Marc and his team were professional, thorough and very responsive. We just had them install over 20 new windows in our home, and we are very happy. Two thumbs up!

Mark is a great guy and his crew were terrific. Mark's pricing is very fair, the windows are high quality and the work was completed on time and on budge. Very professional. Highly recommend.

Marc C**** and Highland Windows are wonderful! Reasonable prices, great workmanship and excellent service.
