Insulation- 2 Mar 2022
Jonny is excellent, a real pleasure to deal with, intelligent and very capable. The work was just as l had hoped, good quality, thpight through, efficiently carried out and reasonably priced. I am only sorry l have not had the chance to met him, as l was never on site. But there will be more work to be done, and l will certainly ask him first. My daughter was on site and was impressed by his thoroughness and extensively researched investigations befote he gave us areport and a quote, all very helpful for me 150 miles away. He understood our aims and was very sympathetic and helpful, and even recommended an EPC assessor to complete the project, which has been a total success.

Extensions- 14 May 2020
I was concerned picking a builder from my builder as this was a large project involving a loft conversion and single story rear extension as part of an entire renovation project. I needn’t have worried, West field contractors have been fantastic. Dimitris and his team have treated the property like it’s their own and the work has been to a very high standard. They have been respectful to our neighbours and have gone above and beyond to make them happy. They have understood our need to keep costs down and have been fair and competitive with their pricing. I have been so glad we hired them and I cannot recommend them enough.

Tom did an excellent job in completing my porch, despite having to work through a back injury. He was always prompt, and kept me informed of work in progress and timescales. He managed the job very well, and ensured that the door and window that were supplied by Price Glass were fitted in tune with the porch build sequence. He kept me informed of any changes to the budget caused by changes that were requested or necessitated by external factors. I would certainly recommend Tom for your project.

Restoration & Refurbishment- 25 Mar 2026
George was communicative and professional from the very start, and understood my vision from the first meeting. He was flexible and worked with me on areas that I wasn't confident with, while providing helpful guidance on how to make my ideas come to life. Throughout the duration of the project George went above and beyond to ensure my family were comfortable, every stage was completed to a high standard and and approached every day with enthusiasm, asking for feedback as we went so he could apply lessons learned to his work going forward. Whether you have a first-project or you're experienced, I would 100% recommend Yolk. I'd been putting my project off due to a previous bad experience, but mine any my family's faith has now been renewed entirely

Landscaping- 13 Nov 2014
We hired SJR Construction to patio a large area of our garden and remove some raised beds and greenhouse base. Steven was a very polite and helpful guy to work with and gace us an affordable quote. His workers battled through very wet conditions to complete the work in reasonable time and we are pleased with the result. We did have a minor misunderstanding involving some finishing touches and rubbish removal but this was sorted out promtly by Steven on the same day. On the whole very nice people who I would recommend to others.
