Window Washing & Window Cleaning 

One of the first things a customer will notice when seeing your business from a distance and before walking inside is the clarity of your glass doors and windows. It makes a big difference when your glass surfaces are clean and streak-free. Markatos Services Inc. goes beyond simply cleaning them. First, we target debris, old tape, etc., with a scraper blade, clear the edges of any buildup, then we use brand name window cleaners to leave your windows with a polished shine. The difference will be noticeable to you and most importantly, your customers.
