treble your normal price per window, and if they are georgian....run screaming down the road
Buiders cleans are a real pain, do not be afraid to load up your prices. For a fixed price, treble your normal cost, maybe even more than that.
If you are doing a house that has large, real wood georgian windows it will take yo up to 5 times as long to clean them.
It does of course depend on the standards the builder expects of his tradesmen.
If they have done their job properly then the work you will have to do will be little more than normal clean.
If the tradesmen have been sloppy, you will have compo, paint, putty and or silicone to remove, even worse, if the painters have been careless and the walls have been painted you might also have the silicone based water sealant all over the glass too, and this is a total sw!ne to get off.
DO NOT BE AFRAID TO AT THE VERY LEAST TREBLE YOUR PRICE FOR A FIXED QUOTATION!!!
Also make sure you point out to the builder any scratches that you might see, and if there is sand and cement (compo) on them, point out the fact that this may well cause scratches on the glass.
Scratching glass is not an easy thing to do, not for us window cleaners, anyway most scratching is caused by clumsy decorators and their sandpaper. But if you are doing initial cleaning you must be very aware of the fact that after the windows are clean, any marks, scratches or flaws will show up, and the odds are, unless you have had the sense to point out these possible problems, you could well be blamed!!!
So be warned!!!
