Bathroom Fitting- 7 Dec 2012
Absolutely delighted with both the professionalism of Shaun and his team and of course the finish of the job. Special thanks to Sam, who did all the hard work. The job was completed to agreed timeframe and budget, so no worries on that front, and they kept our home both clean and tidy - always important. I would have no hesitation in using Shaun and his team again, and no hesitation whatsoever in recommending to friends and family. Thank you very much.

Latest review:
Barrie and his team recently renovated the downstairs to our house. This involved knocking down 2 structural walls, re locating a kitchen and living room, inserting large bifold doors, a kitchen, a utility room and re tiling the floor. We found them to be very hard working, trustworthy and reliable. They were easy to communicate with and happily stopped to talk through any concerns and to update us on the progress of the build. We have 2 dogs and remained living in the house during the work- both which they worked around. We would thoroughly recommend Barrie and would use him again should we get any more work done to the house.

Extensions- 10 Dec 2022
We highly recommend David. The work to replace our garage door, with window and wall, has exceeded our expectations, looks as if it has always been there! The care he took to match the bricks and get the right style window to match the rest of the bungalow was excellent, even to the painiting of the walls to match the original interior. He consulted us every step of the way and advised us the best possible way to acheive the best outcome. Always arrived when he said he was coming and kept us informed every day of what would be done the next day. If we have any other projects in the future , we will definately ask David first.

What to ask a Berkeley extension builder before hiring?

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

An extension builder in Berkeley 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 Berkeley 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 Berkeley?

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 Berkeley 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 Berkeley 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.
