Standing water in your sink. A shower that drains slower each day. That unmistakable gurgling sound from your toilet. If you've experienced any of these, you know the frustration of clogged drains. For immediate help with a drain emergency, call (647) 554-4356—we're available 24/7.
After clearing over 50,000 drains across the Greater Toronto Area in my 28-year career, I've seen it all—from simple hair clogs to tree roots that split cast iron pipes in half. This guide covers everything Toronto homeowners need to know about keeping drains flowing freely, when to DIY, and when to call in the pros.
What Is Professional Drain Cleaning?
Professional drain cleaning goes far beyond what a plunger or store-bought chemical can accomplish. Licensed plumbers use specialized equipment designed to not just clear blockages, but to clean the interior walls of your pipes, removing buildup that causes future clogs.
The goal isn't just to restore flow today—it's to prevent the next clog from forming. That's why professional cleaning, while more expensive upfront, saves money over time by extending pipe life and preventing emergencies.
Professional Drain Cleaning Methods
Not all drain cleaning methods are equal. The right approach depends on your clog type, pipe material, and problem severity. Here's what professional plumbers actually use:
1. Drain Snaking (Cable Auger)
Cost: $99-$199
The most common method. A flexible metal cable with a cutting head is fed into the drain, breaking through or grabbing obstructions. Effective for hair clogs, soap buildup, and most household blockages.
Best for: Bathroom sinks, showers, tubs, minor kitchen clogs
Limitations: Doesn't clean pipe walls; clogs may recur faster
2. Hydro Jetting (High-Pressure Water)
Cost: $350-$600
Uses water pressure of 3,000-4,000 PSI to scour pipe interiors. Removes grease, scale, roots, and years of buildup. The most thorough cleaning method available.
Best for: Recurring clogs, grease buildup, main sewer lines, root intrusion
Limitations: Not safe for severely damaged pipes; requires camera inspection first
3. Camera Inspection (CCTV)
Cost: $150-$350
A small waterproof camera on a flexible cable inspects pipe interiors. Identifies clog location, pipe condition, root intrusion, cracks, and bellied (sagging) sections.
Best for: Diagnosing recurring problems, pre-purchase inspections, locating blockages
Often included: With hydro jetting; sometimes free with major repairs
4. Motorized Drum Auger
Cost: $150-$300
A powered version of the hand snake with more torque. Handles tougher clogs and can reach further into main sewer lines (up to 100+ feet).
Best for: Main line clogs, floor drains, deeper obstructions
Common use: When hand snaking fails
💡 Pro Tip from Mike
Always get a camera inspection before agreeing to expensive repairs. I've seen homeowners quoted $5,000+ for pipe replacement when $400 hydro jetting solved the problem. A good plumber will show you the camera footage and explain your options. Need honest diagnosis? Call (647) 554-4356.

8 Signs You Need Professional Drain Cleaning
Don't wait for a complete blockage. These warning signs indicate it's time to call a professional:
1. Slow Draining Water
Water pooling around your feet in the shower or taking minutes to drain from the sink signals buildup. This is the easiest stage to address—don't wait until it stops completely.
2. Recurring Clogs
If you're unclogging the same drain every few weeks, snaking is only treating the symptom. You likely have deeper buildup that requires hydro jetting or a camera inspection to identify the real issue.
3. Multiple Drains Backing Up
When multiple fixtures back up simultaneously—especially on the same floor—the problem is in your main line, not individual drains. This requires immediate professional attention.
4. Gurgling Sounds
Gurgling from drains or toilets indicates air trapped in the system, usually from partial blockages. It often precedes more serious backups.
5. Sewage or Rotten Egg Smell
Foul odors from drains suggest organic material decomposing in your pipes or a dried-out P-trap. Persistent smells may indicate sewer line issues requiring professional sewer repair.
6. Water Backing Up
Water appearing in other fixtures (sink fills when you flush toilet, basement drain backs up during laundry) indicates main line problems. Stop using water and call immediately: (647) 554-4356.
7. Fruit Flies or Drain Flies
Small flies near drains breed in organic buildup inside pipes. While they're more nuisance than emergency, they signal cleaning is overdue.
8. Water Pooling in Yard
Soggy areas or standing water near your sewer line path suggests a break or blockage causing sewage to seep into soil. This requires excavation or trenchless pipe repair.
What Causes Drain Clogs in Toronto Homes?
Based on our service data from 2024, here's what actually clogs Toronto drains:
Hair and Soap Buildup (34%)
The #1 culprit, especially in bathroom drains. Hair catches on pipe walls and trap bends, creating a mesh that catches everything else. Soap scum coats hair, hardening into dense mats.
Prevention: Install drain screens ($5-$15), clean weekly, avoid bar soap in showers.
Grease and Food Waste (28%)
Grease coats pipe walls, narrowing the opening. Food particles stick to grease, building layers over time. Hot water doesn't solve this—grease solidifies further down the pipe.
Prevention: Never pour grease down drains. Wipe pans with paper towels first. Use sink strainers.
Tree Root Intrusion (18%)
Toronto's mature trees—especially in High Park, Forest Hill, Rosedale, and The Beaches—send roots seeking moisture in sewer lines. Roots enter through joints and cracks, eventually filling pipes.
Prevention: Annual camera inspections for homes with trees within 30 feet of sewer lines. Consider pipe lining for older systems.
Mineral Scale (12%)
Toronto's hard water (especially in Etobicoke, North York, and Scarborough) deposits calcium and magite on pipe walls. Over decades, this restricts flow significantly.
Prevention: Water softeners, periodic hydro jetting, or water line upgrades.
Foreign Objects (8%)
Children's toys, feminine products, "flushable" wipes (they're not really flushable), and objects that slip down drains. These require snaking to extract.
Prevention: Childproof drain covers, proper waste disposal, never flush wipes.
DIY Drain Cleaning: What Works (and What Doesn't)
Some clogs you can handle yourself. Others require professional equipment. Here's how to know the difference:
DIY Methods That Actually Work
- Plunger: Effective for toilet clogs and minor sink blockages. Use a cup plunger for sinks, flange plunger for toilets.
- Zip-It tool ($5): A flexible plastic strip that hooks hair from bathroom drains. Use monthly as maintenance.
- Baking soda + vinegar: Pour 1/2 cup baking soda, then 1/2 cup vinegar, wait 30 minutes, flush with hot water. Works for slow drains, not complete blockages.
- Boiling water: Loosens grease buildup. Pour slowly to avoid thermal shock to pipes. Safe for metal pipes; be careful with PVC.
- Enzyme cleaners: Monthly use prevents buildup. Safe for all pipe types. Brands like Bio-Clean work well.
DIY Methods to AVOID
⚠️ Chemical Drain Cleaners Are Dangerous
Products like Drano, Liquid-Plumr, and store-brand chemical cleaners can:
• Damage pipes: Heat from chemical reactions warps PVC and corrodes metal
• Create toxic fumes: Especially when mixed with other products
• Burn skin and eyes: Dangerous splashback risk
• Harm plumbers: Residue creates hazards for future service
If chemicals don't clear the clog, you've now got a pipe full of corrosive liquid that a plumber must work around.
When to Call a Professional
- Plunging doesn't work after 3-4 attempts
- Multiple drains are affected
- Water backs up into other fixtures
- Sewage smell persists
- Same drain clogs repeatedly (monthly or more)
- You've used chemical cleaners (warn the plumber)
- Main sewer line appears affected

Toronto Neighborhoods With Common Drain Issues
Location matters for drain problems. Here's what we see most often across the GTA:
High Park, Forest Hill, Rosedale
Challenge: Mature trees and older clay pipes (pre-1970). Root intrusion is extremely common—we clear roots from 40% of service calls in these areas.
Recommendation: Annual camera inspection, consider pipe lining for prevention.
The Annex, Cabbagetown, Leslieville
Challenge: Victorian-era homes with cast iron pipes that corrode over time. Scale buildup reduces pipe diameter by 30-50% in many homes.
Recommendation: Hydro jetting every 2-3 years, eventual trenchless replacement.
Scarborough, North York, Etobicoke
Challenge: Post-war homes (1950s-70s) with aging pipes and hard water mineral buildup. Many have never had professional cleaning.
Recommendation: Professional cleaning every 18 months, consider water softener.
Mississauga, Brampton, Vaughan
Challenge: Newer subdivisions with longer sewer runs to municipal mains. Low-flow toilets can cause insufficient pressure to clear lines.
Recommendation: Avoid "flushable" wipes, use full-flush option for solid waste.
Downtown Toronto Condos
Challenge: Shared stacks mean your neighbor's problems can affect you. Grease buildup in high-rise kitchens is particularly common.
Recommendation: Report slow drains to building management immediately. Push for annual stack cleaning.
Drain Maintenance: Prevent Clogs Before They Start
The cheapest drain problem is the one that never happens. Follow this maintenance schedule to prevent 60-70% of clogs:
Weekly Maintenance (5 Minutes)
- Remove hair from bathroom drain screens
- Run hot water for 30 seconds after each use
- Wipe sink basins to remove soap film
Monthly Maintenance (15 Minutes)
- Use Zip-It tool to remove hair from shower drains
- Pour enzyme cleaner down all drains (follow product directions)
- Check under sinks for moisture or leaks
- Run water in rarely-used drains to maintain P-trap seal
Seasonal Maintenance
- Spring: Check exterior drains for debris after snow melt
- Summer: Monitor for root growth if you have mature trees
- Fall: Clear leaves from exterior drains weekly
- Winter: Insulate exposed pipes, know shut-off valve location
Professional Maintenance (Every 18-24 Months)
- Full drain cleaning by licensed plumber
- Camera inspection of main sewer line
- Address any developing issues before they become emergencies
💡 Pro Tip from Mike
Schedule professional cleaning in spring (March-April) before the busy season. You'll get faster service and often better pricing. Avoid Saturday morning calls—that's when emergencies spike and prices are highest. Water Pro offers weekday scheduling discounts—call (647) 554-4356.
Frequently Asked Questions
Most Toronto homes benefit from professional drain cleaning every 18-24 months. Homes with older pipes, mature trees nearby, or history of clogs should consider annual cleaning. High-usage households (4+ people) may need more frequent service.
Drain snaking uses a metal cable with cutting head to break through clogs ($99-$199). Hydro jetting uses high-pressure water (3,000-4,000 PSI) to thoroughly clean pipe walls ($350-$600). Snaking is for simple clogs; hydro jetting is for severe buildup, grease, or recurring problems.
Chemical drain cleaners like Drano can damage pipes, especially older cast iron or clay pipes common in Toronto homes built before 1970. They generate heat that can warp PVC and corrode metal. Use enzyme-based cleaners for maintenance, or call a professional for stubborn clogs.
In Toronto homes, the top clog causes are: hair and soap buildup (34%), grease and food waste (28%), tree root intrusion (18%), mineral scale from hard water (12%), and foreign objects (8%). Older neighborhoods with mature trees see more root problems.
You need cleaning if: one drain is slow, simple clogs clear temporarily, no sewage smells. You may need repair if: multiple drains backup simultaneously, gurgling sounds throughout house, sewage odors persist, or standing water in yard near sewer line. A camera inspection ($150-$350) can diagnose the issue.
While you can't eliminate clogs entirely, you can reduce them by 60-70% with proper maintenance: use drain screens to catch hair, never pour grease down drains, run hot water after each use, use enzyme cleaners monthly, and schedule professional cleaning every 18-24 months.
For after-hours drain emergencies: stop using water to prevent overflow, place towels around affected areas, and call a 24/7 plumber. Emergency rates are 50-100% higher ($150-$400), but waiting can cause water damage that costs thousands more. Water Pro offers 24/7 emergency service at (647) 554-4356.
Yes, Water Pro provides a 90-day guarantee on all drain cleaning services. If the same drain clogs within 90 days, we return to re-clean at no additional charge. For chronic issues, we offer maintenance plans with annual cleaning and priority scheduling.
The Bottom Line
Drain problems don't fix themselves—they only get worse. Whether you're dealing with a slow bathroom drain or a complete main line blockage, understanding your options helps you make smart decisions and avoid overpaying.
For minor clogs, start with DIY methods: plunger, Zip-It tool, or enzyme cleaners. For recurring problems, multiple affected drains, or signs of sewer issues, call a licensed plumber for professional diagnosis and treatment.
The best approach? Preventive maintenance. A $150 scheduled cleaning beats a $400 Saturday night emergency every time. Your pipes—and your wallet—will thank you.
