I just wanted to write and say thank you to East Coast Window Cleaners (ECWC) for the great job that they did for us in Lewes, DE. for June 2026. Anyone who lives in Lewes, or visits, knows that every spring your house is coated in pollen and a salt water “crust” that you cannot escape. Usually, I let Mother Nature deal with all of that with a good downpour of rain, but this year, all of that extra cleaning seemed a bit much. ECWC came and took care of everything for me, both inside, and outside. Decks, outdoor furniture, windows, sliding glass doors, and brick pavers all were immaculate. Gone was all the annual build- up of pollen, salt, algae, and whatever else this harsh environment can attach to your house and furnishings. It was not our first interaction with ECWC, so we felt very comfortable with them being inside our house when we were not available. Everything that was moved inside the house to gain access to the windows was put back exactly where it was supposed to be. The house was clean, and no dirt, or leftover cleaning supplies were left behind. ECWC did a fantastic job. We will definitely use them again. Thank you, Andrew Randall Lewes, DE

Response from the owner:Andrew, thank you so much for this! Pollen and salt buildup in Lewes is no joke, and we're really glad we could get everything looking fresh again, from the windows and sliding doors to the decks and brick pavers. It means a lot that you trust us in your home. We'll see you next time!
