Repair Concrete Windowsills & Frames; Restore Windows Windows & Doors (Wooden) MD Sash Windows were fantastic. Their workmanship far exceeded my expectations and I would have no hesitation in recommending them or indeed using them again. Michal and his partner worked tirelessly to restore our wooden windows and concrete sills that had not been touched […]

David Aswani

Michal repaired a whole front of severely damaged sash windows at my house and his work exceeded my expectations by far. He is a hard worker, friendly and easy to be with. The old windows look like new ones now. Thanks a lot for it.


Michal has carried out a variety of work for us: repairing, draught proofing and painting of sash windows and doors, restoration of garden furniture and repair of a small roof. He is a tidy craftsman and we have always been happy with his work.


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!
