An excellent experience
This was a really excellent experience, having secondary glazing and door draughtproofing fitted. The team, Arturo and Jordan, were extremely professional and helpful, and worked round our various awkward requirements, in terms of the Ukrainian guests we have living with us at the moment. The work was of the highest standard, and we are delighted with the result, having already noticed a difference to our heating needs. What we haven't noticed is the secondary glazing itself which is so inconspicuous that we almost wondered if it had been done! Well done.
Absolutely fantastic
Absolutely fantastic - Tony and the team worked efficiently and effectively to complete our job. They were very clean, courteous and professional as well as being lovely people to have around the house!
Sash window repairs, draught proofing and double glazing
The teams of craftsmen restored, draught proofed and fitted secondary glazing, CozyGlazing, to ten sash windows and two doors. When they arrived in the summer they set up their machinery in the garage and got started. The works took about three weeks.
Kai and his men were a pleasure to have about the place.
I’ve noticed a difference already, we’ve needed hardly any heating…and it’s mid October.
Great stuff.

The team did a first glass job removing and overhauling my sash windows before fitting the secondary glazing. They worked really hard on some very hot days and were friendly and respectful. The finish is really good and my windows are also more secure with the new lock.
great job from Mitchell Dickinson
Full insulation of all our windows and loft - great job by Mitchell & Dickinson - super professional and a lovely team
Great standard of work and expertise
Mitchell and Dickinson have draught-proofed our listed property to perfection! Devoted and talented workforce in Will and Joe who visited us here in Guildford two weeks ago. Now our 500 year old front door has no gaps showing daylight around it! Never thought it could be done - but they have achieved just that! Looking forward to a warmer winter 2022!
Excellent in Every Way
Mitchell & Dickenson came very highly recommended but there is always a doubt until you have your own direct experience. But I need not have worried.
The MD, Tom Coles, made a point of contacting us personally, to discuss our concerns. He then visited himself to conduct the survey. All of this made a very good impression.
The insulation process is long and complex. It involves workmen being inside your home for many days - four weeks, in our case. Again, there was trepidation. Again, I worried unnecessarily. From the first moment they arrived with us, their engineers - Tony and Jason - showed us every possible consideration. They were quiet, careful and exceptionally tidy. Every step was explained to us and our comments taken on board. Above all, they have very high standards, so we always felt we were in safe hands and that a wonderful job was being done.
Mitchell & Dickenson performs to a high level. We could tell that in advance from their literature and the recommendations they received. But this job is always going to be a major expenditure, for everyone, not something you would undertake lightly - even though the times make it all but a necessity. So, you look for indications that you are making a wise decision in choosing a particular company to carry out the work in your home.
I rarely write recommendations. In fact, I can't remember the last time I did. But I am writing this because I want prospective customers of M&D to know that they will never regret their decision. This is one of those companies one hopes still exists - careful, considerate, thorough, highly professional, courteous and - absolutely - not just jumping on the eco-bandwagon to make a quick buck. They have been doing it for a while, long before it was profitable, because they think it's the right thing to do. And I am very grateful for the day that someone recommended them to me.

In June 2022
In June 2022, M&D refurbished, draught-proofed and added secondary glazing to three sash windows, and refurbished and draught-proofed a front door. Listed building consent had been refused for replacement of these. The work was done very efficiently and carefully. The team -- 2/3 people full-time over 9 days, with their workshop permanently installed in one room - were a pleasure to deal with. For the moment (first weeks) we are very pleased with the improved acoustic efficiency and expect significant thermal improvement.
A challenging job
A challenging job: Restoring and renovating two large Victorian stained glass sash windows and adding secondary glazing. The company was very professional and easy to deal with from the start and the installation team were friendly and thorough ensuring that the job was completed on time, on budget and fully to specification. The kitchen is now better insulated. quieter with reduced traffic noise from the busy road we live on, and with better light compared to the old glass secondary glazing. Not cheap but you get what you pay for. Strongly recommended.
Would use again
A very pleasant installation process which the team undertook with the minimum of disruption. The end result is exactly as expected, and looks great.
Great people to deal with
Great people to deal with, both in the office and on-site, clear quote, considerate working practices and an excellent result.
So pleased with my windows
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.
Listed Property Secondary Glazing
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
M & D fitted secondary glazing to our…
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 move as well. The work done was excellent, on time and all three windows are now draft free and open easily. The room is noticeably warmer. The room was well protected and kept clean during the 4 days of work. Thank you M&D.
Delighted with our glazing
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!
Great Product, Great Team - Grade 2 Listed Home
We moved into our Grade 2 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 Beast from the East 2 and 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 Historic England library and the secondary glazing market.
Before placing (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 identifying cost-effective solutions.
Payback for Phase 1 is calculated as 4.9 years but that was before our Electricity and LPG went up 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. As my son says “Happy Wife, Happy Life!”
We are very happy to recommend Mitchell & Dickinson Insulation solutions for Period or Listed Properties

Very positive experience
Tony and his team fitted 10 windows with secondary glazing for us. We are very happy with results and the service received. Fitting was performed very efficiently for a wide range of different windows with careful colour-matching etc. We have noticed the impact on temperature in the house (Georgian cob construction, Grade II listed) but don't notice the secondary glazing. There were some minor issues with two windows post fitting, but these were efficiently and effectively addressed by the team, with Tony himself returning to rectify in under an hour.
Excellent work
Excellent work, kept to time and budget. Makes a big impact to an old house.
Luke, Zack and Matt's team
We chose secondary double glazing with some trepidation as our c17 mullions are very beautiful and we worried about spoiling them. We are delighted with the result, neat, tidy unobtrusive and hopefully will 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 to our lives as possible.Always bright and friendly and meticulous in their work.
Listed property - window insulation improvements
We have a listed building with many single glazed windows. We were losing a lot of heat, had terrible draughts, windows would not open / close and we hear a lot of noise from outside. M&D have completed work to tackle all of these issues, with general restoration work and installing Cosy Glaze. The team that came in were professional, respectful and understood how to work in a property with many quirks. Whilst older properties will never be perfect....the work carried out has eliminated / heavily reduced these issues. We can instantly see the benefits of what M&D have done, and i can highly recommend them.
