Giovanna from Holmdel, NJ has been a Green Sun Energy Services client since May of 2026. We soft washed the two-storey house at the end of that month, working at low pressure and letting a sodium hypochlorite and surfactant solution do the cleaning. The parts of a house that need this most are the parts rain never reaches: under the eaves, the soffits, the shaded walls that stay damp and out of the sun. Those hold algae and grime year after year while everything the weather touches looks passable, which is how a house can seem perfectly clean from the street and still be visibly dirty from ten feet away.

Exterior cleaning questions from Holmdel homeowners
Does soft washing use bleach, and is that bad for a house?
Sodium-hypochlorite-based chemistry is widely used for biological growth, and chlorine-based treatment is specifically recognized in the published asphalt-roof cleaning guidance from both the industry association and the shingle manufacturers. Like any cleaning product it can damage materials if misused, so what matters is controlling the concentration, the exposure time, the overspray, the rinse and the protection of planting.
What should a Holmdel homeowner look for in an exterior cleaning company?
One that treats exterior cleaning as a material-specific process rather than as pressure washing. That means inspecting the property, identifying both the surfaces and the contamination, protecting the landscaping before and after, applying at low pressure on anything delicate, choosing the chemistry for the material, controlling the dwell time, rinsing appropriately, following the shingle manufacturer's roof-cleaning guidance and the siding manufacturer's instructions, treating windows carefully, protecting paver joints, working safely off ladders, cleaning up, and walking the finished job with the homeowner. The useful question is not who has the strongest machine but whether the company knows what the house is made of and the safest way to clean each part of it.
What happens before the cleaning starts?
A walk of the property first: the condition of the surfaces, the stains actually present, the landscaping, the windows, exterior electrical fittings, access, and anything delicate enough to need different treatment. Sensitive planting is pre-soaked with fresh water before any cleaning solution is applied.
