## Damp and timber problems in Londonderry

Derry has one of the most significant collections of historic building fabric in Northern Ireland, from the walled city centre outwards, alongside extensive Victorian and later housing.

Older city-centre buildings are typically solid-walled with no original damp proof course, and many have had decades of well-meaning but unhelpful modern repairs — cement render and impermeable paint that trap moisture in the wall.

Undoing that, and specifying treatment that lets the structure dry, is a large part of what we do here.

## What we see most here

- Rising damp in solid-walled city property
- Dry rot behind impermeable modern render
- Timber treatment in listed buildings
