A really enjoyable experience from beginning to end. Matt, Pieter and Gregor were incredibly professional, spectacularly tidy for a potentially very messy job, and the finish of the windows and installation have been superb. We replaced our single glazed sash and case windows with double glazed sash and case and it has transformed our house into a much warmer and pleasant home; no more wet vacuuming our windows. Order process and online platform worked well to track quotes and payments which made it very easy to manage. It's refreshing to come across a business that is run so well.

Matthew and his team (Gregor and Pieter) restored 11 sash windows, dating back to 1858. The works were conducted in a highly professional and efficient manner, and with minimum fuss or disruption. A very high quality finish, I am delighted with the results - the windows look and operate like new. If you need a first class job doing, look no further than MWM Matt Window Mate.

First-class tradesmen who arrive as agreed, tidy up after themselves and are meticulous in their work and attention to detail. Add in that our project included the various Covid lock-downs and you get an idea of how impressed we are! Our windows, storm doors and front door have a completely new and fresh look - they are re-born. Matt takes a keen and active interest and is regularly present or always available and his crew, Gregori and Piotr, were great ambassadors for the business. Do not hesitate to use their services.

Matt and his team were efficient, polite and fitted new double glazed sash windows with original stained glass that now look like new. I can thoroughly recommend them to anyone looking to replace old windows. We now have warm rooms with drafts gone and very smart looking windows.

Matt and his team have now refurbished sash and case windows in our property. They have done an excellent job, carried out by skilled workmanship. Matt is very pleasant to deal with. We had a very small issue with one of the windows and Matt arrived within 30 minutes of me contacting him to resolve it. We still have other windows that require his input and will not hesitate to use him again.
