Professional Deck & Fence Cleaning | Northern Illinois
Patio and Fence Cleaning
Your deck and fence represent significant investments in your outdoor living space—often $10,000-$30,000 or more. Yet Northern Illinois weather, moisture, and neglect can destroy these wood structures in just a few years if not properly maintained. Mold, mildew, algae, and UV damage don’t just look bad—they rot wood from the inside out, leading to expensive repairs or complete replacement.
Blues Pressure Washing specializes in deck and fence restoration that removes years of buildup, restores natural wood beauty, and prepares surfaces for staining or sealing. Our careful cleaning process removes destructive organic growth without damaging wood fibers, extending the life of your outdoor structures significantly.

Why Professional Deck & Fence Cleaning Matters
Preventing Wood Rot & Deterioration
Mold, mildew, and algae don’t just discolor wood—they actively destroy it:
Organic Growth Roots Into Wood
Mold and algae send microscopic roots deep into wood grain, breaking down protective lignin and cellulose. This weakens structural integrity and accelerates rot.
Moisture Retention
Organic growth traps moisture against wood surfaces. Constant dampness promotes rot, particularly in horizontal deck boards and fence pickets.
UV Protection Loss
Dirty, weathered wood loses natural UV protection. Sun damage penetrates deeper into unprotected wood, causing cracking, splitting, and structural failure.
Preparing for Stain or Sealer
You cannot properly stain or seal dirty, weathered wood. Stain applied over dirt and mildew:
- Fails to penetrate properly
- Peels and flakes within months
- Looks blotchy and uneven
- Provides no protection to underlying wood
Professional cleaning creates the clean, porous surface required for stain absorption and long-lasting results.
Eliminating Safety Hazards
Algae-covered deck boards become dangerously slippery when wet, particularly on shaded decks and stairs. This creates liability issues and genuine safety risks for family and guests.
Restoring Aesthetic Appeal
Weathered gray wood with black mildew stains looks neglected and decreases property value. Clean wood with restored natural color dramatically improves outdoor space appearance and makes your entire property look better maintained.
Extending Structure Lifespan
A properly maintained deck or fence can last 20-30 years. Neglected structures often fail at 10-15 years, requiring expensive rebuilding. Regular cleaning is affordable insurance against premature replacement.
Surfaces We Clean & Restore
Wood Decks
Cedar Decks
Cedar’s natural beauty and rot resistance make it popular for decks, but it still requires maintenance. We restore cedar’s rich color and aromatic properties while removing weathering and organic growth.
Pressure-Treated Pine
The most common deck material. Pressure-treated lumber resists rot but still requires cleaning to remove mold, mildew, and the gray weathered appearance that develops over time.
Redwood Decks
Premium redwood offers beautiful coloring and natural resistance to decay. Our gentle cleaning restores redwood’s distinctive appearance without damaging softer wood fibers.
Exotic Hardwoods (Ipe, Tigerwood, Cumaru)
These dense tropical hardwoods require specialized cleaning techniques. Too much pressure damages expensive materials; too little leaves dirt behind. We understand the balance required.
Composite Decking (Trex, TimberTech, Azek)
Composite materials don’t rot, but they still develop mold, mildew, and algae staining. We use appropriate low-pressure techniques and approved cleaning agents for composite materials.
Fences
Privacy Fences
Six-foot privacy fences develop heavy organic growth on shaded sides. We clean both sides of fence boards, posts, and caps, restoring appearance throughout.
Picket Fences
Traditional picket fences with intricate spacing require detail work to clean between pickets, along rails, and around decorative elements.
Split-Rail Fences
Rustic split-rail fences benefit from cleaning that removes moss, lichen, and weathering while maintaining their natural appearance.
Shadowbox Fences
Alternating board patterns on shadowbox fences create cleaning challenges requiring attention to both sides and all surfaces.
Pergolas & Gazebos
Outdoor structures with overhead elements face unique challenges:
- Bird droppings on horizontal surfaces
- Spider webs in corners and joints
- Moss growth on shaded beams
- Algae on posts and railings
We clean all surfaces, joints, and decorative elements completely.
Deck Railings & Stairs
These high-touch, high-visibility areas need special attention:
- Handrails get frequent contact and show dirt quickly
- Spindles and balusters have intricate surfaces trapping dirt
- Stairs develop slippery algae creating safety hazards
- Railing caps collect debris and water
Outdoor Furniture & Structures
We also clean:
- Wooden patio furniture
- Deck storage boxes
- Plant stands and decorative elements
- Wooden planters and raised beds
Our Deck & Fence Cleaning Process
Step 1: Surface Inspection & Assessment
Before beginning, we evaluate:
- Wood type and condition
- Extent of weathering and damage
- Previous stain or sealer condition
- Problem areas (rot, loose boards, structural issues)
- Appropriate cleaning method and pressure
This assessment ensures we use proper techniques for your specific wood and situation.
Step 2: Pre-Cleaning Preparation
Property Protection
We protect landscaping, siding, windows, and outdoor furniture from overspray and cleaning solutions.
Debris Removal
We sweep or blow off loose debris, leaves, and dirt before wet cleaning begins.
Repairs Identification
We note any repairs needed (loose boards, popped nails, damaged sections) so you can address them before staining.
Step 3: Wood Cleaning Solution Application
We apply professional wood cleaning solutions designed specifically for exterior wood:
For Heavily Soiled Wood:
Oxygenated cleaners that brighten wood while killing mold, mildew, and algae.
For Weathered Gray Wood:
Wood brighteners that restore natural color by removing oxidized surface layers.
For Previously Stained Wood:
Specialized strippers that remove old failing stain without damaging wood fibers.
Solutions dwell for 10-20 minutes, penetrating into wood grain and breaking down years of accumulation.
Step 4: Controlled Pressure Washing
Using appropriate pressure for wood type:
Soft Woods (Pine, Cedar, Redwood): 500-800 PSI
Hard Woods (Exotic decking): 800-1,200 PSI
Composite Materials: 1,200-1,500 PSI
Critical Technique:
We always wash with the wood grain, never across it. Cross-grain washing damages wood fibers and creates a “fuzzy” surface that resists stain.
Consistent Distance:
Maintaining proper distance from the surface prevents wood fiber damage while ensuring thorough cleaning.
Step 5: Brightening Treatment (Optional)
For wood being prepared for staining, we often apply a brightening solution after cleaning:
- Neutralizes cleaning solution pH
- Opens wood pores for better stain penetration
- Restores natural wood color
- Creates ideal surface for staining
Step 6: Final Rinse & Debris Removal
After cleaning:
- Thorough rinse to remove all cleaning agents
- Flush debris from between deck boards
- Clear drainage areas
- Remove any loosened material
Step 7: Drying Time & Staining Preparation
Drying Requirements:
Wood must dry completely before staining—typically 48-72 hours in good weather, longer if cool or humid.
Surface Check:
Before staining, we verify wood moisture content is below 15% and surface is clean and ready for coating.
Understanding Wood Cleaning Chemistry
Why Water Alone Isn’t Enough
Pressure washing with plain water removes surface dirt but doesn’t:
- Kill mold and mildew spores
- Remove tannin staining
- Brighten weathered gray wood
- Prepare wood properly for staining
Professional wood cleaners contain:
- Sodium percarbonate (oxygenated bleach) to kill organic growth
- Surfactants to penetrate wood grain
- Brightening agents to restore color
- pH buffers to protect wood fibers
The Difference Between Cleaning and Stripping
Cleaning:
Removes dirt, mold, and surface contamination while leaving intact stain or sealer in place. Used for maintenance cleaning between re-coating.
Stripping:
Removes old failing stain completely, exposing bare wood for fresh stain application. Required when old stain is peeling, flaking, or deteriorating.
We assess your wood and recommend the appropriate approach.
Deck & Fence Staining Services
Why Stain After Cleaning
Clean wood is vulnerable wood. After removing protective buildup, wood is exposed to:
- UV damage from sunlight
- Moisture absorption
- Rapid organic growth return
- Accelerated weathering
Staining within 2-4 weeks of cleaning protects your investment and maximizes stain lifespan.
Types of Wood Stain We Apply
Transparent Stains
Show wood grain completely while providing UV protection. Require most frequent re-coating (every 1-2 years) but showcase wood beauty.
Semi-Transparent Stains
The most popular choice. Provide good UV protection while still showing wood grain and texture. Typically last 2-4 years.
Semi-Solid Stains
More pigment coverage, some grain visibility. Excellent UV protection and durability (3-5 years). Good for older, weathered wood.
Solid Stains
Maximum protection and coverage, similar to paint. Hide wood grain entirely but provide longest lifespan (5-7 years). Best for severely weathered wood.
Stain Application Process
- Verify Complete Dryness: Moisture meter confirms wood is below 15% moisture
- Final Surface Check: Ensure wood is clean, smooth, and ready
- Product Application: Brush, roll, or spray depending on surface and stain type
- Back-Brushing: Work stain into wood grain for deep penetration
- Second Coat (when appropriate): Applied 24-48 hours after first coat
- Curing Time: Allow full curing before heavy use (48-72 hours minimum)
Composite Decking Cleaning
Special Considerations for Composite Materials
Composite decking (Trex, TimberTech, Azek, etc.) doesn’t rot, but it still develops:
- Mold and mildew growth (especially on shaded boards)
- Algae accumulation creating slippery surfaces
- Tannin bleeding from embedded wood fibers
- General dirt and environmental buildup
Our Composite Cleaning Approach
Manufacturer-Approved Methods
We follow specific manufacturer guidelines for each composite brand to avoid voiding warranties.
Appropriate Pressure
Higher pressure than wood (1,200-1,500 PSI) but still controlled to prevent surface damage.
Specialized Cleaners
Composite-specific cleaning solutions that won’t damage plastic components or fade colors.
Attention to Gaps
Debris accumulates between composite boards. We clean gaps thoroughly to prevent organic growth and drainage problems.
Northern Illinois Deck & Fence Challenges
Harsh Winters
Freeze-thaw cycles, ice, snow, and road salt tracked onto decks accelerate deterioration. Spring cleaning removes winter damage and prepares wood for warm weather.
Humid Summers
High humidity creates perfect conditions for mold and mildew growth. Shaded decks and north-facing fences develop heavy organic buildup requiring professional treatment.
Mature Trees
Northern Illinois’ beautiful tree canopy means:
- Constant leaf and debris accumulation
- Heavy shade promoting mold growth
- Tannin staining from leaves
- Sap and pollen deposits
Seasonal Pollen
Spring pollen coats outdoor surfaces with yellow-green film that attracts moisture and promotes algae growth.
Recommended Cleaning & Maintenance Schedule
Annual Cleaning (Minimum)
All decks and fences benefit from at least annual cleaning, ideally in spring before outdoor season begins.
Every 2-3 Years: Clean & Restain
For stained/sealed wood, plan to clean and re-coat every 2-3 years to maintain protection and appearance.
Signs Your Deck/Fence Needs Immediate Attention
Water Absorption Test:
Sprinkle water on deck boards. If water soaks in immediately rather than beading up, protection is gone and re-staining is urgently needed.
Visible Mold/Mildew:
Black or green organic growth indicates cleaning is overdue. Left untreated, this growth causes permanent damage.
Graying/Weathering:
Natural wood that’s turned gray has lost UV protection and is deteriorating. Clean and stain before damage worsens.
Peeling/Flaking Stain:
Failing stain provides no protection. Strip, clean, and re-stain to prevent wood damage.
Splinters & Roughness:
Wood that’s rough and splintery is breaking down. Clean and seal urgently to prevent further deterioration.
Frequently Asked Questions – Deck & Fence Cleaning
Will pressure washing damage my deck?
When done correctly with appropriate pressure, techniques, and experience, no. We adjust pressure based on wood type and condition, always wash with the grain, and maintain proper distance from surfaces. Improper pressure washing (too much pressure, wrong angle, inexperienced operator) can damage wood, which is why professional service matters.
How long does deck cleaning take?
Most average decks (12×16 to 16×20) take 2-4 hours to clean thoroughly. Large multi-level decks may take 4-6 hours. Fences vary widely based on linear footage and height—typically 1-3 hours for average residential privacy fences.
When is the best time to clean my deck?
Spring (April-June) is ideal—removes winter damage and prepares for outdoor season. Early fall (September) also works well for cleaning before winter. Avoid extreme heat (wood dries too fast for stain) and cool weather (extended drying time).
Do I need to stain after cleaning?
Not immediately, but staining within 2-4 weeks is highly recommended. Clean, bare wood is vulnerable to UV damage, moisture, and rapid organic growth return. Staining protects your investment and the cleaning you just paid for.
Can you remove old stain that’s failing?
Yes. Severely failing stain requires stripping rather than simple cleaning. We use specialized stain strippers that remove old coatings without damaging wood, preparing surfaces for fresh stain application.
How long before I can use my deck after cleaning?
Allow 24-48 hours after cleaning for wood to dry before normal use. If you’re staining after cleaning, allow 48-72 hours of drying before stain application, then another 24-48 hours after staining before heavy use.
Will cleaning remove gray weathered appearance?
Yes. Professional wood brighteners restore much of wood’s natural color by removing oxidized surface layers. Severely weathered wood may not return to like-new appearance but will look dramatically better.
Can you clean composite decking?
Absolutely. Composite materials require different techniques than wood, but we clean all major composite brands following manufacturer guidelines.
My fence is too tall for me to clean—can you handle it?
Yes. We have equipment to safely clean fences up to 8 feet tall and can handle both sides of privacy fences, including tops of posts and caps.
How much does deck cleaning cost?
Pricing depends on:
- Deck size and configuration
- Current condition
- Wood type
- Fence linear footage (if included)
Typical ranges:
- Average deck cleaning: $200-$400
- Large/multi-level decks: $400-$700
- Privacy fence cleaning: $150-$400 (depending on length)
