Cleaning a masonry surface helps improve a building's esthetics and can be part of a larger restoration or waterproofing project. Typically we utilize high pressure water and an environmentally safe cleaning solution.
Masonry is subject to efflorescence - salt deposits - which our normal cleaning solutions will not remove. We typically remove these salt deposits using a five percent solution of muriatic acid and water, followed by a thorough water flush. Keep in mind that if your building shows efflorescence, it could be a danger signal that your building's exterior requires masonry repairs.
