Exterior Windows

Clearing all access to the windows is necessary for exterior window cleaning. Enough cleared space is needed to set up and position ladders. Here are some things you can do that will aid in making your exterior window cleaning easy and safe.

  • SHEDS – If your shed obstructs one or more windows, it needs to be moved first so you or the professional window cleaners can safely access and clean the windows.

Interior Windows

For interior window cleaning, removing all decors and furniture off the windowsills like plants/planters, fragile decorations, and picture frames is very helpful and recommended.

Clearing objects around the window area and off the shelving from Garden or Bay windows in the bathroom or kitchen can also help access the glass easily. Smooth and fast window cleaning is attainable if you remove all furniture that obstructs access to your windows. Professional window cleaners can help you move larger furniture or items such as couches, large beds, or cabinets.

How Well a Company Performs

That is why it is so important to choose carefully when it comes to this type of home care specialist.

Windows should be professionally cleaned at least one time per year.

Windows are regularly exposed to droplets of condensation and dirt from the outside environment, which can lead to cloudy or dirty windows. If left unchecked, over time these particles will collect and build up on your windows, causing permanent damage.

A professional window cleaning company will help eliminate the growth of mold and mildew as they wash with special solutions that break down layers of grime without scratching glass. Professional cleaning typically includes removing screens and sills after a thorough power washing – this step is crucial in order to completely remove algae from window wells caused by water seeping over pools above ground level – otherwise you’ll continue to have an ugly green area around your windows for a long time!

Yes, but not in the direct sun.  It depends on the weather conditions and difficulty of the surface. In general, it is best to clean windows when they’re wet because there will be reduced chances of streaks or water spots. However, it can depend if you are cleaning clear glass, tinted glass, or solar film (or other) coatings. It’s also better for more difficult surfaces such as insulated glass units because once a streak occurs in the coating it may not come off without scratching.

If you have access to commercial window washing equipment such as squeegees with soft rubber blades specifically designed for windows and mirrors, and powerful supplies of hot water at high pressure to avoid streaking on wet surfaces then yes you can safely wash your windows during sunny days.

-Thanks Byron at Ambassador Window Cleaning in South Carolina:

It depends. If you know what you’re looking for, and where to find it, and how the power of the sun affects washing windows, then yes – commercial window cleaners in Oakland can be expensive because of all that is going into getting the job completed; drive time, equipment, tools, and the labor required.

Remember to factor in your location within this answer. For instance, some cities are notorious for there high prices – which might make budgeting more difficult as oppose to some cities with cheaper prices. Keep this mind when price-budgeting a job such as window washing!

A great way to save money is by finding another business that is willing to trade or swap services with each other or do certain things in return for others like car detailing after window washing in order to lower costs overall – swapping services

Yes, if you can.

Slightly less than half of all American adults tip cleaning and housekeeping professionals when staying at a hotel, but tipping is completely voluntary. I believe that we should support those who provide good service to us – while this may sound altruistic or another buzz word as economic stimulus (or some nonsense term); people need to live and feed themselves somehow. If you’re able, it’s a good idea to tip the window washer at your hotel or home building for washing their windows from time to time.

Hiring a business coach is one of the best ways to start up a pressure washing business. One way to find potential coaches that match your needs is by looking at their past successes; you can research other businesses they’ve helped grow on sites like LinkedIn.

As soon as you establish contact, set up an initial meeting with them, during which talk about your individual goals and what you want to get out of the coaching process. Then every week check in about progress (either over email or via video conference), discuss progress against goals, and brainstorm creative ideas for moving forward. Also be sure to ask any questions related to accounting, finance, organization, or hiring employees that may arise while working together.

Thanks to Brown’s Pressure Washing for this great advice!


A professional squeegee is the best way to wash windows. The quality of the squeegee blade will set it apart from other tools, so you’ll probably want to buy one separately. The key when window washing with a squeegee, pay close attention to smoothness and bending when applying pressure to the edges of the squeegee.

There’s no exact science for this, but in general scrubbing hard isn’t necessary; just go easy enough that you can feel that there are no raised areas or edges on the window itself before you stop scrubbing altogether. Rinsing well is also important because dirty water can often leave marks after it dries (and doesn’t stay off). If your window has really stubborn dirt or film, try using vinegar mixed with hot water for a little more cleaning power.

Windows should definitely not be washed in direct sunlight as it will cause enormous and unsightly streaks and possible damage to the window. According to most home improvement experts, windows should only be washed when the sun is at least two hours away from setting, has already set or is coming up on morning with a side of fog. On these occasions most windows will not be affected at all by the light.

With that said, if you’re desperate enough to need your windows cleaned now then there are steps you can take before washing them. Use lots of water and adding vinegar will help from evaporating so you can have enough time to squeegee them before the sun dries the glass.
