Real Feedback from Our Customers

We purchased Kohltech windows to update our home in 2023 through HLH and the process was made very easy for us with the assistance of the great staff at HLH! Extremely helpful and friendly...you can tell this is a family-owned business with a vested interest in the community. They know how to do things right the first time. The windows are amazing and immediately noticed how quiet and warm our home became after the installation. A technician from Kohltech came in to complete a few minor adjustments shortly after installation and since them we have had no issues, just the enjoyment of our new windows and quiet, warm home!
