Our back garden wall gate surround was falling apart and the lintel was splitting so we needed someone to rebuild the surround and set things right. Kyle has been brilliant. He was the only one we contacted that wanted to come and see the job in person to provide a quote. He was clear about what would be required and timescale, his quote was competitive and he was fully transparent about the possible additional costs once the work began as there may have been other issues going unseen underneath. He arrived on the agree date and cracked on. The work took about a week as promised and the finish is perfect, and we are so pleased! Wouldn't hesitate to have him back to do further work and would highly recommend. Thanks Kyle!

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!

Conversions - General- 7 Feb 2025
Stephen and his Team were utterly professional, their work was faultless and we couldn't be happy with the job. We had a wall removed in the kitchen which needed a support putting in, and a wall removed in the bathroom and a doorway sealed up. Right from my initial contact with Stephen we got got a good feeling, his quote was the most competitive but we had already decided to go with Stephen anyway as his experience, expertise and integrity were obvious as talked us through the job and what would be required. Their work was fast and to a great standard. We were very impressed with how clean Stephen and his Team managed to keep the house throughout all the work (especially as we have black mortar in the walls), they cleaned up throughly every evening and it made life so much easier on us.

Extensions- 27 Jul 2018
CAL provided a competitive quote and completed the work quickly and to schedule. Additional works pushed the cost over budget but these were detailed in the invoicing. Messy at times but generally a punctual and professional service, able to recommend and worth including in your search for contractors.

Handyman- 14 Jul 2018
Would not recommend. Grouping poor & cracking, tiles not flush causing build up of grime. Cases not fixed properly. Chipped window sill. Flooring starting to move. Didn't want to leave feedback but 2 years on and we are having to have things replaced. Don't want to ask them back as getting them to replace our bath they broke was drama enough. A lot of money spent on this project we'd of never expected to have to touch it for years. Very disappointing
