St Andrews Church Hertford
The flint facing of this 19C listed church was coming away, which was dangerous and compromising the structural integrity of key parts of the church. The nave and south side-aisle roofs were also in poor condition.
Getting a match with the original unusual grey colour of the Victorian lime mortar was a consideration ; complicated by the existence of modern cement-based repairs. Lime mortars are usually very light and stand out against these. We used wood ash ( a traditional additive) to get the match.
Repairs were funded by the Heritage Lottery Fund ‘Listed Places of Worship’ scheme.
