I originally booked multiple building companies for a quote for my home improvements. Carl was friendly on initial meeting and give me good explanation on how best to carry out my project with the maximum impact to use my space. He was very efficient in getting back to me with his quotes and I could clearly see the breakdown of each individual project. The timescales that he recommended were also managed within the given timeframe that was advised. The company was very clean and tidy and always made sure that any rubbish was taken and disposed of the same day. The quality of the workmanship was very good and I feel that the standard of finish for the end results were also very good.

Driveways (Tarmac Surface)- 2 Nov 2020
Richard had only just joined MyBuilder and approached me to look at the job. He has had many years experience in construction and civil engineering. I had a few technical type questions which Richard answered obviously knowing his stuff unlike other people who looked at the job. Communication was good throughout the process and the organisation was slick. It was nice to see the management checking the quality of the work (not that it needed it) which to me demonstrated a pride in the job. The drive was finished today and it looks amazing. I would highly recommend Bardic Contruction.

Valleys Plastering & Construction
Rating: 5 out of 5
Extension Builder in Neath
I have been plastering for 25 years, from lathe and lime, float and set to skimming and k rend, I can do it all. Nothing is too big or complex, and I'm quite happy doing a little ceiling here and there. Shed loads of experience and plenty of passion. Have built plenty of extensions and new builds from scratch over the years with my team but happy on the trowel now. I have been plastering all of my adult life I am 40 years young. Thanks
