Extensions- 11 May 2022
Craig has recently completed a garage to kitchen extension with an added downstairs toilet and utility room. The whole process has been positive, Craig was confident in his quote and advise but was keen to listen to our ideas and was happy to discuss various options around budget and function etc. Craig's initial quote was agreed and didn't differ, although I appreciate building materials may have increased during completion, which made the whole project manageable and we weren't worried about hidden charges etc. I would highly recommend Craig and he also has great contacts within the industry for electrical, plumbing, roofing and windows / doors to ensure all jobs are completed to standard.

What to ask a Doncaster extension builder before hiring?

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

An extension builder in Doncaster 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 Doncaster 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 Doncaster?

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 Doncaster 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 Doncaster 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.
