House washing in Sandy Springs means dealing with humidity-driven mold and mildew that builds up on siding faster here than in drier states. We soft wash your home's exterior with a low-pressure, siding-safe process that clears the growth without stripping paint or forcing water behind panels. Most homes are done in an afternoon, and you get a firm price before we start.
We start with a soft wash: a low-pressure application (150–300 PSI) of a cleaning solution designed to kill mold, mildew, and algae on contact. The solution needs 10 to 15 minutes of dwell time to actually break down the organic growth at the root, not just rinse the surface film.
After the dwell time, we rinse the entire exterior with clean water, working top to bottom so runoff doesn't re-deposit dirt onto areas we've already cleaned. Gutters, downspouts, and trim get the same treatment as the main siding, since those areas often hold the worst buildup.
Sandy Springs sits in a humid subtropical climate, and that moisture doesn't fully dry out between rains, especially on shaded walls or siding tucked behind mature trees. Mold and algae spores land on damp siding and take hold within days, then spread across the surface as long as moisture is present.
Pollen season makes it worse. Every spring, a yellow-green film coats every exterior surface in the area, and that film holds moisture against the siding even longer than normal rainfall would. By the time most homeowners notice staining, the growth has usually been building for a few months already.
Most house washes fall between $400 and $1,700, and where your home lands in that range depends on:
For siding, the answer is almost always soft washing. Vinyl and wood siding, brick, and trim are not built to withstand 1,300+ PSI up close — that level of force can peel paint, crack vinyl panels, or drive water behind the siding where it causes rot you won't see for months.
Pressure washing has its place on your property (driveways, concrete patios, composite decking), just not on the house itself. If a company offers to pressure wash your siding at full strength to save time, that's a shortcut that risks real damage.
No, that's the point of soft washing. We use 150 to 300 PSI, well below the pressure that risks peeling paint or driving water behind siding panels. The cleaning solution does the actual work of breaking down mold and mildew, not brute force.
Most single-family homes take 1.5 to 3 hours from setup to final rinse, depending on square footage and how many stories the house has. Homes with heavy mildew staining or hard-to-reach second-story areas can run longer.
Just clear patio furniture, planters, or anything breakable within about 10 feet of the exterior walls. We'll cover outdoor outlets and move small items like hoses or door mats ourselves.
We use a biodegradable solution and rinse plant beds with fresh water before and after application. Established shrubs and grass handle this fine; we'll flag it in advance if you have anything unusually sensitive, like a vegetable garden right against the foundation.
