5 Things to Consider when Repairing a Traditional Building
Published 15th March 2023
Let it breathe
Damp conditions in traditionally constructed building can be caused by later interventions, which may have been intended to seal out water, but in fact end up preventing the building from breathing. Look out for damp resistant paints and modern harling, which could trap water within the walls. Removing these may be the first step to a dryer wall!

Check your permissions
When repairing or making alterations to a listed building, it is vital to seek planning permission first; even if unlisted your building may be within a conservation area and accordingly have restrictions on what you can do without permission.

Think twice about Windows
Replacement of traditional wood sash and case windows with PVC may promise lower energy bills and less upkeep, however there are many interventions and upgrades which can be made to retain the embodied energy, craftmanship and appearance of the original windows whilst increasing their energy efficiency.

Master the Mix
Not all mortars are equal! When repointing or repairing traditional stone buildings it is important to find the correct mix to avoid damaging the stone and any remaining original mortar. Lime mortar is recommended for masonry repointing; see some answered FAQs here: https://www.scotlime.org/resources/faqs/
Climate Considerations
Although a building may have stood for hundreds of years, current changes in weather patterns and climate must be taken into account when carrying out repairs; for example, rainwater goods may need to be added or upsized.
