CJ was excellent from start to finish. He’s reliable, punctual, and a true one-man band who took care of everything himself. He fully embraced our bold design and helped bring it to life with great attention to detail.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

What qualifications and experience do you have as an extension builder in Whitechapel?

What experience do you have with similar extensions in Whitechapel?

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 Whitechapel extension builder’s ability to deliver a result that meets your expectations.
