Mitchell & Dickinson

Mitchell & Dickinson offer elegant, bespoke and expertly crafted, full home insulation solutions with a strong return on investment for listed and period properties. Our products include our unique secondary glazing solution, CosyGlazing, high-quality draught proofing for windows and doors, and specialist sheep’s wool insulation for underfloors, sloping ceilings and lofts.  

Our solutions are tailor-made to your property and sympathetic to its original period features and aesthetic. We pride ourselves on our sustainable approach, using natural and energy-efficient materials which will stand the test of time. 

Quality is at the heart of everything we do. Our team of experienced craftspeople can install CosyGlazing, our advanced bespoke secondary glazing designed especially for your property; elegantly seal draughts with concealed brushes and hidden seals; make your lofts and floors cosy with sheep’s wool loft and underfloor insulation; stop the cold spots with sloping ceiling insulation; and restore windows and doors to their former glory.

We’ve completed projects in over 2,000 properties including for the National Trust, The Crown Estates, the Duchy of Cornwall, the Clovelly Estate, Exeter Cathedral, Wells Almshouses and many hundreds of privately owned listed and period homes, some of the finest heritage properties in the south of England.
