Windows & Doors (Wooden)- 4 Dec 2024
After giving me a good quote on some work replacing a rotten windowsill, Albert came two days later to do the work. He arrived on time (early in fact!), took care to cover the furniture, was polite, professional, knowledgeable, and got the job done quickly and efficiently, keeping me informed all the way, and cleaning up afterwards. I was really impressed with both the job and Albert, and will definitely be booking him again in the future!

Loft Conversion- 14 Oct 2021
Zilvinas produced drawings promptly and at a very competitive rate. He attended several site visits and ensured to incorporate all of our ideas. We have received fantastic after sales service from GoldBerg Engineering throughout the project and would not have had the results we have, without Zilvinas. Goldberg Engineering has provided brilliant guidance throughout, through rapid response emailing, regular Skype and several site visits.

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

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.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Kitchen Fitting- 8 Nov 2017
After a cowboy builder failed to install our kitchen Tomaz came to the rescue. He gave us a very fair price as he knew we had lost out money already having to replace broken or damaged parts of the kitchen. He communicates very well through the build and always called me on FaceTime to show me things he was doing in the kitchen and to ask for my preferences. If anyone needs a kitchen fitter with minimal hassle use Tomaz. The job was completed in a week, which included tiling . He fitted a howdens kitchen from scratch And it looks very tidy. Thanks Tomaz, next job loft extension !
