Make your period property in Cornwallย warmer and more sustainable for the future with Mitchell & Dickinson

Crafted energy-saving secondary glazing and insulation for period homes and listed properties in Cornwall.

Mitchell & Dickinsonโ€™s CosyGlazing is a unique secondary glazing system that is elegant and effective.

Designed specifically for period homes and listed properties, it is the perfect solution when it comes to insulating Cornwall’s historic buildings.

Made of a modern, lightweight equivalent to glass, itโ€™s fixed using high-tech magnetic tape so it is easy to remove and virtually invisible. Choose a finish to complement your period or listed property.

We also provide high-qualityย draught proofingย for period properties such as sheepโ€™s wool insulation for under floors, lofts and sloping ceilings.

Quality is at the heart of everything we do. Our team of experienced craftspeople can install CosyGlazing secondary glazing; elegantly seal draughts with concealed brushes and hidden seals; make your lofts and floors cosy with sheepโ€™s wool loft and underfloor insulation; stop the cold spots with sloping ceiling insulation; and restore windows and doors to their former glory.

Our team of craftsmen based in the South West work for owners of listed and period properties across the South of England. Our innovative secondary glazing and insulation solutions are well suited to preserving Cornwall’s celebrated architecture, fine examples of which can be found in areas such as Redruth, Falmouth, St.Austell, Truro, Newquay, Penzance, Saltash, Bodmin, Helston, St Ives, as well as St Blazey, Liskeard, Launceston, Hayle, Torpoint, Bude, Wadebridge, Callington, Looe plus other areas in this magnificent county.
