"We’d had black mould forming on our bay window for years and had almost given up trying to clean it off. Nothing we tried ever worked. Then we came across Wojtek at aPlastering. He did an outstanding job. He helped us choose the best insulation product for our situation and explained everything in detail, including how ventilation works and how to stop the problem coming back."

We’re really happy with the result and would definitely recommend them."
