Hard Flooring- 22 Oct 2025
Enea did an incredible job, and we’re beyond happy with the final result. He was very accommodating, helped us choose the right tone of varnish beforehand, and kept us updated throughout the day by sending pictures of his progress (as we were both at work). Enea is trustworthy, and even though we didn’t have the chance to meet him in person, he left the flat securely, taking care of our keys and door. We highly recommend Enea!

What experience do you have with similar extensions in Clapham Common?

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