Just a short message to let you know how we appreciated the work of your employees. They not only completed a very difficult task in bringing our building up to the requirements that the Northbrook Fire Dept demanded but they did the job without causing any problems with the condo owners. I did not hear of one negative word from any person. Your people not only did a neat job but the cleaned up so that you never knew they were working in each condo. Thanks for a job well done!
