HSG has always been there whenever I needed any type of work, most recently for water proofing. Due to the heavy rains we had a small water leak on the 15^th floor, all I had to do was to place a call to HSG and they immediately came up with an action plan. Response times are great and the staff are always professional and courteous

Thank you HSG for being my one stop vendor for window cleaning, metal restoration, pressure washing and water proofing.  We truly appreciate you and your entire team, and we look forward to our continued partnership.  Thank you, Alicia, for always making sure everything looks great!!! 

I have used HSG for many years and without a doubt I will continue to use them in the years to come.
