Conversions - General- 5 Feb 2025
Carl discussed our requirements, offered suggestions and provided 3D plans. The quote was very competitive and even included a small utility room which we didn’t expect. Throughout the conversion Carl explained each stage of the process and everyone involved was polite and friendly. The work was carried out to a high standard and this has been commented on by others. We are delighted with our beautiful new kitchen diner. Thank you Carl and the team.

Extensions- 21 Aug 2023
Howard, Martin and team are easy to work with and happy to discuss any questions or queries along the way. We found them to be friendly and professional at all times and they made building work being completed whilst living in the house with children extremely easy! Very neat and tidy as they completed the project. They’ve done an amazing job. At the end of completion , any small snags were completed quickly. Definitely recommend them and would use them again.

Groundwork & Foundations- 28 Nov 2025
I needed a 1.5ft deep and1 1ft wide French drain installed around the perimeter of my house to prevent bridging of the damp proof course. Karl has been absolutely amazing throughout, from the first contact where he was very responsive and described exactly what the work would consist of. When the work was done, Karl sent me photos (I live far away from where the work was being down) and a video, and the work was done to an incredibly high standard. I would highly recommend Karl, and he will now be my go-to person for any groundwork jobs that I have in the future.

What to ask a Manchester extension builder before hiring?

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

An extension builder in Manchester 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 Manchester 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 Manchester?

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 Manchester 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 Manchester 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.
