We write a lot of guides on this blog — how to get streak-free glass, when to clean your gutters, whether power washing is safe for your siding. But we rarely stop to answer a question customers ask us all the time: “Who exactly is coming to my house, and why should I trust you?” This post is our honest answer.
We are Window Washing Expert, a locally owned cleaning company that has served Chicago and its suburbs since 2012. In this article we will share our story, the standards every technician follows, the services we are known for, and the reviews and neighborhoods that keep us busy year-round. If you would rather just talk to a person, call (224) 394-4494 or request a free quote — most requests get a response within 30 minutes during business hours.
Our Story: From One Ladder to Three Chicagoland Offices
Window Washing Expert was founded in 2012 with a simple mission: deliver reliable, high-quality cleaning to the homes and businesses of Chicagoland — and treat every property like our own. We started small, built a reputation one clean window at a time, and grew because customers kept referring their neighbors.
Today that same company operates from three offices so we can reach you faster and keep drive times short:
- Buffalo Grove — 906 Stradford Cir, serving the North Shore and northwest suburbs. See our Buffalo Grove hub.
- Libertyville — 375 W Winchester Rd, covering Lake County communities like Lake Forest and Lake Bluff. See our Libertyville hub.
- Lombard — 350 W 22nd St ste 160, our newest office for DuPage County and the western suburbs. See our Lombard hub.
We are still locally owned and operated and deeply rooted in the community we serve. You can read more about how we got here on our About Us page.
What Makes Window Washing Expert Different
Insured, background-checked, uniformed crews
When you invite a service company onto your property, you should know exactly who is showing up. Every one of our technicians is insured, background-checked, and uniformed. That means the work is covered, the person at your door is easy to identify, and you can feel comfortable whether you are home or not.
We also take working at height seriously. Our crews follow ladder and fall-safety practices in line with the OSHA ladder safety guidelines — because a professional should protect your home and themselves. It is the same commitment to standards championed by industry groups like the International Window Cleaning Association.
Photo-documented results and clear written quotes
We build trust by being specific. Before we start, you get a written quote that spells out the scope — not a vague “per window” number. During the job, our crews document problem areas like hard-water spotting, worn screens, or clogged downspouts so you can plan maintenance before small issues turn into expensive repairs. It is the same detail-first approach we describe in our guide on how to choose the best cleaning service in Chicago.
Booking that respects your time
You can book online through HouseCall Pro, call us, or request a quote from the website — whatever is easiest. We confirm arrival windows by text or phone so you are not stuck waiting all day. Same-day and next-day appointments are often available.
The Services We’re Known For
What started as window washing has grown into a full exterior-care menu for Chicagoland homes and businesses:
- Window cleaning — interior and exterior glass, screens, tracks, and skylights for a streak-free finish.
- Gutter cleaning — full clear-outs and downspout flushing to prevent water damage and ice dams.
- Power washing — siding, driveways, patios, and decks brought back to life.
- Solar panel cleaning — safe cleaning that restores lost energy output.
- Ice dam removal — steam-based removal that protects your roof through Chicago winters.
- Commercial cleaning — storefronts, offices, and managed properties on a schedule.

Rated 5 Stars Across Chicagoland
We would rather let our customers do the talking. Across our locations we hold 100+ five-star reviews with ratings of 4.9–5.0 on Yelp, Thumbtack, and Angi, plus Google. Customers consistently mention the same things: on-time crews, careful work around landscaping and furniture, and results that actually last.
That reputation is the reason we can say we are one of the top-rated window cleaning companies in Chicagoland — it was earned one job at a time.
Local Roots: The Suburbs We Serve
Being local is not just marketing for us — it shapes how we work. Our crews already know western-suburb parking rules, North Shore HOA scheduling, and how lake-effect weather affects glass and gutters. From our three offices we regularly serve Buffalo Grove, Arlington Heights, Northbrook, Wilmette, Winnetka, Highland Park, Deerfield, Libertyville, Lake Forest, Lombard, Elmhurst, Oak Brook, Downers Grove, and many more.
