Chimney stacks are the most maintenance-intensive part of any pitched roof. We repoint, reflash and rebuild stacks across the full coverage area. Covering Newton Aycliffe, Shildon, Heighington, Middridge and the surrounding area.
Chimney stacks are the most maintenance-intensive part of any pitched roof. We repoint, reflash and rebuild stacks across the full coverage area. Chimney repointing from £250. Lead flashing from £350. Full survey included.
Raking out and repointing deteriorated mortar joints on chimney stacks. Lime or cement mortar matched to the existing and the property age.
Full lead flashing replacement at chimney abutments using Code 4 and Code 5 lead sheet formed to BS 6915 specification.
Partial and full stack rebuilding where frost damage or settlement has caused structural deterioration beyond repointing.
Replacement of the mortar cap around chimney pots. Cracked flaunching is one of the most common sources of chimney water entry.
Supply and fit of replacement chimney pots and cowls. Half-round capping pots for unused flues to prevent water entry.
Mid-terrace and semi-detached party wall chimney work, ensuring the full shared stack is addressed rather than just one property's side.
Newton Aycliffe's housing stock is predominantly All post-war new town stock — 1950s through 1980s bungalows and semis with concrete interlocking tiles, many with flat-roofed extensions. Understanding the specific roof types and their failure modes is what separates a knowledgeable local roofer from a national firm that sends whoever's nearest.
Exposed position on the Durham plain with westerly weather; damp winters accelerate nail corrosion on original steel fixings. This directly affects how quickly specific roofing problems develop and which repair approaches last longest in local conditions.
Widespread nail sickness on 50–60 year old original fixings; flat roof failure on bungalow extensions; blocked valleys on properties with tree cover. We attend these jobs regularly across Newton Aycliffe and carry the most common materials on the vehicle to avoid return visits.
Industry-recognised quality and safety standards.
Written workmanship guarantee on all work.
Fixed quote before we start. No surprises.
We get on the roof before quoting. Always.
Chimney repointing from £250. Lead flashing from £350. Full survey included. No call-out fee.
“Nail sickness across the back slope of our bungalow. Diagnosed honestly — told us repair was viable rather than pushing for a re-roof. Saved us thousands.”
“Flat roof on our rear extension had been patched twice before. New GRP system fitted — wish we'd done it years ago.”
“Emergency call-out after storm damage. On site within the hour. Made safe that evening and permanently repaired the following morning.”

All chimney work in Newton Aycliffe starts with a scaffold-accessed inspection of the full stack — not a ground-level look with binoculars. From scaffold we inspect mortar joints, flaunching condition, lead flashing at all abutments, pot and terminal condition, and any visible cracking in the brickwork. Nail sickness is the dominant roofing issue across Newton Aycliffe — the town was built mainly in the 1950s and 1960s with original steel nail fixings now at end of life. An accurate diagnosis from scaffold level means the work quoted is the work that's actually needed rather than a conservative estimate covering unknowns we haven't looked at.
The decision between repointing and rebuilding a chimney stack in Newton Aycliffe depends on the structural integrity of the brickwork. Repointing is appropriate when the bricks are sound and only the mortar joints have eroded. Rebuilding is required where frost action has spalled the brick faces, where settlement or movement has cracked the stack, or where the mortar has eroded so deeply that the bricks themselves have shifted position. Predominantly post-war new town development from the 1940s–60s in Newton Aycliffe — the older the stack the more likely rebuilding is appropriate on the upper section even if the lower section is sound.
Lead at chimney abutments in Newton Aycliffe faces the specific stress of exposed plateau position with limited natural shelter creates significant wind exposure — mortar ridge bedding and nail fixings deteriorate faster here than in valley towns. Correctly installed lead with proper clips and expansion allowance handles this movement without cracking. The failures we see on Newton Aycliffe properties are almost always installation defects — lead fixed too rigidly, or installed in Code 3 when Code 4 or 5 is required. We use Code 4 for soakers and step flashings, Code 5 for cover flashings, and form all bays to BS 6915 lengths to accommodate thermal movement.
Yes — chimney work at height requires proper scaffold access. Any contractor offering to repoint a chimney from a ladder is working unsafely and without adequate insurance. We include scaffold in our chimney repair quotes; it's not an add-on.
Well-executed repointing in the correct mortar specification typically lasts 20–30 years. Using cement mortar that's too hard on an older brick chimney can cause the bricks themselves to crack before the mortar fails — we match mortar specification to the age and type of the stack.
Yes. An unused chimney is still open to the elements at the top. Without a capping pot, water enters the flue, saturates the internal brickwork, and appears as damp patches on interior walls. We fit half-round capping pots that prevent water entry while maintaining ventilation to avoid condensation within the flue.
Yes. We're registered with the National Federation of Roofing Contractors, which means we meet recognised industry standards for quality, safety and workmanship. All our work comes with a written 10-year workmanship guarantee.
Yes. All quotes are free, no-obligation and provided in writing. We get on the roof to measure and inspect before quoting — we don't estimate from the street. There's no call-out charge for the survey visit.
