We have a Grade II Listed 1740 Town House with Georgian facade with 9 front/side sash windows which rattled, leaked and once even let snow into our daughter’s bedroom. We had been looking for years for a suitable secondary glazing solution, which is sensitive to the Listing, easy on the eye and effective in terms of noise and heat loss reduction. Mitchell and Dickinson has been a superb choice! It uses a quality skilled team of surveyors, craftsmen and supported by best customer service. This is not a cheap option, however the payback period is good in terms of energy bills; and the quality of the work is superb. We have noticed immediately a huge difference in warmth in the house as well as a dampening of the external noise. We would recommend this company to anyone. The best customer experience we have had in years! Thank you.
