Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

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.
