Groundwork & Foundations- 20 Nov 2024
Post completion of the job, there has been an issue with the concrete in that it has crumbled and broken up. Despite multiple emails and the promise this will be rectified it hasn’t been and my last few emails have been ignored. The warranty for the work is clearly worthless which is a concern to me should there be issues with the drainage in the future. If the company would like to get in touch and rectify the issue I’ll amend my feedback.

Extensions- 15 Jul 2019
Very pleased with the kitchen/diner extension John and Shaun built for us. The work was completed to a very high standard, they ensured everything ran smoothly and we finished on schedule. Their many years of experience in the trade was really apparent from the off and this knowledge continued throughout the whole project. They were always friendly and approachable with us and our neighbours, and considerate with our home. We will happily use them again and have recommended them to family and friends. Everyone who has visited so far has been impressed with the build and the finish.

I am a bricklayer by trade but do general building. I have built a few houses from scratch and completed a few barn conversions. Lots of extensions but no job is to small. I have some good sub contactors who do the work I can't. Friendly and reliable. I only do one job at a time start finish then onto next one. The summer house you see in my projects with the decking was built by myself from scratch all of it except the electrics. The fence was just a small quick job to keep the customers new puppy in. I have added some more projects from the last year. I have lots of photos of projects during development but can only upload so many here.

What to ask a Southwell extension builder before hiring?

What qualifications and experience do you have as an extension builder in Southwell?

An extension builder in Southwell 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 Southwell 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 Southwell?

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 Southwell 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 Southwell 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.
