Central Heating- 15 Mar 2022
Very responsive, quick to reply to the post, quick to quote and to take the work on. Ben did a really great job. He was extremely professional, knowledgeable , clean and tidy, even taking all the rubbish away with him. The new radiator looks great, is no longer leaking and my whole central heating system is working the best its worked for some time. I would highly recommend Ben and Rowla Construction Ltd.

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!

Roofing (Flat)- 15 Apr 2016
An honest builder, came an inspected the roof and advised that not the whole roof needed replacing, only the section that was damaged needs to be replaced (other builders who inspected the roof advised the whole roof would have to be replaced) Quote received within 24 hours and once this was accepted gave me a start date. Email received the day before start date that his team will be on site the next morning. Received photos of the roof before and after, very pleased with the job. I will keep his contact details in my diary, will always approach him first for any building work required in the future.

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.
