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.

In a nutshell, Marius and his team are great. They're kind, respectful and Marius is always available to answer every question you have - he def is the most knowledgeable builder I've spoken to. You get a very transparent estimate and sign a contract, for both parties' peace of mind. If extras come up, Marius openly discuss them with you before taking any action - my job required quite a few and Marius was also great to stay competitive price-wise whilst keeping the quality of the work sky-high.

Norbert and Raymond delivered a very prompt quotation which was sufficiently detailed for me to make a decision on the work. They were keen and diligent throughout the project, working hard for a very fair price. Their attention to detail was excellent, they didn't skimp on quality and worked tirelessly for 7 continuous days to deliver as promised. I'm very pleased with the end result - a paved terraced garden engineered with drainage channels, brickwork and timbers. I can definitely recommend them for similar work.
