We are very happy with the final product, the quality of the repair work and the glazing.
M&D refurbished, draught proofed and secondary glazed over 30 windows for us and a couple of doors. We chose M&D as we wanted a single company that could do all the work and wanted the system where we could use the windows as intended (i.e. the secondary glazing is fully integrated.)
Considering we had many of their people on site for a number of months they were very easy to have around the house. I have docked one star as, initially, our painting work was sub-contracted due to the size of the job. These decorators were not up to scratch so M&D removed them from the job and did the work themselves. The final product was good and, although the job did overrun a bit to get the right standard, I would not let that put me off highly recommending to others. We are very happy with the final product, the quality of the repair work and the glazing.
