Groundwork & Foundations- 7 Jun 2026
I got KDM in to install a 75sqm concrete base and was very impressed with them for a number of reasons. - Firstly, their work was excellent. The finish of the base was excellent and they put a lot of effort in to get things perfect. - They were reliable. They showed up when they said they would both for estimates and to actually do the work. Sadly I cannot understate how rare this is today when working with contractors. Communication was excellent. - They're very honest. They gave me a quote based on my requirements which was a little high but manageable. At the end they came in under budget and gave me back the difference. All in all I would be very happy to both have KDM back for more work or to recommend them to anyone else.

What to ask a Haddington extension builder before hiring?

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

An extension builder in Haddington 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 Haddington 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 Haddington?

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 Haddington extension builder’s ability to deliver a result that meets your expectations.
