Good tradesperson! Iounut completed the entire flat and painted it to a very good standard..clean edges, attention to detail etc. He arrived punctually and worked efficiently without cutting corners, and the job was done within schedule. Also he stayed exactly within our agreed budget with no hidden costs and re-selling. The flat now looks transformed and I'm quite impressed. Professional, helpful, and skilled. I would definitely hire Iounut again, and not hesitate to recommend him to friends and family.

Alex did an excellent job removing an old radiator and installing a new vertical radiator in a slightly different position on the wall. He was very diligent, the work to do the pipe chasing got quite dusty, but he kept everything very clean and in good order. Would definitely recommend and use again if I need to

Dan did an amazing job installing and removing a washing machine at my second floor flat in Crouch End. He did such an excellent job, provided new fittings for old ones that had perished, single handedly carried the old machine down the stairs?! and completed all works quickly, carefully and for the lowest quote. He’s a really good guy and I’ll definitely be using him again, I highly recommend him. Thanks again Dan.
