I've just received a rather distressed phone call from oldest son. They'd just laid new carpets in their flat this week. They had electricians in today to put in new lighting. Electricians clumped through house and have left oily/muddy footprints or stains of an indeterminate nature all over the carpets. Son has tried desperately to get stains up with carpet cleaner but probably made it worse.
What to do? I've told him to get on to his insurance company, but does he have any comeback over the sole trader who employs the electricians?
Where I live, even if a tradesman comes to make a quote, he routinely takes his shoes off or covers them in those blue elastic over-socks.
