"Had a window cleaning job that I thought might be too small - this company responded quickly to my inquiry and fit me into their schedule sooner than promised. The worker was pleasant and professional and my windows are sparkling!"

Customers say: True professional

"Isaac showed up on time and took his time cleaning my windows THOROUGHLY. He cleaned every single window in my house inside and out, including the garage, attic and basement, even though I hadn't asked him to. The quality of his work is stellar, and his attitude is pleasant and professional. My windows have never looked better! I would recommend Clean View to anyone, and I've already told Isaac I would hire him next spring."

"Edwin Julia from Duct Kings did a fantastic job checking and cleaning our clothes dryer vent! He also installed a new exhaust dryer outlet as we were having a problem with mice entering through our very outdated one. Even though i am very careful about cleaning the lint trap on the dryer each time , the amount of lint that still got into the vent was unbelievable and I will now hire Duct Kings yearly for an evaluation and vent cleaning. Edwin is competent, kind, hard working and honest. I highly recommend him and Duct Kings! They are a very reliable and a five star company for the reasons cited above!"

"I was very impressed. The two cleaners were both very efficient, personable and professional. His price was very reasonable as I live in a small condo. He did not charge me a high fee as if he were cleaning a big house. Windows are sparkling. I will have them come again when needed...Ty"
