Chimney Repairs in St Helens

Chimney stacks are positioned in one of the most exposed parts of a property, where they face rain, frost, wind and changing temperatures throughout the year.

Over time, these conditions can affect the mortar joints, brickwork, leadwork and materials around the top of the stack.

St Helens Roofers repairs chimneys on properties throughout the local area, from relatively minor pointing and flashing problems to more extensive deterioration affecting the stack itself.

Before recommending work, we assess the chimney together with the surrounding roof so we can establish where the problem is coming from and what needs attention.

Common Chimney Problems We Repair

Chimney Repointing in St Helens

Mortar joints between chimney bricks gradually deteriorate as they are exposed to the weather.

Cracking, crumbling or missing mortar can allow water to penetrate deeper into the masonry and may eventually affect the stability and condition of the stack.

Repointing involves removing loose or failed mortar from the affected joints before renewing them with a suitable mortar.

Where the bricks remain in satisfactory condition, this can restore the chimney without the need for more extensive rebuilding.

We assess the full stack before starting so that any damaged brickwork or other defects can be identified at the same time.

Chimney Repointing
Chimney Lead Flashing

Lead Flashing Around Chimneys

The point where a chimney passes through the roof is particularly vulnerable to water ingress.

Lead flashing is used to create a weather-resistant junction between the chimney stack and the surrounding tiles or slates.

If this leadwork splits, lifts, deteriorates or pulls away from the brickwork, rain can enter around the base of the stack.

Signs may include damp around a chimney breast, water staining in the loft or leaks appearing during periods of heavy rain.

Our roofers can assess the existing flashing and determine whether it can be repaired or whether affected sections need replacing.

Chimney Brickwork Repairs

Brickwork at roof level can deteriorate more quickly than masonry lower down the property because it is more exposed to weather.

Bricks may crack, become loose or begin to break down after repeated periods of moisture and frost.

Where deterioration affects only individual bricks, localised repairs may be sufficient.

If larger sections of the stack have become damaged, more extensive masonry work or a partial rebuild may be required.

We will explain the condition of the chimney and the options available before any major work is undertaken.

We noticed damp appearing in one of the bedrooms but couldn't work out where the water was coming from. They inspected the roof, showed us the damaged area and explained the repair before starting. No problems since and we've had plenty of rain to test it!

Had some guttering and roof repairs completed at our house in Prescot. Really straightforward from getting the quote through to having the work done. Would happily recommend them.

Frequently Asked Questions About Chimney Repairs in St Helens

Why is water coming in around my chimney?

Common causes include failed lead flashing, deteriorated pointing, cracked flaunching, damaged bricks or problems with the tiles or slates around the chimney. The area needs inspecting to determine the actual source.

How do I know if my chimney needs repointing?

Mortar that is cracked, crumbling, loose or missing between the bricks can indicate that repointing is required.

Can you repair chimney flashing?

Yes. We can inspect damaged lead flashing and repair or replace affected sections where appropriate.

Can chimney bricks be replaced individually?

Often, yes. Where damage is limited, individual deteriorated bricks can sometimes be replaced without rebuilding the complete stack.

What is chimney flaunching?

Flaunching is the mortar or cement finish around chimney pots at the top of the stack. It helps secure the pots and directs rainwater away from their bases.

Does a leaking chimney always need rebuilding?

No. Many chimney leaks are caused by pointing, flashing or flaunching problems that can be repaired without rebuilding the stack.

Do you repair chimney leaks as part of roof repairs?

Yes. Because chimney leaks often involve flashing or surrounding roofing materials, chimney work forms an important part of our wider roof repair service.
