These guys are a hidden gem. So glad I came across them. They converted an ensuite bathroom into a standalone room. They squeezed me in at short notice, didn't upsell, and explained every step of the work. Finishing was excellent - they go that extra bit to make the job perfect. Whole team are great and work hard - thanks Paul, Martin, Marcin, Rob, Lukas and the rest. We plan to do some more work with them if possible.

James managed our kitchen extension project and took ownership of all carpentry, and we couldn’t have been happier with the outcome. The project was delivered smoothly and to a high standard, and James was a pleasure to have working at our home. We especially loved the outdoor pergola / cinema area and hot tub decking he built too, which was technically quite challenging and looks absolutely fantastic. I would absolutely recommend Linear Carpentry to friends - and have done!

Restoration & Refurbishment- 20 Oct 2022
I contacted Korab to remove my chimney breast, he came to have a look, quoted me for the job and then started the work. Once the work was completed I was over the moon with the work that Korab and his team had done and the service they provided and I asked them to have a new full refurbished house (new electrical work, new plumbing, new plasterboards, new skimming, new doors, new laminate flooring, new tiles, new skirting boards,new bathroom), side extension (which korab helped me to design)and garden patio and a new front garden wall. Korab was a very friendly and easy-going person from the moment I met him in regards to my first project (the chimney breast). He would pay attention to every detail and always ask if I was happy with the work which was being carried out. Korab and his team would always ensure that the work space was left clean. Korab and his team were more than happy to have an input and make suggestions when I needed them too, he also make me feel comfortable to ask any question. Korab and his team did an amazing job in my house and completed the work to a high standard in which I was so happy about. They truly are an experienced group of guys and I would highly recommend them to anyone. What a pleasure it was to have met them. Thankyou once again!

Joinery & Cabinet Making- 28 Oct 2022
Rafal was very helpful, and came up with alternative solutions to the job too from what I'd first suggested. He was prompt, cleaned up each day, and did a really good job which I'm very happy with. It was slightly worrying not to get a confirmed price for the work beforehand, just an estimate, but it turned out that was because it was hard to tell the time the job would take, and in the end what he did charge produced a really good result. I'd highly recommend him.
