Glass three blocks from the Atlantic does not get dirty the way glass inland does. On a Surfside Beach cottage the film that dulls a pane is mostly salt, carried in on the onshore breeze as an aerosol fine enough that you never see it land. Salt is hygroscopic - it pulls moisture out of the humid air and stays faintly damp - and damp salt grabs everything else moving through that air: quartz sand lifted off the dunes, pine and oak pollen in April, road grit off Ocean Boulevard. That is why a window here can look hazy a month after it was cleaned while the same window in Conway still looks fine, and it is why dry-wiping is the single worst thing you can do to it. Dragging a cloth across a dry salt-and-sand film is dragging abrasive across glass.
Why we flood the glass before anything touches it
Every pane gets soaked and rinsed before a squeegee, a scrubber or a hand ever comes near it. The flood is not cosmetic - it is what floats the sand off the surface so the pass that follows is cleaning glass instead of sanding it. On the seaward elevations we usually rinse twice, because the first pass mostly just dissolves the salt crust and the grit underneath only lets go once that binder is gone.
The other reason the order matters is heat. A south or west pane in July is hot enough to flash a cleaning solution dry in seconds, and solution that dries on the glass leaves its own residue on top of the salt you were trying to remove. We work those elevations early, or we work them in the shade side of the house first and come back, rather than fighting a pane that is drying faster than it can be squeegeed.
Screens and tracks are where the actual work is on a beach cottage
Most people book window cleaning because of the glass and get the biggest visible change out of the screens. Screen mesh on the coast greys out faster than anything else on the house - the weave holds salt on every strand, and once it is loaded the screen reads as a dull sheet from inside even when the pane behind it is spotless. Cleaning the glass and reinstalling a grey screen over it is why some jobs look barely different from the street. We pull screens, wash them flat, rinse them, and let them drain before they go back.
Tracks are the other half. Sliding door and window tracks on an oceanfront lot fill with sand, and sand plus salt plus condensation turns into a packed grey paste that seizes rollers and holds water against the frame. It gets vacuumed out and flushed rather than wiped over, because a wiped track just redistributes the paste into the corners where it does the damage.
Irrigation spotting on the landward side, and where mineral becomes permanent
Not every mark here is salt. On the streets set back from the beach - and on the landward elevations of houses that are on it - the ground-floor glass is usually being hit by lawn irrigation. Heads that throw across the beds beside a wall catch the same panes on every cycle, and Horry County groundwater carries enough dissolved mineral that each cycle leaves a ring behind when it dries on a hot pane.
Caught early that is a cleaning problem and it comes off. Left through two or three summers it is not. Mineral that has been baked onto glass repeatedly bonds into the surface and eventually etches it, and etched glass is a physical change in the pane, not a deposit sitting on top of it. No chemical, no amount of scrubbing and no restoration polish we would be willing to put on a residential window brings that back. When we see it we say so on the walk, clean everything that will actually clean, and tell you plainly that the haze remaining on those two ground-floor panes is in the glass.
The other honest limits, said before we quote rather than after
A fogged or cloudy double pane that stays cloudy after cleaning is a failed seal. The moisture is between the two panes, the unit is sealed, and no exterior or interior cleaning reaches it - that is a glazing replacement, and we will point you at it rather than charge you to clean around it. Scratches from a previous dry-wipe, or from a contractor scraping paint off a tempered pane, are also permanent, and tempered glass in particular can carry fabrication debris that will scratch under a blade, so we do not blade tempered units.
On height, we clean what we can reach safely from the ground and from ladder work on a normal two-story cottage. We are not a high-rise crew, so an oceanfront tower unit above that is not our job. And we do not remove and reinstall storm panels or accordion shutters - if they are closed over the glass on the day, that elevation gets skipped and is not billed.
Working around Saturday changeover on the rental blocks
A large share of the houses on these streets turn over weekly, and on the Surfside and Garden City blocks that changeover is Saturday. Trying to clean glass on a Saturday between one guest leaving and the next arriving is how a crew ends up rushed, half-finished, or standing in a driveway full of cars. For rental property we schedule mid-week where we can, and where a Saturday is genuinely the only gap we scope it small and honestly - the seaward elevations and the sliders, not the whole envelope.
If you manage several units on one street, say so when you book. Doing four houses on the same block in one visit is materially cheaper for us to run than four separate trips, and that shows up in the quote rather than disappearing into it.
The two windows worth booking, and what the day looks like
The two natural times are late spring, after the pine and oak pollen has finished falling and stuck itself to every salt-damp pane, and early autumn, after the summer of hot sun, daily irrigation and heavy rental traffic. Booking straight into the middle of pollen season is spending money on a result that will not last three weeks. On a permanently exposed oceanfront elevation, twice a year is realistic; on the landward side of a set-back house, once is usually enough.
On the day we walk the house with you first, flag anything that is etched, scratched or seal-failed before we start so there are no surprises at the end, pull and wash screens, flood and clean the glass, detail the tracks and sills, and rinse down what the run-off touched. You get a look at the finished elevations before we leave.
Soft washing and window cleaning are not the same service. Glass work is what is on this page: salt-spotted panes, tracks, sills, and the screens that grey out first on an oceanfront cottage. Soft washing is the low-pressure detergent method we use on the surfaces around the glass, siding, trim, soffits, and porch framing, where the humid ocean air keeps mildew working on every shaded wall. If what you actually want is the whole exterior brought back rather than the glass alone, start with soft washing in Surfside Beach. The two pair naturally, because a soft wash rinses dirty run-off down the walls and over the glass, so the windows are best done last, in the same visit.
