Who to Contact if Your Drains Are Blocked?

A blocked drain rarely waits for a convenient moment. The kitchen sink stops draining the night before guests arrive, the shower fills around your ankles, or the worst case — a manhole in the yard starts overflowing and you smell it before you see it. The first question almost everyone asks is the same: who do I actually contact, and how much is this going to cost me?

This guide answers that properly. We will cover the different types of drains, realistic price ranges in Pretoria, Centurion and Midrand, what makes one job cheap and another expensive, why a professional can open almost any blockage you cannot, and two things that quietly make blocked drains worse — repeated DIY attempts and pouring chemical drain cleaner down the pipe. By the end you will know exactly who to call and what a fair quote looks like.

The Short Answer: Who Should You Call First?

For anything beyond a simple, slow-draining basin, the right contact is a licensed plumber or a drain-cleaning specialist — not a handyman, and not another bottle of drain cleaner. A specialist has the tools to find the blockage, clear it without damaging the pipe, and tell you why it happened so it does not come straight back.

You should call a professional immediately if you notice any of the following:

• More than one drain is slow or blocked at the same time (a sign the main sewer line is affected).
• Water or sewage is rising up instead of going down.
• There is a gurgling sound in the toilet when you run a tap or the washing machine drains.
• A bad smell keeps returning even after cleaning.
• You have already tried a plunger or drain cleaner and it has not held.

If you are in Pretoria you can go straight to our Blocked Drains service. Lower down in this guide we also list the right contact for Centurion and Midrand.

The Different Types of Drains (and Why It Changes Who You Call)

“A blocked drain” can mean very different jobs. Knowing which type you have helps you describe the problem clearly and get an accurate quote the first time.

Internal waste drains

These carry water away from sinks, basins, baths, showers and the kitchen. Blockages here are usually caused by hair, soap scum, food waste and grease. They are often the cheapest and quickest to clear — if they are caught early.

Toilet and soil drains

These carry waste from toilets to the main sewer line. Blockages are commonly caused by too much paper, wet wipes (even the “flushable” ones), sanitary products or foreign objects. These need proper clearing rather than force, which can crack a pan or push the blockage deeper.

Main sewer / municipal connection drains

This is the main line running from your house to the municipal sewer or septic system. When this blocks, multiple fixtures back up at once and manholes can overflow. Tree-root intrusion, collapsed pipes and years of grease build-up are typical causes. This is specialist territory and often needs a drain machine or high-pressure jetting.

Stormwater and outside drains

These move rainwater away from the property. They block with leaves, sand, mud and debris, and are most noticeable after heavy Highveld summer storms when water pools instead of draining.

Blocked Drain Price Ranges in Pretoria, Centurion & Midrand

Prices vary by company and by how severe the blockage is, but the table below gives a realistic guide for the greater Pretoria, Centurion and Midrand area. Treat these as typical ranges for planning, not fixed quotes — always confirm with the plumber before work starts.

What Actually Changes the Price?

Two blocked drains on the same street can cost very different amounts. Here is what moves the number up or down:

• Severity and location of the blockage. A clog near the fixture is cheap. A blockage 12 metres down the main line is not.
• The cause. Soap and hair clear quickly. Tree roots, collapsed pipes or hardened grease need jetting or excavation.
• Access. An accessible cleanout or manhole keeps labour low. No access point means more time, and sometimes lifting tiles or digging.
• Equipment needed. A hand auger is included in most call-outs; a drain machine, high-pressure jetter or CCTV camera adds cost.
• Time of day. After-hours, weekend and public-holiday emergency call-outs carry a premium.
• Whether there is damage. If the camera finds a cracked or collapsed pipe, you are now paying for a repair, not just a clearing.

Why a Professional Can Open Almost Any Drain

It is not magic — it is the right tool matched to the right blockage. A homeowner usually has a plunger and a bottle of drain cleaner. A drain specialist arrives with equipment designed to reach and remove the actual obstruction:

• Drain machines (electric eels / augers) that physically reach deep into the line, break up the blockage and pull it out.
• High-pressure water jetters that scour the full diameter of the pipe, cutting through grease and fine roots and flushing the line clean.
• CCTV drain cameras that show exactly what is causing the blockage and where, so the fix targets the real problem instead of guessing.
• Drain rods and specialised attachments sized for different pipe types and bends.

Just as importantly, an experienced plumber knows how much force a pipe can take, which direction to work from, and when a blockage is actually a sign of a damaged pipe. That judgement is the difference between clearing a drain and accidentally cracking one.

Why You Should Stop Pouring Chemical Drain Cleaner Down the Drain

Caustic and acidic drain cleaners feel like the easy answer, but used repeatedly they often make things worse and more expensive. Here is why professionals warn against relying on them:

• They damage pipes over time. The heat and harsh chemistry can corrode metal pipes and soften or warp PVC and older fittings, eventually causing leaks.
• They rarely clear the real blockage. They may eat a small channel through soft gunk, so the drain seems to flow again — but the bulk of the clog, or a root or solid object, is still there and comes straight back.
• They turn a clog into a hazard. If the drain is fully blocked, the chemical sits in standing water. When a plumber then opens it, that caustic water can splash — a real injury risk.
• They are bad for your system and the environment. Repeated dosing harms septic-tank bacteria and pushes aggressive chemicals into the sewer and water system.
• They mask the cause. Recurring blockages usually mean grease build-up, roots or a pipe problem. Chemicals hide the symptom while the underlying issue keeps growing.

When DIY Fails: Why It’s Important to Call a Professional

There is nothing wrong with trying a plunger or clearing a hair trap yourself — for a minor, single-fixture clog that is sensible. The problem is what happens after a DIY attempt fails. People tend to escalate: more chemicals, more force, a wire coat hanger, a borrowed pressure washer. That is where damage and cost start to climb.

Call a professional once DIY has not worked, because:

• Repeated force can break things. Over-plunging or shoving rigid wire down a toilet can crack the pan or punch through an old pipe joint.
• A failed DIY usually means a deeper cause. If a plunger did not fix it, the blockage is often further down the line or caused by roots, grease or a structural fault — none of which a plunger reaches.
• You avoid throwing good money after bad. Several bottles of drain cleaner and a rented machine can cost more than a single proper call-out that actually solves it.
• A pro fixes the cause, not just today’s symptom. A camera inspection can show why it keeps blocking so you are not calling someone out every few months.

The honest rule of thumb: one quick DIY attempt is fine; a second and third are usually a false economy. If the first try did not hold, that is the moment to call.

Frequently Asked Questions

Who do I call for a blocked drain — a plumber or a drain specialist?

Either, as long as they have proper drain-clearing equipment. A licensed plumber handles most blocked drains; for severe main-line or recurring blockages, a team with a drain machine, high-pressure jetter and CCTV camera is ideal. In Pretoria you can use our Blocked Drains service.

How much does it cost to unblock a drain in Pretoria?

A simple sink or basin unblock typically runs about R450 to R1,200, while main sewer-line clearing or high-pressure jetting can range from roughly R1,200 to R5,500 depending on severity and access. Always confirm the call-out fee and quote before work starts.

Is it bad to use chemical drain cleaner?

Used occasionally on a minor clog it is usually fine, but relying on it repeatedly can corrode pipes, leave the real blockage in place, create a splash hazard for whoever opens the drain, and hide a bigger underlying problem. For anything stubborn or recurring, skip the chemicals and call a plumber.

Why does my drain keep blocking even after I clear it?

Recurring blockages usually point to a deeper cause — grease build-up, tree roots, a sagging section or a partially collapsed pipe. A CCTV drain camera inspection shows exactly what is happening so the problem can be fixed properly rather than cleared again and again.

Should I keep trying myself or call someone?

One quick attempt with a plunger or by clearing the hair trap is reasonable. If that does not work, calling a professional is the cheaper and safer route — repeated force and chemicals tend to cause damage and cost more than a single proper call-out.
