Years of grime, mold, and algae — gone in a day. Green Leaves provides professional soft-wash and pressure washing services for NOVA homes, driveways, patios, and decks.
Power washing is one of the most cost-effective ways to dramatically improve your home's appearance. Green Leaves provides professional pressure washing and soft-washing services for Northern Virginia homeowners — cleaning away years of algae, mold, mildew, and organic staining safely and effectively.
We use the right technique for each surface — high pressure for concrete and hardscape, low-pressure soft-wash with biodegradable detergents for siding, roofs, and painted surfaces. This protects your property while delivering far better results than DIY pressure washing.
Not all surfaces should be blasted with high-pressure water. We use true soft-washing (low pressure + surfactant) for siding, roofs, and painted wood — this kills algae and mold at the root level rather than just blasting the surface, so results last 3–5x longer than pressure washing alone. Hard surfaces like concrete, pavers, and stone get high-pressure treatment for maximum stain removal.
All our cleaning solutions are biodegradable and safe for surrounding plants, pets, and lawn areas after rinsing.
Most Northern Virginia homeowners benefit from annual driveway cleaning, especially given our humidity and tree canopy that promotes algae growth.
Yes — soft washing is actually safer for vinyl siding than pressure washing, which can force water behind panels. Our low-pressure + detergent method removes algae and oxidation without risk.
A standard two-car driveway typically takes 1–2 hours. Full-house exterior cleaning takes a half to full day depending on square footage.
Absolutely — deck washing before staining is critical for proper adhesion. We recommend our wood-safe cleaning treatment to open the grain before any stain application.
The right timing matters more than the product. Here's the schedule we actually follow across Northern Virginia — based on our zone 7 climate, clay soil, and cool-season lawns.
Most NOVA lawns are cool-season tall fescue, and fescue does almost all of its root-building in fall. The two most valuable feedings are early September and again in late October to early November. A single light feeding in April is fine, but skip heavy nitrogen in summer — it stresses fescue and feeds crabgrass instead of your grass.
Late August through mid-October is the prime window. The soil is still warm enough for fast germination, the nights are cooling, and there's far less weed competition than in spring. Aim to get seed down by mid-September for the strongest fill-in before winter. Spring seeding (March–April) is a distant second and usually gets crowded out by crabgrass.
The main mulch application is mid-to-late spring — April into May — once the soil has warmed and early weeds are cleared. Refresh in fall if beds look thin. Keep mulch 2–3 inches deep and pull it a few inches back from trunks and stems; “mulch volcanoes” piled against bark trap moisture and cause rot.
Wait until after the average last frost — around April 15–20 — before putting out warm-season annuals like petunias, marigolds, and impatiens. Cool-season color such as pansies and violas can go out in late March or again in fall. Perennials, trees, and shrubs establish best planted in fall (September–October) or early spring, and spring bulbs like tulips and daffodils go in the ground in October–November.
Core-aerate cool-season lawns in the fall — September into October — ideally right before overseeding so the seed drops into the holes. Fall aeration relieves the summer compaction that NOVA's heavy clay builds up and sets up thick spring growth. Spring aeration is possible but can open the door to summer weeds.
