Window Cleaning
in Charleston, SC

Clean windows change how a home feels more than almost any other exterior service. Light comes in brighter, rooms feel larger, and the views that make Charleston living worth it are actually visible. But keeping windows clean here is harder than it is almost anywhere else in the country — and that's not an exaggeration.

Window cleaning is a different discipline from pressure washing or power washing. Glass is cleaned with a pole-fed soft-bristle system and pure water on the exterior, plus traditional squeegee-and-solution work on the interior — never high-pressure force, which would void warranties on energy glass and risk cracking the panes outright. If you have been searching for 'power washing near me' to clean windows, what you actually need is professional window cleaning with purified-water final rinse for that spot-free finish.

Why Charleston Windows Get Dirty So Fast

Three things work against Charleston windows year-round. Salt air from the Atlantic deposits a fine mineral film on every exterior surface, especially on homes within a few miles of the coast — Sullivan's Island, IOP, Folly Beach, Kiawah, and downtown are all heavily affected. Spartina and oak pollen coats glass every spring, bonding to surfaces in a way that simple window cleaner barely touches. And the Lowcountry's high humidity means any residue that lands on glass stays wet long enough to stain or etch over time.

On top of that, most Charleston homes have full-screen storm windows or high-performance energy glass, both of which show streaks and water spots far more visibly than older single-pane glass. The combination of aggressive environmental load and unforgiving modern glass is why professional window cleaning pays for itself quickly.

Exterior Window Cleaning: Pure-Water-Fed Pole, No Streaks

Exterior window cleaning is where the salt haze, pollen, and storm residue actually live in Charleston. Our exterior method uses a water-fed pole system with reverse-osmosis and deionization filters that strip 99.9 percent of dissolved minerals out of the water before it ever touches your glass. Tap water contains calcium, magnesium, and iron — minerals that leave visible spots when water evaporates, no matter how clean the cleaning solution was. Purified water leaves nothing behind. The pole reaches up to 40 feet from the ground, so most second-story exterior windows on Charleston homes are accessible without ladders. The same purified-water system is what we use for solar panel cleaning on rooftop arrays — the chemistry is identical, the application is just adapted to vertical glass.

Exterior cleaning includes screen removal and washing on every visit (no upcharge), track vacuuming and wipe-down at every accessible window, and a final inspection from inside to confirm there are no missed streaks. We schedule exterior visits in dry weather windows whenever possible — Charleston pollen season (April and May) and post-tropical-storm cleanup are the two peak demand windows.

Interior Window Cleaning: Squeegee, Drop Cloth, Hand Detail

Interior window cleaning uses traditional squeegee-and-solution hand cleaning, because spot-free purified water matters less indoors and you can't realistically run a pure-water pole inside a home. Interior work takes more time but produces beautiful clarity. We move furniture away from windows as needed, use clean drop cloths on sills and floors to protect trim and flooring, and hand-detail every pane edge so the corners don't show the leftover film that DIY cleaning always leaves behind. Interior-accessible skylight glass gets wiped down on the same visit — but for any skylight that needs exterior rooftop cleaning, see our dedicated skylight cleaning service (different access requirements and chemistry).

Most clients book interior + exterior together as a complete package because the exterior work won't reach its full visual impact until the interior glass is also clean — dirt on either surface shows from both sides. Our combined interior + exterior service is priced lower than booking the two separately because the visit is one mobilization, not two.

Hard Water Stain Restoration

Hard water stains from irrigation overspray are the single hardest window-cleaning problem in Charleston. The white cloudy patches you see on the bottom third of first-floor windows facing your sprinkler heads are minerals that have actually etched into the glass surface — standard window cleaning won't remove them because the minerals are bonded at a microscopic level. We treat them with a specialized glass restoration compound that chemically dissolves the mineral bond, then polish the glass back to clarity. Hard water stain restoration is priced separately from standard cleaning (the technique takes longer per window) but most homes only have stains on a handful of lower windows, so the add-on charge is typically modest.

Once we restore stained glass, the best long-term fix is to redirect the irrigation heads — we'll show you which heads are causing the problem during the cleaning visit. Otherwise the stains return within a season. With irrigation redirected, twice-yearly cleaning prevents new etching from ever forming.

Screens and Tracks — Where the Dirt Actually Lives

Any real window cleaning includes screens and tracks. Screens accumulate pollen, salt, and spider webs so thickly that they can reduce airflow through your house by 30% — pulling them out and properly washing each one makes a visible difference. Tracks (the channels at the bottom of window frames) are typically full of dead insects, pollen, and sometimes even small plant debris. We vacuum every track before wiping it down so the window closes properly and your sills stay clean.

If your lower windows have hard water stains from irrigation overspray — usually showing as white streaks or cloudy patches on the bottom third of first-floor glass — we can treat those as an add-on. Once irrigation has actually etched glass the repair takes a dedicated restoration compound and hand polish, but it's much cheaper than replacing the glass itself. Twice-yearly cleaning prevents irrigation etching from ever becoming a problem.
