Professional drain cleaning in London, Ontario
Get your drains flowing again
Slow drain, stubborn clog or water backing up? Donaldson provides professional drain cleaning in London and surrounding communities to safely clear blockages and get your plumbing flowing properly again.
Signs you need professional drain cleaning
A slow or clogged drain doesn’t always require a plumber. A plunger may clear a simple blockage, but stubborn or recurring clogs can be a sign that something farther inside the drain needs attention.
It may be time for professional drain cleaning if you notice:
If the problem won’t clear or keeps coming back, Donaldson’s licensed plumbers can assess what’s happening and determine the appropriate way to get things flowing again.

Professional drain cleaning for stubborn clogs
Not every clogged drain has the same cause or needs the same solution. Donaldson’s licensed plumbers assess the problem first, then use professional equipment to locate and clear the blockage safely.
We’ll explain what caused the blockage, tell you about anything else we notice and recommend only the work your plumbing actually needs. Drain cleaning is part of our plumbing services: if a clog has led to a leak or a damaged fixture, see plumbing repair, and if water is backing up into the basement, see sump pumps and flood prevention. Our local plumbers clear drains for homes in London and surrounding communities.
What to expect
From diagnosing the blockage to making sure your drain is flowing properly again, we’ll make the process straightforward and keep you informed along the way.
Step one
Schedule service
Call us now, fill out the form, text us or schedule online, whatever’s easiest. Tell us which drain is affected and what you’re noticing, and we’ll arrange a convenient time for one of our plumbers to visit your home.
Step two
Assess problem
Your plumber will inspect the affected drain and determine what may be causing the blockage. We’ll consider where the problem is happening, whether it has happened before and whether further inspection is needed.
Step three
Clear blockage
We’ll explain the recommended approach and provide upfront pricing before work begins. Once approved, we’ll use the appropriate professional equipment to clear the blockage and restore proper flow.
Step four
Test drain
After the blockage has been cleared, we’ll test the drain to make sure water is flowing properly. If we notice anything else that deserves attention, we’ll explain what we found before we leave.
Clogged drain causes
Most clogged drains develop as hair, grease, food waste, soap residue and other materials gradually build up inside the plumbing. The cause often depends on which drain is affected and what regularly goes down it.
A slow drain, standing water or recurring backup can be a sign that a blockage is developing. If the problem won’t clear or keeps coming back, it may be time to have the drain professionally assessed.

Simple ways to help prevent clogged drains
Not every clog can be prevented, but what goes down your drains can make a big difference. A few simple habits can help reduce buildup and keep your home’s drains flowing properly.
In the kitchen: keep grease & food out
Cooking grease and oils can collect inside drain lines as they cool, while food particles can add to the buildup. Dispose of grease separately, scrape dishes before washing them and keep as much food waste as possible out of the sink.
In the bathroom: catch hair before it goes down
Hair and soap residue are common contributors to slow bathroom drains. Use drain screens in sinks, showers and tubs to catch debris before it enters the plumbing, and clean the screens regularly.
At the toilet: watch what you flush
Stick to human waste and toilet paper. Wipes, paper towels, hygiene products and other household items can contribute to blockages, even when some products are marketed as flushable.
Pay attention to slow drains
A drain that gradually gets slower can be an early sign of buildup. If plunging doesn’t solve the problem or the same drain keeps slowing down, having it assessed before it becomes completely blocked can help prevent a more disruptive backup.
Skip the harsh chemical drain cleaners
Chemical drain cleaners aren’t always effective against stubborn or recurring blockages and can be hard on certain plumbing materials. If a clog won’t clear with simple homeowner-safe methods, professional drain cleaning is the better next step.

Drain cleaning FAQs
Have more questions? We’ve got the answers.
Donaldson provides drain cleaning for common household plumbing, including kitchen and bathroom sinks, toilets, showers and tubs, as well as dishwasher, laundry and basement drains. Not sure whether we can help with a particular drain? Call us now and tell us which drain is affected and what you’re noticing, or book drain cleaning online.
A recurring clog can be caused by ongoing buildup, material repeatedly entering the drain or a blockage that hasn’t been completely cleared. Grease in kitchen drains and hair and soap in bathroom drains are the usual causes. A camera inspection may be needed to find out why it keeps returning. If the pipe itself is damaged, see plumbing repair.
When appropriate, Donaldson can use a specialized drain camera to inspect accessible drain piping and investigate stubborn or recurring blockages. A camera isn’t necessary for every clog, so your plumber will recommend one when it can provide useful information, with upfront pricing before any work begins. Book a drain inspection.
Harsh chemical drain cleaners aren’t always effective on a stubborn or recurring clog and can be hard on certain plumbing materials. If plunging doesn’t clear the blockage, professional drain cleaning can. To avoid the next clog, keep grease out of the kitchen sink, use drain screens and flush only toilet paper. Book drain cleaning.
If several drains are slow or backing up at the same time, limit water use and call a plumber. Several affected drains can mean the problem is farther along the drainage system rather than in one fixture. We offer 24/7 emergency service. Call us now and we’ll work to get a technician to your home the same day, subject to availability. If water reaches the basement floor, see sump pumps and flood prevention.

The cost of drain cleaning depends on where the blockage is, what’s causing it, how accessible it is and the work required to clear it.
