Window Washing FAQ's

Are you insured?

Yes, we carry general liability and workers comp. Certificates can be provided upon request.

How often should I have my windows cleaned?

We recommend having your windows cleaned twice a year to prevent hard water accumulation and to extend the longevity of windows and screens.

How are the windows cleaned?

All windows are cleaned by hand individually. We use standard window washing supplies, including squeegees, buckets and soft cloths.

What do you use to clean the windows?

We use a combination of mild soap and water to wash your windows. It is environmentally safe, will not leave streaks, and is non-abrasive. We do not use any acid-based products, ammonia, or vinegar.

Do I really need to have the inside of my windows cleaned?

Yes, typically we like to do both inside and outside on your first service. After your first cleaning for the year, you can rotate from inside and outside window cleaning to outside only. Inside windows can stay cleaner longer, but there are some things that can contribute to your inside windows needing to be cleaned more frequently, i.e., if anyone smokes in the house, children, pets, misc.

How long will it take to clean my windows?

Typically cleaning windows can take anywhere from 1 hour to 6 hours; it all depends on the size of the house, how many windows, and when your last cleaning was. Also, if you have any storms, screens, or French style windows, those may add to the cleaning time.

Do I have to be home for cleaning?

If you are a first time customer, we recommend that you are home for your window washing appointment. We like to do a full price quote and would like you to see how we perform the service, and answer any questions that you may have.

If you are having your gutters cleaned, you don’t necessarily have to be home for the gutter cleaning. We can leave an invoice at your home after your gutters have been cleaned. We do ask that you mail in payments within 5 days after the service has been completed. We also ask that you provide us with a phone number where we can reach you if any questions should arise.

If you are having your windows cleaned on the outside only, you don’t necessarily have to be home for this either—as long as any storms and/or screens that are on the outside of your windows can be removed from the outside. We do ask that you mail in payment within 5 days after the service has been completed. We also ask that you provide us with a phone number where we can reach you if any questions should arise.

When is a good time to schedule my appointment?

We do offer same or next day service when available. During the busy season (spring & fall) we do recommend that you try and give one weeks’ notice when possible.

Do you offer service on the weekend?

Yes, for an additional fee

Is there anything that I need to do before your arrival?

We bring our own equipment and supplies. We do ask that all blinds and/or window treatments are open or tied back before our arrival, and that there is a clear path to each window. Please remove any breakables or knick-knacks on or around the window area.

Why should I call a professional window washing company instead of a maid service to clean my windows?

Most maid services use a product like “Windex” and paper towels which will not clean your windows; it will rub the dirt around, which will create a static charge that will attract dirt and dust to your windows. Worst of all, it can scratch the glass. Our window washers use only professional window washing tools and equipment.

What if it rains on the day of my appointment?

We try to closely monitor the current weather conditions. If the weather is questionable on the day of your appointment, please contact us at 847-321-8261. Depending on your windows, we usually will keep the scheduled appointment, do only the insides, and then return on a nicer day to clean the outsides.

Won’t the rain make my windows dirtier?

No, not if they are clean. When your windows are clean, you don’t have any dust or dirt for the water to adhere to. However, if your windows are dirty, rain simply attaches itself to dirt that is already there, often making them look worse.

Why does it look like my windows are foggy (especially on cold or rainy days)?

The main reason for foggy windows is that you may have a broken or damaged rubber seal. The rubber seal is what keeps the gas between the pains from escaping. Your windows will look foggy because moisture gets in-between the panes.

How often should I have my screens cleaned?

We recommend that screen be cleaned once a year.

My screens have never been professionally cleaned before; they look like they have stains on them, will the stains come off when you clean them?

We cannot guarantee that all stains or spots will be removed during the cleaning of your screen. We will do our best to try to remove as much of the stains as possible. Screens that are not cleaned on a regular basis, over a period of time will have a buildup of dirt and grime that can cause stains and spots and sometimes this becomes permanent.

Are Tracks and Frames included in the price for window washing?

No, tracks and frames have an additional charge. Basic window washing includes the cleaning of the actual glass, and wiping down your window sills. Tracks and frames are priced separately.

Why do windows with non- removal grids (true divided lights) cost more?

It is much more time consuming to wash each individual pane one at a time as opposed to washing the whole window in one motion.

Is there going to be a mess on my carpet or will my wall get dirty during the window washing?

The floors will be covered with a drop cloth or towels to prevent anything from dripping on the floor. The workers will also be careful not mark up your walls.

Will the window washer wear shoe covers?

Out of respect for you and your home, our window washers will either remove their shoes or wear shoe covers.

Can I trust the people that you are sending to my home?

Yes, we are fully insured. We hire only responsible individuals and we also do background checks.

Is there a guarantee on window washing or gutter cleaning?

If you are not completely satisfied, please call our office within 7 days of your service date.

What type of payment do you accept?

Payment is due upon completion of services, we accept cash, check, and all major credit cards.
