We live on adjacent to a busy street and decided to buy windows to install over our existing windows to help reduce the noise. We purchased the windows and they arrived in December. After New Year's, we decided to have them installed by someone who had done it before since we wanted it to look good in our house (vice my McGyver duct tape style). Lance and his assistant arrived as scheduled and were able to install 2 of the 3 windows, but the 3rd window was too narrow for the glass door he was installing it over. Lance pointed out that if he installed this window, it may crack the existing glass on the door. After contacting the company (with some wise words from Lance), they agreed to ship another window since the measurements were smaller than needed. After the replacement window arrived, Lance came out and had it up and looking great. The windows look great and function as advertised (not quite soundproof, but reduced noise is much better than it was before the windows were installed).
