The haze on your exterior glass usually isn’t dirt you can wipe off. It’s a thin mineral-and-organic film that builds up in layers, and wiping it with soap and water mostly just moves it around. That grime doesn’t just settle on siding. It builds into a thin film on your exterior glass that dulls the view and leaves windows looking hazy no matter how recently you wiped them down.
We handle that film a different way, cleaning exterior glass with pure-water technology instead of soap and a squeegee. A water-fed pole carries filtered water up to the glass, and because that water dries without leaving mineral spots, every window finishes clear. The reach lets our team clean most of a home from the ground, so cleaning your windows doesn’t mean ladders leaning against your siding. It’s one of the simplest ways to keep a home looking cared for here.

Our pure-water method works across the common window styles found on Summerville homes, from the standard double-hung windows on most houses to the large fixed-pane glass that makes a room.
Storm windows get the same treatment on the outer glass; if yours are the removable kind, take them off with the screens and we’ll clean both. We wet each sash and the glass, scrub, and rinse with pure water so the whole window dries without spots or streaks.
Large sliding-door glass gets cleaned the same pure-water way. The bigger panes take a little longer to work across, and they come out just as clear.
The multi-panel angled glass of a bay window is reached and cleaned pane by pane, from the ground wherever the height allows.
Big picture and fixed-pane windows are where water spots and film show up the most, and where an uninterrupted sheet of glass has nowhere to hide them. Pure water leaves nothing behind as it dries, which is exactly what glass this size needs.
There’s more to a clean window than a quick wipe, and a few things set our approach apart for this service specifically.

Because we clean from the ground with a water-fed pole, ladders stay off your siding and gutters during a standard clean, and there’s no soap film waiting to streak the next time it rains. What you get is glass that dries clear on its own, the way pure water leaves it. It’s the same deionized-water setup we use for solar panel cleaning, where a spot-free finish matters just as much.

Instead of hiring a separate window company, a gutter company, and a pressure washer, you get it all done in one visit, by one company, with one bill, while we’re already on site. Since we’re often at your home for a house wash anyway, adding window cleaning is simple, and the standalone window minimum falls away when it rides along with that wash.

We treat your property with care on every job. Pure-water window cleaning is gentle on landscaping and paint, and we work carefully around beds, fixtures, and entryways, so your glass comes out clear while everything around it stays exactly as it was.
You can call us or get an instant estimate online. We account for how many windows you have, their height and style, and whether it’s a standalone clean or part of a house wash, then provide a free estimate before anything gets scheduled.
Once you approve the estimate, we book the job and send confirmation along with reminders as the appointment gets closer. Because this is an exterior clean, we remind you two days and one day before to remove your window screens so we have full access to the glass.
We clean the exterior glass with a Xero water-fed pole and a deionized (DI) water tank. Each window is wet, scrubbed, and rinsed with pure water, and since the pole reaches up to about 40 feet, most homes are cleaned entirely from the ground.
When the glass is done, we walk the property with you to confirm every window is clean before any equipment gets packed up. Since we’re already reaching the upper part of the house, it’s also an easy time to look at your gutters if they need clearing. The invoice only follows once you’re satisfied, If something isn’t right, we come back and make it right — that’s our satisfaction guarantee.
Exterior window cleaning is priced per window, with a standalone minimum that goes away once it’s bundled with a house wash, which is why most homeowners simply add it to a wash they’re already booking.
We focus on the outside of the glass, where the Lowcountry weather does its work and where the difference shows most. It’s the most common question homeowners ask, so we like to set that expectation clearly up front, and the exterior clean is what brings back that just-washed look from the curb.
We clean with pure water instead of soap and a squeegee. The water runs through a deionizing filter that strips out the hard-water deposits that normally leave spots, and each window is wet, scrubbed, and rinsed with that pure water, so it dries clear with nothing left behind.
For most homes, no. Our water-fed pole reaches up to about 40 feet from the ground, so we clean the great majority of a home’s windows without a ladder ever touching your siding or gutters. It’s the same ground-based approach that keeps our crew off the roof during a roof cleaning, and it’s easier on your home.
When your Summerville home’s glass loses its clarity, we bring it back spot-free and leave your windows looking the way they should. Get a free estimate the way that suits you, instant online or by phone, then call the team at Holy City Hydroshine at (843) 729-3095 to book your window cleaning.
