Professional Chimney Repointing In Slough & Windsor

This is usually caused by freeze-thaw cycles. Rainwater soaks into the porous mortar or bricks; when the temperature drops, that water freezes and expands, cracking the masonry. Over decades, this process causes the mortar to turn to dust and the brick faces to flake off. Professional repointing restores the seal and prevents further decay.

For standard repairs and repointing, you generally do not need planning permission. However, if your property is listed or located within a conservation area—such as near Datchet Village Green or Windsor Castle—there may be restrictions on the types of materials used. We can advise on matching existing materials to stay compliant with local guidelines.

If the damage is limited to the mortar joints, repointing is usually sufficient. However, if the stack is leaning, if the bricks are soft and crumbling throughout, or if the internal flue has collapsed, a rebuild may be necessary for safety. We provide a thorough inspection to determine the most cost-effective and safe route forward.

Flaunching is the mortar "crown" at the top of the chimney that secures the pots. It takes the worst of the weather. Because it is a large mass of mortar, it can shrink and crack over time due to temperature changes. Once it cracks, water enters the stack, which is why we often recommend replacing old, loose flaunching during a repointing job.

Yes. If your roof tiles or slates are in good condition but the lead flashing has perished or split, we can carefully remove the old lead, rake out the mortar joints, and install new Code 4 or Code 5 milled lead. This is a common repair that solves many "mystery" leaks in older properties across Uxbridge and Maidenhead.

Local knowledge matters for logistics and materials. Whether it is knowing the specific parking restrictions in Windsor or understanding the wind exposure levels near the river in Maidenhead, a local specialist like High class roofing provides a faster, more reliable service than a national firm.

We are very experienced with the logistics of the Thames Valley. We manage everything from skip placement permits to scaffolding licences through Slough, RBWM, or Hillingdon councils. We make sure our presence is as unobtrusive as possible for you and your neighbours.

As mortar ages, it loses its bond. High winds create uplift, and if the mortar bedding under your ridge tiles or the flaunching around your chimney pots is cracked, the wind can easily dislodge them. Regular maintenance and re-bedding prevent these components from becoming dangerous projectiles during severe weather.
