Are DIY Plumbing Fixes Putting Your Home Insurance at Risk?

That dripping tap in the laundry. The toilet that keeps running. The slow drain in the shower. You have watched a few YouTube videos. You have got a toolbox somewhere. How hard can it be, right?

I get it. Plumbing calls cost money. And when you own a home, there is always something needing fixing. The idea of saving a few hundred bucks by doing it yourself is tempting.

But here is the thing. That DIY fix might cost you way more than you think. Not just in repairs if it goes wrong. But in your home insurance too.

I have seen too many homeowners learn this the hard way. A bloke in Grovedale tried to fix a leaking pipe under his sink. Used the wrong fittings. Went to Bunnings, grabbed what looked right. A month later, the fitting blew off while he was at work. Flooded his kitchen, ruined the floors, damaged the cupboards. Insurance came, looked at the cause, and said sorry. DIY work, not covered. He paid $15,000 out of his own pocket.

Let me walk you through what you actually risk when you pick up the tools. No scare tactics. Just the facts about why calling a licensed plumber Geelong homeowners trust is usually the smarter move.

What Your Insurance Policy Actually Says

“Laundry tap and sink installation by Hinch Plumbing in Geelong”

Here is something most people never read. The fine print in their home insurance policy.

Most policies have clauses about maintenance and workmanship. They say things like “you must maintain your home in good repair” and “we do not cover damage caused by faulty workmanship.”

Faulty workmanship includes DIY plumbing that is not up to standard. If you do the work yourself and it causes damage, the insurer can deny your claim. Every time.

The Insurance Council of Australia is pretty clear about this. If damage results from gradual deterioration, lack of maintenance, or faulty workmanship, it is generally not covered. That means you pay.

Some policies specifically exclude damage caused by “any deliberate, wilful, or illegal act.” In most states, doing plumbing work without a licence is illegal . So by doing it yourself, you are breaking the law. And then claiming for the damage it caused. Good luck with that.

The Common DIY Fails I See All the Time

Let me tell you about the stuff that goes wrong most often.

These are not rare mistakes. Plumbers see them all the time. The difference is, when a plumber does it, they have insurance. They fix it if something goes wrong. When you do it, you are on your own.

Water Damage Is Expensive

Let me put some numbers on this.

A small leak from a DIY pipe fitting might not seem like a big deal. But water finds its way. It runs along timbers. Soaks into insulation. Drips into wall cavities. By the time you notice, you have damage.

A typical water damage claim can run anywhere from $3,000 for a small fix to $30,000 or more if the damage is widespread . Ripping out wet plaster. Drying structures. Replacing flooring. Treating mould. It adds up fast.

If your insurance denies the claim, you pay every dollar.

That leaking tap you fixed yourself just became a very expensive mistake.

The Legal Side of Things

Here is something else to consider.

In Australia, plumbing work is regulated. Each state has its own rules, but generally, anyone doing plumbing work must be licensed.

In Victoria, where Geelong is, the Plumbing Regulations set out what work requires a licence. Anything that involves water supply, sanitation, drainage, or gas needs a licensed plumber. Doing it yourself is illegal.

If you do unlicensed work and something goes wrong, you are not just facing repair costs. You can be fined. Prosecuted. In serious cases, even jailed.

The Victorian Building Authority investigates complaints about unlicensed work. They take it seriously. And they do prosecute.

So that DIY fix is not just risking your insurance. It is risking your wallet in other ways too.

What About Minor Stuff?

Look, I am not saying you need a plumber to change a washer or unblock a toilet with a plunger. Some things are fine to handle yourself.

But here is a rough guide.

Safe to DIY:

Call a plumber:

If you are not sure, ask. A quick call to a local plumber Geelong residents recommend can save you a world of pain. Most will give advice over the phone for free.

Renovations Are a Different Story

If you are doing a new kitchen or bathroom renovation, do not DIY the plumbing.

This is where people really get into trouble. You are excited. You want to save money. You think, how hard can moving a sink be?

Very hard, as it turns out. Pipe sizing, venting, fall grades, trap placements. All of it matters. Get it wrong and you have smells, slow drains, and leaks behind walls you cannot see.

Plus, when you sell, the building inspection will pick up dodgy plumbing. Buyers will ask for money off. Or walk away.

Good plumbers Geelong locals trust have seen every renovation mistake possible. They know what works and what does not. Pay them to do it right the first time.

Gas Work Is Never DIY

This one is non-negotiable.

Gas work is licensed for a reason. Gas leaks kill people. Explosions destroy homes. Carbon monoxide poisoning is silent and deadly.

Never, ever DIY gas work. Not even something small. If you smell gas, get out and call a professional immediately.

In Victoria, gas fitting work must be done by a licensed gasfitter. Period. No exceptions.

What to Look for in a Good Plumber

If you are going to call a pro, call a good one. Here is what to look for.

FAQs

For very minor things like changing a washer, maybe. For anything involving pipes, water supply, drainage, or gas, no. It is illegal and risky. The savings are not worth the potential cost.

Probably not. Most policies exclude damage caused by faulty workmanship. If you did the work yourself and it fails, you pay.

Building inspectors find this stuff. They will note non-compliant work. Buyers will use it to negotiate money off or demand it be fixed before settlement. Best to do it right from the start.

Check the Victorian Building Authority website. They have a register of licensed practitioners. You can search by name or licence number.

Wrong fittings and loose connections. People grab what looks right from the hardware without understanding pressure ratings, material compatibility, or installation requirements. Then it leaks.

For major work, yes. New bathrooms, new homes, significant alterations usually need permits. Your plumber should handle this. Ask them about it.

Turn off the water at the mains if you can. Call a plumber immediately. Do not try to fix it yourself. Emergency call-out fees are worth it compared to flood damage.

Call-out fees range from $80 to $150. Hourly rates from $100 to $200. Emergency after-hours rates are higher. Always ask for a quote before work starts.

Unlikely. Plumbing standards exist for safety and performance. Without training and experience, it is hard to know all the requirements. Licensed plumbers spend years learning this stuff.

Ask neighbours. Look for local businesses with good reviews online. Ask if they are licensed and insured. Call a few and see who you feel comfortable with. A reliable plumber Geelong locals recommend will be happy to answer your questions.

Wrapping it up

Look, it’s right. You want to save money. You are handy. You have watched some videos. It feels like you should be able to handle it.

But here is the truth. Plumbing is more complicated than it looks. The standards exist for a reason. And your home insurance is not there to cover your mistakes.

A small DIY fix that goes wrong can cost you thousands. In damage. In denied claims. In fines. In stress.

A professional plumber costs a bit upfront but saves you money in the long run. They do it right. They stand behind their work. They have insurance if something goes wrong.

If you are in Geelong and need help with plumbing, call Hinch Plumbing. Have a chat. Get a quote. Know that the job is done right and your insurance is safe.

That peace of mind is worth more than any DIY saving.
