What St. Augustine properties need most: Historic coquina and tabby are soft, porous shell-based materials. Pressure does not clean them — it erodes them permanently. There is no repair, only replacement with material that no longer matches.
Anything in the historic district gets treated as unrepairable until proven otherwise: low-pressure application, careful solution selection, and a documented test area first. Outside the old town, Anastasia Island and the newer inland developments are ordinary coastal work — salt, algae and shingle roofs.
Why St. Augustine properties get treated differently
These are the details that decide which method, which pressure and which solution strength a property gets. They are not the same across Jacksonville.

Shade: Partial shade means the north side stays damp longer than the rest. Full salt exposure — it settles on every windward surface and holds moisture against it.
Water supply: Municipal supply, so irrigation rust is less common than in Clay County.
Community rules: Covenants vary street by street, from historic-district rules to none at all.
We also work regularly around the historic district, Anastasia Island, US-1. Those are geographic reference points only — no affiliation or endorsement is implied.

Common questions from St. Augustine homeowners
When is the best time of year to book in St. Augustine?
Late spring, once the oak pollen has finished falling — usually the second half of April here. Washing before pollen season ends means doing it twice.
Being this close to the ocean, there is a second consideration: salt builds year-round rather than seasonally, so a lot of St. Augustine owners rinse in autumn as well, particularly on windward elevations and metal fixtures.
How often will my St. Augustine home need it?
Around twelve months for most St. Augustine properties. Partial shade means the north side needs attention before the rest of the house does.
The reliable signal is a visible colour difference between the shaded elevation and the sunny one. Full frequency guide by surface.
Does living near the ocean really change anything?
More than most people expect. Salt is hygroscopic — it pulls moisture out of the air and holds it against whatever it has settled on. A salt-loaded wall stays damp longer than a clean one, and damp surfaces grow algae faster.
It also attacks fixtures, fasteners, light fittings and metal roof seams long before it does anything visible to the walls. A rinse is genuinely maintenance here, not just appearance. See our guide to salt air and coastal exteriors.
