What Our Customers Say
I used National Association of Building Contractors to find a builder to build my extension and cannot speak highly enough of them both professional and personable and could not be happier. The extension to look as good as it does! It’s refreshing to see a company not focusing purely on profit or costs.
A great experience start-to-finish! Paul, Sarah and the team were an absolute pleasure. The job felt well-organised and the builders clearly runs a tight ship as everything ran on schedule. We’re so pleased with the quality of the work and the results. In fact, when Building Control came to sign off the work, the inspector commented that the work was done to a really high standard. Can’t get better than that!
I used a builder Dunn and Michaels from South London to complete our extension. I am completely satisfied with the job carried out. The process was faultless from start to finish. Professional in all aspects of the job. I would highly recommend NABC to anyone.
