Window Washing & Gutter Cleaning That Lasts Twice As Long
A clean exterior is one of your property’s best assets, and it starts with your windows. Window Gang of St Louis serves residential and commercial properties throughout St. Louis with Window Washing, Gutter Cleaning, Pressure Washing, Soft Wash, and Dryer Vent Cleaning. We clean the full exterior, from sidewalks and driveways to fences and siding, so your property looks its best.
Our proprietary Window Gang Blue solution is what sets our window cleaning apart. The wash and wax formula cleans and waxes glass in one step, creating a non-stick wax barrier that repels dust and debris and keeps windows cleaner for up to two times longer than standard solutions.
Window Gang Blue contains no ammonia-based chemicals. It’s also biodegradable, so it’s gentle on your landscaping and the surrounding environment. You get a thorough, lasting clean without any of the trade-offs.
Full-Service Exterior Cleaning for High Ridge Homes & Businesses
Window Washing is where we start, but it’s far from where we stop. Window Gang of St Louis handles exterior cleaning for homeowners and commercial facility managers throughout St. Louis. We coordinate the work so you don’t have to manage multiple contractors for one property.
Pressure Washing & Soft Washing
Our Pressure Washing works well on concrete surfaces such as driveways and sidewalks, while Soft Wash uses lower pressure to protect siding and other surfaces sensitive to high-force methods. You get one crew and one upfront estimate with no surprise fees.
What to Expect from Our Technicians
Every technician who arrives at your St. Louis property is uniformed, background-checked, fully licensed, bonded, insured, and on schedule. Before starting, our technicians introduce themselves and walk you through the planned work. We protect floors with shoe covers before any interior work begins and leave the property cleaner than we found it.
Our window washing service covers windows inside and out, including the frames and sills, for single-family homes, condos, and townhomes. We also clean storefront and office-building windows for commercial properties.
Our 7-day service quality guarantee covers work issues noticed after service. Report the issue within seven days, and we’ll return to address it. The All Shine, No Shakedown Guarantee also means transparent recommendations without hard-sell add-ons.
What Happens After You Request a Free Estimate
We begin by reviewing the exterior cleaning services you need and providing pricing before work begins. You’ll know the scope before our technicians start.
Here’s what to expect:
Request an estimate: Tell us whether you need Window Washing, Gutter Cleaning, Pressure Washing, Soft Wash, Dryer Vent Cleaning, or coordinated services.
Review the work: Our technicians introduce themselves and walk you through the planned service before getting started.
Check the results: If you notice a work issue after service, report it within seven days under our service quality guarantee.
St. Louis properties include single-family homes, condos, townhomes, storefronts, and office buildings, each with different exterior cleaning needs. Window Gang of St Louis has the tools and solutions to clean windows, gutters, siding, concrete, and other exterior surfaces for residential and commercial customers.
Local Owners with National Standards
As part of America’s #1 window washing franchise, with over 35 years of experience behind us, we have access to proven resources and techniques. We’re also a locally owned and operated business, so your service is backed by neighbors who understand St. Louis properties and care about getting it right. Our technicians are fully licensed, bonded, and insured, so you can trust us to treat your property like our own.
Window Washing Frequency in St. Louis
Pollen, airborne debris, and moisture leave film on exterior glass, window frames, and sills over time. Regular maintenance removes routine surface dirt before it continues building up on the windows and adjacent surfaces.
Most homeowners in the St. Louis area benefit from professional Window Washing two to four times per year. The right frequency depends on the property, surrounding conditions, and how quickly residue becomes visible.
Get More Than Just Clean Windows
When you work with Window Gang of St Louis, you get more than sparkling windows. Our team takes time to answer your questions, offers honest maintenance advice, and leaves your property in better shape than we found it.
And with our All Shine, No Shakedown Guarantee, you can rely on:
No high-pressure upselling because we treat every client like family.
A 7-day service quality guarantee for work issues reported after service.
No messes left behind thanks to our well-maintained fleet and protective footwear.
A thorough employee screening process that supports your safety and peace of mind.
Whether you need window and gutter cleaning, Pressure Washing, Soft Wash, or another one of our services, we’re your all-in-one exterior cleaning solution for St. Louis.
Cleaning Glass, Frames, Sills & Screens
Professional window cleaning involves more than removing visible residue from the center of each pane. We clean windows inside and out, along with frames and sills, to address the dust and debris that collect around them.
Screens are available as an additional cleaning service. Because screens, tracks, sills, and frames have different cleaning needs, confirm the requested scope when discussing your estimate rather than assuming every adjacent component is included.
Hard Water Spots & Mineral Deposits
Routine cleaning addresses water-soluble dirt and debris, while hard water deposits and other persistent stains require different treatment. Mineral deposits become more difficult to remove the longer they remain on the glass.
Paint, concrete residue, hard water stains, and similar deposits must be approached with appropriate methods. Improper removal can damage glass, coatings, or adjacent metal frames, so these conditions should be identified before cleaning begins.
Clean Windows & Natural Light
Daylighting is the use of windows and skylights to bring natural light into a building and help regulate indoor temperatures. Using available daylight can reduce reliance on artificial lighting, while strategic daylighting also plays a role in overall heating and cooling needs.
Clean glass supports clearer views and allows more natural light into interior spaces than glass obscured by surface film. Actual energy use depends on the building, window placement, glazing, and how occupants use the space.
We don't just wash off the dirt—we protect your glass. Using professional-grade, eco-friendly formulas, our deep-cleaning process leaves your windows streak-free and repels dust and grime long after we leave.
No Mess Left Behind
While our work shines, our presence doesn't linger. We leave no trace behind.

Wow! I can't believe the difference.
As a real estate agent, I know how impactful clean windows can be to a property. As a homeowner of a little weekend woodland lake cottage, though? Wow! I can't believe the difference. Thank you, thank you. It will definitely help the house show better and improve the beautiful view of the forest and lake outside of our house. I can't wait to use you guys again in business and personal. 100% well worth the expense.

Windows Truly Clean and Spotless
I am excited to update a review I gave the other day. I had some issues with the original window cleaning done at my house, and Window Gang was quick to respond and address the issue. Within 24 hours, the windows are now truly clean and spotless. I spoke with someone at their office twice and feel great about the company's communication and promise to do good work. I would hire them again.

I Will Use Them Again
First time using Window Gang on 6/2026 and wasn't sure of using to clean house siding. Took my chance then after he was done, looked great after going back over some missed areas the next day. Price was reasonable, of course, based on how big house is and anything extra. I will use them again providing affordable pricing. 5 star because of good price for me and 7 day guarantee and made good on coming back out.
Gary Manyblessings
