Exterior Cleaning Services in Greenville, SC

We Clean More Than Glass

Window Gang of Greenville-Spartanburg is a locally owned exterior cleaning company serving Greenville, Spartanburg, Clemson, Simpsonville, Lake Keowee, and more than 80 communities across Upstate South Carolina. We handle every surface of your property’s exterior: windows, gutters, driveways, siding, dryer vents, and chimneys. One call, one team, every surface handled.

Upstate SC’s humid subtropical climate is hard on buildings. Pollen coats windows every spring, mold and mildew creep across siding, and rainwater stains work into concrete and brick. Left unchecked, that buildup doesn’t just hurt curb appeal. It can accelerate surface deterioration and affect property value.

Our Greenville-Spartanburg Services

We offer a complete lineup of exterior cleaning services for homes and businesses throughout the Upstate.

Window Washing
Our proprietary Window Gang Blue formula cleans and waxes glass in one step. It’s biodegradable, ammonia-free, and keeps windows cleaner twice as long as ordinary cleaning products. The result is a streak-free finish that lets more light in and helps glass stay cleaner longer.

Gutter Cleaning
We clear debris from gutters and flush downspouts so water can move away from your home the way it should. In a high-rainfall climate like ours, clogged gutters can cause fascia rot, foundation erosion, and water intrusion into basements and crawl spaces.

Pressure Washing
Driveways, sidewalks, fences, and hard exterior surfaces collect grime that regular rain won’t touch. Our Pressure Washing service removes built-up dirt and stains, restoring surfaces without damaging them.

Soft Wash
High pressure does more harm than good on siding, stucco, and other delicate materials. Soft Wash uses lower pressure combined with cleaning solutions formulated to eliminate mold, mildew, and algae at the source rather than just blasting the surface.

Dryer Vent Cleaning
Lint and debris accumulate inside dryer vent systems over time, and a clogged vent is a recognized fire risk. Annual Dryer Vent Cleaning removes that buildup, reduces fire hazard, and helps your dryer run more efficiently.

Chimney Sweep
Our Chimney Sweep service clears creosote, debris, and blockages to support safer fireplace operation. We’re available for both inspections and full cleanings.

Serving Residential & Commercial Properties

We work with homeowners, property managers, business owners, and facility managers throughout the Greenville-Spartanburg area. For residential customers, that means single-family homes and multi-story properties kept clean from roofline to driveway. For commercial clients, that means office buildings, retail storefronts, restaurants, and managed properties maintained to a professional standard.

Large-footprint properties benefit from having a single provider handle every exterior surface in one coordinated visit. Our commercial teams work around your operating schedule to keep disruption to a minimum.

The Difference Is Clear

The Window Gang brand has over 35 years of industry experience and has been named Entrepreneur magazine’s number one window washing franchise seven years running. As the locally owned Greenville-Spartanburg location, we bring that national system to your neighborhood with the added advantage of knowing Upstate SC’s specific conditions, weather patterns, and building materials firsthand.

Every technician on our team is uniformed, background-checked, and arrives on schedule. Before we step inside, we put on shoe covers. Our fleet is well maintained and won’t leave oil stains on your driveway. We’re fully licensed, bonded, and insured.

Our All Shine, No Shakedown Guarantee means no hard-sell upsells, no surprise fees, and no second visit to address what we should have done right the first time. We leave every property cleaner than we found it.
