Testimonials from Island Lake

Rich - Island Lake, IL
On Easter Sunday my main backed up and we couldn't run water or flush the toilet or water/sewage would rise into the house! Black Diamond responded quickly and fixed the problem! I couldn't believe how reasonable the cost was plus we got a one year guarantee! I wouldn't use anyone else after such an awesome experience! Thanks Black Diamond!!

Kim - Island Lake, IL
Wow, Wow, Wow.... Jimmy, Ross and Ryan are Supermen!!! They removed from the foundation of my house the old piping for my gas generator, which was starting to leak and dug a trench to put the gas line underground. They never made a mess of the landscape and left it looking better than is was before the work was started!!! Perfect gentlemen, hard working and pleasant!!! I would highly recommend them and Black Diamond!! Thank you, thank you, thank you!!! I now feel safe without any gas leaks.
