Bricklaying- 27 Apr 2026
Absolutely disgusting, said i was a FXXKING nit picker, garage not squared, layed block to the outside of one corner and inner at the other corner, joke. Used the bricks for the final wall plate to fill gaps in wall instead of cutting blocks. Wall leaning, even admits this. To many pictures to put on here, this is just one. I only realised this after I let him go, at a cost of 300 for the day. If he replies to this I will post all of the photos for him to see.

What experience do you have with similar extensions in Llanfairfechan?
