Chimney Repairs & Leadwork
A chimney brings masonry, leadwork and roof coverings together at an exposed point. When one part fails, the leak can appear inside long before the cause is obvious outside.
A chimney brings masonry, leadwork and roof coverings together at an exposed point. When one part fails, the leak can appear inside long before the cause is obvious outside. DJW Roofing & Leadwork Ltd carries out chimney repairs and specialist leadwork in Ely, Littleport and across Cambridgeshire, Norfolk, Suffolk, Hertfordshire, Lincolnshire and North London. Danny’s 15 years’ roofing experience informs a whole-detail inspection rather than a guess based on one patch of damp. Free inspections and no-obligation quotes cover the advice you need before deciding on repointing, flaunching, flashings or more substantial repairs.
Assessing the chimney as a complete detail
Damp around a chimney breast can be caused by the roof junction, the stack itself or conditions inside the building. Flashings, mortar joints and the top of the stack need assessing together, since separate faults can occur at the same time. A visible crack is not always the only cause. We look at how rain reaches the chimney and how it should be shed back onto the roof. Where further specialist assessment is appropriate, that should be explained rather than giving an unsupported diagnosis.
Lead flashings and soakers
The flashing around the base of a chimney bridges the roof-to-masonry junction. Failed, lifted or split lead can allow driven rain under the covering. DJW removes old lead, chases the brick line to the correct depth and width, then forms the new lead with a straight edge and lead dresser. Soakers work between the courses of tiles or slates at the sides. The upper junction needs to direct runoff around the stack. Each part is detailed to suit the roof geometry rather than relying on a smear of sealant.
Repointing exposed chimney brickwork
Mortar joints can deteriorate under wind, rain and frost, leaving gaps that admit water into masonry. Repointing addresses the affected joints using an approach suitable for the condition and construction of the stack. It is important to distinguish a pointing issue from loose or damaged brickwork that needs a different repair. The inspection establishes which parts require attention and whether there is a concern about stability. On older buildings, compatible repair materials and any consent requirements also need considering before changes are made.
Flaunching and more substantial repairs
Flaunching is the shaped mortar around chimney pots at the top of the stack. It helps shed water and support the detail, but can crack or break down over time. Where renewal is needed, the form should direct water away rather than leave a surface that collects it. Chimney repairs can also involve rebuilding where the condition justifies that scope. These are decisions made after assessment, not default additions to every quote. We explain what is needed and why, including any access or further advice that the proposed work requires.
Roof junctions and safe next steps
Tiles, slates and valleys around the chimney can be affected by the same leak or exposure as the leadwork. Repairing the stack while leaving an adjacent roof defect may not resolve the problem. DJW considers the roof junction as part of the repair so the elements connect properly. Do not climb up to inspect a chimney yourself, especially if loose masonry or pots are suspected. Keep people away from falling-material risk and call for advice. DJW is fully insured, all work is guaranteed, and 24/7 emergency call-outs are available for urgent roofing concerns.

Chimney repairs
FAQs.
Does damp by a chimney always mean failed lead?
No. Leadwork, mortar joints, flaunching and other causes can produce similar signs. The chimney and adjoining roof need inspecting before deciding what to repair.
What is chimney flaunching?
It is the shaped mortar around chimney pots at the top of the stack. Cracking or deterioration can affect water shedding and needs checking as part of the chimney inspection.
Can you renew chimney flashings?
Yes. Old lead is removed, the masonry joint is chased properly and new lead is shaped by hand. Soakers and the surrounding roofing detail are considered alongside the visible flashing.
Do you carry out repointing and rebuilds?
Yes, where the chimney condition requires that work. We explain the appropriate scope after inspection, including any need for further assessment or consent.
Should I investigate loose chimney masonry myself?
No. Stay clear of areas where materials could fall and do not climb onto the roof. Call 07862 885143 to describe the situation and discuss safe next steps.
