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.

CAD / Drawings- 23 Sep 2020
Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.

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.

Conversions - General- 19 Feb 2026
Hammer de silva provided a garage conversion quote and literally contacted every day saying he needed the job. After getting the job , I told him we need to go through building control to make sure everything is done in properly. There was about 2- 3 week delay because of building control . This guy keep taking multiple jobs and it’s more than one year and he’s still not finished with the job. He’s only done half of the job and keep coming up with excuses, he told us his wife being severely ill, his daughter being pregnant and needed help with delivery, other financial problems and endless excuses. In between he increased the price of job and took more money from us. He takes money spends it and doesn’t come back to work saying he doesn’t have money and need to find another job as well. Because of his careless work, I couldn’t use my utility room, decking area properly for over a year now costing so much stress and grief, might have to seek legal action if not finished in 2,3 weeks
