This is the best window cleaning company we have ever hired. The men who came were attentive to detail, careful about some leaded glass windows we have, and overall very professional. We had a lot of difficult windows, some with storm windows and screens that had to be disassembled to be cleaned. Terrific job all around. They suggested pressure treating our terrace, which we had not thought of, and did a great job with that too. The price was very reasonable for a long day of work. We couldnt be more satisfied with Perfect Panes.
