The issue was a broken gearbox on a closed uPVC door, with concerns that a second door was close to developing similar issues.
Stephen arrived quickly at the time advised. Quickly solved the problem, opening the stuck door and replacing the broken parts, adjusting the door to prevent future issues, and carrying out the same on the front door. Both doors feel like new! The work was completed in record time and to a high standard. I would definitely recommend and use again.
