Bird nest & Pest Removal
Bird Nest and Pest Removal from Chimneys in London, Hertfordshire & Essex
Birds love chimneys. The warmth rising up through the flue and the sheltered space at the top make them an ideal nesting spot, particularly for jackdaws, rooks, and starlings. The problem is that a nest inside your chimney is a blockage, and a blockage means gases can't escape properly. That's a fire risk and a carbon monoxide risk, and neither is something you want to ignore.
SweepSmart removes bird nests and pest debris from chimneys across London, Hertfordshire and Essex. We're members of the Guild of Master Sweeps, we follow all wildlife protection laws, and every removal includes a CCTV check and draught test to confirm the chimney is clear and safe before we leave


How Do You Know if There's a Bird Nest in Your Chimney?
You might not realise there's a nest in there until you start noticing the signs. The most common are twigs, feathers, or bird droppings falling into your stove or fireplace, chirping or tweeting sounds coming from the chimney, and increased bird activity around the chimney pot. If you're seeing any of these, it's worth getting the chimney checked.

Can You Remove a Bird Nest from a Chimney at Any Time?
No. Under the Wildlife and Countryside Act, it's an offence to destroy or remove an active nest during nesting season, which typically runs from March to August. We have to wait until the end of August, confirm the nest is empty, and then remove it. This isn't optional. It's the law, and we follow it.
If you're calling us during nesting season, we'll advise you on the situation and schedule the removal for when it's legally and safely possible. If you're concerned about fumes or blockages in the meantime, we can advise on interim measures to keep you safe.


What Happens During a Bird Nest Removal?
Once nesting season is over and we've confirmed the nest is no longer active, we remove the nesting material and debris from the flue using specialist chimney sweeping equipment. After the removal, we carry out a CCTV inspection with the Wöhler Vis400 and a smoke draught test to confirm the chimney is clear and drawing correctly. You'll know the flue is safe to use before we leave.

How Do You Stop Birds Nesting in a Chimney?
Here's the thing about jackdaws, rooks, and starlings: they return to the same nesting site year after year. Removing the nest solves the immediate problem, but without prevention, you'll likely be dealing with the same thing next spring.
We recommend having a bird guard fitted after removal. It keeps birds out of the flue permanently while still allowing the chimney to function normally. It's a one-off cost that saves you an annual headache. We supply and fit bird guards as part of the removal visit or as a standalone job.


Wasp and Bee Hive Removal from Chimneys
Chimneys aren't just popular with birds. Wasps and bees set up in chimney flues regularly. If you've got a hive, you'll likely need pest control to deal with the insects first. Once they've been treated, we can remove the hive from the chimney.
It's important not to leave an old hive in there, even once the insects are gone. Hives and the honey stored in them are combustible, which increases the risk of a chimney fire. The scent of an empty hive attracts more insects, creating a repeat problem. Hives can block the flue or fall further down into it, causing a deeper obstruction. And honey melts when the chimney heats up, bleeding through the brickwork and causing permanent staining on walls and ceilings.

Are Bird Nests in Chimneys a Health Risk?
Yes. Bird droppings that dry out inside a chimney can harbour a fungus that causes Histoplasmosis, a respiratory disease that can be serious if left unchecked. It's one of the less obvious reasons why a blocked chimney with nesting debris isn't just an inconvenience. It's a genuine health concern and another reason to get it cleared as soon as the law allows.

FAQs
Can you remove a bird nest from my chimney at any time of year?
No. Under the Wildlife and Countryside Act, it's an offence to destroy or remove an active nest during nesting season — typically March to August. We have to wait until the season ends, confirm the nest is empty, and then remove it. If you call us during nesting season, we'll advise on the situation and schedule the removal for when it's legally possible.
How do I know if there's a nest in my chimney?
Common signs include twigs, feathers, or bird droppings falling into your fireplace, chirping or tweeting sounds from the chimney, and increased bird activity around the chimney pot. If you're noticing any of these, there's a good chance something is nesting in there.
Will birds come back after the nest is removed?
Very likely, yes. Jackdaws, rooks, and starlings return to the same nesting site year after year. That's why we recommend fitting a bird guard after removal — it keeps birds out permanently while still allowing the chimney to function normally. It's a one-off cost that saves you an annual problem.
