Flange Repair and Replacement for Toilet Troubles

A damaged toilet flange can cause more problems than you think. It’s a small part with a big job—keeping your toilet firmly in place and sealing the connection between your toilet and the drainpipe. When it’s broken, you might notice leaks around the base, foul smells coming from the floor, or even a wobbly toilet that shifts when you sit. It often occurs in homes and businesses in St. George. It often occurs in older homes near Kogarah and Sans Souci, where plumbing systems are outdated and flanges require repair or replacement for an extended period.

One of our clients in Hurstville recently called us about water pooling around their toilet. It turned out that the flange had cracked underneath the floor, causing a slow leak that damaged the subfloor. We repaired the flange, resealed everything properly, and restored their bathroom to top shape—all in the same day. No shortcuts, no mess left behind.

How Does a Toilet Flange Work?

Think of your toilet flange as the anchor that connects your toilet to the pipe below. It bolts to the floor and connects the toilet to the drainpipe using a wax ring or rubber gasket that forms a watertight seal. This seal prevents waste gases and water from leaking into your bathroom.

Manufacturers make most flanges from:

1. PVC (polyvinyl chloride): Lightweight, affordable, and rust-proof. Common in modern homes.

2. Cast iron: Durable and typically found in older buildings. It can corrode over time if not maintained.

3. Brass: Long-lasting and resistant to corrosion, but more expensive. Usually used in high-end installations or commercial properties.

If the flange becomes cracked, loose, or misaligned, the seal can break. That’s when leaks, smells, and toilet movement begin.

Signs You’ve Got a Flange Problem

Here’s what to watch out for:

1. Leaking water around the base of your toilet: If you notice puddles forming near the bathroom or dampness on the floor after flushing, it could indicate a broken flange seal or cracked flange.

2. Wobbling or rocking toilet: Your toilet should sit firmly on the floor. If it shifts even slightly when you sit or lean on it, the flange might be loose or broken.

3. Sewer smells in the bathroom: Persistent foul odours often mean that gases are escaping due to a broken or improperly sealed flange.

4. Visible damage like cracks or rust: If you’ve recently had your toilet lifted for any reason and you spot a cracked or rusted flange, it’s time for a replacement.

Pro-Tip: If your toilet is rocking, don’t just tighten the bolts—this can make the issue worse. You might crack the flange or the toilet itself. Have a plumber inspect it first.

Our Flange Repair and Replacement Process

We don’t do guesswork. We take great care to find the problem and fix it right the first time.

1. Inspection and Diagnosis: We start by examining the toilet base, subfloor, and flange. We might need to lift the toilet to get a better look. If there’s water damage, we assess its extent.

2. Repair or Reinforcement: If the flange isn’t completely broken, we might reinforce it using a repair ring or flange extender. This option works for minor cracks or slight misalignments.

3. Seal Replacement: In some cases, the flange is fine, but the wax ring or gasket is worn out. We replace the seal to restore the watertight connection.

4. Full Flange Replacement: If the flange is cracked, rusted, or detached from the floor, we’ll replace it entirely. This involves removing the old flange, prepping the area, and installing a new one securely.

5. Clean-up and Testing: Once we’re done, we clean the work area, reinstall the toilet, test it thoroughly, and double-check for any leaks or movement.

Pro-Tip: If your home has older cast-iron pipes, don’t delay repairs. Flange problems can quickly escalate into more significant pipe issues if left unchecked.
