Loft Conversion- 20 Jan 2026
I have chosen Byron and his company to complete my loft conversion. Job was completed within given time frame. Byron and the team were polite and hard working. During the building time, any issues found by myself were addressed and rectified as much as possible. At the closing weeks of my project, I have asked Byron to complete additional carpentry tasks. He found the time to accommodate my requests. Job had some messy stages but Byron was always trying to leave site clean as much as it was reasonably possible. Thank you for your work and I would be happy to hire you again in the future.

Latest review:
I was planning an extension to my kitchen, which included a complete refurbishment and the addition of a shower room. I also needed somebody to coordinate all aspects of the project, including recruiting the right resources for the building work, electrics etc. I was extremely pleased that Bull & Chisel were recommended to me. From the start, Bryan and Warren gave me the confidence that they were able to complete the project to my satisfaction. They were happy to continue working with me throughout and they liaised effectively with partners they brought in at key stages to ensure that each task was completed to my satisfaction. As for their own work, I cannot fault them. There are always unexpected challenges that arise in these types of project. Bryan & Warren consider these very carefully before providing a solution. They pay close attention to detail and that has resulted for me in a super new space. I highly recommend Bull & Chisel and have already asked them to sign up for more projects in the near future!

Conversions - General- 4 Feb 2021
Johnny (Ionut) was the first person to send me a message as soon as I posted and came over a couple of hours later. He measured up and we told him what we needed. He was able to start work the following week and it only took him a week and few days to convert our garage into an office, gym and loft all done for a reasonable price too. He went above and beyond and nothing was ever too much. I would not hesitate to use Johnny again and have since recommended to him to a lot of friends and family.

Conversions - General- 17 Jul 2024
Job completed on time and to budget, some errors made on the job, lights fitted in wrong place, doorways requiring re-doing as not square for door install. These were all remedied though without pushback. There was a miss on the estimate which has resulted in us having to pay separately for the completion of coving install and very high estimates for optional change request works (fitting laminate flooring) that resulted in us bringing in other companies to do that work. Team were very friendly, place was kept really tidy throughout the work and comms were good.
