How we clean it

Soft washCleaning method

Signs you need soft washing

  • Green, black or gray film on siding, especially on the north side
  • Black streaks running down the roof
  • Moss or lichen on shingles or tile
  • A musty smell around shaded walls
  • Pressure washing would damage the surface

Why it gets dirty

  • Algae, mold and mildew that grow in shade and humidity
  • Roof algae that feeds on the limestone filler in shingles
  • Pollen and dust that give growth something to hold on to
  • Sprinklers and gutters that keep walls damp

What you can do yourself

  • Trim back branches and shrubs that touch the house so walls can dry
  • Keep gutters clear so water doesn't overflow down the siding
  • Spot-clean small areas with a soft brush and mild detergent
  • Aim sprinklers away from the house

Common mistakes to avoid

  • Using too strong a mix, which can burn plants and fade surfaces
  • Using too weak a mix, which leaves growth alive and it returns quickly
  • Climbing ladders with a spray wand and chemicals
  • Mistaking soft washing for 'pressure washing on low'

  1. Identify the surfaces and the type of growth
  2. Pre-wet plants, cover sensitive fixtures and close windows
  3. Apply a solution mixed for the surface and let it dwell
  4. Rinse at low pressure from the top down

Serving Keene, NH and nearby towns

In New Hampshire, snow and slush that sit against the house leave a band of grime and mildew along the lower siding, and shaded north walls stay damp long after the thaw. A spring soft wash removes winter grime before it bakes on over the summer.

Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Soft Washing: frequently asked questions

How much does soft washing cost in Keene, NH?

Soft Washing typically costs $300-$800 for a typical single-family home exterior, and usually takes 2-4 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (555) 010-0000 for a free quote.

Do you use high pressure for soft washing?

Soft Washing is done with soft wash. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.

Is soft washing safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.

How often should I schedule soft washing?

Every 1-2 years for siding, every 3-5 years for roofs. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.

What if it rains on the day?

Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
