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.

Quality and efficiency of work very good. Once Leigh arrived on site each day he got down to the work immediately and worked hard for the duration of the day. We would certainly hire Leigh again if and when we require more to be done. Definitely recommend Leigh to others.

What to ask a Chislehurst extension builder before hiring?

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

An extension builder in Chislehurst 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 Chislehurst 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 Chislehurst?

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 Chislehurst 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 Chislehurst 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.
