Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Dmitry

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

We are very happy we went with 1Horizon. We wanted to do some of the internal work ourselves and they were the only ones we spoke to who agreed to this. They were happy to work with us on our quote to get what we needed. Aiden and his team were friendly, honest and reliable throughout and the standard of work provided by all trades was excellent. I would have no hesitation in recommending to others.

Dan and his colleague built a rather large red brick wall for me which I am very pleased with. They were fast, tidy and efficient. They were also able to give advise on the best way to finish off the top of the wall. Secondly, they used the right mix of cement and lime to continue with the same colour mortar. They were also able to calculate exactly the quantity of bricks, cement etc. I would need so therefore there was very little wastage. I would definitely use them again.

Hi I’m Joe of JAS Property Maintenance and also JSB Bespoke metal and woodwork. I have recently gone back to working on my own but I have been in the building trade since I was young working with family members then to college to pass my brickwork picked up a lot along the way working with many trades which I find makes me unique as I can come in and do most things you may need. The metal and woodwork side has been the more recent years even though I still did the building and house renovating on weekends but I can make gates, fencing, security bars, fancy art products and much more. Hope to do work for you in the near future Joe

We are happy to quote anything, bespoke is my passion. If you can’t get someone to build it, we can! Please feel free to browse photos of my work, I will try upload a little bit of everything. If you don’t see a photo of a job your asking for, feel free to contact me and I’m sure I will be able to show you examples of my work in that area. Friendly team of lads aging between 18 and 66! We look forward to working with you. P.s as mention above we are new to rated trades and as such have decades of experience, thousands of builds under our belts but alas, no rating on here. Any and all feedback will be most welcome. Stay safe everyone and see you on the job!
