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.

Fielding & Co fitted a bathroom for me earlier this year. They were very professional, accommodating & their attention to detail was impeccable. I changed my plan half way though and Colin sat down with me & my husband and helped work out our new plan & made it perfect for our family. He was available in the evenings when we had question & even helped come with us when we needed to sort the measurements for the order. We couldn’t recommend they highly enough.

Extensions- 16 May 2024
Did some great work initially - particularly Gordy - but too argumentative and slow around matters arising within warranty. Refused to deal with a leak to the Store Room, rushed / made errors in the installation of downspouts and didn’t level our garden as per our contract. Mick was the builder / built the store room to the side of the extension. Not sure what he means (below) by ‘fell out with the builder’ - seems to be talking about himself in the third person here… Took forever to have the flooring (Indian Store) issues resolved, but did the right thing eventually. As ever, all very convoluted and over stressful with Mick. A good builder, just needs to argue less and resolve things that aren’t up to scratch.

Latest review:
James was professional from start to finish and did a brilliant job removing an interior structure wall - which ended up being a bit more challenging since we have a concrete house - and stabilised the wall with a steel girder. He offered a competitive price and clearly had a lot of experience. Would highly recommend to anyone needing any work done.
