Fedor and his team are polite, hard-working and extremely talented. It was a complicated job and Fedor handled it brilliantly. We are absolutely delighted with the beautiful London Stock brick wall that has been built. We would definitely recommend Fedor and Cuicut Construction, and will certainly use them again in the future.

We have had our boiler replaced recently replaced by Nigel at Beaumont Plumbing. Excellent service and very professional. Would recommend to everyone. We have had issues with our heating and radiators since we moved in 6 months ago but no one was able to fix. Very reasonable price. Since fitting us with a new boiler Nigel has kindly organised our roof to be repaired. The guys were so lovely and professional. I now have a sealed roof and warm house thanks to them. Definitely will 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.
