Window Cleaning Services

Clear glass that makes the right first impression

Streak-free interior and exterior window cleaning for offices, storefronts, and new construction throughout Appleton and the Fox Cities, from ground-floor entrances to upper-story windows.

Commercial Window Cleaning Services in Appleton & Fox Cities, WI

Windows get dirty slowly, so it's easy to stop noticing. Dust, pollen, rain spots, fingerprints on the entry doors, and in Wisconsin, a winter's worth of road salt and slush spray. Your customers, tenants, and visitors notice it the moment they walk up to the building.

We provide commercial window cleaning for offices, multi-tenant buildings, storefronts, restaurants, and construction projects across Appleton, the Fox Cities, Oshkosh, and Green Bay. That includes exterior windows, interior glass, frames, sills, tracks, and screens.

Because we're a commercial cleaning company, windows don't have to be a separate vendor. We can clean the glass inside and out, and fit it into the cleaning your building already needs.

Clean Windows Say More Than You Think

People judge a business before they walk through the door. Clean glass lets in more natural light, shows off your space, and tells visitors the building is cared for. Hazy, spotted windows say the opposite, even when everything inside is spotless.

The problem is that regular wiping doesn't fix it. Household glass cleaner and paper towels move dirt around and leave streaks, especially on large panes. Professional window cleaning uses the right solution, squeegee technique, and detail work on frames and sills to get glass truly clear, and to keep it that way longer.

Exterior Window Cleaning for Multi-Story Buildings

Exterior glass takes the most abuse: rain, dust, pollen, bird droppings, and in the Fox Cities, road salt in winter and the lake fly hatch around Lake Winnebago every spring.

We clean exterior windows on single-story storefronts and multi-story office buildings. Ground-level and low windows are cleaned by hand, and for upper floors and hard-to-reach glass we bring in lifts, so height doesn't limit which buildings we can serve.

Every exterior clean includes the glass, plus a wipe-down of frames and sills so dirty water doesn't run back onto clean windows at the next rain.

Interior Glass, Skylights & High Windows

Inside glass gets touched, leaned on, and smudged all day. Glass entry doors, office partitions, conference rooms, and display cases show fingerprints faster than almost any other surface in a building.

We clean interior windows and glass along with frames, sills, and tracks, where dust and dead insects collect. For skylights, atriums, and high lobby windows, we use lifts to reach glass that usually gets skipped for years.

If we already clean your building, interior glass can simply be added to your regular service.

Post-Construction Window Cleaning

New windows usually arrive at the end of a project covered in labels, paint overspray, drywall dust, caulk, and adhesive. Getting that off without damaging brand-new glass takes more care than a regular clean.

Some tempered and coated glass scratches easily when it's scraped the wrong way. We check the type of glass first, choose the method that fits it, and talk it through with you before we start. We clean frames, sills, and tracks too, so the building is ready for inspections, owner walkthroughs, and occupancy.

Good to know: The International Window Cleaning Association (IWCA) publishes guidance on cleaning new construction glass, including why glass should be protected during construction. Learn more:

Recurring Window Cleaning Schedules

The easiest way to keep windows looking good is to never let them get bad. A regular schedule costs less per visit than a heavy clean every few years, and your building always looks cared for.
How often depends on your building and how many people see it every day:

Building Type	Typical Starting Schedule
Restaurants and storefronts	Exterior every 2–4 weeks, entry glass more often
Offices and medical buildings	Exterior quarterly, entry doors and interior glass monthly
Multi-tenant and multi-story buildings	2–4 times per year
Warehouses and industrial buildings	1–2 times per year

We'll recommend a schedule after seeing your building, and you can adjust it anytime.
Many businesses also add an extra clean after the spring lake fly hatch or once road salt season ends.

Frequently Asked Questions

Do you clean both interior and exterior windows?

Yes. We clean exterior windows, interior glass, glass doors and partitions, and frames, sills, tracks, and screens. You can book both sides together or just one.

Can you clean windows on multi-story buildings?

Yes. We clean ground-level and low windows by hand and use lifts for upper floors, skylights, and high interior glass. Tell us about your building and we’ll plan the right approach.

Do you clean windows in the winter?

Yes, year-round, weather permitting. Exterior work depends on temperature and wind that day, and interior glass can be cleaned anytime. Winter is often when storefronts need it most, because road salt and slush spray build up on entry glass fast.

How often should commercial windows be cleaned?

It depends on the building. Storefronts and restaurants usually need exterior cleaning every 2–4 weeks, offices quarterly, and larger or industrial buildings a few times a year. We’ll recommend a schedule after seeing your building.

Can window cleaning be added to our regular janitorial service?

Yes. If we already clean your building, interior glass and scheduled exterior cleaning can be added to your existing service, with one contact and one invoice.

Do you clean windows for homes?

Our focus is commercial buildings, but we do take on larger residential window cleaning projects. Send us a few details and we’ll let you know if it’s a good fit.

Do you serve areas outside Appleton?

Yes. We serve Appleton, Neenah, Menasha, Kaukauna, and the surrounding Fox Cities, along with Oshkosh and Green Bay.
