So, first clean on Army Officers house.
Very dirty frames and windows at front of house.
Landing / stairs window about 3'x2' upvc type sealed unit.
Cleaned the frame and moved to lounge window. Cleaned lounge window frame.
Back to landing window, cleaned glass and rinsed. All ok
Cleaned lounge glass and rinsed.
Turned round and immediately noticed a crack from bottom left corner to top right corner in the landing window.
Water at 44 degrees, Gardiner superlite brush.
Couldn't have banged the window, angle too steep and it was ok after rinsing.
Saw the guy who was ok. Going to say it was the weather to the maintenance company.
Failing that I have insurance on glass worked on.
Any thoughts guys?
