Estate exterior cleaning across Brookville slate, cedar, stone and extensive grounds, cleaned with methods chosen for the materials, not against them.
Brookville is one of the North Shores Gold Coast enclaves large wooded lots, long approaches and homes built to last generations. LIU Post sits within the community, and the surrounding streets carry the kind of housing stock that rewards knowing what youre cleaning.
Slate and cedar roofs, natural stone, original brick and lime-based mortar are common here. High pressure loosens slate, raises the grain on cedar and washes joints out of old masonry. The repair on any of them dwarfs the cost of the clean.
Mature trees keep north elevations damp for days after rain, which is exactly what algae, moss and lichen need. North-facing roof slopes streak with Gloeocapsa magma earlier than in open areas.
Long drives, courtyards, terraces, pool houses and walled gardens mean far more hardscape than a typical Nassau home, often in stone or older pavers.
Old Brookville, Upper Brookville, Muttontown and Old Westbury share the same estate profile.
Heavy tree cover means Brookville estates generally need more frequent attention than open Nassau properties.
Twice a year; the fall clearing is critical under mature canopy
Annually, shaded elevations sometimes more
Every two to three years, sooner on north slopes

Treated as it appears
On Brookville properties, most of whats on the building slate, cedar, stone, aged masonry would be damaged by high pressure. Soft washing applies cleaning solutions at low pressure, kills the growth at the root and rinses clean. It also lasts longer, because the spores are actually killed rather than just knocked off.
High pressure is reserved for the short list of surfaces that take it: concrete, some pavers and structural hardstanding.
Were members of the Power Washers of North America on the surfaces common around Brookville, that distinction isnt academic.

Most exterior damage were asked to fix was caused by cleaning. Knowing which surfaces take pressure and which need chemistry is the entire job.
Accountable to an industry body on method, insurance and environmental practice. Very few Long Island companies hold it.
Landscaping pre-wet and covered, fixtures shielded, everything rinsed after.
Certificates available on request.
Yes, and both must be soft washed. High pressure loosens and cracks slate and raises the grain on cedar. We use low pressure with cleaning solutions that kill algae and moss at the root, then rinse. These are among the most expensive roofs on Long Island to repair.
Yes. Long drives, courtyards, pool houses, outbuildings and stone detailing are standard estate work for us, and we price the whole property rather than just the main house.
Almost always irrigation. Mineral content in the water oxidizes into rust-colored staining on stone, stucco and concrete. It needs specific treatment, not pressure, and it removes cleanly if caught before it sets.
