Why Window Washing Companies Are Not All the Same
Updated: Sep 23
Window washing companies are not all the same because the result on your glass depends on four things that vary from one truck to the next: the cleaning method, what the price includes, whether the company is insured, and who actually shows up. Two quotes for the same Wilmington home can be $150 apart and describe two completely different jobs.
As one of the highest-rated exterior cleaning companies in the Wilmington area, we get asked this all the time, usually by a homeowner holding two quotes that do not add up.
Earlier this month we cleaned a home in Brunswick Forest in Leland. The job was outside glass only, plus the skylights, plus the inside of the sunroom. That one house explains this whole post. A second-story window, a skylight, and a sunroom full of screens each call for a different tool, and a window washing company that shows up with one bucket and one squeegee will do at least one of them badly.
What Actually Separates One Window Washing Company From Another?
Professional window washing is the cleaning of the glass, the frames, the sills, the tracks, and the screens, done with tools that leave no streaks and no water spots. That definition is the problem. Half the companies advertising window washing in Wilmington and Leland stop at the glass.
Here is the checklist we would use if we were hiring a window washing company for our own parents.
What to check | A basic window wash | A complete window cleaning |
Glass | Outside only, sometimes inside | Inside and outside, both sides of every pane |
Screens | Left in place or leaned against the house | Removed, washed, dried, and put back |
Tracks and sills | Skipped | Vacuumed and wiped |
Storm windows and French doors | Extra charge or skipped | Included in the quote |
Furniture near windows | Homeowner moves it | Crew moves it and puts it back |
Upper windows | Ladder leaned on the siding | Water-fed pole from the ground |
Insurance | A "yes" on the phone | Certificate emailed on request |
Price | An estimate, adjusted on the day | Flat price from photos, nothing added |
None of those line items show up in the number on the quote. They show up in what your windows look like a week later.
The differences matter more for older homeowners than for anyone else. If you cannot climb up to check the upper tracks, or move a heavy dresser away from the bedroom window, you are relying on the window washing company to do the parts you cannot see or reach. That is the whole reason to hire one.
Does the Cleaning Method Matter, or Is a Squeegee a Squeegee?
Yes, the cleaning method matters, because the two main ways to wash windows leave different results on the glass and carry different risks to the home. A squeegee in trained hands and a water-fed pole with purified water are both professional tools, and every window washing company owns at least one of them. A garden hose and a rag are not.
A water-fed pole is a long telescoping brush that runs purified, mineral-free water up to the glass from a tank on the ground. The water is filtered until nothing is dissolved in it, so it dries without spots. The cleaner scrubs from the ground, rinses, and moves on, which is how a two-story home in Waterford or Landfall gets its upper windows cleaned without a ladder ever touching the siding.
The squeegee method is the traditional approach: a soapy applicator loosens the dirt, and a rubber squeegee blade pulls the water and the dirt off the glass in one stroke. It is still the best tool for inside glass, for French doors, and for anything with a stubborn film on it. The skill is in the stroke. A cleaner who has done thousands of windows leaves no lines. A cleaner in the first month leaves them on every pane.
Then there is the glass that neither tool fixes on its own. Hard water stains are mineral deposits left behind when sprinkler water or salt spray dries on a window over and over, until the minerals etch into the surface and look like a permanent haze. In early September we cleaned the windows on a home in Wilmington where the lower glass on the lawn side had exactly that haze from the irrigation heads. Regular cleaning had not touched it in years. It took a separate mineral treatment, worked in by hand before the squeegee pass, and the homeowner had assumed the glass was ruined. A window washing company that does not offer that treatment will wipe the same haze and hand you a bill.

We use both methods on almost every house. Pure water on the outside upper glass, squeegee on the inside and the ground floor, and hand treatment wherever the sprinklers have left their mark.
How Do You Know a Window Washer Is Insured and Safe to Let Onto Your Property?
You know a window washing company is insured when it emails you a current certificate of insurance on request, naming a general liability policy and, if the company has employees, workers' compensation. Anyone can print "licensed and insured" on a truck door. The certificate is the proof.
General liability insurance is the policy that pays if the crew breaks a window, cracks a skylight, or drops a ladder through a screened porch. Without it, that repair comes out of your pocket or ends up in small claims court. Workers' compensation covers the cleaner if he falls. Without that, an injured worker's medical bills can turn into a claim against the homeowner. We wrote a full guide on how to tell if an exterior cleaning company is actually insured, and the North Carolina Department of Insurance can confirm that the carrier named on a certificate is licensed in the state.
Safety is the other half of the question. Window washing happens on ladders, and the Occupational Safety and Health Administration has partnered with the International Window Cleaning Association for years specifically because falls are the biggest hazard in the trade. A window washing company that cleans your second story from the ground with a pole has removed most of that risk before it ever pulls into your driveway.
The people matter as much as the paperwork. Window Cleaning Wizards is two brothers, Nick and Chris, and we are the ones who show up. Nobody is subcontracted, nobody is new this week, and the person who quoted your job is the person cleaning your windows. If you live alone in Porters Neck or St. James Plantation and want a family member there for the first visit, say so when you book and we will schedule around it. Our post on how background-checked cleaners protect your home covers what else to ask.
Why Do Two Window Washing Quotes for the Same House Come Back So Different?
Two window washing quotes for the same house come back different because one of them is pricing the glass and the other is pricing the whole window. The low number usually leaves out the screens, the tracks, the storm panels, or the inside, and those either show up as add-ons on the day of service or simply do not get done.
In Wilmington and Leland, a complete inside-and-out window cleaning on a typical three-bedroom home runs about $150 to $450, depending on the number of windows, the number of stories, and how many screens, French doors, and skylights are in the mix. Outside-only cleaning runs roughly 40 percent less. A quote well under those ranges for a two-story home deserves one more question: what exactly is included? Our window cleaning cost guide for Wilmington breaks the ranges down by home size.
Four questions sort a fair window washing quote from a cheap one.
Is the price for inside and outside, or outside only?
Are screens, tracks, and sills included, or extra?
Will you move the furniture away from the windows and put it back?
Is this the final price, or an estimate you will adjust on site?
Window Cleaning Wizards quotes a flat price from a few photos, and that price is the price you pay. Screens, tracks, sills, storm windows, and French doors are included. We move the furniture and put it back. If we miss something, we come back and fix it under our satisfaction guarantee. That is not a sales pitch. It is the list of things the cheap window washing company leaves out.
Window Cleaning in Wilmington, NC
Earlier in September we did a bundled visit at a home in Waterford in Leland: inside-and-out window cleaning on the same day as a soft wash of the siding. Booking the two together saved the homeowner a second setup charge, and the windows were washed after the siding rinse so no runoff landed on clean glass. That kind of sequencing only happens when one window washing company handles both jobs.
Frequently Asked Questions About Choosing a Window Washer in Wilmington NC
Should I hire a franchise or a local window washing company in Wilmington?
Either can do good work, but a local owner-operated window washing company gives you the same crew every visit and an owner who answers the phone. Franchises rotate technicians and route calls through a center. In Wilmington and Leland, ask who specifically will be at your house and whether that changes from visit to visit.
Do window washers clean screens and tracks, or just the glass?
It depends on the company, which is exactly why quotes vary so much. Some window washing companies clean only the glass and charge extra for screens, tracks, and sills. Window Cleaning Wizards includes all of them in every inside-and-out cleaning.
What should the window washer do if it rains right after the cleaning?
A good window washing company will tell you that clean rain does not spot clean glass, because the spots come from dirt already sitting on the window. If your windows do spot within a few days of a cleaning, the company should come back and touch them up at no charge. Ask about that guarantee before you book.
How often should windows be washed in Wilmington and Leland?
Most homes here need professional window washing twice a year, once after spring pollen and once in the fall. Homes within a few miles of the beach at Wrightsville Beach or Carolina Beach often need a third visit because salt film builds faster. Our guide on how often to schedule window washing in Wilmington covers the timing.
