Bricklaying- 14 Apr 2026
Prior to starting the job, Shefit was very responsive to my emails and WhatsApp messages and was very easy to communicate with. I left Shefit detailed instructions of where to position the walls we wanted constructing for our small extension as I was not going to be there when he arrived. I returned later that afternoon to find the job well under way - he had even sent me a short video of the work in progress - yo find everything had been done as per my instructions. The team worked all day and finished the job in about 8 hours - hardly stopping for a break it seems and refusing any attempt by my wife to ply them with coffee and tea. They left the site clean and tidy were incredibly polite and respectful - one of them even asking if they could use the toilet, which of course they could! I would recommend Shefit and his team wholeheartedly. The price was reasonable and the job was done quickly and cleanly.

Handyman- 11 Feb 2025
Brady & Cesar did an excellent job hanging/painting six internal doors. The door frames weren’t straight, which made the job more challenging, but they took the time to get everything just right. They were meticulous in their work, covering the floor to protect our home and ensuring everything was clean afterward. Both explained what they were doing throughout the process and provided a personable, professional service. Would highly recommend Davis-Brady Construction Limited

Extensions- 3 Oct 2025
Job was to convert WC in outbuilding into a full bathroom, do walls and ceiling in outbuilding to convert into an office space. Price was agreed with things planned, still with some issues towards later part of job, It worked out in the end. Overall I am giving 3-4 stars as quality of work is good. Just need to have things written down with him, and a thorough discussion on plan before commencing work and agree on payment plan. suggested to keep 20% to be paid at completion.

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 experience do you have with similar extensions in Charterhouse?

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