Bricklaying- 9 Dec 2025
We agreed a start date for the work, and from the beginning communication was slow and required constant chasing. Alan sent me a full materials list, which I purchased on the understanding that the job was proceeding. As the start date approached, I repeatedly tried to confirm when he would arrive so I could organise my day and be available to help on site, as we agreed for me to b involved as a labour. Despite reading my messages, he stopped responding entirely. I sent multiple messages and tried calling several times over the course of a week and received no reply at all. The job never started, and I was left with purchased materials and a significant amount of wasted time. I cannot comment on the quality of his work as he never turned up, but based on the communication alone I would strongly advise others to be cautious.

What to ask a Crowborough extension builder before hiring?

Before hiring an extension builder in Crowborough or extension building company in Crowborough, 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 Crowborough?

An extension builder in Crowborough 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 Crowborough 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 Crowborough?

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 Crowborough 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 Crowborough 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.
