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!

Kitchen Fitting- 8 Oct 2018
Had three quotes to fit new Wrens kitchen,and picked Stanley even though his quote was not the cheapest.He just seemed a nice guy,and he is.The work was carried out quickly and cleanly,arriving about 08.15 finishing about 17.00.A few minor things need to be carried out mainly due to wrens not delivering all trim but have been told will return as soon as it arrives. I would not hesitate to use Stanley again.Will update when complete.

What experience do you have with similar extensions in Colney Hatch?

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