Stonework rarely needs repointing and renovating, and properties can go decades without needing any major maintenance to the exterior walls if they have been skilfully constructed. However, it’s inevitably that eventually the constant barrage of sun, wind, rain and frost can damage your stonework. And if you spot signs of disrepair, it’s important not to ignore them, or you could face more serious problems later on. If you notice any of these signs, you should consider ringing a stone specialist as soon as possible to diagnose the issue and find a remedy.

1. Cracked Walls and Foundations

It’s understandable that most people panic if a crack appears in the wall of the house, but not all of these faults are so sinister. Especially for new builds, this can occur naturally over the first few years as the property settles into its foundations. However a second opinion is wise, as large cracks and particularly ones caused by swelling, shrinking or subsistence can have serious implications.

2. Damp Walls

Natural stone is porous, but problems of damp shouldn’t occur if stonework has been professional installed and sealed. If walls are damp, there could be a variety of causes for this. Failing to properly seal walls leaves the walls open to absorb moisture, which can become trapped between the pointing. However pointing itself can also cause these issues, as hard cement prevents the natural release of moisture, instead leaving it vulnerable to decay. Other causes of damp include drainpipes running onto walls and flooding.

3. Crumbling stone

The issue of trapped moisture where stonework is unable to breathe can cause more serious problems to the overall condition of your walls, such as crumbling. If your window surrounds or stonework are in such as poor state that it is crumbling, it is far better to get a stone mason specialist to completely repair the damaged area than to patch it up. Simply trying to treat the symptoms of the problem rather than the root cause itself is unwise; you will probably only delay and even increase expenses when the issue has worsened in a few years.

4. Vandalism

A sad but very common cause of stonework problems can be vandalism, as graffiti or intentional damage to walls, statues and natural stone can leave it looking tired and an eyesore. Addressing these issues yourself can be a challenge, as each type of natural stone is best suited to different remedies. However a professional will be able to prescribe the right treatment to renovate your stonework, leaving it looking as good as new.

Maintaining the condition of exterior walls, patios and cladding is crucial for the kerb appeal and value of any property. It can also ensure that problems are addressed quickly, by someone with the necessary skills and expertise do the job properly. So please don't bury your hand in the sand, don’t ignore any of these signs if they do arise – call an expert to get peace of mind and the appropriate solution.
