Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

I am ever so happy with my bathroom, they even went extra mile in connecting my light switch where I needed it to be even though it wasn’t part of the agreement. These guys are spot on with their job. Will definitely recommend them which I’ve already done. Lol
