Was called out a few days ago to give a W/C quote for a large house built in the 70’s.i noticed that they were double glazed windows, which the owner said were fitted about 20 years ago.All was fine until i saw the windows…they were pretty dirty.
Now it was nothing that i couldn’t handle and i proceeded to clean them today…however after i had cleaned both interior and exterior of most the windows It appears that on most windows the insides of the two panes are dirty as well as the outer facing sides of the two panes of glass…
so essentially the space in between the two windows of the double glazed window is dirty…i.e the windows are dirty from the inside out.
I hope the above makes sense to you…how can i alleviate the problem as the customer refuses to pay me even though i spent most of today cleaning her windows…is their any way of cleaning this inside dirt…i have never come ac cross it before
looking forward to some replys
