Window sills may not appear to you as an extremely important part of your building exterior, but they do indeed play a crucial role in protecting your home from the elements. Their small incline allows water to run away from walls, protecting your property and keeping it dry.
As we know, in the UK it often likes to rain quite a bit, and a broken, uneven or cracked window sill can act as the first chink in your armour, allowing rainwater to leak into your property, instigating mould, stained walls and unpleasant smells.
Window sills are much more than just a decorative feature, and maintaining them will save you from ongoing problems and more expensive repair jobs in the future. They can be made from a range of materials, with sandstone and concrete window sills being common
Do You Need Our Stone Repair Service?
Over time, stone can become crumbly and brittle, and this is often because the stone is unable to ‘breathe’, this is when the moisture within the stone isn’t able to evaporate due to a coating on the stone, most commonly paint. When this isn’t possible, then your stone window sill will start to crack due to the expansion and contraction of moisture in variable weather conditions. Loose concrete or stone falling from a height is extremely dangerous, and concrete window sill repair should be carried out as soon as you notice any damage.


These complications can be fixed, of course, but will require a new stone either patched in or a complete replacement and Spectrum are proud to be able to offer you this expert service with our stonemasons, who have undergone specialist courses and training. Modern methods allow our repairs to impress each and every one of our clients consistently.
How To Repair Sandstone or Concrete Window Sills
Our stone window sill repair projects undergo the same systematic process that our team uses for every stone repair, and it is as follows:
- We first assess the site, running a full risk assessment and reporting back to our team with images and videos of the damage. This means that on the day of the repair, we are fully ready in advance, ensuring the most time-efficient and effective service.
- Depending on whether or not our IRATA (Industrial Rope Access Trade Association) trained abseilers are needed at the site, we will set up our rope access equipment for inspections of high-located stonework.
- Analyse the stone colour to ensure a seamless repair. This step is crucial in stone window sill repairs as it enables a flawless end finish.
- Our team will then mix and apply the bespoke stone compound with our lab-crafted colour-matching solutions unique to your stone, applying this to wherever the damage has occurred.
- Finally, we will sand down the excess stone mixture, giving your stone window sill a smooth finish, and leaving your building looking as good as new.
