David worked on my property for just over 6 months. Structurally I had a supporting wall removed and ground floor extension. David competed a complete refurbishment on my house which is a 3 bedroom Victorian property. He worked with additional contractors and project managed the entire thing from start to finish. He was a pleasure to deal with and I felt he gave my property the same care and attention to detail he would have given his own home. I happily recommend David to my friends and family.

What to ask a Winchester extension builder before hiring?

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

An extension builder in Winchester 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 Winchester 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 Winchester?

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 Winchester 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 Winchester 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.
