James was professional from start to finish and did a brilliant job removing an interior structure wall - which ended up being a bit more challenging since we have a concrete house - and stabilised the wall with a steel girder. He offered a competitive price and clearly had a lot of experience. Would highly recommend to anyone needing any work done.

Extensions- 5 Aug 2019
First Class. We wouldn't hesitate to use JD Building and Maintenance again. Jordan and his brother did a brilliant job. We've already asked for a quote for another job and recommended them to work colleagues. They started the job when they said they would and worked long hours to complete the task (early). They kept the site tidy throughout, interpreted and accommodated our changing requirements even when we weren't exactly sure how to achieve what we wanted. We now have a quality kitchen extension of which we can be proud. Thank you Jordan. David & Heather

Fielding & Co fitted a bathroom for me earlier this year. They were very professional, accommodating & their attention to detail was impeccable. I changed my plan half way though and Colin sat down with me & my husband and helped work out our new plan & made it perfect for our family. He was available in the evenings when we had question & even helped come with us when we needed to sort the measurements for the order. We couldn’t recommend they highly enough.

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.
