Mitchell & Dickinson specialise in what they call integrated insulation for period and listed properties, treating insulation and ventilation as one system so that a house becomes warmer and drier without creating condensation or damp. Every project starts with a survey of heat loss, ventilation and moisture before a combination of measures is recommended. These include bespoke secondary glazing for sash, casement and stone mullion windows, vacuum glazing, draught-proofing, window and door restoration, heritage shutters, and natural-fibre loft and underfloor insulation, all compatible with listed buildings. The firm is Carbon Savvy certified and offers consultancy and service visits from regional teams.
Suitable for: improving comfort, acoustic performance and energy use in a listed house without altering or replacing original windows.
Services: bespoke secondary glazing; vacuum glazing; draught-proofing; window and door restoration; heritage shutters; loft, ceiling and underfloor insulation; ventilation advice; consultancy and service visits.
Location: Bideford, Devon; teams covering London, Berkshire, Bristol, Cambridgeshire, Devon and Cornwall.
