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!

Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Denis did a good job plastering and retiling a small area of my kitchen. He responded to my ad promtly, came round the next day to quote and carried out the work 2 days later as requested. He was professional, polite and left my kitchen clean and tidy after the work was done. I'm happy to recommend him and would contact him again if needs be.

What to ask a Shefford extension builder before hiring?

Before hiring an extension builder in Shefford or extension building company in Shefford, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Shefford?

An extension builder in Shefford should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Shefford extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Shefford?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Shefford extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
