Carpentry- 14 Oct 2025
Mr Williamson did a fantastic job installing and repairing fire doors in my HMO property to the exact standard required by the council. He was very professional, punctual, and highly attentive to detail throughout the entire project. The quality of his work was exceptional, and he ensured the job was completed within the agreed deadline. I’m very pleased with his service and would gladly recommend him to anyone looking for a reliable and skilled carpenter.

What to ask a Soho extension builder before hiring?

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

An extension builder in Soho 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 Soho 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 Soho?

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 Soho 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 Soho 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.
