Pressure washing costs in Jacksonville

A federal guide to cleaning old brick and stone sits inside the review for houses in Jacksonville's historic districts. Jacksonville's 2026 review matrix holds painting work to the National Park Service's Preservation Brief 1, which covers cleaning and water-repellent treatments for historic masonry. Work that fits the brief can be approved by staff. Work that doesn't goes before the Jacksonville Historic Preservation Commission.

Here's what that brief asks of a wash. Use the gentlest method that still gets the wall clean. With water, start very low, at 100 psi or below, even with a garden hose. Step up only as needed, and generally no higher than 300 to 400 psi. If a spot needs scrubbing, use natural or synthetic bristle brushes, never metal. Metal can scratch the face and leave bits behind that stain.

The brief also asks for patience. Clean a small test spot first, and judge it only once the masonry has dried all the way. A full year of weather on the test patch would be ideal. If that's not possible, give it at least a month or two before cleaning the whole house.

Plan the products along with the pressure. Under painting, the matrix lists chemical treatments of masonry, and painting masonry that has never been painted, as work for the full commission, not staff.
