I used Jdc building solutions to instal new ceilings , which they completed and did a good job. I also requested a replacement window which I paid ?250 upfront as requested. They arrived to fit the window but it was the wrong size and promised a replacement within the week. 8 weeks later no sign if my window, despite numerous phone calls which they stopped answering , no reply to my correspondence . I have not heard from them since, no refund of my ?250
