Professional Chimney Repairs

Chimneys are exposed to rain, wind and temperature changes throughout the year.

Over time, mortar joints can deteriorate, bricks can become damaged and chimney flashing can fail.

A chimney problem can also become a roofing problem.

Defective pointing or flashing can allow water into the roof, while loose masonry, damaged pots or deteriorated mortar can create additional safety concerns.

We assess the condition of the chimney and surrounding roof before recommending the appropriate repair.

 


 

Chimney Repairs We Carry Out

Chimney Repointing

Deteriorated mortar joints can allow water into the chimney structure and surrounding masonry.

We can repair defective pointing where appropriate, using mortar suitable for the existing construction.

The extent of repointing required depends on the condition of the chimney.

 


 

Chimney Flashing Repairs

The junction between a chimney and roof is particularly vulnerable to water ingress.

We repair and renew chimney flashing including:Apron flashing

Step flashing

Cover flashing

Leadwork around chimney bases

Defective mortar associated with flashing

Localised flashing failures

Where suitable, rope access can provide access to high-level chimney and flashing repairs without traditional scaffolding.

 


 

Chimney Pot Repairs & Replacement

Chimney pots can become cracked, loose or damaged over time.

Depending on the condition, we can assess:

Cracked chimney pots

Loose pots

Damaged terminals

Defective mortar bedding

Associated leadwork

Where replacement is appropriate, we'll explain the proposed work.

 


 

Chimney Masonry Repairs

Brickwork and masonry can deteriorate through age, weather exposure and movement.

We can assess localised defects including:

Damaged bricks

Deteriorated mortar

Localised masonry damage

Cracking

Loose sections

Defective areas around chimney features

Where the damage is more extensive, we will explain what further work may be required.

 


 

Rope Access Chimney Repairs

High-level chimney repairs without traditional scaffolding where suitable

Chimneys can be difficult to access, particularly on tall Victorian and Edwardian properties.

NSG Roofers offer rope access for suitable chimney and roof repairs.

This can provide a practical alternative to traditional scaffolding for certain jobs.

Rope access may be suitable for:

Chimney repointing

Chimney flashing repairs

Leadwork

Localised masonry repairs

Chimney pot work

High-level inspections

Other difficult-to-access roof details

Using rope access where appropriate can potentially:

Reduce disruption around the property

Avoid the need for traditional scaffolding

Provide access to high-level areas

Make smaller repairs more practical

Rope access is not suitable for every property or every repair.

We assess the building, roof, chimney, access and proposed work before confirming the appropriate method.

Chimney Leaks & Water Ingress

Is water coming in around your chimney?

A leaking chimney doesn't necessarily mean the chimney itself is the only problem.

Water can enter through:

Failed lead flashing

Deteriorated mortar

Damaged masonry

Defective roof covering

Problems around the chimney base

Cracked or defective chimney details

Water can then travel through the roof structure before becoming visible inside the property.

Signs of a possible chimney-related leak include:

Damp patches around a chimney breast

Water staining on ceilings

Damp loft timbers

Water appearing after heavy rain

Leaking around the chimney area

Deteriorated flashing

Cracked or missing mortar

We assess the chimney and surrounding roof to establish the likely source.

 


 

Does Your Chimney Need Repointing?

Not every chimney requires complete repointing.

The condition of the mortar can vary considerably from one side of a chimney to another.

We assess:

Mortar deterioration

Open or missing joints

Crumbling mortar

Loose areas

Cracking

Brick condition

Flashing

Chimney pots

The surrounding roof

Where deterioration is localised, a localised repair may be appropriate.

Where more extensive repointing is required, we will explain the reason and proposed scope.

 


 

Chimney Repairs for Victorian & Edwardian Properties

North West London contains many properties with traditional brick chimneys and period roofing details.

Older chimneys often have features that need to be considered alongside the roof itself.

These can include:

Traditional brickwork

Lime or other traditional mortar

Lead flashing

Chimney pots

Multiple flues

Decorative brickwork

Roof-to-chimney junctions

Our approach is to repair the existing chimney appropriately wherever practical while respecting the character of the property.

 


 

Chimney Repairs Without Scaffolding

Could rope access save the disruption of scaffolding?

For suitable chimney repairs, rope access can sometimes remove the need for traditional scaffolding.

This can be particularly useful where:

The chimney is high

Access from the ground is restricted

The property is a terrace

The rear of the property is difficult to access

Only a localised repair is required

Traditional scaffolding would be disproportionate to the repair

Every property is different.

We'll assess the location and proposed repair before confirming whether rope access is suitable.

 


 

Common Chimney Problems We Repair

Contact NSG Roofers if you have noticed:

Crumbling chimney mortar

Missing or damaged pointing

Cracked bricks

Loose masonry

Damaged chimney pots

Loose chimney pots

Failed chimney flashing

Damaged leadwork

Water entering around the chimney

Damp around a chimney breast

Recurring leaks after previous repairs

Storm damage to chimney details

 


 

Why Chimney Problems Shouldn't Be Ignored

Small defects can become larger problems when exposed to repeated rain and frost.

Deteriorated mortar can allow water into masonry.

Defective flashing can allow water into the roof.

Loose masonry or chimney pots can also present a safety concern.

Getting problems assessed early can help determine whether a relatively localised repair is possible before deterioration becomes more extensive.
