Chimney Repairs & Leadwork

Expert Chimney Repairs You Can Trust

A chimney takes more weather than any other part of the roof. Frost breaks down the mortar joints, the cement crown on top cracks, and the lead flashing where the stack meets the tiles can lift or split. Any of these lets water run into the brickwork and down into the rooms below, often showing as damp patches on a chimney breast. TNR repairs chimneys on homes and commercial buildings across Hertfordshire, Hampshire and Surrey to stop that happening.

Leadwork is the other half of this service. Lead flashing seals the joints between the roof covering and walls, chimneys and dormers, and when it fails, leaks follow. We repair and replace flashing, repoint tired brickwork, rebuild crowns and flaunching, and fit new chimney pots, caps and cowls. Each job begins with a free inspection of the stack, so you know exactly what needs attention and why before agreeing to any work.

Why choose us

Why Choose TNR for Chimney and Lead Work

Free Stack Inspection

We check the brickwork, crown, pots and flashing before quoting, so the repair targets the real cause of the damp.

Masonry and Lead Together

Because we handle lead flashing as well as brickwork, the stack and its roof junction are repaired as part of the same job.

Pots, Caps and Cowls

Replacing a pot or fitting a cowl alongside other repairs saves paying for access to the chimney twice.

Insured Work at Height

Chimney repairs mean working high above the roof line, and our public liability insurance covers that work on your property.

Pricing

What Determines the Price of Chimney Work

Chimney repairs are quoted after a free inspection, with these factors making the most difference.

  • The height of the stack and the access or scaffolding needed to reach it safely.
  • How much brickwork needs repointing or rebuilding.
  • Whether the crown or flaunching needs patching or full replacement.
  • The amount of lead flashing to be repaired or renewed.
  • Any new pots, caps or cowls you choose to add.

The work

Our Chimney Repair Process

The main stages of the job, from the first inspection to the final check.

  1. Chimney Inspection

    We examine the stack from top to bottom, checking mortar joints, the crown, the pots and the lead flashing at the roof line.

  2. Recommendations and Quote

    You get a clear account of what has failed, what we suggest repairing now and a free, no-obligation quote.

  3. Masonry and Lead Repairs

    Joints are raked out and repointed, crowns and flaunching are rebuilt, and new lead is dressed into place so it sheds water away from the stack.

  4. Final Chimney Check

    After making sure the surrounding tiles are sound and clearing away old mortar and lead, we review the completed work with you and confirm everything has been done as agreed.

FAQs

Frequently Asked Questions

What chimney repairs do you offer in Hertfordshire?

We repoint brickwork, rebuild crowns and flaunching, repair or replace lead flashing, and fit new chimney pots, caps and cowls for properties across Hertfordshire, Hampshire and Surrey.

Why is chimney lead work important?

Lead flashing seals the gap between the chimney and the roof covering. When it lifts or cracks, rain runs straight into the roof space, so keeping it intact prevents damp and timber decay.

How do I know if my chimney needs repairing?

Look for crumbling mortar, a leaning or cracked pot, plants growing from the stack or damp patches on the chimney breast inside. A free inspection will confirm the cause.

Can chimney repairs prevent roof leaks?

Often they can. Many leaks blamed on the roof actually start at the chimney, through failed flashing or porous brickwork, so repairing the stack stops them at source.

Are your chimney repairs and lead work fully insured?

All the chimney and leadwork we carry out is covered by our public liability insurance.
