risk
Underground pipes are out of sight and easy to overlook. A property can look immaculate above ground while a cracked or root-filled sewer waits beneath the garden. Because drain repairs can involve excavation and reinstatement, discovering a serious fault after settlement can be an unwelcome and costly surprise. An inspection turns an unknown into a known quantity before you commit.
What a pre-purchase inspection checks
A camera run before buying typically looks for:
- Tree root intrusion, especially where mature trees sit near the pipe route
- Cracks, fractures and collapsed sections
- Sags or bellies where water pools
- Blockages, heavy scale or grease build-up
- The general age, material and condition of the pipes
- Signs of past patch repairs or ongoing issues
The result is a clear picture of what you are actually buying, below the surface.
Older suburbs and mature trees
Many established Brisbane suburbs combine older pipe materials with large, mature street and garden trees. That is a classic recipe for root intrusion and joint problems. A charming character home may have equally characterful old drains. Knowing their condition before you buy lets you factor any work into your plans rather than being caught out later.
How findings help you
The information from an inspection can support your decision in several ways:
- Peace of mind — if the drains are sound, you can proceed with confidence.
- Negotiation — significant faults may be relevant to your discussions with the seller.
- Planning — if you buy, you already know what needs attention and can budget for it.
- Prioritisation — you learn what is urgent versus what can wait.
The cost of looking is small compared with the cost of discovering a collapsed sewer after you own it.
Fitting it into your process
Ideally, arrange the inspection during your due diligence period, alongside your building and pest checks, so you have the results before key deadlines. Keep the footage and report — they are useful evidence and a helpful baseline you can compare against in future. You may also want to read what a CCTV inspection reveals so you know what to expect from the results.
