You have to look at it like this too, foreign labour, the are taught the trade in their own country, working with different materials and working to different regulations.
They also have different standards and levels of pride in their work, a s**t render jobs might look pretty good on a Romanian estate, but obviously it's not up to scratch when it's the side of someone's £200,000 house in a nice area of England.
I have nothing against anyone coming to this country for a better life, but we see all too often, foreign labour bringing their own work ethics and standards.
I had a Romanian guy ring me for a job last week, Andreas, seemed like a nice guy, probably could spread too, ex British Gas apparently doing EWI, would have probably saved me a few bob too, but it's not worth the risk, his finish would have probably been to a low standard.
You see it all to often, I posted pictures the other week of a Chinese k rend job, I'm sat on my patio now overlooked by a Chinese extension, it looks abysmal, gobbo snots, crooked brickwork etc.
Just different standards, and if customers want lower standards so they can pay a lower price then let them have it.
I'd put rendering your house on par with buying a car, both sit on the front of your house for everyone to see, both should show their value and sometimes people just fancy paying £300 for a P reg Ford Fiesta rather than buying something nice that looks good, will last and probably save you money in the long run.
