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.

Tony & Nicola Nugent 7 Bramley Gardens South Oxhey Hertfordshire WD196YD 07892 683 819 Whilst requesting quotations from contractors we came across Martin davies and requested if he could visit and quote us for a single floor extension. As this was a big deal for us financially I needed to make sure I was doing the right thing and ended up getting around 7 quotations from different builders. Martins quote was very competitive and after meeting him we decided to go with him. For us it was a great move especially as we have never done anything like this before. Martin from the start has been great, he kept us up to date all the way through with what the next step is and what are options were whilst giving us ideas from his experience and knowledge, nothing ever seemed to be too much trouble, whether it was myself or my wife asking for additional bits or even rescuing our cat from the house roof ! The team Martin uses are also brilliant, really friendly and genuinely nice guys, Tom the Electrician was brilliant and again nothing was too much trouble. I have quite a few friends who also work in the building trade and all have commented on Martins work that it is done to a high standard, this includes my father who was a builder for over 30 years. I would highly recommend Martin and certainly will be using him in the future for more works, I’m more than happy to be contacted for further information, also happy if you would like to visit and take a look yourself!

Extensions- 30 Dec 2021
Its been a pleasure having Albi and his team build our extenstion. Excellent job done (we had a 32 sq m extension for a new kitchen/dining room and the build was seamless). Good workmanship and genuinely easy to interact with. Albi kept to the timelines, offered good suggestions and delivered excellently. Albi and his team are reliable and provided a competitive fair price. They would be here early (7.30 - 5) 6 days a week and were a genuine pleasure to deal with. They were neat (even covering our drive with mdf panels to protect it from rubble) and then pressure washing it clean at the end. Works included Foundations Construction work Skylights Roof structure and roofing Windows/Bi fold door Exterior render Insulation Woodwork - doors, architraves, skirting Plumbing Electrics Plastering Paint Flooring (wood & tile) Tiling Installing kitchen

Lack of professionalism! Called me at 2150 to say was interested in job, warning signal but said far enough so booked an appointment. He didn’t turn up nor respond to my texts asking if he was held up somewhere. I am not sure how trustworthy he is.

Piotr's work is really good. I did four or five kitchens with him and I did recommend him to him to another builder friend of mine and they are happy with his work - no complaints. He arrived on time so there were no delays. I too am very pleased with his work and would of course use him again when I have some stone work to be done.
