No! It is important for anyone hiring a window cleaning service to ask the right questions and get the right information. Some window cleaning services wet the glass and squeegee it dry but skip the middle step which is agitating the window to remove the actual grime. We would hate to see you pay for a wet and wipe instead of a quality clean. Also take into consideration all of the things that are important to you when hiring someone. Will they work with you when it comes to rescheduling due to poor weather? Do they remind you of upcoming appointments? Are they educated, if you ask them questions do they have the answers? If you ask us anything about window cleaning, water leaks, water staining, different abrasive materials that can and cannot be used on glass, fogged windows etc we have the answers because we specialize in windows. Some companies offer window washing as an add on service, for Denver’s Window Shine window washing is our primary service. There is a difference between hiring someone who specializes in painting for example and hiring someone who kind of does painting along with 6 other things and window cleaning is no different. We are window cleaning professionals not a company who adds window cleaning to 5 other services to sell you one stop shop.
