Bricklaying- 22 Oct 2023
I chose this trader because he was local and responded quickly and politely to my enquiry . He was also able to provide a detailed quote listing all materials and labour charges and the final bill was exactly as agreed. The job started on the day agreed and finished on time, the end result was high quality and I could not have expected better. A team who worked tidily and were thorough in clearing up. Very positively recommended, I would use them again without hesitation.

Extensions- 15 Jun 2026
We hired Mac to complete a single storey extension which involved digging foundations, removing internal walls and installing a number of RSJs. Mac completed all of the work ahead of the tight schedule that we asked for as we had our first baby in the way. His workmanship was high quality throughout the project, he was dedicated and did not have multiple jobs on the go at once unlike other builders. we couldn’t be happier with the result and would hire Mac again for any future work. Mac was very friendly and approachable through the project and always had time to listen to our requests and even gave me some tips on other DIY projected had going simultaneously! I have no negative words to say about him.

What experience do you have with similar extensions in West Sussex?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Sussex extension builder’s ability to deliver a result that meets your expectations.
