Spring Pressure Washing in Richmond: Beating Humidity and Mildew

If you’ve noticed a green tinge creeping across the shaded side of your Richmond house, you’re not imagining it. Central Virginia’s warm, humid climate is ideal for mildew, algae, and mold on exterior surfaces — and spring is when it really takes hold. Here’s how to think about pressure washing your Richmond home so it looks sharp without damaging anything.

Why Richmond exteriors go green

Richmond’s humid subtropical climate means long, damp, shady conditions for much of the year. North-facing walls, tree-shaded siding, and anything that stays wet — decks, fences, the concrete under a downspout — grow a film of algae and mildew. It’s mostly cosmetic at first, but left alone it holds moisture against the surface and can shorten the life of paint, wood, and sealant.

Richmond’s mature tree canopy makes it worse: beautiful shade, but also constant organic debris and less sun to dry surfaces out.

What’s worth cleaning — and when

Best time: spring through early summer, once the worst of the pollen has passed. It clears the winter’s mildew buildup and resets the house before the hot, humid stretch.

Surfaces that benefit:

• Siding — vinyl, brick, and fiber-cement all collect mildew on shaded elevations.
• Driveways and walkways — concrete grows algae and collects oil and tire marks.
• Decks and fences — wood goes gray and slick with mildew; cleaning (and resealing wood) extends its life.
• Patios and porches — especially under trees.

Pressure washing done wrong can damage your home

This is the part DIYers get bitten by. Too much pressure, or the wrong technique, will:

• Etch and pit concrete.
• Gouge or splinter wood decking.
• Force water behind siding, where it causes rot and mold.
• Strip paint and damage sealant.

Different surfaces need different pressure and, often, a “soft wash” approach with the right cleaning solution rather than brute force. Knowing which is which is most of the job. Our professional pressure washing matches the method to each surface so your home gets clean without getting damaged.

A quick maintenance rhythm for Richmond homes

• Spring: full exterior wash to clear winter mildew.
• As needed: spot-clean the shaded, north-facing areas that green up first.
• Every few years: clean and reseal wood decks and fences.
