Mitchell & Dickinson Opiniones 

Josh and his team were very professional and creative when installing secondary glazing for our Edwardian Crittall windows with multiple leaded glass panes, requiring the construction of additional wooden frames to hold the acrylic panels in place where the cast iron handles on some of the casement windows protruded too much internally. They all worked in a polite and unobtrusive way until satisfied the job had been finished to a high standard and made sure no debris was left behind. Condensation problems ceased immediately and the house is now noticeably warmer.

We had most of the windows in our flat secondary glazed and repaired over the summer. We chose Michell & Dickinson because they were able to do the work without scaffolding (we're on the second floor), they said they could repair the leaky window sill, and their reviews seemed promising. Overall though, we have been very disappointed with our experience with Mitchell & Dickinson.

The problems started as soon as we got back home (having moved out to make the work easier). Something had been dropped on a radiator under a window, resulting in a dented and leaking pipe and no boiler pressure. Mitchell & Dickinson reimbursed us for the costs of repairing the radiator pipe as well as plastering the wall that had to be cut into during the repairs, however, they did not let us know at the time of the damage and instead left it for us to discover when we got home. Then it rained, and we discovered that the leak in the window that we had specifically asked several times if it could be fixed had not been fixed, and was in fact worse than before. During both the initial quotation visit and the specification survey this leak had been pointed out and we had been assured (by two different people) that it would be fixed by replacing the window sill. After we discovered it was still leaking, Mitchell & Dickinson representatives said that replacing the window sill was not a guaranteed fix and that window leaks such as these are difficult to fix in general (note that this had not been said before the work began). They sent out someone to put in some more sealant, and we also asked them to fix a different window which had become progressively harder to open (they had added too much wood to the sides, which they then had to remove). Again, when we had the specification survey we highlighted that some of the windows swell in wet weather and were reassured that they'd made a note of that and assured us it would be taken into consideration during their work so it wouldn't be a problem going forward.

Unfortunately the window is still leaking, and we have given up on getting Mitchell & Dickinson to fix it - as one of them said over the phone, they are insulation experts, not window experts. The other repair work on the windows is patchy, made more obvious by the very white paint they used on the repaired areas that does not match the rest of the windows. There are some areas that were missed by the paintbrush, and some of the window catchments are rough and appear unfinished. The secondary glazing has been fine though, it has reduced the condensation issues and the flat seems less drafty. Overall though, we would not recommend Mitchell & Dickinson for window repairs. As they said themselves, they are insulation experts, not window experts, and this shows in our experience with them.

The double glazing product is great. Unobtrusive and effective and you don't have to take it off to be able to open the windows.

The installation team were super. Helpful, efficient and very customer friendly.

The only reason I didn't give them 5 stars was because their scheduling of the work needs improvement. We pencilled in a date for the work to be done 6 months in advance and M&D ended up starting about 7 weeks late. To be fair, once they started they didn't leave the job and we were very happy with the work they did and the back office staff were always very friendly and helped as much as they could.

Excellent response when we needed some new hardware and had also experienced a problem with one window. Super, professional customer service.

Delighted with the work carried out on my windows by Mitchell & Dickinson. The cottage immediately felt much less draughty and a lot cosier. It also felt considerably quieter. Will and Joe are a great team, always considerate towards us, they took care of the property, were punctual and genuinely happy to do a good job. Left everywhere spotless. Have already recommended M&D to friends who are now planning to have their windows done.

I cant recommend this company highly enough. We have an old listed house, with mullioned windows - no line is straight. One floor to ceiling arched window was particularly challenging because it had curved frame. Luke's craftmanship and attention to detail was exemplary - he took a real pleasure in doing the job to a very high standard. The Mitchell and Dickinson team were very helpful in correcting a problem at survey stage and while we had a long wait for them to do the work, it was more than worth it. This is a rare company which believes in what its doing - energy efficiency in old buildings. I am full of admiration for their high standards.

Very professional, cheerful craftsmen. They did a great job installing secondary glazing, and made a complex job very simple.

The long lead time (6 months) led to a few minor hiccups on the admin front but nothing that wasn’t put right.

We had secondary glazing installed on all our windows and some internal doors back in March. We were very happy with the team and have noticed a significant difference this autumn in terms of noise and cold. Unfortunately we are having some problems now with one of the internal doors, and we have been trying to get a response from the Mitchell & Dickinson team for the past 5 weeks. After 4 emails, no one has yet come back to us to get it sorted. This is very disappointing, especially as we were told after installation that we could contact the team with any problem or question. We have also been helping the Sales team by showing our windows to prospective clients a few times as a favour.

Same team for me as the 3rd October reviewer: professional, hardworking and a pleasant experience.
I have large Georgian sashes (first floor Georgian terraced flat) and I would also echo the comments about the secondary glazing being unobtrusive. It was also the only product that I could find for large windows that allowed both sashes to open and could be fitted with working shutters in place. Not cheap, however I’m looking forward to there being considerably less heat loss through the large area of thin crown glass as we get into the winter months.

MandD refurbished, draught proofed and secondary glazed over 30 windows for us and a couple of doors. We chose M and D as wanted a single company that could do all the work and wanted the system where I can use the windows as intended i.e. the secondary glazing is fully integrated.
Very happy with the final product, the quality of the repair work, and glazing etc.
Considering we had many of their people on site for a number of months they were very easy to have around the house.
I have docked one star as initially our painting work was sub-contracted due to the size of the job. These decorators were simply not up to scratch. MandD removed from the job and did the work themselves. Final product good but it did mean our job overrun and a bit more hassle to hit the right standard but I would not let it put me off highly recommending to others.

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 - 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!

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.

Full insulation of all our windows and loft - great job by Mitchell & Dickinson - super professional and a lovely team

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!

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, 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: 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.

A very pleasant installation process which the team undertook with the minimum of disruption. The end result is exactly as expected, and looks great.
