Chimney repairs in Hampshire and Surrey

Inspect the chimney from its top to the roof junction

1. Locate the chimney symptom. Tell us where damp appears and whether mortar or brick fragments have fallen below the stack. We use those observations to guide an inspection of the chimney masonry and adjoining roof details.
2. Assess the masonry condition. The stack is examined for open joints, damaged brick faces and signs of movement. This separates pointing defects from deterioration that needs brick replacement or rebuilding before the weathering details are completed.
3. Check flashing and upper details. We inspect the junction with the roof, including the area behind the chimney. The top and existing cap are also assessed so the repair addresses the relevant rain-entry routes around the stack.
4. Specify the stack repair. Repointing, flashing renewal, rebuilding and cap work are described as distinct items. Access and any disturbance to surrounding slates or tiles are included in the proposed approach before chimney work begins.
5. Complete the adjoining weathering. After the agreed masonry and top details are addressed, the roof junction is checked around the stack. Disturbed coverings are reinstated so the repaired chimney meets the surrounding roof correctly.

Different chimney defects need different work

• Restore mortar joints: Repointing replaces deteriorated mortar where the brickwork is otherwise sound. The joint preparation and mortar choice need to suit the stack, rather than filling only the most visible gaps on its face.
• Renew chimney flashing: Failed metalwork at the base of the stack calls for a weathering repair. Our lead work addresses the connection with the masonry and the way rain passes onto the adjacent covering.
• Rebuild or address the top: Damaged stack sections need assessment for rebuilding, while cap defects require a suitable replacement detail. The proposed work reflects the masonry condition and the established use of the chimney flue.

How long chimney repairs takes

Chimney work depends on the height, position and extent of the masonry repair. Repointing a sound stack differs from rebuilding damaged sections, and the sequence also accounts for mortar work and completion of the surrounding flashing details.

What affects the price

• Stack height and access above the surrounding roof
• Extent and depth of deteriorated chimney mortar joints
• Quantity of damaged brickwork requiring replacement or rebuilding
• Flashing and back-gutter condition around the chimney base
• Work required to the chimney top and cap

Looking after it afterwards

Observe the stack from ground level for fresh debris or displaced flashing after severe weather. Indoor chimney stains need time to dry after the entry point is repaired. Report new wet marks rather than relying on old staining as evidence.
