Restoration & Refurbishment- 19 Nov 2019
Iljaz and his Team were brilliant! I was slightly concerned having no reviews. They found the leak, fixed it and patched up the wall in very tidy and professional manner. He did say he wouldn't be able to come today and updated me, however he made time to come in-between his day to sort out my issue. Not many true trades people like this and very honest and stuck to his word. I would definitely recommend him and would not hesitate to use his team again. Thank Iljaz!

Bricklaying- 17 Jun 2022
Our brick garden wall was collapsing and I contacted Richard Fitzgerald for a quotation. I'd already had a few quotes from other builders, some of whom had told me I needed work doing that didn't need doing! I found Richard to be trustworthy. He provided a competitive quote. He managed to source bricks that matched the colour of the adjoining wall, gave us a detailed breakdown of the work he would do, and didn't ask for any payment in advance. He built a strong brick wall with a concrete support wall behind. The finished wall is excellent and we are very happy with the work he and his team have done. On finishing the work the premises were left clean and tidy. I am very happy to recommend him.

New extension, kitchen, shower room, flooring, fiber glass roof, roof light, new electrics, plumbing, boiler installation, removal of chimney, rear patio, soakaway, painting and decorating Satnam has exceeded our expectations in carrying out the complete job to our satisfaction within the agreed time to a very high standard. We are extremely pleased with his work. Satnam helped us select good quality products from suppliers for much less cost than if we were to source them ourselves. He was honest, courteous, professional, flexible, open to changes and made suggestions to improve the overall look. He even passed on his builders' discounts to us. We highly recommend this ambitious young builder who has excelled in the trade. We wish Satnam and his team the very best.

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!

Extensions- 30 Jan 2023
I had the pleasure of having them carry out a single story extension and fibreglass new roof of my property. I found they always turned up when specified and carried out fantastic quality work for a competitive price. Not being a builder you have to place trust in a person / company. They always made sure that we were happy keeping us updated with the project every step of the way. They were kind and considerate to our neighbours making sure they were not loud early in the morning or late in the evenings making the whole process run smoothly. I can not stress enough how great these guys are. Thanks
