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.

PrimeCraft Surface Solutions is a London contractor working in surfaces and finishes: bathrooms and wet rooms, kitchens, tiling and stone, timber and tiled floors, fitted joinery, plastering and internal decorating. Most of what we take on is a whole room or a whole property, carried from strip-out to final finish. A bathroom stripped back and rebuilt with tanked wet zones and brassware set level. A kitchen designed, fitted and templated for stone. Wardrobes and media walls made to a drawing and installed. Floors screeded, laid and sanded. Walls skimmed, corniced and painted. Our own teams carry out the work under one point of contact, so you are not left coordinating separate trades around each other. On pricing: we survey and measure first, then issue a written quotation with every element costed separately, so the value of each part of the job is visible before anything is lifted. On site we protect floors and access routes, clear up at the end of each day, and sign the work off room by room. PRIMECRAFT SURFACE SOLUTIONS LTD is registered in England and Wales, with its registered office on Great Portland Street in London. We hold 5 million pounds employers' liability cover and 1 million pounds public liability cover. Surveys and quotations are free and carry no obligation.

Nicolae was punctual, knowledgable and tidy! He tried to identify a leak (turns out the problem may be the washing machine rather than a problem with pipes). He helped rectify the washing machine. He tidied up after himself. Cannot fault him. I have already asked him to return to do other works in my home.

Really pleased with the work that these guys did. They completed my floor-to-ceiling wall unit for my TV, soundbar, fireplace, push-to-open-door shelves and added a side unit with 2 open shelves in a day and a half! They were engaging throughout as we went through numerous design decisions. Would definitely recommend. Thanks guys!
