Trusted Maintence did an excellent job building a bespoke cupboard for my living room. Karl was knowledgeable and took time to understand exactly what I was looking for. His measurements were precise, communication was clear throughout, and the pricing was very reasonable. The finished cupboard is exactly what I wanted, with a well executed replication of period charm. Overall, a professional and reliable service that I would use again and recommend.

Krzysztof did a great job fitting 2 showers, decorating ensuite, changing all the taps and 2 showers, and doing a number of small fixes and improvements in the flat. I appreciate his clear and detailed communication on job needed, options provided, and consulting on fittings and materials. He finished the job with high quality and with just a small delay despite of a good amount of obstacles (we did painting in parallel). Would definitely recommend Chris's services!

Bit of difficulty getting messages answered, but arrived early on the agreed date, which was fine. Completed the task quickly and effectively. The company's terms request payment once the quote is accepted. I pay once the job is completed (unless it's a large job, requiring a deposit, for example.) He asked for cash and I said I preferred bank transfer. He started showing me messages on his phone from people who had paid cash in advance. I said I am not them and I would transfer the money this afternoon.

Quality,reliable and customer focused company. 18 th edition qualified & Niceic registered. 30 years in the trade and lots of experience in all aspects of electrical work from domestic rewires, shops,offices and factories.

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.
