Exterior Cleaning Services in St. Louis, MO

Windows, Gutters, Pressure Washing & More from One Local Team

Window Gang of St Louis is a locally owned and operated exterior cleaning company serving St. Louis, MO homeowners and commercial facility managers, including communities across Ballwin, Chesterfield, Jefferson County, and O’Fallon. We handle every surface on the outside of your property: windows, gutters, driveways, siding, dryer vents, and seasonal holiday lighting. Our technicians are fully licensed, bonded, and insured, and they live in the same communities they serve.

St. Louis summers bring heavy pollen, humidity, and storm runoff that leave windows streaked, gutters packed, and siding stained well before autumn arrives. Coordinating multiple single-service companies to address all of it costs time and invites scheduling headaches. One crew, one call, and one consistent standard is a simpler path to a clean exterior.

Our Exterior Cleaning Services

We offer six services designed to cover every exterior surface a St. Louis property faces, each matched to the surface type and the specific demands of our regional climate.

Window Washing
We clean interior and exterior glass using our proprietary Window Gang Blue wash-and-wax formula, leaving a streak-free finish that also deposits a protective wax coating so windows can stay cleaner up to twice as long as standard methods.

Gutter Cleaning
Our Gutter Cleaning service removes debris and flushes downspouts to keep water moving away from your roofline and foundation. Left unaddressed, clogged gutters can cause fascia damage, water intrusion, and erosion. For properties that need consistent upkeep, a quarterly maintenance plan with four visits per year is available.

Pressure Washing
High-pressure cleaning is the right tool for hard surfaces: driveways, sidewalks, decks, fences, and siding built to handle it. We use pressure washing where the surface calls for it and switch methods when it doesn’t.

Soft Washing
Delicate surfaces like roofing, painted wood, and vinyl siding need a gentler approach. Soft washing uses low-pressure application with solutions scaled to the material, removing mold, mildew, and algae without the risk of damage that high pressure can cause.

Dryer Vent Cleaning
Lint buildup in dryer vents is one of the leading causes of household fires, and it’s easy to miss with routine home maintenance. Our dryer vent cleaning service clears that accumulation professionally, helping reduce risk where it matters most.

Holiday Lighting Services
We offer holiday lighting installation and removal for residential and commercial properties throughout the area. Custom design, installation, and takedown are all handled by our team, so you don’t have to go up a ladder.

Window Gang Blue: Cleaner Glass, Longer

Every window washing we perform uses Window Gang Blue, our proprietary biodegradable wash-and-wax formula. Most cleaning solutions wash the glass and stop there. Window Gang Blue goes further: it deposits a non-stick wax coating that helps prevent dust and debris from settling back onto the surface, which is why our results can last up to twice as long as a standard cleaning.

The formula contains no ammonia, which matters because ammonia degrades window films and seals over repeated use. It’s also formulated to protect landscaping and avoid runoff risks, so the cleaning process doesn’t trade clean windows for damaged flower beds or compromised drainage.

What to Expect from Every Visit

Our standards are consistent across every job. Uniformed, background-checked technicians arrive on schedule in well-maintained vehicles. Before entering your home, they put on shoe covers to protect your floors. Every job starts with an up-front estimate so there are no surprise charges when the work is done.

We back all of our work with the All Shine, No Shakedown Guarantee: no high-pressure upselling, no unnecessary add-ons, and no mess left behind. If there’s something else your property could use, we’ll mention it once and let you decide. Our goal is to complete the job right in one visit and leave your property cleaner than we found it.

Local Ownership, National-Caliber Training

As part of the national Window Gang franchise system, recognized on the Entrepreneur Franchise 500 list from 2018 through 2024, our St. Louis location has access to national-level training, equipment, and proprietary products. That structure gives our team tools and processes many independent operators don’t have. Local ownership means those resources are applied by people who understand St. Louis weather patterns, building materials, and what a Mississippi River climate does to exterior surfaces across the seasons. We serve a broad footprint from Ballwin and Chesterfield to Jefferson County, O’Fallon, and dozens of additional communities throughout the region.
