Coastal conditions
Salt aerosol lands on Cape Fear glass every day the surf is up. Left long enough it stops being a film you can wash and becomes damage in the glass itself.
The mechanism
Breaking waves throw fine droplets into the air. The water evaporates on the way inland and leaves a salt particle small enough to travel on an ordinary sea breeze. On Wrightsville Beach that happens every day the surf is running, which is most of them.
A pane facing east starts collecting the moment it is cleaned. You do not see it at first because individual crystals sit far below what the eye resolves. What you notice at week six is not new dirt arriving, it is the accumulated layer finally reaching the density where it scatters light.
Salt is also hygroscopic, meaning it pulls moisture out of the air. Overnight, coastal humidity gives every crystal a film of water to sit in, and by dawn the layer has effectively rewetted itself and bonded a little more firmly. That daily wet and dry cycle is what turns a cosmetic film into a chemical problem over years.
Grading
We grade every restoration before quoting it, using a free test patch on one representative pane. The grade decides the method, the price, and whether restoration is worth doing at all.
Stage 3 is a replacement conversation. We would rather tell you that than sell a polish that leaves you with a distorted pane.
Between visits
Ten minutes with plain water every fortnight knocks the bulk of the salt off before it bonds. Tap water spots as it dries, so it is not a substitute for a clean, but it meaningfully slows the progression.
Irrigation mineral is far more aggressive than salt. On most coastal properties the sprinkler is doing more permanent damage than the ocean is.
Overflow at a gutter corner sends mineral-laden water down the wall and across the window below. That is a surprisingly common cause of a single badly stained pane.
Dry salt crystals are abrasive. Wiping them with a cloth grinds them across the surface. Flood the glass with water first, always.
Frequency by environment
How often your glass needs attention is not a preference, it is a function of what lands on it. Salt, pollen, irrigation mineral and construction dust each have their own season on this coast, and each wants a different answer.
January to February
Salt aerosol, no pollen
Winter is not a break on this coast. Salt deposition runs year-round, and the low winter sun angle makes an existing film far more visible from inside a room than it is in June. Oceanfront glass still wants its eight-week visit.
Oceanfront and sound-front: keep the 8 week cycle. Inland: nothing needed.
Late February to early May
Longleaf and loblolly pollen fall
The heaviest soiling window of the year, and the one most people waste money on. Cleaning glass during the drop is cleaning it twice: a fresh yellow layer lands within days. Wooded inland lots in Leland and Brunswick Forest take the worst of it.
Do not book a full clean in March. Wait for the drop to finish.
Mid-May
Pollen has stopped falling
The single most valuable visit of the year for inland and near-coastal homes. Glass, screens, tracks and sills all come back at once, after the pollen has stopped and before the summer humidity bakes anything onto the surface.
Inland Annual clients: this is your visit. Coastal Standard: visit one of two.
June to August
Sprinkler mineral, salt aerosol, dust
Irrigation runs daily and this is when hard water damage actually happens. A droplet landing on hot glass evaporates in seconds and leaves its calcium behind. Three summers of that turns surface deposit into etch that no wash will remove.
Walk your property mid-cycle and move any head that reaches the glass.
June to November
Wind-driven salt, sand and debris
After a named storm, the first 96 hours decide whether the deposit rinses off or bonds. Wind-driven salt gets forced into tracks, weep holes and screen mesh along with sand and pine straw. Left for a fortnight, packed wet sand in a slider track has to be dug out.
Post-landfall flush within 96 hours. Plan clients get priority slots.
September to November
Leaf drop, tannin staining, gutter load
Oak drip leaves a brown tannin film on glass and sills that plain water does not shift. This is also the point where gutters fill, overflow at the corners, and start sending mineral-laden water down the wall and across the window below.
Clear gutters first, then clean glass. Doing it the other way round wastes the visit.
December
Low sun, indoor months
Exteriors can wait. Interiors cannot, because the low December sun comes straight through the glass at eye level and shows every mark. Most of our December work is interior-only visits.
Interior-only visit at plan rate. Exteriors resume in the new year.
Frequency planner
Interval is a function of exposure, not of house size. Four questions about where the property sits and what lands on it will get you within a fortnight of the right answer.
Recommended interval
Every 22 weeks
About 2 visits a year
Closest plan: Coastal Standard
A planning guide, not a quote. A technician confirms the interval on the first visit and adjusts it by elevation where the water-facing side needs more than the street side.
Free stage test
A test patch on a representative pane tells you whether you are at stage 1, 2 or 3. It is free and it takes about twenty minutes.
Insured and IWCA. Certificates issued to your property manager on request.
