We have used KJM for a few jobs in the last few months. We can’t recommend them highly enough. Superb service, from the whole of the team, from beginning to end. The front door was a bit of an emergency so Paul squeezed us in for measuring up, and Emma offered us the first opportunity available for installing.
Josh and Charlie fitted all 3 jobs, and were very tidy, friendly and respectful, really nice guys. Great service & great products – we will be going back to them to replace the rest of the windows when we are in a position to do so.

Recently had a new door installed by KJM and cannot fault them at all. From start to finish the whole team was professional and so easy to deal with. Kept us updated throughout and the fitters were great – we have a vulnerable adult living with us and the fitters even took time to ask if there were any considerations for them ahead of the work.
The work was done ahead of time and to a great standard and we’re incredibly pleased with the result. Won’t hesitate to use them again and recommend to others – a shining example of top-notch service.

Great team to engage with! KJM were a referral and were very easy to deal with, knew the products, discussed our options and very fast to respond to any queries or similar. The product is great – does exactly what it should and we couldn’t be happier with the service.
The fitting team were excellent, no mess, no rubbish left behind and always polite, professional and real grafters. It’s unlikely we will need to replace these windows or doors, but if we ever move, I would be straight back onto KJM to replace them in the new house.
