Most homeowners assume that if smoke goes up, the chimney is fine. But in reality, hidden chimney damage is a leading cause of house fires and carbon monoxide incidents in Ireland. Whether you are buying a house or noticing a strange smell, a Chimney Camera Inspection (CCTV Survey) is the only way to verify flue integrity. Read on to learn the 5 warning signs and the 2026 costs.
In the world of home maintenance, the chimney is often “out of sight, out of mind.” However, your flue is one of the hardest-working parts of your home’s infrastructure. It is subjected to extreme thermal shock, corrosive combustion byproducts, and the relentless Irish weather. Over time, even the best-built chimneys can develop structural flaws that are invisible to the naked eye. At The Soot Doctor, we use advanced German pan-and-tilt camera technology to navigate the full length of your flue. This isn’t just a “look up with a torch”, it’s a forensic diagnostic tool that identifies cracks, blockages, and nesting before they become emergencies.
One of the most immediate signs that your chimney requires a professional eye is “smoking back.” If you open the door of your stove or light a fire in an open hearth and smoke spills into the room instead of being pulled up the chimney, your flue integrity is compromised. While many people assume this is simply down to the wind or “cold air in the flue,” it often points to a physical obstruction.
A chimney camera inspection allows us to see if there is a partial collapse of the internal masonry or a dense bird nest that a brush simply can’t clear. In Ireland, Jackdaws are notorious for building deep, compacted nests that can act like a plug in your chimney. Without a camera, a sweep might clear the top layer, but the core of the nest remains, creating a dangerous back-draft of Carbon Monoxide.

If you are cleaning your hearth and notice small bits of red tile, sand, or mortar, your chimney is literally falling apart from the inside out. This process is known as “shaling.” Most traditional Irish chimneys are lined with clay or terracotta flues. Over decades, the acidic condensation from smoke eats away at the surface of these liners.
When we perform a CCTV survey, we often find that the smooth inner surface of the flue has become honeycombed or cracked. This is a massive safety risk because those cracks allow sparks and heat to reach the mid-feather walls (the walls between flues) or, worse, the timber joists of your home. If you see debris, the chimney camera inspection cost is a minor investment compared to the potential cost of a house fire.
If you have heard a “roaring” sound like a jet engine in your chimney, or seen sparks flying from the pot, you have had a chimney fire. Even if the fire department wasn’t called and the fire seemed to go out on its own, the damage is done. A chimney fire can reach temperatures exceeding 1,000°C. This intense heat causes clay liners to crack and stainless steel liners to warp or “buckle.”
You must never use a chimney again after a fire without a flue integrity check. A camera inspection is the only way to provide a chimney inspection report for your insurance company to prove the chimney is either safe to use or requires a specific repair. Lighting a second fire in a chimney that has been weakened by a previous fire is one of the most dangerous things a homeowner can do.
A chimney shouldn’t smell when it isn’t in use. If you notice a persistent acrid, smoky, or musty smell in your living room or upstairs bedrooms, it suggests that soot and creosote are absorbing moisture within the flue. This moisture then leaches through the masonry, carrying the smell with it.
Furthermore, if you see brown or yellow staining on the chimney breast in an upstairs bedroom, it is a sign that the flue is no longer airtight. The salts and tars from the soot are migrating through the brickwork. A camera survey can pinpoint exactly where the breach is occurring, allowing for a targeted repair rather than a blind, expensive guess at where the leak might be.
If you are buying a house, a chimney check is essential due diligence. Most standard structural surveys do not cover the internal state of the flues. We frequently see new homeowners move in, light their first “cosy” fire, and end up with a house full of smoke because the previous owners neglected the chimney for years.
Similarly, if you are upgrading from an open fire to a high-efficiency wood-burning stove, the old chimney must be inspected. Modern stoves put a different kind of pressure on a flue, and the smaller, hotter exhaust can cause old deposits of creosote to ignite if the flue hasn’t been properly vetted and cleaned. A professional chimney inspection report gives you the “green light” to enjoy your new home or appliance without fear.
We understand that homeowners need to budget for these services. In 2026, the chimney camera inspection cost in Ireland reflects the high level of technology and training required. For a standard residential property, you should expect to pay between €250 and €350 for a comprehensive service.
This price usually includes a professional power sweep, because you cannot inspect a chimney that is covered in soot, followed by the HD camera pass. If you require a formal, written chimney inspection report with video footage for insurance or a house sale, the cost is typically at the higher end of that scale. While it may seem like a significant outlay, it is far cheaper than the thousands of euro required for a full chimney rebuild or the devastating cost of a fire.

When The Soot Doctor arrives, we don’t just “have a look.” We follow a rigorous diagnostic process. We begin by sealing the fireplace to ensure no soot enters your home. After the sweep, we introduce the camera. Unlike basic “action cameras” that only look forward, our professional gear features a 360-degree rotating head.
This allows us to stop at every joint in the flue to check for gaps. We look for “spalling,” where the face of the brick is flaking, and we check for “bridging,” where soot has built up in a bend. This level of detail is what allows us to issue a reliable chimney inspection report. It’s about giving you the facts so you can make an informed decision about your home’s safety.

DISCLAIMER: INFORMATIONAL USE ONLY
A chimney camera inspection is a diagnostic tool designed to identify existing physical damage. While it is a vital part of home safety, it cannot predict future chimney fires if the appliance is used with incorrect fuel or if annual maintenance is neglected. Always consult with a certified technician for a tailored safety plan.
The entire process, including the set-up, the initial sweep, and the detailed camera pass, usually takes between 60 and 90 minutes. We take our time to ensure every inch of the flue is accounted for.
Not at all. We use industrial-grade HEPA vacuums and specialised hearth cloths to create a “sealed” environment. Our goal is to leave your home as clean, if not cleaner, than we found it.
A camera can see the face of a blockage, like a nest or a collapsed brick. However, the chimney must be swept first to remove loose soot so the camera can see the actual structure of the flue wall.
Yes. Our chimney inspection report is a professional document that details the condition of the flue, often used to support insurance claims after a fire or as part of the legal “contracts” during a house sale.
Yes. While stainless steel is durable, it can still suffer from “pitting” or corrosion if the wrong fuel is burned. It can also disconnect at the joints or buckle if there has been a chimney fire.
If we find issues, we don’t just leave you with bad news. We provide a list of recommended repairs, whether that is a specialised chemical creosote removal or a full relining of the chimney to make it safe again.
