I'm Marc Cowan. I created the Highland Window Company LLC. in 2002. After 8 years of window and siding sales and production experience, I joined with my partner who has been installing windows and siding for over 25 years. We provide the highest quality windows and siding available today, at the lowest prices, with the best service and warranty in the business. We understand that our business has been, and will be, built on serving our customers needs. We build a relationship, which includes every customer having my home telephone number for easy contact. With our award winning Alside window and siding products, you can be sure your project will be done right the first time. We can install our windows from the exterior, the benefit being no damage to your interior woodwork. We work very hard to ensure your complete satisfaction. In fact, your final payment isn't due until you are completely satisfied with our work, and have carried out a full inspection with myself.
