Crafted energy-saving secondary glazing and insulation for period homes and listed properties.
Mitchell & Dickinson’s CosyGlazing is a unique secondary glazing system that is elegant and effective, with a strong return on investment.
Made of a modern, lightweight equivalent to glass, it’s fixed using magnetic strips so is easy to remove and virtually invisible. Choose a finish to complement your period or listed property.
Our high-quality draught-proofing and insulation solutions for underfloor, ceilings, sloping ceilings and lofts of period properties use naturally energy-efficient and sustainable sheep’s wool.
We also provide a full restoration service for your windows and doors, bringing them back to their original condition, able to both insulate your home and operate with ease.
With the government now announcing Britain will be virtually greenhouse gas free by 2050 and David Attenborough stating that we can all help achieve this goal by insulating our period properties, there is no better time to become part of the solution – and save money on your winter heating bills.
Based in Devon with surveying and operational teams in Bristol, Berkshire and Surrey, we help owners of listed and period properties to make their homes warmer throughout the South of England including the Cornwall, Devon, Somerset, Dorset, Gloucestershire, Bristol, Wiltshire, Berkshire, Surrey, Sussex, Oxfordshire, Warwickshire and Northamptonshire.
