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.

Exceptional

M&D undertook a project to restore and install secondary glazing to three large sash windows in my Grade II listed flat. From start to finish the service has been impeccable, the survey and workmen were all friendly and highly knowledgable. I am extremely pleased with the final result which is subtle and in keeping with the property. I can highly recommend them to anyone wishing to reinvigorate their property.

Windows Upgrade

Undertook a large scale project, to repair, renovate and secondary glaze all the windows in our Grade 2 listed house. The workmen were a delight to have around and they did a superb job from beginning to end. Lots of innovative problem-solving!

High-quality work on a listed property

Mitchell & Dickinson installed secondary glazing and repaired many windows on our Grade II listed farmhouse. We were really pleased with the quality and care they brought to the job. The work was sensitive to the character of the building, and the results have made a big difference to warmth and comfort. Highly recommended.

Yes a job can be too small to consider !!!

I was called i. Response to my request to repair a small window in my Grade 2 listed property. The person that called said that he would probably only be able to help if it was part of a larger repair/renovation project. I thought that was very short sighted of them. Particularly as I am retired and of limited funds. Why couldn't they just fit in a small job - left me with a bad feeling towards the company!

Your reply only shows how disinterested in my request you were. I didnt receive any advice from you or recommendations. You dismissed my enquiry as being too small for you to be interested.

As insulation specialists, we focus on installing our energy-saving solutions in listed and period homes, as our mission is to save carbon and reduce energy bills.
Our policy is to give good practical advice when we aren’t able to help with an enquiry, as our approach is not always viable from a cost or lead time perspective.
We are sorry that we weren’t the right company to help with your small window repair and hope you were able follow-up on our advice of finding a local joiner.

I can't fault Mitchell & Dickinson.

I can't fault Mitchell & Dickinson.
The whole experience from start to finish was trouble free. Arturo and Tom who came to do the work were very polite and worked around us with sensitivity as we were continuing to hold clinics throughout. They were clean and tidy, and made the works as stress free as possible.
I won't hesitate to use them again for the next phase of remedial work.
Thanks you so much

this is what you need!

Right from the start where Jay gave a very intelligent oversight of what we could do to our draughty georgian house, through the excellent customer service and the fitting it was great. Luke and Zac were excellent in rebuilding our windows. Thoughtful, keeping us informed and a pleasure to have in our house. The work looks great.

Excellent experience

We have just had Mitchell & Dickinson install secondary glazing throughout our Grade 2 listed house. We have an eclectic mix of windows (sash, casement, sliding and french windows) and have put up with draughts and condensation through the winter for years and we struggled to open a number of our windows. The M&D team have been excellent from start to finish with real craftsmanship and a sensitivity to working around us and our family home. The sash windows have been expertly restored and open beautifully and we are very impressed with the end result. Thank you.

We had secondary double glazing…

We had secondary double glazing installed by Mitchell and Dickinson last September so we have now been through three seasons. The whole process from first enquiry to completion was without fault. The survey was excellent and the team who came to do the work were excellent. We only use the property part time (not being there was useful, they bring a surprising amount of kit!) but this was to prepare for a full move this year. We were kept up to date with any installation issues that occurred. I don’t know whether it is psychological but with an extra layer of glazing the house ‘felt’ warmer when we were there during the winter and I think it has helped with heat retention on some big sash windows. We had an issue with condensation. This has not been completely resolved, probably about 90% so nearly there.

The end result is elegant and the engineered and draft proofed windows glide open and shut with ease. The house was left neat, tidy and clean.

These windows were not cheap, but this is a high quality product. I am happy to give five stars

Superb product and service

We are more than satisfied with the outstanding job done by Josh and Matt earlier this month!
The whole process was seamless and the results outstanding. What incredible craftsmen and their meticulous attention to detail could not be improved.
They were a pleasure to have in our home.
In fact the whole process from quotation to survey to installation and all communication with the office has been clear and friendly.
We look forward to experiencing more warmth and less condensation on the historic windows of our Grade 2 listed property without any compromising on the beauty of the original windows.
They are also easy to open and close now.
Thank you for providing and installing such a remarkable product.

The team worked really hard to finish on time and were helpful, respectful of our privacy as well as being super friendly. I wouldn’t hesitate to recommend Mitchell and Dickinson to my friends. It is an expensive project but well worth the cost in my opinion.

Excellent!

The whole experience couldn’t have been better. Luke and the team did a great job transforming windows which we daren’t open into ones which have made the flat look the best it’s been. The flat has been left spotless. We weren’t living in the flat but we were kept uptodate with photos. I couldn’t recommend Mitchell & Dickinson more highly - a very professional, respectful and experienced company.

From our first contact with Mitchell & Dickinson, everything has been done with first class efficiency. Contact from the office has been very good and informative and the workmen coming to assess, measure and then fit the CosyGlazing to all our windows has been second to none.
Ben and Kane, who actually fitted it all for us, were very clean,tidy and professional throughout.
We are more than happy with the glazing, it looks fantastic.
Happy to highly recommend Mitchell & Dickinson.

An excellent service

A really excellent service from Harry, Nico and Egan. They did a very professional job with painstaking attention to detail and working round the vagaries of our home life - including a new cat! The Cosyglazing finished product looks really smart, very unobtrusive and in keeping with our Grade II cottage. Now we need to wait for a frosty day to see/feel the full effect of the secondary glazing.

Impressive

I don’t normally leave reviews, however we have now completed two phases of work with Mitchell & Dickinson. Both experiences have been faultless, from the initial enquiry through to the teams that installed the CosyGlazing and the insulation we had fitted to the vaulted ceiling in our bedroom. The craftsmanship is impressive and the team were all polite, efficient and kept everything clean and tidy. We are already noticing the benefits – our farmhouse is so much warmer.

I have been very impressed with the work Mitchell and Dickinson have done. My house is not only much warmer but the secondary glazing is discreet and tasteful. Particular thanks go to Arturo and Peter for being so efficient, reliable and pleasant.

Greedy

They start doing my windows and middle of my project they left for two weeks and go to another project, letting me really down!! I have renovation going on in my house and it’s costing me massive delays!! When I spoke with the boss he simply said we have not enough people , but we have other projects waiting for us, and so you have to wait !! Outrageous!! Greedy !! They weren’t flexible either- they said we won’t work with other builders in a house ( which they doing bathrooms!!!) ., Awful company, so regret engaging with them , was VERY Stressful experience!

Reply from Mitchell & Dickinson

We are very saddened by your review which we don’t feel is a fair reflection of the circumstances.
As you mentioned, the presence of other trades at your property during our installation was unexpected and created challenges from the outset. We did communicate that this could cause delays due to the limited space available.
Additionally, the scope of work increased during the project, and working with period and listed properties often presents unique challenges. We are committed to maintaining the high quality of our craftsmanship, which is why we employ and train our own team rather than outsourcing or bringing in additional trades when projects run over schedule or when there are unforeseen circumstances. This may cause delays, but it means that we can guarantee a high quality of work that is second to none.
We strive for 100% customer satisfaction, and it is disheartening to hear that your experience was stressful.
However, we are pleased to know that you were satisfied with the work completed by our craftsman to your windows which you said are now working beautifully, and we appreciate your positive feedback in that regard.

An excellent job

It has been a pleasure to deal with Mitchell Dickinson.
Everyone I spoke to has been knowledgeable, helpful and charming . The team fitting the secondary glazing did a wonderful job, taking enormous care with every detail. They were also kind and considerate and very tidy.
The secondary glazing has made a huge difference; I no longer have any condensation and the house feels warmer and quieter.

Quality Craftsmanship at a Price

Extremely professional, skilled craftsmen who were extremely sensitive to the look of the windows, ensuring that the glazing was sympathetic to the period features.

Phase 2 Secondary Glazing

Mitchell and Dickinson’s team returned in early January 2025 to complete the secondary glazing in my listed home which can’t be double glazed. The team were a pleasure to have around and worked hard. As before, I was impressed by their knowledge, craft and professionalism and their consideration. The system, for both my sash and casement windows as well as static windows and also the draught proofing of my doors is excellent. It was described to me by a visiting energy efficiency firm as “The Rolls Royce of Secondary Glazing”. Certainly it has made a big difference to soundproofing and the house retaining its heat. Thank you.
