Delivery and Packaging
All products leaving our works are packed in a manner to ensure safe delivery to site.

Any joints that have suffered from frost damage should be carefully raked out and repointed. Any jointing that has cracked and it is suspected that this is because of movement, should only be repointed after the cause has been established.
The continuing effectiveness of these joints should be checked. If, due to excessive movement, the joint is no longer effective, the cause of this should be investigated and any remedial action undertaken. If the jointing material has ceased to be effective, it should be replaced.
The most likely cause of decay in stone is by water.
Bird fouling should be discouraged by the installation of anti-bird devices. The growth of algae and lichen can be limited where appropriate by the application of Biocides.
Creepers, such as Ivy, should be actively discouraged from growing as they will insert their roots deep into the masonry joints and cause long-term damage.
Rust staining and similar contamination caused by external ferrous items (e.g. signs and guard rails) should be investigated and the cause of the problem tackled.
Nameplates and Other Fitments
When nameplates etc are regularly cleaned, care must be taken to avoid staining the surrounding stone. The use of a tightly fitting masking plate is recommended.
Impact damage caused by external forces such as window cleaning equipment, vehicles etc, must be identified and rectified.
Graffiti is difficult to remove as it often penetrates the stone.
