Ed and Shaun came the other week to re-plaster our kitchen as we were in the middle of having a new one, block off the pantry door and open up what was the pantry, under the stairs into the hallway, thus creating a small but very nice open area for storage. This also allowed us to have more room back in the kitchen. They had a high attention to detail with everything they did and took pride in their work. Would recommend them.

Extensions- 12 Jun 2026
highly recommend Acl brickwork for any major building work. They recently completed a double extension and a full driveway replacement for us. From the initial quote to the final handover, Ashley and his team were fantastic to deal with. The brickwork on the extension matches our original house perfectly, and the finish inside is flawless. The new driveway looks incredibly sharp and has massive curb appeal. Major construction can be stressful, but they kept the site tidy, stuck to the agreed timeline, and were polite and respectful of our neighbours. A huge thank you to the whole team for a job well done!

Ali and his team took on a difficult job converting my outbuilding with no floors, walls or electrics into a lovely en-suite bathroom. They were extremely helpful, worked long hours at short notice and did everything from building work to carpentry, electrics, tiling and plumbing. The team also fitted a kitchenette, painted the walls and removed the rubbish. It was a huge relief to be able to get someone in to do the entire project and at a decent price too. Highly recommend.
