left category pages look too small to read, make them a bit bigger size.
website looks nice though
I agree, the left link menu font size is far too small to read without zooming in.
Also the front page is too long, not many would be bothered to scroll down and read all that! try and not to have too much text as to have to scroll on the front page i recon.
And finally everything on the front page needs moving upwards, this would also avoid all the scrolling down. i think it could be achived with a smaller depth on your header picture! and if it was my site i would have the third link as "window cleaning" not "contact us"
but overall it looks professional! very well done!
