The work Michal carried out far exceed expectations. Our back door was tired, damaged and in need of restoration. With the works complete, the door looks brand new and the standard of finish is high. All in all, a great job done at a very good price. Would highly recommend!


Michal is an expert window repairer who does what he promises and does it very well. He works hard and does so in an organised manner, cleaning up at the end of each day. He is a polite and pleasant guy and I would definitely recommend him!

I am so blessed to be able to work with Michal and his team at MD Sash Windows. Even though I felt this job was very small, it was obvious that your company takes great pride in the detail of the finished work. I would say that you exceeded my expectations.

Lucy Bains

We recently had our windows renovated by MD Sash Windows and we are delighted with the outcome. I could say that I was very nervous about having this done. So, I did a lot of research and we found out about MD Sash Windows, it was very impressive and they actually turned out to be what they said they were going to be.
