Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Dmitry

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use 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.

Christian is very argumentative, he does not listen to what the customer wanrmts, he looks for the easiest and cheapest material to do the job, he tells you not to tell his workmen how much he has charged you or he will quit the job.he is an extortionist, he overcharges for material, if you buy your own material, he takes what remaining without asking, he is always in a rush and as a result the job is not completed, you have to hire someone else to complete it. For peace of mind, I won't hire him

Good price, friendly guys, flexible on dates when we needed to.move them at short notice, great job, very happy.

*Professional Summary:* After obtaining a degree and purchasing my first home, I quickly realised that I had a knack for DIY and home improvement. This passion led me to retrain in various trades, where I honed my skills and developed a deep understanding of the construction industry. Leveraging my hands-on experience, I transitioned into project management, where I now hold significant qualifications. Today, I use my expertise to bridge gaps in projects as I work towards securing larger industrial contracts. My journey from DIY enthusiast to skilled PM has equipped me with a unique blend of technical and managerial skills, allowing me to excel in both the planning and execution of complex projects. *Business Philosophy:* At our company, we believe in valuing the skills and dedication of our tradesmen. Each team member not only earns a competitive wage but also benefits from a share of the company's profits at the end of the calendar year. This approach ensures that our workforce is motivated to deliver exceptional quality on every project. We don't work cheap; instead, we focus on delivering precisely what we promise, ensuring that our clients receive top-tier results and our tradesmen are rewarded for their hard work and craftsmanship. *Commitment to Quality and Safety:* We take our responsibilities seriously. Our company is fully insured, and our team is highly competent, holding a Safety Schemes in Procurement (SSIP) certification. We are committed to upholding the highest standards of safety and professionalism in every project we undertake. This commitment reflects our dedication to delivering not just quality work, but also a secure and compliant working environment for all involved. Our company operates on the principle that in any project, you can have it good, fast, and cheap—but only two at a time. This philosophy guides our approach to delivering quality work while managing client expectations. If you want something done quickly and to a high standard, it won’t be cheap because quality and speed require skilled labor and premium materials. Alternatively, if you need something done quickly and on a budget, you might have to compromise on the level of quality. Lastly, if quality and cost are your priorities, the project will take time, as we won’t cut corners to rush the job. This principle ensures that we remain transparent with our clients. NOW LETS GET TO WORK!

Dan is a force of nature, as anyone who’s met him will agree. He and his team were always dedicated, hard-working and good natured. I would recommend Dan and his team to anyone, especially for a big renovation project like this, which involves working with other parties, such as structural engineers, kitchen designers and installers, as he works with them and takes away most of the pain. The quality of the work is excellent and he always came back to complete the snag list (even 3x for our thresholds).

We had them in to install insulation in our upstairs floor, replace the sub floor, replace some lights, install a loft hatch, and board out our loft. On top of this they discovered a problem in our roof that they fixed. We were incredibly impressed by all of the staff that attended on site. They were friendly, polite at all times, and worked really hard, to a high standard. I couldn't recommend James and his team more, and we've already started talking to them about a further project.
