Unclogging, repair and replacement

Clogged toilet? How to clear it and when to call us

A clogged toilet can usually be cleared with the right steps, done in the right order, and we list them below. If the water is about to spill over or the plunger isn't doing the job, our plumbers unclog toilets day and night, with the price confirmed on the phone before anyone heads out.

  • The right tool, no scratched porcelain

    A toilet auger made for the bowl clears the blockage without marking the glaze, and anything stuck in there is pulled out rather than pushed further down.

  • Our own plumbers

    The plumber at your door is part of our team, never a subcontractor, and checks the main line if other drains are acting up too.

  • Price confirmed, work guaranteed

    The price is confirmed on the phone before we head out. You pay once the toilet is flowing again, and the work comes with a written guarantee on labour and parts.

Clogged toilet: what to do, in order

If the water rises in the bowl after you flush, stop the water supply first, then reach for the plunger. Done in this order, these steps prevent most of the mess.

  1. Don’t flush a second time. Another flush fills the bowl even higher and often sends it over the rim.
  2. Stop the water. Lift the tank lid and push the flapper down at the bottom, or close the small valve behind the toilet, near the wall.
  3. Protect the floor and wait. Lay down towels and let the water level drop on its own. A paper clog often softens a little while you wait.
  4. Use the right plunger. A flange plunger, whose rubber cup extends into a narrow sleeve, is made for toilets; the flat cup kind works better on sinks. There needs to be enough water in the bowl to cover the rubber.
  5. Seal, then push. Fit the flange snugly into the opening, push gently once to force the air out, then work it up and down firmly. Pull it off sharply at the end: the change in pressure often dislodges the clog.
  6. Test before turning the water back on. Once the level drops, pour a bucket of lukewarm water into the bowl to confirm everything drains, then reopen the supply.

Mistakes that make a clog worse

These can damage the porcelain or jam the blockage in tighter. Avoid:

  • chemical drain cleaners: they do little against a toilet clog, can harm the porcelain and the seals, and make the water dangerous for whoever has to work on it next;
  • a wire coat hanger: it scratches the glaze and can push an object even deeper into the bend of the bowl;
  • boiling water: the sudden heat can crack the porcelain;
  • forcing it when something has fallen in: a toy, a toothbrush or a phone has to be retrieved, not pushed through.

When the blockage is in the main line

A blocked toilet isn’t always a toilet problem. If water rises in the shower or the tub when you flush, if the basement floor drain lets water back up, if several fixtures gurgle at once or if a sewer smell fills the basement, the blockage is in the main line.

In that case the plunger won’t be enough, and running more water makes things worse. Hold off on the taps, the washing machine and the dishwasher, and read our advice on sewer backups. Blocked sinks, showers and floor drains are covered on our drain cleaning page.

When should you call a plumber?

Call if the plunger hasn’t changed anything, if something is stuck, if it’s the only toilet in the house or if other drains are reacting. Here is how our plumbers handle a blocked toilet:

  1. A call that pins down the problem. Someone on our team answers right away, asks the right questions and confirms the price before anyone heads out.
  2. An auger made for the bowl. The plumber uses a toilet auger, shaped to follow the bowl, so the glaze isn’t scratched.
  3. The line checked if needed. If the clog sits further down, the plumber moves on to the rest of the drain system.
  4. A watertight reset. When the toilet has to come off the floor, for example to recover an object, it always goes back down on a new wax ring to prevent leaks and odours. You pay once the toilet is flowing again.

How much does it cost to unclog a toilet?

The price depends on where the clog is, whether something has to be retrieved and the condition of the drain line. A clog in the trap of the bowl is often quick to clear. A toy or another object stuck inside can mean lifting the toilet off the floor to get it out, then setting it back with a new seal. If several fixtures back up at once, the problem is more likely in the main drain, and it becomes a different job. We ask a few questions on the phone and confirm the price before anyone comes out.

  • The price is confirmed before a plumber heads your way.
  • No obligation: you decide once you know the price.
  • Evenings, weekends and holidays included.
  • You pay once the toilet is clear and tested.

Repair or replace the toilet

Some toilets cause trouble even without a clog. A tank that runs nonstop wastes water day and night; a bowl that rocks on the floor eventually ruins the seal and the subfloor; cracked porcelain can start leaking at any time. Most of these problems can be repaired: the flush mechanism, the fill valve, the shut-off valve or the wax ring.

When the toilet is too far gone, when it drains poorly even with a clear line, or when you’re redoing the bathroom, replacing it becomes the better choice. We install new toilets, remove the old one and check the flange and the drain connection so the new one sits watertight. This work is booked at a time that suits you.

Common questions about clogged toilets

(438) 379-2352
Can I flush again to push the clog through?

No. If the water didn't go down after the first flush, a second one fills the bowl even higher and often makes it overflow. Wait for the level to drop on its own, then use the plunger.

Why does my toilet keep clogging?

A clog that keeps coming back often points to something stuck in the bowl, a partly blocked line further down, or a low-flow toilet that struggles to clear. A plumber can check both the bowl and the line to find the real cause.

Should I replace a toilet that clogs often?

Not necessarily. First make sure the blockage isn't in the drain line. If the bowl itself drains poorly, as some older models do, a new, well-designed toilet often solves the problem for good. We install new toilets and can help you choose the model.

The clog is gone but it still smells like sewer. Is that normal?

A lingering smell can come from a damaged wax ring at the base of the toilet or from a dried-out drain elsewhere in the house. If the smell is strong or there is water on the floor, have the toilet checked soon.

Is it an emergency at night?

If the water is overflowing, if it's the only toilet in the house or if other drains are reacting, yes. A plumber answers day and night and the price is confirmed on the phone before anyone comes out.

How do I keep the toilet from clogging again?

Flush nothing but toilet paper, because wipes, even the ones sold as flushable, don't break down the way paper does. Keep a small wastebasket in the bathroom for hygiene products, dental floss and cotton swabs, and put a lock on the lid if you have young children.
