I'm booked in for complete 40mm external wall insulation and rendering: the contractor says he will chop off the stone cill supports which extend 3 inches beneath the 100 year old stone window cills, as it will 'make for a neater job'. I'm worried that these 'supports' are not just old fashioned decorative features, but are actually necessary to keep the heavy stone cills in place, and therefore removing them is a bad idea!
Does anyone know the purpose of these objects, and should they stay put, or are they just cosmetic?
