Drain Cleaning in Lisbon: Blocked Drains Cleared Fast

When a drain backs up in Lisbon — a kitchen sink that will not empty, a toilet that rises instead of flushing, a gully overflowing in the yard — the trouble is rarely the part you can see.

Ours is a drainage service that clears the blockage and then works out why it happened. We unblock sinks, toilets, showers and the mains that carry it all away, first with the tools that shift the everyday build-up of fat, wipes and scale, and then, where the run is stubborn or keeps coming back, with high-pressure water jetting and a CCTV camera that shows exactly what is going on inside the pipe. We have cleared drains across the city with our own team of 37 technicians since 1995, and we never hand the work to a subcontractor. We look at the job first and give you a clear price before we start, so the figure we agree is the figure on the invoice. For a blocked drain at any hour, call 211 304 186 or message us on WhatsApp on 911 791 640 — we are happy to sort it out in English.

The blocked drains we clear across Lisbon

A blocked drain rarely announces itself politely. It starts as a sink that empties a little slower, a gurgle from the shower, or a toilet that needs a second flush, and then one day nothing goes down at all. We deal with the full range of these problems every day, so whatever is blocking your drain, we have almost certainly cleared it before.

Inside the flat, the usual culprits are kitchen sinks clogged with grease and food waste, bathroom drains packed with hair and soap, and toilets blocked by wet wipes that never really break down. Further out, the trouble moves to the shared parts of the building: soil stacks that back up and affect several floors at once, external gullies filled with silt, and mains drains and inspection chambers choked with debris. Lisbon has a great many older buildings, and their narrow, twisting pipework blocks more easily than modern runs. Whether it is a single sink or a mains drain serving the whole block, the approach to drain cleaning is the same: find where the blockage sits, clear it at source, and confirm the pipe is running freely so it does not come straight back.

High-pressure jetting and CCTV drain surveys

We do not work blind. Shop-bought drain unblockers and a plunger might shift a light blockage, but they tend to push the real problem further down the pipe, where it settles and returns within days. For anything stubborn we use high-pressure water jetting, which scours grease, scale and root matter off the inside wall of the pipe and flushes it away completely, without damaging the pipework itself.

Before or after we jet the line, we run a CCTV camera through it. This lets us pinpoint exactly where the blockage sits, see what caused it, and prove the drain is clear once the job is done, so you can see the real condition of your pipes with your own eyes rather than taking our word for it. It is also what allows us to clear most blocked drains without breaking into walls or floors. Digging is a last resort here, not a first move: we only recommend structural work when there is genuinely no other way, and never before we have shown you why and quoted for it.

Clear quote first, and who is responsible for the drain

The complaint people have about this trade is nearly always the same: the bill. So we do it differently. We look at the blockage, explain what is causing it and give you a clear price before any drain cleaning begins. The figure we agree is the figure on the invoice, and if the job turns out to be simpler than expected, you are not paying for work that was not needed.

In a Lisbon apartment block there is an important distinction that decides who foots the bill. If the blockage is in the private branch serving your own flat, such as your toilet, shower gully or kitchen sink, it is usually down to you. If it sits in the shared soil stack or the building's mains drain, it is normally the responsibility of the condominium. Our CCTV survey shows exactly where the blockage is, and where it helps we can provide the footage and a written note to hand to the building manager. If you rent, that same recording makes the conversation with a landlord about responsibility far easier.

Same-day drain unblocking, day or night

Blocked drains have a habit of arriving at the worst possible moment: late at night, over the weekend, or on a public holiday, when the water has nowhere to go and the smell is starting to spread. We answer at any hour, right through the 365 days of the year, and get a technician out to you without a long wait so the problem is stopped before it turns into damp, mould and damage.

Our drain cleaning service covers the whole of Lisbon and Greater Lisbon, and because we run our own team we do not subcontract the work out. The person who takes your call belongs to the same firm as the technician who arrives to clear the drain, which is how we keep response times short. The technician sees the job before any work begins and agrees a clear price with you on the spot, and that agreed figure is the one on the invoice. While the technician is on the way, we will give you simple steps over the phone, such as not running that sink or flushing the affected toilet, to limit the mess until we get there. We work for private homes, condominiums, shops and restaurants, and a drain near me search in Lisbon should end with one call to us.

Frequently asked questions

Drain Cleaning in Lisbon: Blocked Drains Cleared Fast — common questions

How much does it cost to unblock a drain in Lisbon?+
It depends on where the blockage is and what is causing it, which is why we look first and give you a clear price before any work starts. A slow kitchen sink is a quick job; a mains drain that needs high-pressure jetting and a CCTV survey takes longer and costs more. The figure we agree is the figure on the invoice, with nothing added at the end. If the job turns out simpler than expected, you do not pay for work that was not needed.
Can you clear a blocked drain without breaking the walls?+
In most cases, yes. We run a CCTV camera down the pipe to find exactly where the blockage sits, then clear it with high-pressure water jetting, which flushes out grease, scale and debris without touching the walls or floor. Digging is a last resort, not a first move. We only ever recommend structural work when there is genuinely no other way, and never before we have shown you the footage and quoted for it.
Do you offer same-day drain cleaning near me in Lisbon?+
Yes. We cover the whole of Lisbon and Greater Lisbon and answer at any hour, right through the 365 days of the year, so a search for drain cleaning near me should end with one call to us. Because we run our own team of 37 technicians and do not subcontract, we can usually get a drain unblocking technician to you the same day, and often within a few hours for a drain that has stopped completely.
Who pays for a blocked drain in a Lisbon apartment block?+
It depends on where the blockage is. If it sits in the private branch serving your own flat, such as your toilet, shower gully or kitchen sink, it is usually down to you. If it is in the shared soil stack or the building's mains drain, it is normally the condominium's responsibility. Our CCTV survey shows exactly where the problem is, and we can hand you the footage and a short written note for the building manager or landlord.
Are shop-bought drain unblockers safe to use first?+
For a very light, occasional slow drain they can help, but we would not rely on them. Caustic shop-bought products often just push the real blockage further down the pipe, where it settles and returns within days, and repeated use can corrode older Lisbon pipework. They also do nothing for a blockage in the soil stack or mains drain. If the drain is fully blocked or keeps coming back, it is safer and usually cheaper in the end to have us clear it properly with high-pressure jetting and confirm it is clear with a CCTV survey.
