What are common chimney problems?

Typical chimney problems include:

• Cracked or missing mortar
• Loose or spalling bricks
• Leaking lead flashing
• Damaged chimney pots or cowls
• Water ingress causing damp patches
• Leaning or unstable chimney stacks

Many of these issues are fixable if addressed promptly with the help of an experienced chimney repairer.

What are the signs of chimney damage?

Some chimney problems are visible from the ground, while others appear inside your home.

Common warning signs to look out for include:

• Damp patches or staining on chimney breasts
• Crumbling mortar or loose bricks
• White staining (efflorescence) on brickwork
• Rusting fireplace components
• Water dripping into the fireplace during heavy rain

If you notice any of these, hire a chimney specialist to take a look.

Can an old chimney be repaired?

Yes, most old chimneys can be repaired rather than replaced. Repair options often include:

• Repointing
• Replacing damaged bricks
• Renewing flashing
• Rebuilding the chimney stack above roof level

Complete removal or full rebuild is usually only needed if the structure is unsafe.

A chimney repair specialist can advise whether repair or replacement is the most cost-effective option.

Is it expensive to repair a chimney?

Chimney repairs don’t have to be expensive if problems are caught early.

Small jobs like repointing or replacing flashing are far cheaper than structural rebuilds.

However, ignoring issues such as loose mortar or leaks can lead to internal damp, roof damage, and higher repair bills later.

Is professional chimney repair worth it?

Yes – professional chimney repair is an important investment.

While a DIY fix may be tempting to save on costs, chimney work can be dangerous and complex.

Hire an experienced chimney repairer and they’ll:

• Accurately diagnose the problem using specialist CCTV cameras (if necessary)
