“Truly a 5 star company! Price was very competitive and the experience was outstanding. They replaced an oversized bay window and everything went smoothly from start to finish. Great communication from estimate through install. Best of all, they were extremely clean and respectful of my property, which is honestly not typical with contractors. Highland Windows gets my highest recommendation!”

“Couldn't be happier with this company. Honest, returned calls promptly, and was the lowest estimate. Workers were polite and worked nonstop. Job done in a day and a half. Marc came by to see that we were happy. Love the new windows including an odd hexagon window they did a great job with.”
