Kitchen Fitting- 18 Nov 2025
Original timeline stretched a bit due to his other jobs but this was fine. Mario started work early and finished early which suited us. He came to visit and we agreed a price at the start and he stuck to it even when he realised some additional plumbing would be needed. He was honest about some accidental damage. Attention to detail is good and he has all the kit. I would have given 5 stars- he's a proper professional and I enjoyed working with him. 3 stars only because as soon as the work was done he became incommunicado (I messaged a week later to ask how to lift door which had dropped down a few mm on fridge). The warranty advertised is one of the reasons I went with MGB which was £200 more expensive than contenders so this was disappointing. I would have asked him to do my parents' new kitchen too otherwise.

Corinth Contractors from the beginning was a delight to work with upon our project. Some issues arose through the works as it was a fairly large project but quick solutions were presented! The service and quality of work was great and their project programme really helped us keep track throughout especially when we needed to supply items! Very happy with the final product and we have recommended to friends and family when/if they do their houses in the future.

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.
