Latest review:
We needed a small, 5m x 3m extension to the rear of our house to give us more living space on the ground floor. We live in a curved building so this wasn't a straightforward build and we had builders not willing to quote as they couldn't build on a curve. We had several quotes but found Joe's to be very competitive but he also gave us a very detailed breakdown of what would happen and at a what stage and timeframe. Joe delivered on everything. There were a few minor hiccups along the way as you would expect with any build, but everything was dealt with as a priority and nothing was too much trouble. We are more than satisfied with the end result and would highly recommend Joe and his team for any work, big or small, if fact, we have booked him again for some more work later on this year.

Tiling- 11 Dec 2017
Daniel, perfectly laid our shower-room floor, cutting in tiled envelope and angling floor so water drains off. Previous tillers could manage or remember. He also fixed cupboard sliding rails which again previous builder did do properly. He is hard-working, capable and has good attitude towards feedback and finishing off work to acceptable standard.

Latest review:
I think Anthony is best described as he and his staff take pride in their work. I had a new block-paved drive done. All way through he advised me on the best options and ideas I would not have thought of such as ensuring that any rainwater took the best path towards drains rather than merely ending up in the garden. I would thoroughly recommend Hennerleys for work.
