Bricklaying- 28 Feb 2016
After receiving a quick and competitive quote from James Walker in response to my advert on My Builder for a garden wall I appointed James to the job which was completed quickly and to a truly excellent standard. It is clear that James and his colleague are both highly skilled and professional. They were happy to answer all my queries and a pleasure to deal with. I would not hesitate in recommending them, they even cleared up after themselves. Very happy customer indeed, many thanks again guys. Best wishes, Billy

What to ask a Bolton extension builder before hiring?

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

An extension builder in Bolton 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 Bolton 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 Bolton?

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 Bolton 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 Bolton 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.
