Extensions- 29 Aug 2021
Communicated well at the start with reasonable cost. work was done well but the finishing was not so great as expected. The end cost was very expensive. Charged by the hour, the team were very slow which was upsetting to see me pay for time where they sat around not doing much. Ensure to agree fixed price. Communication after job is poor, double glazing has warranty which now not being able to communicate with kostas having to pay to get things done that should be covered in warranty. Central heating give huge problems. Do not use for big jobs

Kitchen Fitting- 17 Nov 2025
We recently had our kitchen refurbished by Dumitru, and we couldn’t be happier with how everything turned out. He’s one of those rare builders who combines professionalism with real care for the details. He worked efficiently, kept the place tidy throughout the project, and always cleaned up after himself — which honestly made such a difference when living through a renovation. What I appreciated most was how supportive he was when it came to choosing the right materials. He guided us through the options without ever pushing, and his advice proved spot-on. The final result is exactly what we hoped for and more. If you’re looking for someone reliable, skilled, and easy to work with, I totally recommend Dumitru P.S. For anyone curious about the scope of the work: Dumitru changed our worktop, removed the old tiles and redid the flooring with laminate, installed a new cooker and hob, fitted a new sink, repaired the walls after the new boiler went in, and repainted everything. Top work

Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.

Extensions- 15 Jun 2024
My advice is avoid. Poor communication Poor workmanship Poor quality finish Create 'issues' during build to make you pay more than quoted Left project incomplete We pursued through the Court and won the case, but of course he is unable to pay, so we are pursing further through the Court. He will respond to the review with some excuse, but there is absoultley no excuse for poor workmanship and quality. Happy to share pictures and videos on request.

I cannot recommend Marcin and his men more. They were immensely helpful throughout a difficult (due to my inexperience and space and budget constraints) and rushed project. They worked to my budget and schedule and delivered to high quality - really an unbelievable job. If you choose them, you are in good hands. They are honest, reliable, and trustworthy.
