The experience throughout was of the highest quality

This was the second job that we’ve had M&D do for us and, as with the last job, the experience throughout was of the highest quality: clear communication about the works (including specific clarification about how to resolve an issue with overly wet woodwork); polite, reliable and friendly employees; clean and tidy job; and of course, excellent results.

Before the CosyGlazing was installed we were using 4 bags of coal a week

We are too hot all the time!  Before the CosyGlazing was installed we were using 4 bags of coal a week. As soon as they had finished the installation of secondary glazing, draught proofing and loft insulation, out coal use dropped to 1.5-2 bags a week. It’s heaps better.  It also sound proofs the children’s bedrooms so they don’t get woken up by heavy footsteps in the street. It’s February but  the children say “it’s like summer in the house mummy.” They can go to the bathroom without getting wrapped up in towels first.

If only all tradespeople could be this good. 

M&D are in a different league to most installers. Second time using them and exceptional service as before. From start to finish you feel in good hands. Tony and Josh were polite, courteous and left no trace of their amazing work. I could not recommend M&D more highly; if only all tradespeople could be this good.

Very nice people to deal with and we’re very pleased with the results.

Mitchell & Dickinson draught proofed six casement windows at our home and added secondary glazing. Very nice people to deal with and we’re very pleased with the results.

We can instantly see the benefits and I can highly recommend M&D.

We have a listed building with many single-glazed windows. We were losing a lot of heat, had terrible draughts, the windows wouldn’t open and close, and we heard a lot of noise from outside. M&D tackled all of these issues by carrying out general restoration work and installing CosyGlazing. The team were professional, respectful and understood how to work in a property with many quirks. While older properties will never be perfect, the work carried out has eliminated/heavily reduced the issues. We can instantly see the benefits and I can highly recommend M&D.

Neat, tidy, unobtrusive and will hopefully cut our energy costs.

We chose secondary glazing with some trepidation as our 17th Century mullions are beautiful and we were worried about spoiling them. We are delighted with the result: neat, tidy, unobtrusive and will hopefully cut our energy costs. Luke and his team were a pleasure to have in our home. They have a great work ethic and took care to make as little impact on our lives as possible. They were always bright and friendly and meticulous in their work.

Their craftsmanship and professionalism was peerless.

We live in a draughty early 19th century grade II listed thatched cottage, no surface is level, no window straight, and no wall vertical. Legislation limits what we can do to rectify any of the above and ‘routine’ work can prove to be anything but! Set against this background we approached Mitchell & Dickinson with a degree of trepidation.

We needn’t have worried. Everyone we have had dealings with has been cheerfully professional and incredibly reassuring. Every step happened when it was scheduled to happen, no chasing up, no wasting time waiting for a call. We had two surveys and ample opportunity to ask questions. When I pointed out our wonky windows to one technician his reply was ‘don’t worry, wonky is what we do’!

The day came for the work to start…again bang on schedule. The work took a fortnight, Brett was with us all the time, George for the first week, and Gary for the second. Their craftsmanship and professionalism was peerless, but better than that they were the tidiest and most considerate craftsmen we have ever encountered. Put simply they turned up, cracked on, cleaned up and left – never leaving a mess and never leaving the house unsecure.

The quality of the secondary glazing is outstanding. All our windows now fit. We amuse ourselves by seeing if visitors spot the plexiglass (they don’t). We are delighted thank you!

Impact on temperature in the house and don’t notice the secondary glazing.

Tony and his team fitted ten windows with secondary glazing for us. We are very happy with results and the service received. Fitting was performed very efficiently on a wide range of windows, with careful colour-matching, etc. We’ve noticed the impact on temperature in the house (Georgian cob construction, Grade II-listed) and don’t notice the secondary glazing itself. There were some minor issues with two windows after fitting, but these were efficiently and effectively addressed by the team, with Tony himself returning to rectify in under an hour.

Experienced in heritage properties, with high-quality products and craftsmanship

We moved into our Grade II-listed cottage in January 2021. It was built in 1885 and is a Tudor design with brick (cavity) walls downstairs and timber construction upstairs.

Listed buildings have been exempt from EPCs since 2013 but I found a 2011 EPC with a G rating (worst). I could see from our viewings that the previous owners had not invested in energy efficiency improvements. Two weeks after moving in we had a visit from the ‘Beast from the East 2’. I took some thermal images and could see that our home was glowing and heating the sky!

There are many myths regarding what works and improvements owners can make to listed buildings, so I researched the Historic England library and the secondary glazing market. Before placing the (Phase 1) order, I contacted the New Forest National Park planning department and received a letter back from their Buildings and Conservation Officer advising:-

“Listed Building Consent and Planning Permission are not required to install secondary glazing, so the contractors (Mitchell and Dickinson) can be engaged for the final measurements and installation at your earliest convenience. The company are clearly experienced in working on heritage properties and their products and craftsmanship are of high quality, suitable for use in listed properties.”

From Sales (Dan, Ed and Kirsty), Planning (Rachel) and Installation (Dominic, Will and Matt), we have found M&D to be very helpful and professional throughout. Listed Buildings are individual, so will throw up obstacles requiring project managers to think on their feet to find solutions. Dom was served a number of curveballs but he remained calm throughout, and identified cost-effective solutions.

Payback for Phase 1 was calculated as 4.9 years – this was before our electricity and LPG went up by 50%. It is early spring and we have had a few cold mornings. My wife and daughter have commented that the house feels warmer already. We are very happy to recommend Mitchell & Dickinson’s insulation solutions for period or listed properties.

July 2021

We look forward to a much cosier winter.

I don’t often write reviews but I can thoroughly recommend M&D. The office staff were extremely efficient and Tony and Josh, who fitted our secondary glazing and insulation, did an excellent job with enthusiasm and great attention to detail. We are very happy with the result and look forward to a much cosier winter.

We were delighted with the work undertaken at our cottage. Mitchell & Dickinson employees proved to be helpful, highly skilled and very pleasant to deal with.

They really made the effort to make sure the space was cleaned each night. 

We had a couple of quotes for secondary glazing, and although M&D were overall more expensive I think it was worth it. We also had the insulation work completed on the windows which I believe will help during the winter. We suffered with a lot of condensation, after the works it hasn’t completely gone but we can definitely see a vast improvement, only a slight mist now. All of the team have been very helpful. Kirsty was excellent in providing the initial information. Kai and Keith were amazing. They are true craftsman who are passionate about the work and service they provide. It is messy work but they really made the effort to make sure the space was cleaned each night during the project work. I would not hesitate to recommend M&D for insulation and secondary glazing work.

The window system is great.

The two-person team who did the install were friendly, tidy and have done a very neat job. They also had to lug their gear up and down the lane from the high street (due to parking limitations) and did this all without a grumble or complaint.

All in all, I am very happy to recommend. The window system is great, condensation pretty much eliminated, it feels warmer already and it does a decent job of noise reduction.

Their employees are delightful, courteous, fun and brilliantly competent. 

M&D have done secondary glazing and loft insulation. Also dry-lining – a layer of insulation board on top of the existing plaster-board wall. Their employees are delightful, courteous, fun and brilliantly competent. I am always slightly sad when they leave! Expensive, but on balance worth it.

February 2023

From the outside it is impossible to tell we have secondary glazing.

Excellent job. We have just had CosyGlazing fitted to six windows. We were slightly nervous that the new glazing would detract from the appearance of the existing windows (which are old wooden sash windows – great to look at, but hopeless when it comes to insulation!). However, our fears were completely unfounded – from the outside it is impossible to tell we have secondary glazing, and even from the inside the windows still look good. The team were also very friendly and tidy, and we had excellent communication from head office. Very happy with the result.

June 2021

A near invisible system of secondary glazing in a listed building. 

Good communication, and honest, reliable fitters. Any problems were dealt with promptly and without fuss. A near invisible system of secondary glazing in a listed building. We look forward to a cosier winter.

We are extremely happy with our choice.

We were extremely happy with the job Mitchell & Dickinson did. They were more expensive than some other companies but they clearly offer a far better product and we are extremely happy with our choice. Luke, Zac and Jack (the installers) were lovely guys and it was no bother having them working in the house and they made the process as easy as possible. Thank you.

Improving the energy efficiency of an ancient house.

The house is an ancient Dartmoor longhouse and the windows were crooked and very weathered, and in a pretty bad state. They now look terrific. They open and close easily, the drafts are all gone and the secondary glazing is almost invisible. We had struggled long and hard to find a way of improving the energy efficiency of an ancient house without destroying its character and were so relieved to find Mitchell & Dickinson’s perfect solution.

April 2023

A significant improvement to a once very draughty entrance hall.

Fitted CozyGlazing to our Victorian cast iron diamond paned windows. The product is almost invisible from the inside. M&D also fitted draught proofing to the Victorian oak front door, which has made a significant improvement to a once very draughty entrance hall. The installation team were fantastic, attention to detail and quality was exceptional. The team were in the house for two weeks but were very neat and tidy and self sufficient.

We are delighted with the CozyGlazing.

We would highly recommend Mitchell & Dickinson. We had restoration work carried out on the wooden window frames in our listed cottage and CozyGlazing fitted after. Kevin and John, the two craftsmen, were punctual, discreet, informative and highly skilled. We are delighted with the CozyGlazing which has solved the problem of draughts and heat loss, and they look good too. We wouldn’t hesitate to recommend Mitchell and Dickinson, or use them again ourselves.

The work was of a very high standard.

I have recently had Mitchell & Dickinson refurbish and fit CozyGlazing to the two sash windows on my Grade 2 listed building. I found the all of the people that worked on this from the office staff to the three guys who did the work to be extremely helpful and informative. The work was undertaken with the minimum amount of fuss and everything was left clean and tidy. The work was of a very high standard and I would highly recommend them to anyone who requires this type of work to be undertaken.

The team were polite, efficient and clean.

We had sash windows insulated, which involved releasing the ones that were painted shut, adjusting all to fit well, fitting brush draught excluders, fitting secondary glazing, re-weighting, refitting and retouching. Similar work was done to multiple casements, including sealing some shut. The front door was also insulated as it was badly fitted and leaked like a sieve. The secondary glazing is wonderfully discrete – not at all obtrusive. The team were polite, efficient and clean, leaving no mess behind. We are already noticing the difference to both thermal insulation and noise reduction.

We are now considering having them return to do two more of our sash windows.

Tony and Matt were our superlative team of installers who finished a four day job in our 18th century cottage last week.

The quality of their work and the finished product is exceptional – refurbishment, draughtproofing and secondary glazing to two sash windows and one metal casement window that it is almost invisible and yet highly effective against traffic noise (and almost certainly heat loss though too early to tell at this stage).

Tony and Matt were delightful and left the rooms where work was completed, and our garage which was temporarily their work shop, clean, tidy and entirely as they found them. All promises and timeframes were met and the office team were also polite, professional and a pleasure to work with.

In summary, we are so impressed with the effectiveness of M&D’s cozy glazing product and the professionalism of the service that we are now considering having them return to do two more of our sash windows.

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.

Jill M
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.

Delighted with the results from Mitchell and Dickinson

Amazing craftsmanship and attention to detail at every stage of the process, our house is now cosy and warm after having draft proofing and secondary glazing completed on our 200-year-old windows and doors. The secondary glazing is virtually invisible so none of the character of our unique windows has been lost. Although a big investment, I would highly recommend this system as the only and best solution for listed properties that are cold and draughty, and a lot less expensive than replacing all the windows like for like.

Great experience all round with this installation

Having tradesmen in your house for 2 weeks is always daunting but I can honestly say that I couldn’t have been more pleased with how easy the process was and how incredibly polite, considerate and discreet the team was. We are really happy with the end result too and the secondary glazing is both pretty much invisible and really effective. Really recommend Mitchell and Dickinson if you have a grade II house and you are not allowed to change the windows. Thank you so much for keeping us warm!

Bedrooms noticeably quieter and warmer. Draught proofing on front door has also worked brilliantly.

Delighted with our glazing. The bedrooms are noticeably quieter and warmer. The draught proofing on our front door has also worked brilliantly. All workmen were friendly and considerate and incredibly clean and tidy. They worked to an excellent standard, even coming back to ensure one heavy pane was sufficiently supported. Would highly recommend!

Remarkable professionalism

We had half of our windows secondary glazed by this remarkable company when they first started trading some nine years ago and were delighted. This year we were in the middle of a major renovation of our 223-year-old house so decided now was the time to complete the project by asking them back to do the remaining windows. As before, the craftsmen were discrete, extremely tidy, totally professional and very pleasant. And very talented. In addition, they noticed work was needed on a window done in phase one and came back for a whole day to rectify it for no charge. Hugely impressive. Thank you.

May 2022

All three windows are now draught-free and open easily. The room is noticeably warmer.

M&D fitted secondary glazing to our large bay window in a house built in 1881. As the upper sash of all three windows were arched we could not fit standard double glazing as we have done everywhere else. The windows were difficult to open too. The work was excellent, on time and all three windows are now draught-free and open easily. The room is noticeably warmer. The room was well protected and kept clean during the four days of work. Thank you M&D.

May 2022

Pleased with the smart look of the secondary glazing, you wouldn’t know it was there. Rooms feel warmer.

Work teams arrived promptly each morning, neat and tidy in their work and a delight to have around. Workmanship excellent, and pleased with the smart look of the secondary glazing, you wouldn’t know it was there. Rooms do feel warmer but will have to wait until later in the year to feel the benefit once winter is here. Would recommend.

December 2023

Even better than expected

Our 100-year-old listed building on the edge of Exmoor has lots of windows which give it a unique appearance. But in the winter months, it was prone to rivers of condensation which caused mould and rotted some casements. The work that M&D carried out has got rid of the condensation in most rooms and reduced it by 95% in the rest. Yes, the house feels warmer and there is good soundproofing. Draughts were not a major problem but that was because the windows were so tight they were difficult to open. Now they all open very easily which is a joy. The secondary glazing enhances the appearance of the original heritage glass and it is unobtrusive. The three craftsmen were excellent and really cared about the finish.

Big job as my windows needed a lot of restoration. Excellent quality, talented and considerate craftsmen.

So pleased with my windows. A wonderful product that has transformed my draughty house. It was a big job as my windows needed a lot of restoration. An excellent quality of work from talented and considerate craftsmen. Thank you.

Well crafted to each window

Mitchell and Dickinson were polite at every stage. Every window in this house is different and so they painstakingly over 10 days fitted, filled, sanded and painted a bead to each frame. The end result is hardly noticeable but our warmth is. Great people and not a bother having them all around the house for two weeks.

We are beyond pleased with the result

We are beyond pleased with the result of the window repairs, draught proofing and secondary glazing. The house is warmer, drier, quieter and above all more cosy. Harry and Nico were here for almost two weeks, they turned up every morning with a smile and got straight on with their work. Definitely a great team -they just seemed to work away with the minimum of fuss and no problem was too great. Given that they were working in almost every room simultaneously the disruption was minimal. The resultant work is fantastic and we cannot recommend both the product and craftmanship highly enough – thank you Harry and Nico.

Making our beautiful, but cold, Georgian house warm!

Living in a Grade ll Georgian house with huge windows and high ceilings is a joy in summer but a bit of an endurance in winter. We didn’t think we would find any solution until we found Mitchell & Dickinson. They are very popular it seems, so it was some months before we got an installation date but we are so glad we have done it. They put fixed panels on the front of the house (on the road and north-facing so rarely opened) and integrated secondary glazing on the back. We have curved sashes and the team ended up finding quite a lot of rot we didn’t know was there. Nothing was too much trouble and no corner was cut. It is so reassuring to know the windows are now all in good repair. Tony, Chris, Matt and their team turned up early every day for over five weeks – they are professional craftsmen who undertake the work as meticulously and discreetly as they can. They put plenty of protection over carpets and work areas and were unflaggingly enthusiastic and uncomplaining despite the six flights of stairs they were constantly running up and down! We have just had the work completed so time will tell but already we notice the rooms heat up quicker and the heat stays for longer. The road noise on the front is reduced too. As for the secondary glazing itself, it is so very neatly applied and is barely noticeable – if anything, the big panels on the front frame the windows to make them look even more beautiful. It really is the perfect solution for a listed building and they are careful to use the correct materials in renovation – oak, lime mortar, breathable paint etc. Everything is to a very high standard, done by knowledgeable and skilled craftsmen. We are delighted with the results.

Everything went very smoothly, quality product and now we have a much warmer home. I would happily recommend the team to anyone, and they have done a great job for us in our listed cottage.

Should have done it sooner!

A month ago we had a range of windows in our listed property refurbished. Harry and Nico spent 10 days with us, and could not have made the experience easier. They set up their pop-up workshop in the backyard – a very impressive set-up – worked on our windows during the day, and put everything back in place each evening. I admit I was a bit sceptical as to how they would make double glazing look both aesthetically pleasing and actually improve heat retention with our sash windows. Since then we have been experiencing a really cold snap and what a change! We have a log burner, and now our living room is so cosy that we frequently leave the door open. We close it when we go to bed, and in the morning the heat retention is noticeable. An absolute bonus with the draught-excluding system is the reduction in any outside noise, as we are on a busy road. Thank you Harry and Nico for your professional work, and for making the whole experience such an enjoyable one.

What a pleasure it was having your team on site

Thank you for the excellent work done over the last couple of weeks and to let you know what a pleasure it was having your team on site. There’s always a slight dread sharing your house with complete strangers but the guys were brilliant. They tolerated our dogs, worked around us with minimum disruption and were always polite and friendly. So much so our kids insisted on baking cakes for them in the first week and bring home ice creams for them after our beach trip this week!

Of course the standard of work is vital and the work is top notch but having such nice people around makes the whole process so much more enjoyable.

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.
