According to The Dry Stone Walling Association:-
Dry stone walling is as much an art as a science, and this can occasionally give
rise to frustration and misunderstanding to those professionals not
fully acquainted with it. Seemingly inconsequential considerations can quite substantially affect the ease of construction and hence, price. A site visit and discussion prior to estimating will almost invariably be necessary for the waller.
The difference in standards between good and bad work are probably greater than in any other skill.This, combined with the need to recognise the inexperience of those professionals commissioning dry stone walling in judging the quality
of the product makes it essential to obtain the services of a qualified waller and with prestigious work, this is particularly so.To emphasise the point: work should last 100-150 years when carried out by a skilled waller, yet failure in 5 or less is frequent.
