To say Andy and his team did an amazing job is an understatement! Every step of the process was above and beyond, to coming round to give a quote, to the tidy up at the end. Outstanding attitude and communication, very prompt and tidy and the workmanship is perfect! I really couldn't be happier with my knock through and especially my new go to builder! It is hard to find someone to trust, not just with your home but with so much more in this case. Andy, once again, I cannot thank you enough! You really came to my rescue here! I would definitely recommend you and your team for any work in the future. A+++

Job was to convert existing garage into a home office and retain storage space too. Very impressed from start to finish, and would thoroughly recommend (already have to family and friends!). Communication was great, helped to talk through our initial idea and made some recommendations which we took up and made it even better. Flexible to work around our commitments at home, and all elements of the job delivered to a high standard. Would certainly use again when we have another project to do. Thanks.

Roy and his Son did a great job on my kitchen. They were polite and communicative and did what he said he would do. Roy took over this job from a previous bad builder and nothing phased him.

We hired Emanuel through your platform for a garage conversion to a work studio. He was prompt to visit and provide a quote. He started on time and worked efficiently with all the requirements we had. He completed the conversion to a very good standard and we are pleased with his work. He is very easy to communicate with and always keeps his commitment. And his final cost was very close to his initial quote. I would definitely recommend Emanuel for such work and would hire his services again if I need in future.

Bathroom Fitting- 5 Aug 2023
Took way too long with poor excuses for not finishing on time. Left no spare tiles and since one on floor has cracked. Cut corners on piping in my loft resulting in my hallway being flooded and costing to be re plastered and re decorated in hall. All because of lazy plumbing in loft. Don’t think he even trades as a builder any more thank goodness. Or this could happen to somebody else. AVOID
