Groundwork & Foundations- 1 May 2026
Richard and team are absolutely one of a kind! They can do absolutely anything you can think of! It’s the first time I’ve used MyBuilder and to find Lionheart Builders, I’ve hit the jackpot! They completely put my mind at ease, very professional and knowledgeable. The work was completed to a very high standard and not to mention they are very reasonably priced too!! We’re definitely keeping their contact details for all of our future jobs and will recommend them to all our friends and family. Thank you both for such an amazing experience!

What to ask a Mirfield extension builder before hiring?

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

An extension builder in Mirfield 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 Mirfield 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 Mirfield?

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 Mirfield 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 Mirfield 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.
