What my customers are saying...

"We are very pleased with the quality of work that Sean (DuPont Window Cleaning) has done in our home for the past several years. The windows are not only spotless when he is finished, but they seem to stay clean longer, even after rain storms. We also get compliments on how beautiful our chandelier is - it's sparkling clean! Sean is very professional, courteous and reliable and his fees are reasonable. We would highly recommend his services."
