What Is the Best Drain Cleaning Service in London, Ontario?

The best drain cleaning service in London, Ontario is a licensed, experienced plumbing company that uses advanced tools — such as hydro jetting and camera inspections — to remove blockages at the source, not just temporarily clear them.

Clogged Drain in London? Don’t Wait Until It Gets Worse

A slow drain is rarely just a minor inconvenience. In most cases, it’s an early warning sign that something is building up inside your plumbing system. Whether it’s grease in a kitchen line, hair and soap residue in a bathroom drain, or tree roots invading an underground pipe, these issues worsen over time.

Homeowners and business owners across London, Ontario often wait until water backs up or drains stop working entirely before calling for help. By that point, the problem is usually more complex and more expensive to fix. At BEST Plumbing and Drainage Contractors, we focus on identifying and resolving the root cause early — before a clogged drain becomes a plumbing emergency.

Why Professional Drain Cleaning in London Ontario Is Essential

Many property owners reach for store-bought drain cleaners or a plunger when a clog appears. While these methods may provide temporary relief, they rarely eliminate the underlying buildup inside the pipes. In some cases, chemical cleaners can actually damage plumbing materials, especially in the older homes found throughout many of London’s established neighbourhoods.

Professional drain cleaning takes a completely different approach. Instead of simply pushing a blockage further down the line, trained technicians remove buildup from the interior walls of the pipe. This restores proper flow and significantly reduces the likelihood of future clogs. In a city like London, where many properties have aging infrastructure and mature trees, deeper cleaning methods are often necessary to maintain a healthy plumbing system.

What Causes Drain Problems in London Homes and Businesses?

Drain issues develop over time due to everyday use combined with environmental factors specific to Southwestern Ontario. The most common causes our drain cleaning team encounters in London include:

• Kitchen drains: Grease, fats, and food particles that gradually accumulate and harden along pipe walls
• Bathroom drains: Hair and soap residue that restricts water flow and creates stubborn clogs
• Sewer lines: Tree root intrusion — one of the most common causes of blocked drains in older London neighbourhoods
• Commercial properties: High usage levels that place constant strain on drainage systems, making preventative drain cleaning essential

Signs You Need Drain Cleaning in London Ontario

Drain problems almost always provide warning signs before they become emergencies. Recognizing these early can save you from costly damage. Call our London drain cleaning team if you notice:

• Slow-draining sinks, tubs, showers, or floor drains
• Recurring clogs that keep returning despite repeated clearing
• Gurgling or bubbling sounds from drains or toilets
• Foul or sewage-like odours coming from drains
• Water backing up into multiple fixtures at once — a strong sign of a main sewer line blockage

Our Drain Cleaning Services in London, Ontario

BEST Plumbing and Drainage Contractors offers a complete range of drain cleaning solutions tailored to both residential and commercial properties in London and the surrounding area.

Drain Snaking

For minor blockages, professional drain snaking quickly restores flow to sinks, tubs, and floor drains. It’s a fast, non-invasive solution for straightforward clogs.

Hydro Jetting

For severe or recurring drain problems, hydro jetting is the most effective drain cleaning method available. High-pressure water scours the full interior of the pipe, removing years of grease, soap buildup, debris, and even tree roots. This is the drain cleaning solution preferred by professionals because it delivers a true, lasting clean.

Camera Drain Inspections

Using advanced drain camera technology, our team pinpoints the exact cause and location of any blockage. This eliminates guesswork, ensures the correct drain cleaning method is applied, and saves you money by avoiding unnecessary work.

Main Sewer Line Cleaning

When blockages affect the main sewer line, the entire property is impacted. Our drain cleaning team uses professional-grade equipment to clear main lines quickly and prevent backups from escalating into serious property damage.

High-Pressure Sewer Flushing

For lines with heavy grease buildup, sediment, or stubborn root intrusions, our high-pressure sewer flushing service delivers a deep, thorough clean. We use three different pressure flushing systems to handle pipes ranging from 1.5” to 30” in diameter — a 1,600 PSI system for smaller residential lines, a 3,000 PSI system for mid-range lines, and a powerful truck-mounted system for larger commercial and municipal pipes. This method is highly effective where standard snaking or jetting alone isn’t enough.

Pipeline Video Inspection

Our pipeline video inspection service provides a thorough, non-invasive look inside your sewer lines. Using high-resolution cameras capable of travelling hundreds of metres through pipes, our technicians can identify blockages, root intrusions, misaligned joints, and collapsed sections with precision. This diagnostic tool eliminates guesswork, reduces repair time and cost, and ensures the right solution is applied — the first time. It’s particularly valuable in London’s older neighbourhoods where aging infrastructure is common.

Sewer Repair and Replacement

When drain cleaning isn’t enough, our team handles full sewer repair and replacement. Damaged, collapsed, or deteriorated sewer lines require more than a cleaning — they require excavation and expert installation of new pipe. Whether you’re dealing with a cracked lateral, a collapsed section, or a failed older line, BEST Plumbing and Drainage Contractors provides prompt, professional sewer repair and replacement for residential and commercial properties across London and Southwestern Ontario. We resolve the problem properly so it doesn’t come back.
