Residential FAQs

How often should I have my windows cleaned?

We clean some home windows monthly, others bi-monthly, four times a year, three times a year or annually. It is your preference how often you would like them cleaned, even if it’s just once.   We suggest our Great Lakes exclusive, the Once-a-Season program that offers the best value, please inquire about special pricing. We would also suggest that it is best if your windows never go much longer than a year between cleanings, because the build-up of dirt can lead to stains which are difficult to remove such hard water spots from sprinklers and oxidation that can come from metal screens resting on the glass.

Are your window cleaning technicians experienced?

Our technicians are fully qualified experts who also love their jobs. Our average window cleaning technician has over 10 years of window cleaning experience with us. Each window cleaner is fully insured and bonded. And each and every one is careful, courteous, and concerned about your comfort and the condition of your home—from their uniformed shirts down to their clean, white socks (after all, we do often remove our shoes when cleaning windows inside homes)!


What if it rains?

Since it usually doesn’t rain all day, we kindly ask that you allow us to clean the INSIDE of your windows first. In most cases it has stopped raining by the time we are ready to clean the outsides. We appreciate that you have arranged your schedule for this appointment and this will enable us to take care of you with the least amount of disruption to your schedule. If we need to come back to clean the outsides we will endeavor to do it the same day or same week. You will not need to be home. You will be billed by mail if you are not home.

Remember our “NO SPOTS IF IT RAINS GUARANTEE”. We guarantee there will be no spots from rain on your windows after we clean them. If you see spots up to 48 hours after a cleaning, please give us a call and we will happily re-clean them at no charge and no hassle.


Can I get an estimate for residential window cleaning before you come to my home?

Yes!  We can do that all from the outside and you do not need to be home when we perform the estimate.  All we to do is take a quick count of the number of different types of windows in your home (awning, bay, casement, double-hung, french, jalousie, picture, sliding, etc.) We will call you with an estimate .Please don’t forget we can also clean your chandeliers, mirrors, and other glass surfaces!


Do you have references I can check?

Of course! Take a look at what our happy customers have to say, just click on reviews at the top of the page or under the Residential section. This is a brief sampling of hundreds of comments our generous customers have written about their service experience. Let us know if you need any more specific details. We have 30 years of experience of endeavoring to exceed our customers expectations at every visit. Chances are that we take care of your neighbor’s windows!   Thank you for asking.


What is the most economical way to have my windows cleaned?

We feel the best value is found in our exclusive Once-A-Season program, with special program pricing. Four months a year— March, June, September and December—we’ll make sure the exterior of your windows are sparking clean and free of accumulated dirt, spots and smudges. Don’t worry about calling for an appointment because we’ll do all the remembering for you—you don’t even need to be home. (The exception is the month of March, when we recommend we clean the inside your home windows also and save 25%)


Are windows that are stained or have hard water spots more difficult (and expensive) to clean?

In a word, yes. Windows that have been repeatedly exposed to water (such as sprinklers), pollen, bugs, acid rain, salt and bird droppings, or simply haven’t been washed for a while take longer to clean. That’s why we recommend our Once-A-Season program, which really pays off in the long run.


What if I want my windows cleaned on a regular basis? Do you clean year ’round?

We clean windows every week of the year. Enroll in our Once-A-Season program. Take pride in your glistening clean windows all year long, rather than just once a year!


What areas do you service?

Great Lakes Window Cleaning provides residential service in the counties of Ingham, Eaton, Clinton, Jackson, Shiawassee, and some parts of Washtenaw and Livingston counties. These include the following; Lansing, Okemos, DeWitt, Williamston, St. Johns, Grand Ledge, & Jackson. Our Lansing Office services homes in the Ingham, Eaton and Clinton County areas.  Ask about other areas.  Commercial & High-Rise service is available statewide.


What can I expect during your technician’s visit?

We start by arriving on time. Next, we take care to be concerned to protect your home’s surfaces—such as interior flooring, floor coverings and furniture as necessary, as well as the exterior landscaping, flowers and your homes siding. Then we gently wash your glass surfaces—thoroughly removing dirt, spots, fingerprints, smudges, grease, and film—then squeegee them to a spot-free shine, or if conditions are appropriate we can use our ultra-purified, spot free rinse to leave the exterior surfaces of your windows even cleaner!.


Do I need to do anything to get ready for your technicians?

If you would be so kind, since our working hands will often be wet, we appreciatively ask that you move anything off the window sills or window area such as plants, nick-knacks, papers, etc. Please note that we also ask that you move furniture away from windows so that they are accessible. We can assist with moving furniture if needed, but will not be responsible for any damages if they occur.


Will there be any mess to clean up afterward?

Absolutely not. Other than the spotless windows, you won’t know that we were there.


Does someone need to be home while you are cleaning my windows?

Technically, no. But that is your preference. Many of our customers let our trusted employees into their home as they are going off to work and then ask our technicians to lock the door on the way out, much like a house cleaning service. Most of our technicians have between 4-14 years of experience.


How long will you be washing my windows?

One answer to that question is, “As long as it takes for them to sparkle and shine!” Most homes without storms are completed inside and out in two to four hours. We send larger crews when the homes are larger. Please ask when you schedule your appointment if that is a concern.

Are you competitively priced?

You’ve heard the saying: “You can have service, quality or price. Pick two.” Yes, we’re competitively priced, but we’re not the cheapest. We’re efficient, but we’re not slap-dash. But most importantly, we do window cleaning right,  from implementing proper safety precautions to the quality of the work we perform, Great Lakes Window Cleaning stands out as the best choice for Mid-Michigan’s commercial buildings. There is a reason more area businesses and building managers choose Great Lakes Window Cleaning for their window cleaning needs than all our competitors combined!


What is the most economical time of year to have my building’s windows cleaned?

February, one month earlier than most people are thinking about it, will usually result in savings up to 30%. If you have your windows cleaned only once or twice a year it doesn’t really matter which month, except for the savings. Or, you can choose to have the inside only completed at that time, if that is your preference.


What makes Great Lakes Commercial Window Cleaning unique?

In a word respect. We have high standards. We require a clean cut and professional look, attitude and decorum from each worker. We start out by recruiting and hiring high caliber people, then we all work to maintain a company culture and atmosphere where professionalism and dignity are highly valued. This translates into how our employees treat each other and our customers, including our customers’ property and tenants.

The following quote hangs in our conference room as a reminder to each of us:

“Watch your thoughts for they become words.
Watch your words, for they become actions.
Watch your actions, for they become habits.
Watch your habits, for they become character.
Watch your character, for it becomes your destiny”

Are you insured?

We are fully insured. We have a $1 million Liability Policy, and every technician is bonded and covered by workers’ compensation. But that’s just the beginning. Every Great Lakes Window Cleaning technician has been trained to think and act safely, because lives can never be sacrificed in order to cut corners or increase profits.  Ask to have an Insurance Certificate sent to you.  We NEVER use sub-contractors or temp workers in any attempt to avoid the legal and moral obligations of employers.


Are your High Rise crews safe?

Since 1989 every high rise building we have serviced has been serviced without accidents, injuries or OSHA fines.

Great Lakes Window Cleaning has been a leader in window cleaning safety for more than 20 years. We have an exceptionally low workman’s compensation rating as a result of our training and company culture.  We support and endorse the national window cleaning standard ANSI/IWCA I-14, the industry standard for window cleaning safety. We do not shirk it, criticize it or avoid implementing it, as some do, because we believe in it, even when it requires extra time or we lose work because building owners do not support the safe window cleaning standard.


What causes hard water spots and stains?

Hard water stains can result from a variety of situations, including sprinklers, condensation, building run-off, chemicals, and oxidation from metal screens. Over time, mineral deposits in water collect on the glass and appear as a hazy white or sometimes yellow film. If left on the glass, this film will etch the glass over a period of time.
