What Our Extension Clients Say
We recently chose Nelhams & Sons to build a single-story extension on our home, and we honestly couldn’t be happier with the process or the finished result. The new extension feels solid, stylish, and perfectly integrated with our existing home.
Jack, Robert and Dave, just completed our driveway which was finished to an incredibly high standard and their attention to detail is 2nd to none. The project was started exactly when they said and completed slightly ahead of schedule!
Most trustworthy decent builders I’ve come across, did so much extra work for no extra cost. Couldn’t recommend enough.
