Professional Deck Pressure Washing & Restoration

Restore your deck’s natural beauty. Remove years of dirt, mold, and weathering. Prepare your deck for staining or sealing with professional pressure washing.

Why Your Deck Needs Professional Cleaning

Decks endure harsh conditions – sun, rain, snow, foot traffic, and organic growth. Over time, wood becomes gray, dirty, and covered in mold. Professional pressure washing:

  • Removes embedded dirt and grime
  • Eliminates mold, mildew, and algae
  • Strips away old stain or sealant
  • Exposes fresh wood underneath
  • Prepares surface for refinishing
  • Extends deck lifespan

Result: Beautiful, clean deck ready for staining or ready to enjoy as-is.

Benefits of Deck Pressure Washing

Removes Mold & Mildew
Organic growth makes decks slippery and dangerous. Professional cleaning eliminates safety hazards.

Prepares for Staining
Can’t stain over dirt and old finish. Pressure washing is essential prep work for beautiful, lasting stain jobs.

Prevents Wood Rot
Organic growth traps moisture, accelerating wood decay. Regular cleaning prevents costly rot repairs.

Restores Natural Beauty
Remove years of gray weathering. Expose the beautiful natural wood color underneath.

Extends Deck Life
Regular maintenance significantly extends deck lifespan. Cleaning costs $200-$400. Replacement costs $8,000-$15,000.

Increases Home Value
Clean, maintained decks boost property value and appeal to buyers.

Wood Deck vs Composite Deck Cleaning

Wood Decks (Cedar, Pine, Redwood):

  • Requires 1,200-1,500 PSI (low pressure)
  • Benefits from wood brightener
  • Can be stained/sealed after cleaning
  • May show grain raising (normal)
  • More dramatic transformation

Composite Decks (Trex, TimberTech):

  • Requires even lower pressure (500-1,200 PSI)
  • Specialized composite cleaners
  • Cannot be stained or sealed
  • Less prone to mold than wood
  • Cleaning restores color

Both benefit from professional cleaning, but techniques differ. Make sure contractor has experience with your deck material.

Should I Stain After Pressure Washing?

Yes, staining is highly recommended after cleaning wood decks.

Why Stain Your Deck:

  • Protects against moisture damage
  • Prevents UV damage from sun
  • Resists mold and mildew growth
  • Enhances natural wood beauty
  • Significantly extends deck lifespan

Timing: Wait 48-72 hours after pressure washing for wood to fully dry before staining.

Cost to stain: $2-$5 per square foot ($400-$1,000 for average deck)

Many contractors offer cleaning + staining packages with better pricing than separate services.

DIY vs Professional Deck Cleaning

DIY Deck Pressure Washing:

  • Risk of wood damage (splintering, gouging)
  • May cause “tiger striping” from uneven pressure
  • Equipment rental costs $50-$100/day
  • Physically demanding (lots of squatting)
  • Time-consuming for beginners
  • No warranty on results

Professional Deck Washing:

  • Expert technique prevents damage
  • Even, consistent cleaning
  • Professional wood cleaners and brighteners
  • Efficient (done in one day)
  • Warranty on work
  • Option to add staining
  • Costs $200-$400 (worth it for results and no damage)

Warning: Improper pressure washing can permanently damage wood decking. Many DIY attempts result in costly repairs.

How Often Should You Clean Your Deck?

Wood decks: Clean and re-stain every 2-3 years

Composite decks: Clean annually

Clean immediately if:

  • Visible mold or algae growth
  • Deck has turned gray from weathering
  • Planning to stain or sell home

Deck Cleaning Frequently Asked Questions

Will pressure washing damage my wood deck?
Not when done by professionals using proper PSI (1,200-1,500). DIY attempts with too much pressure commonly cause damage.

What’s the gray color on my deck?
That’s weathered wood. UV rays break down lignin, turning wood gray. Pressure washing + wood brightener restores natural color.

Can you remove old stain?
Yes, pressure washing strips most old stain and sealant. Heavy build-up may require chemical strippers.

How long before I can walk on my deck?
You can walk on it as soon as it dries (4-8 hours). Wait 48-72 hours before staining.

Will this smooth out rough, splintery wood?
Pressure washing helps, but severe splinters may need light sanding after cleaning.

Can you clean my fence at the same time?
Yes, most contractors offer fence cleaning as an add-on service at discounted rates.

What if it rains after cleaning?
Light rain is fine, but heavy rain may require re-cleaning. Contractors typically monitor weather forecasts.
