James, was polite and professional. He checked our main roof both back and front. Whilst the main issue was with the roof at the front of the house. He explained what and where the issues were. The quote he gave was reasonable for a complete roof replacement. James and his crew worked flatout to strip down and replace tiles, felt, battons and insulation of a two story Terrenced house over a two day period including cleanup. Great job i would consider using them again.

John at Quebuild went above and beyond for us on this job. He completed all the work in a timely manner and for a very reasonable price. He was super knowledgeable and extremely attentive to detail, making sure to leave a high quality finish in terms of decoration - and he came back afterwards to address a few small things that needed doing. He was also a pleasure to have around - and I would highly recommend him for any other work. 10/10.

ended up putting a completely wrong colour of silicon in my bedroom which completely spoilt the look despite him saying it gives a different kind of look. I was completely new to doing a house, so didn’t know what will work and what won’t. Ignoring the choice of colour part, there were smudges of silicon at many places and i wouldn’t call it a neat job per my standards. But each one could have different standards.
