Extensions- 5 May 2026
Really happy with the outcome of the double storey extension and the work Daniel completed. Of course like any major project, issues and niggles cropped up, but very happy with the way things were always resolved. Timeline was stretched but is very often the case with building work. I thought Dan communicated really well with me without me chasing him and would always reply almost immediately when I reached out to him. My only criticism if there was one would be that the tradesmen he used didn't always keep site particularly tidy, however this was rectified when asked. I would certainly use Dan again and have happily recommended him to friends, and his costings were very reasonable and were kept to exactly. I would be happy show anyone around to see his work.

I recently had an extension and renovation completed by Snowball Invest, and I couldn’t be happier with the results! From start to finish, their team was professional, reliable, and highly skilled. They listened carefully to my vision, offered valuable suggestions, and kept me informed at every stage of the project. The quality of their workmanship is outstanding, with attention to detail that truly transformed my home. The project was completed on time and within budget, despite a few unexpected challenges that they handled with ease.

What to ask a Derby extension builder before hiring?

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

An extension builder in Derby 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 Derby 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 Derby?

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 Derby 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 Derby 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.
