  • Guttering

    Adding guttering to your building is a great way to help reduce any water run-off down the sides of your building. This can help prevent any moisture ingress and any water pooling around your building, especially in particularly damp or exposed areas. You can also use your guttering to collect rainwater with a water butt, which is ideal if you have a lot of plants and need a lot of water during the dryer summer months.
