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...

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.

Plastering- 8 Jun 2026
We were thoroughly pleased with Bathroom Renovation, Bahram and the services provided. We required stud walls throughout our apartment, ceiling replacement and ducting/pipework concealing. I can only say that Bahram and his communications have been a breath of fresh air. The team are efficient, friendly and get the job done - most importantly Bahram takes pride in the work his team complete. Our job was relatively urgent and Bahram offered what I feel was a fair price, remained communicative and had his team readily available to get the job completed within the timeframe. Most importantly, as with it seems all building works, jobs can grow slightly, but Bahram’s considered approach and advice was invaluable. We increased the scope of our works mid-job, and are really pleased with the results. Fair pricing, someone who has pride in their work, and a job well done.

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.
