All I can say is that Emil's is great!! I got their name from a neighbor who had extensive concrete work done by 2 different contactors. The difference was day and night!! I hired Emil's and was not disappointed, and that was 9 years ago and my driveway, sidewalk, and walkway are holding up great!! You really do get what you pay for - beware of low budget contractors when it comes to concrete.
Also, they do work in Seattle despite being located on the eastside.
