Singh and his colleague did a very good job in packing my loads. They were very gentle and kind. They offloaded everything carefully and assisted in taking heavy loads into the house. Their quote was very cheap and reasonable compared to other movers who charge per item. I will definitely use them again if I need to move things.

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

An extension builder in Swanley 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?

What experience do you have with similar extensions in Swanley?

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