parging in Woodstock

Up in Woodstock, old stone foundations are prone to moisture, so parging is a common fix when the original mortar starts flaking off. It's basically a thin coat of cement-based mix applied to exterior walls to seal and protect them. Locals usually do it themselves with a trowel, matching the texture to the old stonework, though hiring a mason costs more but looks more authentic. The trick is keeping the mix consistent and not letting it dry too fast in the summer heat.
