Extensions- 17 Aug 2024
Amazing 5* work! Highly recommend James and team. We had a kitchen ground floor extension completed last year; it has exceeded our expectations. James followed up all issues and questions in a professional manner. Jimmy fitted the flooring throughout the ground floor - perfect. Despite the appalling weather the work was completed on time. The extension is also built to such a high standard it weathered the Stalybridge tornado in December!!! Photos to follow 😊 we can’t thank you enough James!

Restoration & Refurbishment- 9 Apr 2023
Gavin did a really good job of fitting the kitchen and I was really pleased with his work. There was an issue with the initial plumber but again, this was sorted very quickly and he got a new guy on the job quickly. I would hire him again if I was going to do another kitchen.

Extensions- 14 May 2019
We engaged Civenco following a three way quote in which they were clearly competitive. What impressed us most was the professionalism and approachability of John and his team. When it came to the job itself they were timely, very competent and helpful throughout. They rectified minor snags quickly and were a pleasure to work with. I have no hesitation in recommending them.

Bricklaying- 23 Mar 2022
We hired Patryk and Darek at Beelosophy to replace our wooden garden fence with a brick wall and help us re-design our garden. We were very impressed with both their skills and their experience within the industry. It seems like there is nothing they can't do. Their project management and planning skills are great and something a lot of other builders, who we worked with in the past, definitely lacked. They were punctual and always kept us informed about the stages of the project. If plans needed to change due to weather conditions or unforeseen circumstances, such as supplier delays, Patryk and Darek were quick to work out a new plan so the project wouldn't have to stop. Throughout the project they were very resourceful and mindful on minimising the waste of materials. When we presented them with the ideas for our garden design they worked with us to come up with the best solution to pull everything together, so we would end up exactly with what we had envisaged. The accuracy they delivered the work with is second to none. I have never worked with anyone who takes so much pride in their work and it was certainly noticed by everyone. Having had multiple quotes from other builders for this project, Beelosophy has been very competitive. We are so pleased to have found them and they are our go-to guys now for any projects we have planned. We have already recommended them lots of people and we are looking forward to be working with them again.

Extensions- 15 Aug 2018
Billy did a fantastic job on the renovation of our house. Both myself and my husband were completely inexperienced in renovations, but Billy always made us feel well informed and I immediately felt like we could trust both him and the rest of his team, which is an incredibly important thing when you have people in your house all day for months. The end result of the house looked fantastic, would definitely invite Billy back when we need more work doing. He wasn't just good at the building work, but also gave us some really good advice and helped us communicate with other professionals on the build, such as the structural engineer.
