Why Choose CleanPro for Your Commercial Window Cleaning in St. Louis?

Window cleaning has a special place in our hearts. Our owner-operator Nick Giordano started CleanPro in 2012 as a window cleaning business, working as a one-man crew with nothing more than a squeegee and a bucket.

Here's what makes our window cleaning services stand out:

Built on Window Cleaning Expertise

Unlike general contractors who “also do windows,” CleanPro has specialized in window washing from day one. Our team knows how to deal with the kinds of buildup commercial windows face in St. Louis: airborne pollution, hard water spots, pollen, dust, and bird droppings. We believe every job worth doing is worth doing well, and we pay just as much attention to your windows as any other part of your property's exterior.

Streak-Free Results on Low-, Mid-, and High-Rise Buildings

We use a professional water-fed pole system that allows us to safely clean exterior windows up to three stories high from the ground, and we have ladders, boom lifts, and cranes for taller buildings. Purified, filtered water and a spot-free rinse keep minerals and sediment from drying on the glass, so your windows stay cleaner and clearer for longer and don’t develop the chalky haze you get from hose water or store-bought spray.

Safe, Eco-Friendly Cleaning Solutions

All of our cleaning solutions are non-caustic and biodegradable, so you don’t have to worry about damage to landscaping, entry areas, or sensitive exterior materials. We pair those detergents with proven techniques to remove contaminants without scratching glass, harming frames, or leaving behind sticky residue that attracts dirt.

Commercial Scheduling That Fits Your Operations

CleanPro is built around commercial needs. We offer flexible, stress-free scheduling and work with many businesses on monthly, quarterly, or annual service plans so windows stay consistently clean without you having to remember to call. Our crews can work around your busiest times to minimize disruption for tenants, employees, and customers.

Local, Fully Insured, and Focused on Service

As a locally owned St. Louis company, our number one goal is to make St. Louis the cleanest place to live and work. Our technicians are highly trained, our equipment and methods are industry-approved, and your satisfaction is fully guaranteed. We treat your property with the same care and attention we’d want for our own.

While our business started with window washing, we've since expanded to offer a full suite of commercial cleaning services to St. Louis businesses of all types.

Why Your St. Louis Business Needs Window Cleaning

Clean windows give off a more professional impression to customers/tenants, create a healthier, more productive working environment, help your property be more energy-efficient, and protect one of your building's more important assets.

• Windows are front and center at any property. Clean, streak-free glass highlights your attention to detail and reflects the pride you take in your property. With clean windows, customers naturally assume that the same professionalism carries into your building and the services you provide. For apartment buildings and condos, clean windows help boost tenant satisfaction, making people more likely to sign or renew their lease.
• Conversely, dirty or hazy windows can make a building look neglected, undermining confidence in your services even if everything inside is spotless and well-run.
• Clean windows improve natural light. This is a huge benefit to businesses and property managers for a few reasons:
  • Employees are happier. By letting in more natural light, clean windows reduce eye strain, lift moods, and foster increased productivity.
  • By maximizing natural light, your building becomes more energy efficient. More daylight means less energy spent on artificial light. More solar heat reduces heating demand in colder seasons; in warmer weather, clean windows allow your blinds to work more effectively, reducing cooling needs. Insulation around windows won't deteriorate.
  • Customers and tenants each have a better experience inside and are more likely to return or renew.
• Clean windows extend the windows' lifespan. Contaminants from hard water, mineral deposits, rain, and pollution can etch into glass over time, potentially requiring a replacement.
• Moisture and grime collect around window frames, sills, and coatings, leading to additional repairs if the windows aren't professionally cleaned.

How Often Should I Get My Business's Windows Cleaned in St. Louis?

Some exterior surfaces, like building sides or concrete in parking lots, might only need to be cleaned once a year. But windows get dirty much faster and show streaks, smudges, and buildup long before other surfaces do. While every property is different, some general guidelines are:

• Retail, Storefront, & Strip Malls: Monthly, or as often as two to four weeks.
• Restaurants & Cafes: Monthly, or as often as two to four weeks.
• Office Buildings: Every 1-3 months; entries monthly.
• Healthcare Facilities: Monthly to bi‑monthly; high‑visibility entries every 4–6 weeks.
• Schools & Universities: Quarterly; main entrances and lobbies every 1–2 months.
• Hotels & Hospitality: Monthly to every 6–8 weeks; lobby/front facade more frequently.
• Car Dealerships: Every 2–4 weeks due to glass showrooms and road grime.
• High-Rise Commercial Building: Every 2–4 months overall; ground‑level glass more frequently.
• Apartment Buildings & Condos: 2–4 times per year; leasing office and entrance monthly.
• Drive‑Thrus & Quick‑Serve Fronts: Every 2–4 weeks; menu boards and order windows as needed.
• Stadiums & Arenas: Before each major event season and at least quarterly.
• Industrial & Manufacturing Facilities: Every 3–6 months.
