Bathroom Fitting- 17 Feb 2025
From start to finish the team was superb. Josh was helpful in suggesting ideas to make the most of the job. Bradley, Ray and Dave were all expert in their work and the job progressed quickly. Josh was excellent in communicating with us to advise who would be arriving the next day. As older clients we appreciated workers with whom we felt comfortable. The whole process gave us an ensuite to be proud of. Expert workmanship and a very pleasing finish. Would not hesitate to employ this contractor again.

Decking- 31 May 2024
Firstly they came on time and job was finished on time, I would have given 4 1/2 stars overall. There was a couple of things I would have given 4 1/2 stars for and a mostly I would have given 5 stars. They was always on time every morning and was nice and polite. Overall I'm satisfied and looking forward to completing the rest myself. I had so many nice builders come to look and price the work, it was hard to choose. I am very happy with the outcome of the work.

My partner and I are so pleased with the extension work which Paul & team carried out, not just what was done but also the way it was done. All of the team were great - they turned up when they said they would, and simply got on with their work, They were all polite, friendly, helpful, conscientious, and made several suggestions to improve the finished work.

What experience do you have with similar extensions in Coryton?

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