Every Cornerstone roofing project carries a 10-year insurance-backed warranty, alongside the relevant material guarantee from the manufacturer.
Reliable, high-quality work before, during, and after the scaffold comes down.
Chimneys endure a significant amount of stress due to extreme weather conditions, frequent heating and cooling cycles, and condensation. Cornerstone Roofing offers a specialised chimney refurbishment service to ensure that your chimney, as well as your roof, remains both attractive and functional throughout the year.
Located typically above the roofline and completely exposed to the elements, chimneys face the full force of weather changes and temperature fluctuations. Our team of highly skilled and experienced roofers at Cornerstone Roofing is equipped to strengthen your chimney stack against these conditions with a range of refurbishment options.
Our extensive chimney refurbishment services include:
We understand that each chimney refurbishment project is unique, and so we tailor our services to meet the specific needs of each client.
Our services cater to a diverse range of residential and commercial properties within these areas, ensuring that every client has access to our specialised chimney repair and refurbishment services.
We carry out chimney flashing repairs (the lead detailing where the chimney meets the roof), chimney pot repairs and refurbishment, flue cleaning, and chimney lining work. Whether you’ve spotted damp around the chimney breast, smoke pulling poorly into the flue, or weather-damaged pots up top, we’ll inspect the chimney and recommend the work that’s actually needed.
Common signs include damp patches on the chimney breast inside the house, staining on upstairs ceilings near the chimney, lifted or damaged lead flashing where the chimney meets the roof, cracked or spalling brickwork, loose mortar joints, leaning or damaged chimney pots, and birds nesting in the flue. Any of these are worth booking an inspection for before they become a leak.
Yes. A failed chimney is one of the most common causes of leaks in pitched roofs. Damaged flashing, cracked mortar, or porous brickwork lets water track into the roof structure, where it can rot timbers, soak insulation and stain ceilings before you notice it from outside. The earlier a chimney issue is dealt with, the smaller the knock-on damage tends to be.
Chimney repair costs vary widely depending on what’s wrong. A localised lead flashing repair, replacing a cracked pot, relining a flue, and a full pot refurbishment are very different jobs, with very different access requirements. Rather than quote blind, we book a free visit, inspect the chimney and the area around it, and provide a written quote that reflects the actual work involved.
A pitched-roof chimney exposed to UK weather typically benefits from a visual inspection every couple of years, plus a check after any major storm. Catching small issues early (lifted flashing, perished mortar, a slipped pot) is consistently the cheapest way to keep a chimney watertight and structurally sound.
Chimney repair and refurbishment work is backed by a 10-year insurance-backed warranty on our workmanship, alongside the relevant manufacturer guarantees on materials such as flashing lead, pots and lining systems. The terms are set out in writing as part of your quote.
Yes. We carry out chimney repairs across Mid Sussex from our base in Scaynes Hill, covering Haywards Heath, Burgess Hill, Cuckfield, Hurstpierpoint, Hassocks, Lindfield and the surrounding villages. Damp around a chimney breast or visibly lifted lead flashing is worth getting inspected before the damage spreads into the roof structure.
