THIS WEEK WE REPLACE A 2ND OLD ANGLE IRON LINTEL WHICH IS RUST DAMAGED AND HAS "BLOWN". WE SWAP IT FOR A NEW GALVANISED ONE AND REPLACE THE CAVITY TRAY ABOVE IT TOO .
MANY HOUSES HAD THESE OLD POOR QUALITY STEEL ANGLE IRONS INTALLED IN THE 60S ,70S AND 80S AND NOW MANY HAVE DETERIORATED AND STARTED TO DAMAGE THE HOUSE BRICKWORK.
THE RUST STARTS WHEN THE LINTEL GETS WET FOR LONG PERIODS OF TIME . ONCE IT STARTS IT CANT BE STOPPED. THE RUST EXPANDS VERTICALLY AND EVENTUALLY LIFTS THE BRICKWORK ABOVE WHICH IN TURN OPENS UP CRACKS LETTING IN MORE WATER AND SPEEDING UP THE PROCESS.
ON THIS HOUSE THE BRICKS (LONDON TUDOR) WERE POOR QUALITY AND THE SAND AND CEMENT WAS TO WEAK TOO MEANING THE WHOLE WALL WAS VERY POROUS .
MANY PEOPLE SEE THE TELL TALE CRACKING AT EACH SIDE AT THE TOP OF A DOOR OR WINDOW AND JUST HAVE IT POINTED . ALL THIS DOES UNFORTUNATELY IS MAKE IT LOOK BETTER , ONLY REPLACING THE LINTEL WILL CURE THE PROBLEM
THIS LINTEL IS A BIT AWKWARD TO PROP AS WE WERE ON A SCAFFOLD. WE PUT THE ACROWS CLOSE TO THE VERTICAL SCAFFOLD TUBES FOR STRENGTH PLUS WE WERE ONLY PROPPING A SMALL PORTION OF THE PIKE ABOVE SO IT WASN'T TOO HEAVY .......ENJOY 👍🏽
