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

Missing or damaged pointing

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.
