"I was extremely pleased. The men who came to do the work were professional, polite and did more then I expected. They exceeded my expectations. There were four or five workers which enabled them to get the job done in a superior and timely manner. They were in and out so quickly. The end results were sparkling, clean windows and no mess left behind. Hard to find this kind of service in today's world. I tried to leave a tip, but they refused. Sincere appreciation" - Ruth V.

"My windows have never been this clean and it is simply wonderful! The cleaning crew also did a fantastic job paying attention to details that I don't normally notice. The workers were very courteous and respectful which you don't find everyday. Obviously a top notch organization all around." - Cheri M.

"The men who cleaned my windows were the best. Attention to detail cannot be beat. Thank you so much. You did my windows the way I would have done them--if I could have!" - Ruth G.

We will definitely be using Markatos again and will refer them to neighbors and friends." - Susan B.

I was really impressed with the service on all levels, from the bid process to scheduling to the work itself. The window cleaners did a fantastic job, very thorough and probably even better than I would have cleaned them myself. The workmen were courteous and careful of the house." - Judy P.

    “The guys that came out to power wash my house did an amazing job. They didn't disturb any of our surrounding plants/garden beds and got our house spotless.
