Marvin Window Reviews

Ann Erickson Lang

We're thrilled with our Marvin Infinity windows and the entire Gravina's Window Center of Littleton team. It's now been several months since we had them installed. We've noticed that they kept the house cooler during our ridiculously hot September weather and are keeping the house warmer now that we're moving into winter. The installation team was hard-working, efficient, highly professional and just really nice! No last-minute cost adjustments. Highly recommend.

Our experience with Gravina's Window Center of Littleton was excellent. The installation crew arrived earlier than projected by scheduler (which was great) and went right to work. Floors were protected with runners and plastic sheeting placed over the shelves. Installation was very fast and well done. Everything was cleaned up to our satisfaction. I gladly and enthusiastically recommend this company.
