Mr S
We are thrilled with our new insulating windows

We have just returned from Italy and are thrilled with our new insulating windows. They are very discreet and smart and will clearly provide excellent insulation. The front door also is quite transformed and fits much more snugly into its frame.

Professionalism and high standard of workmanship

I would like to commend the workers, who installed my internal glazing and refurbished my sash windows, for their professionalism and high standard of workmanship. They worked hard and were friendly and polite throughout their stay. All contact with the company was received in a friendly and professional manner. I would highly recommend this company to other potential customers.

I have been impressed by every aspect of the service - initial discussion, quotation, survey, installation

All the personnel I dealt with were courteous, patient and utterly professional. The product is barely visible in situ, which is exactly what I wanted, and I am already benefitting from a lack of draughts. I now feel much more confident about facing the winter here.

Highly recommended if you are in the market for secondary glazing.

The product itself is a conservationist's dream - you would hardly notice it once installed. Very impressive in that sense and truly meets the standard of "minimalist intervention". In fact, we sought and achieved listed building consent even though there is a strong argument that the product is "temporary" in nature. It was nice to get the Local Authority's formal approval though.

Mitchell & Dickinson themselves are professional and courteous. Everything was well planned and programmed in advance and, as such, the job progressed accordingly. Their quotation was very transparent and well costed so there was no arguments over what was and was not done as the job progressed. To their credit, they returned to touch up a few items after the job had been completed and went out of their way to ensure I was satisfied with the end product.

This is not cheap but that is the nature of the product & service being provided. It needs to be viewed as a longer term investment albeit the benefits will be appreciated immediately - thermal improvement and noise reduction.

We couldn't find anything good until we found CosyGlazing

We looked everywhere for a solution and couldn't find anything that looked good until we found CosyGlazing, and some of the quotes we had were vastly expensive. But what you have done is better than I expected, with good soundproofing too – it's amazing. I think it’s a fantastic job. Much better than I thought it was going to look, I must admit.


The work carried out by the team was superb and we are really pleased with the standard of fit and finish. Our aim will be to have the remaining windows completed around Easter time.
