Super Window-Cleaning Job

"This company is terrific. They did an amazing job on my 9th floor condo's windows. It was a big job; I have over 58 windows, very large and small. Dwayne did a super window cleaning job. I now have a clear view of downtown London and One London Place is spectacular, day or night. Call them; you will not be disappointed. Price is very, very competitive. 519-681-7827. I seldom recommend anyone or any company; no hesitation recommending Blue Diamond."
