Glass in Harbor Island

What Harbor Island does to windows

Oceanfront and near-beach glass films over faster than anywhere else in Beaufort County. Onshore wind carries a fine salt aerosol that dries into a haze within weeks of a cleaning, and sea breeze pushes it well back from the dune line.

A single visit looks wonderful for a few weeks — and then the Lowcountry takes it back. That's why membership is the heart of Sunday's work in Harbor Island: your glass stays ahead of the buildup, cleaned on a rhythm matched to salt haze off the Atlantic, so it never reaches the point where you notice it's dirty. And when the job is a project rather than a rhythm — a post-construction clean, a pre-listing detail, a one-time cleaning — we handle those too.

Every full visit covers exterior and interior glass, screens removed and washed, tracks and sills vacuumed and wiped, and a walk-around check for failed seals and early hard-water etching. Between-visit touch-ups — a storm that throws salt across the porch glass, a painter's overspray — are part of the membership, not an extra charge.
