Great serivice by Dorian, he was greatly helpful to understand my objectives for the works needed and the deadlines I had to achieve those. He's spot-on for electrics, but he was outstanding on all-round trading works, excelling also on painting, flooring and plumbing, even if a fully busy schedule during the working week and thus committing flexibly during his extra time on evenings and weekends. Hope to works with him soon again on bigger projects!

I have no issue with the work they did, but they should routinely carry cleaning equipment such as brooms, dustpan and brush and a vacuum cleaner. They should not need to use mine, or ask me for a bucket to mix up plaster in. Finally they really should take their rubbish away or tell their clients the price does not include rubbish removal. Putting it in my neighbour’s bin and on my garden is unacceptable.

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.

Russell attended the site (my home) to discuss the options and provided a prompt and very fair quote which I accepted. The job, (quite significant taking 2 days) was carried out by Jamie and Chris a short while later. They were always very friendly, organised and clean - the work was excellent. OVER A YEAR LATER, and a couple of the lights had stopped working and I contacted Russell. Within 2 days, everything sorted with no charge for the new lights or the service. Amazing service, one of the best!
