Extensions- 23 Feb 2025
I am extremely pleased with the job has done for me. The work was absolutely spot-on, and nothing was too much trouble for them. They went above and beyond to ensure everything was completed to the highest standard and, most importantly, made sure my house was safe throughout the installation process. What really stood out was how much they looked after me—not just in terms of the work itself, but also by helping me keep costs down wherever possible. They even found a smart and efficient way to lift and install the beams, despite the uneven surface and the bricks being spread all around. Their problem-solving skills and commitment to getting the job done right were truly impressive. A special mention to Sandu—he was simply unbelievable! His expertise, dedication, and attention to detail were outstanding. I couldn’t be happier with the job, and I highly recommend this company to anyone needing RSJ installation.

Conservatories- 14 Jun 2026
Wow, Xavia and his crew have done an amazing job replacing old polycarbonate conservatory roof with a solid tiled, insulated warm roof. I couldn't recommend these people enough, clean, curious, and experts in my opinion at all that they do. They went over and above when the weather changed to unforeseen heavy rain, and made sure we were watertight throughout. Lovely people, wonderful job, the best tradesmen I've met on my 64 years on this planet. Thank you.
