Window cleaning covers more than a squeegee and a bucket. Most West Columbia crews handle exterior and interior glass, screens, tracks and sills, and on older homes near the river and downtown, storm windows that need to come apart before they can be cleaned properly. Second-story and higher work usually means extension poles with water-fed brushes, or in some cases ladders, so ask upfront how a company reaches upper floors and whether that affects the price. Commercial jobs, like storefronts along State Street or office buildings, often get added to a recurring schedule instead of a one-time visit.
When you're comparing companies, look past the price quote. Ask whether they carry liability insurance, how they handle screens and hard water spots (common in this area from sprinklers and mineral-heavy water), and whether they guarantee a redo if streaks show up after drying. A crew that inspects frames and reports loose caulking or cracked panes while they work is usually paying closer attention than one that just wipes glass and leaves.
