Painting & Decorating- 27 May 2026
Kamil and his colleague were brilliant and I’d highly recommend them. We had a ceiling crack that was bowing, Kamil correctly identified the issue and fixed it. He also sanded and primed our ceiling and walls, ready for us to paint. Kamil & his colleague worked really hard to finish the job in just two days and were polite and tidy. He was clear and considerate about the costs.

FANTASTIC service, will definitely use Lucian and his team again. They were quick to respond, quoted straight away, could start quickly and did a fantastic job. We totally trusted the team, they were respectful with our house and after discussing the final snag list with us they left everything immaculate. We have many other refurbishment jobs to do to our house and will use this team again. Hard-working, polite, super responsive and they have left a really quality finish. We are delighted.

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Conversions - General- 3 Sep 2025
Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

Bathroom Fitting- 22 Sep 2025
I recently had my bathroom completely renovated by Zsolt and Mario and the experience was outstanding from start to finish. They were professional, punctual, and incredibly skilled—nothing was too much trouble, and their attention to detail was second to none. One of the highlights of the project was the walk-in shower they installed, It’s beautifully tiled, and gives the bathroom a sleek, modern feel. They kept the workspace clean, communicated clearly throughout. Zsolt clearly take pride in their work, and it shows in the final result. The bathroom looks fantastic and feels like a real upgrade to the home. I wouldn’t hesitate to recommend them to anyone looking for trustworthy, high-quality builders. Thanks again, Zsolt and the rest of the team, you’ve done a brilliant job.
