"The team from Casa das Janelas were great to work with from start to finish; utterly professional and very nice too. They always came when they said they would, made excellent recommendations for solutions, completed the work to the timescale and cost they'd indicated, and went away leaving everything beautifully tidy! I will certainly be contacting them again about future work. Deirdre Tinney"
