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.

I cannot recommend Grigore and his team highly enough. After a long-term tenant left my property in a terrible state, I urgently needed a builder who could work quickly and efficiently to bring the house back up to a high standard and minimize void periods. Grigore provided a fantastic quote and started the job within a day. The results were nothing short of exceptional. Even the estate agents who came to value the property were thoroughly impressed, and I’ve since received multiple offers. Thank you!!

A great company to deal with, prompt, reliable and very professional. We live in an old Victorian house with hardly a straight angle anywhere. So Anunas had a tricky job to do. The job was done perfectly and to agreed cost. I would recommend this builder to you. If I could could give give 6 stars I would. Great job well done.
