Jmi
Kevin took over the running of JMI from his father, John Masefield back in 2000. He's Ex-Navy, a perfectionist, and a font of all knowledge about pretty much all things windows. Always on hand when you need him. Dean has been an integral staff member at JMI since 1999 and he's a real people person.

He surveys, orders and schedules all the incoming work and looks after the installation teams. He can often be seen out and about on site, chatting to customers and making sure everything is running smoothly and all is going to plan. Sharon has been with JMI for over 20 years and is either in the showroom or out and about meeting customers to discuss their projects.

Dreadful. Poor aftercare. It took 3 calls to have a repair booked. Waited over an hour with no show. Called the office to be told repsir engineer did not realise the time and would be another hour. Ihad booked the morning off work for the appointment. Repsur only needed as a second hand handle had been used on the initial job. Will never use again or recommend

Hi Kevin,
Once again your guys were exemplary in both their professionalism to the job and cleanliness.
We have yet again had several passers by compliment us on how the house looks and I would expect you to get a few calls.
Thanks

Fantastic service from ordering to fitting!! The fitting guys in particular did an amazing job right down to the little finishing touches, even tidied everything up before asking me to come out and check it!! It’s hard these days to find such honest and professional workers! As for the price, they gave me the best quote out of 5 different companies, can highly recommend JMI!

Very helpful and friendly service in their showrooms, without being pressured, and plenty options and able to see examples of the type of doors and installations. Had work done by very efficient installers who did an excellent excellent job. They maybe a little more costly than some other firms but worth the extra. Very pleased with their service.

JMI replaced a number of windows for us, including a large set of French doors and our stained glass stair windows. These were terribly warped and we thought they would have to be replaced. Sharon assured us they could be restored and then put in a new triple glazed unit. We had temporary units in while the restoration took place. The restored stained glass triple glazing units were installed last week and they look absolutely fabulous. It was definitely worth the expense, and the wait.
The windows are of the highest quality. The fitters spotted a problem on the install - we did not ! - on the
