Living on a new build estate in a TW house this doesn’t surprise. As well as the mix they lay bricks in pouring rain with nothing to protect the fresh mortar. A lot of the houses that had rendering had to have them re rendered as it had blown within 2 years and one of my close neighbours garden wall is falling over,
Sockets not wired in, baths not sealed to the wall, thermostats wired the wrong way round, pipe leaks from poor joins happening within walls, paving stones cracking because of poor dot and dab mix, uneven paths and pavements, drainage issues, one house even had a little stream running through their house at one point. Oh how we laugh.
Im not complaining because we are grateful for a roof over our heads (though the thermostat issue - we seem to be the lucky one shouted with such stupidity - makes it cold in winter either in the living room or the rest of the house - we have to choose which ). If we had paid for our house we’d be might peed off.
Perhaps a giant billboard should be erected on every site reminding bricklayers that it's
One part cement to 5.5 parts sand
with adjustment to the ratio depending on the prevailing conditions.
