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.

Extensions- 8 Nov 2019
Robert & Bobby did a great job for us! They've been honest, precise and patient. When we had unexpected situations on site they helped us to solve them professionally and in good time. They went the extra mile when we had a need, they were able to advise us and help us with our decisions as well. I lived in the house while they were working and they have always been careful in minimizing all the disruptions for myself and for my family. The extension that they built for us looks beautiful! I would definitely recommend them to others and personally I will try to work with them again in the future whenever I'll have a need. Thank you guys!

What to ask a Sidcup extension builder before hiring?

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

An extension builder in Sidcup 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 Sidcup 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 Sidcup?

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 Sidcup 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 Sidcup 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
