The Hidden Danger in Older Homes and How to Get Rid of It Safely

Inside the article

Old houses have charm. High ceilings. Original fireplaces. Thick walls and timber floors.

But under the paint and plaster, something else might be lurking. Something you won’t spot on a walk-through. Something that could harm your health for years.

It’s called asbestos.

If your home was built or renovated before the year 2000, this dangerous material could still be there, quietly sitting in ceilings, floors, cupboards and lofts.

And once it’s disturbed, it becomes a serious problem.

Why Asbestos Is So Dangerous

Asbestos was once used in everything from ceiling coatings to boiler insulation. It was strong, fireproof, and cheap. That’s why it was used for decades.

The problem starts when it’s damaged or disturbed.

Asbestos materials break into fine dust. You breathe it in. It sticks in your lungs. Years later, it can cause deadly illness—often before you even realise what’s happening.

These illnesses include:

Mesothelioma (a rare and aggressive cancer)
Lung cancer
Asbestosis (scarring of the lungs)
Pleural thickening (which makes breathing harder)

There’s no cure. And no warning signs at the time of exposure.

Which is why knowing where asbestos is—and dealing with it properly—is so important.

Where Asbestos Might Be Hiding

You can’t spot asbestos just by looking. It’s often mixed with other materials or hidden behind walls and under floors.

In older homes, it might be found in:

Ceiling tiles and Artex coatings
Floor tiles and tile adhesives
Pipe lagging and boiler insulation
Inside partition walls
Loft insulation
Water tanks
Old fuse boxes

You might walk past it every day and never know.

Until the builder arrives.
Until you decide to remove a ceiling.
Until it’s too late.

How to Check If Your Home Has Asbestos

You need a qualified asbestos surveyor.

A qualified surveyor will inspect your property and collect samples from anywhere asbestos might be present. These are sent to a lab for analysis. Once the results are in, you’ll get a clear report showing where the danger is and what to do next.

There are two types of survey:

Management Survey

Used when the property is being used normally—no major building work planned. This survey looks for asbestos in accessible places.

Refurbishment and Demolition Survey

Used when renovation, extension, or demolition is planned. This one is more intrusive and checks hidden areas where asbestos might be disturbed during building work.

If you’re planning any kind of structural work, the second survey is legally required.

What Happens If You Find It?

That depends.

If the asbestos is in good condition and in a spot that won’t be disturbed, it might be left in place and monitored. It’s still a risk—but a controlled one.

If the material is damaged, flaking, or in an area you want to renovate, it needs to be removed.

And that’s not a job for a general builder.
It’s not a DIY weekend project.
You need a licensed asbestos removal team.

They’ll seal off the area, wear protective gear, remove the materials safely, and dispose of everything according to strict rules.

Done properly, it’s safe.
Done badly, and the whole house could be contaminated.

What You Must Never Do

Never drill, cut or sand suspicious materials.
Never try to remove asbestos yourself.
Never ignore it and hope for the best.

Disturbing asbestos without knowing what you’re dealing with is the most dangerous part. Once the dust is in the air, it can settle into soft furnishings, clothing, and air ducts. It doesn’t go away on its own.

How Much Will It Cost?

A survey usually costs between £250 and £450 for a standard home, depending on the type and size of the property.

If removal is needed, the cost varies based on location, amount, and access. Some jobs cost a few hundred. Others, especially if a whole ceiling or boiler system is involved, may run into the thousands.

But it’s still cheaper than a contaminated home—or a serious illness later on.
