Review summary

Created with AI, based on recent reviews

Looking at 30 reviews, reviewers overwhelmingly had a great experience with this company. Customers consistently praise the staff for their professionalism, trustworthiness, and helpfulness, noting their care and attention to detail. Many people highlight the exceptional quality of the work and craftsmanship, especially for listed properties, and are very pleased with the final product. The service is frequently described as impeccable from start to finish, with efficient and tidy workmen who minimize disruption. However, some customers experienced issues with condensation between the secondary glazing and the original glass, and a few found that the rebalancing of sashes did not meet the "finger light" promise. There was also an instance where a customer was not informed about a new UV glazing product that would have been beneficial for their south-facing house.

Just totally impressed with Mitchell…

Just totally impressed with Mitchell and Dickinson. The quality of the work, craftsmanship care and attention to detail were/are all 10 out of 10. Then equally impressive were Harry with his team of Leo, Jo and Ethan - such nice people who genuinely cared about their work - We actually miss having them ruck up at 8am every morning! I'd have no hesitation whatsoever recommending M&D if you have a listed or period property that needs insulated - these are the go to people.

Victorian Townhouse Sash windows

Victorian Townhouse Sash windows - secondary glazing.

After a rocky start with being bumped along for another project, Adam and Chris arrived three months later and were fantastic and the care and workmanship to the windows were spot on. I could not have asked for such an amazing team; and if I were to have more work done, I would not allow anyone else!

(with hindsight January possibly wasnt a good start date as it was freezing).

The secondary glazing allows the windows to retain their features; it is instantly warmer and it provides a cosy buffer to the outside noise.

Only days before the finish date, I received a notification about UV glazing, which would have been perfect for my house as it is south facing and the majority of the windows are there. If M&D know they were launching this product, it would have been great to be aware of it as an option.

Nevertheless, The new replacement Hertiage glass is fabulous - replacing the broken ones.

The actual survey could have been more thorough - ie checking for wood rot etc... so that the end bill, which I am yet tot receive will not burn the wallet.

It is an expensive product, as there are other viable options out there; but for us it is more economical than replacing with new sets of timber windows of double glazing; and we needed to keep the appearance due to the conversation area we are in.

I am sure that as time and technology move on, there will be much opportunity to provide products for Old houses that will outmatch the full cost of total replacement.

Great service, and great product.

Thank you Adam and Chris!

Expert work to insulate and restore the windows in our Grade 2 listed house

We were very pleased indeed with the work to restore the sash windows in our Georgian house and to remove draughts and add secondary glazing for insulation. The expert craftsmen, led by Dominic, showed such care and sensitivity to the history of our house. The secondary glazing is indeed very unobtrusive, and we were so pleased we took this option to improve insulation. I can honestly say it exceeded our expectations.

Well organised

Well organised. Staff working at the house very professional and completely trustworthy. The work by the nature of what is being carried out, is invasive to normal routine and use of the house. Staff worked to keep this to a minimum. The windows now are virtually draught proof and noise from outside is greatly diminished. We are very pleased with the work and attention to detail. We would highly recommend this company and especially the staff working in the house.
Those working “at the coal face” deserve praise indeed.

Sash Window Refurbishment

Overall a good service from start to finish. The Admin Team regularly kept us informed of the progress of our order. The craftsmen that undertook the refurbishment works on site were quick, thorough and clean & tidy.

Secondary glazing in a grade 1 listed house

M&D installed secondary glazing on grade 1 listed leaded windows. The installation needed to be removable without damaging the original fabric and as invisible as possible. The end result exceeded my expectations. Our rooms are easier to keep warm and the glazing is barely visible.

A first rate job and a great solution for period windows.

My husband and I commissioned Mitchell & Dickinson to install CozyGlazing in the front and side windows of our 1920s house as we did not want to compromise the beautiful original stained glass and leaded light windows (including a circular stained glass window in our front door) but needed to do something about the freezing cold temperatures in the front (north facing) of our house in the winter. We had quotes from other secondary glazing companies, who were only able to offer very inflexible and less than pretty options to solve the problem. Mitchell & Dickinson refurbished and draught-proofed our windows, before installing CozyGlazing.
The wonderful Dom was just amazing - a real craftsman with a genuine desire to make sure that the finished result was as good as it possibly could be. He was always helpful and considerate - disrupting our lives as little as possible (we had additional challenges in that the work was being done in January while we had temperatures well below zero and our central heating broke down during the process, so not the best time to be having windows removed to repair and draught-proof them!). In short, he was a pleasure to have around and made the whole process as easy as it possibly could have been.
Now that the work is complete, we are delighted with the result. The front rooms of our house are notably warmer and the severe condensation that we used to see every morning on cold days has decreased markedly. What's more, the CozyGlazing is very discreet, invisible from the outside and almost unnoticable on the inside.
Our only negative about the whole experience, was (as others have said) the length of time between paying the deposit and work actually starting and the rather confused communication between ourselves and head office when trying to get the final quotation for the work.
But all in all, we are absolutely delighted with the end result and will definitely recommend the company to others.

Top Quality Double glazing solution

So pleased with the service, the friendly staff and the final product. We have a listed property and got the green light for this solution from the planning office and are very pleased to have a solution that makes the house feel so much more cosy and also looking good. Great product. Very Pleased. Ben

Highly recommended

The CosyGlazing design and implementation was first rate and I could not have had better. I was especially impressed by the high degree of draught-proofing carried out on my Grade 2 Elizabethan house with many windows fitted with a variety of mid-19th century frames and old glass, and a few on-site adjustments. Paul and his team were experts and professional and friendly throughout. Paul gets extra praise. Highly recommended.

Superb work renovating windows and installing CosyGlazing

Tony and team have just finished renovating a mixture of casement and sash windows in our grade 2 listed property, as well as installing CosyGlazing. Nothing but the highest praise from us for the quality of workmanship, which was exemplary, the professionalism and how they kept us informed on progress along the way. The finished product is spectacular in terms of look and finish, and the CosyGlazing makes a discernible difference in terms of heat retention. Thank you to Tony and team for a job very well done, and the wider team at M&D along the way.

Great Product and Craftsmanship

We had a great experience having our sash windows renovated and draft proofed. We were very impressed by the quality of the work and the team craftsmanship.

As the windows are removed during the day I would in future plan the work to be done in the summer.

Very Impressed - Tony is an absolute star!

The entire process was incredibly positive, from booking in the works, staff support, understanding the scope of the works, to the communication leading up to the start. Tony did an incredible job and showed such care for our home. He was kind, helpful, and went well above to ensure the window was restored to the best version of itself. We will absolutely work with Mitchell & Dickinson in future for projects on our Grade II listed house!

Very professional and reasonable

Mitchell & Dickinson were very professional in their work, kept in constant communication and I am very satisfied with outcome. They replaced the rotten wooden bottoms of patio windows exactly to the state they were originally and installed movable secondary double glazing. The professionals who came were kind and careful and gave me good advice.

Friendly and professional team

I had the casement windows in my Grade 2 listed property restored and secondary glazed by Mitchell and Dickinson. Every member of staff I encountered throughout the process was friendly and professional and I'm pleased with the work so far, so would definitely recommend!

Very happy with the outcome and good experience

We had all the windows in our Georgian house refurbished and cosy glazed. The team were always on time, professional and we are really pleased with the good results. Our windows no longer rattle, draughts are excluded and noise and condensation is much improved. The guys were easy to have around, hard working and always left the house clean and tidy, they were with us for 3 weeks. We were very pleased with their work, thanks to John and Ed and the team in the office.

Not as high a standard as portrayed

Installation was handled relatively well, although issues matching window furniture, and a lot of extras over quoted price. Rebalancing of sashes leaves a fair bit to be desired - definitely not 'finger light' as the literature promises - most ended up more difficult to open and shut than before. Condensation issues persist, which whilst not promising a resolution, it doesn't really seem much better than it was. For the cost, it doesn't feel like money well spent on our property

Reply from Mitchell & Dickinson

Thank you for your feedback. We would really like the opportunity to come and address the issues you have raised. It sounds as if the sashes need some further adjustment as we stand by our promise that you should be able to open and close them with two fingers. We would also like to offer some advice on the persistent condensation problems that you are experiencing as, whilst we make no guarantee that secondary glazing will eliminate or reduce condensation, it is important to try and identify the cause for a number of reasons. Please could you make contact with the Customer Team on 01237 870016 so that we can arrange a return visit.

Sash windows with eco-credentials

Our relationship with M&D goes back years. Their way of secondary glazing has enabled us to retain our wooden sash windows but greatly improve their performance and energy-efficiency. Recently we have used them for another phase of window improvements, and again appreciate the quality, appearance and functionality of their work.

Mitchell & Dickinson provide high standards and excellent quality in their workmansip

Mitchell & Dickinson were extremely helpful with the process of applying for listed building consent and gave me a very clear understanding of how my Grade II listed windows would be restored and how their CosyGlazing system would be applied. The standard of workmanship was very high and the team, run by Tony, worked calmly and efficiently with minimal disruption.
The benefit of finally having windows that fit correctly, are draught-free, and have secondary glazing panels to combat the coastal gales is wonderful and I highly recommend their system.

Faultless project

We were impressed with Mitchell and Dickinson from the start to the finish of the project to refurbish and add secondary glazing to our listed property. The explanation of the techniques to be used was crystal clear. Then the specifications and delivery of the work was faultless. The foreman and team were easy to have on our home. We recommend them highly.
