Hi Mike, did you cut the fir trees back at all when you were doing other pruning in your garden?
I'd agree that trees - like hedging - will always benefit from having a clear area round them, free from grass or any other weeds and planting, but I wouldn't have thought mature trees would have suffered too much, and it seems from your description they're a good size if they're blocking an ugly view. I'm also quite surprised that whoever laid the new lawn took it right under the trees, but that's a different issue. I have a mature conifer in the corner of my back garden which has had lots of turf lifted from other areas, turned upside down and built up round it's base last year - to no negative effect.
