Exterior Window Cleaning in Charleston, SC
Streak-free exterior glass for Charleston homes — including the multi-story and waterfront properties where salt film builds fastest. Clean windows change how a whole house feels, inside and out, and they are one of the easiest services to bundle with a house wash.
What coastal living does to your glass
You notice it most in the morning light: a haze on the glass that will not wipe away from the inside, water spots that came back a week after you cleaned them, and a view of the marsh or the water that is just slightly duller than it should be. That is Charleston at work. Salt carried on the sea breeze settles on exterior glass and dries into a fine mineral film. Pollen season coats everything in yellow. Sprinklers and storms leave hard-water spotting. Rain rinses off dust, but it does not remove salt film — in many cases it makes the spotting worse.
On waterfront and island homes, this cycle runs fast. Glass that faces the water can start to haze again within weeks of a cleaning, which is why many of our coastal customers put their windows on a regular schedule rather than waiting until the view bothers them.
What this service covers
- Exterior glass on all elevations
- Multi-story and elevated coastal homes
- Salt film and coastal haze removal
- Pollen and organic grime removal
- Streak-free finishing on every pane
- Condition check of glass before we start
Made for multi-story and waterfront homes
A lot of window cleaning around Charleston is straightforward one-story work. Ours often is not. Elevated construction, third- and fourth-story glass, and big water-facing window walls are normal on the islands, and they are exactly the windows homeowners cannot safely reach themselves. If your home is tall, raised, or right on the water, tell us when you request a quote — that is the work this service was built around.
The easiest upgrade to a house wash
Most customers book exterior window cleaning together with a house wash, and the order matters: we wash the home first so grime from siding and trim is gone, then finish the glass so nothing above it can streak back down. One visit, one crew that already knows your property, and the entire exterior — siding, trim, and glass — is done at the same time. If your windows sit above a porch or deck, pairing the services also means every surface around the glass gets the same careful treatment.
How we approach your windows
- Walk and inspect We look at every window first — glass condition, seals, height, and access — and flag anything pre-existing before we begin.
- Remove the buildup Salt film, pollen, and organic grime are broken down and lifted off the glass with a gentle, non-abrasive process, never scraped or forced.
- Streak-free finish Each pane is finished so it dries clear, without the streaks and re-deposited film that quick hose-downs leave behind.
- Final check in the light Glass hides its flaws until the sun hits it, so we re-check panes from the angles that show streaks and touch up anything that needs it.
- Photos if you are away If you are not home, we send photos of the finished work so you can see the result before we leave the driveway.

Exterior window cleaning FAQ
- Why do my windows look hazy even after rain?
- Near the coast, salt carried on the breeze settles on glass and dries into a fine film that rain alone does not rinse away. Add pollen, dust, and hard-water spotting from sprinklers, and glass slowly loses its clarity. Proper exterior cleaning removes that buildup instead of just moving it around.
- How often should exterior windows be cleaned in Charleston?
- It depends on how close you are to the water. Waterfront and island homes often benefit from cleaning several times a year because salt film returns quickly. Homes further inland usually stay clear with one or two cleanings a year, often timed with a house wash.
- Can you reach windows on a three- or four-story home?
- Yes. Multi-story coastal homes are a regular part of our work around Charleston and the islands. Mention the height of your home when you request a quote and we will plan the job accordingly.
- Will the cleaning scratch or damage my glass?
- No. We use a gentle, non-abrasive process and check the condition of the glass before we start. If we spot anything unusual, like damaged seals or existing scratches, we point it out before work begins.
- Can I bundle window cleaning with a house wash?
- Yes, and it is the most popular way to book this service. Washing the house first removes the grime above the glass, then the windows are finished so the whole exterior is done in one visit.
- Do you clean the inside of the windows too?
- This service covers the exterior side of your glass, which is where Charleston's salt, pollen, and grime build up. If you have questions about anything beyond exterior glass, just ask when you request your quote.
- Do I need to be home during the service?
- No. As long as we can reach the exterior of the home and any gated areas, we can complete the work while you are out and send photos of the finished result.
